Species distributions, diversity and endemism were analysed using cluster analysis of a Simpson's beta (βsim) dissimilarity matrix to delineate provinces, with provincial assignments interpreted in light of the PAIC framework and prior biogeographic evidence. Inventory completeness per province was quantified using coverage-based rarefaction. Generalised Dissimilarity Modelling (GDM) was used to quantify the relative contributions of geographic, environmental and historical predictors to compositional turnover, with predictor importance and statistical significance assessed by matrix permutation. Indicator species analysis (IndVal) was applied to both the full dataset and the obligate primary-freshwater (PF) subset, and dendrogram congruence between the two analyses was tested with a Mantel test and cophenetic correlation.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Cluster analysis resolved five freshwater fish biogeographic provinces: Northern Luzon, Central/Southern Luzon, Greater Visayas, Mindanao and Palawan–Mindoro. Geographic distance was the strongest correlate of compositional turnover, while PAIC grouping and contemporary climate variables contributed comparatively little once geographic distance was accounted for. Two patterns stood out. First, the Visayan islands of Leyte and Samar clustered with the rest of the Greater Visayas rather than with Greater Mindanao, despite their conventional PAIC assignment to the latter, a pattern consistent with contemporary marine straits exerting biogeographic influence beyond what Pleistocene land-bridge predicts. Second, Palawan–Mindoro stood out as a Sundaic outlier within the Philippine archipelago, anchored by obligate primary-freshwater Cyprinidae of Bornean affinity. By contrast, Greater Visayas lacked any significant obligate-freshwater indicator and was characterised instead by an estuarine–freshwater interface assemblage, supporti","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Suitable habitats contracted during the Last Glacial Maximum and under future climate scenarios, with species such as &lt;i&gt;A. deng&lt;/i&gt; and &lt;i&gt;A. tuberodepressus&lt;/i&gt; projected to lose substantial habitat. Vulnerability assessments further indicated that &lt;i&gt;A. chaochin&lt;/i&gt;, &lt;i&gt;A. deng&lt;/i&gt;, &lt;i&gt;A. tuberodepressus&lt;/i&gt;, and &lt;i&gt;A. xinduqiao&lt;/i&gt; were particularly vulnerable to climate change.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The diversification of &lt;i&gt;Amolops&lt;/i&gt; appears to have been strongly influenced by Miocene geological and climatic changes, which shaped both the distribution and evolutionary history of the genus. Climatic fluctuations have markedly constrained suitable habitats, with species sensitivity proving more critical than habitat exposure in determining vulnerability to climate change. Despite these challenges, the Hengduan Mountains contain multiple regions likely to have served as long-term climatic refugia, supporting the persistence of &lt;i&gt;Amolops&lt;/i&gt; species. Current protected areas encompass only a small fraction of these refugial zones (&lt; 7%), highlighting substantial gaps in conservation coverage and underscoring the need to prioritize t","PeriodicalId":15299,"journal":{"name":"Journal of Biogeography","volume":"53 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Anomalies, such as a bifurcation or a trifurcation of a regenerated gecko tail, can change locomotion, social signalling, and predator evasion, with potential effects on survival and reproductive success. Even though rare, these abnormalities raise important questions about their potential associations with environmental conditions and global distribution. We investigate the prevalence and potential correlates of abnormally regenerated tails in geckos.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Global.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Time Period&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;1964–2023.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Major Taxa Studied&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Lizards.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We analysed spatio-temporal patterns of anomaly prevalence based on 136,069 iNaturalist observations of 122 gecko genera. We overlaid the location of each observation with climate variables from WorldClim and PM2.5 air pollution data from a global monitoring database and explored whether ecological traits, i.e., activity period (diurnal, nocturnal, or cathemeral) and habitat use (fossorial, arboreal, terrestrial, or saxicolous) change the likelihood of abnormal tail regeneration.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We identified 89 cases of abnormal tail regrowth in 21 genera. While the number of all observations increased over time, particularly since 2018, the annual rate of abnormalities peaked in 2006. No spatial autocorrelation was detected, and ecological traits, such as activity period and habitat use, did not affect abnormality rates. Fossorial genera exhibited no caudal abnormalities. Solar radiation showed a marginally positive effect (&lt;i&gt;β&lt;/i&gt; = −0.23, &lt;i&gt;p&lt;/i&gt; = 0.063) on the likelihood of multiple tails.
