TL;DR: It is suggested that heavily weathered crude oil from the spill imparts significant biological impacts in sensitive Louisiana marshes, some of which remain for over 2 mo following initial exposures.

TL;DR: Killifish collected from Grande Terre had divergent gene expression in the liver and gill tissue coincident with the arrival of contaminating oil and up-regulation of cytochrome P4501A (CYP1A) protein in gill, liver, intestine, and head kidney for over one year following peak landfall of oil compared to fish collected from reference sites.

TL;DR: A histological evaluation and staging criteria for osteoderm development is described for the first time in the American alligator, presenting a potential model for future study of soft tissue mineralization pathologies and providing insight into the morphological and molecular development of osteoderms in other vertebrate lineages.

TL;DR: This investigation emphasizes the importance of including multiple reference populations to clearly link fitness costs or cross-resistance to pollution adaptation, rather than to unrelated environmental or ecological differences.

TL;DR: The cardiovascular system must respond to environmental variation, so the effects of temperature, oxygenation, and toxicants on the functioning of the cardiovascular system are explored.
