Oroxylum indicum L. (Kurz.) is an ethno-medicinally important plant of North East India. In the present investigation, a comparative study was conducted to assess the AM fungal associations of Oroxylum indicum (L.) Kurz. each at two sampling locations of Jorhat district, Assam and Mon district of Nagaland, N. E. India. Comparatively higher root colonization (100±0) and maximum spore population (1239±13.4) were observed in the rhizospheric samples of Mon district, Nagaland, the region which is geographically more distinct and diverse than the other study location. The rhizospheric samples of Jorhat district showed relatively lower spore count and AM colonization. The Shannon-Weinner and Simpson diversity indices were measured as maximum (2.935 and 0.941 respectively) in samples of Mon district, Nagaland. The results of the present investigation indicated the effect of geographical variations, environmental selection as well as alterations of edaphic factors in changing the AMF populations associated with Oroxylum indicum, an ethno-medicinally important plant of NE India.

Increasing Trends

Accessing temporal trend of different meteorological parameters is essential for understanding the local climate changing pattern of a region. Quantitative estimates of the effect of climate change helps in understanding, planning, and management of water resources systems. In this study, monthly meteorological data were collected from 30 stations of north-east (NE) India for 1971–2010 and non-parametric Mann-Kendall (MK) test and Sen slope were employed for detection and quantification of significant temporal trends, respectively. An ESRI ArcGIS toolbar “ArcTrends” was used for the above mentioned tasks. The results obtained for rainfall were of mixed nature and both increasing and decreasing significant trends were found for different stations in different months. Most of the negative trends were found in the months of July–August (monsoon), whereas, more stations showed positive trends in April–May (pre-monsoon), and October–November (post-monsoon), indicating inter-seasonal shifting of rainfall without much change in the annual total. Number of rainy days was found to have positive trends in March–May (pre-monsoon) and negative trends in September–December. Except some positive trends during June–December in Manipur and Meghalaya, there were no significant trends in maximum temperature. In some stations, minimum temperature was found to have significant increasing trends throughout the year indicating a general rising trend in NE India. Some major towns like Guwahati, Imphal, Agartala and Kailashshahar showed significant positive trends in mean temperature, mostly during June–December. Mean relative humidity was, in general, found to be significantly increasing, especially during February–March. In some stations, wind speed was found to have significant negative trends throughout the year, with Agartala being the most affected.

The Comparative Study

The Multidimensional Poverty Index (MPI) applies the direct method of measuring poverty using the Alkire and Foster (AF) approach. The study aims at analyzing the comparative study and trends of the multi-dimensional poverty among the north eastern states of India. The MPI value was continuing to be higher in Assam and Meghalaya over the decade (2005-06 to 2015-16). Vulnerability to poverty was estimated to be lower in Mizoram over the decade as compared to all India level. On the other hand, severity of poverty was higher in two states, Assam and Meghalaya as compared to the all India estimate (8.8%) between 2005-06 and 2015-16. In can be concluded Assam, a gateway to north east India, remains as multidimensionality poor as compared to all states of NE India. Vulnerability and severity of poverty are higher in Assam over the decades among the NE States. Thus, it is recommended for pro-poor strategy for Assam in health, education and standard of living to come out of multidimensional poverty.

ABSTRACTBackgroundVector borne infectious diseases affect two third of the world’s human population and cause mortality in millions each year. Malaria remains one of the major killers in the Indian sub-continent and transmitted uninterruptedly by many efficient vectors and their sibling species. In North East India (NE), Anopheles minimus has been recognized as an important vector which shares majority of malaria cases. This study primarily focuses on to recognize the presence and distribution of sibling species of An. minimus in certain endemic area of NE India.MethodsAnopheles species were collected and identified using available morphological keys. The genomic DNA was extracted from the mosquito specimen and used to perform species specific PCR (ss PCR) for molecular identification of major malaria vector An. minimus sibling speciesResultMorphological identification suggested the presence of An. minimus sl in low density in the study area. The specimen of An. minimus subjected to ss PCR confirmed the prevalence of only one sibling species namely, An. minimus A in Sialmari and Chandubi.ConclusionThough in low density, but malaria vector An. minimus is still present in certain endemic areas of NE India. The ss PCR assay employed presently suggested that An. minimus sibling species A is prevailing in the region. Presently used ss PCR assay was simpler, faster, cheaper and more readily interpreted than earlier assays. This information could be useful in understanding of current prevalence and distribution of An. minimus sibling species complex in NE region of India.

Gabbroic Intrusion

Mafic intrusive within Neoproterozoic carbonates of Miri-Buxa Group in the Panging area of the Arunachal Lesser Himalaya, NE India has been reported for the first time. These mafic rocks have affinity to subalkaline-Mg-tholeiites and identified as low-Ti gabbro. Geochemically they are characterized by enrichment in LILE and LREE, depleted in HFSE with minor REE fractionated nature [(La/Yb)N = 2.70-3.29)] and positive Eu anomalies (Eu/Eu* = 1.00-1.30). These rocks have the influence of a within plate signature which were intruded in a continental rift tectonic environment. Petrogenetic modelings of [Mg]-[Fe] and REE suggest these mafic rocks probably derived from enriched mantle source similar to komatiitic composition at moderate to higher degree (35% - 50%) of partial melt. Based on the present reported microfossils viz. Rivularia haematites and Filamentus cyanobacteria in the chert lenses of the Buxa Dolomite from the Panging area, it is suggested that the gabbroic intrusion might have been taken place during Late Neoproterozoic which is probably close to the Precambrian–Cambrian boundary.

Big Push

The North-East India (NEI) consists of eight states and it is a ‘mixed bag’ of several ethnic groups. The region is known for its unexploited natural and human resources which are the basic factors of economic development. So, the energetic entrepreneurs are necessary if we want to harness it properly. With the emergence of Globalization and more recently with the inception of ‘Look East Policy’, trade and commerce has become an important tool in linking this region with the Asian and South East Asian countries. Look-East Policy is expected to provide an opportunity to overcome the problem of distance from big markets. It is apparent that NE India as a whole needs a big push or a kick starts to launch the economy on the development path through trade and commerce. But, it is greatly handicapped by law and order situation or bandh and blockade in the region. Economic development of a region is quite illusive agenda without developing trade and commerce in the region. Peaceful environment in the region is the pre-requisite condition for economic development. Keeping this in mind, the question that arises is who will be the active agents in bringing peace in the region?

The development of the rubber sector in North East (NE) India in recent decades is an outcome of the government’s import substitution initiatives in the post-independence period. The article attempts to trace the process of evolution and development of the rubber sector in the region and observes that the adopted policies for rubber expansion had been framed under the narrow innovation system model, whereby the localised knowledge and learning, as well as practices, remained completely ignored in the promotion of the sector. The lack of region-specific rubber development strategies with appropriate linkages supported by institutional systems are the critical gaps that undermine the sustainable growth of the rubber sector in the NE region. Eventualities of the sort call for reinventing policies and programmes under the broad innovation system framework, so as to reap the advantages emanating from the integration of the region with the global market and facilitate greater diversification and sustainable growth of the rubber sector.

Abstract The present investigation is a novel approach of exploring the endophytic fungal diversity of Elaeagnus latifolia L., an actinorhizal plant species of North-east India and evaluation of its biocontrol potential against Pestalotiopsis theae, the causal agent of grey blight disease in tea. A total of 17 endophytic fungal species belonging to 12 families and 03 orders were isolated from various parts of E. latifolia L. Isolates were identified based on colony morphology, spore and fruiting bodies using microscopical tools and techniques. Nigrospora sp. showed highest species density (0.5) among all the isolates. Isolation frequency was maximum (67%) in case of Fusarium sp., Nigrospora sp., Penicillium chrysogenum and Rhizopus sp. More fungal isolates were obtained from root and stem (47% each) as compared to leaves (29%). Species richness and diversity indices was maximum (15.0) in stem and minimum (9.0) in leaves. Highest Shannon and Simpson diversity index was in stem (2.02 and 0.860 respectively) followed by root (1.979 and 0.847 respectively) and least in leaves (1.494 and 0.75 respectively). Among the isolates tested for plant growth promoting parameters, EF09 (Fusarium sp.) showed positive response for all the tested parameters. The isolate, EF09 also showed maximum antifungal potential (up to 87.1%) against P. theae in poisoned food technique. Enumeration of endophytic fungal diversity of E. latifolia L. holds promises as the putative strains may lead to the isolation of novel bioactive components for use in industry, medicine and agriculture.

Worldwide and in India, malaria elimination efforts are being ramped up to eradicate the disease by 2030. Malaria elimination efforts in North-East (NE) India will have a great bearing on the overall efforts to eradicate malaria in the rest of India. The first cases of chloroquine and sulfadoxine-pyrimethamine resistance were reported in NE India, and the source of these drug resistant parasites are most likely from South East Asia (SEA). NE India is the only land route through which the parasites from SEA can enter the Indian mainland. India’s malaria drug policy had to be constantly updated due to the emergence of drug resistant parasites in NE India. Malaria is highly endemic in many parts of NE India, and Plasmodium falciparum is responsible for the majority of the cases. Highly efficient primary vectors and emerging secondary vectors complicate malaria elimination efforts in NE India. Many of the high transmission zones in NE India are tribal belts, and are difficult to access. The review details the malaria epidemiology in seven NE Indian states from 2008 to 2018. In addition, the origin and evolution of resistance to major anti-malarials are discussed. Furthermore, the bionomics of primary vectors and emergence of secondary malaria vectors, and possible strategies to prevent and control malaria in NE are outlined.

Abstract. Hussain JF, Tynsong H. 2021. Review: Ethno-zoological study of animals-based medicine used by traditional healers of North-east India. Asian J Ethnobiol 4: 1-22. Since ages, plants and animals have been used in human cultures as therapeutics. Animals have not only acted as a source of food for humans, but have also been commonly used in applications such as medicine, clothes, and other related services. The use of animals and animal products in traditional methods of treating diseases, and for many other reasons, dates back to the early days of civilization. Treatment of human diseases using animal-derived products is called zootherapy or ethno-zoology. Despite the worldwide utilization of ethno-zoology in the form of traditional medicines based on animals, a thorough and comprehensive study of zootherapy in comparison to plant-based medicinal research is still ignored. This study is an attempt to highlight available knowledge on ethno-zoological therapeutic applications used by different traditional healers of North-East (NE) India. With regard to the frequency of animal species, the use of mammals and mammalian products is found to be the highest in NE India as compared to other animal groups, while use of fish-based medicine in the state of Manipur is prevalent compared to other animal species. In Arunachal Pradesh, use of insects is high in traditional medicines.
