The cyprinid tribe Labeonini (sensu Rainboth, 1991) is a large group of freshwater fishes containing around 40 genera and 400 species. They are characterized by an amazing diversity of modifications to their lips and associated structures. In this study, a total of 34 genera and 142 species of putative members of this tribe, which represent most of the generic diversity and more than one third of the species diversity of the group, were sampled and...

Data from: Chromosome number evolves independently of genome size in a clade with non-localized centromeres (Carex: Cyperaceae)

Kyong-Sook Chung, Andrew L. Hipp & Eric H. Roalson
The effects of chromosome rearrangement on genome size are poorly understood. While chromosome duplications and deletions have predictable effects on genome size, chromosome fusion, fission, and translocation do not. In this study, we investigate genome size and chromosome number evolution in 87 species of Carex, one of the most species-rich genera of flowering plants and one that has undergone an exceptionally high rate of chromosome rearrangement. Using phylogenetic generalized least squares regression, we find that...

Data from: Using supermatrices for phylogenetic inquiry: an example using the sedges

Cody E. Hinchliff & Eric H. Roalson
In this article, we use supermatrix data-mining methods to reconstruct a large, highly inclusive phylogeny of Cyperaceae from nucleotide data available on GenBank. We explore the properties of these trees and their utility for phylogenetic inference, and show that even the highly incomplete alignments characteristic of supermatrix approaches may yield very good estimates of phylogeny. We present a novel pipeline for filtering sparse alignments to improve their phylogenetic utility by maximizing the partial decisiveness of...

Data from: Demographic and population-genetic tests provide mixed support for the abundant center hypothesis in the endemic plant Leavenworthia stylosa

Andrea L. Dixon, Christopher R. Herlihy & Jeremiah W. Busch
The abundant centre hypothesis (ACH) assumes that population abundance, population size, density and per-capita reproductive output should peak at the centre of a species' geographic range and decline towards the periphery. Increased isolation among and decreased reproductive output within edge populations should reduce within-population genetic diversity and increase genetic differentiation among edge relative to central populations. The ACH also predicts asymmetrical gene flow, with net movement of migrants from the centre to edges. We evaluated...

Data from: Rangewide landscape genetics of an endemic Pacific northwestern salamander

Daryl R. Trumbo, Stephen F. Spear, Jason Baumsteiger & Andrew Storfer
A species' genetic structure often varies in response to ecological and landscape processes that differ throughout the species' geographic range, yet landscape genetics studies are rarely spatially replicated. The Cope's giant salamander (Dicamptodon copei) is a neotenic, dispersal-limited amphibian with a restricted geographic range in the Pacific northwestern USA. We investigated which landscape factors affect D. copei gene flow in three regions spanning the species' range, which vary in climate, landcover and degree of anthropogenic...
