“…The ZI larvae of the first species survived at S0 and S5 for 24 hours and 48 hours respectively, without molting to the next stage (present study), and for larvae of M. mordax these salinities are lethal (Martins, 2014). Other fiddler crabs also show similar responses to oligohaline water (low tolerance) for example, M. rapax reported by Simith et al (2014), M. minax by Brodie et al (2007), and M. vocator by Simith et al (2012). This behavior indicates a low level of adaptation to zero or low salinities for fiddler crab larvae.…”

“…In the S35 vessel, the transference was direct, as it had the same salinity as the hatching water. In the remaining treatments (S0, S5, S15 and S25), they were gradually acclimated to lower salinity following Foskett (1977), Charmantier and Charmantier-Daures (1991) and Simith et al (2014).…”

“…From ZIII until M stage, the former food was supplemented with newly-hatched Artemia nauplii (0.6 individuals.ml -1 ), according to the protocol used in larviculture of other fiddler-crab species (Rieger, 1996;1997;1998;1999;Simith et al, 2014). The Artemia nauplii were obtained by decapsulation and incubation following standard methods (Leger and Sorgeloos, 1992;Barbieri and Ostrensky, 2001).…”

The influence of salinity on the survival of the larvae of Leptuca leptodactyla (Rathbun, in Rankin, 1898) from zoea (Z) to megalopa (M) stage was analyzed in order to deduce the larval dispersal strategy of the species. Larvae were obtained from 10 ovigerous females captured in the mangrove of Guaratuba Bay, southern Brazil. Five salinity treatments were conducted from 0 to 35 PSU (S0, S5, S15, S25 and S35). The larvae were individually raised in plastic cell culture plates, totaling 120 experimental units per treatment, kept under natural photoperiod (12:12 h) and constant water temperature (26.3 ± 0.82°C), and fed with microalgae, rotifers and Artemia nauplii. While all larvae died at S0, S5 and S15, complete larval development until the M stage was only observed at S25 and S35. The highest survival rate was recorded at S35 (18 M from 120 newly-hatched Z, survivorship 15%) and the lowest at S25 (2 M, 1.66%). No significant difference in the total duration was observed between S25 (28.5 ± 0.70 days) and S35 (23.61 ± 3.05 days). The life cycle of L. leptodactyla is based on a larval exportation strategy as they need to perform ontogenetic migrations to the coastal area.

“…Studies analyzing the effect of salinity on larval development of decapods are also useful to identify which reproductive strategy is adopted by the species (either retention or exportation) due to the fact that saline limits tolerated by decapod larvae under experimental conditions coincide with their distribution along salinity gradients in the field [113]. In the coastal region of Pará, the effect of salinity on larval development of the crabs Ucides cordatus (Linnaeus, 1763), Uca vocator (Herbst, 1804), and Uca rapax was analyzed in the laboratory, obtaining decreased survival rates under lower salinity conditions, thus indicating a strategy of larval dispersal and exportation [115][116][117][118].…”

The thalassinideans comprise the infraorders Axiidea and Gebiidea, two distinct groups of decapods that have converged morphologically and ecologically as burrowing forms, commonly known as mud lobsters and mud or ghost shrimps. These groups are an important component of the macroinfauna of intertidal and subtidal environments and are distributed throughout the world, with species diversity increasing from high latitudes toward the equator. These species are burrowing benthic decapods, with more than 95% of species inhabiting shallow waters in marine and estuarine environments, exerting considerable influence over the structure of benthic communities through their ability to bioturbate the sediments, with effects on the infauna and seagrasses in coastal environments. Upogebia vasquezi has an ample geographic distribution, it is typically found in rocky outcrops near mangroves. This species reproduces year round, which is subjected to strong seasonal fluctuations in salinity due to the local precipitation regime. The Amazon Macrotidal Mangrove Coast, representing 10% of the Brazilian coastline and encompassing more than 56% of the country's mangrove forests, is a high priority area for conservation. This chapter aims to elucidate the reproductive traits of U. vasquezi with a revision about the known ecological information available for thalassinidean species all over the world.

“…In these case, early zoeae and megalopae are euryhaline and later zoeal stages are stenohaline (Costlow et al, 1966;Cronin, 1982;Anger, 1991;Charmantier et al, 2002;Anger et al, 2008). Furthermore, interspecific variation is known for the low salinity tolerance of newly hatched larvae in phylogenetically related species with export strategy (Anger et al, 2008;Smith et al, 2014), for instance, in congeneric sesarmid crabs of the genus Armases Abele, 1992, the low salinity tolerance limit for survival was lower in A. roberti H. Milne Edwards, 1853 larvae that hatch in riverine water than A. ricordi H. Milne Edwards, 1853 larvae that hatch in estuarine sea (Anger et al, 2008). Information of the low salinity tolerance for larval survival could thus assist us in inferring the early life-history traits of decapod crustacean species.…”

Tolerance of low salinity by larvae in six terrestrial hermit crab species (Decapoda: Anomura: Coenobitidae)

et al. 2018

Salinity is an important ecological factor affecting larval survival and development of coastal and estuarine decapod crustaceans. We investigated the low salinity tolerance limits of larvae in the six terrestrial hermit crab species, the coconut crab Birgus latro, and the land hermit crabs Coenobita brevimanus, C. cavipes, C. purpureus, C. rugosus, and C. violascens to infer their early life history strategies. Zoeae and megalopae were exposed to six different salinity levels ranging from 5-30 ppt with intervals of 5 ppt for 24 h, and the median lethal salinity (MLS) was estimated as the salinity at which 50% of test larvae died. The MLS estimates were lowest in the first zoeae, increased during the zoeal stage, and declined in the megalopal stage in all species. Early zoeae and megalopae were euryhaline and later zoeae stenohaline, suggesting that coenobitids exhibit a larval export strategy towards the offshore (oceanic) marine waters. Interspecific variation was evident in the salinity tolerance of the first zoeae, probably reflecting the salinity conditions at the species-specific larval hatching place. In contrast, the low salinity tolerance ability of megalopae did not differ among species, suggesting that coenobitid megalopae might require similar habitats for the settlement and initiation of benthic life.
