Ciclo reprodutivo do mexilhão Perna perna (Linnaeus) (Molusca, Bivalvia) da Lagoa de Itaipu, Niterói, Rio de Janeiro, Brasil

Temporal variation in intertidal community recruitment and its relationships to physical forcings, chlorophyll-a concentration and sea surface temperature

“…During these periods, even if oceanographic conditions favor larval transport to the shore, recruitment will be low. Perna perna reproduces seasonally in the study region, mostly in May, August and October (Mesquita et al 2001), and this species most likely represented the bulk of larvae that recruited in our study. Focus on reproductive timing may provide a better understanding mussel recruitment variability.…”

Unlocking the history of a trans‐Atlantic invader: Did the human slave trade impact Brown mussel dispersal?

“…The mutation rate used was 10 −4 , as has previously been described as the best estimate for microsatellites (Inoue et al, 2014;Sun et al, 2012;Whittaker et al, 2003) which is orders of magnitude greater than typical nucleotide substitution rates of 10 −8 , due to replication slippage of microsatellite loci (Sun et al, 2012). To convert generations to years before present, we used two different estimates for generation time: one year, as suggested by other studies (Cunha et al, 2014;Oliveira et al, 2017) and six months, a more conservative estimate given that P. perna typically spawn twice a year and are reproductively active as early as three months (Lunetta, 1969;Mesquita et al, 2001).…”

Variation in recruitment rates of rocky shore intertidal invertebrates in response to alterations in physical forcings, chlorophyll-a concentration and temperature: the effect of cold fronts

“…October (MESQUITA et al, 2001), and this species most likely represented the bulk of larvae that recruited in our study. Focus on reproductive timing may provide a better understanding mussel recruitment variability.…”

“…T. stalactifera show maximum breeding in summer months (North part of the study region, SKINNER et al, 2011). Bivalves reproduce seasonally: Perna perna, mostly in May, August and October, when maxima occur (LUNETTA, 1969;MESQUITA et al, 2001;FERREIRA and MAGALHÃES, 2004).…”
