Migratory birds depend on resources located in distantly separated ecosystems, potentially
making them vulnerable to rapid environmental changes across theirrange. Yet, we …

In sexual organisms, speciation occurs as genetically based barriers evolve between
populations to cause them to become reproductively isolated. The types and chronology in …

Cryptic divergence (ie evolution of reproductive isolation between populations that are
morphologically similar) is an emerging target of population genetic research in the effort to …

The rainbow trout, Oncorhynchus mykiss, is a partially migratory organism used to study the
genetic control of migration. Much of this research has taken place at a unique site in Sashin …

Species distribution describes the spatial arrangement and spread of individuals within a
species across its geographic range. Multiple factors, such as disturbance, dispersal …

Given the notion that species are population-level lineages and the availability of genomic
data to identify separately evolving populations, researchers usually establish species limits …

A espécie tesourinha Tyrannus savana possui estratégias migratórias que difere entre suas
populações. As populações argentinas realizam migração austral (ultrapassam o trópico de …

The genus Catharus is a monophyletic group of forest-dwelling passerine birds known
colloquially as nightingale-thrushes, or simply thrushes. This dissertation integrates multiple …

Mimicry can directly affect the evolutionary history of models, mimics, and signal receivers.
Mimics often use multimodal signaling to deceive receivers. Jamie et al. showed that brood …

Understanding how diet and life history strategies interact is important for exploring
constraints of available nutrition on energetically expensive life history events in wild …
