Data from: Avoiding tipping points in fisheries management through Gaussian process dynamic programming

Carl Boettiger, Marc Mangel, Stephan Munch, C. Boettiger & S. Munch
Model uncertainty and limited data are fundamental challenges to robust management of human intervention in a natural system. These challenges are acutely highlighted by concerns that many ecological systems may contain tipping points, such as Allee population sizes. Before a collapse, we do not know where the tipping points lie, if they exist at all. Hence, we know neither a complete model of the system dynamics nor do we have access to data in some...

Data from: Deepwater Horizon oil spill impacts on sea turtles could span the Atlantic

Nathan F. Putman, F. Alberto Abreu-Grobois, Iñaky Iturbe-Darkistade, Emily M. Putman, Paul M. Richards & Philippe Verley
We investigated the extent that the 2010 Deepwater Horizon oil spill potentially affected oceanic-stage sea turtles from populations across the Atlantic. Within an ocean-circulation model, particles were backtracked from the Gulf of Mexico spill site to determine the probability of young turtles arriving in this area from major nesting beaches. The abundance of turtles in the vicinity of the oil spill was derived by forward-tracking particles from focal beaches and integrating population size, oceanic-stage duration...

Data from: Feather corticosterone reveals stress associated with dietary changes in a breeding seabird

Alexis P. Will, Yutaka Watanuki, Dale M. Kikuchi, Nobuhiko Sato, Motohiro Ito, Matt Callahan, Katherine Wynne-Edwards, Scott Hatch, Kyle H. Elliott, Leslie Slater, Akinori Takahashi, Alexander S. Kitaysky, Kyle Elliott, Alexis Will & Alexander Kitaysky
Changes in climate and anthropogenic pressures might affect the composition and abundance of forage fish in the world's oceans. The junk-food hypothesis posits that dietary shifts that affect the quality (e.g., energy content) of food available to marine predators may impact their physiological state and consequently affect their fitness. Previously, we experimentally validated that deposition of the adrenocortical hormone, corticosterone, in feathers is a sensitive measure of nutritional stress in seabirds. Here, we use this...

Data from: Discovery and characterization of single nucleotide polymorphisms in coho salmon, Oncorhynchus kisutch

Hilary A. Starks, Anthony J. Clemento & John Carlos Garza
Molecular population genetic analyses have become an integral part of ecological investigation and population monitoring for conservation and management. Microsatellites have been the molecular marker of choice for such applications over the last several decades, but single nucleotide polymorphism (SNP) markers are rapidly expanding beyond model organisms. Coho salmon (Oncorhynchus kisutch) is native to the north Pacific Ocean and its tributaries, where it is the focus of intensive fishery and conservation activities. As it is...
