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

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.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, EarlyView.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

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.

Long‐term benefits of burns for large mammal habitat undermined by large, severe fires in the American West

Ecography, EarlyView.
Escalating wildfire frequency and severity are altering wildland habitats worldwide. Yet investigations into fire impacts on wildlife habitat rarely extend to the macroecological scales relevant to species conservation and global change processes. We evaluate the effects of wildfire on habitat quality and selection by large mammals spanning three ...
