Mineralized tissues accumulate elements that play crucial roles in animal health. Although elemental content of bone, blood and teeth human some species have been characterized, data for many others are lacking, as well comparisons. Here we describe the distribution horn (Bovidae), antler (Cervidae), bone (humerus) across a number determined by handheld X-ray fluorescence (XRF) to better understand differences potential biological relevance. A difference profiles between horns antlers was...
The ability to estimate age and determine the growth status of free-ranging dugongs ( Dugong dugon ) is vital providing insight into basic biology this endangered species. Currently, estimation in dugong carcasses relies on counting dentin layer groups (GLGs) tusks, but a disadvantage they need be intact. We explored whether measures telomere length could used as an alternative approach given that other species, are inversely related. In study, relative (rTL) was measured by qPCR skin...

Data analyzed by univariate analysis, followed discriminant analysis multivariate linear regression. Here we show, 100% 98.5% accuracy rates for sexing using large skull,...
Cetaceans inhabit oceans throughout the world. Four specific odontocetes, namely Cuvier's beaked whale (Ziphius cavirostris), Indo Pacific finless porpoise (Neophocaena phocaenoides), pygmy sperm (Kogia breviceps), and dwarf sima), have occasionally been found stranded along Thailand's coastal waters (the Andaman Sea Gulf of Thailand). Although shared haplotypes each species for many locations found, some revealed genetic structure through haplotype networks, cetaceans in Thai never...
Abstract The elemental composition was investigated and applied for identifying the sex habitat of dugongs, in addition to distinguishing dugong tusks teeth from other animal wildlife materials such as Asian elephant ( Elephas maximus ) tiger Panthera tigris canine teeth. A total 43 tusks, 60 teeth, 40 dolphin 1 whale tooth, 20 were included study. Elemental analyses conducted using a handheld X-ray fluorescence analyzer (HH-XRF). There no significant difference male female whereas overall...
Although the existence of two cetacean species in and around Thai Seas from within subfamily Globicephalinae, Risso’s dolphin Grampus griseus G. Cuvier, 1812, false killer whale Pseudorca crassidens Owen, 1846, has been known for decades, current knowledge on abundance, genetic diversity, conservation status these marine mammals is limited as are rare oceanic Thailand’s territorial waters. Frozen skin tissue samples taken six cetaceans (four dolphins: whales) stranded along coastlines were...
The leatherback sea turtle (Dermochelys coriacea) is the largest and one of most migratory species, inhabiting oceans throughout world. There has been a steady decline in populations over past several decades due to human activities. They are considered endangered Thailand global, so conservation strategies needed study protect including determining their genetic diversity. A total 8 microsatellite loci 658 bp amplicon mitochondrial DNA (mtDNA) were used assess data from 149 dead hatchlings...
Currently, species identification of stranded marine mammals mostly relies on morphological features, which has inherent challenges. The use genetic information for mammal remains limited, therefore, new approaches that can contribute to a better monitoring are needed. In context, the ISSR-HRM method we have proposed offers approach identification. Consequently, need be developed identify individuals at level. Eight primers ISSR markers were chosen HRM analysis resulting in ranges accuracy...
Marine mammals vary greatly in size and lifespan across species. This study determined whether measures of adult body weight, length relative telomere were related to lifespan. Skin tissue samples ( n = 338) obtained from 23 marine mammal species, including four Mysticeti, 19 Odontoceti one dugong the DNA extracted measure using real-time PCR. Life span, each species retrieved existing databases. The phylogenetic signal analysis revealed that might be a significant factor for shaping...
Two stranded Lepidochelys-like sea turtles were rescued from the Thai Andaman Sea coastline by veterinarians of Phuket Marine Biological Center (PMBC), one in May 2019 and another July 2021. They first identified as olive ridley (Lepidochelys olivacea), external appearance both was closer to that species than other four found Sea. In fact, when carefully examined, an unusual pattern lateral scutes on each turtle observed, specifically symmetric 5/5 asymmetric 5/6, which are considered rare...
Abstract The Irrawaddy dolphin ( Orcaella brevirostris ) is an endangered cetacean that ranges throughout much of Southeast Asia and lives in coastal, estuarine, riverine habitats including three river systems: Ayeyarwady, Mekong, Mahakam. Many populations face risks from human interference, but overall rangewide diversity connectivity not well‐understood. Here we sequenced 77 complete mitogenomes across the range all obligate populations; eighteen these were historical museum specimens....
Cetaceans and sirenians are endangered marine mammals that threatened by stranding mortality. In Thailand's Andaman Sea, limited data exist on the causes patterns of these events. This retrospective study investigated characterization underlying cetacean sirenian mortality events in Sea from 2018 to 2023 using information Department Marine Coastal Resources, Thailand. Data 363 stranded mammals, including both live dead strandings, species types, carcass condition, necropsy findings...
Abstract The dugong ( Dugong dugon Müller) is recognized as an endangered marine mammal. There limited available anatomical data on the dugong’s skeletal system, while what has not been well established due to number of archived samples and access them. Importantly, there are certain key questions that should be answered when examining bones and/or remains animals such as; kind bone it?; species does it belong to?; sex was animal?; how old animal? or big it?, etc. In this study, we have...
