Population size of Aegla paulensis (Decapoda: Anomura: Aeglidae)

We used the Schumacher-Eschmeyer method for closed populations to estimate and compare the population size of adults of Aeglapaulensis, from Jaraguá State Park (São Paulo, Brazil), in two periods of the year with contrasting climatic conditions (late winter and late summer). The calculated density o...
