“…The shrubs and grasses found in HT are nourished by photosynthesis that takes place on the forest floor in open canopy areas ( Evans et al 2018 ). Elephants move within safe habitats and easily avoid disturbances, such as HS, because the environment in protected primary forests has dense vegetation ( Talukdar et al 2020 ). The paired t-test showed that LF–HT had a significant difference in the identified plant taxa ( P = 0.003).…”

Human–elephant conflict (HEC) contributes to the increasing death of Asian elephants due to road accidents, retaliatory killings and fatal infections from being trapped in snares. Understanding the diet of elephants throughout Peninsular Malaysia remains crucial to improve their habitat quality and reduce scenarios of HEC. DNA metabarcoding allows investigating the diet of animals without direct observation, especially in risky conflict areas. The aim of this study was to determine: i) the diet of wild Asian elephants from HEC areas in Peninsular Malaysia using DNA metabarcoding and ii) the influence of distinct environmental parameters at HEC locations on their feeding patterns. DNA was extracted from 39 faecal samples and pooled into 12 groups representing the different sample locations: Kuala Koh, Kenyir, Ulu Muda, Sira Batu, Kupang-Grik, Bumbun Tahan, Belum-Temengor, Grik, Kampung Pagi, Kampung Kuala Balah, Aring 10 and the National Elephant Conservation Centre, which served as a positive control for this study. DNA amplification and sequencing targeted the ribulose-bisphosphate carboxylase gene using the next-generation sequencing Illumina iSeq100 platform. Overall, we identified 35 orders, 88 families, 196 genera and 237 species of plants in the diet of the Asian elephants at HEC hotspots. Ficus (Moraceae), Curcuma (Zingiberaceae), Phoenix (Arecaceae), Maackia (Fabaceae), Garcinia (Clusiaceae) and Dichapetalum (Dichapetalaceae) were the highly abundant dietary plants. The plants successfully identified in this study could be used by the Department of Wildlife and National Parks (PERHILITAN) to create buffer zones by planting the recommended dietary plants around HEC locations and trails of elephants within Central Forest Spine (CFS) landscape.

“…Based on suitability of settlements, this paper discusses the sustainable development and planning optimization of settlements (Liu et al, 2020;Ru no et al, 2019;Ali and Ahmad, 2020). Suitability is the basis of the development and layout of settlements (Buruso, 2018;Fabrizio et al, 2019;Anand et al, 2020;Talukdar et al, 2020), which is closely related to the sustainable development of settlements (Wang et al, 2020;Megahed, 2020;Da Costa et al, 2018).…”

“…Human settlements is the result of human activities on the natural environment (Anand et al, 2020), including natural elements and humanistic elements (Ejigu and Tassie, 2020;Milanesi et al, 2015;Buruso, 2018;Megahed, 2020;Habibie et al, 2019). Natural elements are the basis of settlements layout development, and humanistic elements are also the pillar of settlements development (Hansen et al, 2020;Talukdar et al, 2020;Da Costa et al, 2018;Torretta et al, 2020). However, at present, most of the researches on the suitability settlements focus on the natural suitability of settlements (Hu et al, 2020), and consider the humanistic indicator of settlements (Zhang et al, 2018;Liu et al, 2020;Fuller et al, 2018;Omar and Raheem, 2016;Tezer et al, 2020;Cui et al, 2017;Yan et al, 2017).…”

The comprehensive suitability of regional human settlements is of great significance to the development and spatial distribution of regional human settlements and regional social and economic development. In this study, based on the traditional evaluation of the natural suitability of the human settlements, this study adds humanistic indicators to comprehensively evaluate the suitability of the human settlements in Liaoning, China. In particular, we sought to uncover the spatial differentiation law of the comprehensive suitability of these settlements and its correlations with population density and GDP density, provide a theoretical basis for urban human settlements planning and governance. The main conclusions were as follows: (1) the natural suitability index in Liaoning Province presents the law of longitudinal spatial differentiation from northeast to southwest, which follows the direction of the mountains; (2) the highest to lowest humanistic suitability indexes were as follows: the central, eastern, and western regions; (3) the highest to lowest spatial differentiations of the comprehensive suitability of the human settlements were as follows: the central and coastal, eastern, and western regions;(4) the spatial distribution of population–economy density in Liaoning Province was basically consistent with the spatial distribution of the comprehensive suitability index of human settlements, The population economy is concentrated in the areas with the best and moderate human settlements. Ultimately, we found that the distributions of population–economy and human settlement suitability were relatively coordinated and that highly suitable land was already fully utilized.

“…Many oristic studies have been undertaken in the state of Assam. Plant diversity, population structure and regeneration status were investigated in the four tropical forests in Barak Valley Hojai (Borah et al, 2011), Reserve Forest and Kumortoka Reserve Forest (Dutta and Devi, 2013), comprehensive population structure of tree species in Hollongapar Gibbon Wildlife Sanctuary (Sarkar and Devi, 2014), reserve forests and private tropical forests of Barak Valley (Borah et al, 2016) and Bornewria forest, Assam (Barua et al, 2018).However, only few studies has been conducted for Patharia Hills Reserve Forest (PHRF) such as assessment of forest health (Talukdar et al, 2019), biodiversity of mushrooms (Vyas et al, 2014), importance of non-timber forest products (Talukdar et al, 2020a)and a few signi cant zoological studies like habitat suitability of the Asiatic elephant in the trans-boundary (Talukdar et al, 2020b), conserving wildlife wealth (Talukdar et al, 2017), as this reserve forest has always been ignored due to trans-border location (with Bangladesh) which is fairly inaccessible. Considering the gap in the study, the PHRF was selected as the study site for the dissertation work.…”

An investigation was undertaken to compare the diversity and community characteristics of trees in natural (NFS) and planted (PFS) forest stands of Patharia Hills Reserve Forest of Barak Valley (PHRF), Assam by random quadrat method. A total of 68 tree species belonging to 50 genera and 30 families were recorded from the two stands. Out of which, 67 species (49 genera and 29 families) were recorded from the NFS and 7 species (7 genera and 6 families) were recorded from the PFS respectively. The IVI revealed that in the NFS, Artocarpus lakoocha Roxb. (31.70) was the most dominant species and in the PFS, Tectona grandis L.f. (175.39) was the most dominant species. The total density was recorded to be 740 trees ha-1 and 770 trees ha-1in the NFS and PFS respectively. The Shannon-Weiner index, Simpson index, Margalef’s richness index and Pielou’s evenness index were recorded to be 3.7, 0.04, 11.16 and 0.88 respectively for the NFS; and 1.41, 0.37, 1.10 and 0.72 respectively for the PFS. The disturbance index was 32.22% in the PFS. The Sorensen’s similarity index was 16%. Population dynamics of trees revealed that the regeneration status of the NFS was much better than that of the PFS. Hutchenson’s t-test revealed that the NFS and the PFS were significantly different (P<0.001) in terms of tree species diversity. To avoid the rapid destruction of the forest in general and planted forest in particular, implementation of strict regulations and protective measures is urgent.
