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...
