Journal ArticleDOI
Understanding and confronting species uncertainty in biology and conservation
TL;DR: It is argued that biologists who endure the species problem can benefit from a synthesis in which individual taxonomic species are used as hypotheses of evolutionary entities, and that biological research on species will benefit from an explicit recognition of the inherent limitations that biologists experience as investigators of species.
Journal ArticleDOI
Shoal choice in zebrafish, Danio rerio: the influence of shoal size and activity
TL;DR: The influence of shoal activity on shoal size preference in the zebrafish is investigated and it is found that test fish generally preferred the larger shoal, however, this preference could be reduced by presenting the larger Shoal in colder water and so reducing its activity.
Journal ArticleDOI
The social organization of fish shoals: a test of the predictive power of laboratory experiments for the field
TL;DR: Predictions based on experiments in captivity regarding p for conspecifics, individuals of similar body length and unparasitized fish were highly consistent with field observations on free‐ranging shoals whereas p for familiar conspecies and kin remain to be conclusively demonstrated in the field.
Journal ArticleDOI
Evolution of sex: The costs and benefits of sex: new insights from old asexual lineages
TL;DR: Exciting new results on ancient asexual organisms show that lineages can persist for many millions of generations without recombination, and understanding how they do so might well provide crucial new insights into the problem of sex.
Journal ArticleDOI
QTL Analysis of Behavioral and Morphological Differentiation Between Wild and Laboratory Zebrafish ( Danio rerio )
TL;DR: The results indicate the existence of QTL for boldness on chromosomes 9 and 16 and suggest another genomic region that influences anti-predator behaviour on chromosome 21 and confirm the potential for QTL mapping of behavioural traits in zebrafish.
