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

Predation domes: In‐situ field assays to measure predatory behaviours by fish

open access: yesMethods in Ecology and Evolution, 2023
Biotic interactions such as predation are difficult ecological processes to quantify in the wild. This is especially the case in the marine environment due to logistical difficulties in capturing animal behaviour.

Predator confusion is sufficient to evolve swarming behavior [PDF]

open access: yesJ. Royal Society Interface 10 (2013) 2010305, 2012
Swarming behaviors in animals have been extensively studied due to their implications for the evolution of cooperation, social cognition, and predator-prey dynamics. An important goal of these studies is discerning which evolutionary pressures favor the formation of swarms.

Field margins enhance weed seed predation in adjacent fields in early spring

open access: yesFrontiers in Agronomy, 2023
Seed depletion by granivorous organisms can regulate weeds in arable agriculture. Enhancing this regulation can be achieved by adopting farming practices that favour seed predators.

The balance between contamination and predation determine species existence in prey-predator dynamics with contaminated and uncontaminated prey [PDF]

open access: yesarXiv, 2023
In freshwater ecosystems, aquatic insects that ontogenetically shift their habitat from aquatic to terrestrial play vital roles as prey subsidies that move nutrients and energy from aquatic to terrestrial food webs. As a result, these subsidies negatively affect alternative terrestrial prey by enhancing predator density.

Rat snakes, cowbirds, and vines lower passerine nest survival in remnant bottomland hardwood forests in east-central Arkansas, USA

open access: yesAvian Conservation and Ecology, 2021
Predation is often the leading cause of nest failure among passerines; however, specific causes are often unknown or can be misidentified in the field.

Identification of predation events in wild fish using novel acoustic transmitters

open access: yesAnimal Biotelemetry, 2020
Background Acoustic telemetry is a commonly used tool to gain knowledge about aquatic animal ecology through the study of their movements. In telemetry studies researchers must make inferences regarding the movements and the fates of tagged animals ...

Global solvability of a predator-prey model with predator-taxis and prey-taxis [PDF]

open access: yesarXiv, 2021
This paper is concerned with a diffusive predator-prey model with predator-taxis and prey-taxis. Based on the Schauder fixed point theorem, we prove the global existence, uniqueness and boundedness of the classical solutions under the conditions that the predator-taxis and prey-taxis effects are weak enough.

Synthesis Human-caused Disturbance Stimuli as a Form of Predation Risk

open access: yes, 2002
A growing number of studies quantify the impact of nonlethal human disturbance on the behavior and reproductive success of animals. Athough many are well designed and analytically sophisticated, most lack a theoretical framework for making predictions ...

Numbers and presence of guarding dogs affect wolf and leopard predation on livestock in northeastern Iran

open access: yesBasic and Applied Ecology, 2022
Livestock predation can pose socio-economic impacts on rural livelihoods and is the main cause of retaliatory killings of carnivores in many countries.
