Mercury in feathers from Chilean birds: influence of location, feeding strategy, and taxonomic affiliation.
A PROTRACTED FORAGING AND ATTENDANCE CYCLE IN FEMALE JUAN FERNÁNDEZ FUR SEALS
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.
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 rates…
Acute and chronic toxicity of atrazine and its metabolites deethylatrazine and deisopropylatrazine on aquatic organisms
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.

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.

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.
Toxicity of soybean rust fungicides to freshwater algae and Daphnia magna
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.

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.
