From birds to butterflies: animal movement patterns and stable isotopes.
The ecology of stress: effects of the social environment
The relationship between dominance and glucocorticoid levels varies among species, populations and years, in a manner that depends on the stability of the social hierarchy, environmental conditions, the type of breeding system and the manner in which high rank is obtained and maintained.

A unifying model is developed that predicts evolutionary responses to environmentally driven fluctuating selection and is used to explore the potential consequences of altered environmental cycles and the potential value of evolutionary thinking in the study of global climate change.
Linking Breeding and Wintering Ranges of a Migratory Songbird Using Stable Isotopes
It is shown that most birds wintering on western Caribbean islands come from the northern portion of the species' North American breeding range, whereas those on more easterly islands are primarily from southern breeding areas, indicating considerable population mixing with respect to breeding longitude.

It is shown that evolutionary lability of these colors is associated with both morphological and lineage diversification in African starlings, and key innovations in ornament production can provide high phenotypic trait variability, leading to dramatic effects on the tempo and mode of diversification.
Sexual selection accelerates signal evolution during speciation in birds

It is shown that elevated levels of sexual selection are associated with more rapid phenotypic divergence between related lineages, and that this effect is restricted to male plumage traits proposed to function in mate choice and species recognition.
THE ROLE OF SPECIES ABUNDANCE IN DETERMINING BREEDING ORIGINS OF MIGRATORY BIRDS WITH STABLE ISOTOPES
This work reports the first illustration of using likelihood-based assignment with stable isotope data, and argues that a more natural formulation of the assignment problem should be based on the probability of origin given the observed data, or the posterior probability oforigin.
Environmental Uncertainty and the Global Biogeography of Cooperative Breeding in Birds
Spatiotemporal environmental variation, risk aversion, and the evolution of cooperative breeding as a bet-hedging strategy

Using data from a 10-y study of cooperatively breeding superb starlings living in a temporally and spatially variable savanna ecosystem, it is found that variance in reproductive success declined with increasing environmental quality, increasing territory quality, and increasing group size, which is itself related to environmental variation.
