The blood quality was analysed by measuring Cu content. The results showed that, on Days 0, 30, 60 and 90, the Cu content in the blood of male juvenile T. tridentatus was 37.15, 22.62, 10.15 and 16.63 mg/L, respectively, with Days 30, 60 and 90 being 39.10%, 72.69% and 55.23% lower than Day 0. The Cu content in the blood of female T. tridentatus on Days 0, 30, 60 and 90 was 39.89, 20.27, 7.33 and 7.53 mg/L, respectively, with decreases of 45.44%, 80.26% and 81.11% on Days 30, 60 and 90 compared with Day 0. This indicated that the blood quality of male and female T. tridentatus decreased under captive breeding conditions. To measure metabolites, three male and three female T. tridentatus were selected and cultured under captive breeding conditions, and blood samples were collected on Days 0 and 30 and analysed using nontargeted metabolomics. Thirteen differentially expressed metabolites were identified, among which six significantly increased and seven significantly decreased. Among metabolic pathways, the sphingolipid metabolic pathways were notably affected. Changes in significant metabolites and metabolic pathways revealed nutritional deficiencies in protein, fat and vitamins. Insufficient nutrient supply was an important reason for the decline in blood quality of T. tridentatus under captive breeding conditions. In addition, four significantly different metabolites, namely, sphingosine, heptadecasphingosine, D-erythro-imidazolyl glycerophosphate and stearic acid, were selected as future target metabolites to analyse the nutritional demand of T. tridentatus under captive breeding conditions.\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116136","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}

Some species, including the European pond turtle (Emys orbicularis), have been the subject of long-term monitoring programmes carried out within large, well-preserved wetlands and based on robust capture–mark–recapture (CMR) protocols. Yet demographic studies of small isolated populations are very scarce. In this study, a highly isolated population of E. orbicularis was intensively monitored in the Durance River Valley in southeastern France over five consecutive years (2013–2017). In total, 153 adult individuals were used to estimate demographic parameters using two different CMR Robust Design model formulations. These models estimated a relatively constant adult population size, annual survival and seniority probability over time, similar for both sexes, but a highly unbalanced sex ratio in favour of females (0.24 male per female on average). The results showed that this isolated population exhibits atypical and little-known demographic parameters in this species. The highly unbalanced sex ratio in favour of females could be the result of factors impacting sexual determinism during embryonic development. This imbalance could ultimately reduce the reproductive output and increase the risk of extinction of the population. These results highlight the need for both a better understanding of the mechanisms underlying the origin of such an imbalance, and in identifying the critical thresholds that must not be crossed to guarantee the viability of sex-biased populations.\u0000 </div>","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116132","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}

This investigation sought to generate insights into the phylogeography of these two species, which are poorly understood in their Hawaiian range. Data from the mitochondrial COI gene from six collecting sites on four of the main Hawaiian Islands suggest high connectivity among M. grandimanus populations and indicate a possible population expansion characteristic of colonization of remote islands. The data also support a clear separation of the Hawai'i M. grandimanus from populations outside Hawai'i. For M. lar, COI data from five collecting sites on three of the main Hawaiian Islands revealed only three haplotypes, which showed a phylogenetic affiliation to populations in the North Pacific region of the species' native range. In sum, these new insights on population connectivity and phylogenetic affiliations provide relevant information that can assist conservation efforts of the native species M. grandimanus in Hawai'i and suggest that M. grandimanus should be managed as an endemic species.

The emergence of genomic techniques has significantly improved our understanding of species units in the group, yet there is one species of devil ray for which uncertainty remains. Mobula rochebrunei (Vaillant, 1879), a pygmy devil ray inhabiting tropical waters of the eastern Atlantic, was recently synonymised with Mobula hypostoma (Bancroft, 1831), its western Atlantic counterpart. However, since there have been no sightings of the species in West and Central Africa for several decades, the revision was based on limited data, and further investigation was recommended. A dedicated monitoring effort in Cameroon recently led to the rare discovery of three pygmy devil rays, providing a unique opportunity to build on recent work. We use a combination of MinION sequencing and morphometric analysis to provide confirmation that pygmy devil rays on both sides of the Atlantic constitute the same species.

Studies on modern and fossil rhodoliths assume such associations to vary with water depth. Our study explores the quantitative biological composition of calcareous rhodolith matrices along a bathymetric gradient at the Arctic Svalbard archipelago. Using a methodological combination of virtual micro-CT cross-sections with a modified point counting approach, we found five different taxonomic groups: CCA, bivalves, serpulids, bryozoans and balanids. While water depth does not influence the general taxon richness as well as the abundance of bivalves, it significantly affects the proportional matrix composition of encrusting organisms by a combination of environmental factors and biological interactions. The decrease in CCA skeletal material with increasing water depth is significantly governed by impaired irradiance conditions. Regular rhodolith movement in shallow waters fosters the proportion of CCA, while decreased movement in deeper waters spurs the proportion of other encrusters. This potentially results from post-mortem fouling of dead rhodolith parts followed by a recolonization with slow-growing CCA species Boreolithothamnion glaciale. Our results highlight mechanisms controlling the biogenic composition of calcareous rhodolith matrices and underline the potential of matrices compositions for palaeogeography and palaeobathymetry. Our study contributes to an improved understanding of the composition and developmental patterns of rhodoliths. This can add to a better comprehension of the respective ecosystems on a broader scale and be beneficial for conservation purposes.","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"35 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aqc.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under climate change, these species could experience northward range shifts, expanding their range in United Kingdom (UK) coastal waters, potentially requiring the UK to take a leadership role in European seahorse conservation in the future. This review aims to synthesise current scientific research to provide an overview of how these seahorse species are likely to respond to climate change. Using the most recent Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6), predictions for future change along with the likelihood and severity of seahorse species response are combined to provide a confidence ranking in the climate change risk for these species in the UK. When considering individual factors, such as sea surface temperature, these seahorse species show some resilience, but climate change is the cumulative impact of multiple stressors, which existing research has not been able to capture.

The loss of floodplain ecosystems worldwide increased interest in restoration projects throughout the world, centred around the concept of nature-based solutions (NBS). Floodplain restoration is increasingly regarded as one of the most successful forms of NBS. However, stream restoration projects lack in-depth monitoring practices, highlighting the need for evaluations of NBS restoration success on riparian vegetation. This study analysed patterns in plant species diversity and composition following restoration of the Bosscherveld floodplain, part of the Grensmaas Project, the largest nature-based river restoration project in the Netherlands. A total of 173 species were recorded over 325 quadrats. For each plot, hydro-geomorphological factors were analysed. Habitat type and water depth were key determinants of plant species distribution. Species richness significantly declined in relation to increasing hydrological stress, and vegetation was distributed according to species-specific tolerances to disturbance. Spatial coordinates, habitat type, sediment type, water percentage and depth all significantly contributed to differences in vegetation composition. Spatial variables emerged as the most significant contributors to the explained variation. The study concludes that the Bosscherveld floodplain displays high habitat heterogeneity and a significant presence of wetland species, aligning with initial restoration objectives. These findings underline the importance of monitoring to enhance the effectiveness of river restoration projects, ensuring the continued success of NBS initiatives in floodplain ecosystems.","PeriodicalId":55493,"journal":{"name":"Aquatic Conservation-Marine and Freshwater Ecosystems","volume":"34 12","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aqc.70023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Policies that foster rhodolith bed conservation needs, explaining their wealth of valuable contributions to society, must be introduced in formal education, dialoguing with children, young people and adults.
