Olfactory cues of risk and visual cues of safety interact with sympatry and phylogeny in shaping behavioral responses by littoral fishes

BD Wisenden, AA Andebrhan, CM Anderson… - Behavioral Ecology and …, 2023 - Springer
Prey incorporate information about risk, safety, and the reliability of both of these cues when
assessing risk of predation. Here, we report results of an experiment testing avoidance of …

Synergistic interactions between chemical alarm cues and the presence of conspecific and heterospecific fish shoals

BD Wisenden, MS Pollock, RJ Tremaine… - Behavioral Ecology and …, 2003 - Springer
Chemical and visual sources of information are used by aquatic prey during risk
assessment. Here, we test the behavioral response of littoral prey fish to combinations of …

Baseline activity and shoal type determine antipredator behaviors in bluegill from a southern Ontario lake

JI Lloren, SM Davidson, WM Twardek… - Behavioral Ecology and …, 2019 - Springer
Shoaling is an evolved behavior in fishes that has several adaptive advantages, including

When is it safe to go home? Post-predation assessment of risk and safety when personal information conflicts with social cues

BD Wisenden, CM Adkins, SA Campbell… - Behavioral Ecology and …, 2024 - Springer
Navigating risk of predation is a major driver of behavioral decision-making in small fishes.
Fish use personal information from olfactory and visual indicators of risk, and also rely upon …

Assessment of local predation risk: the role of subthreshold concentrations of chemical alarm cues

GE Brown, JF Poirier, JC Adrian Jr - Behavioral Ecology, 2004 - academic.oup.com
The ability to accurately assess local predation risk is critical to prey individuals, as it allows
them to maximize threat-sensitive trade-offs between predator avoidance and other fitness …

Is there a fish alarm cue? Affirming evidence from a wild study

BD Wisenden, KA Vollbrecht, JL Brown - Animal Behaviour, 2004 - Elsevier
Chemical alarm cues released from injured tissue are not released under any other context
and therefore reliably inform nearby prey of the presence of a predator. Laboratory and field …

Learning about danger: chemical alarm cues and local risk assessment in prey fishes

GE Brown - Fish and Fisheries, 2003 - Wiley Online Library
An individual's behaviour patterns can be conceptualized as a series of threat‐sensitive
trade‐offs between ambient predation pressure and a suite of fitness‐related activities, such …

Social context influences the antipredator behaviour of fathead minnows to chemical alarm cues

MS Pollock, RJ Pollock, DP Chivers - Ethology, 2006 - Wiley Online Library
Prey fishes, like many organisms under fluctuating predation threat, rely on multiple sources
of information to accurately gauge current risk. This includes the use of chemical cues such …

Testing the threat‐sensitive hypothesis with predator familiarity and dietary specificity

BA Crawford, CR Hickman, TM Luhring - Ethology, 2012 - Wiley Online Library
In a system with multiple predators, the threat‐sensitive predator avoidance hypothesis
