Exploring the effects of anthropogenic disturbance on predator inspection activity in Trinidadian guppies

Author(s): Brusseau AJP; Feyten LEA; Crane AL; Brown GE;

No abstract available

Article GUID: 38476138


Uncertainty about predation risk: a conceptual review

Author(s): Crane AL; Feyten LEA; Preagola AA; Ferrari MCO; Brown GE;

Uncertainty has long been of interest to economists and psychologists and has more recently gained attention among ecologists. In the ecological world, animals must regularly make decisions related to finding resources and avoiding threats. Here, we describ ...

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

Author(s): Feyten LEA; Ramnarine IW; Brown GE;

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 shown to be driven by information reliability, ambient risk and predator diversi ...

Assessing effects of predator density and diversity on neophobia in Trinidadian guppies

Author(s): Feyten LEA; Demers EEM; Ramnarine IW; Brown GE;

Neophobic predator avoidance, where prey actively avoid novel stimuli, is thought to allow prey to cope with the inability to predict predation risk (i.e. uncertainty) while reducing the costs associated with learning. Recent studies suggest that neophobia ...

Exploratory decisions of Trinidadian guppies when uncertain about predation risk

Author(s): Crane AL; Demers EE; Feyten LEA; Ramnarine IW; Brown GE;

Animals can reduce their uncertainty of predation risk by gathering new information via exploration behaviour. However, a decision to explore may also be costly due to increased predator exposure. Here, we found contextual effects of predation risk on the e ...
