Alternative Responses to Predation in Two Headwater Stream Minnows Is Reflected in Their Contrasting Diel Activity Patterns
TLDR
Diurnal activity patterns for redfin minnows may explain their susceptibility to high predation by visual non-native piscivores, such as bass and trout, and the nocturnal habits of chubbyhead barbs suggest a probable pre-adaptation to visual predation.
Habitat type and schooling interactively determine refuge-seeking behavior in a coral reef fish throughout ontogeny
TLDR
The results demonstrate that although H. flavolineatum makes multiple shifts in habitat throughout its life cycle, in the absence of other bio- logical or environmental drivers preference for shelter habitat past the early post-settlement stage remains the same.
Ontogenetic shifts in social aggregation and habitat use in a temperate reef fish
Cover, both from physical structure or association with social groups, can reduce predation risk and increase foraging, leading to enhanced growth and survival, and is therefore a critical aspect of
Microhabitat complexity influences fear acquisition in fathead minnows
TLDR
For minnows, low microhabitat complexity appears to lead to elevated fear, which remains even after a habitat change, and is observed in the novel habitat, where background risk in both simple and complex habitats caused neophobia.
Do furtive predators benefit from a selfish herd effect by living within their prey colony?
TLDR
It is concluded that A. aphidimyza preferentially choose the central position of their aphid prey colonies, which reduces the probability of becoming the first prey attacked by intraguild predators.
Trait-mediated effects of predation risk: How does it influence forest bird-habitat relationships?
TLDR
It was found that increased perception of predation risk tended to negatively affect the abundance, occurrence and / or detection probability of most prey forest birds in ways generally explainable by body size, and largely reduced community species richness and shifted community composition.
Predator experience homogenizes consistent individual differences in predator avoidance
TLDR
The results suggest that consistent individual differences in risk-taking behavior (also referred to as the personality trait ‘boldness’) are modified by predator exposure and learning about predators.
Performance level and efficiency of two differing predator-avoidance strategies depend on nutritional state of the prey fish
TLDR
The experiment confirmed the plasticity of the anti-predator behaviour in roach and demonstrated that food deprivation diminished the efficiency of shoaling more strongly than the efficiencyof hiding.
Effects of habitat complexity on mating behavior and mating success in a marine fish
TLDR
It is indicated that habitat complexity affects mating behaviors of both females and males and that a more structurally complex habitat might relax sexual selection.

TLDR
Mnows from provenances with and without pike exhibited a similar repertoire of antipredator behaviour patterns, but those sympatric with the predator integrated their tactics more effectively and regained pre-exposure behaviour sooner after each encounter.
Size-segregative behaviour in minnow shoals
TLDR
The experiment shows that asymmetrical pay-offs in foraging and in response to predator threat are the probable reasons for size-segregation behaviours, and supports the views of earlier workers that mechanical sorting by swimming speed is not an important factor in size segregation in shoals.
Dicing with death: predator inspection behaviour in minnow shoals
TLDR
Individual minnows which have carried out an inspection visit to the predator model exhibit changes in behaviour on return which are contingent upon the state of the model, demonstrating that information is gained.
Flocking is an effective anti-predation strategy in redshanks, Tringa totanus
. Anti-predator behaviour in overwintering redshanks on an estuary in south-east Scotland was studied in the context of a very high mortality rate due almost entirely to predation by raptors. Attacks
The social organization of free‐ranging fish shoals
TLDR
No evidence was found that shoals might break up into sub-units of individuals that are more phenotypically assorted than their original shoals, and the mechanisms by which assortative groups may arise and the consequences of low group fidelity for the evolution of cooperative behaviour are discussed.
An experimental test of the costs of antipredatory refuge use in the wall lizard, Podarcis muralis
TLDR
It is suggested that an increase in the time spent in refuges at unfavourable temperatures during the experiment led to a loss of time available for foraging and a diminution of the efficiency of physiological functions, which resulted in loss of mass.

TLDR
This report presents a new source of evidence favoring an antipredator role for schooling in guppies from natural populations of a small tropical freshwater fish, the guppy, in the Northern Range Mountains of Trinidad, West Indies.
The Dynamics of Prey Refuge Use: A Model and Tests with Sunfish and Salamander Larvae
TLDR
A simple dynamic model of refuge use is developed that predicts patterns over time for prey survival and for the proportion of prey in refuge and the apparent paradox of a high predation rate when few prey are exposed could be easily understood only in terms of the dynamics of Refuge use.
Learned recognition of conspecifics by fishes
The study of partner-choice decisions of individual fish is a good way in which insights into patterns of school structure or territorial assemblages can be gained. Most initial work has focused on

TLDR
Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research.
