Data from: A passerine bird's evolution corroborates the geologic history of the island of New Guinea

Kristy Deiner, Alan R Lemmon, Andrew L. Mack, Robert C. Fleischer, John P. Dumbacher & Alan R. Lemmon
New Guinea is a biologically diverse island, with a unique geologic history and topography that has likely played a role in the evolution of species. Few island-wide studies, however, have examined the phylogeographic history of lowland species. The objective of this study was to examine patterns of phylogeographic variation of a common and widespread New Guinean bird species (Colluricincla megarhyncha). Specifically, we test the mechanisms hypothesized to cause geographic and genetic variation (e.g., vicariance, isolation...

Data from: Stalking the fourth domain in metagenomic data: searching for, discovering, and interpreting novel, deep branches in phylogenetic trees of phylogenetic marker genes

Dongying Wu, Martin Wu, Aaron Halpern, Douglas B. Rusch, Shibu Yooseph, Marvin Frazier, J. Craig Venter & Jonathan A. Eisen
BACKGROUND: Most of our knowledge about the ancient evolutionary history of organisms has been derived from data associated with specific known organisms (i.e., organisms that we can study directly such as plants, metazoans, and culturable microbes). Recently, however, a new source of data for such studies has arrived: DNA sequence data generated directly from environmental samples. Such metagenomic data has enormous potential in a variety of areas including, as we argue here, in studies of...

Data from: Does a facultative mutualism limit species range expansion?

John Stanton-Geddes & Carolyn G. Anderson
The availability and quality of mutualists beyond a species’ range edge may limit range expansion. With the legume Chamaecrista fasciculata, we asked to what extent the availability and quality of rhizobia beyond the range edge limits host range expansion. We tested the effect of rhizobia availability on plant growth by transplanting seed from three locations into five sites spanning C. fasciculata’s range (interior, at the northern and western range edges, and beyond the range edges),...

Data from: A connection between colony biomass and death in Caribbean reef-building corals

Daniel J. Thornhill, Randi D. Rotjan, Brian D. Todd, Geoff C. Chilcoat, Roberto Iglesias-Prieto, Todd C. LaJeunesse, Dustin W. Kemp, Jennifer McCabe Reynolds, Gregory W. Schmidt, Thomas Shannon, Mark E. Warner & William K. Fitt
Increased sea-surface temperatures linked to warming climate threaten coral reef ecosystems globally. To better understand how corals and their endosymbiotic dinoflagellates (Symbiodinium spp.) respond to environmental change, tissue biomass and Symbiodinium density of seven coral species were measured on various reefs approximately every four months for up to thirteen years in the Upper Florida Keys, United States (1994–2007), eleven years in the Exuma Cays, Bahamas (1995–2006), and four years in Puerto Morelos, Mexico (2003–2007). For...

Data from: Behavioral types of predator and prey jointly determine prey survival: potential implications for the maintenance of within species behavioral variation

Jonathan N. Pruitt, John J. Stachowicz & Andrew Sih
Recent studies in animal behavior have emphasized the ecological importance of individual variation in behavioral types (e.g. boldness, activity). Such studies have emphasized how variation in one species affects its interaction with other species. But few (if any) studies simultaneously examine variation in multiple interacting species, despite the potential for coevolutionary responses to work to either maintain or eliminate variation in interacting populations. Here, we investigate how individual differences in behavioral types of both predators...

Data from: Genomics of Compositae weeds: EST libraries, microarrays, and evidence of introgression

Zhao Lai, Nolan C. Kane, Alex Kozik, Kathryn A. Hodgins, Katrina M. Dlugosch, Michael S. Barker, Marta Matvienko, Qian Yu, Kathryn G. Turner, Stephanie A. Pearl, Graeme D.M. Bell, Yi Zou, Chris Grassa, Alessia Guggisberg, Keith L. Adams, James V. Anderson, David P. Horvath, Richard V. Kesseli, John M. Burke, Richard W. Michelmore, Loren H. Rieseberg, Stephanie Anne Pearl & Graeme D. M. Bell
PREMISE OF THE STUDY: Weeds cause considerable environmental and economic damage. However, genomic characterization of weeds has lagged behind that of model plants and crop species. Here we report on the development of genomic tools and resources for 11 weeds from the Compositae family that will serve as a basis for subsequent population and comparative genomic analyses. Because hybridization has been suggested as a stimulus for the evolution of invasiveness, we also analyze these genomic...
