Migratory Behavior and Survival of Adult Female Elk in a Partially Migratory Population
<p>Within a migratory species, individuals that migrate are expected to enhance lifetime fitness through exposure to higher quality forage and avoiding predation to a greater degree than non-migratory conspecifics. Partial migration occurs when a portion of the population migrates and the other …

Magnetic orientation in migratory birds
Wie nehmen Zugvögel das Magnetfeld wahr und wie nutzen sie diese Information, um sich zur Zugzeit zu orientieren? Das sind die Schlüsselfragen meiner Doktorarbeit. Cryptochrome werden als potentielle Magnetfeld-Rezeptoren vorgeschlagen. Ich konnte vier Cryptochrom-Varianten in der Retina von …

Migratory Ecology of Sea Turtles
… This is especially true for migratory species, such as sea turtles, whose long-distance movements form a major component of their life history. In this thesis, I investigated which factors are driving the migratory behavior of the leatherback turtle<em>Dermochelys coriacea. …

DISCRIMINATING OVERWINTERING ORIGIN AND MIGRATORY CONNECTIVITY IN A LONG-DISTANCE MIGRATORY SHOREBIRD STAGING IN THE CANADIAN PRAIRIES
Migratory birds are experiencing widespread global declines. Shorebirds appear to be experiencing some of the most dramatic declining population trends, with the long-distance, Arctic-breeding migrants apparently losing ground the fastest. Challenges arise in monitoring these populations as they …

Gut Microbiota of Migratory Passerines at Stopover
… gut microbes are especially important during the migratory phase; however gut atrophy experienced during prolonged migratory flight may cause disruptions of the stable microbiota. Fecal samples were collected from several species of passerine after crossing the Gulf of Mexico during spring …

Intertidal mudflats and the conservation of migratory shorebirds
Migratory shorebirds rely on intertidal habitats that are increasingly threatened by habitat loss, human disturbance, and climate change. Investigating habitat availability, its influence on shorebird populations and how to prioritise conservation efforts is critical to inform conservation …

Large-scale habitat relationships of neotropical migratory birds
I examined the relationship of bird assemblages and species to habitat patterns over landscapes composed of a mosaic of habitat elements. I surveyed songbirds using a variation of the variable circular plot method during the 1994 and 1995 breeding seasons on 20 sites ranging in size from 50 to 72 …

Long-distance navigation and magnetosensory mechanisms in migratory songbirds
Ungeachtet vieler wissenschaftlicher Erkentnissgewinne im Bereich der Orientierungs und Navigationsmechanismen von Zugvögeln während ihrer Migrationen, verbleiben diesbezüglich viele Fragen unbeantwortet. Im Rahmen meiner sieben Publikationen umfassenden Doktorarbeit, habe ich hauptsächlich …

MOVING THE GOALPOSTS: MIGRATORY BIRDS IN A CHANGING WORLD
Billions of birds undertake migratory movements each year, traveling distances that range from several hundreds to tens of thousands of kilometers. Migratory birds must be flexible enough to cope with the fluctuating conditions they encounter during these journeys and at their destinations. …

Selection of Overwintering Microclimate by Migratory Western Monarch Butterflies
<p>Migratory species are expected to demonstrate habitat selection that occurs at multiple spatial and temporal scales. Western monarch butterflies migrate seasonally to overwinter in groves at geographically predictable locations along the California coast. To date, overwintering habitat selection …
