Migration and moult strategy of the curlew sandpiper
… Curlew Sandpiper in relation to the different migratory routes and non-breeding areas of the species, focusing on the carry-over effects which conditions at the breeding grounds have on the timing of post-breeding migration and, subsequently, on the timing of moult at the non-breeding areas. …

Movement Ecology and Conservation of the Migratory Bats Lasiurus cinereus and Lasionycteris noctivagans
… about bat migration, but recently, fatalities of migratory bats at wind energy facilities across North America have offered the opportunity to gain insight into migratory-bat behaviour. Using a combination of stable-isotope and genetic analyses, I studied patterns of movement and relatedness of …

Evaluation of rural land-use plans in protected area bio-networks in northeastern Tanzania
… and enhancing conservation of important wildlife migratory routes. Nine villages were selected for study in Northeastern Tanzanian rangelands, within the Tarangire-Manyara, Greater Serengeti and MkomaziTsavo ecosystems. Several methods were used to provide an indication of the performance of the …

Assessment of environmental and anthropogenic factors that affect movement of sedentary blue wildebeest (Connochaetes taurinus) in the Kalahari region of Botswana
… Kalahari wildlife had historically relied on migratory routes that facilitated access to vital water sources during seasonal extremes. Under the 1975 Tribal Grazing Land Policy (TGLP) in Botswana, ungulates, such as the blue wildebeest (Connochaetes taurinus), have lost access to these …

The genetics and movement of ecologically important migratory Hoverflies
… to that of bee species, and discussing their migratory propensity. Next follows a study of the role of migratory hoverflies as long-distance pollen vectors, addressing key questions relating to pollen diversity and plant visitation networks, along with new insights into the migratory routes …

Chromosomal inversions as a mechanism for sympatric differentiation in common quails
… (AA, AB, BB) that differ in morphology and migratory 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 …

A Map of Transcription Factor Expression in Neuronal Precursors of the Chicken and Mouse Embryonic Cerebellum
… is well-studied, the specification and early migratory routes of cerebellar nuclei neurons and Purkinje cells are not well understood. To map neural progenitor identity, we analyzed the expression of various members of the TALE, LIM and bHLH transcription factor families in the avian and …

The Role of Avifauna in Paleodiet Reconstruction : An Arctic Case Study
… Arctic contexts as a case study. In the Arctic, migratory birds and their eggs have been important seasonal resources for hunter-gatherer populations, and while evidence of their utilization in the faunal record is apparent, their use is less clear from the isotopic record. Zooarchaeological …
