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 ...

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 ...

Interspecific Conformity and Asymmetric Behavioral Convergence in Drosophila [PDF]
Ecology and EvolutionMany animals form mixed‐species groups. Interactions among individuals within a group often induce behavioral conformity, forming group‐level characteristics.

Socio-ecological factors shaping mixed-species groups [PDF]
, 2019 Understanding why individuals form groups that are strikingly diversein their organisation is a central focus in evolutionary ecology. Although mixed-species groups, where members of different species interact and move together, are common across animal taxa, inter-species interactions have often been a point of secondary interest in the study of ...

Using Social Network Analysis to Assess ‘Groupness’ in a Mixed-Species Zoo Exhibit of Tufted Capuchins (Sapajus apella) and Squirrel Monkeys (Saimiri sciureus) [PDF]
AnimalsMixed-species groups have been recorded in various primates, including tufted capuchin and squirrel monkeys. Measures of their ‘groupness’ are typically based on factors such as group stability, social interactions, proximity, or behavioural coordination.

Temporal avoidance as a means of reducing competition between sympatric species
Royal Society Open Science, 2023 Human activity has modified the availability of natural resources and the abundance of species that rely on them, potentially changing interspecific competition dynamics.

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 ...

Avian Research, 2023 In mutualistic interactions, all parties are usually considered to benefit; yet there may be asymmetries in mutualisms where some partners/individuals benefit more than others.

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.

PLoS ONE, 2023 Mixed species exhibits in zoos are used to create larger, more stimulating environments to support naturalistic interactions between species. In the wild, mixed species groups are observed as having lower rates of vigilance, presumably due to reduced ...
