An avian embryo is ectothermic, with body temperature determined by environmental temperature. Upon hatching, the neonate begins a conversion so that endothermic capacity becomes feasible and body temperature becomes independent of environment. Whole animal metabolic rate and ventilation response, cardiovascular development, and maturation of muscle mitochondrial flux were the focus of this dissertation because of the direct role in shivering thermogenesis.

Because of the scarcity of information for bird communities at the major mainland rivers of southeastern Alaska, the main objective of this study was to provide baseline information including distribution, status, and habitat associations of breeding birds. I conducted a meta-analysis of all known reports (including the current study) conducted at major mainland rivers during the breeding season. I described bird species composition, distribution, abundance estimates, status, habitat associations, and guild membership for all birds recorded at 11 major mainland rivers.

The ability to accurately identify individuals is required for the detailed study of animals. Numerous artificial markers have been developed for this purpose.

In light of the known and potential deleterious effects of marking, attention has been focused on developing new techniques to identify individual raptors without attaching artificial markers.<

Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>The interaction between frugivorous birds and plants is one of the most important mutualisms in tropical regions. However, the way these groups interact varies according to temporal availability of fruit. In seasonal sites, it is expected that a specialization in a particular type of fruit is not viable, because this feature is not available throughout the year, and species that occupy these sites have a broad trophic niche. With a more stable supply of resources, a greater level of specialization is expected, which would be refl

The winter period is typically associated with harsh weather conditions and reduced food availability, which may lead to increased mortality. In birds, a common strategy to avoid such risks is to migrate to more favourable grounds, but its demographic costs are largely unknown. The wintering season remains a black box in our knowledge of the life cycle of birds. From the perspective of a wintering area, I study the population ecology of a migratory species, based on the hypothesis that winter aggregations of birds constitute true populations, instead of random aggregations of individuals.

Grouse chicks are known to eat ticks as part of their diet in the first three weeks of life which may contribute to virus persistence if chicks consume infected ticks.

Sagebrush shrubsteppe ecosystems have increasingly garnered attention as an endangered ecosystem.

Most of the research on sagebrush ecosystems has been conducted at lower elevations and in large expanses of sagebrush. A considerable amount of sagebrush is found at higher elevations, often in meadows found within a forest matrix. The role of this high-elevation habitat is poorly understood.

Many animals socially learn, but very few do so through teaching, where an individual modifies its behaviour in order to facilitate learning for another individual.

In many putative cases of teaching, it is not known whether the pupil learns from the modified behaviour. This thesis addresses this issue in three cases of potential teaching behaviour. In particular, it investigates whether the role of food transfers in wild golden lion

Pursuit behaviours are vital in predator-prey interactions and in courtship for many flying animals. Existing research on target-directed flight behaviours in insects, birds and bats has aimed at identifying simple geometric rules describing the pursuit-flight trajectories. However, these geometric rules are only part of the picture as they only consider the outcome of the commanded changes in flight kinematics, and not the underlying guidance laws (dynamics) which generate these commands. To intercept a target, a pursuer implements a guidance law using sensory feedback to determine the requir

Seed dispersal in New Zealand relies on a different guild from the one present before the arrival of humans into the islands. Post-dispersal biotic and abiotic filters have also changed due to the introduction of seed predators and herbivores. The aim of this thesis was to evaluate the actual contribution of seed dispersers to the patterns of seed fall and to understand the effects of biotic (seed density, predators, distance from conspecifics) and abiotic (pH, canopy openess, etc) factors on seed and seedling survival. I expected that tree species with different fruit sizes would be selected

Voltaire wrote "With great power comes responsibility", a quote which can easily be applied to scientists nowadays whose work effectively shapes the life of billions of living beings, operating through various disciplines from medicine through to ecology. To help scientists working with wild creatures, animal-attached electronic devices, commonly referred to as 'tags', have become indispensable tools, pushing the boundaries into the unimaginable enabling, for instance, information to be sent from animals into space and back via satellites. This 'great power' does indeed come with 'responsibili

The kea is the only parrot species in the world to include the true alpine environment as part of their habitat. Survival in these harsh alpine conditions has been hypothesised to be the cause of the generalist behaviour of kea, leading to their heightened explorative behaviour and curiosity. Kea are also widely regarded as being extraordinarily intelligent. It is their intelligence that suggests that kea may possess a sophisticated communication system. I conducted a study exploring the potentially complex vocal repertoire of the kea. My study was conducted with wild populatio

Platelet aggregation is mediated primarily by the binding of fibrinogen to its membrane receptor, GPIIb-IIIa, but such an interaction may not be sufficient to support aggregation. This question could potentially be resolved by reconstituting GPIIb-IIIa into a model membrane system.<br>A protocol was developed for the generation of liposomes containing purified GPIIb-IIIa. Flow cytometric techniques confirmed that the receptor was present in the lipid bilayer and were used to evaluate the characteristics of fibrinogen binding to the liposomes, which like fibrinogen-platelet interactions exhibit

Some silvicultural practices in the Knysna Forest are aimed at the sustained-yield production of valuable timber tree species, albeit on limited areas only. This study investigates effects of forest plant species composition and physiognomy on bird and invertebrate communities in three discrete, relatively undisturbed forest types along a dry-wet soil moisture gradient. Using discriminant functions analysis, a 100% floristic and a 78% vegetation structural discrimination was obtained between the three forest types. However, the bird communities of these floristically and structurally different

This thesis investigates the evolution of two secondary sexual characters in birds, large male body size and exaggerated male tail length. To determine whether the elaboration of these two characters is associated with two correlates of sexual selection intensity, mating system and parental care, I collected and examined morphological information for 1,990 species and natural history data for 745 species. Comparative studies should account for the problem of related species sharing similarities through common descent, so here I investigate associations with contrast scores that measure the var

Mestrado em Ecologia Aplicada<br>Ecological changes in the habitats, induced by climate change or the new paradigms of land use, have had enormous effects in the distribution of species, from the fragmentation of the populations to changes on the genome and/or their behavior. In the case of birds, these constraints may cause changes in vocal repertoires among isolated populations. It was recently confirmed that the two last populations of Red-billed Chough (Pyrrhocorax pyrrhocorax) resident in Portugal (populations of the Serra d'Aire e Candeeiros and Sagres) have an apparent gene-flow restric
