However, their genetic diversity and population connectivity remain poorly understood due to limited sampling. To fill these knowledge gaps, we compared the population genetics of two vent- and seep-dwelling alvinocaridid species with overlapped geographic ranges between the South China Sea and the Manus Basin. Alvinocaris longirostris has a wider distribution, ranging from 35°N to 3°S and at depths of 930 to 1736 m, while Alvinocaris kexueae is more restricted, found between 16°N and 3°S at depths of 1300 to 1910 m. Our analysis, based on the mitochondrial cytochrome c oxidase subunit 1 gene, revealed that A. longirostris had lower genetic diversity and minimal genetic differentiation across eight disjoint vent and seep populations. In contrast, the narrower-distributed A. kexueae exhibited higher genetic diversity and significant genetic differentiation, with stronger gene flow observed from its Haima seep population to the Manus Basin vent population. In addition, both species appear to have experienced population expansion in their recent evolutionary history. These results suggest that A. longirostris and A. kexueae may possess distinct life-history traits that contribute to their differing distribution ranges in the Western Pacific.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143052213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Baseline comparisons showed no significant difference in effectiveness between tail coiling and tail lashing without environmental constraints, though side-on tail coiling was consistently more effective than front-on displays. When noise proximity was introduced, tail lashing was more effective when the noise source was nearby, but this advantage diminished with distance. Conversely, tail coiling maintained consistent effectiveness across varying noise proximities, especially from a side-on view. In complex habitats with diverse plant species and varying wind conditions, tail lashing proved more effective, particularly from a front-on perspective, while tail coiling excelled from a side-on view. From a predator's perspective, tail lashing was slightly more effective under low wind conditions at close distances, though its visibility decreased with higher wind speeds.

For many web-building spiders in the Nephilidae family, reproductive success increases with body size, which in turn, is related to diet. The diet of female spiders may overlap with males who share her web, but diet patterns could depend on size if certain males have better access to prey ensnared in the web. Therefore, we tested the hypothesis that Joro spider (Trichonephila clavata) dietary patterns are sex-specific and related to body size and condition. We combined morphometric size analysis with molecular gut content analysis via DNA metabarcoding and high-throughput sequencing to characterize male and female Joro spider diets from 60 webs at 25 locations. Female Joro spiders were larger than males and their diets were more diverse. While male Joro spiders consumed the same prey taxa as females, more than 50 additional taxa were detected in female diets, which led to significant dissimilarity in prey composition between sexes. As male body size increased, diet diversity and body condition decreased, suggesting a potential trade-off between time spent foraging versus active defense of their position on the web. Female and male spiders captured from the same web shared prey taxa. However, the proportion of prey overlap was not related to male size. Combined, Joro spiders show sex-specific dietary patterns, and males appear to have less access to the diverse food captured in female webs.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypoxic stress, characterized by a reduced level of dissolved oxygen, is an escalating threat to marine ecosystems, with potentially devastating effects on the viability of endangered species such as the tri-spine horseshoe crab Tachypleus tridentatus. Even though this species is remarkably resilient to low oxygen levels, persistent hypoxia can negatively impact its population's survivability. The objective of this research was to examine the impact of short-term hypoxia on the behavior, gut microbiota, and metabolomics of juvenile T. tridentatus. First instar juvenile horseshoe crabs were subjected to hypoxic stress (2 mg O<sub>2</sub>/L) for 14 days and then recovered for 7 days in an environment with normal dissolved oxygen. The findings demonstrated that short-term hypoxia reduced the rates of swimming and burrowing of horseshoe crabs, and induced the change of tissue metabolites and intestinal flora malfunction. Additionally, in the hypoxia groups on day 14, 86 distinct metabolites showed a trend of downregulation, while 29 metabolites showed an upregulation trend. Arginine biosynthesis; histidine metabolism; vitamin B6 metabolism; aminoacyl-tRNA biosynthesis; and alanine, aspartate, and glutamate metabolism were the top five metabolic KEGG pathways (p < 0.05) enriched with 8 metabolites. In conclusion, our results provided new insights related to the behaviors, microbiota, and metabolites involved in juvenile T. tridentatus exposed to short-term hypoxic conditions and confirmed that hypoxia impairs their behavioral and physiological status.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142983457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
