This species faces endangerment due to its extremely narrow distribution range, combined with progressively increasing human activities recently. However, a conservation genomic assessment of P. guinanensis remains uninvestigated, thus resulting in a limited understanding of the genetic diversity of this species. Here, we assembled a high-quality reference genome for P. guinanensis using HiFi sequencing technology and conducted a comprehensive assessment of its population genetic diversity by integrating data from 191 individuals across 14 populations. The updated genome size was 1.84 Gb with a scaffold N50 of 133.2 Mb, and 21 884 coding genes were annotated. The lower genetic diversity (meanπ = 1.0253 × 10-3, meanheterozygosity = 8.8150 × 10-4), higher inbreeding levels (meanF ROH = 0.0778), and an elevated mutation load (meanMissense = 0.5660, meanLOF = 0.5689) were detected in P. guinanensis. Based on the demographic simulation, this species has experienced a significant decrease in effective population size. Our results indicated that P. guinanensis is undergoing severe genetic erosion, which may compromise its adaptive potential and increase its extinction risk. We therefore propose prioritizing genetically diverse populations as a source for captive breeding and long-term field monitoring to ensure the viability of P. guinanensis. Our study enriches the understanding of the Guinan toad-headed lizard's genetic diversity, providing useful genomic resources for conservation strategies on this species.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149038525","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}

Vocal individuality may arise incidentally from morphological variation or be shaped by social environments in which reliable recognition reduces interaction costs. Here, we investigated these non-exclusive alternatives in the Emerald-spotted Wood Dove (Turtur chalcospilos), a territorial, non-learning bird inhabiting African savanna woodlands. We quantified vocal individuality across multiple song units and tested whether acoustic variation covaried with male morphology (body size and bill dimensions) and spatial factors, including geographic distance and number of neighbors, reflecting the intensity of territorial interactions. If social pressures enhance recognition efficiency, we predicted greater acoustic dissimilarity among close neighbors and in denser neighborhoods, together with greater within-individual vocal consistency. Although songs were highly individually distinctive, morphological traits explained only a small portion of the acoustic variation, indicating that individual signatures cannot be reduced to simple biomechanical constraints. Contrary to our prediction, acoustic dissimilarity increased with geographic distance, and nearby males were more acoustically similar. Spatial effects on individual vocal consistency were weaker, although males with closer neighbors tended to show lower within-individual variation. Local male density showed no consistent effect on either pattern. These results suggest that vocal individuality in this non-learning species is more associated with spatial relationships among territorial males than with morphometric traits or competitor density. By disentangling morphometric and spatial influences, this study refines our understanding of how individual identity signals can emerge and persist in territorial systems without vocal learning or complex social structure.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149038447","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}

Central Argentina (Sierras de Córdoba and adjacent lowlands) represents a major zone of biotic convergence, yet its role in shaping diversification patterns within Ctenomys has received limited attention. Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two independent lineages (C. heniacamiare and C. osvaldoreigi) in the study area. Beyond confirming the presence of previously recognized species, our results reveal undocumented diversity. Based mainly on mitochondrial data, we identify two divergent lineages that may correspond to candidate species: one related to C. heniacamiare inhabiting the eastern slopes of the Sierras de Córdoba, and another belonging to the tucumanus group in the western lowlands. Newly documented localities further extend the known ranges of several species. Notably, the co-occurrence of haplotypes assigned to different species/lineages belonging to the mendocinus group points to complex evolutionary dynamics, potentially involving incomplete lineage sorting, ongoing hybridization, or historical introgression. Taken together, our findings highlight the Sierras de Córdoba and surrounding lowlands as a focal region for understanding diversification in Ctenomys. This study illustrates how integrative analyses of molecular and morphological data can uncover hidden diversity in rapidly evolving mammalian lineages and cautions against taxonomic inferences based on single data sources.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149024727","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}

Although captive breeding and genetic rescue are the main alternative in conservation, their genomic impacts are largely unknown, and the unintended effects of these approaches may intensify the depression by introducing new deleterious mutations. Based on whole-genome sequencing data from 247 critically endangered Chinese alligators, we constructed a high-resolution genetic variation map and identified three distinct genetic populations, clarifying their demographic history and further supporting the independent origin of the American population. Comparisons between captive and semi-wild populations revealed that captive management outperforms semi-wild management in reducing inbreeding and increasing genetic diversity, while simultaneously elevating the accumulation of deleterious mutations, which may result from relaxed purifying selection. Although the inbreeding coefficient in this species is notably higher than in other endangered species, purging has likely played a significant role in reducing the amount of recessive deleterious mutations. Forward-in-time simulations indicated that mixing populations can mitigate the risk of demographic decline, yet current populations still remain vulnerable to future environmental changes. These findings provide valuable genomic evidence to guide balanced and effective conservation strategies for the Chinese alligator.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149016713","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}

However, few studies test if fragmented habitats (e.g., forest edges) support predators through bottom-up effects. Here, we tested the effects of habitat fragmentation on multi-trophic interactions involving flowering plants, pollinators, and a common predatory spider (Atypus heterothecus). We found that spider biomass was higher at the edges of large islands than in their interiors, with no significant effect of island area or isolation. Diet analysis revealed that pollinators accounted for 70% of the spider's prey. Furthermore, prey composition differed significantly between edges and interiors, with edge habitats supporting higher prey richness, as well as greater richness and abundance of flowering plants and pollinators. The higher spider biomass was primarily driven by bottom-up effects, while top-down effects were also present but not strong enough to suppress prey biomass. Our findings suggest that conservation strategies in fragmented landscapes could improve the ecological quality of existing edge habitats, while this should be balanced against the need to protect intact interior habitats for sensitive species. By emphasizing resource-mediated trophic interactions, this study provides new insights into how ecological functions may be maintained in fragmented landscapes.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149016653","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}

These chemical cues may convey information related to identity, reproductive status, and mate quality. This study investigates the diversity of volatile compounds in the feathers of scarlet macaws (Ara macao) and examines whether their chemical composition varies according to sex, age, and pair-bond status, as well as whether plumage odor is associated with immune function. Five feathers were collected from the dorsal nape of 18 captive individuals (9 males and 9 females) at Loro Parque Fundación (Tenerife). Volatile compounds were extracted using solid-phase microextraction (SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS). Bactericidal plasma activity was assessed via flow cytometry as an indicator of innate immune function. We obtained a significantly higher number and diversity of volatile compounds in males than in females, including greater relative proportions of aldehydes and carboxylic acids and their esters. Meanwhile, partnered individuals showed higher proportions of alkenes and aromatic compounds compared to unpartnered birds. These patterns suggest that plumage volatiles are associated with sex and pair status and may contribute to reproductive communication, potentially facilitating sex recognition and social interactions. No significant relationships were detected between volatile profiles and bactericidal activity or age. Overall, this study expands current knowledge of avian chemical communication in an understudied taxon and highlights the potential relevance of olfactory cues for understanding macaw social biology and welfare.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149016677","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}

Using metagenomic sequencing of wild golden snub-nosed monkeys (Rhinopithecus roxellana), we investigated how social status (one-male unit [OMU] leaders vs. all-male unit [AMU] individuals) and seasonal variation (winter-spring [WS] and summer-autumn [SA]) shape gut microbial structure and function. We found that seasonal shifts drive primary microbial restructuring, but social status exerts a strong influence, particularly during the SA mating season. OMU leaders maintained stable microbial communities enriched in energy conservation and cellular maintenance pathways including methane metabolism and peptidoglycan biosynthesis. In contrast, AMU individuals exhibited highly plastic microbiomes potentially suited for competition, with enhanced functions in environmental sensing (e.g., flagellar assembly and two-component systems) and nitrogen metabolism. AMU gut microbiomes also showed reduced diversity in SA, indicating specialization for competitive readiness. These results demonstrate that the gut microbiome is functionally compartmentalized by social status, providing distinct metabolic toolkits that align with divergent behavioral strategies-investment in unit fitness for OMU leaders versus risk-taking for AMU individuals.

The results showed widespread pollution in the sampled bullfrog aquaculture waters, characterized by high nitrogen and phosphorus levels (total nitrogen: 4.1-7.6 mg/L; total phosphorus: 0.63-5.82 mg/L) and contamination by heavy metals such as copper and zinc. A total of 106 ARG subtypes were detected, dominated by tetracycline (1.71%) and sulfonamide (0.44%) resistance genes. Among the sampled farms, the Sichuan site exhibited the highest overall ARG abundance (10.77%). Eight high-risk ARGs, such as ermB, floR, and qnrA, were identified and were significantly associated with heavy metals, opportunistic pathogens such as Escherichia and Bacteroides, and mobile genetic elements (MGEs). The intestinal microbiota was dominated by Proteobacteria (35.27%) and Firmicutes (27.32%), while reduced microbial diversity was observed in samples from certain sites with relatively high ARG abundance, particularly the sampled farm in Sichuan. ARG community assembly was primarily consistent with stochastic processes, whereas variation in ARG profiles was significantly associated with MGEs, geographic location, heavy metals, environmental factors, and opportunistic pathogens. These results suggest a potential interplay between stochastic ecological dynamics and environmental selection in shaping ARG patterns.
