Evidence from some regions indicates that global warming may already be increasing the proportion of female hatchlings, but this trend may not be uniform across all areas. Therefore, it is fundamental to understand the spatiotemporal diversity of sand temperature profiles and hatchling sex ratios within each rookery when developing conservation measures. The Ogasawara Islands (27°1′–11′ N, 142°9′–14′ E), Japan, are a highly isolated oceanic archipelago and one of the most important rookeries for green turtles (<i>Chelonia mydas</i>) in the North Pacific. The islands show high inter-beach environmental differences, but to date no study has assessed how these differences translate into spatiotemporal diversity of sand temperatures and hatchling sex ratios. In the present study, we measured the sand temperature at different depths and estimated the hatchling sex ratios from the thermal profiles at seven important nesting beaches of the green turtle in the Ogasawara Islands during 2018–2019. Results showed a marked spatiotemporal diversity in sand temperatures, with estimated hatchling sex ratios varying from male-biased to female-biased among the seven beaches. The spatiotemporal diversity is likely associated with the environmental characteristics between beaches, such as degree of shading, ground vegetation cover, and sand color, as well as seasonal temperature shifts. Nest depth is likely irrelevant for estimating hatchling sex ratios in the Ogasawara Islands. Continuous monitoring of the nesting environments is needed for efficient conservation of green turtle resources.</p>\u0000 </div>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564896","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, like fish, invertebrate organisms play key roles in food webs, both as consumers and as predators. Here, we aimed to provide an integrated overview of the relative trophic position, segregation, and overlap of all main groups of species constituting the deep-pelagic micronektonic community. Stable nitrogen (δ¹⁵N) and carbon (δ¹³C) isotope compositions have thus been measured in 13 species belonging to three groups (jellyfish, crustaceans, and cephalopods) sampled in the Bay of Biscay slope area (Northeast Atlantic), as proxies for trophic level and feeding habitat of species. The addition of published isotopic data from deep-pelagic fish sampled in the same zone also allowed the inclusion of vertebrates in the analyses of the trophic structure of the community. The invertebrate community exhibited wide ranges of δ¹⁵N and δ¹³C values (6.45‰ and 2.71‰, respectively). Cephalopods appeared to segregate along a continuum of δ¹⁵N values, with important differences between muscular and fast-swimming species (<i>Histioteuthis reversa</i> and <i>Todarodes sagittatus</i>) presenting higher δ¹⁵N values than gelatinous species (<i>Teuthowenia megalops</i> and <i>Haliphron atlanticus</i>). In contrast, crustaceans appeared to have lower δ¹⁵N values and to be more strongly segregated by δ¹³C values, suggesting different feeding habitats (range δ¹³C = 2.71‰). Some species showed more pelagic (¹³C-depleted) signatures (e.g., <i>Meganyctiphanes norvegica</i>) while others showed ¹³C-enriched values, possibly corresponding to a more benthopelagic diet (e.g., the two Pasiphaeidae species). Isotopic niche calculations at the group level revealed important overlaps between cephalopods and fish, as well as between jellyfish and crustaceans. These results are of significant importance for understanding the complex functioning of growing interest deep-pelagic food webs on slope areas, by promoting a multi-<i>taxa</i> approach.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/maec.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the results provide initial evidence that <i>L. hyperborea</i> contains substances that are toxic to copepods, an observation that warrants further research. Pelagic copepods consuming kelp detritus would constitute a largely undescribed pathway of carbon from benthic primary producers to the pelagic food web, and a trajectory for deep-sea carbon sequestration.

This area is within the Loch Sunart to Sound of Jura Marine Protected Area (MPA) and designated for the protection of the critically endangered flapper skate (<i>Dipturus intermedius</i>).

Each area was surveyed twice over 2 days in October 2020 and twice in 2 days in May June 2021. One day used bait on the seabed (October) whilst all the others had no bait.

Atlantic salmon (<i>Salmo salar</i>) smolts from the Dale River were tagged with prediction sensor acoustic transmitters and released at one of six sites within the fjord, which was covered by several receivers up to a large bridge across the fjord.

There was a strong effect of release distance on survival, suggesting that releasing the fish further out in the fjord and closer to the bridge improved survival. Mark-recapture analysis revealed the importance of the predation sensors for calculating survival; without using the information from predation sensors, survival through the system was high and the confidence bands were narrow; however, knowing which individuals had been eaten reduced estimated survival substantially.
