Zooplankton, a primary natural food source in aquaculture, plays a crucial role in maintaining ecosystem function. Thus, understanding how zooplankton communities respond to environmental changes is essential for economic and ecological outcomes. In this study, we examined three types of aquaculture ponds (crab, crayfish, and fish ponds) with over 10 years of history and analyzed 27 environmental factors potentially influencing zooplankton dynamics throughout the year. Our results showed that Rotifera was the most abundant group in all three pond types, followed by Protista, Cladocera, and Copepoda. The dominant species across different seasons and ponds were <i>Polyarthra vulgaris</i>, <i>Anuraeopsis fissa</i>, and <i>Trichocerca pusilla</i>. The alpha diversity of zooplankton was influenced by various environmental factors across different pond types, with significant effects of antibiotics observed only in the fish ponds. The temporal and spatial distributions of zooplankton communities varied significantly. Deterministic processes, driven primarily by temperature and ammonia nitrogen, were identified as the primary mechanisms influencing zooplankton community assembly in freshwater aquaculture ponds. These findings inform management practices aimed at regulating key environmental drivers and optimizing zooplankton dynamics, with implications for maintaining ecosystem stability and productivity and, ultimately, supporting sustainable aquaculture.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s42995-025-00297-7.</p>","PeriodicalId":53218,"journal":{"name":"Marine Life Science & Technology","volume":"7 3","pages":"549-564"},"PeriodicalIF":5.3,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12413362/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145016703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lipidomic techniques were used to measure changes in mitochondrial membrane, including potential mitochondrial membrane remodeling during acute thermoregulation in gerbils. Heat acclimated gerbils showed lower basal metabolic rates but no changes in adaptive non-shivering thermogenesis were detected. A significant mitochondrial membrane remodeling with increases in monounsaturated/polyunsaturated free fatty acids ratios was associated with the decrease in metabolic rate. During heat acclimation, mitochondrial cytochrome C oxidase activity was elevated in brown adipose tissue, presumably caused by the increase in membrane unsaturation.

Such ecological variations might imply potential genetic divergence and local adaptation. We resequenced 117 genomes from six coastal stocks of <i>P</i>. <i>argenteus</i> in China. Although no hierarchical genetic structure was identified, over 50% of the single-nucleotide polymorphisms (SNPs) indicated moderate to strong divergence in at least two stocks. The Mantel test identified 21 100-kb sliding windows with significant isolation by distance and environment, while a majority did not. Given the lack of genome-wide isolation by distance, the 21 windows may be under selection pressure from the latitudinal-environmental variations. Among the 21 windows, certain genes were linked to circadian clock regulation and thermal stress response, suggesting sea surface temperature and sunshine duration as selective forces. A total of 17 genes regulated neuron activity; variations near these genes might subsequently shape the different spawning and migratory behaviors among the stocks. Additionally, 1204 SNPs were mapped to non-coding regions; 14 transcriptional and translational factors were identified in the 21 windows.

This biodiversity has spurred extensive research into its evolutionary and biogeographic origins. Two prominent theoretical frameworks dominate explanations for the IAA's biodiversity: the \"centers-of hypotheses\" and the \"hopping hotspot hypothesis\". The \"centers-of hypotheses\" posits that specific regions serve as key sources of IAA biodiversity, either through the accumulation and overlap of species from external areas or via elevated rates of local speciation. In contrast, the \"hopping hotspot hypothesis\" asserts that biodiversity hotspots are dynamic, shifting across geological timescales in response to tectonic and environmental changes. This review synthesizes these contrasting perspectives into an integrated framework, the \"Dynamic Centers Hypothesis,\" which proposes that as biodiversity hotspots migrate over time, the IAA's role in generating and sustaining biodiversity has evolved, with varying contributions from different sources dominating distinct historical phases. By synthesizing the evidence for both hypotheses and incorporating recent findings, including fossil and phylogeography data, we propose the \"Dynamic Centers Hypothesis\" as a comprehensive and unifying explanation for the IAA's biodiversity. The review further explores biogeographic delineation, aligning tropical marine realms with the IAA's evolutionary trajectory, from its Tethyan roots to its modern Indo-West Pacific dominance. Looking forward, advances in DNA barcoding and genomics are uncovering vast cryptic diversity, revolutionizing our comprehension of IAA phylogeographic history.

Given the direct influence of extracellular enzymes on nutrient availability, understanding their diversity and dynamics is crucial in comprehending microbial interactions and organic matter cycling in aquatic ecosystems. In this study, metagenomics was employed to investigate the functional diversity and dynamics of extracellular enzymes and transporters in coastal waters over a 22-day period. The metagenome-derived gene pool of organic matter-degrading secretory enzymes and transporters was primarily contributed by three major bacterial classes. Bacteroidota were the primary contributors to the gene pool of secretory carbohydrate-active enzymes (CAZymes), whereas Gammaproteobacteria contribute more to secretory peptidases and TonB-dependent transporters (TBDTs), and Alphaproteobacteria to ATP-binding cassette (ABC) transporters. The distinct substrate targets of the enzymes and transporters combined with the unique dynamics of these taxa across depth layers suggest that organic matter degradation and uptake machinery played a role in ecological niche partitioning. At the community level, the abundance of TBDT genes was more positively correlated with extracellular enzymes than ABC transporters. To further explore taxon-specific differences, we reconstructed 163 bacterial and archaeal metagenome-assembled genomes (MAGs). Correlation patterns at the MAG level varied across taxa: Bacteroidota MAGs exhibited significant positive correlations between TBDTs and extracellular enzymes, whereas Gammaproteobacteria and Alphaproteobacteria MAGs showed weak or no significant correlations. These results suggest the diversity of ecological strategies among marine heterotrophic bacteria and highlight a potential coregulation or functional linkage between extracellular enzymes and TBDTs in the metabolism of marine heterotrophic prokaryotes.

However, the mechanisms underlying the formation and maintenance of the anammox bacterial community remain unclear. This study analyzed the anammox bacterial diversity, community structure, and interspecific relationships in three estuaries along the Chinese coastline -the Changjiang Estuary (CJE), the Oujiang Estuary (OJE), and the Jiulong River Estuary (JLE) - as well as the South China Sea (SCS) to elucidate their community assembly mechanisms. The results indicated that the anammox bacterial community exhibited the highest ammonium concentration as well as the Shannon's diversity index reflecting both species richness and evenness in the JLE. The lowest Shannon index was observed in the SCS. However, the anammox bacterial species richness was greatest in the CJE. <i>Candidatus</i> Scalindua was the predominant anammox bacteria identified in the coastal sediments, especially in the SCS sediments. <i>Candidatus</i> Brocadia and <i>Candidatus</i> Kuenenia were more abundant in the estuarine sediments, particularly in JLE, than in the SCS. Phylogenetic analysis revealed distinct differentiation among <i>Candidatus</i> Scalindua, <i>Candidatus</i> Brocadia, and <i>Candidatus</i> Kuenenia, with the former exhibiting a greater level of diversity. There was significant spatial heterogeneity in the anammox bacteria across the four regions, characterized by distinct distribution patterns for rare species. Low-abundance (rare) bacteria thrived in their native habitats, whereas abundant taxa displayed greater dispersal capabilities. An analysis of the community assembly mechanism suggested that ecological drift predominantly shaped the overall anammox bacterial community in the coastal sediments.

In the present study, we measured substrate temperature, air temperature, wind speed, light intensity, and body temperature to evaluate the relative importance of drivers that affect body temperature in different microhabitats, and determined the metabolomic responses of intertidal snails <i>Littorina brevicula</i> and limpets <i>Cellana toreuma</i> from different microhabitats (snail: exposed vs. shaded rock; limpet, rock vs. tidal pool) during extreme low-temperature event in winter. Results showed that microhabitat type, substrate temperature, air temperature, wind speed, and light intensity contribute notably to the body temperatures. During extreme low-temperature events, mollusks collected from different microhabitats exhibited microhabitat-specific metabolomic responses that are associated with cellular stress response, energy metabolism, immune response, nucleotide metabolism, and osmoregulation. These metabolic pathways were highly induced in the more exposed areas (exposed rock for snails and rocky environment for limpets). Notably, in different microhabitats, the metabolites enriched from these pathways showed significant correlations with microclimate environmental variables (i.e., substrate temperature, wind speed, and body temperature).

It is crucial to further enhance our understanding of the ecological and biological aspect of the queen snapper to effectively manage and conserve this species as fishing pressure has been extended to deep water species in the US Caribbean.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s42995-025-00289-7.</p>","PeriodicalId":53218,"journal":{"name":"Marine Life Science & Technology","volume":"7 3","pages":"594-605"},"PeriodicalIF":5.3,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12413376/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145014507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
