[Ti] Título:Evolution through cold and deep waters: the molecular phylogeny of the Lithodidae (Crustacea: Decapoda).

[Ab] Resumo:The objectives of this work are to use gene sequence data to assess the hypothesis that the Lithodinae arose from ancestors with uncalcified abdomens in shallow waters of the North-East Pacific, investigate the monophyly and interrelationships of genera within the Lithodinae and to estimate the scale and minimum number of biogeographic transitions from the shallow environment to the deep sea and vice versa. To do this, phylogenetic analysis from three mitochondrial and three nuclear markers was conducted using minimum evolution, maximum likelihood and Bayesian methods. The Lithodinae as defined to include North Pacific genus Cryptolithodes may be paraphyletic, with the Hapalogastrinae and Cryptolithodes as sister taxa. This implies that the soft-bodied abdomen of the Hapalogastrinae might not be plesiomorphic for the Lithodidae. Paralomis, Lopholithodes, Phyllolithodes, Lithodes and Neolithodes share a common ancestor, from which the North Pacific Hapalogastrinae did not descend. Lithodid ancestors are likely to have had a north Pacific, shallow water distribution and to have had planktotrophic larvae. North Pacific genus Paralithodes is paraphyletic; P. brevipes is the most basal member of the genus (as sampled) while P. camtschaticus and P. platypus are more closely related to the genera Lithodes and Neolithodes. Genera Lithodes, Neolithodes and Paralomis (as sampled) are monophyletic if Glyptolithodes is included within Paralomis. Lopholithodes is closely related to, but not included within, the Paralomis genus. Paralomis is divided into at least two major lineages: one containing South Atlantic, West African, and Indian Ocean species, and the other containing Pacific and South American species. Several species of Paralomis do not resolve consistently with any other groups sampled, implying a complex and possibly rapid global evolution early in the history of the genus. Relationships within the Lithodes genus vary between analytical methods, suggesting that conclusions may not be stable. Consistently, however, Indian Ocean and Pacific forms-L. murrayi, L. longispina and L. nintokuae form a group separated from Atlantic species such as L. santolla, L. confundens, L. maja and L. ferox.

[Ti] Título:Opsin Expression in the Central Nervous System of the Mantis Shrimp Neogonodactylus oerstedii.

[Ab] Resumo:Visual pigments, each composed of an opsin protein covalently bound to a chromophore molecule, confer light sensitivity for vision. The eyes of some species of stomatopod crustaceans, or mantis shrimp, can express dozens of different opsin genes. The opsin diversity, along with spectral filters and unique tripartite eye structure, bestow upon stomatopods unusually complex visual systems. Although opsins are found in tissues outside typical image-forming eyes in other animals, extraocular opsin expression in stomatopods, animals well known for their diversity of opsins, was unknown. Caudal photoreception in the central nervous system of decapod crustaceans, a group closely related to stomatopod crustaceans, is thought to be opsin based. However, electrophysiological data suggest that stomatopods do not have caudal photoreceptors. In this study, we identified mRNAs that could encode four different opsins and several components of a potential G -mediated phototransduction pathway in the central nervous system of the Caribbean mantis shrimp Neogonodactylus oerstedii. The four opsins are abundantly expressed in the cerebral ganglion, or brain, with little or no expression in the remainder of the ventral nerve cord. Our data suggest that there are previously undiscovered cerebral photoreceptors in stomatopods.

[Ti] Título:Ecological structure and function in a restored versus natural salt marsh.

[Ab] Resumo:Habitat reconstruction is commonly employed to restore degraded estuarine habitats and lost ecological functions. In this study, we use a combination of stable isotope analyses and macrofauna community analysis to compare the ecological structure and function between a recently constructed Spartina alterniflora salt marsh and a natural reference habitat over a 2-year period. The restored marsh was successful in providing habitat for economically and ecologically important macrofauna taxa; supporting similar or greater density, biomass, and species richness to the natural reference during all but one sampling period. Stable isotope analyses revealed that communities from the natural and the restored marshes relied on a similar diversity of food resources and that decapods had similar trophic levels. However, some generalist consumers (Palaemonetes spp. and Penaeus aztecus) were more 13C-enriched in the natural marsh, indicating a greater use of macrophyte derived organic matter relative to restored marsh counterparts. This difference was attributed to the higher quantities of macrophyte detritus and organic carbon in natural marsh sediments. Reduced marsh flooding frequency was associated with a reduction in macrofaunal biomass and decapod trophic levels. The restored marsh edge occurred at lower elevations than natural marsh edge, apparently due to reduced fetch and wind-wave exposure provided by the protective berm structures. The lower elevation of the restored marsh edge mitigated negative impacts in sampling periods with low tidal elevations that affected the natural marsh. The results of this study highlight the importance of considering sediment characteristics and elevation in salt marsh constructions.

[Ti] Título:Is digestive cathepsin D the rule in decapod crustaceans?

[Ab] Resumo:Cathepsin D is an aspartic endopetidase with typical characteristics of lysosomal enzymes. Cathepsin D activity has been reported in the gastric fluid of clawed lobsters where it acts as an extracellular digestive enzyme. Here we investigate whether cathepsin D is unique in clawed lobsters or, instead, common in decapod crustaceans. Eleven species of decapods belonging to six infraorders were tested for cathepsin D activity in the midgut gland, the muscle tissue, the gills, and when technically possible, in the gastric fluid. Cathepsin D activity was present in the midgut gland of all 11 species and in the gastric fluid from the seven species from which samples could be taken. All sampled species showed higher activities in the midgut glands than in non-digestive organs and the activity was highest in the clawed lobster. Cathepsin D mRNA was obtained from tissue samples of midgut gland, muscle, and gills. Analyses of deduced amino acid sequence confirmed molecular features of lysosomal cathepsin D and revealed high similarity between the enzymes from Astacidea and Caridea on one side, and the enzymes from Penaeoidea, Anomura, and Brachyura on the other side. Our results support the presence of cathepsin D activity in the midgut glands and in the gastric fluids of several decapod species suggesting an extracellular function of this lysosomal enzyme. We discuss whether cathepsin D may derive from the lysosomal-like vacuoles of the midgut gland B-cells and is released into the gastric lumen upon secretion by these cells.

[Ab] Resumo:Description of larvae of three species: Pandalus eous, P. goniurus and P. tridens (family Pandalidae) from planktonic samples taken in the Okhotsk Sea, Avacha Gulf, and in the Bering Sea is given. Morphological features of larvae for the purpose of their identification are compared. Features which are not subject to significant intraspecific variation, and which is useful for the separation of these species in larval period are discussed. The most important features for identification of larvae of these species may be the structure of the rostrum, the presence or absence of denticles on the carapace and abdomen, the number of setae on different legs. The most reliable feature for the separation of larvae of these species into stages of zoea is the structure of the maxilla. A key to identify of species in larval stages and drawings of separate stages are given.

[Ti] Título:Morphological description of early zoeal stages of Alpheus brasileiro Anker, 2012 reared in the laboratory, including a revision of the larval morphology of the first zoeal stage of the genus Alpheus Fabricius, 1798 (Caridea: Alpheidae).

[Ab] Resumo:The aims of this study were to describe and illustrate the early larval stages of the snapping shrimp Alpheus brasileiro Anker, 2012 and to review the larval morphology (Zoea I) of the genus Alpheus Fabricius, 1798. Larvae were obtained from two females with embryos collected in an intertidal estuary in Cananéia, São Paulo state, Brazil. The published descriptions of all available Alpheus zoea I (only 14 spp., 4.7%) were used for a comparison of larval morphology. The zoeae I of Alpheus species are very similar, but A. brasileiro can be separated from the other studied species by the following set of characteristics: antennal scale 5-segmented with 11 plumose setae and 2 simple setae; coxal endite of maxillule with 3 simple setae and 2 sparsely plumose setae; and coxal endite of maxilla with 1 simple seta and 1 sparsely plumose seta. The description of early larval development of A. brasileiro indicates consistent characteristics, which, when analyzed along with other morphological, molecular, and biogeographical aspects, can help to elucidate the complex phylogenetic relationships between the species in the group. However, this is the first zoeal description of a member of Alpheus       armillatus species complex and it therefore does not permit a comparison. Only with new additional descriptions we will be able to generate a clearer scenario in this field due the high similarity among the species.

[Ti] Título:Redescription of the pagurid hermit crab Catapaguroides fragilis (Melin, 1939) and descriptions of two new species from deep-sea off the Ryukyu Islands, Japan (Crustacea: Decapoda: Anomura).

[Ab] Resumo:Three species of the pagurid hermit crab genus Catapaguroides A. Milne-Edwards & Bouvier, 1892, all from Japanese waters, are reported. Catapaguroides fragilis (Melin, 1939) is redescribed on the basis of the holotype and additional material from southern Japan. Diagnostic characters of this poorly known species are fully assessed. Two new species, C. bythos and C. rubromaculatus, are described and illustrated on the basis of material from upper bathyal depths off the Ryukyu Islands. Catapaguroides rubromaculatus n. sp. resembles C. fragilis and C. hirsutus Komai & Rahayu, 2013, but the characteristic shape of the ocular peduncle and the elongate male right sexual tube with an anteriorly directed distal portion readily separate C. rubromaculatus n. sp. from the latter two congeners. Catapaguroides bythos n. sp. appears close to C. mortenseni de Saint Laurent, 1968 and C. pectinipes (Lewinsohn, 1969), but the different armature of the chelipeds distinguishes C. bythos n. sp. from the latter two allies. Catapaguroides is now represented by 30 species.

[Ab] Resumo:Euastacus vesper sp. nov., is described from the upper Cudgegong River, Coricudgy State Forest, New South Wales, Australia. The new species occurs in the western drainage of the Great Dividing Range, and is most closely related to E. spinifer (Heller, 1865), which occurs on the eastern side of the range. Euastacus vesper differs from E. spinifer by its considerably smaller maximum size (OCL 67.9 mm versus 116.7 mm), greater degree of thoracic spination loosely arrayed in three instead of two rows and absence of the antennular basipodite and coxopodite spines. Observations on burrowing, ecological preferences and biology are presented.

[Ab] Resumo:Two new species of freshwater crabs of the pseudothelphusid genus Neostrengeria Pretzmann, 1965, N. fernandezi n. sp., and N. lassoi n. sp., are described. The genus is endemic to the eastern Andes of Colombia. Neostrengeria fernandezi was collected in Las Cacas cave, Pauna, Boyacá Department and N. lassoi in a stream within Los Aviones cave, La Guadalupe, Santander Department, within the cave as well as in a waterfall outside the cave. With the addition of N. fernandezi and N. lassoi the total number of species of the genus Neostrengeria increases to 27. Like all others species of Neostrengeria, the new species are distinguished primarily by the morphology of the first male gonopod, particularly by the form of lateral, accessory and mesial lobes, outline of the apex, and the mesio-caudal projection of the spermatic channel.
