Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala [PDF]
Nature, 2018 The fastest and most manoeuvrable terrestrial animals are found in savannah habitats, where predators chase and capture running prey. Hunt outcome and success rate are critical to survival, so both predator and prey should evolve to be faster and/or more

Using accelerometers to develop time-energy budgets of wild fur seals from captive surrogates [PDF]
PeerJ, 2018 Background Accurate time-energy budgets summarise an animal’s energy expenditure in a given environment, and are potentially a sensitive indicator of how an animal responds to changing resources. Deriving accurate time-energy budgets requires an estimate

A critical assessment of marine predator isoscapes within the southern Indian Ocean
Movement Ecology, 2020 Background Precise and accurate retrospective geolocation of marine predators via their tissues’ isotopic composition relies on quality reference maps of relevant isotopic gradients (“isoscapes”).

When is general wariness favored in avoiding multiple predator types? [PDF]
, 2012 Free access to article and electronic appendices via DOI.Adaptive responses to predation are generally studied assuming only one predator type exists, but most prey species are depredated by multiple types.

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 ...
