Meeting Abstract
Fundamental and applied studies of protected species require governmental permissions. Permitted studies often have components directed to address conservation data gaps as defined in species recovery plans. Accurate guides for species identification and gross morphology are critical for managers so that subjects are correctly identified. Descriptive and experimental studies that distinguish normal vs. abnormal development, growth, or behavior are knowledge gaps commonly studied by biologists, but not regularly by managers. When declines occur, managers must understand if such changes result from natural or anthropogenic causes. Mistaken blame may result in ineffective management strategies. Several studies link fundamental science and management. Hatchling marine turtles migrate out to sea; how this migration is done differs among species. Some species swim briefly then allow currents to promote offshore displacement; others swim continuously for days. Differences also correlate with contrasts in hatchling size, shape and flipper morphology. Species also differ in visual perception manifested by contrasting structural organization of their retinae, sensitivity to light wavelengths, how visual information is processed during orientation, prey recognition, and other essential functions. Recognition of such differences has helped regulators better address problems associated with artificial lighting at nesting beaches and lights placed on fishing lines and nets that may attract turtles. Recent studies of nest environments improved understanding of the drivers of hatchling sex determination and thus contribute to population sex ratios. Collectively, the studies demonstrate how relationships in structure, function and behavior contribute fundamental knowledge as well as assist in development of better conservation/management strategies.
