Fluctuations in the population size of the highly endemic Aegla perobae (Decapoda: Anomura: Aeglidae) caused by a disturbance event

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…”

Diversity and conservation status of Aegla spp. (Anomura, Aeglidae): an update

“…The high rate of endemism presented by many aeglid species, in association with habitat loss/fragmentation or even climatic events, has led many populations to decline (Maia et al, 2013;Bueno et al, 2014). Forty years ago, many species were found in several streams and rivers within a basin, but currently, most of them are restricted to low order creeks (Bond-Buckup and Buckup, 1994).…”

Description of the newly-hatched juvenile of Aegla perobae (Crustacea: Decapoda: Aeglidae)

“…Young juveniles avoid being carried away by the water current by hiding under rocks and pebbles or in shallow areas with low water flow velocity (López 1965). Due to their limited capacity for dispersal, the recruits tend to remain near the parental population (Bueno et al 2014).…”

“…longirostri Bond-Buckup &Buckup 1994 are also available, but the corresponding illustrations were not provided (Bond-Buckup et al 1999). Aegla perobae Hebling & Rodrigues 1977 is endemic to the cuesta of São Pedro, in São Paulo state, Brazil (Hebling & Rodrigues 1977;Rodrigues & Hebling 1978;Bueno et al 2014). The reproductive period occurs during the cold dry period of the year (mid-autumn till late winter) with the production of one single egg batch, and therefore, one single cohort of juveniles per year (Bueno et al 2014).…”

“…Aegla perobae Hebling & Rodrigues 1977 is endemic to the cuesta of São Pedro, in São Paulo state, Brazil (Hebling & Rodrigues 1977;Rodrigues & Hebling 1978;Bueno et al 2014). The reproductive period occurs during the cold dry period of the year (mid-autumn till late winter) with the production of one single egg batch, and therefore, one single cohort of juveniles per year (Bueno et al 2014). Newly-hatched juveniles were obtained by Rodrigues & Hebling (1978) under laboratory condition, but apart from the illustration of the juvenile in dorsal view presented therein, a complete and detailed morphological description is not yet available.…”
