Data from: The role of inbreeding depression and mating system in the evolution of heterostyly

We investigated the role of morph-based differences in the expression of inbreeding depression in loss of the mid-styled morph from populations of tristylous Oxalis alpina as proposed by theoretical analyses. The extent of self-compatibility of reproductive morphs, the degree of self-fertilization, and the magnitude of inbreeding depression were investigated in three populations of O. alpina differing in their tristylous incompatibility relationships. All three populations exhibited significant inbreeding depression. In two populations with highly modified tristylous...

Data from: Species tree reconstruction of a poorly resolved clade of salamanders (Ambystomatidae) using multiple nuclear loci

Joshua S. Williams, John H. Niedzwiecki & David W. Weisrock
The analysis of diverse data sets can yield different phylogenetic estimates that challenge systematists to explain the source of discordance. The mole salamanders (family Ambystomatidae) are a classic example of this phylogenetic conflict. Previous attempts to resolve the ambystomatid species tree using allozymic, morphological, and mitochondrial sequence data have yielded different estimates, making it unclear which data source best approximates ambystomatid phylogeny and which ones yield phylogenetically inaccurate reconstructions. To shed light on this conflict,...

Data from: Reconstructing the microbial diversity and function of pre-agricultural tallgrass prairie soils in the United States

Noah Fierer, Joshua Ladau, Jose C. Clemente, Jonathan W. Leff, Sarah M. Owens, Katherine S. Pollard, Rob Knight, Jack A. Gilbert & Rebecca L. McCulley
Native tallgrass prairie once dominated much of the midwestern United States, but this biome and the soil microbial diversity that once sustained this highly productive system have been almost completely eradicated by decades of agricultural practices. We reconstructed the soil microbial diversity that once existed in this biome by analyzing relict prairie soils and found that the biogeographical patterns were largely driven by changes in the relative abundance of Verrucomicrobia, a poorly studied bacterial phylum...

Data from: Multiple aspects of plasticity in clutch size vary among populations of a globally distributed songbird

David F. Westneat, Veronika Bókony, Terry Burke, Olivier Chastel, Henrik Jensen, Thomas Kvalnes, Ádám Z. Lendvai, András Liker, Douglas Mock, Julia Schroeder, P. L. Schwagmeyer, Gabriele Sorci & Ian R. K. Stewart
1. Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms in native locations. Variation in reaction norm attributes is a critical element to understanding plasticity in life history, yet we know relatively little about the ways in which reaction norms vary within and among populations. 2. We amassed data on clutch size from marked females in...
