For Gecarcinidae crabs there are few studies on reproductive behaviour, and are especially rare for isolated species, as in the genus Johngarthia. Here, we describe the mating behaviour of the endangered insular crab J. lagostoma endemic of the South Atlantic Ocean, with a focus on pre-, copulatory, and post-copulatory behaviours. Observations were made on 20 pairs in the field, with every female in intermoult. Accessory behaviours were absent, with copulation beginning after sexual recognition. After mating, there were no records of males guarding or embracing females. All couples had the female in an upper position and passive males, which do not react when other males are near the mating site. The size of the chelipeds and males were random and not determinant to mating. However, yellow crabs predominated (95%) in mating pairs and the linkage of colouration to sexual selection needs to be more elucidated because purple crabs are less frequent in the population and the lower representation in the couples can be an effect of this. Experimental studies are required to investigate sexual selection and the occurrence of the behaviour described herein at other locations.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"65 1","pages":"256 - 267"},"PeriodicalIF":0.8,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48610538","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}

The average incubation period of eggs, developmental durations of instars I–V and total developmental time were significantly less at warm temperature (wet season) than in cold temperature (dry season). However, the hatching percentage was significantly higher at warm temperature than in cold temperature. Morphometric measurements of nymphs and adults were also significantly less at warm temperature than in cold temperature. Laboratory reared individuals during the wet season at warm temperature had faster development and produced smaller individuals as compared with the dry season. The developmental durations and body size of the experimental individuals were significantly negatively correlated with rearing temperature. The study further revealed that in warm temperature the developmental duration of the experimental individuals become shorter which in turn might increase the number of generations of this insect.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"65 1","pages":"246 - 255"},"PeriodicalIF":0.8,"publicationDate":"2021-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07924259.2021.1961884","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47897170","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}

However, its planktonic larvae occur at depths shallower than 300 m. To better understand the factors influencing larval dispersal and settlement of the red snow crab in its natural habitat, we tested the effects of temperatures ranging from 1°C to 18°C on the survival, developmental period, and growth of red snow crab zoeal and megalopal larvae. The mean number of days from hatching to second zoeae and megalopae and from megalopae to the first crab instar was significantly shorter at warmer temperatures. Moreover, the relationships between mean temperatures and larval periods were well described by heat summation theory equations and a nonlinear thermodynamic Sharpe-Schoolfield-Ikemoto (SSI) model. The higher survival rate, intrinsic optimum temperatures in the SSI model, and larger carapace width suggested that the optimum temperatures for the development of zoeal and megalopal stages of the red snow crab are 9–10°C and 7–8°C, respectively. A lower optimum temperature in the megalopal stage than in the zoeal stages was considered an adaptation to facilitate deeper vertical distributions in the megalopal stage.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"65 1","pages":"235 - 245"},"PeriodicalIF":0.8,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46112640","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}

In this study, a full-length cDNA of GnRH-like gene from the cuttlefish Sepia pharaonis (denoted as SpGnRH, GenBank Accession NO. QPB69198.1) was cloned, which is 432 bp and the open reading frame (ORF) encodes a protein of 90 aa. Multi-sequence alignment revealed high homology of SpGnRH with GnRH from other cephalopod species: 99%, 91%, 86% and 71% similarity with Sepia lycidas, Sepiella japonica, Uroteuthis edulis and Octopus vulgaris, respectively. Phylogenetic analysis supported the finding that SpGnRH was a new member of the GnRH protein family, which was clustered into a group with octopus, squid, and other cuttlefish species. Tissue distribution analysis revealed that SpGnRH mRNA was highly expressed in the brain at three developmental stages (stage III, stage IV, and stage V). In situ hybridization showed that SpGnRH was localized throughout several different functional brain lobes, suggesting SpGnRH might be involved in physiological regulations such as reproduction and feeding. This study might provide a useful theoretical basis for studying reproductive regulation, genetic resource conservation, and artificial breeding.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"65 1","pages":"226 - 234"},"PeriodicalIF":0.8,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07924259.2021.1935335","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47930445","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}

Marine heatwaves that occur in spring and summer may coincide with the developmental timing of sensitive early life-history stages of benthic marine invertebrates. The successful development of these early life stages, along with other physical and biological factors, will determine the abundance of benthic populations. Here, we examine the effects of a laboratory-simulated marine heatwave on early development (fertilization and embryonic cleavage) in the sea urchin Arbacia punctulata taken from its cold (northern) range edge in the Northwest Atlantic. We predicted that a marine heatwave would yield accelerated development given that ambient temperatures at this cold range edge are likely suboptimal for development of A. punctulata. Consistent with this hypothesis, we observed faster fertilization and cleavage rates in a marine heatwave treatment (27.5°C) as compared to an ambient temperature treatment (21.8°C) within the first 3 hours of development. The results contribute to our understanding of how marine heatwaves can affect the earliest life stage of A. punctulata.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"65 1","pages":"219 - 225"},"PeriodicalIF":0.8,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07924259.2021.1933222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47172438","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}

Fecundity for each size class was also determined for wild colonies. Both sexually propagated and wild F. abdita colonies that are 1.8 cm in diameter were found to be sexually mature.
