The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

Mammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

Livestock depredation by large carnivores in northern Botswana

Global Ecology and Conservation, 2019
Human-carnivore conflict is a leading cause of large carnivore declines and minimizing these conflicts is vital to maintaining viable carnivore populations.

Balancing benefits and burdens: Tourist camps and lion conservation in the Maasai Mara

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Wildlife tourism supports conservation and economies, but its rapid expansion can negatively impact ecosystems. Using spatially explicit lion density data from the Maasai Mara (2014–2022), we found that higher densities of tourist camps significantly reduce lion presence, independent of prey or vegetation, and that newly established camps displace ...

Asynchronous food-web pathways could buffer the response of Serengeti predators to El Niño southern oscillation [PDF]

, 2013
Understanding how entire ecosystems maintain stability in the face of climatic and human disturbance is one of the most fundamental challenges in ecology.

Evolutionary taxonomy and conservation status of environmentally sensitive and endangered musk deer (Moschus spp.): An updated review

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
This study reviews the historical taxonomic classification and evolutionary background of musk deer, clarifying long‐standing confusion in their identification. It highlights the current global distribution and conservation status of these species, emphasizing the threat posed by poaching and habitat destruction. The work aims to raise public awareness

A metapopulation approach to African lion (Panthera leo) conservation.

PLoS ONE, 2014
Due to anthropogenic pressures, African lion (Panthera leo) populations in Kenya and Tanzania are increasingly limited to fragmented populations. Lions living on isolated habitat patches exist in a matrix of less-preferred habitat. A framework of habitat

Well‐Posedness and Pattern Formation in a Two‐Species Reaction–Diffusion System with Nonlocal Perception

Studies in Applied Mathematics, Volume 156, Issue 2, February 2026.
ABSTRACT Nonlocal perceptual cues, such as visual, auditory, and olfactory signals, profoundly influence animal movement and the emergence of ecological patterns. To capture these effects, we introduce a two‐species reaction–diffusion system with mutual nonlocal perception on a two‐dimensional periodic domain.

Exposure to selected pathogens in Geoffroy's cats and domestic carnivores from central Argentina [PDF]

, 2012
Wild carnivores share a high percentage of parasites and viruses with closely related domestic carnivores. Because of increased overlap and potential contact with domestic species, we conducted a retrospective serosurvey for 11 common carnivore pathogens
