Predator avoidance in extremophile fish [PDF]
, 2013 Extreme habitats are often characterized by reduced predation pressures, thus representing refuges for the inhabiting species. The present study was designed to investigate predator avoidance of extremophile populations of Poecilia mexicana and P ...

The effect of relatedness and pack size on territory overlap in African wild dogs
Movement Ecology, 2017 Background Spacing patterns mediate competitive interactions between conspecifics, ultimately increasing fitness. The degree of territorial overlap between neighbouring African wild dog (Lycaon pictus) packs varies greatly, yet the role of factors ...

Mammal predator and prey species richness are strongly linked at macroscales [PDF]
, 2013 Predator-prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large-scale gradients of species richness remains unexplored.

Intolerant baboons avoid observer proximity, creating biased inter-individual association patterns
Scientific Reports, 2022 Social network analysis is an increasingly popular tool for behavioural ecologists exploring the social organisation of animal populations. Such analyses require data on inter-individual association patterns, which in wild populations are often collected

Foraging behaviour and habitat-use drives niche segregation in sibling seabird species
Royal Society Open Science, 2020 To mediate competition, similar sympatric species are assumed to use different resources, or the same but geographically separated resources. The two giant petrels (Macronectes spp.) are intriguing in that they are morphologically similar seabirds with ...

Animal-borne acoustic data alone can provide high accuracy classification of activity budgets
Animal Biotelemetry, 2021 Background Studies on animal behaviour often involve the quantification of the occurrence and duration of various activities. When direct observations are challenging (e.g., at night, in a burrow, at sea), animal-borne devices can be used to remotely ...

Morphometry of the reproductive system of the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera, Pentatomidae) when submitted to different temperatures [PDF]
Ciência Rural, 2020 : In order to manipulate the mass rearing of natural enemies, temperature variations can be used. The effects are widely studied for their survival and developmental duration; however, there is little information about their reproductive system in the ...

Geometric factors influencing the diet of vertebrate predators in marine and terrestrial environments [PDF]
, 2014 Predator–prey relationships are vital to ecosystem function and there is a need for greater predictive understanding of these interactions. We develop a geometric foraging model predicting minimum prey size scaling in marine and terrestrial vertebrate ...

The utility of accelerometers to predict stroke rate in captive fur seals and sea lions
Biology Open, 2017 The energy expenditure of free-living fur seals and sea lions is difficult to measure directly, but may be indirectly derived from flipper stroke rate. We filmed 10 captive otariids swimming with accelerometers either attached to a harness (Daily Diary ...

Developmental changes in foraging-predator avoidance trade-offs in larval lumpfish Cyclopterus lumpus [PDF]
, 1991 The 5-12 wk old larvae increased time spent clinging to a surface in the presence of a predator, trading-off time available for foraging in order to reduce the probability of attack.
