Population genetics of the diamondback terrapin (Malaclemys terrapin).
We examined the population genetic structure of the diamondback terrapins (Malaclemys terrapin), within and among estuaries. Based on mark-recapture studies, these estuarine turtles have high site fidelity that is likely to make them vulnerable to local extinctions. We tested if observed site fidelity of adults would be reflected in intraestuarine population genetic structure of six highly poly...
متن کاملOsmoregulation in the diamondback terrapin, Malaclemys terrapin centrata.
Survival of vertebrates in hypertonic environments such as the sea is opposed by diffusional loss of water and gain of sodium, and is aided by physical barriers to such diffusion along with the ability to transport ions actively. The energy expenditure for active transport obviously must be related to the efficiency of the physical barriers that impede diffusion. The description of these proces...
متن کاملSeasonal changes in thermal environment and metabolic enzyme activity in the diamondback terrapin (Malaclemys terrapin).
Diamondback terrapins experience broad fluctuations in temperature on both a daily and seasonal basis in their estuarine environment. We measured metabolic enzyme activity in terrapin muscle tissue to assess thermal dependence and the role of temperature in seasonal metabolic downregulation in this species. Activity of lactate dehydrogenase (LDH), pyruvate kinase (PK), citrate synthase (CS), an...
متن کاملCentre Sampling for Estimating Elusive Population Size
The estimation of the size of an elusive population is a problem frequently addressed in many fields of applications. In the paper a sampling strategy for the estimation of the size, named centre sampling, is proposed, and its properties are evaluated in a design-based approach. The estimator is admissible, consistent and the design is measurable. The expressions of the variance of the populati...
متن کاملTurtle soup, Prohibition, and the population genetic structure of Diamondback Terrapins (Malaclemys terrapin)
Diamondback terrapins (Malaclemys terrapin) were a popular food item in early twentieth century America, and were consumed in soup with sherry. Intense market demand for terrapin meat resulted in population declines, notably along the Atlantic seaboard. Efforts to supply terrapins to markets resulted in translocation events, as individuals were moved about to stock terrapin farms. However, in 1...
