Camouflage in predators [PDF]

open access: yesBiological Reviews, 2020
ABSTRACTCamouflage – adaptations that prevent detection and/or recognition – is a key example of evolution by natural selection, making it a primary focus in evolutionary ecology and animal behaviour. Most work has focused on camouflage as an anti‐predator adaptation. However, predators also display specific colours, patterns and behaviours that reduce

Foraging in a dynamic environment: Response of four sympatric sub‐Antarctic albatross species to interannual environmental variability

open access: yesEcology and Evolution, 2020
Seasonal and annual climate variations are linked to fluctuations in the abundance and distribution of resources, posing a significant challenge to animals that need to adjust their foraging behavior accordingly.

Consistency in the flight and visual orientation distances of habituated chacma baboons after an observed leopard predation. Do flight initiation distance methods always measure perceived predation risk?

open access: yesEcology and Evolution, 2021
Flight initiation distance (FID) procedures are used to assess the risk perception animals have for threats (e.g., natural predators, hunters), but it is unclear whether these assessments remain meaningful if animals have habituated to certain human ...

An interdisciplinary review of current and future approaches to improving human–predator relations

open access: yesConservation Biology, 2017
In a world of shrinking habitats and increasing competition for natural resources, potentially dangerous predators bring the challenges of coexisting with wildlife sharply into focus.

Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala

open access: yesNature, 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

Predating Predators

open access: yes, 2005
Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3.

An Economical Custom-Built Drone for Assessing Whale Health

open access: yesFrontiers in Marine Science, 2017
Drones or Unmanned Aerial Vehicles (UAVs) have huge potential to improve the safety and efficiency of sample collection from wild animals under logistically challenging circumstances.

Nonlethal Effects in the Ecology of Predator-Prey Interactions What are the ecological effects of anti-predator decision-making?

open access: yes, 1998
.P ]redator-prey interactions have long captured the attention of ecologists, and with good reason. Predation leads inevitably to the removal of prey individuals from ecological systems, which can have major impacts on prey population dynamics and on ...

Mind the gap: Experimental tests to improve efficacy of fladry for nonlethal management of coyotes

open access: yesWildlife Society Bulletin, 2019
Coyotes (Canis latrans) are the top predator of livestock in the contiguous United States. Developing more effective nonlethal tools to prevent coyote depredation will facilitate coexistence between livestock producers and coyotes.

Evaluating fladry designs to improve utility as a nonlethal management tool to reduce livestock depredation

open access: yesWildlife Society Bulletin, 2015
Nonlethal deterrents against carnivores are important components to protecting livestock and conserving carnivore populations. However, the performance of the visual deterrent called fladry, a historical tool used to defend livestock from carnivores, is ...
