Data from: Strong selection against hybrids maintains a narrow contact zone between morphologically cryptic lineages in a rainforest lizard

Sonal Singhal & Craig Moritz
Phenotypically cryptic lineages comprise an important yet understudied part of biodiversity; in particular, we have much to learn about how these lineages are formed and maintained. To better understand the evolutionary significance of such lineages, we studied a hybrid zone between two morphologically-cryptic phylogeographic lineages in the rainforest lizard, Lampropholis coggeri. Analyzing a multilocus genetic dataset through cline inference, individual-based methods and population measures of disequilibrium and using simulations to explore our genetic results in...

Data from: Comparative multi-locus phylogeography confirms multiple vicariance events in co-distributed rainforest frogs

Rayna C Bell, Jason B MacKenzie, Michael J Hickerson, Krystle L Chavarría, Michael Cunningham, Stephen Williams, Craig Moritz, K. L. Chavarria, J. B. MacKenzie, S. Williams, R. C. Bell, M. Cunningham, C. Moritz & M. J. Hickerson
Though Pleistocene refugia are frequently cited as drivers of species diversification, comparisons of molecular divergence among sister species typically indicate a continuum of divergence times from the late Miocene, rather than a clear pulse of speciation events at the Last Glacial Maximum (LGM). Community-scale inference methods that explicitly test for multiple vicariance events, and account for differences in ancestral effective population size and gene flow, are well suited for detecting heterogeneity of species’ responses to...

Data from: Different gene families in Arabidopsis thaliana transposed in different epochs and at different frequencies throughout the rosids

Margaret R. Woodhouse, Haibao Tang & Michael Freeling
Certain types of gene families, such as those encoding most families of transcription factors, maintain their chromosomal syntenic positions throughout Angiosperm evolutionary time. Other, non-syntenic gene families are prone to deletion, tandem duplication, and transposition. Here we describe the chromosomal positional history of all genes in Arabidopsis thaliana (A. thaliana) throughout the rosid superorder. We introduce a public database where researchers can look up the positional history of their favorite A. thaliana gene or gene...

Data from: Host and habitat specialization of avian malaria in Africa

Studies of both vertebrates and invertebrates have suggested that specialists, as compared to generalists, are likely to suffer more serious declines in response to environmental change. Less is known about the effects of environmental conditions on specialist vs. generalist parasites. Here, we study the evolutionary strategies of malaria parasites (Plasmodium spp.) among different bird host communities. We determined the parasite diversity and prevalence of avian malaria in three bird communities in the lowland forests in...

Data from: Role of recent and old riverine barriers in fine scale population genetic structure of Geoffroy's Tamarin (Saguinus geoffroyi) in the Panama Canal Watershed

Samuel L. Díaz-Muñoz
The role of physical barriers in promoting population divergence and genetic structuring is well known. While it is well established that animals can show genetic structuring at small spatial scales, less well resolved is how the timing of the appearance of barriers affects population structure. This study uses the Panama Canal watershed as a test of the effects of old and novel riverine barriers in creating population structure in Saguinus geoffroyi, a small cooperatively breeding...

Data from: Rates of morphological evolution are correlated with species richness in salamanders

Daniel L. Rabosky & Dean C. Adams
The tempo and mode of species diversification and phenotypic evolution vary widely across the tree of life, yet the relationship between these processes is poorly known. Previous tests of the relationship between rates of phenotypic evolution and rates of species diversification have assumed that species richness increases continuously through time. If this assumption is violated, simple phylogenetic estimates of net diversification rate may bear no relationship to processes that influence the distribution of species richness...

Data from: Land management practices associated with house loss in wildfires

Philip Gibbons, Linda Van Bommel, A. Malcolm Gill, Geoffrey J. Cary, Don A. Driscoll, Ross A. Bradstock, Emma A. Knight, Max A. Moritz, Scott L. Stephens, David B. Lindenmayer & Emma Knight
Losses to life and property from unplanned fires (wildfires) are forecast to increase because of population growth in peri-urban areas and climate change. In response, there have been moves to increase fuel reduction—clearing, prescribed burning, biomass removal and grazing—to afford greater protection to peri-urban communities in fire-prone regions. But how effective are these measures? Severe wildfires in southern Australia in 2009 presented a rare opportunity to address this question empirically. We predicted that modifying several...
