The Qinghai-Tibet Plateau shows decreasing nutrient availability with rising elevation, and its endemic Schizopygopsis younghusbandi is an ideal model for nutrient scarcity adaptation. We mimicked nutrient deficiency via in vitro low-serum and in vivo starvation assays, identifying that inhibin βB acts centrally: its upregulation activates the SMAD pathway, inducing G1 phase arrest, attenuated proliferation, and reduced energy consumption. Nutrient deprivation also upregulates pdgf-c to induce a fibrotic phenotype in muscle satellite cells. In vivo assays verified inhibin βB elevation, reversible upon refeeding. We established a S. younghusbandi muscle satellite cell culture system, elucidating inhibin βB-mediated adaptive mechanisms. Comparative sequence analysis across eight Cyprinid species revealed high conservation (>90%) of inhibin βB, suggesting evolutionary preservation.

Trachemys scripta (Schoepff, 1792) is one of the world's most widespread invasive turtle species. Although some previous studies have focused on T. scripta reproduction, both in native and in non-native ranges, only one study has been carried out in Portugal, which reported clutch sizes. The aim of this study is to determine which morphological traits affect reproductive traits of T. scripta in Algarve, Portugal. We used shell measurements and body condition to explain reproductive organ morphometrics, fecundity, and clutch size, using both generalized linear models and a Bayesian framework. Overall, in females, reproductive variables were only explained by plastron length, except for the number of stage IV follicles, which was also explained by body condition. In males, only the gonadosomatic index was explained by plastron length and plastron width as well as body condition index. Female T. scripta in Portugal showed a strong size-dependent reproductive relationship, with plastron length positively influencing all major reproductive traits. Our Bayesian analysis indicated that females reach sexual maturity at 15-18 cm. In males, morphology was poorly related to reproductive traits variation, although lower body condition was associated with larger gonads. These results show that environmental conditions in southern Portugal support successful reproduction, reinforcing the species' potential for long-term establishment. These findings highlight the importance of large reproductive females in driving population growth and provide essential demographic parameters for modeling and managing invasive T. scripta populations in Europe.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149038397","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}

A core challenge remains: how to translate evolutionary genomic discoveries into actionable conservation strategies, rather than treating genomic metrics as end-point indicators in isolation. Gibbons, an iconic primate lineage defined by rapid adaptive radiation, extreme genome structural remodeling, derived brachiation locomotion, and global conservation priority status, offer an exemplary system to explore the integration of evolutionary genomics and conservation biology. Multi-temporal genomic data, spanning extant populations, subfossil remains, and historical museum specimens, now offer unprecedented resolution to trace extinct lineages, establish pre-anthropogenic genetic diversity baselines, and dissect the genetic architecture of adaptive traits. Nonetheless, there is a growing risk of overinterpreting genomic indicators in conservation planning, without accounting for ecological context, population demography, habitat dynamics, and local management realities, creating a persistent gap between genomic discovery and on-the-ground conservation impact. Against this backdrop, this review synthesizes gibbon genomic research to propose a framework from evolutionary reconstruction and multidimensional vulnerability assessment to conservation intervention and long-term dynamic monitoring. We clarify the supporting role of genomic evidence in conservation decision-making, and delineate a practicable pathway for integrating genomics with field ecology and conservation management. Beyond gibbons, this paradigm provides a generalizable reference for conservation genomic practice across endangered primates and vertebrates more broadly.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149038504","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}

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.

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}

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.

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.

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.
