Abstract

Barn owls are the most widely distributed group of owls in the world and are among the most common accumulators of small vertebrate remains at archeological and paleontological sites. Despite its importance as a bone remains accumulator and predictor of paleoenvironmental conditions due to its generalist habits, the vertebrate prey of this raptor has been scarcely studied from an ecological community perspective, especially considering the diverse range of prey it captures. Archeological, paleontological, and taphonomic studies typically reveal taxon-specific patterns, focusing primarily on small rodents. In order to overcome this problem, we studied an assemblage of vertebrate bones from barn owl pellets in the central Monte Desert of Argentina. Our analysis included the full range of prey taxa, including rodents, marsupials, birds, and reptiles, addressed from both an ecological and neo-taphonomic perspective. We compare the taxonomic and taphonomic findings with those from regional small vertebrate records obtained from various sampling types over the past 50 years to explore recent environmental changes within the Anthropocene. The assemblage of small vertebrate prey presented here comprises five species of cricetids, one species from the Caviidae family, and at least one ctenomyid rodent species. Additionally, the assemblage includes one species of didelphid marsupial, one reptile species, and at least six passeriform bird species that belong to separate families. The overall taphonomic trends are consistent with the typical barn owl pattern. However, our analysis identified a larger percentage of postcranial elements exhibiting signs of digestion compared to pellet-derived vertebrate bone assemblages previously documented. Furthermore, it is important to note that a significant proportion of avian bone fragments exhibit distinct signs of digestion. [ABSTRACT FROM AUTHOR]

Abstract

The genus Ctenomys of subterranean rodents is one of the most species-rich genera of Mammalia, with 66 living species currently recognized. However, the taxonomy of the genus is dynamic with several new species and new synonymies proposed during the last decade. One of the species groups that have undergone more changes in contents in the last years is the Ctenomys mendocinus species group. Here, based on phylogenetic analysis of mitochondrial DNA sequences and qualitative and quantitative morphological evidence, we conducted an appraisal of the species richness of tuco-tucos of the C. mendocinus species group, describing two new species from west-central Argentina. The new taxa are morphometrically distinctive when compared with other geographically or phylogenetically close species of the genus, showing qualitative differences in their craniodental anatomy. One of the new species is known from the eastern Andean slopes of La Rioja and San Juan provinces, occurring on montane grasslands and shrublands above 3,500 m a.s.l., while the other is endemic of southwestern Mendoza province, occurring on montane grasslands and shrublands between 2,400–2,700 m a.s.l. In addition, we include for the first time the nominal forms C. fochi and C. validus in a phylogenetic analysis of the genus Ctenomys, showing that both correspond to the C. mendocinus species group, being the second a junior synonym of C. mendocinus. Finally, we made some comments about other candidate species within this species group as well as highlight issues that need to be addressed to gain a robust picture of the specific richness of Ctenomys.

Abstract

Salinomys delicatus Braun & Mares, 1995 is a sigmodontine rodent endemic to perisaline environments in west-central Argentina. It is currently considered to be a Vulnerable species due to its patchy distribution and the loss of optimal habitats caused by intensive anthropogenic activities. In this work, we document the first record for this species in the Dry Chaco ecoregion of northwestern Córdoba province (Argentina), enlarging the geographic distribution of this species by approximately 115 km to the east of previously known occurrences. Our new record highlights the need to strengthen conservation policies in the Dry Chaco of Córdoba province.

Abstract

The genus Andalgalomys Williams and Mares, 1978 includes three species of small phyllotine rodents: Andalgalomys olrogi Williams and Mares, 1978; Andalgalomys pearsoni (Myers, 1977); and Andalgalomys roigi Mares and Braun, 1996. These mice are distributed from southeastern Bolivia and western Paraguay to west-central Argentina, occupying mostly semi-desert environments, such as the Dry Chaco and High Monte. Available phylogenetic analysis of DNA sequences suggests that Andalgalomys olrogi and Andalgalomys roigi, which also share the same diploid complement, constitute the same species. We tested this hypothesis through a qualitative and quantitative morphological approach, in order to integrate different lines of evidence. Based on the largest sample analyzed to date, we found that some of the supposedly diagnostic traits of both Andalgalomys olrogi and Andalgalomys roigi (e.g., dorsal coloration) are more variable than previously documented. In addition, principal component analysis failed to separate Andalgalomys olrogi from Andalgalomys roigi in the multivariate space, although clearly segregate Andalgalomys pearsoni from these two taxa. Based on these findings, plus previous evidence, we consider Andalgalomys roigi as a junior synonym of Andalgalomys olrogi. [ABSTRACT FROM AUTHOR]

Un paseo por occidente de la PayuniaSiguiendo nuestro viaje desde el Vn. Domuyo (Figura1), retornamos hacia Chos Malal y a unos 8 km hacia elNE por la RN 40, en La Salada, tomamos la RP 2 (luegoRP 37) hacia el norte y llegamos a la Reserva ProvincialTromen, en donde dos colosales volcanes, casi gemelos,el Tromen y el Wayle, enmarcan una laguna creandoun paisaje único. Seguimos hacia el norte, para tomarnuevamente la RN 40 y cruzando el Río Barrancas, unode los afluentes del Colorado, ingresamos nuevamentea Mendoza.A la altura de la Pasarela nos introducimos nuevamenteen la Reserva La Payunia, cruzando escoriales de basaltoen campos de arena. Llegamos así por el oeste a losVolcanes Payún Matru (3715 m) y Payún Liso (3838 m). Asus pies, los yardangs (formaciones de rocas ignimbritasmoldeadas por el viento) le dan un toque distintivo alpaisaje. En el Payún Matrú, como en los otros lugaresdonde hemos realizado muestreos, podemos apreciardos de pisos altitudinales de vegetación, entre el másalto por encima de 2800 m y el que se encuentra en labase a menos de 2200 m. Del Payún Matrú vamos haciael norte al Cerro Fortunoso y donde está uno de loscentros de YPF. Es conveniente preguntar allí cómo ir aLos Ramblones y llegar a la RP 186. En este recorridoiremos por la vertiente oriental de la Sierra de Palauco,en donde encontraremos algunos cursos de agua. Fil: Roig, Sergio Alberto.

Abstract

Esta contribución es un homenaje a José Yepes por los 75 años transcurridos desde que describiera el género Tympanoctomys, y por los 90 años de su ingreso al Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”. Las ratas vizcacha son el epítome de roedores sudamericanos adaptados al desierto, y han constituido un verdadero modelo, no solo por presentar distintos atributos especializados para la vida en ambientes xéricos, sino también como uno de los mamíferos con mayor número cromosómico. En este capítulo brindamos un panorama global sobre el estado del conocimiento del género y las especies relacionadas, en áreas como, distribución, ecología, genética y conservación. Las perspectivas se enfocan sobre los vacíos y preguntas en temas aún no resueltos y que constituyen líneas fascinantes y promisorias para investigar y profundizar. This contribution is a tribute to José Yepes on the 75th anniversary of his description of the genus Tympanoctomys, and the 90th anniversary of his admission to the Argentine Museum of Natural Sciences “Bernardino Rivadavia”. Viscacha rats are the epitome of South American rodents adapted to desert habitats, and are a true model, not only to present different specialized attributes for life in xeric environments, but also as one of the mammals with the highest chromosomal number. In this chapter, we present an overview of the state of knowledge of the genus and related species, regarding aspects such as distribution, ecology, genetic and conservation. Perspectives focus on gaps and unresolved issues that are fascinating and promising research lines.
