, 1994 Factors influencing calf survival are predation, insects, weather, diseases, and-ultimately-dam condition. In addition, reindeer calves on the Seward Peninsula are also subjected to annual herding and handling.

The Anatomical Record, EarlyView.Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Local biodiversity change reflects interactions among changing abundance, evenness, and richness
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract Biodiversity metrics often integrate data on the presence and abundance of multiple species. Yet our understanding of covariation between changes to the numbers of individuals, the evenness of species relative abundances, and the total number of species remains limited.

Dynamical behavior of Predator-Prey with Allee Effect on Both Populations and Disease in Predator [PDF]
arXivIn the current study, we took into account a model of nonlinear ``predator-prey'' interactions including the ``Allee effect'' on both populations and disease in the predator population. The population as a whole is split into three: the prey population, susceptible predator, and diseased predator. The ``Takagi-Sugeno (T-S) impulsive control model'' and

Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis
The Anatomical Record, EarlyView.Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Substrate size modifies stream grazer–biofilm interactions in the presence of invertivorous fish
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract When herbivore abundance is controlled by predators there may be an indirect positive effect on primary producers due to reduced grazing pressure, but the potential of predation refuges to modify such trophic cascades has rarely been studied.

Behavioral trade‐offs and multitasking by elk in relation to predation risk from Mexican gray wolves
Ecology and EvolutionPredator non‐consumptive effects (NCE) can alter prey foraging time and habitat use, potentially reducing fitness. Prey can mitigate NCEs by increasing vigilance, chewing‐vigilance synchronization, and spatiotemporal avoidance of predators. We quantified
