Population growth typically involves range expansion and establishment of new breeding sites, while the opposite occurs during declines. Although density-dependence is widely invoked in theoretical studies of emigration and colonization in expanding populations, few empirical studies have documented the mechanisms. Still fewer have documented the direction and mechanisms of individual transfer in declining populations. Here we screen large numbers of pups sampled on their natal rookeries for variation in mtDNA (n=1,106) and 16 microsatellite loci...

Data from: Does functional trait diversity predict aboveground biomass and productivity of tropical forests? Testing three alternative hypotheses

1. Tropical forests are globally important, but it is not clear whether biodiversity enhances carbon storage and sequestration in them. We tested this relationship focusing on components of functional trait biodiversity as predictors. 2. Data are presented for three rain forests in Bolivia, Brazil and Costa Rica. Initial above-ground biomass and biomass increments of survivors, recruits and survivors + recruits (total) were estimated for trees ≥10 cm d.b.h. in 62 and 21 1.0-ha plots, respectively....

Data from: Mito-nuclear discord in six congeneric lineages of Holarctic ducks (genus Anas)

Jeffrey L. Peters, Kevin Winker, Kendra C. Millam, Philip Lavretsky, Irina Kulikova, Robert E. Wilson, Yuri N. Zhuravlev & Kevin G. McCracken
Many species have Holarctic distributions that extend across Europe, Asia, and North America. Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow, unstructured genealogies to deeply divergent lineages. In this study, we sequenced 20 nuclear introns to test for concordant patterns of OW-NW differentiation between mtDNA and nuclear (nu) DNA for six lineages...
