Brief accounts are provided summarizing research efforts on octopus species taxonomy, diversity and distribution in different regions of North and South America. <i>Octopus americanus</i> and <i>O. insularis</i> are compared and clearly distinguished from each other and from the closely-related European species, <i>O. vulgaris</i>. The use of genus names <i>Paroctopus</i> and <i>Pinnoctopus</i> is clarified. Included is a discussion of the recent application of genus name <i>Paroctopus</i> to warm-temperate and tropical species of small size, along with a cautionary note about species identifications in the light of past errors in misassigning large-to-giant cold-water species to genus <i>Paroctopus</i>. Related to problems with identifying species of <i>Paroctopus</i>, there is an appended note concerning misidentifications and the importance of thorough species descriptions to obtain species information at the levels of both phenotype and genotype. A lectotype is formally designated for <i>Bathypolypus arcticus</i> (Prosch, 1849); and the status of so-called ‘<i>Octopus giganteus</i>’ is reviewed briefly. A supplementary online database, AmeriCeph, provides basic information about all known octopus species of the Americas, including the institutional location of type material and the identification of voucher specimens and their depositories. DNA sequences registered in this database are not all fully compatible with barcoding standards. However, a subset of DNA sequences conforming to strict barcode identifications is provided in a second supplementary table, providing barcode sequences directly applicable also to improving standards of seafood traceability. This in turn contributes to building sustainability of exploited octopus fisheries stocks and identification of species suitable for aquaculture trials to meet the increasing commercial demand for octopus worldwide.</p>","PeriodicalId":18365,"journal":{"name":"Marine Biology","volume":"13 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wind influences the mode, height and speed of seabird flight, and therefore the risk of collision with turbines. We investigated how wind influences the flight of black-legged kittiwakes <i>Rissa tridactyla</i>, a gull of conservation concern, in order to incorporate these findings into collision risk estimates and identify mitigation measures. We used GPS telemetry data (23rd June to 10th August 2021) from 20 kittiwakes breeding in Aberdeenshire, UK (57.385°N, 1.868°W) to estimate the effect of wind on behavioural state, proportion of flight at collision risk height, probability of collision when within the rotor-swept zone, and overall collision risk. We found that as windspeed increased, kittiwakes commuted less and rested more. With increasing windspeed, kittiwakes spent a considerably smaller proportion of their flight time in the rotor-swept zone, but had a slightly higher probability of collision while in it. Uncertainty was high for most relationships between windspeed and kittiwake flight metrics. The overall effect of increasing windspeed on collision risk was negative, although we did not model avoidance rate. Effects of windspeed on collision risk were largely mediated through effects on commuting flight, and contingent on wind direction. Collision risk estimates incorporating the effects of windspeed may have greater precision and accuracy, but considerable uncertainty in windspeed-flight parameter relationships remains. Therefore although kittiwake collision risk may be mitigated by raising the ‘cut-in’ windspeed above which wind turbines generate power, the magnitude of this effect is uncertain.</p>","PeriodicalId":18365,"journal":{"name":"Marine Biology","volume":"8 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142185340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective seabird conservation requires an understanding of both seabird distributions and habitat usage. Species distribution models can help identify important areas for protection and manage threats to seabird populations. However, populations of the same species may differ in their response to the environment, reducing the transferability of such models. In addition, individual-level responses to habitat may vary both within and between animal populations. Atlantic Puffins (<i>Fratercula arctica</i>) are classed as vulnerable to global extinction and a UK red-listed bird of concern. Consequently, a greater understanding of their at-sea habitat usage is a conservation priority. We used GPS tracking data from four UK Puffin colonies to construct species distribution models and examine colony- and individual-level variation in habitat usage in response to a suite of environmental covariates (chlorophyll-a concentration, sea surface temperature (SST), water depth, seabed slope, current velocity, and SST front gradient). The most consistent colony-level response was a negative association between habitat usage and chlorophyll-a concentration (observed at 3 out of 4 colonies). Responses to other environmental covariates were less consistent across colonies. Among individual variation in foraging range per trip was low, but we observed individual variation in habitat usage in response to almost all environmental covariates examined. Within each colony, we also identified distinct clusters of space-use across different groups of individuals. Different Puffin colonies and individuals are not ecologically equivalent. Therefore, perturbations to the marine environment are likely to have disproportionate effects on certain colonies and/or individuals. Incorporating colony- and individual-level variation will thus be essential for marine conservation efforts.</p>","PeriodicalId":18365,"journal":{"name":"Marine Biology","volume":"41 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, little is known about how corals calcify under sub-optimal conditions (e.g., turbid waters, high nutrients, sedimentation) or coral growth in understudied regions such as the Colombian Caribbean. We therefore assessed the calcification and linear extension rates of five coral species across an inshore-to-offshore gradient in the Colombian Caribbean. A suite of environmental variables (temperature, light intensity, visibility, pH, nutrients) measured during the rainy season (May – November 2022) demonstrated more sub-optimal conditions inshore compared to offshore. Across all species, calcification rates were 59% and 37% lower inshore compared to the offshore and midshore sites, respectively. Across all sites, massive corals calcified up to 92% more than branching species but were more susceptible to heat stress and sub-optimal inshore conditions. However, branching species had reduced survival due to extreme climatic events (i.e., bleaching, hurricanes). A comparison with published rates for the wider Caribbean revealed that massive species in the Colombian Caribbean grow up to 11 times more than those in the wider Caribbean while branching species generally have similar growth rates, but this finding may have been influenced by fragment size and/or heat stress. Our findings indicate that present-day environmental conditions, coupled with more frequent extreme climatic events, will favor massive over branching species in midshore areas of the Colombian Caribbean. This suggests a possible shift towards faster calcifying massive species in future coral communities, possibly exacerbating the ongoing regional decline in branching species over the last decades.</p>","PeriodicalId":18365,"journal":{"name":"Marine Biology","volume":"22 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142227746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate <i>Bm</i>_<i>GIMAP</i> expression increased under both low light and elevated temperature, suggesting a role in the response to bleaching related stressors. Cultured <i>B. minutum</i> had lower baseline <i>Bm</i>_<i>GIMAP</i> expression than those in association with a cnidarian host, but a stronger response to thermal stress, suggesting their function is influenced by symbiosis. Lastly, further support for the responsiveness of <i>GIMAPs</i> to thermal stress was provided by a comparison with previously published RNA-seq data from cultured Symbiodiniaceae. Collectively, the results presented here represent the first functional investigation of GIMAPs in an ecologically important group of protists and provide a greater understanding of the molecular response of dinoflagellates to stressors related to bleaching.</p>","PeriodicalId":18365,"journal":{"name":"Marine Biology","volume":"9 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
