“…The recruitment period may have changed simply because it is strongly related to the reproductive period. Nonetheless, recruitment in winter could also be a strategy to decrease food competition with other crustaceans that inhabit Ubatuba Bay and are normally more abundant in spring and summer, such as the swimming crabs C. ornatus (Andrade et al., 2014) and A. cribrarius (Silva et al., 2018); the hermit crab Dardanus insignis (Saussure 1858) (Frameschi et al., 2015); and the majoid crab Leurocyclus tuberculosus (H. Milne Edwards & Lucas, 1834) (Bernardes et al., 2016). Thus, by avoiding confrontations with other species, the recruitment of H. pudibundus can be more effective and juveniles can develop faster.…”

“…While P. beringanus is reported to reach sexual maturity in one year (Nyblade, 1974), whether benthic P. granosimanus mirror that life history is unknown, although the two species develop through zoeal and megalope stages at similar rates (Nyblade, 1974). While the maximum lifespan of our study species of hermit crabs appears unknown, other hermit crab species, including a congener, have been reported to live between 18 months and 5 years (Branco et al, 2002;Mantelatto et al, 2005;Frameschi et al, 2015). Therefore, it is likely that our collections contained multiple age classes.…”

We examined the prevalence and shell use of two species of hermit crabs (Pagurus granosimanus and Pagurus beringanus) in exposed and protected microhabitats at five sites in the rocky temperate intertidal on San Juan Island, Washington, to compare present habitat partitioning and potential interspecific competition to that reported nearly 50 years ago. We found that, in contrast to previous findings, the two species of hermit crabs overlapped extensively at some sites, typically those with less wave action. While the hermit crabs typically inhabited certain types of shells significantly more than others, and that use was congruent across microhabitats and species of hermit crabs at the same site, the dominant domicile differed substantially across sites. We provide a more complete ranking of shell use than previous authors and note site-specific dominant shell use. We conclude that previous habitat partitioning by depth may have weakened at protected sites. We hypothesize that increasing temperatures have caused P. granosimanus to expand its range deeper into the intertidal, which may increase the degree of interspecific competition for shells at the edge of the species’ tidal height range, where they overlap. Whether the habitat shift by this hermit crab is due to recent alterations in climate (particularly elevated temperatures, ocean acidification and lower local open ocean salinity) is unknown, but warrants further study.

“…Most decapod species in tropical regions present two types of reproduction: continuous, which occurs all year round (Costa & Negreiro-Fransozo, 1998; Reigada & Negreiros-Fransozo, 2000) and continuous with peaks in some periods (Bertini et al ., 2010 b ; Castilho et al ., 2015; Frameschi et al ., 2015). In temperate regions, reproductive cycles are frequently seasonal (Lancaster, 1990; Gherardi & Cassidy, 1995; Terossi et al ., 2010).…”

We investigated the population dynamics of the spider crab Libinia ferreirae, focusing on the frequency distribution of individuals in size classes, sex ratio and the action of environmental variables (temperature, salinity, texture and organic matter content in the sediment) on reproduction and recruitment. Monthly collections were made in the Ubatuba region from January 1998 to December 2000. A total of 222 individuals were collected, including 123 juveniles (males and females), 43 adult males, 25 non-ovigerous adult females and 31 ovigerous females. Unlike most adult brachyurans, there was no significant size difference between sexes, and sexual dimorphism seems to be a varying characteristic for this crab genus. The reproductive period and recruitment were continuous with peaks that could be related to water mass dynamics and higher food availability in the Ubatuba region. In addition, our results increase knowledge about part of the life cycle of L. ferreirae, which could be useful for comparative studies.
