Snails from wave-exposed areas commonly have more streamlined shells that reduce drag forces with larger openings that favor their attachment to the substrate. In contrast, snails from sites with high predation commonly have a more globose shape that hinders breakage by predators. Hermit crabs use the shells of dead snails to protect their soft abdomen and confront similar biotic and abiotic pressures. Our main goal was to determine whether hermit crabs exploit intraspecific variation in snail shell shape in ways that may be adaptive; we tested two snail species with different shell profiles (<em>Mancinella</em> = globose-like and <em>Stramonita</em> = streamlined) across two intertidal zones. Using geometric morphometrics, we compared the shape and size of shells of snails with those used by hermit crabs in the upper and mid intertidal zones. We found that shell shape differed depending on the type of organism and the intertidal zone they inhabit. <em>Mancinella</em> shell shape was similar between snails and hermit crabs in the mid intertidal, and <em>Stramonita</em> shells were similar between crabs and snails in the upper intertidal. However, the shell shape differed between snails and hermit crabs in <em>Mancinella</em> shells in the upper intertidal and <em>Stramonita</em> shells in the mid intertidal. Furthermore, in the upper intertidal, hermit crabs occupied the most extreme shapes of each snail species, the most globose <em>Mancinella</em> and most streamlined <em>Stramonita</em> shells. Thus, although both taxa are subject to similar pressures on shell shape, different constraints result in some shape similarities and contrasts among species depending on the intertidal zones they inhabit.</div></div>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"208 ","pages":"Article 107141"},"PeriodicalIF":3.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the characteristics of newly documented tropical oyster reefs across three Australian locations to gain a foundational understanding of their ecology. At each location, structural reef traits were assessed, and associated invertebrate communities were quantified taxonomically and functionally. Location had a strong effect on invertebrate communities, with reefs in Gladstone hosting a greater abundance, and larger, invertebrates, followed by Mapoon, and then Proserpine. Most invertebrates were positively associated with the lower intertidal zone and shelly sediment – we hypothesise that heat stress, interstitial reef spaces, and the proportion of habitat edges could be explanations for these observed patterns, however, further research is needed to confirm this.

Macroalgae are then degraded by fish gut microbiota. Despite the importance of this process, there remains a lack of information about the gut bacterial community of herbivorous fishes in coral reefs. This study examined the composition and potential metabolic functions of gut microbiota through full-length 16S rRNA amplicon sequencing for coral reef fish species from the Xisha islands of China, including five herbivorous species (<em>Naso unicornis</em>, <em>N. lituratus</em>, <em>N. brevirostris</em>, <em>Ctenochaetus striatus</em>, and <em>Siganus argenteus</em>) and one carnivorous species (<em>Myripristis kuntee</em>). The composition of the gut bacterial community and potential functional genes were observed and significant differences were identified between herbivorous and carnivorous fish species. The bacterial diversity (Shannon and Simpson indexes) in herbivorous fish was significantly higher than in carnivorous fish. <em>Clostridium</em> was significantly more abundant in carnivorous fish than herbivorous fish (<em>p</em> &lt; 0.05). Conversely, <em>Niameybacter</em>, <em>Alistipes</em>, <em>Desulfovibrio</em>, and <em>Akkermansia</em> were more abundant in herbivorous fish (<em>p</em> &lt; 0.05). These bacterial genera, which are shared among herbivorous fish, are believed to play crucial roles in macroalgae metabolism. A principal coordinate analysis further revealed that the gut bacterial composition of the five herbivorous fish species could be divided into two distinct clusters, which was influenced by selective feeding behaviors on different macroalgae types. Functional analysis of gut bacteria in herbivorous fishes showed a high abundance of carbohydrate metabolism pathways. Through comparison with the carbohydrate-active enzyme (CAZy) database, eight glycoside hydrolases (GHs) and one glycosyltransferase (GT) were identified in herbivorous fishes, providing further insights into the roles of gut microbiota in macroalgae metabolism.

For species with broad distributions, lower latitudes may serve as a proxy for future warming at higher latitudes. Such space-for-time substitutions are a powerful tool for developing climate change predictions for species distributed along steep elevational gradients. To understand climate resilience of a key coastal foundation species, we examined the upper elevational limit of the native Olympia oyster (<em>Ostrea lurida</em>) along its entire range at 26 sites spanning 21° latitude, from British Columbia to Baja California. Counter to our expectations, high air temperatures did not affect variation in the upper limit of Olympia oysters. Indeed, Olympia oysters extended high into the intertidal zone at the warmer southern sites, and shading did not influence the upper limit. Our models indicated instead that extreme low temperatures set the upper limit for Olympia oysters at higher latitudes. In contrast, neither the Pacific oyster (<em>Magallana gigas</em>), a co-occurring global invader, nor barnacles exhibited clear latitudinal patterns. These findings suggest that Olympia oysters and restoration projects aimed at supporting their recovery will be resilient to increased temperatures projected by climate change models. Our results also illustrate the importance of testing the assumption that species on steep elevational gradients are living close to their upper thermal limits and will be negatively impacted by warming; for this foundation species, the assumption was false. Latitudinal studies enhance understanding of species response to climate stressors and are key to the design of climate-resilient conservation strategies.</div></div>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"208 ","pages":"Article 107149"},"PeriodicalIF":3.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
