Mass stranding of wedge-tailed shearwater chicks in Hawaii.
Unusual numbers of wedge-tailed shearwater (Puffinus pacificus) chicks stranded on Oahu (Hawaii, USA) in 1994. Compared to healthy wedge-tailed shearwater (WTSW) chicks, stranded chicks were underweight, dehydrated, leukopenic, lymphopenic, eosinopenic, and heterophilic; some birds were toxemic and septic. Stranded chicks also were hypoglycemic and had elevated aspartate amino transferase level...
متن کاملINFANTICIDE OF WEDGE-TAILED SHEARWATER PUFFINUS PACIFICUS CHICK AT MARINE CORPS bASE HAWAII
Colonial seabirds are highly susceptible to the effects of conspecific aggression . Their close proximity during the nesting period may result in an increased frequency of aggressive encounters and facilitate their detection (Mock 1984, Clode 1993, Parkes 2005) . In seabirds, conspecific aggression can occur between adults, between adults and chicks or between chicks, and is thought to increase...
متن کاملHigh sea surface temperatures driven by a strengthening current reduce foraging success by penguins
The world's oceans are undergoing rapid, regionally specific warming. Strengthening western boundary currents play a role in this phenomenon, with sea surface temperatures (SST) in their paths rising faster than the global average. To understand how dynamic oceanography influences food availability in these ocean warming "hotspots", we use a novel prey capture signature derived from acceleromet...
متن کاملModeling Nonresident Seabird Foraging Distributions to Inform Ocean Zoning in Central California
Seabird aggregations at sea have been shown to be associated with concentrations of prey. Previous research identified Central California as a highly used foraging area for seabirds, with locally breeding seabirds foraging close to their colonies on Southeast Farallon Island. Herein, we focus on nonresident (i.e. non-locally breeding) seabird species off of Central California. We hypothesized t...
متن کاملanalysis of sea surface current in sea surface temperature images
oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. for instance sea surface temperature (sst) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. the purpose of this thesis is to derive a relatively complete frame...
