Introduced predators transform subarctic islands from grassland to tundraD A Croll
Department of Ecology and Evolutionary Biology, Island Conservation, University of California Santa Cruz, Santa Cruz, CA 95060, USA
Science 307:1959-61. 2005..By preying on seabirds, foxes reduced nutrient transport from ocean to land, affecting soil fertility and transforming grasslands to dwarf shrub/forb-dominated ecosystems...
The diving behavior of blue and fin whales: is dive duration shorter than expected based on oxygen stores?D A Croll
Institute of Marine Sciences, A316 Earth and Marine Sciences Bldg, University of California, Santa Cruz, CA 95064, USA
Comp Biochem Physiol A Mol Integr Physiol 129:797-809. 2001..We propose instead that short duration diving in large whales results from either: (1) dispersal behavior of prey; or (2) a high energetic cost of foraging...
Only male fin whales sing loud songsDonald A Croll
Department of Ecology and Evolutionary Biology, Center for Ocean Health, University of California, Santa Cruz, California 95060, USA
Nature 417:809. 2002..This finding indicates that they may function as male breeding displays, and will help to focus concern on the impact of human-generated low-frequency sounds on recovering whale populations...
Introduced rats indirectly change marine rocky intertidal communities from algae- to invertebrate-dominatedCarolyn M Kurle
Department of Ecology and Evolutionary Biology, University of California, 100 Shaffer Road, Santa Cruz, CA 95060, USA
Proc Natl Acad Sci U S A 105:3800-4. 2008....
Contaminant-associated alteration of immune function in black-footed albatross (Phoebastria nigripes), a North Pacific predatorMyra E Finkelstein
Environmental Toxicology, University of California, Santa Cruz, California 95064, USA
Environ Toxicol Chem 26:1896-903. 2007..Our results raise concern regarding detrimental health effects in pelagic predators exposed to persistent marine pollutants...
Sink or swim: strategies for cost-efficient diving by marine mammalsT M Williams
Department of Biology, EMS A316, University of California, Santa Cruz, CA 95064, USA
Science 288:133-6. 2000..2 to 59.6% reduction in diving energetic costs. This energy-conserving strategy allows marine mammals to increase aerobic dive duration and achieve remarkable depths despite limited oxygen availability when submerged...
Immune function of cryopreserved avian peripheral white blood cells: potential biomarkers of contaminant effects in wild birdsM Finkelstein
Department of Ocean Sciences, 1156 High St, University of California, Santa Cruz, California 95064, USA
Arch Environ Contam Toxicol 44:502-9. 2003..This study will facilitate greater use of ex vivo immune function assays as tools to study effects of contaminant exposure in wildlife by demonstrating the viability and functionality of cryopreserved avian cells...
High feeding costs limit dive time in the largest whalesA Acevedo-Gutiérrez
Institute of Marine Sciences, Center for Ocean Health, 100 Shaffer Road, University of California, Santa Cruz, CA 95060, USA
J Exp Biol 205:1747-53. 2002..As a corollary, because of their limited foraging time under water, these whales may be particularly vulnerable to perturbations in prey abundance...

Institute of Marine Sciences, University of California Santa Cruz, Santa Cruz, California, United States of America
PLoS ONE 6:e27874. 2011....
