Bats are natural reservoirs for several highly pathogenic and novel viruses including coronaviruses (CoVs) (mainly Alphacoronavirus Betacoronavirus). Lyle's flying fox (Pteropus lylei)'s roosts foraging sites usually in the proximity to humans animals. Knowledge about age-specific pattern of CoV infection P. lylei, prevalence, viral shedding at may have an impact on infection-age-structure model control outbreak. lylei bats were captured monthly during January–December 2012 detection three...
The North African catfish ( Clarias gariepinus ) is a significant species in aquaculture, which crucial for ensuring food and nutrition security. Their high adaptability to diverse environments has led an increase the number of farms that are available their production. However, long-term closed breeding adversely affects reproductive performance, leading decrease production efficiency. This possibly caused by inbreeding depression. To investigate root cause this issue, genetic diversity...
Hybrid sterility, a hallmark of postzygotic isolation, arises from parental genome divergence disrupting meiosis. While chromosomal incompatibility is often implicated, the underlying mechanisms remain unclear. This study investigated meiotic behavior and genome-wide in bighead catfish (C. macrocephalus), North African gariepinus), their sterile male hybrids (important aquaculture). Repetitive DNA analysis using bioinformatics cytogenetics revealed significant satellite (satDNA) families...
Abstract Climate change has driven global temperature increases, resulting in severe heat waves, altered precipitation patterns, and extreme weather events. In April 2024, a massive die‐off of hybrid catfish larvae fry occurred Thai aquaculture farms, coinciding with elevated temperatures air (37–41°C) freshwater (30–32°C). This study aimed to investigate the correlation between abnormal embryonic development catfish. Controlled mating male North African ( Clarias gariepinus ) female bighead...
Ecosystems are being disrupted by climate change and habitat fragmentation, which affect species survival through altered mating, feeding, migration patterns. Mae Hong Son Province, Thailand, harbors a unique hydrological network that supports rich freshwater fish biodiversity. Blue mahseer ( Neolissochilus stracheyi ), is restricted to headwater streams in Son, particularly sensitive disturbances has experienced population decline. Despite their vulnerability information on the genetic...

Abstract. Khajitmathee N, Kaewtongkum Chaiyes A, Suksavate W, Duengkae P, Sribandit Phochayavanich R, Chuaynkern C, Y. 2025. Current distribution and habitat suitability for the present future scenarios of Cyrtodactylus angularis in Thailand. Biodiversitas 26: 1039-1050. The genus Cyrtodactylus, with approximately 381 species, is among most speciose family Gekkonidae. angularis, an endemic species Thailand, was assessed using Ecological Niche Modeling (ENM). This study evaluates species'...
Knowledge of the genetic characteristics, origin, and local adaptation chickens is essential to identify traits required for chicken breeding programs. Chee Fah Luang are black-boned breeds reared in Chiang Rai, Thailand. Chickens an important part economy socio-culture; however, diversity, origins these two have been poorly studied. Here, we investigated gene pool, origin using mitochondrial DNA D-loop (mtDNA D-loop) sequencing microsatellite genotyping, as well habitat suitability analysis...
Microsatellites are polymorphic and cost-effective. Optimizing reduced microsatellite panels using heuristic algorithms eases budget constraints in genetic diversity population assessments. Microsatellite marker efficiency is strongly associated with its polymorphism quantified as the information content (PIC). Nevertheless, selection cannot rely solely on PIC. In this study, ant colony optimization (ACO) algorithm, a widely recognized method, was adopted to create an enhanced scheme for...
The thermal stress caused by global climate change adversely affects the welfare, productivity, and reproductive performance of farm animals, including chickens, causes substantial economic losses. However, understanding genetic basis indigenous chicken adaptation to high ambient temperatures is limited. Hence, reveal in this study investigated polymorphisms heat shock protein 70 (HSP70) HSP90 genes, known mechanisms cellular defense against local breeds red junglefowls Thailand. result...
The information on landscape connectivity among wildlife populations is crucial for conservation of endangered species. In this study, between core habitat areas was mapped and prioritized the potential corridors elephant in two separated regions Thailand. step selection function modeling approach employed to estimate resistance surfaces based occurrence data. Connectivity maps were created estimated by employing least-cost path circuit theory through a proposed analytical method. As results...
The domestication of wild animals represents a major milestone for human civilization. Chicken is the largest domesticated livestock species and used both eggs meat. originate from red junglefowl (Gallus gallus). Its adaptability to diverse environments ease selective breeding provides unique genetic resource address challenges food security in world impacted by climatic change population growth. Habitat loss has caused declines Thailand. However, diversity likely remain captive stocks. We...
Understanding the spatial ecology of an animal is crucial for its conservation and management, particularly threatened species. The gaur (Bos gaurus), globally classified as vulnerable, distributed across mainland South Southeast Asia. In Thailand, overall population decreasing, suitable habitats are declining. Conversely, well recovered in Khao Phaeng Ma Non-hunting Area (KPM-NHA), a part Dong Phayayen-Khao Yai Forest Complex, recognized UNESCO Natural World Heritage site. Due to abundance,...
In recent decades, a global acceleration of urbanization has been observed, leading to significant habitat loss and fragmentation. Economic development in eastern Thailand promoted, but this often coincided with unsustainable exploitation natural resources. The expansion urban industrial areas the region puts many organisms at risk extinction owing loss. Plakad-Pa Pak-Tawan-Ok (Betta siamorientalis) is an endemic species found only Thailand. study, genetic diversity population structure 17...
Understanding the genetic diversity of domestic chicken breeds under impact socio–cultural and ecological dynamics is vital for conservation natural resources. Mae Hong Son a local breed North Thai widely distributed in Province, Thailand; however, its characterization, origin, remain poorly understood. Here, we studied socio–cultural, environmental, aspects investigated allelic gene pool. We genotyped 28 microsatellite markers analyzed mitochondrial D-loop sequencing data to evaluate...
DNA barcoding without assessing reliability and validity causes taxonomic errors of species identification, which is responsible for disruptions their conservation aquaculture industry. Although facilitates molecular identification phylogenetic analysis species, its availability in clariid catfish lineage remains uncertain. In this study, was developed validated catfish. 2,970 barcode sequences from mitochondrial cytochrome c oxidase I (COI) b (Cytb) genes D-loop were analyzed 37 species....
