Non‐consumptive predator effects on prey population size: A dearth of evidence

MJ Sheriff, SD Peacor, D Hawlena… - Journal of Animal …, 2020 - Wiley Online Library
There is a large and growing interest in non‐consumptive effects (NCEs) of predators.
Diverse and extensive evidence shows that predation risk directly influences prey traits …

[HTML][HTML] Dynamics of a predator-prey system with fear and group defense

SK Sasmal, Y Takeuchi - Journal of Mathematical Analysis and …, 2020 - Elsevier
We study the dynamics of a prey-predator interaction model that incorporates:(1) reduction
of prey growth rate, in the form of fear effect, in presence of predator; and (2) group defense …

Compensatory mechanisms for ameliorating the fundamental trade-off between predator avoidance and foraging

JS Thaler, SH McArt, I Kaplan - Proceedings of the National …, 2012 - National Acad Sciences
Most organisms face the problem of foraging and maintaining growth while avoiding
predators. Typical animal responses to predator exposure include reduced feeding …

Integrating behaviour with life history: boldness of the field cricket, Gryllus integer, during ontogeny

PT Niemelä, A Vainikka, AV Hedrick… - Functional …, 2012 - Wiley Online Library
According to a recent hypothesis, personality traits should form integrative pace‐of‐life
syndromes with life‐history traits. Potential life‐history traits that explain personality variation …

Chaotic dynamics of a plankton-fish system with fear and its carry over effects in the presence of a discrete delay

B Dubey, SK Sasmal - Chaos, Solitons & Fractals, 2022 - Elsevier
Plankton-fish interactions are the central topic of interest related to marine ecology. Apart
from the direct predation (lethal effect) of zooplankton by fish, there are some non-lethal …

A phytoplankton–zooplankton–fish model with chaos control: In the presence of fear effect and an additional food

S Sajan, SK Sasmal, B Dubey - Chaos: An Interdisciplinary Journal of …, 2022 - pubs.aip.org
The interplay of phytoplankton, zooplankton, and fish is one of the most important aspects of
the aquatic environment. In this paper, we propose to explore the dynamics of a …

On the practical usage of genetic algorithms in ecology and evolution

S Hamblin - Methods in Ecology and Evolution, 2013 - Wiley Online Library
Genetic algorithms are a heuristic global optimisation technique mimicking the action of
natural selection to solve hard optimisation problems, which has enjoyed growing usage in …

Predator-induced changes in the boldness of naïve field crickets, Gryllus integer, depends on behavioural type

PT Niemelä, N DiRienzo, AV Hedrick - Animal Behaviour, 2012 - Elsevier
In recent years, using a personality approach for studies of animal behaviour has increased
our ability to predict an individual's or population's behavioural responses to external stimuli …

Sexual-size dimorphism modulates the trade-off between exploiting food and wind resources in a large avian scavenger

PAE Alarcón, JM Morales, JA Donázar… - Scientific Reports, 2017 - nature.com
Animals are expected to synchronize activity routines with the temporal patterns at which
resources appear in nature. Accordingly, species that depend on resources showing …

When relative allocation depends on total resource acquisition: implication for the analysis of trade‐offs

S Descamps, JM Gaillard, S Hamel… - Journal of evolutionary …, 2016 - academic.oup.com
A central tenet of evolutionary biology states that life‐history traits are linked via trade‐offs,
as classically exemplified by the van Noordwijk and de Jong model. This model, however …
