Early-life and parental predation risk shape fear acquisition in adult minnows.

Author(s): Crane AL, Meuthen D, Thapa H, Ferrari MCO, Brown GE

Exposure to predation risk can induce a fearful baseline state, as well as fear reactions toward novel situations (i.e., neophobia). Some research indicates that risk exposure during sensitive periods makes adults more prone to acquiring long-term fearful p...

Exploring the threat-sensitive predator avoidance hypothesis on mate competition in two wild populations of Trinidadian guppies.

Author(s): Chuard PJC, Grant JWA, Ramnarine IW, Brown GE

The intensity of mate competition is often influenced by predation pressure. The threat-sensitive predator avoidance hypothesis predicts that prey should precisely adjust their fitness-related activities to the level of perceived acute predation risk and th...

Abstract

Teleost fish are neuroplastic and are known to alter their brain morphology and behavior in response to environmental change such as an increase in predation pressure. The hypothalamus plays a key role in regulating behavioural responses to predation risk. In our study, wild-caught northern red bellied dace (Chrosomus eos) developed smaller and less symmetric hypothalami when held in captivity for fourteen days; both measures correlated with boldness in a latency to emerge test. Our results highlight the potential impact of short-term holding conditions on brains and behaviour. This article is protected by copyright. All rights reserved.
