Anti-predator behavioral variation among Physa acuta in response to temporally fluctuating predation risk by Procambarus

MP Kain, MW McCoy - Behavioural Processes, 2016 - Elsevier
Research in behavioral ecology routinely quantifies individual variation in behavior using
transitions between discrete environments, for example prey moving from a no predator to …

Among‐individual behavioral responses to predation risk are invariant within two species of freshwater snails

BJ Toscano, H Allegue, NJ Gownaris, M Drausnik… - Ethology, 2023 - Wiley Online Library
Prey behavioral response to predation risk drives a range of ecological and evolutionary
processes. Key to these effects is the degree to which conspecifics exhibit consistent …

Behavioral types of predator and prey jointly determine prey survival: potential implications for the maintenance of within-species behavioral variation

JN Pruitt, JJ Stachowicz, A Sih - The American Naturalist, 2012 - journals.uchicago.edu
Recent studies in animal behavior have emphasized the ecological importance of individual
variation in behavioral types (eg, boldness, activity). Such studies have emphasized how …

The influence of temporally variable predation risk on indirect interactions in an aquatic food chain

JM Wojdak, DC Trexler - Ecological Research, 2010 - Springer
We know little about how temporally variable predation risk influences prey behavior. The
risk allocation hypothesis predicts that prey facing more frequent risk should show weak anti …

Temporal environmental variation and phenotypic plasticity: a mechanism underlying priority effects

J T. Hoverman, R A. Relyea - Oikos, 2008 - Wiley Online Library
Understanding the role of history in the formation of communities has been a major
challenge in community ecology. Here, we explore the role of phenotypic plasticity and its …

Smaller and bolder prey snails have higher survival in staged encounters with the sea star Pisaster giganteus

WC Foster, CM Armstrong, GT Chism… - Current Zoology, 2017 - academic.oup.com
Temporally consistent individual differences in behavior, also known as animal personality,
can have large impacts on individual fitness. Here, we explore the degree to which …

Spatial and temporal scales of predator avoidance: experiments with fish and snails

AM Turner, SL Montgomery - Ecology, 2003 - Wiley Online Library
Predators often induce shifts in the traits of nearby prey, and these trait shifts are important in
mediating a variety of evolutionary and ecological processes. However, little is known about …

Prey responses to pulses of risk and safety: testing the risk allocation hypothesis

A Sih, TM McCarthy - Animal Behaviour, 2002 - Elsevier
The risk allocation hypothesis predicts that prey responses to predation risk should depend
on the temporal pattern of risk. In systems where activity is dangerous, predicted activity …

Different morphological traits influence predator defense and space use in Physa acuta

B Stevison, B Kensinger, B Luttbeg - American Malacological Bulletin, 2016 - BioOne
Individuals can respond to predation risk by building morphological defenses or by altering
their behavior. We tested whether freshwater Physa acuta (Draparnaud, 1805) snails with …

Scale and the guild functional response: density-dependent predation varies with plot size

WC Long, AH Hines - Journal of Experimental Marine Biology and Ecology, 2012 - Elsevier
The predator functional response is an important mechanism determining the persistence of
prey species; however, little is known about the effects of spatial scale on the functional …
