Neotropical migratory birds are declining across the Western Hemisphere, but conservation efforts have been hampered by the inability to assess where migrants are most limited – the breeding grounds, migratory stopover sites, or wintering areas. A major challenge has been the lack of an efficient, reliable, and broadly applicable method for measuring the strength of migratory connections between populations across the annual cycle. Here we show how high-resolution genetic markers can be used to identify...
Data from: DNA barcoding provides support for a cryptic species complex within the globally distributed and fishery important opah (Lampris guttatus)John R. Hyde, Karen E. Underkoffler & Meagan A. Sundberg
The cornerstone of fisheries management relies on a solid taxonomic base and an understanding of how animals can be grouped into coherent management units. Surprisingly little is known about the basic biology and ecology of opah (Lampris guttatus), a globally distributed species that is commercially exploited and regionally common in the North Pacific. Recent efforts to collect life history data on this species uncovered evidence of two North Pacific morphotypes. Sequencing of the mitochondrial cytochrome...
Data from: Density drives polyandry and relatedness influences paternal success in the Pacific gooseneck barnacle, Pollicipes elegansLouis V. Plough, Amy Moran & Peter Marko
Background: Polyandry is a common mating strategy in animals, increasing female fitness through direct (material) and indirect (genetic) benefits. Most theories about the benefits of polyandry come from studies of terrestrial animals, which have relatively complex mating systems and behaviors; less is known about the potential benefits of polyandry in sessile marine animals, for which potential mates may be scarce and females have less control over pre-copulatory mate choice. Here, we used microsatellite markers to...
Data from: Marine communities on oil platforms in Gabon, West Africa: high biodiversity oases in a low biodiversity environmentAlan M. Friedlander, Enrique Ballesteros, John Michael Fay, Enric Sala & Michael Fay
The marine biodiversity of Gabon, West Africa has not been well studied and is largely unknown. Our examination of marine communities associated with oil platforms in Gabon is the first scientific investigation of these structures and highlights the unique ecosystems associated with them. A number of species previously unknown to Gabonese waters were recorded during our surveys on these platforms. Clear distinctions in benthic communities were observed between older, larger platforms in the north and...
This study developed species distribution models (SDMs) of the 6 dominant Hawaiian coral species (Montipora capitata, Montipora flabellata, Montipora patula, Pocillopora meandrina, Porites compressa, and Porites lobata) around the main Hawaiian Islands (MHI). To construct the SDMs, we used boosted regression tree (BRT) models to investigate relationships between the abundance (i.e. benthic cover) of each species with a set of environmental variables for the time period from 2000 to 2009. Mean significant wave height and...
