Heritability of Boldness and Aggressiveness in the Zebrafish
Behavioural traits that are consistent over time and in different contexts are often referred to as personality traits. These traits influence fitness because they play a major role in foraging,Expand

The effect of variation in boldness and aggressiveness on the reproductive success of zebrafish
Boldness and aggressiveness are two behavioural traits that have received extensive attention in the field of animal behaviour. However, relatively little is known about how these traits areExpand

Do male guppies distinguish virgin females from recently mated ones?
In some mating systems males should benefit from mating with virgin females because of their higher reproductive value. We determined experimentally whether and how males distinguish between virginExpand

Strategic egg allocation in the zebra fish, Danio rerio
Females across a range of taxa have been shown to differentially allocate their reproductive resources according to the attractiveness of their mate. Previous studies demonstrated a female preferenceExpand

Adaptive variation in sex determination in a crustacean, Gammarus duebeni
In some animals sex is determined after conception by environmental factors (environmental sex determination. ESD). In the amphipod Gammarus duebeni sex is reportedly determined by photoperiod: thereExpand

Aggression and sex differences in lateralization in the zebrafish
Aggression plays an important role in survival and reproduction. It can be measured using mirror and dyadic tests, but there is some debate about whether interactions with a mirror image and with aExpand

Phenotypic correlates of spermatozoon quality in the guppy, Poecilia reticulata
The phenotype-linked fertility hypothesis suggests that a female can benefit directly from mate choice when the cues she uses indicate the quantity and/or quality of his spermatozoa. We tested theExpand

Toad tadpole aggregation behaviour: evidence for a predator avoidance function
Two sets of experiments were conducted to determine whether aggregation behaviour, commonly observed in tadpoles of the common toad, Bufo bufohad a predator avoidance function. In the first set ofExpand

Female association preferences based on olfactory cues in the guppy, Poecilia reticulata
Guppies are highly sexually dimorphic. Females have been shown to mate preferentially with males with various visible traits and previous studies investigating mate choice have focussed on theseExpand

Disassortative mating for boldness decreases reproductive success in the guppy
Consistent individual differences in personality or temperament have been observed in many animal taxa, and one particular trait, boldness, has been studied extensively. Most studies on mate choiceExpand
