Nesting Ecology of Hawksbill Sea Turtles (Eretmochelys imbricata) on Utila, Honduras
… presents the first description of hawksbill migration routes from Honduras, facilitating protection efforts for turtles that traverse international waters.</p>

The Effect of Area on Resource Competition among Migrant Birds at a Stopover Site
… requirements of migratory landbirds along migration routes. Habitat fragmentation may exacerbate the costs of migration by reducing food availability and/or increasing competition at crowded stopover sites. I predicted that smaller forest fragments would have higher densities of birds, and …

The Legality of Border Walls under International Law
… wall’s fragmentation of ecosystems and wildlife migration routes. The thesis concludes with an exploration of what a novel conceptualisation of State sovereignty, understood as a responsibility for the care of humankind, could imply for the legality of border walls under international law.

Stopover duration and habitat use of spring-migrating dabbling ducks in the Wabash River Valley, USA
Spring migration is an important and often under-studied period of the waterfowl annual cycle. Stopover sites along migration routes contain habitats and resources required by waterfowl to rest and refuel before continuing north to the breeding grounds. The Wabash River Valley (WRV) in southeastern …

Feast Your Eyes: An Exploration of Our Consumption of Whales
… reef systems, local communities, and whale migration routes. As the global discourse pivots towards innovative strategies for climate resilience, this research contributes to the ongoing dialogue by deepening our comprehension of human-nature dynamics. By acknowledging our role in shaping …

The Pareiasaur Elginia from Elgin, north east Scotland, and the late Permian extinction event
… An attempt is made to establish the migration routes of pareiasaurs, based on<br/>stratigraphic, fauna! and palaeogeographical data.<br/><br/>Only two specimens of Elginia are known. A restoration of the skull and skeleton of Elginia is attempted, based on the type skull, BGSE …

Nested clade analysis of geographic structure in the morphologically variable Themeda triandra in South Africa
… H10. It is thought that T. triandra followed two migration routes within South Africa: one along the coast, with the other inland above the escarpment where populations became genetically isolated from populations below the escarpment. Further studies may look for a correlation between …

Reduce the charge risking applying migration tracers
… post drill the focus is now on charge and migrations, as the proven source rock quantity and quality are in many cases proven. Current charge risking primarily relies on basin models built on geophysical, geological, geochemical source rock parameters. Geochemical post well analyses are …

Taxonomy and phytogeography of the Cactaceae of eastern Brazil
… support to recent hypotheses on historical plant migration routes in South America, while analysis of distribution patterns indicates > 94% of taxa as ± restricted to one of 3 major vegetation categories: (1) <i>Mata atlântica</i>, (2)<i> Caatingas</i> & Northern <i>campos rupestres</i>s and (3) …

Nuclear and cytoplasmic genetic variation in Picea: DNA markers for evaluating past migration, introgression and evolutionary history
… would enable paleoclimatologists to track the migration routes of the individual spruce species during the last ice age and infer more precise climate estimates for eastern North America. Agarose gel electrophoresis, Southern blot and hybridization suggested that authentically ancient DNA …

The role of fish physiology, behaviour, and water discharge on the attraction and passage of adult sockeye salmon (Oncorhynchus nerka) at the Seton River dam fishway, British Columbia
… dams have interrupted the connectivity of migration routes for fish. While fishways can provide access between downstream and upstream habitats, it is important that passage can occur with minimal delay, energy expenditure, and physiological stress. The research presented here is based on …

Study of T cell activation and migration at the single-cell and single-molecule level
… T cells alter their physical properties and migration routes upon activation, they may possess dissimilar mechanical properties as a result of this process. This hypothesis was tested using the techniques micropipette aspiration and atomic force microscopy, which allow the investigation of …

The Conservation Ecology of Rana temporaria and Bufo bufo in Leicestershire
… the origins of frog and toad pre-breeding migrations and subsequent terrestrial habitat to comprise scrub and woodland, water courses to be the main migration routes. Ingestion of radio transmitters proved not to impair the appetites or be injurious to frogs and toads. Transmitter implanted …

DISCRIMINATING OVERWINTERING ORIGIN AND MIGRATORY CONNECTIVITY IN A LONG-DISTANCE MIGRATORY SHOREBIRD STAGING IN THE CANADIAN PRAIRIES
… as they undertake impressive circumpolar migrations between breeding and overwintering areas. The ability to trace individual-level movements and assess the consequences of those decisions is critical as migratory connectivity is known to influence population demographics. I used both …

TRAYECTORIAS DEL EXILIO: LA IDENTIDAD CULTURAL REPUBLICANA EN LA LITERATURA DE MAX AUB Y DE MARÍA TERESA LEÓN
… phases of the convulsive trajectories of their migration routes. For both writers, France will be the first place of destination, but, in the case Aub, he will be indelibly marked by his experience in the French prisons and concentration camps. Continuing with the chronological development, …

Insects in mountainous landscapes: Implications of landscape context and climate change
… habitats are not available along their migration routes, insect habitat specialists may not be able to successfully follow shifting climatic envelopes. In this thesis I addressed four intertwined questions: What are the resource requirements — habitat area, quality and fragmentation — …

MOVING THE GOALPOSTS: MIGRATORY BIRDS IN A CHANGING WORLD
… two understudied phases of the annual cycle: migration and the non-breeding stationary period. In Chapter 1, I explore how human activities may nonlethally affect birds during migration. I reviewed the scientific literature for evidence of nonlethal effects and of interacting threats that may …

ENDURING SOLIDARITIES. SPACES, PRACTICES, AND RELATIONS OF MIGRANT SUPPORT ALONG THE BALKAN ROUTES.
… grassroots solidarity practices along the Balkan migration routes in the context of increasingly restrictive European border regimes. Focusing on Greece, Bulgaria, and Bosnia and Herzegovina, the study investigates how bordering processes shape migrants’ trajectories and lived experiences, and how …
