A rare observation of a male Lesser Antillean Bullfinch (Loxigilla noctis) on Barbados.
2013
4 pages; International audience; We report the observation of a male Lesser Antillean Bullfinch (Loxigilla noctis) on the island of Barbados from 24 May to 12 June 2010, only the third record for this species on Barbados. We discuss the relevance of this observation to the taxonomic status of the Barbados Bullfinch (L. barbadensis) and the evolutionary loss of sexual dichromatism.
Heterozygosity-fitness correlations in adult and juvenile Zenaida Dove, Zenaida aurita.
2013
10 pages; International audience; Understanding how fitness is related to genetic variation is of crucial importance in both evolutionary ecology and conservation biology. We report a study of heterozygosity-fitness correlations in a wild, noninbred population of Zenaida Doves, Zenaida aurita, based on a sample comprising 489 individuals (382 adults and 107 juveniles) typed at 13 microsatellite loci, resulting in a data set comprising 5793 genotypes. In both adults and juveniles, and irrespective of sex, no evidence was found for an effect of either multilocus or single-locus heterozygosity on traits potentially related to fitness such as foraging tactic, competitive ability, and fluctuatin…
