1. Heating and cooling rates of the desert tortoise, Gopherus agassizii, were measured in the field and in the laboratory. 2. Heating rates in the field were up to ten times faster than cooling rates. 3. Under controlled conditions, heating rates equalled rates of cooling. 4. Heart rates during heating were significantly faster than during cooling at any particular body temperature. 5. Subcutaneous neck temperatures did not differ from cloacal temperatures during heating or cooling, suggesting a state of continuous vasodilation. 6. Results are interpreted as suggesting that behavioral postures and activities play a greater role than physiology in the determination of thermal exchange rates of the desert tortoise....

In general, ChesMMAP is fishery-independent monitoring survey that uses a large-mesh bottom trawl to sample late juvenile-to-adult fishes in the mainstem of Chesapeake Bay. This program currently provides data on relative abundance, length, weight, sex ratio, maturity, age, and trophic interactions for several important fish species that inhabit the bay seasonally.

NEAMAP stands for NorthEast Area Monitoring and Assessment Program. NEAMAP was developed to meet the needs of fisheries management and stock assessment activities in the northeastern United States. NEAMAP began in 2006 with a fall pilot survey and in 2008 began conducting both a spring and fall survey. NEAMAP samples from Cape Cod, MA south to Cape Hatteras, NC and targets both juvenile and adult fishes. NEAMAP is an integrated, cooperative state/federal data collection program. Its mission is to facilitate the collection and dissemination of fishery-independent information obtained in the Northeast for use by state and federal fisheries management agencies, the fishing industry (commercial and recreational),...
