Fasted and starved crabs were better adapted to deal with hypoxia than fed animals; however, avoidance behavior is usually considered as the first defense to environmental stressors for decapod crustaceans. We examined the effects of food deprivation on the crab’s behavior to hypoxia using the Loligo® shuttle box system, an automated system with a pair of connected water chambers with regulated flow and oxygen level. Crabs (starved, fasted and fed) that were offered a choice of two different oxygen saturations did not appear to actively avoid the hypoxia regimes tested (50% and 20% oxygen saturation). We used novel algorithms to analyze the data and found that crabs altered rheotaxis (movement towards or away from a current of water) and corresponding moving speed as a function of oxygen saturation. The food-deprivation state did influence thigmotaxis (contact with walls/objects when exploring an open space): starved crabs became bolder and more likely to explore open areas of the apparatus. Technological advancements such as the fully automated shuttle box have improved our ability to collect and analyze behavioral data; however, our study also highlighted some of the potential problems of relying solely on such apparatus to study the behavior of benthic crustaceans.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49303967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decapod crustaceans, being deposit-omnivorous feeders, are appropriate biological models to assay the biological effects of NMs. The present study evaluated the effects of ZnO and multi-walled carbon nanotubes (MWCNTs) NMs separately and in combination on the activities of antioxidant enzymes on crustacean hyperglycemic hormone (CHH), hematology, reproductive performance, and hepatopancreas lesions the Oriental river prawn, Macrobrachium nipponense De Haan, 1849 [De Haan, 1833–1850]. We essayed concentrations of ZnO (0, 1, 10, 30, 50 mg l–1) and MWCNTs (0, 5, 10, 15, 20 mg l–1) and two higher concentrations of the NMs were compared in combined treatments. Both NMs showed dose-dependent effects on reproductive parameters of M. nipponense, especially the fertilization rate of eggs. Inter-molt and inter-spawn periods were postponed and reproduction stopped in 50 ppm ZnO and 15 and 20 ppm MWCNTs treatments. Our findings showed that the release of crustacean hyperglycemic hormone (CHH) and superoxide dismutase (SOD) enzyme activity are directly related to the NMs levels independently as well as in combination. NMs did not show any effect on the activities of alanine transaminase (ALT) and aspartate transaminase (AST) enzymes in muscle tissue independently, but the combined effects of the activities of these enzymes were significant. NMs caused hepatocyte enlargement, melanization, apoptosis, and necrosis damages in the hepatopancreas of prawns. The findings showed that ZnO and MWCNTs NMs have strong adverse biological effects on M. nipponense, and that this species is an appropriate bio-indicator and bio-monitor organism for NMs contaminations in the freshwater aquatic environments.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135802421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is mainly synthesized by trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP), and degraded by trehalase (TRE). In the present study, the tps, tpp, and tre were identified from various crustacean species and their phylogeny, structure, network, and transcriptome were analyzed. The tps and tpp are fused in crustaceans, accompanied with multi-copies of genes to improve the synthesis capacity of trehalose, and they may be formed by whole-genome duplication (WGD) and/or segmental duplications. Phylogenetic subgroups of enzymes in the same species may be due to the different lengths and distribution positions of domains. The protein with single TPP domain in the salmon louse, the copepod Lepeophtheirus salmonis (Krøyer, 1837), probably has a depoisoning effect. Structure analyses and location predictions showed that crustacean TRE possess an α-helix-rich structure with barrel core, and are membrane-bound, cytoplasmic, and secreted. Additionally, the non-acid TRE might not be adjusted by Ca2+ because there is no binding domain in crustaceans. Expression profiles of different tissues, developmental periods, and environmental-challenge responses, as well as genes of co-expression networks suggested that TPS (including TPP) and TRE might play important roles in physiological activities including development and environmental adaptation in crustaceans. Multi-copies of tre may enhance survival ability of copepods in diverse and sometimes harsh environments. Branchiopods, copepods, and the marine shrimp Penaeus vannamei Boone, 1931 are suspected to adopt possible acid TRE as a supplementary strategy in response to stress.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43254207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Podotrematous crabs suffered high extinction levels, whereas heterotrematous crabs experienced both extinction and radiation. Anomuran decapods exhibited high extinction levels at the generic but not family level. In general, family extinctions predominantly occurred among podotrematous and heterotrematous crabs, which also exhibit overall shorter family ranges. Possible refugia promoted survival of genera and families into the Paleocene, whereas habitation of the Western Interior Seaway ensured high levels of extinction. Areas proximal to the Chicxulub impact site experienced moderate levels of extinction. Habitat specialists preferentially survived the end-Cretaceous extinction in some clades. Heterotrematous crabs recovered rapidly in the Paleocene, especially in the siliciclastic environments of the Americas. Because decapod crustaceans are highly variable in morphology, habitat, and ecology, no one pattern of extinction and recovery can explain the end-Cretaceous decapod extinction event. Rather, a mosaic of responses in various decapod groups led to their differential survival.","PeriodicalId":54850,"journal":{"name":"Journal of Crustacean Biology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44853714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
