Journal ArticleDOI
Global Seabird Response to Forage Fish Depletion-One-Third for the Birds
Philippe Cury,Ian L. Boyd,Sylvain Bonhommeau,Tycho Anker-Nilssen,Robert J. M. Crawford,Robert W. Furness,James A. Mills,Eugene J. Murphy,Henrik Österblom,Michelle Paleczny,John F. Piatt,Jean-Paul Roux,Lynne J. Shannon,William J. Sydeman +13 more
TL;DR: A threshold in prey abundance is identified below which seabirds experience consistently reduced and more variable productivity and provides an indicator of the minimal forage fish biomass needed to sustain seabird productivity over the long term.
Journal ArticleDOI
Measuring metabolic rate in the field: the pros and cons of the doubly labelled water and heart rate methods
TL;DR: The pros and cons of the two most commonly used methods for measuring FMR are discussed, gaining in popularity owing to its high accuracy and versatility, though the logistic constraint of performing calibrations can make its use a relatively extended process.
Journal ArticleDOI
The Consequence of Tree Pests and Diseases for Ecosystem Services
TL;DR: The spread of tree diseases, as a result of globalization and climate change, is reviewed, and the resulting damage to timber and fruit production, to climate regulation, and to parks and woodlands caused by tree diseases is analyzed.
Journal ArticleDOI
The global contribution of forage fish to marine fisheries and ecosystems
Ellen K. Pikitch,Konstantine J. Rountos,Timothy E. Essington,Christine Santora,Daniel Pauly,Reg Watson,Ussif Rashid Sumaila,P. Dee Boersma,Ian L. Boyd,David O. Conover,Philippe Cury,Selina S. Heppell,Edward D. Houde,Marc Mangel,Keith Sainsbury,Robert S. Steneck,Tess M Geers,Natasha J. Gownaris,Stephan B. Munch +18 more
TL;DR: Forage fish play a pivotal role in marine ecosystems and economies worldwide by sustaining many predators and fisheries directly and indirectly as discussed by the authors, and they contribute a total of about $16.9 billion USD to global fisheries values annually.
Journal ArticleDOI

TL;DR: It is shown that in both exposure conditions beaked whales stopped echolocating during deep foraging dives and moved away, indicating similar disruption of foraging behavior and avoidance by beaked whale in the two different contexts, at exposures well below those used by regulators to define disturbance.
