What should we weigh to estimate heterozygosity, alleles or loci?
Under a wide range of simulated scenarios, this index (HL) correlated better than both IR and uncorrected homozygosity (HO), measured as proportion of homozygous loci) with genome‐wide heterozygosity and inbreeding coefficients in open populations. Expand
Seasonal variation in sex ratio and sexual egg dimorphism favouring daughters in first clutches of the spotless starling
A seasonal shift in sex ratio from daughters to sons as the season advances is found and eggs containing female embryos are significantly heavier than those containing males in spite of the slight sexual dimorphism in favour of males. Expand
Experimentally increased testosterone affects social rank and primary sex ratio in the spotless starling
The results suggest that added testosterone had a direct role on the acquisition and maintenance of high social rank in female spotless starlings before egg formation and the maintenance of sex ratio differences long after having being implanted. Expand
Egg production and individual genetic diversity in lesser kestrels
Fecundity is an important component of individual fitness and has major consequences on population dynamics. Despite this, the influence of individual genetic variability on egg production traits isExpand
Sexual dimorphism in house sparrow eggs
It is demonstrated that house sparrow eggs containing male embryos are significantly larger than those containing female embryos, and this result provides further evidence of the ability of females to detect or control ovulation of either male or female ova and to differentially invest in one sex over the other.

Characteristics of loci and individuals are associated with germline microsatellite mutation rates in lesser kestrels (Falco naumanni).
The results do not support the male-biased mutation rate described in other organisms and suggest that mutation dynamics at microsatellite loci are a complex process which requires further research. Expand
Morphological Adaptation with No Mitochondrial DNA Differentiation in the Coastal Plain Swamp Sparrow
A rapid and recent geographic expansion of Swamp Sparrows from restricted Pleistocene populations is suggested, suggesting that selection on the divergent traits is intense. Expand
Temporal variation of heterozygosity‐based assortative mating and related benefits in a lesser kestrel population
The results offer empirical support to the heterozygous mate hypothesis of sexual selection but suggest that genetic diversity may act as a temporally variable target for mate choice. Expand
Individual genetic diversity correlates with the size and spatial isolation of natal colonies in a bird metapopulation
Evidence is provided of the association between individual heterozygosity and the size and spatial isolation of natal colonies in a highly mobile vertebrate showing relatively frequent dispersal and low genetic differentiation among local subpopulations. Expand
