Mercury in feathers from Chilean birds: influence of location, feeding strategy, and taxonomic affiliation.
This study reports baseline concentrations of mercury (Hg) in feathers from different species of birds sampled at various locations off the Chilean coast (Southeastern Pacific). Hg concentrationsExpand
A PROTRACTED FORAGING AND ATTENDANCE CYCLE IN FEMALE JUAN FERNÁNDEZ FUR SEALS
TLDR
It is suggested that distribution of prey, irrespective of latitude, dictates foraging patterns of fur seals and leads to the exceptionally long foraging trips and visits ashore observed in this species. Expand
Acute and chronic toxicity of atrazine and its metabolites deethylatrazine and deisopropylatrazine on aquatic organisms
TLDR
The results suggest that short-term exposures of these chemicals to algae and amphipods to concentrations routinely detected in surface waters are unlikely to be a cause of concern, but the unexpected high sensitivity of Diporeia spp. Expand
The Toxicogenome of Hyalella azteca: A Model for Sediment Ecotoxicology and Evolutionary Toxicology.
TLDR
The H. azteca genome will greatly facilitate development of genomic tools for environmental assessments and promote an understanding of how evolution shapes toxicological pathways with implications for environmental and human health. Expand
Drinking-Water Herbicide Exposure in Indiana and Prevalence of Small-for-Gestational-Age and Preterm Delivery
TLDR
It is found that atrazine, and perhaps other co-occurring herbicides in drinking water, is associated with an increased prevalence of SGA, but not preterm delivery. Expand
Use of GC × GC/TOF‐MS and LC/TOF‐MS for metabolomic analysis of Hyalella azteca chronically exposed to atrazine and its primary metabolite, desethylatrazine
TLDR
Overall, this research demonstrates the feasibility of utilizing metabolomic profiling of invertebrate species exposed to environmental contaminants as a way to determine mechanisms of toxicity. Expand
Comparative Biochemistry and Physiology, Part A
The metabolic rate of harp (Pagophilus groenlandicus), harbor (Phoca vitulina), and ringed seals (Pusa hispida) was measured at various temperatures in air and water to estimate basal metabolic ratesExpand
Toxicity of soybean rust fungicides to freshwater algae and Daphnia magna
TLDR
This work determined the toxicity of six fungicides to the unicellular algae Pseudokirchneriella subcapitata and the aquatic invertebrate, Daphnia magna and found that levels of concern of some fungicides were lower than annual average runoff concentrations predicted for Indiana. Expand
Bioaccumulation and biomagnification of polybrominated diphenyl ethers in a food web of Lake Michigan
TLDR
Diporeia could be one of the main dietary sources of BDE-209 for fish in Lake Michigan; BDE and 100 biomagnified within this food chain; the concentration of Bde-209 decreased at higher trophic levels, suggesting partial uptake and/or biotransformation of BME in the Lake Michigan food web. Expand
Risk of limb birth defects and mother's home proximity to cornfields.
BACKGROUND Although previous studies have linked proximity to crops and birth defects, they lacked individual-level exposure data and none was based on using planted area instead of linear proximityExpand
