The Gestation Delay: A Factor Causing Complex Dynamics in Gause‐Type Competition Models

open access: yesComplexity, Volume 2018, Issue 1, 2018., 2018
In this paper, we consider a Gause‐type model system consisting of two prey and one predator. Gestation period is considered as the time delay for the conversion of both the prey and predator. Bobcats and their primary prey rabbits and squirrels, found in North America and southern Canada, are taken as an example of an ecological system.

Particle Motion around Charged Black Holes in Generalized Dilaton‐Axion Gravity

open access: yesAdvances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
The behaviour of massive and massless test particles around asymptotically flat and spherically symmetric, charged black holes in the context of generalized dilaton‐axion gravity in four dimensions is studied. All the possible motions are investigated by calculating and plotting the corresponding effective potential for the massless and massive ...

Desnacionalización, Regímenes Visuales y Resistencia: Gitanos Americanos en Ciudad de México

open access: yesCultural Anthropology, Volume 39, Issue 2, Page 171-193, May 2024.

Evaluating the dependence of opportunistic Yellow‐legged Gulls (Larus michahellis) on marine habitat and fishing discards

open access: yesIbis, Volume 166, Issue 1, Page 112-128, January 2024.
Several bird species benefit from anthropogenic food subsidies, such as landfills and fishing discards, that are being reduced owing to introduced legislation.
