Field surveys were conducted between 2015-2018 to determine the occurrence and distribution of PNRSV infecting peach in 40 orchards representing major peach producing districts of Himachal Pradesh Symptomatic trees typical of viral infection present in all the orchards surveyed exhibited chlorotic spots, necrotic rings, leaf deformation and shot hole symptoms with an incidence ranging from 1 to 47 percent. DAC-ELISA confirmed the association of an Ilarvirus with peach cv.

Papaya ring spot virus (PRSV) is the most destructive disease of Papaya, responsible for yield reduction of Papaya all over the world. PRSV exhibited different types of symptoms on Papaya plant in the field like ringspot , vein clearing, vein banding, chlorosis of younger leaves, filiformy, shoestring, mosaic, mottling, stunted growth etc. Molecular diagnosis of PRSV was done with the help of gene specific primers through PCR. Gel electrophoresis results show a 300bp clear band which confirms the presence of PRSV in the plants. Sequencing was done and phylogenetic tree was made.

Kachchh, the largest district of Gujarat has very fragile environment and poor natural resources. Under such conditions, the cultivation of perennial component of vegetation, particularly the fruit trees, would provide opportunity for sustainable source of livelihood to the inhabitants of the region. Kachchh has about 18 percent potential area to grow fruit trees but under the aforesaid environment and edaphic conditions, the establishment, growth and economic life remain poor.

The population distribution of Assamese monkey Macaca assamensis were studied in Nagarjun forest of Shivapuri Nagarjun National Park, Nepal and data collected during Dec. 2013 and January 2014, by scan sampling methods along with transect walk through forest trails and ring-road of forest.. Seven bisexual troops were observed in subtropical/lower temperate forest of Nagarjun forest especially around Raniban forest area. The observed smallest troop was with 9 individuals while the largest troop had 37 (41) individuals of different age. The average troop size is 20.57.

Bakernema enormese sp. n., collected from rhizosphere of forest wood trees in Muong Phang, Dien Bien Province (north Vietnam) is described and illustrated. The new species is characterized by large body size and stylet. In general, this new species is close to two existing species of the same genus, B. inaequale and B. dauniense by cuticle structure in transparent membranous projections which appear in lateral view as spine-like structures on each annulus. These structure arranged into several rows along the body. In morphology, the new species differs from B. inaequale and B.

The first forest fire history of the Burabai Region (Kazakhstan) from tree rings of Pinus sylvestris
Forest fires are one of the most important events causing an abrupt decrease in tree-ring width. Although humans are the main cause of forest fires, extreme weather or climate change may promote the frequency and severity of fires. The purpose of this study is to reconstruct historical fires in the Burabai Region of Kazakhstan including their frequency and seasons.
