Impacts of group selection harvest openings on the reproductive success of the Solitary Vireo (Vireo solitarius alticola)
… using the group selection method in 1995. Pairing success was 88% on the unharvested site in 1994, however it was lower on the harvested sites in 1995 (53.8%). Low reproductive success was observed in both years (12% and 22% respectively). In 1995, the amount of opening within a 200 meter …

Mechanisms underlying population dynamics of a migratory songbird in a fragmented forest
… attributed to fragment size and isolation (low pairing success, area sensitivity, unstable population sizes). I studied the impact of Brown-headed Cowbird (Molothrus ater) brood parasitism and of nest predation on the reproductive success of Wood Thrush (Hylocichla mustelina) hosts in three …

Evolutionary and conservation genetics of the Seychelles warbler (Acrocephalus sechellensis)
… age and heterozygosity, but not MHC, predicted pairing success. Lastly, I investigated survival and reproductive consequences of Ase-ua4, an MHC class I allele previously shown to confer a survival advantage in the Seychelles warbler. I found widespread patterns of allele frequency increase …

Factors influencing parasite-related supression of mating behavior in the isopod caecidotea intermedius
… parasites have been shown to have reduced pairing success in nature. Additionally, it has been shown that male mating responsiveness (e.g. willingness to mate) is reversible (from no mating attempts to positive mating attempts). However, little is known about the potential ultimate and …

Population Ecology and Foraging Behavior of Breeding Birds in Bottomland Hardwood Forests of the Lower Roanoke River
… the lower Roanoke River, North Carolina. Nesting success was monitored in two forest width classes: narrow bands of levee forest that were dominated by two edge types, and wide, continuous levee forest stands that have edges but most forest is relatively far from edge. Nest success of Acadian …
