Ecology, opportunity or threat? Drivers of the caracal (Caracal caracal) population decline in South Africa

African Journal of Ecology, Volume 61, Issue 4, Page 768-780, December 2023., 2023
Abstract Anecdotal evidence suggests that there is interspecific competition between black‐backed jackal (Canis mesomelas) and caracal (Caracal caracal) on farmland in South Africa. Home range data were used across both years (1983–2016) and provinces, as well as polynomial interpolation, to quantitatively assess changes in the population of caracal ...

Dynamic balancing of risks and rewards in a large herbivore: Further extending predator–prey concepts to road ecology

Journal of Animal Ecology, Volume 92, Issue 10, Page 1954-1965, October 2023., 2023
The authors tested whether animals dynamically balance risks and rewards in the context of road crossings. Using extensive field‐based and GPS data from elk in Yoho National Park, the authors demonstrate that animals can modulate their selection for foraging resources with the risks they experience relative to roads while travelling.

Finding a safe space: Denning range dynamics of African wild dogs in Zimbabwe

African Journal of Ecology, Volume 61, Issue 3, Page 561-572, September 2023., 2023
Abstract African wild dogs utilise a den for ~10–12 weeks after birthing, during which home ranges are contracted and usually in areas away from roads and water sources, with low prey and predator abundances, high terrain ruggedness and vegetation cover.

Quantitative fatty acid signature analysis reveals a high level of dietary specialization in killer whales across the North Atlantic

Journal of Animal Ecology, Volume 92, Issue 6, Page 1216-1229, June 2023., 2023
An international team of scientists estimated the diets of the largest number of North Atlantic killer whales to date, revealing differences in feeding habits between and within populations. To quantify killer whales' diets, researchers looked at the fatty acid (lipid) composition of the animals' blubber.

Optimal foraging of lions at the human wildlands interface

African Journal of Ecology, Volume 61, Issue 2, Page 306-319, June 2023., 2023
Abstract Optimal foraging and landscape of fear theories provide frameworks which can be useful for investigating animal's space and prey use decisions. Predators, such as African lions Panthera leo, are likely to respond to prey abundance, accessibility, profitability and potential risks, often anthropogenic in nature, while making foraging decision ...
