Abstract: D. butyracea (Fam: Sapotaceae) is an economically important tree with many uses of its different parts. In Arunachal Pradesh, D. butyracea is mainly found in subtropical regions of Tawang district adjoining to Bhutan. During the last 20 years, majority of the trees were dried up due to overharvesting. The seeds are recalcitrant and lose viability quickly after dispersal. The present study recorded 61 trees of which 50 plants were either dead or lost all branches and only 3 were saplings. The plant is facing great threat of becoming extinction from Tawang region. Proper in-situ and ex-situ conservation strategies and propagation techniques such as tissue culture are urgently needed.

Abstract: A survey was undertaken in the month of November and December 2012, to evaluate the species diversity of birds in D’Ering Memorial Wildlife Sanctuary (DWS). The study result in record of altogether 55 species belongs to 27 families from D’Ering Memorial Wildlife Sanctuary. Among the fifty nine species recorded, nine species are listed as threatened species in the IUCN red list. Out of the nine threatened species, three species fall in Critically Endangered (CR) category, four species fall in Endangered (EN) category and two species fall in Near Threatened (NR) category. Two species were recorded for the first time in the sanctuary. The record of 55 species in short period indicates that DWS is a highly diversity of bird species. Also, provide significant information on the distribution of threatened birds in Arunachal Pradesh, which would be first hand information to prioritize DWS as site in case of action to protect those recorded threatened species.

Abstract: Acmella paniculata (Wall. ex DC.) R.K Jansen (syn. Spilanthes paniculata DC.) belonging to the family Compositae (Asteraceae) has been reported to be used in traditional system of medicine among different tribal communities of the world as the plant is widely distributed across both tropical and subtropical nations. However in spite of its wide application in traditional medicine healing system, molecular characterization of this particular species has not been explored to date. Here a total of 15 landraces belonging to five populations of A. paniculata has been taken in order to establish genetic diversity within and among its populations through RAPD and ISSR marker. In case of RAPD a total of 325 bands were obtained in which 180 bands were monomorphic and 145 bands were polymorphic thereby showing 44.61% polymorphism while in case of ISSR a total of 129 bands were obtained in which 90 bands were monomorphic and 39 bands were polymorphic thereby showing 30.23% polymorphism. The average similarity matrix was used to generate a tree for cluster analysis by UPGMA method which showed higher genetic diversity in some of the populations of A. paniculata . ANOVA showed that genetic diversity of A. paniculata within population varied at around 74.67% while among population it varied around 25.33%.

Abstract: A field survey on Saturniid moths in West Siang district, Arunachal Pradesh was conducted from September, 2013 to August, 2014. Adult moths were recorded using compact fluorescent light of 18 W operated with a 230 V rechargeable battery. A total of 12 species viz., Attacus atlas Linn, Archaeoattacus edwardsi White, Samia canningii Hutton, Samia cynthia Drury, Actias selene Hübner, Actias maenas Doubleday, Actias parasinensis Brechlin, Antheraea assamensis Helfer, Antheraea frithi Moore, Loepa katinka Westwood, Cricula trifenestrata Helfer and Saturnia thibeta Westwood were recorded. The population of the wild Saturniids was found very less with a record of only 20 wild adults, 100 larvae and 200 cocoons. Felling of host plants for timber, anthropogenic forest fire, indiscriminate collection of the adult moths and dominance of parasitoids were identified as threats to the wild population of the saturniids.

Abstract: Indigenous trapping system is attached with the tribes of north east India, particularly to the people of Arunachal Pradesh as part of their life and culture. Apart from agriculture as the primary source, these people depend on animal trapping practices as secondary means of livelihood in day-to-day activities. The present work was carried out in East Kameng district of Arunachal Pradesh. People of this area are fond of hunting and fishing using indigenous traps. Almost all the tribes viz; Nyishi, Aka, Miji and Sulungs use the traps for catching preys. These practices are believed to be as old as the human races with close affinity. The simple structures with unique mechanisms these traps are used in certain periods of the year. The technique adopted is unique whose mechanism works on the scientific principle utilizing the restored stress force to trap the living organisms especially birds and mammals. The practice of trapping system is environment friendly, as because these can be used as and when required without damaging environment and climate. The trapping practice could be reasonably used for keeping ecological balance when the favourable season or environment arrives for rapid explosion of fauna and flora in the nature.

Abstract: The present study was designed to investigate the effect of crude bark extract of Oroxylum indicum in experimental prostatic hyperplasia in rat. The male animals were treated either corn oil or testosterone (10 mgkg-1) dissolved in corn oil and testosterone with crude bark extracts of Oroxylum indicum (50 and 100 mgkg-1) consecutively for three weeks. The protective efficacy of Oroxylum indicum on prostate hyperplasia was illustrated by prostate weight, prostatic index, percentage of inhibition and histological examinations. Crude extract of Oroxylum indicum caused significant reduction in the prostate weight and prostatic index when compared to testosterone induced BPH model group. Crude extract treated group also ameliorated the hyperplasia of prostate epithelium in a similar manner as was observes in finasteride (5 mgkg-1) treated group. The study indicates that Oroxylum indicum significantly reduced the progression of BPH and it may be an another phytotherapeutial source of drugs in BPH treatment.

Abstract: The diversity of butterflies are five families like Papilionidae, Pieridae, Nymphalidae, Lycaenidae and Hesperiidae along with their altitudinal preferences was monitored in ever green and semi evergreen forest in Talle Valley Wildlife Sanctuary of Arunachal Pradesh using transect count method have been followed. The maximum number of butterflies (64.70%) has been recorded within altitudinal ranges of 1600m-1800m. Sorensen’s similarity index has been calculated at 0.305 between 1600m-1800m and 1800m-2500m. Only 13.23% of butterflies are commonly observed in both altitudinal ranges. More species of Nymphalidae were recorded from this area than other families. The relationship between altitude, specific habitat and butterfly diversity are highlighted in this paper.
