Background. In the past decades, the abandonment of traditional land use practices has determined landscape changes inducing reforestation dynamics. This phenomenon can be contrasted with rewilding practices, i.e., the reintroduction of animals that may promote the recovery of landscape diversity. In this study, we explore the dynamics of expansion of two reintroduced populations of wild ungulates, Italian roe deer (Capreolus capreolus italicus) and red deer (Cervus elaphus), assessing their contribution in the recovery of landscape diversity. Methods. By using direct and indirect information on the two species, collected by nocturnal and diurnal surveys and camera trapping, we modelled a habitat suitability map, and estimated the density and distribution of the populations. We also performed a land use changes analysis, combining the presence of wild ungulates and livestock. Results and Discussion. We demonstrated that deer dispersed gradually from their release location, increasing in population size, and this occurred in the entire study area. Moreover, we show that areas with lower grazing density are significantly affected by forest encroachment. A possible interpretation of this result could be that wild grazers (roe deer and red deer) prefer semi-open areas surrounded by the forest. This, in association with other factors, such as domestic grazing, could be one of the main responsible in maintaining landscape mosaic typical of the Apennine mountain, confirming the value of grazers as a landscape management tool. Moreover, we show the possibility to conserve through reintroduction the vulnerable C.c. italicus. [ABSTRACT FROM AUTHOR]

- Abstract
We investigate the seismic structure of the mantle wedge of the Apennines subduction zone (Central Mediterranean) using teleseismic receiver function (RF). We inverted RF for both isotropic and anisotropic properties of the mantle wedge, from below the overriding Moho to the “plate boundary”, i.e. the interface that separate the slab from the mantle wedge. Given the distribution of the seismic network, we are able to map out the change in the elastic properties at the transition between southern apennines and the Calabrian arc, given by the change in the subduction style (i.e from the subduction of continental materials to oceanic plate). We found that the anisotropy in the mantle wedge is similar between all seismic stations, generally highly anisotropic (> 10%), with a direction of the symmetry axis that rotates clockwise from North to South, following the Calabrian arc geometry and likely indicating the mantle flow driven by the slab retreat. The elastic properties of the subducted crust are more heterogeneous. To the North, the subducted crust shows a highly anisotropic (> 10%) behavior, and it occurs at larger depth (around 70 km depth), where to the South anisotropy is less intense (around 7%) and the subducted crust is shallower (around 60 km depth). These results point out a change in the subduction style that can be given by either a change in the metamorphic phase (more evolved blueschist facies stage to the North, initial greenschist facies stage to the South) or a different origin for the subducted materials (continental to the North and oceanic to the South). The differences in the anisotropic behavior of the subducted crust are reflected in the topography of the plate boundary, which becomes shallower from North to South, suggesting the existence of either a step in the slab topography or a more gentle ramp.

Question: Vegetation around the alpine–treeline ecotone faces changes in both climate and land use (i.e. grazing abandonment). Broad‐scale shrub encroachment is considered an effect of these changes, but it remains unclear how this process is mediated by local‐scale environmental heterogeneity. Our goal is to determine which local‐scale environmental factors shape the spatial distribution and temporal trends of alpine dwarf shrub vegetation dominated by Juniperus communis in Mediterranean mountains. Location: Three sites in the Central Apennine Mountain Range (Italy): Mt. Terminillo, Mt. Duchessa and Mt. Ernici. Methods: Combining a set of environmental variables obtained at a fine scale (25‐m resolution) from multi‐year remote sensing imagery and field‐collected vegetation data, we modelled the occurrence and cover of Juniperus communis‐dominated dwarf shrubland, as well as its change over time, as a function of local climate, topography and land use, using linear and generalized mixed effects models. Results: Over a period of almost 60 years (1954–2012) shrubland occurrence increased by 12% and shrubland cover by 10% in our study sites. Its current distribution and change over time appear to be strongly shaped by the joint influences of fine‐scale topography, above‐ground biomass, land use and microclimate. Shrublands have been favoured locally in areas with harsher alpine environmental constraints and stronger resource limitations. Conclusions: Our study shows that in the Mediterranean high‐mountain environment J. communis dwarf shrubland acts as a stress‐tolerant pioneer vegetation, occurring in areas that are otherwise sparsely vegetated. Contrary to our expectations, at fine scales, warmer temperatures and the regional decline in grazing did not favour shrub encroachment. Despite increasing overall, J. communis shrubs have little competitive ability to successfully encroach grasslands, and remain restricted to less‐productive areas. Our results confirm that fine‐scale environmental heterogeneity can strongly influence shrub distribution and dynamics, thereby modulating future responses in evolving alpine ecosystems.

The Boiano Basin is one of the largest Quaternary intermontane basins of the central‐southern Apennines within one of the most tectonically active areas of the Mediterranean region. In order to reconstruct its entire Quaternary stratigraphic, tectonic, and palaeoenvironment evolution, lithofacies and palaeomagnetic analyses have been performed on a 900 m‐deep borehole (CP1) drilled in the southwestern sector of the basin. The Quaternary succession consists of an alternating of alluvial fan and fluvial–marshy deposits for a total thickness of 240 m, unconformably laying on Lower Miocene deposits of the Sannio Unit, thrusted on upper Miocene deposits of the Molise Flysch. In addition, the stratigraphic study and facies distribution of 29 intermediate and shallow wells drilled in the basin, allowing us to define the thickness and lithofacies variations of the Quaternary sedimentary units inside the entire Boiano Basin in the sector of Campochiaro alluvial fan. Our results demonstrate that the Boiano Basin infilling started during the late Early Pleistocene (c. 1.1 Ma) and developed with variation in lithofacies distribution and thickness. The first depositional unit (Early Pleistocene–early Middle Pleistocene in age) was palustrine and fluvial–marshy, the second (Middle Pleistocene in age) was characterized by the occurrence of the first cycle of alluvial fan deposition, the third (late Middle Pleistocene in age) was newly palustrine and fluvial marshy and, finally, the fourth recorded two cycles of alluvial fan deposition (late Middle Pleistocene and Late Pleistocene in age, respectively), interspersed by short periods of palustrinity, tephra layers deposition, and palaeosols development. The study allows the hypothesizing that the Quaternary infilling was accommodated within a graben (or semigraben) structure, affected mainly by extensional fault systems localized in the inner part of the basin and secondly by fault systems bounding the basin.

We address the modeling of spatial distribution of coseismic landslides, based on an empirical approach applied to both recent and historical well-documented events. We analyze a dataset of 11 historical and recent normal faulting earthquakes in the Italian Central Apennines. Firstly, making use of a kernel density estimator approach, we calculated the regression between the extent of the maximum area affected by landslides (A; km2) and Mw, on the combined dataset of recent and historic earthquakes: Log A = (1.0397 Mw)–3.9288. Then, for recent earthquakes only, we analyzed the attenuation regression of landslide density (Dens; no. of landslides/km2) with distance from surface fault trace (Dfault; meters): Dens = 0.3661 × exp (− 5.053 Dfault). Historical events, still presenting systematically lower values of landslide densities, can be regressed on the same functional form resulting in a similar factor of attenuation with distance but with a different scaling factor. We thus argue that empirical regressions on historical earthquake-triggered landslides can be successfully exported elsewhere if a well-documented catalog is present and a calibration with several recent events can be done.

Context: The importance of societal factors in shaping forest area, structure and composition through economic activity, policy, governance, and population changes is frequently acknowledged in ecologic studies, however the specific socioeconomic factors that lead to land use change through time are rarely articulated. Objectives: We present a consilience-driven approach for integrating socioeconomic and paleoecologic data to explore land use legacies and interpret causes of past abrupt environmental change. Methods: We combine paleoecologic history reconstructed from pollen analysis of lake sediments and contemporary historical narratives of socioeconomic change developed from archival sources illustrated by three case studies from two sites in the Italian Apennines. Results: We found that in the Rieti Basin, central Italy, between 850 and 900 AD (coeval with the beginning of the Medieval Climate Anomaly—MCA), under the new Carolingian rule, the imperially sponsored monastery at Farfa consolidated small landholdings, leading to more active land management and significant forest loss for agricultural activities. In contrast, at Pollino in southern Italy between 1050 and 1100 AD, also during the MCA, Norman conquest helped to convert a deforested landscape into an actively managed fir forest for timber needed for construction. At both sites, depopulation and land management between 1350 and 1400 AD caused by the Black Death, led to forest rewilding, however each site took a different trajectory. Conclusions: The studies presented offer examples of how the integration of detailed historical narratives with high-resolution paleoecologic reconstructions can provide a more nuanced examination of the interrelationship between societal factors and climate forcing in shaping land-use legacies and has the capacity to illuminate the link between specific human pressures and pathways of ecological change over many centuries.

SEA level ,ALTITUDES ,COASTS ,RIFTS (Geology) - Abstract
Elevations of numerous coastlines have been measured on wide areas of Italy (central Apennines and Sardinia) and Spain. If we consider small areas, the coastlines are clear and are at precise, distinct elevations; so, it can be inferred that the sea level changes had long stillstands and rapid changes. Sea level changes have taken place cyclically every 2528 years, giving rise to two main level stillstands, a longer one of about 2200 years and a shorter one of about 160 years. For the area of the Apennines nine elevation sequences relevant to as many zones have been recorded. Each of these zones had an uplift different from those of the other zones. By isolating the differences between couples of elevations which are in common among the various zones and therefore have an eustatic meaning, it was possible to subtract the effects of the uplifts and reconstruct a single, common succession of sea levels that are the traces of a great transgression started 270 Ka and culminated shortly afterwards at an altitude of 822 m above the present level. The same succession was also recognized in Sardinia and Spain, where no correction for uplifting was necessary, showing that these two zones were altimetrically stable in the examined time frame. In the Apennine area the boundaries of the nine zones are outcroppings of normal fault surfaces. [ABSTRACT FROM AUTHOR]

- Abstract
A comparative analysis of environmental conditions between Alpine and Apennine lakes/ponds which represent different faces of European mountain regions was conducted. The data set was created on the basis of previous works carried out by national and international institutions including biological, physical-chemical, geographic, and precipitation data from 27 lakes/ponds placed at altitudes ranging from 2334 +/- 294 m a.s.l. (in the Alps) and 1541 +/- 154 m a.s.l. (in the Apennines), with mean maximum depths of about 5.5 +/- 4.6 m. A specific focus was dedicated to chironomids as outstanding sentinels for local and global changes in habitat conditions. Species richness and Taxonomic Distinctness Indices were applied to lakes/ponds macroinvertebrates to highlight differences in the biodiversity of the two areas. Subsequently, associations between descriptors of the mountain region climate, lithology, water chemistry, lake morphology, geography, macroinvertebrate assemblage richness, and distinctness were examined through Principal Component Analysis, Analysis of Variance, and Non-metric Multi-dimensional Scaling. Results showed strong positive correlations between mean annual precipitation and temperature with lake macroinvertebrate biodiversity as a whole and with chironomid in particular. Thus, these shore habitats face a threat under climate change conditions (impacting thermal and precipitation regimes). These results are also central in showing that even small ecosystems are important sources of biodiversity for the lower altitudes, stressing the urgency of including them within targeted monitoring and action plans to preserve their peculiar habitat, flora, and fauna.

- Abstract
The frontal thrusts and folds of the northern Apennines - Italy - are mainly covered under the alluvial deposits of the Po Plain. Some of these structures show geological evidence of Late Quaternary activity, thus posing the need for an accurate seismic hazard assessment due to widespread housing settlements, industries, lifeline infrastructures, and large towns. We present new morphostructural, geophysical, and seismological data to discuss the recent activity of the Broni-Sarmato fault, an 18 km-long outcropping section of the north-verging Stradella thrust, located 50 km south of Milan, along the Pede-Apennine thrust front (PTF) in the rear of the Emilia Arc thrust system. The new geoelectrical surveys across the fault scarp show deformation of the shallow deposits. The outcropping deformations, with a fault scarp ranging up to 25.8 m, are investigated within the seismotectonic framework of the PTF and the Emilia Arc. The analysis of the associated seismicity and new focal mechanisms highlight two seismogenic contractional volumes dipping at low-angle southwest-ward, at upper (<12 km) and lower crustal depths (~20–30 km). The shallow seismicity partially illuminates the Stradella thrust and its along-strike southeastward prosecution along the extent of the Stradella-Salsomaggiore Arc. Subordinately, it also illuminates some of the Emilia Arc thrust planes. The deeper seismogenic volume shows large patches of the basal thrust of the Emilia Arc fault system. We interpret the above multi-scale data as evidence of ongoing tectonic activity of the outer fronts of the Emilia Arc under a regional NNE-oriented compressional stress field, with some evidence of thrust involvement along the Pede-Apennine front. In our 3D fault-model reconstruction, all the analyzed thrust structures appear as expressions of a thick-skinned deformation that controls earthquake release at different structural levels.

- Abstract
The topography of orogenic belts responds to several contributions operating at short and long temporal and spatial (i.e., wavelengths) scales, from the surface to the deep mantle. Here, we aim to investigate the connection between morphometric characteristics, exhumation, and crustal deformation along and across the Italian Apennines, by comparing superficial with deeper data. Specifically, we present four sets of observations that are constructed by gathering previous data and adding new analyses and inferences, that include: (a) a new geomorphological set of analyses; (b) a database of available low temperature thermochronological cooling ages; (c) a reconstruction of drainage divide evolution in time and space based on the age of the youngest lacustrine deposits within each extensional basin; (d) Moho depth from receiver functions, gathering previous estimates and 13 new ones. From these sets of data, it emerges that across the main drainage divide of the Apennines, the morphological characteristics, the style of deformation and the spatial distribution of exhumation correlate with the geometries of the Moho and are associated with a strong asymmetry in the Northern-Apennines and a clear symmetry in the Central-Apennines. We interpret these results as evidence of a strong coupling between shallower and deeper geometries, that are most likely related to complex along-strike variations in the Apennines geodynamic setting.

- Abstract
The contribution aims to analyse the problematic relationship between material culture and ‘ethnic identity’, taking as a case study the pre-romans Italic peoples, with reference to those of central Apennine Italy. On a general methodological level, in fact, this relationship appears to be one of the most debated and problematised notions in archaeology, but also, at the same time, one of the most fundamental and common in the discipline itself. To overcome this contradiction, it has become increasingly common to circumvent a theoretical stance on the issue, thereby creating a large lacuna on a methodological level. The paper, on the contrary, wants to address this issue to fuel the debate, using as a case study a context, the preroman central Apennine Italy, in which a broad (material) cultural koiné corresponds, if we follow the Roman sources, to a rich mosaic of different peoples. The aim of the paper is therefore specifically to attempt, aware of the various stances in this long-running debate, to understand, motivate and qualify historically this cultural koiné, its partitions and the relationship it establishes with the peoples who express it.

[Methods]: Combining a set of environmental variables obtained at a fine scale (25-m resolution) from multi-year remote sensing imagery and field-collected vegetation data, we modelled the occurrence and cover of Juniperus communis-dominated dwarf shrubland, as well as its change over time, as a function of local climate, topography and land use, using linear and generalized mixed effects models. [Results]: Over a period of almost 60 years (1954–2012) shrubland occurrence increased by 12% and shrubland cover by 10% in our study sites. Its current distribution and change over time appear to be strongly shaped by the joint influences of fine-scale topography, above-ground biomass, land use and microclimate. Shrublands have been favoured locally in areas with harsher alpine environmental constraints and stronger resource limitations. [Conclusions]: Our study shows that in the Mediterranean high-mountain environment J. communis dwarf shrubland acts as a stress-tolerant pioneer vegetation, occurring in areas that are otherwise sparsely vegetated. Contrary to our expectations, at fine scales, warmer temperatures and the regional decline in grazing did not favour shrub encroachment. Despite increasing overall, J. communis shrubs have little competitive ability to successfully encroach grasslands, and remain restricted to less-productive areas. Our results confirm that fine-scale environmental heterogeneity can strongly influence shrub distribution and dynamics, thereby modulating future responses in evolving alpine ecosystems., Grant to the Department of Science Roma Tre University, Grant/Award Number: MIURItaly, Dipartimenti di Eccellenza,Articolo 1.

The frontal thrusts and folds of the northern Apennines - Italy - are mainly covered under the alluvial deposits of the Po Plain. Some of these structures show geological evidence of Late Quaternary activity, thus posing the need for an accurate seismic hazard assessment due to widespread housing settlements, industries, lifeline infrastructures, and large towns. We present new morphostructural, geophysical, and seismological data to discuss the recent activity of the Broni-Sarmato fault, an 18 km-long outcropping section of the north-verging Stradella thrust, located 50 km south of Milan, along the Pede-Apennine thrust front (PTF) in the rear of the Emilia Arc thrust system. The new geoelectrical surveys across the fault scarp show deformation of the shallow deposits. The outcropping deformations, with a fault scarp ranging up to 25.8 m, are investigated within the seismotectonic framework of the PTF and the Emilia Arc. The analysis of the associated seismicity and new focal mechanisms highlight two seismogenic contractional volumes dipping at low-angle southwest-ward, at upper (

The contribution aims to analyse the problematic relationship between material culture and ‘ethnic identity’, taking as a case study the pre-romans Italic peoples, with reference to those of central Apennine Italy. On a general methodological level, in fact, this relationship appears to be one of the most debated and problematised notions in archaeology, but also, at the same time, one of the most fundamental and common in the discipline itself. To overcome this contradiction, it has become increasingly common to circumvent a theoretical stance on the issue, thereby creating a large lacuna on a methodological level. The paper, on the contrary, wants to address this issue to fuel the debate, using as a case study a context, the preroman central Apennine Italy, in which a broad (material) cultural koiné corresponds, if we follow the Roman sources, to a rich mosaic of different peoples. The aim of the paper is therefore specifically to attempt, aware of the various stances in this long-running debate, to understand, motivate and qualify historically this cultural koiné, its partitions and the relationship it establishes with the peoples who express it.

Forest communities dominated by noble broad-leaved trees (maple, lime and ash) in Europe are of elevated scientific and conservation interest for the European Union. In this paper, we first present a synthesis of the maple and ash forests in peninsular Italy. By classifying these forests, we distinguish seven main groups for the territory, which only broadly match the syntaxa proposed in the literature. The variability of the Apennine data is then analysed floristically and phytogeographically (using chorological components) in a central-southern European context, using numerical classification, INSPAN, and direct ordination of several synoptic tables. These analyses allow us to identify six different groups of European Acer-Fraxinus communities. Canonical Variates Analysis (CVA) of the geographical components confirms the existence of distinct phytogeographical groups. In particular, we highlight the clear distinction between central European (including the Alps) and southern European coenoses. Among the latter there was a clear floristic and chorological distinction between Balkan and Apennine groups. These results reflect the biogeographical subdivisions of Europe, but do not support the syntaxonomical schemes proposed by other authors, which are based only on floristic-ecological information or (recently) use a smaller data set of Italian relevés. This study also shows that syntaxonomical schemes above the association level should pay more attention to phytogeographical aspects rather than focus on floristic-ecological information alone, in order to propose models that are of value on a geographical scale.

LAQUI-CORE was drilled in the co-seismic subsidence depocenter shown by DinSAR images in the Bazzano sub-basin after the 2009 Mw = 6.1 L'Aquila earthquake. LAQUI-CORE aimed at gathering high-resolution integrated stratigraphy and defining its relationships with the Paganica and other active faults that yielded co-seismic subsidence. Lithostratigraphy and micropaleontological analyses indicate a Late Pleistocene-Holocene fluvial-alluvial sequence, and below 41 m palustrine sediments sandwiching at 84–115 m a thick gravel package. Four 14 C ages gathered from 5 to 15 m yield calibrated ages between 6 and 41 ka BP. Paleomagnetism reveals a normal polarity above 84 m, while below the gravel package (115 m) it shows frequent polarity changes. The occurrence of intervals of clear reverse polarity testifies below 115 m the deposition during the Matuyama Chron. We conclude that the normal polarity package, down to 84 m along with the underlying gravels, were deposited at high sedimentation rate (0.46 mm/yr for the upper 15 m) during the Brunhes Chron (< 0.78 Ma), and lie over a much older Early Pleistocene palustrine sequence that we correlate with the well-known Madonna della Strada Synthem (1.2–1.7 Ma). We assume that the subsidence driving the deposition of the upper normal polarity sequence was due to the activity of the Paganica and neighbour faults during the Middle-Late Pleistocene. The lack of thick volcanostratigraphic markers, widespread in colluvial sediments from the L'Aquila plain older than 460 ka, suggests a normal-polarity sedimentation onset, thus a Paganica fault activity onset, around 400 ka. The 0.25 to 0.50 mm/yr subsidence at Bazzano extrapolated by DinSAR data and paleoseismological trenching at the Paganica fault is roughly consistent with the sedimentation rate (0.46 mm/yr) yielded by radiocarbon dating in the upper LAQUI-CORE. This implies that co-seismic subsidence in the Bazzano sub-basin during Late Pleistocene-Holocene times was mainly controlled by the Paganica fault activity. [ABSTRACT FROM AUTHOR]

- Abstract
Brown bears Ursus arctos were historically persecuted and almost eradicated from southern Europe in the twentieth century as a result of hunting and direct persecution. The effects of human-induced mortality were exacerbated by other threats, such as habitat loss and fragmentation, due to the expansion of human populations. As a result, nowadays there are only small fragmented populations of bears in southern Europe. Brown bears in the Cantabrian (north-western Spain), Apennine (central Italy), and Pindos (north-western Greece) mountains represent three examples of small and threatened bear populations in human-modified landscapes. Most of their range is characterized by high human densities, widespread agricultural activities, livestock raising and urban development, connected by dense networks of transport infrastructures. This has resulted in a reduction of continuous habitat suitable for the species. Here, we summarize the past and present histories and fates of these three populations as examples on how the coexistence of bears and people in human-modified landscapes can take different turns depending on human attitudes.

The late Miocene is a crucial interval for global climate evolution as well as for the regional geodynamic evolution of the Central Mediterranean area. It spans the transition from the warm Mid Miocene Climatic Optimum, associated with the major Monterey Carbon Isotope Excursion, to the cooler Pliocene, characterized by a bipolar glaciation. Within this climatic transition, during the early Tortonian, a positive carbon isotope excursion related to a global carbon cycle perturbation is recorded, named Carbon Maximum 7 (CM7). In this study, two upper Serravallian-lower Tortonian carbonate ramps of the Central Mediterranean have been analysed: the Latium-Abruzzi and the Apula ramps (Central Apennines, Central Italy). Carbon isotope ratios have been coupled with facies and microfacies analyses with the aims: (1) to identify the CM7 in the Central Mediterranean carbonate ramp successions; (2) to evaluate potential carbonate factory changes or demises related to the CM7; and (3) to discriminate the role of global vs regional factors in affecting the Mediterranean carbonate ramps. The two studied ramps show different evolutions due to regional geodynamics causes. The Latium-Abruzzi ramp drowns in the Tortonian, while the Apula shows a regressive trend, with upper Tortonian middle ramp facies overlying the lower Tortonian outer ramp. Despite the complex geodynamic setting, a positive carbon isotope shift has been identified in both ramps and correlated with the CM7. This positive carbon isotope shift may be linked to the strengthening of the global ocean circulation during the late Miocene cooling. This strengthening of the circulation enhanced the coastal upwelling, bringing nutrient-rich waters to the surface and triggering an enhanced primary productivity consistent with the CM7.

The E-vergent Northern Apennines formed by Oligocene-Miocene convergence and westward subduction of Adria beneath Europe. Extension ensued in the Mid-Late Miocene reflecting lower plate roll-back and causing opening of the back-arc Northern Tyrrhenian Sea. Post-orogenic extension is commonly advocated as the main driver of the exhumation of the belt's inner domain high-pressure/low-temperature (HP-LT) rock units. The Acquadolce Subunit of the Eastern Elba nappe stack contains HP-LT rocks recording peak blueschist conditions of 1.5–1.8GPa at 320°C–370°C loosely dated to the Oligocene-Early Miocene. It is sandwiched by two Late Miocene, out-of-sequence top-to-the E thrusts between Jurassic LP serpentinites on top and HT–LP contact metamorphosed marbles at its base. We document widespread W-verging ductile asymmetries within the Acquadolce Subunit, which correspond to top-to-the W extensional shearing for the nappe stack current orientation. This allowed for early syn-orogenic exhumation from blueschist- to greenschist-facies conditions, wherein coeval W-directed extension at the top of the exhuming units acted synchronously with E-directed thrusting at their base causing exhumation by extrusion in an overall contractional setting. The basal, E-vergent thrusting is, however, challenging to document as the wedge has since been reworked by Late Miocene, E-verging compressive tectonics, contact metamorphism, and later extension, obliterating much of the evidence supporting exhumation by extrusion during the early stages of wedge build-up. Syn-orogenic exhumation by extrusion from deep structural levels within the orogenic wedge is a viable mechanism to account for other exhumed HP-LT units in the inner part of the belt.

The Boiano Basin is one of the largest Quaternary intermontane basins of the central-southern Apennines within one of the most tectonically active areas of the Mediterranean region. In order to reconstruct its entire Quaternary stratigraphic, tec- tonic, and palaeoenvironment evolution, lithofacies and palaeomagnetic analyses have been performed on a 900 m-deep borehole (CP1) drilled in the southwestern sector of the basin. The Quaternary succession consists of an alternating of alluvial fan and fluvial-marshy deposits for a total thickness of 240 m, unconformably laying on Lower Miocene deposits of the Sannio Unit, thrusted on upper Miocene deposits of the Molise Flysch. In addition, the stratigraphic study and facies distribution of 29 intermediate and shallow wells drilled in the basin, allowing us to define the thick- ness and lithofacies variations of the Quaternary sedimentary units inside the entire Boiano Basin in the sector of Campochiaro alluvial fan. Our results demonstrate that the Boiano Basin infilling started during the late Early Pleistocene (c. 1.1 Ma) and developed with variation in lithofacies distribution and thickness. The first deposi- tional unit (Early Pleistocene-early Middle Pleistocene in age) was palustrine and fluvial-marshy, the second (Middle Pleistocene in age) was characterized by the occurrence of the first cycle of alluvial fan deposition, the third (late Middle Pleisto- cene in age) was newly palustrine and fluvial marshy and, finally, the fourth recorded two cycles of alluvial fan deposition (late Middle Pleistocene and Late Pleistocene in age, respectively), interspersed by short periods of palustrinity, tephra layers deposi- tion, and palaeosols development. The study allows the hypothesizing that the Qua- ternary infilling was accommodated within a graben (or semigraben) structure, affected mainly by extensional fault systems localized in the inner part of the basin and secondly by fault systems bounding the basin.

In this work, the crustal volume struck by the 2016–2017 seismic sequence in Central and Northern Apennines is investigated using constrained 3-D inversion of the gravity anomalies. In order to focus on the area comprising the two mainshocks of the sequence, we perform a regional field removal on the data as a preprocessing step. This residual data set is then inverted into a 3-D density contrast model. We perform a series of inversions to test different geological scenarios and parameters, with increasing complexity in the reference geometries. We first test a model comprising turbidites, carbonates and evaporites, and basement and then introduce a low-density layer at the top of the basement. The geometries are obtained in agreement with the available geological and geophysical information in the area. We found that the density distribution with depth is compatible with previous models. Moreover, results support the hypothesis based on borehole evidence of a low-density upper basement across the entire area, possibly consisting of low-grade metamorphic rocks (phyllites). Finally, we compare our modeling results to the spatial distribution at depth of major seismic events between August and November 2016. These events appear to be concentrated within the denser units at both shallow and deep locations, while the deeper events often occur in a region of major density contrast corresponding to the top of the basement.

Abstract: The Central portion of the Western Periadriatic Basin is a foreland basins systems associated to the Central Apennine Outer Orogenic Wedge that stretches along the Marche and Abruzzi regions of Italy; an area that has been studied since long time and where a plenty of surface and subsurface data are available. The present study is aimed to review and synthetize these data, add new surface and subsurface data in order to define a firm stratigraphic and tectonic framework that is base for the reconstruction of the Pliocene-Pleistocene tectonic-stratigraphic evolution of the Central portion of the Western Periadriatic Basin. The study integrates field mapping, published geological maps, seismic lines, well logs and an updated chronostratigraphic scheme. Six major NNE-SSW thrust stacks and eight unconformity bounded stratigraphic units have been defined; then, a NE-SW oriented zone separates a northern from a southern sector which have differences in structural styles, amount of shortening, basins'' widths and thicknesses of stratigraphic units. Despite these differences, the deformation timing, the depositional history and the migration of basins system are common in both sectors and eight tectonic-stratigraphic evolutionary stages have been reconstructed with sequential restoration of two representative cross-sections. The results highlight that the Pliocene-Pleistocene stratigraphic and tectonic evolution of the Central Western Periadriatic Basin preserves the records of supra-regional and global controls which drive thrust propagation, orogen growth, basins'' migration and basins'' sedimentary infill. In particular, the stratigraphy preserves global third-order eustatic/climatic changes that have a strict feed-back and concomitance with tectonic pulses. The latter are regulated 1) by cyclic growth of an orogenic wedge undergoing coeval erosion and sedimentation and 2) by eastward retreat of a westward subducting and flexing continental lithosphere.

VOLCANIC hazard analysis , *VOLCANIC eruptions , *HAZARD signs - Abstract
Volcaniclastic debris flows are dangerous natural phenomena that originate in volcanic areas not only during or shortly after an eruption but also during a period of volcanic quiescence, when heavy and/or persistent rains remobilize unconsolidated pyroclastic deposits. In Italy, one of the areas most affected by these phenomena is that of the Apennine Mountains which border the southern Campania Plain surrounding the Vesuvius volcano. Historical accounts record in these areas that more than 500 debris flow events occurred during the last five centuries. These events caused very dangerous consequences such as loss of life and serious damage to property. An example is the devastating event of Sarno of 5 May 1998 which caused the death of more than 150 people and considerable damage to villages located at the foot of the Apennine Hills. In order to contribute to the assessment and mitigation of the debris flow risk, we propose a zonation map that identifies the areas more prone to generation and invasion by volcaniclastic flows. This map is based on field investigations and morphometric analyses derived from a digital elevation model with spatial resolution of 10 meters. [ABSTRACT FROM AUTHOR]

- Abstract
The lunar Apennines, located in the southeast of Mare Imbrium, is the largest range on the Moon. The gravity anomalies on profiles across the mountains reveal evidence of a great fault zone characteristic. The deep crustal structures of lunar Apennines are analyzed on the basis of topographic data from Chang’E-1 satellite and gravity data from Lunar Prospector. The inverted crust-mantle models indicate the presence of a lithosphere fault beneath the mountains. Inverted results of gravity and the hypothesis of lunar thermal evolution suggest that the lunar lithosphere might be broken ∼3.85 Ga ago due to a certain dynamic lateral movement and compression of lunar lithosphere. This event is associated with the history of magma filling and lithosphere deformation in the mountain zone and adjacent area. Moreover, the formation and evolution of Imbrium basin impose this effect on the process. [ABSTRACT FROM AUTHOR]

Abstract: In Pennsylvania, the Taconic Orogeny lasted from ∼461 to ∼443Ma as Cambro-Ordovician slope deposits were deformed into mountains edging the Laurentian craton at the same time that materials from an adjacent deep-water basin were being transported ∼50 –70km across a carbonate platform into foreland basins. This paper focuses on shelf-edge hinterland features, mostly the Martic Zone as a folded, stack of imbricate thrust sheets of slope materials that corresponds to Vermont''s Taconic Mountains and Southern Quebec''s zone of Taconic allochthons. Work of the last century is summarized, corrected, and combined with a new ∼450Ma radiometric date and fluid inclusion data from the Pequea Mine within the Martic Zone. These and abundant new graptolite and conodont dates in the foreland paint a revised Pennsylvania picture differing from the northern Taconic areas. Differences are: (1) transport of very large allochthonous masses of deep-water material, the Dauphin Formation, far across the carbonate platform, and (2) deformation migrating progressively across that platform during a ∼15 –20m.y. period, incorporating it and its foreland cover into alpine-scale, recumbent folds and thrusts. The scenario has many analogies to Italy''s modern Apennine Mountains minus the Latian volcanics. [Copyright &y& Elsevier]

ITALIAN pottery , *MOTOR ability , *TECHNOLOGY transfer , *ARTISANS , *MEMORY - Abstract
In this paper, I suggest that studies of motor development, learning and memory may provide important insights into technological change and conservatism in prehistoric craft activities. The physical and mental processes involved in the learning and development of highly skilled motor activities result in strongly rooted changes in an individual's actions and levels of performance. In terms of craft production, this means that mature, skilled artisans have a selective and efficient array of actions and strategies, which they can draw upon to produce competent products of predictable quality and quantity. The reverse of this degree of specialized physical training is, however, the possibility of 'negative transfer' when it comes to learning new skills. The presence within the late second millennium bc in Italy of both handmade and wheelmade pottery technologies can be explained in part by the degree of difficulty mature craftspeople may have experienced in learning the radically different physical processes involved in wheel-manufacture.

A detailed 24-h investigation in August 2005 evaluated net dissolved and particulate nutrient budgets in a small trout farm located in the Parma Apennines. During the monitoring period, due to water shortage, the Cedra Creek was almost entirely diverted into the farm; the water flow was 190 l s-1, and the fish standing stock about 20 t. Inflow and outflow waters were characterized for dissolved gases (O2 and CO2) and dissolved and particulate inorganic nutrients ([image omitted] , [image omitted] , [image omitted] , [image omitted] , PN, and PP). Solute concentrations in outflowing waters were found to fluctuate considerably during the day, due to fish metabolic activity and farm-management practices. Despite the small amount of feed supplied to the fish (75 kg d-1) due to high water temperatures (∼20 °C) and the high feed conversion factor (∼1.2), the farm released net amounts of 2.20 and 0.76 kg d-1 of nitrogen and phosphorus, respectively, to the Cedra Creek. Of the nutrients produced, 68% of the nitrogen was as [image omitted] , while 67% of the phosphorus was particulate. Significantly different [image omitted] , [image omitted] , and PP concentrations were measured 500 m downstream of the fish farm compared with inflowing water. This study supports the hypothesis that the ecological quality of creeks or streams receiving fish farm effluents can be seriously affected due to fine particle sedimentation, interstice clogging, simplification of benthic macrofauna communities, and stimulation of microfitobenthos growth.

We present high-resolution elastic models and relocated seismicity of a very active segment of the Apennines normal faulting system, computed via transdimensional local earthquake tomography (trans-D LET). Trans-D LET, a fully nonlinear approach to seismic tomography, robustly constrains high-velocity anomalies and inversions of P wave velocity, i.e., decreases of VP with depth, without introducing bias due to, e.g., a starting model, and giving the possibility to investigate the relation between fault structure, seismicity, and fluids. Changes in seismicity rate and recurring seismic swarms are frequent in the Apennines extensional belt. Deep fluids, upwelling from the delaminating continental lithosphere, are thought to be responsible for seismicity clustering in the upper crust and lubrication of normal faults during swarms and large earthquakes. We focus on the tectonic role played by the Alto Tiberina low-angle normal fault (ATF), finding displacements across the fault consistent with long-term accommodation of deformation. Our results show that recent seismic swarms affecting the area occur within a 3km thick, high VP/VS, densely cracked, and overpressurized evaporitic layer, composed of dolostones and anhydrites. A persistent low VP, low VP/VS volume, present on top of and along the ATF low-angle detachment, traces the location of mantle-derived CO2, the upward flux of which contributes to cracking within the evaporitic layer.

We document that the undifferentiated chaotic Ligurian Units of the Monferrato–Torino Hill sector (MO-TH) at the Alps–Apennines junction consist of three different units that are comparable with the Cassio, Caio and Sporno Units of the External Ligurian Units of the Northern Apennines. Their internal stratigraphy reflects the character of units deposited in an ocean–continent transition (OCT) zone between the northwestern termination of the Ligurian–Piedmont oceanic basin and the thinned passive margin of Adria microcontinent. The inherited wedge-shaped architecture of this OCT, which gradually closed toward the north in the present-day Canavese Zone, controlled the Late Cretaceous–early Eocene flysch deposition at the trench of the External Ligurian accretionary wedge during the oblique subduction. This favoured the formation of an accretionary wedge increasing in thickness and elevation toward the SE, from the MO-TH to the Emilia Northern Apennines. Our results therefore provide significant information on both the palaeogeographical reconstruction of the northwestern termination of the Ligurian–Piedmont oceanic basin and the role played by inherited along-strike variations (stratigraphy, structural architecture and morphology) of OCT zones in controlling subduction–accretionary processes. Supplementary material: A spreadsheet with X-ray fluorescence spectrometry and inductively coupled plasma mass spectrometry whole-rock major and trace element composition of mantle peridotites, and photomicrographs of mantle peridotites are available at https://doi.org/10.6084/m9.figshare.c.4519643

Question: Do topographic factors that determine the distribution pattern of sub-Mediterranean coppiced woods influence the functional structure of their herb layer? Study area: Umbria-Marche Apennines (Italy). Methods: In 156 plots we collected topographic data and species cover. We identified the main forest communities using a Multivariate Regression Tree (MRT) analysis on the relevés by species matrix constrained by altitude, aspect and slope angle. For the herb layer of each plot, we calculated the community-weighted mean trait values (CWMs) and functional diversity (FD) indices. We compared CWM and FD values between MRT groups at each partition of the tree graph and checked linear trends of CWMs and FD indices along gradients illustrated by topographic variables and mean Ellenberg’s Indicator Values. Results: Altitude and aspect segregated the main forest types and filtered the herb layer functional structure, depending on the considered traits. We observed a shift from strategies related to cold stress and the shortness and unpredictability of growing season at the highest altitudes and on north-facing slopes, to those related to dryness at lower elevations and on south-facing slopes. Environmental filtering changed the relative abundance of traits between mountain and hilly woods, as well as functional richness of life form, vegetative propagation, pollen/spore vector, and functional evenness, divergence, and Rao’s quadratic entropy of storage organs types. Within hilly forests, functional divergence increased toward north-facing slopes, while evenness increased toward south-facing slopes. Conclusions: Altitude and aspect, besides shaping the distribution patterns of sub-Mediterranean coppiced woods, influence the functional structure of their herb layer in a different manner. In mountain woods, higher altitude fosters convergence of the storage organs more suitable to tolerate cold stress. In hilly woods, drought and the heterogeneous distribution of resources on south-facing slopes increase functional evenness, whereas the higher availability of resources on north-facing slopes promotes divergence.

The census of the loci classici of 1,227 native, non-endemic vascular plants described from Italy is here presented and described. The effective place of publication of accepted names, basionyms and homotypic synonyms were identified and critically verified. The geographic information on the loci classici was excerpted from the protologues, as well as information on typification for the taxa described before 1 January 1958. The names without a holotype are 1,165. For 591 names a lecto- or neo-typification is available in literature, while 572 currently accepted taxa still need a type designation. For ten of these names showing previous ineffective typification, nomenclatural types are designated here ( Allium savii , A. tenuiflorum , Anemone millefoliata , Catapodium tuberculosum , Cynosurus siculus , Filago congesta , Saponaria bellidifolia , Sclerochloa patens , S. zwierleinii , and Vicia leucantha ). A new combination ( Trisetaria aurea comb. nov. ) is proposed. The general picture of the currently accepted taxa of vascular plants described from Italy, including endemics, amounts to 2,631, i.e. about 32% of the native flora currently recorded for the country.

The recharge of an aquifer is fundamental to evaluate the availability of the resource and for planning its use over the time. In general, indirect methods are widely used, because these are based on the rainfall, evapotranspiration and runoff data. These three parameters are not always simple to evaluate in relation to the possible presence of errors in the available data, malfunction of instruments or difficulty to make a monitoring in relation to the complexity of the area, with consequent uncertainty on the results. In such situations, the use of a direct method could be useful to estimate more accurately the aquifer recharge. A common direct method is based on the analysis of the spring hydrographs, i.e. the discharge monitored at the spring. In this work, a spring hydrograph from the central Apennines of Italy has been analysed in order to estimate the average recharge value feeding the aquifer.

Aim of this study was to investigate the presence and distribution of Hydraenidae in relation to selected abiotic parameters in a single, uniform riffle of the Caramagna Stream (northwestern Italy). Six species belonging to the genus of Hydraena Kugelann, 1794 were found (H. andreinii D'Orchymont, 1934, H. subimpressa Rey, 1885, H. assimilis Rey, 1885, H. heterogyna Bedel, 1898, H. truncata Rey, 1884 and H. devillei Ganglbauer, 1901), with evident niche preferences. Our study provided interesting information about ecological requirements of minute moss beetles at small-scale and evidenced that maintaining elevate habitat diversity is essential to preserve high species abundance at local scale.

We analyze the source-to-sink variations of in situ 10Be, 26Al and 21Ne concentrations in modern sediment of the Po river catchment, from Alpine, Apennine, floodplain, and delta samples, in order to investigate how the cosmogenic record of orogenic erosion is transmitted across a fast-subsiding foreland basin. The in situ 10Be concentrations in the analyzed samples range from ∼ 0.8 × 10 4 at / g QTZ to ∼ 6.5 × 10 4 at / g QTZ . The 10Be-derived denudation rates range from 0.1 to 1.5 mm/yr in the Alpine source areas and from 0.3 to 0.5 mm/yr in the Apenninic source areas. The highest 10Be-derived denudation rates are found in the western Central Alps (1.5 mm/yr). From these data, we constrain a sediment flux leaving the Alpine and the Apenninic source areas (>27 Mt/yr and ca. 5 Mt/yr, respectively) that is notably higher than the estimates of sediment export provided by gauging (∼10 Mt/yr at the Po delta). We observe a high variability in 10Be concentrations and 10Be-derived denudation rates in the source areas. In the Po Plain, little variability is observed, and at the same time, the area-weighed 10Be concentration of ( 2.29 ± 1.57 ) × 10 4 at / g QTZ (±1 SD of the dataset) from both the Alps and the Apennines is poorly modified (by tributary input) in sediment of the Po Plain ( ( 2.68 ± 0.78 , ± 1 SD ) × 10 4 at / g QTZ ). The buffering effect of the Po floodplain largely removes scatter in 10Be signals. We test for several potential perturbations of the cosmogenic nuclide record during source to sink transfer in the Po basin. We find that sediment trapping in deep glacial lakes or behind dams does not significantly change the 10Be-mountain record. For example, similar 10Be concentrations are measured upstream and downstream of the postglacial Lake Maggiore, suggesting that denudation rates prior to lake formation were similar to today's. On the scale of the entire basin, the 10Be concentration of basins with major dams is similar to those without major dams. A potential modification of the 10Be-mountain record during sediment storage in the subsiding Po Plain can be excluded as measured 26Al/10Be ratios do not show the addition of deeply buried material. A barely resolvable excess 21Ne signal in the Po plain indicates recycling of previously eroded sediment rather than accumulation of cosmogenic nuclides during surficial floodplain transport. Our results demonstrate that the cosmogenic record of mountain erosion is effectively transmitted from the source areas to the sediment sink, even across a strongly subsiding foreland basin. We show that this record is poorly influenced by a range of potential geological and anthropogenic sources of bias, and is largely independent from upstream sediment interception and sediment storage in the floodplain.

Geochemical maps can provide us with much information on geology, earth surface processes and anthropogenic pressure and are valuable tools for ore prospecting and land management. Stream sediments represent an integral of the various possible sources of sediments upstream from the sampling point therefore there can be multiple signal sources but generally the prevailing signal source is the one related to bedrock geology. Stream sediments collected from active second-order channels including singular geological units, were selected in order to determine the geochemical characteristics of each unit. The aim of this study was to analyse their potential for using them to integrate geological interpretation and produce a geologically-oriented geochemical map. From the 770 samples collected for a regional geochemical mapping program, we selected 149 samples whose catchment basin included only one of the members recognized within the Marnoso–Arenacea formation. This Middle-Upper Miocene (Langhian–Tortonian) turbiditic unit forms the backbone of the Romagna Apennines and has been subdivided into 14 members according to age and lithostratigraphic criteria. The results indicate that there are marked differences in the composition of the members of the Marnoso Arenecea formation which indicate the provenance of the sediment and the palaeogeographic evolution of the units. By means of univariate and multivariate statistical analyses (Factor analyses) two main types of sediment compositions are identified: Tortonian members are characterized by sialic coarse grain- sediments while the Langhian–Serravallian members are richer in carbonate fraction, slightly enriched in a mafic contribution. This study elaborated the geochemical data from a geological point of view by integrating the information available in literature to spatially extend the interpretation based on limited site observation as for petrographic studies. In general, the geochemical map based on a geological unit could be a useful tool for carrying out the geological reconstruction of a complex area.

The present work is aimed at studying several Asperula (Rubiaceae) sect. Cynanchicae populations in southern Apennines, Italy, with particular reference to those referred to A. calabra, by employing biometrical methods on macromorphological data. Among other historical misapplications, A. cynanchica subsp. cynanchica seems to be very rare or missing in southern Italy. The enigmatic Asperula calabra, confirmed to be limited to a single mountain population in Calabria, appears to be strictly related to A. aristata subsp. scabra, so we suggest to treat it as a further subspecies of A. aristata. This latter species is otherwise distributed throughout southern Italy with subsp. scabra and subsp. aristata, characterised by slight morphological differences, which are correlated to altitudinal ranges.
