Biogeographic patterns of the bats of Argentina: species richness and distributional congruence. Currently 67 species of bats are recognized for the fauna of Argentina. Notwithstanding the geographical records of the species are well documented, their distributional patterns on a national scale have not been studied so far. In this study, we analyze all the validated records, in order to identify patterns of species richness and distributional congruence. The highest species richness was located in the Paraná forest (northeast) and the Yungas forest (northwest), with a marked drop in richness in the latitudinal gradient. The coincidence of the geographical ranges of the species de ned a total of 47 consensus areas of distributional congruence, and each one was assigned to one of eight identi ed patterns: the Yungas, the northern sector of the Yungas (nested with the previous one), the northeast, a disjunct pattern that includes the northwest and northeast of the country, the Chaco region along with other surrounding regions, and the Patagonian region.

阿根廷蝙蝠的生物地理格局：物种丰富度和分布一致性。目前，阿根廷有67种蝙蝠被确认为动物。尽管该物种的地理记录有很好的记录，但到目前为止，还没有对其在全国范围内的分布模式进行研究。在这项研究中，我们分析了所有经过验证的记录，以确定物种丰富度和分布一致性的模式。物种丰富度最高的是Paraná森林（东北部）和Yungas森林（西北部），在纬度梯度上丰富度显著下降。该物种地理范围的一致性总共决定了47个分布一致的一致区域，每个区域都被分配到八个相同模式中的一个：云冈、云冈北部（与前一个嵌套）、东北部，一种包括该国西北部和东北部的间断模式，查科地区和其他周边地区以及巴塔哥尼亚地区。Recibido:2020年12月30日。Aceptado：2020年12月1日。编辑：U.F.J.Pardiñas和C.A.Galliari。2 Mastozooología Neotropical，en prensa，Mendoza，2021 h p://www.sarem.org.ar–h p://http://www.bmz.org M.L.Sandoval Salinas等人。51种（占总数的76%）是特征种。发现的几个模式与其他生物（植物和动物）的恢复区域一致，这可能表明该地区大部分生物群存在具有共同历史的区域。Palabras clave：查科，穆尔西耶拉戈斯，巴塔哥尼亚，生物地理保护区，云加斯。

. The tropical genus Heteromys includes 17 species that have undergone several taxonomic changes and have unclear interspecific limits. We compared the intraspecific, interspecific, and geographic variation in ten species of Heteromys using geometric morphometrics, and evaluated whether the genetic differences between the species were reflected in differences in cranial morphology. We digitized three cranial views and one mandibular view of 638 adult specimens, and performed morphometric analyses. Sexual variation and differences in cranial morphology were evaluated with analysis of variance, multivariate analysis of variance, and canonical variate analysis. Cranial differences were observed with deformation grids, and a cluster analysis was performed with Procrustes distances to compare with a phylogenetic tree. The geographic variation analyses were carried out using clusters based on physiographic regions. Only H. desmarestianus and H. irroratus presented sexual variation. Heteromys species showed differences between physiographic regions probably due to variation in abiotic factors, vegetation cover, and precipitation. Each species had a distinctive morphotype, with differences in their rostri, zygomatic arches, cranial vaults, occipitals, and foramina magna, as well as in the angular processes, condylar processes, and diastemas of the mandibles. The species clusters matched with clades previously identified by molecular markers. The specimens of one candidate species ( Heteromys sp.) showed unique morphometric characteristics that separated them from the other species.

Los resultados obtenidos sugieren que ambas variables influyen en la frecuencia de los comportamientos. Las actividades más frecuentes fueron búsqueda de alimento y descanso. Este estudio aporta datos que pueden contribuir a planes de manejo en el ecosistema marino austral. ABSTRACT. Habitat use of Peale’s dolphin Lagenorhynchus australis in the Beagle Channel, Tierra del Fuego, Argentina. Peale’s dolphin is one of the most common species of cetaceans in Tierra del Fuego, Argentina. However, limited information exists about the local population. In order to characterize the habitat use by Peale’s dolphin, land-based observations were carried out during a summer season. Behavioral patterns were studied in relation to tidal cycles and kelp forest, and the main activities displayed were determined. Foraging and resting were the most frequent behaviors observed. Dolphin’s behavior seems to be related to the tidal cycle and to its position relative to the kelp bed. This study provides data that can contribute to management plans of the austral marine ecosystem.

. Diet of culpeo fox Lycalopex culpaeus (Molina, 1782) during the mega-drought of central Chile: role of cattle and evidence of a high trophic interaction between carnivorous mammals. Chile has experienced a strong drought, which has been sustained since 2010. In this context, we conducted a trophic study for Lycalopex culpaeus , in the Chilean Mediterranean area, during this extreme climatic event to analyze how this phenomenon of restriction in the availability of trophic resources affects the diet of these foxes. The analysis of feces allows us to observe that L. culpaeus based its diet on lagomorphs and on the use of cattle, probably dead. During the study there was no change in foxes activity. Another interesting aspect was the sustained presence of carnivorous mammals in the feces throughout the year; the latter supports what has been observed in other regions, in that interspecific kills are common among carnivorous mammals.

. Small rodents rely on resource gathering during the breeding season to support their reproductive output and offspring survival. Since croplands may provide complementary food sources, we evaluated the influence of the presence of cornfield on the forest edge in Oligoryzomys nigripes (Olfers, 1818) abundance and breeding. We found that abundance, proportion of reproductive females and males, as well as the number of juveniles were higher in the cornfield-forest edges, with no seasonality, a pattern divergent from the seasonal reproduction described for the species. Therefore, our results supported the hypothesis of cornfields benefiting O. nigripes abundance and breeding success.

. The colonies of South American fur seals, Arctocephalus australis (SAFS), are currently experiencing population recovery, and as a consequence many coastal areas have been reoccupied. These areas are often haul-out sites used by SAFS for resting during the post-reproductive (winterly) season, and may be playing a key role in the population recovery process since they seem to be located close to winter feeding areas that are far from the breeding colonies. This study reports on the trend in abundance of SAFS in a recently reoccupied winter area, the San Matías Gulf (SMG). The trend was evaluated with generalized linear models between 2007 and 2017 in two sectors of the SMG, Islote Lobos, the only rookery of this species in the area, and the northwest marine area of the gulf. Both sectors showed a negative trend. For Islote Lobos, the best selected models estimated a mean annual rate between -12.2% and -17.6%, SAFS observados en 2007 pueden haber seleccionado otros hábitats durante los siguientes años. Sin embargo, para comprender los procesos de redistribución y recolonización se necesitan censos simultáneos en todo su rango de distribución.

. Brazil is considerate one of the countries with the highest diversity of mammals in the world. However, there are still many gaps in the knowledge of the ecology of mammalian species and because they are threatened by anthropic activities, it becomes increasingly necessary to gather information that contributes to their conservation. We characterized the medium and large-sized mammals in the Caparaó National Park (CNP), by analyzing species richness and frequency of records (hereafter abundance) in the two main vegetation types (i.e., Ombrophilous Forest and High Elevation Grasslands) found in the park. We carried out active searches and installed camera traps associated with sand-plots in 30 sampling sites. We performed rarefaction curves to verify that the sampling effort was sufficient to characterize species richness of the CNP, and we ordered the data obtained for species composition and abundance using a Non-Metric Multidimensional Scaling and assessed the relationship between the season (dry and rainy seasons) and vegetation types on mammalian species richness with a two-way analysis of variance. We recorded 34 native species of medium and large mammals and one exotic species ( Canis lupus familiaris ). Species composition and abundance differed between vegetation types. The Ombrophilous Forest presented higher species richness than the High Elevation Grasslands, which demonstrates that the medium and large mammalian community may be influenced by the environmental complexity. The CNP holds a rich community of medium and large mammals, with many endemic and endangered species of the Atlantic Forest.
