Flying Squirrels Essay examples -- Biology, DNA

momentary squirrels is in subfamily Petauristinae. They be arboreal and nocturnal. They do not actually fly, unless glide between trees by a gliding tissue layer (patagium). This membrane connects the front legs to the back legs (Parr, 2003). In another word, a furry parachute-like membrane stretches from wrist to ankle. Flaps of skin connecting limbs to body provide a wing-like surface. entirely species have reddish eyeshine, brighter in the spectacular species than the smaller ones which may be quite dim. The subfamily shows severe taxonomic complications, with little agreement among mammalian researchers (Parr, 2003). elephantine flying squirrels (Petaurista sp.) have highest diversity in term of richness in cosmos in Southeast Asia. This species is large in size, being on average 422 mm long. The Red Giant Flying Squirrel is believed to mate doubly a year and the young are typically born in March or August in litters of 2 - 3 (Parr, 2003). The Indochinese constitute squ irrel (Menetes berdmorei) is a member of the family Sciuridae. The family has only 29 species of 14 genera in Thailand (Lekagul and McNeely, 1977, 1988 Par, 2003). The characteristics of the Indochinese screen background squirrel are black mid-dorsal stripe, two or three black stripe on the sides, and reddish brown fur on the back (Lekagul and McNeely, 1977, 1988 Par, 2003). realisation is more difficult during the dry season, however, when they are much less brightly colored. They have been found throughout Southeast Asia, from the east of Myanmar to Vietnam. As a ground squirrel, it is rarely found on trees, but spends most of the quantify in the thick underwoods of the rainforests. (Walston and Duckworth, 2008).The sizes of squirrels are variable between species. There are three types of... ...th at least one restriction enzyme and sequencing the ends of the resulting fragments using an Illumina Genome analyzer in order to sample the genomes of multiple individuals in a p opulation (Baird et al., 2008). The major advantage of RAD is that it gives information for a very large number of loci across the genome, and for the analogous loci in each individual sampled. The received method for accelerating targeted sequencing from ancient and highly degraded DNA includes the linking of multiplex PCR straightway with sample barcoding and high-throughput sequencing. The method creates the chance to generate umpteen kilobases of overlapping instalment data from 31 cave bear (Ursus spelaeus) ancient specimens at the same time (Stiller et al., 2010). It seems likely that in the future high-throughput sequencing technologies will have many advantages for the study of ancient DNA.
