TL;DR: It is suggested that food availability, and not heat conservation, is the more important mechanism driving body size variation across rodent species at the order level.

TL;DR: The results suggest that ocelots may tailor their activity to that of some of their potential prey to increase the probability of encounters, and provide the first insight into temporal interactions involving ocelot and their possible prey in the Brazilian Pantanal.

TL;DR: This study suggests that the availability of three different ungulate species, the tigers’ preference for wild boar, and the diverse prey base ofLeopards contribute to the coexistence of tigers and leopards in this region.

TL;DR: It is suggested that as a species wild boar have a wide fundamental macronutrient niche, which likely contributes to the success of the species as an invader of novel environments.

TL;DR: Whether warmer winter evenings offer bats an opportunity for casual hunting or whether winter foraging expresses an urgent need for weak individuals is investigated to show.

TL;DR: Although the density estimate revealed a lesser number of feral horses per capita than blackbuck, the higher food consumption rate of the former coupled with larger body mass, could outweigh the higher density of blackbuck and the same is discussed as an effective ecological competitor.

TL;DR: These results add to the growing body of evidence calling for an extensive taxonomic revision of this group, and concur with previous recommendations that the generic taxonomic designation of Mazama should be applied not only to the red brocket deer but also to all of the species currently recognized under the genus Odocoileus.

TL;DR: It is shown that over the course of the relatively short period of co-existence between badgers and humans in Ireland, badgers have adapted to using the man-made field boundaries that have replaced native woodland.

TL;DR: The results suggest that smaller rabbit populations are those most vulnerable to the outbreak of RHDV 2 and are therefore likely to decline sharply or even become extinct.

TL;DR: The conserved pattern of level specific vertebral shapes suggests that the morphological and functional tripartition of the cervical spine could be a general trait of all mammalians.

TL;DR: A model of male haulouts spatially segregated from the central breeding areas, but with a summer recurrent flow of animals that contributes a significant proportion of the male population of northern Patagonia and Uruguay is suggested.

TL;DR: In this paper, the authors analyzed frequency, temporal and power variables of contact and bugle calls, collected from 63 Siberian wapiti Cervus elaphus sibiricus, the most abundant Asian subspecies of red deer.

TL;DR: This work reports the first data on reproductive biology and paternal behaviour of free-living crested porcupines in Europe, and confirms that alternation of cub guarding in den occurs in the first two months of life, when quills are still soft and relatively short, thus making cubs an easy prey for small and mesocarnivores.

TL;DR: This editorial briefly summarizes phylogenetic and taxonomic issues and provides guidelines to authors submitting their studies to Mammalian Biology in order to avoid errors in phylogenetic discussions and to do justice to the fundamental nature of species in biology.

TL;DR: The results demonstrate the importance of regenerating forest as habitat for medium- to large-sized mammal species and the effects of logging on mammal local abundance, which may no longer be detectable after 30 years.

TL;DR: The results obtained in this study increase the knowledge of trophic ecology for high Trophic level predators such as short-beaked common dolphins along the Argentina coast in support of effective conservation and management programs.

TL;DR: A mosaic of morphological features of the tayra, a combination of phylogenetic inertia and ecological signals, very likely evolved to promote the efficient and effective exploitation of diverse habitats and resources in this versatile species.

TL;DR: Geometric morphometrics shows that the Amazon animals differ from the others probably due to existing geographical barriers, which supports the need for a proper phylogenetic assessment of these populations, in order to clarify their taxonomic status.

TL;DR: There was no significant spatial trend in genetic structure for the mountain tapir in Colombia and Ecuador and the genetic heterogeneity analyses revealed a low genetic differentiation between them, suggesting that T. kabomani is not a full species.

TL;DR: Although an overlap of more than 80% was observed between the diets of Eld's deer and hog deer, there appears to be little competition among them for forage due to an abundant availability of high quality forage across seasons.

TL;DR: Despite the two armadillo species sharing several niche dimensions, they showed spatial and temporal segregation, which may be an adaptation to reduce interspecific competition but may also be affected by the need to avoid poaching pressures.

TL;DR: It is shown that roe deer currently occupies 85% of Catalonia territory, which represents an almost six-fold increase since the beginning of the 90s, and is recommended to release sites that contain large and suitable patches of habitat and that are sufficiently close to allow population continuity.

TL;DR: Activity patterns of five Mazama species in four biomes in South America show that clade assignment was the main predictor of diurnal versus nocturnal activity, thus suggesting a phylogenetic constraint rather than any other ecological influence on circadian activity.

TL;DR: Variation at the melanocortin receptor I (MC1R) and nuclear receptor subfamily 6, group A, member 1 (NR6A1) genes in European wild boar populations, two loci which have been under strong artificial selection during domestication are analysed.

TL;DR: A close relationship appears to exist between the major climatic episodes occurred during the Late Quaternary in the central region of Argentina and the main historical demographic changes inferred for C. “ chasiquensis ”, a highly, vulnerable and endemic subterranean rodent distributed in a very small area from the central part of Argentina.

TL;DR: The results support effects of ecological selection on the alarm call variables rather than the genetic drift hypothesis and support the current taxonomic separation between subspecies of speckled ground squirrels differing in diploid chromosome sets.

TL;DR: The results show that the maned sloth respond to fine local scale variables, but not to landscape structure, and the unquestionable importance of local variables for species occupancy within fragmented landscapes, such as those related with the forest structure, is reinforced.

TL;DR: Morphological analysis revealed close similarity and largely overlapping phenotypic variation between M. hajastanicus and Myotisaurascens, which strongly argue for a single species (M. aurascens) and the rejection of a local endemism.

TL;DR: Higher levels of haplotype and nucleotide diversities in the northern areas, together with the heterogeneous distribution of pairwise population differentiations and the weak signal for isolation-by-distance suggest the existence of long-dispersal migrants across the Iberian Peninsula.
