- Abstract
EUSeaMap 2021 is the fifth iteration of EUSeaMap. All versions have been produced as part of the EMODnet Seabed Habitats project, which is one of several thematic lots in EMODnet. The project has brought together a European consortium of specialists in benthic ecology and seabed habitat mapping. The partners first collaborated in EMODnet phase 1 (2009-2012) to deliver a prototype predictive seabed habitat map in four trial basins (Greater North Sea, Celtic Seas, Baltic, Western Mediterranean). This predictive model was named EUSeaMap (Cameron and Askew, 2011). In EMODnet Phase 2 (2012-2016), the consortium extended EUSeaMap coverage to all European regions (Populus et al, 2017). In phase 3 (2017-2021), a first version (2019) extended the spatial coverage further North in order to include the Barents Sea, developed better environmental data were incorporated, and dramatically improved the spatial detail. The new version, developed in the period 2019-2021 and named 2021, is substantially evolved from the previous version as it accounts for new seabed substrate data published by EMODnet Geology in 2021, including in Denmark, Estonia, France, Ireland, Italy, Latvia, Norway and Spain, 2) is published in new classifications, including the new version of the marine section of EUNIS, named EUNIS 2019 and 3) addresses some issues identified in EUSeaMap 2019.

- Abstract
The need for maps of the seabed has become increasingly urgent in recent years for a wide range of reasons and uses, including reporting on the state of the marine environment to implement EU policies such as the MSFD. In ten years, the EMODnet Seabed Habitats initiative has produced maps for all European marine regions, where input data allowed, the resultant seabed habitat maps are known collectively as ”EUSeaMap”. With products such as EUSeaMap, it is assumed that mapping the broad habitat types defined in seabed habitat classifications (e.g. EUNIS) provides appropriate proxies for the occurrence of the species or communities of species that occupy them. In addition to being released in EUNIS 2007-2011 and the MSFD Broad Benthic Habitat Types, the next version of EUSeaMap (expected in September 2021) will be released in three classifications, namely EUNIS 2019 (the new version of EUNIS), and the regional classifications HELCOM HUB and the Mediterranean habitat types. This report proposes crosswalks between EUSeaMap modelled broad habitat types and the three classifications, and briefly discusses the opportunities/challenges entailed by the crosswalks. Our conclusion is that no major issue is expected for the translation of EUSeaMap into these classifications. We also argue that in EUNIS 2019 there are gaps at biotope levels, particularly in the Black Sea and the Arctic, and that measures should be taken to address these gaps.

- Abstract
Since its inception, in 2009, EMODnet Seabed Habitats has brought together a European consortium of specialists in benthic ecology and seabed habitat mapping to develop a transnational broad-scale seabed habitat map, named EUSeaMap. EUSeaMap is the only pan-European cartographic product that provides a standardised trans-boundary overview of the spatial distribution of seabed habitats across Europe. As such, it has been extensively used in various applications such as Marine Protected Area evaluation or cumulative impact of stressors on habitats, and it is likely to be used again in the future in various marine ecosystem assessments. It is therefore important to continue to update it regularly when significant improvements to the data products that constitute its basis, i.e. the seabed substrate, bathymetry or environmental variables, are published. In addition to EUSeaMap, it would be desirable to provide stakeholders with products on the spatial distribution of targeted habitats/biotopes such as those of conservation interest (e.g. kelp forest, seagrass meadows, coral reefs). Some techniques, hereafter referred to as "SDMs", are acknowledged to be effective in mapping these habitats. We argue that a program that would use these techniques to map these key habitats/biotopes in European waters would be invaluable, but such a program can only be achieved if there is a significant improvement in the spatial resolution of environmental variables. An important message of this report is therefore that the EU should consider funding a project that would develop spatially explicit high-resolution (at least 500 m) data products on key variables (light availability, hydrodynamics, wave exposure, temperature, oxygenation, chlorophyll-a, phosphate, nitrate, etc.) that would spatially cover all European waters.

A substantial revision of the map creation process has also been carried out in order to make it more reproducible. This document describes all these modifications which have led to the elaboration of EUSeaMap 2019.

- Abstract
In order to most benefit from the potential offered by the European marine basins in terms of growth and employment (Blue Growth), and to protect the marine environment, we need to know more about the seafloor. European Directives, such as the MSFD, but also the Horizon 2020 roadmap explicitly called for a multi-resolution full coverage of all European seas including bathymetry, geology and habitats. The present work, following on a suite of past initiatives, has made a big step forward in this direction. It has first boosted the collation of existing maps from surveys by setting up a framework and a procedure to encourage people to submit their maps and data. This resulted in a more attractive EMODnet seabed habitat portal and a snowball effect with more and more people willing to join. However, collation will eventually come to an end and as new creations of seabed habitat maps are so complex and time-consuming, a cost-efficient way to meet the need for a full-coverage habitat map was found to be low-resolution maps and models to predict seafloor habitat types. The broad-scale map referred to as EUSeaMap has been created by this project and after the first two phases it now covers all European basins from the Barents Sea to Macaronesia and to the Black Sea. By harmonising mapping procedures - based on the EUNIS classification - and fostering a common understanding among seabed mappers in Europe, EUSeaMap provides today the community with a comprehensive, free and ready-to-use map that can find applications at regional scale for management and conservation issues. Tables and maps for all basins can be found in section 3 “Results and disciussions”. The project has played a key role in giving feedback to other EMODnet communities dealing with bathymetry, geology and biology, all essential data sources for the broad-scale map. It has also improved the understanding of the EUNIS habitat classification - with a focus on the Adriatic and the Black Sea - by better specifying transitions between classes based on benthic ground-truth data. It has fostered the development of oceanographic variables such as light, waves and currents that have a strong bearing on habitats. Finally it has also been instrumental in developing map confidence assessment methods that account for the broad spatial variation in data sources quality and for uncertain boundaries between habitat classes. The EUSeaMap methods are repeatable and ensure that the predictive maps can continue to be improved in the future, as a result either of EUNIS enhancements or increase in resolution. From today’s 250m resolution it is likely that new deliveries of enhanced source layers due to steady progress in oceanography and geophysics will enable constant refinement of the maps over time.

TEMPERATURE ,MARINE biology ,PHYSIOLOGY - Abstract
Photoperiod variations are the principal environmental signals entraining circannual activity in mammals, which is also believed to be influenced by changes in temperature and nutrition. Control of the moltin phocids has not been extensively studied with experimental manipulations of environmental factors, but substantial work indicates thatphotoperiod has a primary influence on mammalian breeding and furring mechanisms. Studies were undertaken to reestablish the molt cycle in five harbor seals (Phoca vitulina) previously kept in an enclosed facility with a limited air/water temperature gradient and artificial photoperiod. The seals were exposed to an extended temperature gradient during the first period of study, and no molting was observed. Thesecond period of study was characterized by a natural occurring photoperiod of 8 h 53 min light (L)/15 h 07 min dark (D) and a maximal 15h 31 min L/8h 29 min D duration, and molting occurred in all individuals. These results suggest a prevalent influence of photoperiod variation on the harbor seal molt. [ABSTRACT FROM AUTHOR]

- Abstract
Disentangling the impact of Late Quaternary climate change from human activities can have crucial implications on the conservation of endangered species. We investigated the population genetics and demography of the Mediterranean monk seal ( Monachus monachus ), one of the world's most endangered marine mammals, through an unprecedented dataset encompassing historical (extinct) and extant populations from the eastern North Atlantic to the entire Mediterranean Basin. We show that Cabo Blanco (Western Sahara/Mauritania), Madeira, Western Mediterranean (historical range) and Eastern Mediterranean regions segregate into four populations. This structure is probably the consequence of recent drift, combined with long-term isolation by distance ( R
2 = 0.7), resulting from prevailing short-distance (less than 500 km) and infrequent long-distance dispersal (less than 1500 km). All populations (Madeira especially), show high levels of inbreeding and low levels of genetic diversity, seemingly declining since historical time, but surprisingly not being impacted by the 1997 massive die-off in Cabo Blanco. Approximate Bayesian Computation analyses support scenarios combining local extinctions and a major effective population size decline in all populations during Antiquity. Our results suggest that the early densification of human populations around the Mediterranean Basin coupled with the development of seafaring techniques were the main drivers of the decline of Mediterranean monk seals.- Published

- Abstract
This study analyzes morphometrically 17 skulls of the Mediterranean monk seal Monachus monachus housed in different Italian Museums and collections. We considered several morphometric variables (31 linear, 1 volumetric and 1 surface area measurements). In addition, we identified, measured and compared two nonmorphometric variables, namely, the bone densities of selected areas obtained using a dual-energy X-ray absorptiometry (DXA) device. The high correlation coefficient of all variables indicated continuous growth with the onset of age. The ranking of the hierarchical cluster analysis identified the presence of three main groups containing individuals of similar sizes: lactating pups and yearlings; subadult individuals and adult females; and adult males. Smaller groups were identified within these clusters, and their respective allocations into two subgroups were argued on the basis of skull development and other factors. The discriminant analysis of the three main groups indicated a discriminant diagnostic key, based on condilobasilar length (CBlr-L); maximum mandibular branch height (MB-H); and surface area of the bulla tympanica. The proposed diagnostic key is useful to classify monk seal skulls of unidentified age and sex. The data reported here suggest that in this species certain adult skull growth features (enhanced tympanic bullae surface area extension, occipital bone density) are sexually dimorphic and possibly related to specific anatomical functions. These functions may include an enhanced auditory capacity; an increased development of the cranial musculature capable of supporting a large skull and guaranteeing the mandibular strength necessary for mastication; and male to male social interactions.
