an attempt has been made to analyze the distribution of the beta-lactoglobulin genotype in swamp buffaloes and murrah buffaloes utilizing polymerase chain reaction-restriction fragment length polymorphism(pcr-rflp). blood samples were taken from 50 swamp buffaloes and 50 murrah buffaloes. the dna was extracted by the phenol-chloroform method. the pcr-rflp was performed using beta-lactoglobulin ...

In this study the nucleotide diversity in the 5'untranslated region (UTR) of TLR8 gene in riverine as well as swamp buffaloes has been described. Analysis of the 5'UTR of TLR8 gene showed presence of two SNPs in this region, g.-139G>T and g.-128A>G. A PCR-RFLP assay designed for genotyping of g.-139G>T SNP across 667 samples from 2 buffalo populations revealed a striking difference in allele fr...

The existence of monodominant forests on well-drained soils in tropical regions has been widely reported. Such forests most likely result from a combination of both ecological and evolutionary factors. Under conditions of high seed and seedling mortality, vegetative reproduction could create a reproductive advantage leading to forest dominance, and profoundly affect the distribution of genetic ...

In Lake Nabugabo, Uganda, a satellite of Lake Victoria, approximately 50% of the indigenous fishes disappeared from the open waters subsequent to the establishment of the introduced predatory Nile perch, Lates niloticus. This pattern is similar to the faunal loss experienced in the much larger Lake Victoria. Several of these species persisted in wetland refugia (e.g. ecotonal wetlands, swamp la...

in this study, we focused on detailed studies on micromorphological and mineralogical properties of three types of peat and swamp, to compare these different ecological area together. to achieve this goal, samples from a highland peat swamp (ghaleh-ghafeh ps), a peat swamp forest (suteh psf) and a costal swamp (galougah cs) in golestan province, north of iran have been considered. these studies...

The complete coding region sequence of the SRY gene in Chinese swamp buffalo was determined by PCR product sequencing. Comparison of swamp and river buffalo SRY gene sequences revealed a single nucleotide polymorphism (SNP, C/G) at the 202 bp site of the coding region. Further, a total of 124 male domestic buffaloes were genotyped at this SNP site using the PCR-SSCP method, and it was found tha...

Since the 1990s, possibly earlier, large numbers of Asian swamp eels (Synbranchidae: Monopterus spp.), some wild-caught, have been imported live from various countries in Asia and sold in ethnic food markets in cities throughout the USA and parts of Canada. Such markets are the likely introduction pathway of some, perhaps most, of the five known wild populations of Asian swamp eels present in t...

Between August 2000 and August 2001, 12,216 fish of 73 species were purchased from several local markets in Nakhon Nayok Province, Thailand, and examined for the presence of Gnathostoma larvae. Almost all species were fresh-water fish that had grown naturally, rather than raised commercially. Eight species were found to be infected with gnathostome larvae. The overall prevalence was 5.1% (626/1...

Tropical peat swamp lands in the Southeast Asia which store tremendous large amount of carbon in their peat layer and abundant biodiversity are now endangered by human activities such as deforestation, forest fires, land development and urbanization. To earlier start a better environmental policy for conservation of nature of the tropical peat swamp area is one of the preferential global issues...
