Female extrapair mating behavior can evolve via indirect selection on males
In many species that form socially monogamous pair bonds, a considerable proportion of the offspring is sired by extrapair males. This observation has remained a puzzle for evolutionary biologists:Expand

Inbreeding depression of sexually selected traits and attractiveness in the zebra finch
An underexploited approach to study condition dependence of sexually selected ornaments is to use inbreeding to manipulate individual genetic quality. Because of differences in genetic architecture,Expand

MECHANISMS OF POPULATION DIFFERENTIATION IN MARBLED MURRELETS: HISTORICAL VERSUS CONTEMPORARY PROCESSES
Abstract.— Mechanisms of population differentiation in highly vagile species such as seabirds are poorly understood. Previous studies of marbled murrelets (Brachyramphus marmoratus; Charadriiformes:Expand

Genetic and ecological data provide incongruent interpretations of population structure and dispersal in naturally subdivided populations of white‐tailed ptarmigan (Lagopus leucura)
The dispersal of individuals among populations affects the demographic and adaptive trajectories of animal populations and is fundamental to understanding population dynamics. White‐tailed ptarmiganExpand

Presence of Campylobacter and Salmonella in sand from bathing beaches.
The purpose of this study was to determine the presence of thermophilic Campylobacter spp. and Salmonella spp. in sand from non-EEC standard and EEC standard designated beaches in different locationsExpand

A sex-chromosome inversion causes strong overdominance for sperm traits that affect siring success
Male reproductive success depends on the competitive ability of sperm to fertilize the ova, which should lead to strong selection on sperm characteristics. This raises the question of how heritableExpand

Basal metabolic rate can evolve independently of morphological and behavioural traits
Quantitative genetic analyses of basal metabolic rate (BMR) can inform us about the evolvability of the trait by providing estimates of heritability, and also of genetic correlations with otherExpand

Irreproducible text‐book “knowledge”: The effects of color bands on zebra finch fitness
Many fields of science—including behavioral ecology—currently experience a heated debate about the extent to which publication bias against null findings results in a misrepresentative scientificExpand

Plumage color manipulation has no effect on social dominance or fitness in zebra finches
Many species of birds have evolved a colorful plumage, and such ornamentation is thought to play a role in mate choice and in social dominance interactions. Here, we study captive zebra finches thatExpand

Proximate causes of infertility and embryo mortality in captive zebra finches
Some species show high rates of reproductive failure, which is puzzling because natural selection works against such failure in every generation. Hatching failure is common in both captive and wildExpand
