Molecular dating for phylogenies containing a mix of populations and species by using Bayesian and RelTime approaches

Beatriz Mello, Qiqing Tao, Jose Barba-Montoya & Sudhir Kumar
Simultaneous molecular dating of population and species divergences is essential in many biological investigations, including phylogeography, phylodynamics, and species delimitation studies. In these investigations, multiple sequence alignments consist of both intra- and inter-species samples (mixed samples). As a result, the phylogenetic trees contain inter-species, inter-population, and within-population divergences. Bayesian relaxed clock methods are often employed in these analyses, but they assume the same tree prior for both inter- and intra-species branching processes and require specification...

Data from: Experimental study of species invasion – early population dynamics and role of disturbance in invasion success

David Reznick, Sebastiano De Bona, Andres Lopez-Sepulcre, Mauricio Torres, Ronald Bassar, Paul Bentzen & Joseph Travis
Much of our understanding of natural invasions is retrospective, based on data acquired after invaders become established. As a consequence, we know little about the characteristics of the early population growth and habitat use of the invaders during establishment. Here we report on experimental introductions of guppies into natural streams in which we conducted monthly censuses of each population. Two of the four introductions were in streams with thinned canopies, which mimics a common form...

Habitat suitability modeling to predict the spatial distribution of cold-water coral communities affected by the Deepwater Horizon oil spill

Samuel Georgian, Kody Kramer, Miles Saunders, William Shedd, Harry Roberts, Christopher Lewis, Chuck Fisher & Erik Cordes
Aim: The Deepwater Horizon disaster resulted in the largest accidental marine oil spill in history and caused extensive injury to deep-sea habitats, including cold-water coral communities dominated by Paramuricea species. One of the primary difficulties in assessing the full extent of the injury to cold-water coral ecosystems is the extreme paucity of observational data and the subsequent lack of knowledge of their distribution within the affected region. The aim of this study was to use...

Bedforms of Thwaites Glacier, West Antarctica: Character and Origin

R.B. Alley, N. Holschuh, D.R. MacAyea, B.R. Parizek, L. Zoet, K. Riverman, A. Muto, K. Christianson, E. Clyne, S. Anandakrishnan & N.T. Stevens
Bedforms of Thwaites Glacier, West Antarctica both record and affect ice flow. Thwaites Glacier flows across the tectonic fabric of the West Antarctic rift system with its bedrock highs and sedimentary basins. Swath radar and seismic surveys of the glacier bed have revealed soft-sediment flutes 100 m or more high extending 15 km or more across basins downglacier from bedrock highs, and ending at prominent hard-bedded moats on stoss sides of the next topographic highs....

Swimming and defense - competing needs across ontogeny in armored fishes (Agonidae)

Matthew Kolmann, Cassandra Donatelli, Tessa Peixoto, Janne Pfeiffenberger & Adam Summers
Biological armors are potent model systems for understanding the complex series of competing demands on protective exoskeletons; after all, armored organisms are the product of millions of years of refined engineering under the harshest conditions. Fishes are no strangers to armor, with various types of armor plating common to the 400 million years of evolution in both jawed and jawless fishes. Here we focus on the poachers (Agonidae), a family of armored fishes native to...

Resolution of the house mouse (Mus musculus) phylogeny by integration over isolation-with-migration histories

Bettina Harr, Megan Phifer-Rixey & Jody Hey
The three main subspecies of house mice, Mus musculus castaneus, Mus musculus domesticus , and Mus musculus musculus, are estimated to have diverged ~325-500KYA. Resolution of the details of their evolutionary history is complicated by their relatively recent divergence, ongoing gene flow among the subspecies, and complex demographic histories. Previous studies have been limited to some extent by the number of loci surveyed and/or by the scope of the method used. Here we apply a...
