Fine-scale genetic structure and parentage in Urocitellus beldingi
… burrow associated with that particular female. Paternity, however, can only be posited by observation of mating because the species exhibits multiple mating in both sexes, though not all matings necessarily result in offspring. Multiple paternity has been previously verified through allozyme …

Female preferences, paternity and fitness: A combined morphometric/molecular genetic study on Poecilia latipinna and Poecilia formosa
… preferred as well as with a non-preferred male, paternity was assigned via microsatellite analysis. Poecilia formosa females (N = 34) were mated with either a preferred or a non-preferred male. I found evidence that female preferences in both species did not depend on male size (a measure for …

Conserving Connectivity: Ecological Determinants of Gene Flow in Plants at the Landscape Scale
… correlated with fitness-related traits. Paternity analysis on a subset of seven populations revealed high rates of self-pollination. Within-population patterns of pollen flow correlated with floral resources measured at the scale of individuals and patches, whereas among-population pollen …

Sexual Selection in Mantled Howling Monkeys (Alouatta palliata), With an Emphasis on the Role of Female Mate Choice
… K. Glander to collect blood samples for genetic paternity analysis. A total of 29 individuals in the study group and eight adult males from surrounding groups were captured.</p><p>The genetic paternity analyses were largely inconclusive. Of the eight microsatellite markers used previously in this …

Fission-Fusion Dynamics in Spider Monkeys in Belize
… levels of within-group competition for females, paternity analysis revealed no reproductive skew, with all males siring offspring. Further analysis is needed to identify and understand the variables that are affecting the temporal changes in subgroup size, spatial cohesion, and stability of this …

Behavioral and genetic correlates of reproductive success in male addax (Addax nasomaculatus, De Blainville 1816)
… using both behavioral observations and genetic paternity analysis using microsatellites and the second exon of Adna DR3 of the major histocompatibility complex (MHC). There was a significant relationship between the age of the male and the number of offspring sired (rs =.46, N = 66, p = .0002) …

The Nature of Selection on Flowering Time: Integrating Fitness Contributions through Male and Female Function
A central goal of evolutionary biology is to identify traits under selection and the causal mechanisms linking these traits to fitness. Most work towards this goal in plant systems has addressed the female component of fitness only. This thesis investigates the nature of selection on the timing of …

Estudio de las pautas de reproducción de Quercus ilex L. y Q. suber L. mediante marcadores moleculares
… studies of gene flow, dispersal and parentage analysis. One of the transferred microsatellites resulted useful as a diagnosis marker between both species, enabling a rapid identification of hybrids. The spatial genetic structure was analyzed in a dehesa forest with natural regeneration, …
