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

Cascading top‐down effects of changing oceanic predator abundances
Journal of Animal Ecology, 2009 1. Top-down control can be an important determinant of ecosystem structure and function, but in oceanic ecosystems, where cascading effects of predator depletions, recoveries, and invasions could be significant, such effects had rarely been demonstrated ...

Chemotactic predator-prey dynamics [PDF]
, 2010 A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady hunting is unstable.

Stop Jumping the Gun: A Call for Evidence‐Based Invasive Predator Management
Conservation Letters, 2017 Invasive mammalian predators are major drivers of species extinctions globally. To protect native prey, lethal control is often used with the aim of reducing or exterminating invasive predator populations. The efficacy of this practice, however, is often

Predator‐induced stress and the ecology of fear
Functional Ecology, 2013 Summary Predator-induced stress has been used to exemplify the concept of stress for close to a century because almost everyone can imagine the terror of fleeing for one's life from a lion or a tiger.

PREDATOR: Registration of 3D Point Clouds with Low Overlap [PDF]
Computer Vision and Pattern Recognition, 2020 We introduce PREDATOR, a model for pairwise point-cloud registration with deep attention to the overlap region. Different from previous work, our model is specifically designed to handle (also) point-cloud pairs with low overlap.

Drone Observations of Marine Life and Human–Wildlife Interactions off Sydney, Australia
Drones, 2022 Drones have become popular with the general public for viewing and filming marine life. One amateur enthusiast platform, DroneSharkApp, films marine life in the waters off Sydney, Australia year-round and posts their observations on social media.

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

Scientific Reports, 2023 Many large predator populations are in decline globally with significant implications for ecosystem integrity and function. Understanding the drivers of their decline is required to adequately mitigate threats.

The context dependence of non-consumptive predator effects.
Ecology Letters, 2020 Non-consumptive predator effects (NCEs) are now widely recognised for their capacity to shape ecosystem structure and function. Yet, forecasting the propagation of these predator-induced trait changes through particular communities remains a challenge ...
