This study aimed to assess changes in the occupancy of Capped Langurs across 40 rainforest fragments between February 2019 and January 2020 and to identify the ecological and landscape-level factors influencing their persistence. Using generalized linear models, we examine the attributes at both patch and landscape levels that influence the occurrence of Capped Langurs in these fragments. Of the 40 surveyed sites, we found Capped Langurs only in 11 fragments. We discovered that the diversity of food tree species in these fragments had the most significant impact, explaining the presence of Capped Langur troops. Our findings highlight the urgency of targeted habitat restoration, emphasizing the need to enhance and protect food and roost tree diversity in these degraded fragments. This will ensure a rich composition of native food and roosting trees to support Capped Langurs in these rainforest fragments.</div></div>","PeriodicalId":37957,"journal":{"name":"Journal of Asia-Pacific Biodiversity","volume":"18 4","pages":"Pages 867-874"},"PeriodicalIF":0.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145718963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, inconsistencies between morphological characteristics and molecular data have often been observed, and previous studies have been insufficient in accurately establishing the phylogenetic placement of <em>Ceratophyllum</em>. Therefore, this study sequenced and assembled two <em>Ceratophyllum</em> (156,104–156,252 bp) by Illumina Truseq Nano sequencing.
