Size-dependent, sex-dependent and seasonal changes in insulin-lige growth-factor-I in the loggerhead sea turtle Size-dependent, sex-dependent and seasonal changes in insulin-lige growth-factor-I in the loggerhead sea turtle

This study examines size-dependent, sex-dependent, and seasonal fluctuations in plasma insulin-like growth factor-I (IGF-I) concentrations in loggerhead sea turtles (Caretta caretta). Loggerhead turtles (n = 158) were captured in shrimp trawler nets during a 12-month survey in Cape Canaveral Channel, Florida. Plasma samples were analyzed using a validated heterologous radioimmunoassay...

Winter biomass and nutrient values of three seagrass species as potential foods for redheads (Aythya americana eyton) in Chandeleur Sound, Louisiana Winter biomass and nutrient values of three seagrass species as potential foods for redheads (Aythya americana eyton) in Chandeleur Sound, Louisiana

We studied biomass and macronutrient content ofHalodule wrightii (shoalgrass) throughout the winter and ofThalassia testudinum (turtlegrass) andSyringodium filiforme (manateegrass) in January in Chandeleur Sound, LouisianaHalodule, the primary fcod of wintering redheads, had the lowest biomass of the three species on the study area in mid-winter. Macronutrient content ofHalodule did not...

Nest monitoring using a micro-video camera Nest monitoring using a micro-video camera

A system is described that utilizes a battery operated micro-video camera mounted on an extendible pole for monitoring high nests. The video image is transmitted to a hand-held monitor at ground level and provides accurate information about the contents of high nests.
