Predation risk reduces a female preference for heterospecific males in the green swordtail [PDF]
, 2016 The presence of a predator can result in the alteration, loss or reversal of a mating preference. Under predation risk, females often change their initial preference for conspicuous males, favouring less flashy males to reduce the risk of being detected ...

Wildlife responses to livestock guard dogs and domestic sheep on open range
Global Ecology and Conservation, 2021 Domestic sheep (Ovis aries) are an attractant to carnivores; however, sheep are often accompanied by humans and livestock guardian dogs (LGDs; Canis familiaris), which defend sheep from depredation.

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 ...

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.

Smelling out predators is innate in birds [PDF]
, 2011 The role of olfaction for predation risk assessment remains barely explored in birds, although predator chemical cues could be useful in predator detection under low visibility conditions for many bird species.

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 ...

Prey aggregation is an effective olfactory predator avoidance strategy [PDF]
, 2014 Predator–prey interactions have a major effect on species abundance and diversity, and aggregation is a well-known anti-predator behaviour. For immobile prey, the effectiveness of aggregation depends on two conditions: (a) the inability of the predator ...

Tearing Out the Income Tax by the (Grass)Roots [PDF]
, 2011 Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.
