Based on an ethnozoological study carried out from December 2018 to November 2019, this paper attempts to document the usage of squirrel species for various purposes by the Adi, Idu Mishmi, Miju Mishmi, Tangsa, Chakma and Monpa tribe living near the villages adjoining the protected areas located in the districts of East Siang, Lower Dibang Valley, Dibang Valley, Lohit, Changlang and West Kameng of Arunachal Pradesh, India. The paper also describes the use of certain squirrel species as a part of their traditional culture and lists their names in English, Vernacular and Latin names. The study has led to an understanding that eight squirrel species are used by the tribes for cultural, food and medicinal purposes. This work contributes to ethnozoological research by describing a knowledge system of squirrel species use and the association of squirrel species with the cultural believes of the tribes.

<div> <p>One of the first order questions regarding a cross-section representation through a fold-thrust belt (FTB) is usually “how unique is this geometrical interpretation of the subsurface?”  The proposed geometry influences perceptions of inherited structures, decollement horizons, and both rheological and kinematic behavior.  Balanced cross sections were developed as a tool to produce more accurate and thus more predictive geological cross sections.  While balanced cross sections provide models of subsurface geometry that can reproduce the mapped surface geology, they are non-unique, opening the possibility that different geometries and kinematics may be able to satisfy the same set of observations. The most non-unique aspects of cross sections are: (1) the geometry of structures that is not seen at the surface, and (2) the sequence of thrust faulting.  We posit that integrating sequentially restored cross sections with thermokinematic models that calculate the resulting subsurface thermal field and predicted cooling ages of rocks at the surface provides a valuable means to assess the viability of proposed geometry and kinematics.  Mineral cooling ages in compressional settings are the outcome of surface uplift and the resulting focused erosion.  As such they are most sensitive to the vertical component of the kinematic field imparted by ramps and surface breaking faults in sequential reconstructions of FTB.  Because balanced cross sections require that the lengths and locations of hanging-wall and footwall ramps match, they provide a template of the ways in which the location and magnitude of ramps in the basal décollement have evolved with time.  Arunachal Pradesh in the eastern Himalayas is an ideal place to look at the sensitivity of cooling ages to different cross section geometries and kinematic models. Recent studies from this portion of the Himalayan FTB include both a suite of different cross section geometries and a robust bedrock thermochronology dataset. The multiple published cross-sections differ in the details of geometry, implied amounts of shortening, kinematic history, and thus exhumation pathways. Published cooling ages data show older ages (6-10 Ma AFT, 12-14 Ma ZFT) in the frontal portions of the FTB and significantly younger ages (2-5 Ma AFT, 6-8 Ma ZFT) in the hinterland. These ages are best reproduced with kinematic sequence that involves early forward propagation of the FTB from 14-10 Ma.  The early propagation combined with young hinterland cooling ages require several periods of out-of-sequence faulting. Out-of-sequence faults are concentrated in two windows of time (10-8 Ma and 7-5 Ma) that show systematic northward reactivation of faults.  Quantitative integration of cross section geometry, kinematics and cooling ages require notably more complicated kinematic and exhumation pathways than are typically assumed with a simple in-sequence model of cross section deformation.  While also non-unique, the updated cross section geometry and kinematics highlight components of geometry, deformation and exhumation that must be included in any valid cross section model for this portion of the eastern Himalaya.</p> </div>

AbstractThe loss of tropical forests and associated biodiversity is a global concern. Conservation efforts in tropical countries such as India have mostly focused on state-administered protected areas despite the existence of vast tracts of forest outside these areas. We studied hornbills (Bucerotidae), an ecologically important vertebrate group and a flagship for tropical forest conservation, to assess the importance of forests outside protected areas in Arunachal Pradesh, north-east India. We conducted a state-wide survey to record encounters with hornbills in seven protected areas, six state-managed reserved forests and six community-managed unclassed forests. We estimated the density of hornbills in one protected area, four reserved forests and two unclassed forests in eastern Arunachal Pradesh. The state-wide survey showed that the mean rate of encounter of rufous-necked hornbills Aceros nipalensis was four times higher in protected areas than in reserved forests and 22 times higher in protected areas than in unclassed forests. The mean rate of encounter of wreathed hornbills Rhyticeros undulatus was twice as high in protected areas as in reserved forests and eight times higher in protected areas than in unclassed forests. The densities of rufous-necked hornbill were higher inside protected areas, whereas the densities of great hornbill Buceros bicornis and wreathed hornbill were similar inside and outside protected areas. Key informant surveys revealed possible extirpation of some hornbill species at sites in two protected areas and three unclassed forests. These results highlight a paradoxical situation where individual populations of hornbills are being lost even in some legally protected habitat, whereas they continue to persist over most of the landscape. Better protection within protected areas and creative community-based conservation efforts elsewhere are necessary to maintain hornbill populations in this biodiversity-rich region.

Arunachal Pradesh, the 13th geographically largest frontier State of India covering an area of 83,743 sq. km. in hilly terrain of Eastern Himalayas having population of 13,82,611 persons has 3,863 villages, living 77.33% in rural areas and 43%  BPL (2011 Census). The territory was called “Terra Incognita” or   No Man’s Land till the beginning of the 20th century. Here, the process of development initiated around thirty years back. Due to absence of private sector unemployment has been rising rapidly.         Monpa is one of the 25 major tribes. They are inhabitant of West Kameng and Tawang districts, Buddhists by religion. Traditional industries occupy a place of fundamental importance in the lives of this tribe although this feature stands equally true for the other tribes of the State too. The present researcher has intimately lived with them for couple of years in fulfilling the mandate of an Industrial Extension Officer. The wonderful carpets,  wood carving, mask making, bamboo baskets slung over the forehead of Monpa Women, their stone built houses, the unique atta chakkis (flour mills) operated by water power for grinding wheat, barley and millet into fine flour,  bokpoi (millet halwa) made out of it, the hand-made paper manufactured from the bark of sugu tree (dapne botanica), the compost made out of leaves of oak forests (parmong) used as fertilizer makes their agro-produce organic, the medicinal herbs, thankhas (holy scroll painting), red coat made out of best wool, the traditional headgear ( a cap made of black yak’s hair with five long fingers protruding all around), traditional Monpa shoes, intricately carved and beautifully painted vessels are all best testimonies witnessing the relevance of traditional industries in their deeper socio-economic ethos. The Monpas are shrewd, cultured and thrifty by nature which is considered as essential traits of entrepreneurs. Without appropriate interventions these traditional industries may become extinct a day as the contemporary generation are less attracted towards these activities for its commercial gains are not well established and the profession has not acquired a respectful status in the modern system.    The empirical study, therefore, aims to access the present scenario of these brilliant traditional industries, its financial aspects, its relevance in the development process, to seek the problems faced, it’s probable solutions and needed interventions as there is no in depth study on these issues till date under the sub-theme Rural livelihood markets and economies. Review of literature, collection of data from primary and secondary sources, documentations and researcher’s field experience etc. are the key references of the study.___________

A thin linear belt of Permian Lower Gondwana rocks occur in the Eastern Himalayas from Arunachal Pradesh to Sikkim. The Lower Gondwana Group of rocks consists of shale, siltstone, sandstone, carbonaceous shale and coaly matter and is sandwiched between Miri Group and Siwalik Group of rocks. Heavy mineral composition of sandstones is extensively used in the provenance studies as they are the surviving remnants of the rather abundant but unstable mafic components of the source rock. The sandstones of Lower Gondwana Group bear the heavy mineral assemblage of chlorite, biotite, zircon, ilmenite, epidote, garnet, amphibole, chloritoid, brown tourmaline, magnetite, staurolite, rutile, and opaques which is indicative of a provenance of metamorphic rocks with input of igneous rocks. Provenance sensitive mineral index ratios were also calculated to see the variation in the ratio of two or more stable minerals with the same characteristics.

The article considers a number of works by Gennady Stepanovich Rayshev as historical and ethnographic sources. The subject of the research is the components of his ethnic consciousness. The goal is to analyze the creative work of the Khanty artist as an original historical and ethnographic source reflecting the ethnic identity, the mentality of the indigenous people of the North and the features of the modern epoch. The research materials are based on the visual, historical and cultural analysis of graphic and pictorial canvases and principal statements of G. S. Rayshev on the problems of artistic creation. The analysis of Rayshev’s creativity shows how the intelligentsia of national minorities retransmits and transforms old and new myths. With the disappearance of traditional culture, the myth has not disappeared. Its forms changed, carriers changed radically, but deep structures were preserved. The myth still exists, although it has changed appearance. When different cultures “meet”, this allows creative personalities to act as mediators between the former mythical array and modernity. Without losing previous ties with their native culture, they are engaged in verbal or pictorial design of the worldview, feelings and thoughts of their ethnic group, and reflect their history and cultural realities. The horizons of artists are much wider compared to ordinary people. They retain ethnic stereotypes, knowledge about life and elements of everyday life that determine the specifics of people’s life longer. Their works have not only artistic value, but also the properties of a historical and ethnographic source. Keywords: graphics, painting, source, G. S. Rayshev, traditional culture, artist, ethnos
