Examining unhatched eggs during post-emergence nest excavation could lead to eggs being mistakenly identified as unfertilized eggs due to the difficulty in differentiating between unfertilized eggs and early embryonic mortality. It is essential to determine the egg fertility of hawksbill turtles in Melaka before concluding that hatching failure is due to infertility. Egg fertility was determined using the white spot method conducted at the beginning of egg incubation on 50 clutches. Mean egg fertility was 85.9%, but the mean hatching success was significantly lower at 57.6% (mean emergence success was 56.8%). The results showed that egg fertility did not reflect hatching success and infertility was unlikely the cause of hatching failure. The huge number of undeveloped eggs may have been due to early embryonic death that went undetected at the end of incubation.</p></div>","PeriodicalId":37957,"journal":{"name":"Journal of Asia-Pacific Biodiversity","volume":"17 3","pages":"Pages 451-456"},"PeriodicalIF":0.6,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2287884X24000311/pdfft?md5=8ca7df691674fd26dbed6938c98a7caa&pid=1-s2.0-S2287884X24000311-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140402848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To analyze the subspecies boundaries based on potential song and morphometric traits, we recorded, measured, and analyzed song characters and morphometry of the three bulbuls along the Thai-Malay Peninsula. The geographic variation of songs and morphometry differs significantly for specific traits; however, we could not find any trait discontinuities that would be in accordance with previously documented phylogeographic divides. Instead trait variation was mostly clinal and followed a North-South gradient in line with Bergmann’s rule.
