    Opis:
    The Chinese mitten crab Eriocheir sinensis Milne-Edwards, 1854 is a newcomer to the Baltic Sea. Previous studies have shown that since the 1940s single large specimens of this species have been caught annually in Polish waters. The invasion of the Chinese mitten crab has been reported from many European countries, including Poland, where it is especially abundant in the Odra Estuary. Of 186 specimens captured in Lake Dąbie in August 1998, 45% were females and 55% males. The carapace width of these crabs varied between 53 and 88 mm and the average wet weight was 169±45.3 g.

    Opis:
    Eriocheir sinensis H. Milne-Edwards, 1853 is a non-native species found in European waters. Analyses of mitten crabs caught in brackish waters (Gulf of Gdańsk, Poland) and in freshwater (Havel River, Germany) have indicated that numerous epibionts (possibly temporary) inhabit the dense setal mats that cover the chelipeds. Of the 950 associates found on 22 crabs collected from brackish water, the most abundant were Nematoda (82.3%), followed by Bivalvia (10.3%), Crustacea (5.6%), Oligochaeta (1.2%) and Gastropoda (0.6%). In comparison, 1280 specimens (Chironomidae – 67.6% and Halacaridae – 32.4%), were identified from 13 crabs collected in freshwater. As this crab can migrate long distances, it is capable of transporting native and non-native species via its mittened claws to new habitats.

    paguroid carapace
    Opis:
    On the basis of carapaces, three new genera and species of symmetrical paguroid anomurans are described. Diogenicheles theodorae, Masticacheles longirostris, and Pilgrimcheles karolinae constitute the oldest known members of the family Parapylochelidae. As noted previously, assemblages from sponge−reefal strata of Oxfordian (Late Jurassic) age in the southern Polish Uplands document an important radiation event amongst paguroids. Compared to the present day, the Parapylochelidae were more diverse during the mid−Mesozoic; they appear to have withdrawn from shallow, reefal waters to deep−water settings from the Late Jurassic onwards. Paguroid faunas from the Oxfordian of Europe already are highly diverse, both morphologically and phylogenetically, and comprise early members of the families Diogenidae, Pylochelidae, and Parapylochelidae. This suggests that the evolutionary history of paguroids started much earlier (i.e., in pre−Jurassic times) than previously assumed. New terms for several typical paguroid carapace regions are introduced and on the basis of carapace morphology and ecological shifts hypotheses on the early speciation of hermit crabs are put forward.

    Opis:
    Marine invertebrates depend upon antimicrobial peptides (AMPs) as a major component of innate immunity, as they are rapidly synthesized and diffuse upon pathogen invasion. In this study, we report the identification and characterization of a 11 kDa antimicrobial protein, which we name SSAP (for Scylla serrata antimicrobial protein), from granular hemocytes of the mangrove crab S. serrata. The protein is highly similar to scygonadin, a male-specific AMP isolated from the ejaculatory duct of S. serrata. SSAP was isolated using various chromatographic techniques, viz. ion-exchange, ultra filtration and RP-HPLC, and demonstrated antibacterial activity against Gram positive and Gram negative bacteria. Full length mRNA encoding SSAP was amplified using a combination of RT-PCR and RACE. The nucleotide sequence revealed a full-length ORF of 381 bp coding for a preprotein of 126 amino acids comprising a signal peptide of 24 amino acids and a mature protein of 102 amino acids with a predicted mass of 11435 Da and pI of 5.70. Unlike scygonadin, SSAP is expressed in several tissues of both male and female crabs, as evidenced by RT-PCR, Northern and Western blot analyses. The study suggests that SSAP might be an isoform or a variant of scygonadin and might play an important role in regulating the immunity of the crab upon microbial infection.

    Opis:
    The Bahia Blanca Estuary includes a large tidal plain with an area close to 1150 km2.Mud is predominant in its sediments, where a significant population of the crab Chasmagnathus granulata lives during the whole year.Mo reover, there are important urban and industrial discharges into this environment. Cd and Pb concentrations were determined in samples of water (for both dissolved and suspended particulate matter) and surface sediments (total and <63 μm fractions).Or ganic matter was analysed in the sediments, while temperature, salinity, pH and dissolved oxygen were measured in the estuarine water The metal concentrations determined in this study were: 1.47 ± 1.08 μg Cd g−1 and 14.68 ± 4.31 μg Pb g−1 in surface sediments; 2.21 ± 1.33 μg Cd g−1 and 25.70 ± 7.09 μg Pb g−1 in the <63 μm sediment fraction; 0.18 ± 0.11 μg Cd g−1 and below the analytical detection limit of Pb in suspended particulate matter. Furthermore, dissolved Cd and Pb were lower than the norms for marine and estuarine waters (2 μg dm−3 for Cd and 5 μg dm−3 for Pb, E.P.A.). Simultaneously, the effects of Cd and Pb were studied on recently hatched larvae of Ch. granulata, through 96-hour semi-static acute assays.Via bility was the criterion assessed in the assays.LC 50 (96 h) for Cd was 46.43 μg dm−3 (36.92 − 56.34 μg dm−3), whilst that for Pb was 1. 0 mg dm−3 (0.79 − 1.23 mg dm−3), which demonstrates that Cd is more toxic towards larvae.F inally, both LC50 values determined for Cd and Pb were higher than the corresponding metal concentrations measured in the Bah´ıa Blanca environment.
