Many species have Holarctic distributions that extend across Europe, Asia, and North America. Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow, unstructured genealogies to deeply divergent lineages. In this study, we sequenced 20 nuclear introns to test for concordant patterns of OW-NW differentiation between mtDNA and nuclear (nu) DNA for six lineages...
Data from: Geographic differences in vertical connectivity in the Caribbean coral Montastraea cavernosa despite high levels of horizontal connectivity at shallow depthsXaymara Serrano, Iliana B. Baums, Katherine O'Reilly, Tyler B. Smith, Ross J. Jones, Tonya L. Shearer, Flavia L. D. Nunes & Andrew C. Baker
The Deep Reef Refugia Hypothesis proposes that deep reefs can act as local recruitment sources for shallow reefs following disturbance. To test this hypothesis, nine polymorphic DNA microsatellite loci were developed and used to assess vertical connectivity in 583 coral colonies of the Caribbean depth-generalist coral Montastraea cavernosa. Samples were collected from three depth zones (≤10 m, 15-20 m and ≥25 m) at sites in Florida Upper Keys, Lower Keys and Dry Tortugas), Bermuda, and...
Data from: In a long-term experimental demography study, excluding ungulates reversed invader’s explosive population growth rate and restored nativesSusan Kalisz, Rachel B. Spigler & Carol C. Horvitz
A major goal in ecology is to understand mechanisms that increase invasion success of exotic species. A recent hypothesis implicates altered species interactions resulting from ungulate herbivore overabundance as a key cause of exotic plant domination. To test this hypothesis, we maintained an experimental demography deer exclusion study for 6 y in a forest where the native ungulate Odocoileus virginianus (white-tailed deer) is overabundant and Alliaria petiolata (garlic mustard) is aggressively invading. Because population growth...
Data from: Return of the ghosts of dispersal past: historical spread and contemporary gene flow in the blue sea star Linckia laevigataEric D. Crandall, Eric A. Treml, Libby Liggins, Lachlan Gleeson, Nina Yasuda, Paul Barber, Gert Wörheide, Cynthia Riginos & Paul H Barber
Marine animals inhabiting the Indian and Pacific oceans have some of the most extensive species ranges in the world, sometimes spanning over half the globe. These Indo-Pacific species present a challenge for study with both geographic scope and sampling density as limiting factors. Here, we augment and aggregate phylogeographic sampling of the iconic blue sea star, Linckia laevigata Linnaeus, 1758, and present one of the most geographically comprehensive genetic studies of any Indo-Pacific species to...
The northern Andes, with their steep elevational and climate gradients, are home to an exceptional diversity of flora and fauna, particularly rich in avian species that have adapted to divergent ecological conditions. With this diversity comes the opportunity for parasites to exploit a wide breadth of avian hosts. However, little research has focused on examining the patterns of prevalence and lineage diversity of avian parasites in the Andes. Here, we screened a total of 428...
Data from: Conserved genetic regions across angiosperms as tools to develop single copy nuclear markers in gymnosperms: an example using cycadsDayana E. Salas-Leiva, Alan W. Meerow, Javier Francisco-Ortega, Michael Calonje, M. Patrick Griffith, Dennis W. Stevenson & Kyoko Nakamura
Several individuals of the Caribbean Zamia clade and other cycad genera were used to identify single copy nuclear genes for phylogeographic and phylogenetic studies in Cycadales. Two strategies were employed to select target loci: 1) a tblastX search of Arabidopsis conserved ortholog sequence (COS) set and, 2) a tblastX search of Arabidopsis-Populus-Vitis-Oryza Shared Single Copy genes (APVO SSC) against the EST Zamia databases in Genbank. From the first strategy, 30 loci were selected, and from...
