Frontiers in Marine Science, 2021 Numerous species of cetaceans have been recorded in mixed-species groups (MSGs). By forming groups with individuals of different species, cetaceans may reduce predation risk, improve foraging, and gain social benefits.

Vigilance of mustached tamarins in single-species and mixed-species groups—the influence of group composition [PDF]
Behavioral Ecology and Sociobiology, 2009 Species that participate in mixed-species groups (MSG) may have complementary roles in antipredator strategies. We studied vigilance in mustached tamarins (Saguinus mystax), small arboreal primates that form stable mixed-species groups with saddleback tamarins (Saguinus fuscicollis), in order to examine how the direction of vigilance changes with ...

Modeling vigilance in mixed‐species groups [PDF]
Natural Resource Modeling, 2022 AbstractMixed‐species groups are usually explained by foraging advantages and reduced predation risk for at least one of the participating species. Given that animals trade‐off foraging and vigilance, the optimal level of vigilance of individuals in mixed‐species groups depends partly on the vigilance levels of both conspecifics and heterospecifics ...

Comparing single- and mixed-species groups in fruit flies: differences in group dynamics, but not group formation [PDF]
Journal of Heredity, 2021 AbstractMixed-species groups describe active associations among individuals of 2 or more species at the same trophic level. Mixed-species groups are important to key ecological and evolutionary processes such as competition and predation, and research that ignores the presence of other species risks ignoring a key aspect of the environment in which ...

Diversity in mixed species groups improves success in a novel feeder test in a wild songbird community. [PDF]
Sci Rep, 2017 Mixed-species groups are common and are thought to provide benefits to group members via enhanced food finding and antipredator abilities. These benefits could accrue due to larger group sizes in general but also to the diverse species composition in the

Can mixed-species groups reduce individual parasite load? A field test with two closely related poeciliid fishes (Poecilia reticulata and Poecilia picta). [PDF]
PLoS ONE, 2013 Predation and parasitism are two of the most important sources of mortality in nature. By forming groups, individuals can gain protection against predators but may increase their risk of being infected with contagious parasites.

Cohesion, order and information flow in the collective motion of mixed-species shoals [PDF]
Royal Society Open Science, 2018 Despite the frequency with which mixed-species groups are observed in nature, studies of collective behaviour typically focus on single-species groups.

Behavioral Ecology and Sociobiology, 2023 Mixed-species groups are common amongst diverse taxa including fishes, birds, and mammals. Antipredator, foraging, and social benefits have been proposed as functional explanations for mixed-species group formation.

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 ...

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.
