Possible Role Of Breeding Phenology, Brood Size, And Male Parental Care On The Number Of Nesting Attempts By Female Eastern Bluebirds, A Facultatively Multibrooded Species
… attempt to raise two or more broods in a single breeding season. The results of previous studies have revealed much variation among species in the factors that influence the likelihood of female songbirds attempting to raise multiple broods during a breeding season. As such, additional studies …

The population biology of Ligia oceanica (L.)(Crustacea: Oniscoidea)
… years. Sex ratio, size at maturity, growth, breeding phenology, size and age structure, population density and size, female breeding size, fecundity regression and broodpouch mortality have been determined. From these data population natality, and schedules of survivorship, fecundity and …

Genetic diversity and distribution of the ringed salamander (Ambystoma annulatum) across multiple spatial scales
… flow for A. annulatum and A. opacum, two fall breeding species, as compared to two spring breeding species (A. maculatum and N. v. louisianensis) across the same focal landscape. Across all four species, I identified marginal support for landscape resistances describing gene flow better than …

Chromosomal inversions as a mechanism for sympatric differentiation in common quails
… behaviour while still coexisting and interbreeding in parts of the western Palearctic. This thesis assess how this rearrangement shapes population processes and contributes to divergence in sympatry. In Chapter 1, quails wintering in southern Iberia are analysed to determine the genetic …
