Refining the stress gradient hypothesis for mixed species groups of African mammals [PDF]
Scientific Reports, 2022 Species interactions such as facilitation and predation influence food webs, yet it is unclear how they are mediated by environmental gradients. Here we test the stress gradient hypothesis which predicts that positive species interactions increase with ...

Seasonal patterns of mixed species groups in large East African mammals. [PDF]
PLoS ONE, 2014 Mixed mammal species groups are common in East African savannah ecosystems. Yet, it is largely unknown if co-occurrences of large mammals result from random processes or social preferences and if interspecific associations are consistent across ...

Mixed-species groups in bats: non-random roost associations and roost selection in neotropical understory bats [PDF]
Frontiers in Zoology, 2021 Background Mixed-species groups in animals have been shown to confer antipredator, foraging and other benefits to their members that may provide selective advantages.

Mixed-species groups and aggregations: shaping ecological and behavioural patterns and processes. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2023 Mixed-species groups of birds, fishes and mammals have traditionally been described in taxa-specific journals. However, mixed-species systems are actually more widely found when one includes aggregative (non-moving) systems, such as those common in amphibians and invertebrates.

Mixed-species groups and the question of dominance in the social ecosystem. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2023 Dominance interactions and hierarchies are of long-standing interest in the field of animal behaviour. Currently, dominance hierarchies are viewed as complex social structures formed by repeated interactions between individuals. Most studies on this phenomenon come from single-species groups.

Living in mixed species groups promotes predator learning in degraded habitats [PDF]
Scientific Reports, 2021 Living in mix-species aggregations provides animals with substantive anti-predator, foraging and locomotory advantages while simultaneously exposing them to costs, including increased competition and pathogen exposure.

Anthropogenic disturbance and mixed-species groups
Frontiers in Ecology and EvolutionMixed-species groups (MSGs) are composed of individuals of two or more species with such close associations that they can be regarded as members of the same social group.

Mixed-species groups of Serengeti grazers: a test of the stress gradient hypothesis. [PDF]
Ecology, 2020 AbstractUnderstanding the role of species interactions within communities is a central focus of ecology. A key challenge is to understand variation in species interactions along environmental gradients. The stress gradient hypothesis posits that positive interactions increase and competitive interactions decrease with increasing consumer pressure or ...

Improper Primate Release Fuels Interspecific Mating: Cases of Two Mixed‐Species Groups in Bangladesh [PDF]
Ecology and EvolutionWildlife trafficking has escalated in recent years, leading to a rise in animal rescues every year. In Bangladesh, increasing numbers of primates are being rescued from illegal trades and private collections.

Do mixed-species groups of capuchin (Sapajus apella) and squirrel monkeys (Saimiri sciureus) synchronize their behaviour? [PDF]
Philos Trans R Soc Lond B Biol Sci, 2023 In the wild, coordinated behaviour across group members is essential for maintaining spatial coherence, with potential implications for individual fitness.
