From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Surplus killing by pumas Puma concolor: rumours and facts

Mammal Review, 2018
Abstract Surplus killing (i.e. predation in which predators kill more prey than necessary to satiate their hunger) appears to be widespread in carnivores and has the potential to exacerbate human–carnivore conflict. Nevertheless, little is known about the frequency of surplus killing or about its impact on livestock.

Segmental composition and nerve distribution of the brachial plexus in Galictis cuja

The Anatomical Record, EarlyView.
Abstract Galictis cuja is a neotropical mustelid with terrestrial locomotor habits, yet the anatomy of its brachial plexus has remained undescribed. This study characterizes the origin, organization, and distribution of the brachial plexus nerves in 15 adult specimens (30 antimeres).

Cat, cougar, and jaguar spermatogenesis: a comparative analysis

Brazilian Archives of Biology and Technology, 2006
This work presents a comparative review about the spermatogenic process in cats (Felis domestica), jaguars (Panthera onca) and cougars (Puma concolor), with emphasis on testicular biometry, gonadossomatic index, volumetric proportion of testicular ...

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

The Journal of Wildlife Management, EarlyView.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).

Cougar Dispersal and Natal Homing in a Desert Environment

, 2018
We present a review of cougar dispersal literature and the first evidence of natural (i.e., unmanipulated) homing behavior by a dispersing male cougar (Puma concolor) that sustained severe injuries crossing the northern Mojave Desert.

Assessing temporal genetic variation in a cougar population: influence of harvest and neighboring populations [PDF]

, 2015
The geography of the Black Hills region of South Dakota and Wyoming may limit connectivity for many species. For species with large energetic demands and large home ranges or species at low densities this can create viability concerns. Carnivores in this

Familiarity and aggression shape long‐term associations and mortality risk in a solitary ungulate

Oikos, EarlyView.
Periodic social interactions are important to animal fitness, even in solitary species. For solitary species, these interactions can be unexpected and shaped by previous encounters. Despite being aggressive and largely solitary, black rhinoceroses Diceros bicornis are commonly seen in groups, suggesting they may engage in more social behaviours than ...
