Why do dolphins form mixed-species associations in the Azores ?

, 2008
Mixed-species associations are temporary associations between individuals of different species that are often observed in birds, primates and cetaceans.

Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)

Neotropical Ichthyology, 2019
Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species composition, abundance, behavioral ...

Fission-fusion dynamics and group-size dependent composition in heterogeneous populations

, 2019
Many animal groups are heterogeneous and may even consist of individuals of different species, called mixed-species flocks. Mathematical and computational models of collective animal movement behaviour, however, typically assume that groups and ...

Identification and frequency of consumption of wild edible plants over a year in central Tunisia: a mixed-methods approach

, 2020
Objective: To identify wild plants used as food and assess their frequency of consumption over a year in a region of Tunisia where agriculture is undergoing a major transformation from smallholder farming to an intensive high-input agricultural system ...

Foraging behaviour of an omnivorous bird varies in mixed-species groups

Ethology Ecology & Evolution, 2022
In mixed-species groups (MSGs), individuals from different species may locate and communicate about the presence of predators and prey quickly and accurately but may compete for food and favourable positions in the flock. Thus, foraging behaviour is likely to change when individuals participate in MSGs compared with single-species groups (SSGs).

Effects of habitat composition and landscape structure on worker foraging distances of five bumblebee species [PDF]

, 2016
Bumblebees (Bombus spp.) are important pollinators of both crops and wild flowers. Their contribution to this essential ecosystem service has been threatened over recent decades by changes in land use, which have led to declines in their populations.

Exploring mixed-species grouping effects through antipredator mechanisms

, 2022
Predation is an important selective force for prey organisms, which have also developed different antipredator adaptions. Individuals of many animal species live in the group, which is generally believed to offer prey benefits from reduced predation risk and/or increased foraging efficiency.

Why don’tSaimiri oerstedii andCebus capucinus form mixed-species groups? [PDF]

International Journal of Primatology, 1989
The instances of association with Cebus capucinustroops were monitored for 11 months as part of a field study of Saimiri oerstediiin a tropical wet forest in Costa Rica, Parque Nacional Corcovado. Contrary to the usual situation in South America, where S. sciureusforms persistent mixed-species groups with Cebus apella,in Corcovado S.
