The durability of plastics in the marine environment has led to concerns regarding the pervasiveness of this debris in remote polar habitats. Microplastic (MP) enrichment in East Antarctic sea ice was measured in one ice core sampled from coastal lan

In recent years, there have been increasing reports of ingestion of marine plastic debris in seabirds. Our aim was to assess the frequency and effects of ingested plastic debris in pre-fledging Short-tailed Shearwaters (Puffinus tenuirostris) in Tasm

Access to human-derived food is thought the major cause of population increases in many gull species, and the degree to which urbanized gulls depend upon anthropogenic food may be resolved by isotopic benchmarks. Stable isotope ratios (δ13C and δ15

Urban populations of several gull species worldwide are increasing dramatically and this is often assumed to be a result of greater access to anthropogenic food obtained in urbanized environments. This research investigated the potential effects of a

Concentrations of total polychlorinated biphenyls (PCBs) and organochlorine insecticides, including the 1 1,1-trichloro-2, 2′-bis-p-chlorophenyl-ethane (DDT) complex, were measured in the plasma of chicks and adults and in eggs of Laysan albatrosse

Anthropogenic organic contaminants have been found in even the most remote locations. To assess the global distribution and possible effects of such contaminants, we examined the tissues of two species of albatross collected from Midway Atoll in the

Deformities have been reported in many species of colonial waterbirds from several localities on the Laurentian Great Lakes. The hypothesis that deformities were caused by either polychlorinated biphenyls (PCBs) or contaminants measured as 2,3,7,8-te

Chlorinated hydrocarbons such as polychlorinated biphenyls (PCBs) and chlorinated insecticides have often been detected in Great Lakes fish-eating birds at concentrations that are correlated with greater than expected embryo mortality and reduced rep

Water quality criteria (WQC) can be derived in several ways. The usual techniques involve hazard and risk assessment procedures. For non-persistent, non-biomagnified compounds and elements, WQC are experimentally derived from their acute and chronic

In the 2 years that followed the 100-year flood incident of September 1986 in the Saginaw River/Bay ecosystem, the reproduction of Caspian terns collapsed and then slowly recovered. Egg viability and fledging rates of hatched chicks were drastically
