Microhabitat conditions drive uncertainty of risk and shape neophobic responses in Trinidadian guppies, Poecilia reticulata

LEA Feyten, IW Ramnarine, GE Brown - Ecology and Evolution, 2023 - Wiley Online Library
In response to uncertain risks, prey may rely on neophobic phenotypes to reduce the costs
associated with the lack of information regarding local conditions. Neophobia has been …

The propensity for re-triggered predation fear in a prey fish

AL Crane, LEA Feyten, IW Ramnarine, GE Brown - Scientific Reports, 2020 - nature.com
Variation in predation risk can drive variation in fear intensity, the length of fear retention,
and whether fear returns after waning. Using Trinidadian guppies, we assessed whether a …
