“…These examples may suggest that within limits temperature has a more pronounced eVect on larval morphology than genetic deviation. This is supported by the circumstance that C. setosus exhibits very little genetic diversity along its entire distribution range (Gomez-Uchida et al 2003).…”

Temperature effects on zoeal morphometric traits and intraspecific variability in the hairy crab Cancer setosus across latitude

Phenotypic plasticity is an important but often ignored ability that enables organisms, within species-speciWc physiological limits, to respond to gradual or sudden extrinsic changes in their environment. In the marine realm, the early ontogeny of decapod crustaceans is among the best known examples to demonstrate a temperature-dependent phenotypic response. Here, we present morphometric results of larvae of the hairy crab Cancer setosus, the embryonic development of which took place at diVerent temperatures at two diVerent sites (Antofagasta, 23°45Ј S; Puerto Montt, 41°44Ј S) along the Chilean Coast. Zoea I larvae from Puerto Montt were signiWcantly larger than those from Antofagasta, when considering embryonic development at the same temperature. Larvae from Puerto Montt reared at 12 and 16°C did not diVer morphometrically, but sizes of larvae from Antofagasta kept at 16 and 20°C did, being larger at the colder temperature. Zoea II larvae reared in Antofagasta at three temperatures (16, 20, and 24°C) showed the same pattern, with larger larvae at colder temperatures. Furthermore, larvae reared at 24°C, showed deformations, suggesting that 24°C, which coincides with temperatures found during strong EL Niño events, is indicative of the upper larval thermal tolerance limit. C. setosus is exposed to a wide temperature range across its distribution range of about 40° of latitude. Phenotypic plasticity in larval oVspring does furthermore enable this species to locally respond to the inter-decadal warming induced by El Niño. Morphological plasticity in this species does support previously reported energetic trade-oVs with temperature throughout early ontogeny of this species, indicating that plasticity may be a key to a species' success to occupy a wide distribution range and/or to thrive under highly variable habitat conditions.

“…Sex-linked markers have been found in males of the isopod Mysis relicta [45] and of Triops cancriformis [46]. In female crustaceans, sex-linked markers have been found in the isopods Paracerceis sculpta [47] and Jaera ischiosetosa [48], in the crab Cancer setosus [49], in penaeid shrimps L. vannamei [41] and P. monodon [27] and in giant freshwater prawn M. rosenbergii [50]. Moreover, a hermaphrodite-determining allele has been studied in the androdioecious branchiopod E. texana [51].…”

A first AFLP-Based Genetic Linkage Map for Brine Shrimp Artemia franciscana and Its Application in Mapping the Sex Locus

We report on the construction of sex-specific linkage maps, the identification of sex-linked markers and the genome size estimation for the brine shrimp Artemia franciscana. Overall, from the analysis of 433 AFLP markers segregating in a 112 full-sib family we identified 21 male and 22 female linkage groups (2n = 42), covering 1,041 and 1,313 cM respectively. Fifteen putatively homologous linkage groups, including the sex linkage groups, were identified between the female and male linkage map. Eight sex-linked AFLP marker alleles were inherited from the female parent, supporting the hypothesis of a WZ–ZZ sex-determining system. The haploid Artemia genome size was estimated to 0.93 Gb by flow cytometry. The produced Artemia linkage maps provide the basis for further fine mapping and exploring of the sex-determining region and are a possible marker resource for mapping genomic loci underlying phenotypic differences among Artemia species.

“…Using allozymes and amplified fragment length polymorphisms, Gomez-Uchida et al (2003) reported genetic homogeneity over 2500 km of the Chilean coast for the hairy edible crab Cancer setosus, which the authors attributed to its long-lived planktonic larval stage (60 d). Similar lack of genetic structure along major parts of the Chilean coast has been reported for the Chilean abalone Concholepas concholepas (Gallardo & Carrasco 1996, Cárdenas et al 2009), the blue mussel Mytilus chilensis (Toro et al (Galleguillos et al 2000).…”
