the purpose of this research was to classify buffaloes from different areas of the two azari (west and east azarbayjan and ardabil provinces) and north (guilan province) ecotypes using support vector machine method. a total of 258 buffalo were sampled and genotyped using the axiom buffalo 90k genotyping array at the parco technologic padano lab in italy. two metric methods of cross validation a...

It is about 50 years that FMD affected the ruminants of Isfahan. Last outbreaks of FMD were happened at 2005 even vaccinated animals, so in current work using RT-PCR, sequencing and regression "r" values, the isolated strains in Isfahan were identified. The aim of this study was molecular epidemiology of FMDV in Isfahan province as the central part of Iran in 2006-2009. According to the result ...

A study was conducted to investigate structural and functional modifications in three differently adapted ecotypes of Aeluropus lagopoides (Linn.) Trin. ex Thw. under saline conditions. Two ecotypes were collected from moderately saline Bailahwala Dahar (BD) and heavily salt-affected Ladam Sir (LS), respectively while one ecotype was selected from least saline Derawar Fort (DF), which was consi...

The cyanobacterium Prochlorococcus numerically dominates the photosynthetic community in the tropical and subtropical regions of the world's oceans. Six evolutionary lineages of Prochlorococcus have been described, and their distinctive physiologies and genomes indicate that these lineages are "ecotypes" and should have different oceanic distributions. Two methods recently developed to quantify...

Inhibition of photosynthesis and epidermal damage resulting from ultraviolet irradiation were assessed for arctic and alpine plant species. These species were taken from a latitudinal gradient of the arctic-alpine life zone from the Andes to northern Alaska, which spans a steep change in solar UV-B irradiation (280 to 320 nm). Ecotypes and species from the Arctic, where solar UV-B flux is very ...

The process of plant speciation often involves the evolution of divergent ecotypes in response to differences in soil water availability between habitats. While the same set of traits is frequently associated with xeric/mesic ecotype divergence, it is unknown whether those traits evolve independently or if they evolve in tandem as a result of genetic colocalization either by pleiotropy or genet...

The broadly defined species of bacterial systematics frequently contain unnamed and unrecognized populations (ecotypes) differing in physiology, genome content, and ecology. Without formal recognition of such ecotypes, it is difficult for microbial ecologists to detect replacement of one ecotype by another in the face of global warming. The ecotype simulation algorithm has proved capable of sup...

Ecotypes are the result of ecological differentiation at early stages speciation. Adaptation to soil conditions offers arguably best examples local adaptation in plants. Two sympatric ecotypes, with either a red or green abaxial leaf surface, were found without clear geographical isolation Phalaenopsis pulcherrima, Southeast Asia endemic and endangered orchid. The ecotype has higher water conte...
