When optimal foragers meet in a game theoretical conflict: A model of kleptoparasitism.

Journal of Theoretical Biology, 2020
Kleptoparasitism can be considered as a game theoretical problem and a foraging tactic at the same time, so the aim of this paper is to combine the basic ideas of two research lines: evolutionary game theory and optimal foraging theory.

Linking behavior and predation data improves inference on interspecific risk perception in carnivores

Ecosphere
Competition between carnivores and scavengers can alter predation rates and foraging behavior, shaping the effects of predation on complex community dynamics.

Comportamento associativo de Fregata magnificens (Fregatidae, aves) e Sula lecogaster (sulidae, aves) no litoral centro-norte do estado de São Paulo Associative behaviour of the Fregata magnificiens (fregatidae, Aves) and Sula leucogaster (Sulidae, Aves) in the São Paulo State littoral

Brazilian Journal of Oceanography, 1987
O habito da fregata (Fregata magnificiens) de roubar peixes do atobã marrom (Sula lecogaster) é bem conhecido na literatura, comportamento este que tem nos levado a classificar a primeira espécie como sendo cleptoparasita da segunda.

Lively Transgressions at the Urban–Ocean Edge: Conflict, Coexistence and Animals on the Move

Transactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
Short Abstract The paper intervenes in recent debates on human–wildlife conflict and ‘Species on the Move’, drawing on cases of urban gulls in Northern Europe and sharks at Australian city beaches. The paper interrogates: representations of conflict and the interplay between media and policy; the relationship between mobility and the articulation of ...

Heterospecific foraging associations between reef-associated sharks: first evidence of kleptoparasitism in sharks.

Ecology, 2020
Social foraging allows groups of predators to search for, pursue, and capture prey with greater efficiency than using solitary hunting. It can vary in complexity and take many forms ranging from cooperative hunting, to social information sharing and ...

Kleptoparasitism and the distribution of unequal competitors [PDF]

Behavioral Ecology, 2002
Kleptoparasitism is an important means by which many animals obtain limited resources. The success of kleptoparasitism may be influenced by a number of factors, including competitive differences among individuals and the spatial distribution of prey and hosts.

Epizoic acoelomorph flatworms impair zooplankton feeding by the scleractinian coral Galaxea fascicularis

Biology Open, 2012
Summary Many scleractinian coral species host epizoic acoelomorph flatworms, both in aquaculture and in situ. These symbiotic flatworms may impair coral growth and health through light-shading, mucus removal and disruption of heterotrophic feeding.

Coexistence under constraint: Spatiotemporal co‐occurrence in a dryland carnivore guild

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Interspecific competition plays a crucial role in shaping the structure and dynamics of large carnivore guilds. Extreme temperatures and heightened resource heterogeneity in drylands can present additional challenges to intraguild coexistence, potentially making dryland carnivore guilds particularly susceptible to climate change and ...

Use of tusks by narwhals, Monodon monoceros, in foraging, exploratory, and play behavior

Frontiers in Marine Science
Despite the universal fascination with the tusk of the narwhal, the function of this long, spiraled tooth is still debated, primarily because few people have observed how narwhals (Monodon monoceros) use their tusks in the wild.
