Reproductive Biology in Females of Aegla strinatii (Decapoda: Anomura: Aeglidae)

Allometric growth, sexual maturity and reproductive cycle of Aegla castro (Decapoda: Anomura: Aeglidae) from Itatinga, state of São Paulo, southeastern Brazil

“…In the present study, the population of A. castro from Itatinga shows marked seasonal reproductive period lasting for 5 months (April-August), which is in accordance to the pattern of latitudinal variation of breeding period duration as proposed by Bueno and Shimizu (2008) and supported by similar findings from works published later on for other aeglid species (Rocha et al, 2010;Cohen et al, 2011;Grabowski et al, 2013;Bueno et al, 2014;Chiquetto-Machado et al, 2016). This result, however, is 2.5 times longer than…”

“…This pattern is coherent with those observed in A. franca, A. strinatii Türkay, 1972, A. paulensis Schmitt, 1942 andA. schmitti, species from low latitude locations which become functionally mature at 19-21 months of age (Bueno and Shimizu, 2008;Rocha et al, 2010;Cohen et al, 2011;Chiquetto-Machado et al, 2016). As expected from their faster individual growth, species from higher latitude locations attain functional maturity earlier in their respective life cycle, as reported for A. platensis (12.6-15.6 months) and Aegla longirostri Bond- Buckup and Buckup, 1994 (8 and 12 months) Colpo et al, 2005;Silva-Castiglioni et al, 2006).…”

“…Temporal variation in the proportions between morphotypes in relation to the reproductive cycle of the species indicated that morphotype II males were associated with the acquisition of functional maturity in that sex. For females, the occurrence of full ovarian maturation and/or ovigerous condition have been employed in the determination of the size of functional maturity of aeglid species (Swiech-Ayoub and Masunari, 2001b;Viau et al, 2006;Bueno and Shimizu, 2008;Rocha et al, 2010;Grabowski et al, 2013).…”

Extension of the known distribution of Aegla strinatii Türkay, 1972 and a checklist of decapod crustaceans (Aeglidae, Palaemonidae and Trichodactylidae) from the Jacupiranga State Park, South of São Paulo State, Brazil

“…Thus, the present report represents a new record of A. strinatii from São Paulo State. The species is troglophile, that is, self-sustained populations are found inside and outside caves, with free transit between both environments (Rocha and Bueno, 2004;Rocha et al, 2010). However, it is important to emphasize that no specimens of A. strinatti were found in the Ostras stream after its resurgence from Tapagem Cave (Table I).…”

“…Currently, ten aeglid species have been reported from the State of São Paulo (Rocha and Bueno, 2004) where some of them show high endemism, and inhabit karstic regions, as in the Ribeira do Iguape River Basin (Rocha et al, 2010).…”
