| heterozygosity-fitness correlations in adult and juvenile zenaida dove, zenaida aurita. | 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 fo ... | 2012 | 23091225 |
| mode of foraging competition is related to tutor preference in zenaida aurita. | this study compared the direction of social learning in 2 populations of barbados zenaida doves (zenaida aurita). one population (st. james) is territorial; it competes aggressively with conspecifics but scramble competes with heterospecifics. the other population (deep water harbour) forages in large homospecific flocks. field observations were conducted to quantify intraspecific and interspecific patterns of foraging association and aggression. wild-caught doves from both areas were then teste ... | 1996 | 8851552 |
