Data from: Home bodies and wanderers: sympatric lineages of the deep-sea black coral Leiopathes glaberrima

Dannise V. Ruiz-Ramos, Miles G. Saunders, Charles R. Fisher, Iliana B. Baums & Miles Saunders
Colonial corals occur in a wide range of marine benthic habitats from the shallows to the deep ocean, often defining the structure of their local community. The black coral Leiopathes glaberrima is a long-lived foundation species occurring on carbonate outcrops in the Northern Gulf of Mexico (GoM). Multiple color morphs of L. glaberrima grow sympatrically in the region. Morphological, mitochondrial and nuclear ribosomal markers supported the hypothesis that color morphs constituted a single biological species...

Neal Stewart, Gane K-S. Wong … & Claude De Pamphilis
Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, however, to date, these studies have relied almost exclusively on plastid data. Methods: Here we take a curated phylogenomics approach to infer the...

Data from: Microbial invasion of the Caribbean by an Indo-Pacific coral zooxanthella

D. Tye Pettay, Drew C. Wham, Robin T. Smith, Roberto Iglesias-Prieto & Todd C. LaJeunesse
Human-induced environmental changes have ushered in the rapid decline of coral reef ecosystems, particularly by disrupting the symbioses between reef-building corals and their photosymbionts. However, escalating stressful conditions enable some symbionts to thrive as opportunists. We present evidence that a stress-tolerant “zooxanthella” from the Indo-Pacific Ocean, Symbiodinium trenchii, has rapidly spread to coral communities across the Greater Caribbean. In marked contrast to populations from the Indo-Pacific, Atlantic populations of S. trenchii contained exceptionally low genetic...

Data from: Energetic constraint of non-monotonic mass change during offspring growth: a general hypothesis and application of a new tool

Jennifer M. Arnold, Ian C. Nisbet & Stephen A. Oswald
1. Postnatal growth is an important life-history trait and can be a sensitive indicator of ecological stress. For over 50 years, monotonic (never-decreasing) growth has been viewed as the predominant trajectory of postnatal mass change in most animal species, notably among birds. However, prevailing analytical approaches and energetic constraints may limit detection of non-monotonic (or multi-phasic), determinate growth patterns, such as mass recession in birds (weight-loss prior to fledging, preceded by overshooting adult mass), which...

Data from: Detecting recent selective sweeps while controlling for mutation rate and background selection

Christian D. Huber, Michael DeGiorgio, Ines Hellmann & Rasmus Nielsen
A composite likelihood ratio test implemented in the program SweepFinder is a commonly used method for scanning a genome for recent selective sweeps. SweepFinder uses information on the spatial pattern (along the chromosome) of the site frequency spectrum (SFS) around the selected locus. To avoid confounding effects of background selection and variation in the mutation process along the genome, the method is typically applied only to sites that are variable within species. However, the power...
