It's about time: the temporal dynamics of phenotypic selection in the wild.
A database of temporal replicates of selection from studies of wild populations is assembled to synthesize what the authors do (and do not) know about the temporal dynamics of selection. Expand
Physiological Causes and Consequences of Social Status in Salmonid Fish1
Abstract Social interactions in small groups of juvenile rainbow trout (Oncorhynchus mykiss) lead to the formation of dominance hierarchies. Dominant fish hold better positions in the environment,Expand
The effects of cortisol administration on social status and brain monoaminergic activity in rainbow trout Oncorhynchus mykiss
The results suggest that the effects of cortisol on social status in rainbow trout may be mediated via the modulation of central signaling systems and subsequent changes in behaviour and/or competitive ability, although the exact site of action in the brain remains uncertain. Expand
Ecosystem biomonitoring with eDNA: metabarcoding across the tree of life in a tropical marine environment
The potential of eDNA to inform on the breadth of biodiversity present in a tropical marine environment is investigated, and the sensitivity and low cost of e DNA metabarcoding are advocated, urging this approach to be rapidly integrated into biomonitoring programs. Expand
The spatial patterns of directional phenotypic selection.
It is found that selection tends to vary mainly in strength and less in direction among populations, which may limit the potential for ongoing adaptive population divergence. Expand
Patterns of genetic variation in anthropogenically impacted populations
It is found that human disturbances are associated with weak, but consistent changes in neutral genetic variation within natural populations, with particular attention paid to the effects of habitat fragmentation. Expand
Long‐term natal site‐fidelity by immature lemon sharks (Negaprion brevirostris) at a subtropical island
It is shown that many island‐born lemon sharks remain close to their natal area for long periods (years) after leaving the nursery; more than half of the sampled sharks up to 135 cm total length (∼6 years old) were locally born. Expand
Precipitation drives global variation in natural selection
It is reported that aspects of precipitation and potential evapotranspiration, along with the North Atlantic Oscillation, predicted variation in selection across plant and animal populations throughout many terrestrial biomes, whereas temperature explained little variation. Expand
After continents divide: comparative phylogeography of reef fishes from the Red Sea and Indian Ocean
The Red Sea is an evolutionary incubator, occasionally contributing species to the adjacent Indian Ocean, and elevated endemism and species export indicate a need for enhanced conservation priorities for the Red Sea. Expand
When bigger is not better: selection against large size, high condition and fast growth in juvenile lemon sharks
It is suggested that selective pressures at Bimini may be constraining the evolution of large size and fast growth, an observation that fits well with the observed small size and low growth rate of juveniles at this site. Expand
