چکیده

one of the most struggling issues for conservationists and wildlife managers is the climate change. this can be the necessity to develop climate condition indicators. due to the limited movements and special habitat conditions, pikas can be considered as reliable climate indicators. in this study, the most important climatic factors defining the distribution of this species were investigated to develop its distributional model for climatic change studies purposes and predicting wildlife movements. the distribution records of afghan pika in iran in combination with the presence/absence location data in 120 points, and climatic and elevation of those locations were analyzed using a binary logistic regression. the results depicted that the most important climatic factors that describe the presence of the afghan pika in iran are the monthly mean of the daily average temperature, average relative humidity, number of days with maximum 0ºc, and number of days with minimum -4ºc, and the altitude. the results suggest that this model can be used as the suitable habitats for this species.

Characterization of mitochondrial DNA from the pika (Ochotona rufescens rufescens).

Further to anatomical and physiological studies performed on the pika (Ochotona rufescens rufescens), a new laboratory animal, the main characteristics of the mitochondrial DNA from its liver are defined. The buoyant density of this DNA is 1.695 g/cm3, its length 5.30 mum,, i.e., 3.17 times that of the replicative form of phiX 174. It could have approximately 16 500 base pairs. The DNA from the...

Ochotona princeps (pika) myoglobin: an appraisal of lagomorph phylogeny.

Myoglobin was purified from skeletal muscle of the pika (Ochotona princeps) and its primary structure was determined. This sequence was added to the set of 64 already known vertebrate myoglobin sequences and used to evaluate the phylogenetic position of the pika among other mammals, using a computerized search procedure based on maximum parsimony criteria. The pika is clearly related to the rab...

A Modified Enrichment Method to Construct Microsatellite Library from Plateau Pika Genome (Ochotona curzoniae)

A microsatellite-enriched library of plateau pika (Ochotona curzoniae) was constructed according to the strong affinity between biotin and streptavidin. Firstly, genomic DNA was fragmented by ultrasonication, which is a major improvement over traditional methods. Linker-ligated DNA fragments were hybridized with biotinylated microsatellite probes, and then were subjected to streptavidin-coated ...
