Ecological traits drive genetic structuring in two open-habitat birds from the morphologically cryptic genus Elaenia (Aves: Tyrannidae)
<p>Understanding the relative contributions of the many factors that shape population genetic structuring is a central theme in evolutionary and conservation biology. Historically, abiotic or extrinsic factors (such as geographic barriers or climatic shifts) have received greater attention than biotic or intrinsic factors (such as dispersal or migration). This focus stems in part from the logistical difficulties in taking a comparative phylogeographic approach that contrasts species that have experienced similar abiotic conditions during their evolution yet differ in the intrinsic attributes that might shape their genetic structure. To explore the effects of intratropical migration on the genetic structuring of Neotropical birds, we chose two congeneric species, the Lesser Elaenia (<em>Elaenia chiriquensis</em>) and the Plain-crested Elaenia (<em>E. cristata</em>), that are largely sympatric, and which have similar plumage, habitat preferences, and breeding phenology. Despite these many commonalities, they differ in migratory behavior: <em>E. chiriquensis</em> is an intratropical migratory species while <em>E. cristata</em> is sedentary. We used a reduced representation genomic approach to test whether migratory behavior is associated with increased gene flow and therefore lower genetic population structure. As predicted, we found notably stronger genetic structuring in the sedentary species than in the migratory ones. <em>E. cristata</em> comprises genetic clusters with geographic correspondence throughout its distribution, while there are no geographic groups within Brazil for <em>E. chiriquensis</em>. This comparison adds to the growing evidence about how intrinsic traits like migration can shape the genetic structuring of birds, and advances our understanding of the diversification patterns of the understudied, open habitat species from South America.</p>

Figure 3. Results of the generalised linear model between: (a) precipitation seasonality and clutch size; (b) temperature seasonality and clutch size; and (c) latitude and clutch size for six species of Todirostrum. (d) Correlation between latitude and length of the breeding season for three species of Todirostrum. Clutch sizes were averaged for each species and locality. Data on the length of breeding season are from: Hellebrekers (1942), Skutch (1951), Haverschmidt (1968), Thomas (1979), Marceliano (1982), Ramo and Busto (1984), Cruz and Andrews (1989), Stiles and Skutch (1989), Verea et al. (2009), and this study. Points are semi-transparent due to overplotting.
