Incubation behavior and dispersal patterns in the Mountain Plover (Charadrius montanus)
… to examine sex differences in natal and breeding dispersal. I used nest locations from a breeding population of plovers in north-central Montana over a 13-year period (1995-2007) to examine patterns of sex bias in their dispersal. Additionally, I looked at the influence of prior …

White storks (Ciconia ciconia) of Eastern Germany: age-dependent breeding ability, and age- and density-dependent effects on dispersal behavior
Dispersal behavior plays an important role for the geographical distribution and population structure of any given species. Individual’s fitness, reproductive and competitive ability, and dispersal behavior can be determined by the age of the individual. Age-dependent as well as density-dependent …

Female Dispersal and Inbreeding in the Red-cockaded Woodpecker
Dispersal is a critical life-history component; it determines gene flow and has profound effects on population structure, demography, social systems, and population viability. To add to our knowledge of dispersal and, in particular, our understanding of the relationship between dispersal and …

Determinants of variation in productivity, adult survival and recruitment in a declining migrant bird : the Whinchat (Saxicola rubetra)
… over the last few decades. Habitat change on the breeding grounds, especially agricultural intensification, is thought to be the main driver of the decline in Whinchats. However, recent evidence also suggests that the decline may have a common source, such as low over-winter survival, which …

Habitat, abundance and productivity of the Asian Houbara Chlamydotis macqueenii in Uzbekistan
… such as population reinforcement through captive breeding, it is important to explore potential in situ measures that could be used to mitigate species off-take by supporting breeding productivity of wild populations. Asian houbara Chlamydotis macqueenii is a globally threatened bird, with …

African penguin (Spheniscus demersus) distribution during the non-breeding season : preparation for, and recovery from, a moulting fast
… of the endangered African penguin during the non-breeding season. As foraging success during this period is critical to adult survival, this project explores their dispersal patterns, as well as the degree of overlap with commercial purse-seine fisheries which target the same prey. African …

Population demography of lark buntings: post-fledging survival, fecundity, and breeding decisions
… productivity and juvenile survival on the breeding grounds are among the possibilities. To assess population declines, direct and reliable estimates of survival, fecundity, and dispersal are required. Consequently, I estimated demographic parameters (i.e., post-fledging survival and …

Population Dynamics of Willow Flycatchers in the Sierra Nevada
… a low-density population of Willow Flycatchers breeding in the central Sierra Nevada from 1997-2008. Beginning in 2003 I also monitored two higher density flycatcher populations in the north Sierra Nevada to provide comparative estimates of reproductive performance. I grouped study sites into …

Connections between individual dispersal behavior and the multi-scale distribution of a saproxylic beetle
… study relating individual behavior (dispersal, habitat selection, and intra-specific interactions) with hierarchically-organized environmental filters to predict the incidence of Odontotaenius disjunctus (Passalidae), a saproxylic (=decayed wood dependent) beetle common to eastern …

Population Dynamics and Dispersal Coalitions in the Cooperatively Breeding Acorn Woodpecker
<p>Dispersal is a critical life-stage with consequences not only for the individual, but for population dynamics and thus the fate of the whole species. The creation of dispersal coalitions can lead to complex outcomes and affect how changes in abundance occur on the landscape. I examined …
