Birds play various crucial roles in the ecosystem including pollination, seed dispersal, and pest control. Assemblages of bird species in a particular landscape are useful predictors in various ecosystem services, this is evident from studies of forest bird assemblages, aquatic bodies and agro ecosystems. For developing conservation strategies, information on bird species assemblages in a particular geographical area is important. Diversity in aquatic ecosystem support a diversity of water bird species. In the present study, around 45 bird species were recorded in 21 aquatic bodies in Bankura, West Bengal, India, in which two species, namely, Leptoptilos javanicus and Aythya ferina declared 'Vulnerable' and three species such as Mareca falcata, Threskiornis melanocephalus, and Limosa limosa considered as 'Near Threatened' according to the IUCN Red list. Dendrocygna javanica and Nettapus coromandelianus were found to be the most abundant. In those 21 study areas, site6 has the highest species richness and site2 has the lowest. The dominance index was highest for site2 and lowest for site6. Pielou's index of evenness was highest for site20. The rarefaction curve showed species abundance was highest for site1. Classical cluster analysis for species abundance showsthat site20, site21, site3, site8, site4, site19, site5, site14, site12, site15, site7, site 10 site11, and site13 are closely related. This paper is aimed to generate interest among people to conserve aquatic birds and their habitats and to document baseline information for further study. [ABSTRACT FROM AUTHOR]

This paper deals with the description of a new Anthaxia (subgenus Haplanthaxia Reitter, 1911) species from southern India, which belongs to the Anthaxia (H.) winkleri Obenberger, 1914 species-group: Anthaxia (H.) keralensis sp. nov. In addition to a morphological description, we also generated mt. COI DNA sequences and discuss the results of a phylogenetic analysis of the new species with previously deposited COI DNA sequences of Anthaxia spp. In a maximum-likelihood phylogenetic analysis, the new species shared the same hypothetical ancestor node with A. melancholica Gory, 1841 and similar molecular characteristics (~48% similarity) with A. tenella Kiesenwetter, 1858 and A. corinthia Reiche & Saulcy, 1856. More systematic studies are required to understand the species diversity, distribution, biology, and evolutionary significance of the Anthaxia (H.) species groups. [ABSTRACT FROM AUTHOR]

The road network is spreading rapidly in human dominated as well as forested areas in India. Roads passing through forested areas are known to negatively impact wildlife populations by contributing to wildlife-road kills besides causing habitat fragmentation, soil erosion, and disruption of gene flow. This paper documents encounters of wildlife road kills on the State Highway 26 (SH 26) passing through the forested area of Khandwa Territorial Forests in central India. Between October 2015 and June 2017 and from November 2021 to June 2022 we collected opportunistic data on wildlife mortalities on SH 26. We recorded 61 wildlife mortalities on a stretch of 34 km of SH 26. Of the road kills encountered, 71% were birds, 21% were mammals, and 8% were herpetofauna. Highest among bird kills were members of nightjars (Caprimulgidae) (26%) and owls (Strigidae) (23%). Among owls, we recorded two road kills of the endangered Forest Owlet Athene blewitti and individuals of five other owl species. Among other taxa, road-hits of Jungle Cat, Indian Palm Civet, Golden Jackal, Central Indian Langur, and a few snakes were recorded. Most bird kills on the road were recorded in February while the highest number of mammal and herpetofauna kills were recorded in the month of November. We report that the land use around the road and species trait contribute to vulnerability of a species to road-hit. Based on the frequency of road kills, we have identified seven hotspots of road kills on SH 26. Since road construction is one of the major mandates of the Government in India, it is suggested to carry out systematic environment impact assessment on existing and proposed roads to understand the patterns of spatio-temporal incidents of road kills. Planting of tall trees and installation of speed bumps and signboards to alert drivers should be planned at the initial stage of road construction. If appropriate mitigation measures to prevent wildlife mortalities are incorporated while the road is being constructed, it may be possible to bridge the gap between development and conservation.

This paper deals with two new varieties of Russula species, R. camarophylla var. reticulospora var. nov. and R. aurea var. minuta var. nov. These were collected from the Shiwalik range of northwestern India, in association with Shorea robusta. Russula aurea var. minuta differs from R. aurea in having small sized sporophores, dentate to wavy gill edges with golden or yellow deposition instead of smooth and much smaller spores. Whereas, mushroom R. camarophylla var. reticulospora is close to Russula camarophylla except for the larger carpophores that have white cream pileus surface and larger spores. In basidiospores warts are connected to form mostly complete reticulum instead of mostly isolated warts reported in Russula camarophylla. In view of the presence of some unique varied features in the presently examined collections two new varieties of Russula has been proposed. [ABSTRACT FROM AUTHOR]

This paper pertains to the habitats of the Grey Francolin Francolinus pondicerianus with specific reference to populations, habitat type, vegetation, foraging, impact of human dwellings, and probable threats to populations in 20 villages covering four northern districts of Tamil Nadu, India. A total of 252 individuals were enumerated. During the non-breeding season, birds move in small groups of 2–6. Of four habitats identified, the maximum number of 143 birds was observed foraging in grasslands, while 61 were seen in dry fallow agricultural lands, 37 in dry lakes/canals, and 11 in harvested fields. No significant association was observed between habitat type and bird behaviour. They feed on termites and spilled paddy grains. Males have repeated loud calls and fight with each other. Four species of tall grasses, six of stunted trees and two shrubs were identified to provide bird habitat. Birds preferred to live away from human dwellings, with 193 found 1,000 m away from settlements. The study area continues to be a suitable habitat for Grey Francolin populations, hence this habitat needs protection. [ABSTRACT FROM AUTHOR]

PRIMATES ,RHESUS monkeys ,TRADITIONAL knowledge ,GOVERNMENT agencies - Abstract
Ethnozoological practices to cure various diseases have a long history. Communities that reside near the forest collect wild animals and their derivatives to prepare medicines and get relief from diseases. Northeastern India is home to many tribes with vast traditional ethnobiological knowledge, and there are many reports of zootherapeutic uses in the region. In an attempt to understand primate-based ethnozoologic use in the area a literature survey was carried out using different sources. The findings revealed that Hoolock hoolock was the most used species among the primates (48 %), followed by Macaca assamensis (20 %) and Macaca mulatta (10 %). Among the materials used, the flesh of primates was the most dominant (43 %), followed by the blood (20 %) and brain (14 %). This paper highlights the negative effects of ethno-medicinal uses of primates to draw the attention of conservationists and encourage conservation education to address the damage to primates in the name of health care. Government agencies are also requested to strengthen health care systems to discourage the killing of valuable primate species. [ABSTRACT FROM AUTHOR]

This research paper is an account and analysis of English media reporting on wildlife conservation and protected areas (PAs) in Maharashtra, India, between 1994 and 2015. It is based on 269 articles that first appeared in the media and were then edited for publication in the 'Protected Area Update'. The analysis attempts to draw out significant themes that the media deems important in matters of wildlife conservation. Themes that emerge prominently are related to issues of land, displacement of people, development projects, and tourism. We also discovered that some PAs like the Sanjay Gandhi National Park and the Tadoba-Andhari Tiger Reserve receive disproportionately large media space, while a third of the PAs were not reported on at all. This does not imply that these areas were not reported in the larger media that the newsletter draws upon, but points to the skewed coverage and (limited) importance these PAs get. We argue that media content analysis is a useful tool because the media is the first interface for the general public on issues of wildlife conservation and plays an important role in shaping public opinion. To our knowledge, this is the first such state-wide study of media reporting of wildlife conservation issues; it provides important insights into the wildlife conservation discourse in the country as well as the concerns, priorities, and challenges of the media.

During the field survey in central Western Ghats of India, an interesting dryopteridoid fern species was collected from Nellikathrupodu Range of Billigiri Rangaswamy Temple (BRT) Tiger Reserve of Karnataka. After a critical study of literature, the specimen was identified as Cyrtomium micropterum (Kunze) Ching. In India, this species is known only from its type locality Nilgiri and Palani hills of Tamil Nadu. The present collection from the BRT Tiger Reserve shows its extended distribution and forms the first report for the state of Karnataka. The present paper deals with the assessment and conservation status of Cyrtomium micropterum (Kunze) Ching in India in accordance with IUCN guidelines for the application of Red List Criteria at regional and national Levels, 2012, Version 4.0. Detailed descriptions, photographs, microphotographs are provided for easy identification of this species. [ABSTRACT FROM AUTHOR]

The Environment Impact Assessment (EIA) is a regulatory framework adopted since 1994 in India to evaluate the impact and mitigation measures of projects, however, even after 25 years of adoption, EIAs continue to be of inferior quality with respect to biodiversity documentation and assessment of impacts and their mitigation measures. This questions the credibility of the exercise, as deficient EIAs are habitually used as a basis for project clearances in ecologically sensitive and irreplaceable regions. The authors reiterate this point by analysing impact assessment documents for three projects: the doubling of the National Highway-4A, doubling of the railwayline from Castlerock to Kulem, and laying of a 400-kV transmission line through the Bhagwan Mahavir Wildlife Sanctuary and National Park in the state of Goa. Two of these projects were recently granted 'Wildlife Clearance' during a virtual meeting of the Standing Committee of the National Board of Wildlife (NBWL) without a thorough assessment of the project impacts. Assessment reports for the road and railway expansion were found to be deficient on multiple fronts regarding biodiversity assessment and projected impacts, whereas no impact assessment report was available in the public domain for the 400-kV transmission line project. This paper highlights the biodiversity significance of this protected area complex in the Western Ghats, and highlights the lacunae in biodiversity documentation and inadequacy of mitigation measures in assessment documents for all three diversion projects. The EIA process needs to improve substantially if India is to protect its natural resources and adhere to environmental protection policies and regulations nationally and globally.

The dispersed wetlands in the Darbhanga District of northern Bihar, India, provide a diversity of niches supporting substantial floral and faunal richness. The aquatic macrophytes of a representative range of perennial water bodies were surveyed fortnightly from June to September 2019, supported by a market survey undertaken with local stakeholders. A total of 61 species of vascular macrophytes was recorded, the majority of them Angiosperms (33 species of Dicotyledons from 21 families, and 26 Monocotyledons from 13 families) and two were Pteridophytes. This paper highlights the distribution pattern and potential commercial and medicinal values of aquatic macrophytes found in different wetland systems in northern Bihar. It further stresses their importance for subsistence, medicinal and economic purposes supporting the livelihoods of local people. Current trends and risks contributing to the degradation and loss of this diverse flora and its supporting habitats are considered. We recommend further assessment of the occurrence and values of this botanical resource, and extension of valuation to encompass the diverse additional ecosystem service benefits provided by the region's wetland systems, as a basis for wetland conservation strategies founded on sustainable management and wise use, with particular reference to the potential for enhancing livelihood security of indigenous communities.

We present an updated checklist of marine annelids from the Indian subcontinent. Records of annelid species were obtained from published and grey literatures and online databases. Our review of annelid publications was restricted to the Indian continental shelf region. This paper also discusses the taxonomic status of marine annelid species recorded from this region and problems that impede its research. The updated list comprises of 727 species belonging to 334 genera and 72 families. A total of 152 species have their type locality in India including 88 species that are endemic to the region. The current checklist indicates that 25% (183 species) of the records are questionable and require further examination. Our results highlight that marine annelid richness of the Indian sub-continent is underestimated with many of the native undescribed species being most likely concealed under 'erroneous' or 'cosmopolitan' records. With a combination of factors that include a lack of experts, funding, and failure to update regional literature has resulted in an incomplete state of knowledge for the marine annelid biodiversity from this region. Therefore, there is an urgent need for extensive and intensive sampling to discover new species, conduct detailed re-examinations of doubtful records and, collaborate within the local and international institutes and organizations to improve the regional biodiversity studies.

The Asiatic Lion population has increased in the last three decades, which now occupies a large regional spread with six or more identified satellite populations in eight districts of Gujarat. An overlap of lion habitat with human-dominated landscape elements leads to an increase in lion-human interactions in these growing satellite populations. A high rate of lion mortality has been observed in the periphery of Gir in the last decade due to falls into open dug wells. These wells have been excavated for irrigation in the agricultural landscape of Gir. About 145 wild animals including lions have died due to accidental falls into open wells in past 10 years. It has been observed that construction of parapet walls around wells in some of the peripheral areas of Gir Sanctuary have prevented this accidental mortality at very low cost. To assess the efficiency of these measures we did a survey of 20 random villages in the Gir Lion Landscape to collect data on the types of wells that cause this uncalled-for mortality. The paper explores the reasons for the lions falling into wells in the agricultural areas outside the Gir Sanctuary. The survey has shown that the corridors used by lions and in the satellite population areas are high risk sites where more parapet walls should be built on a priority basis. From the year 2007 to 2018 more than 48,000 parapet walls have already been randomly built in the periphery of the Gir Sanctuary. Out of 130 identified wells, 90 were protected with parapet wall or iron net while, 32 were without parapet wall and rest eight were with unfinished parapet wall. Providing a scheme for building more parapet walls around prioritized open wells would be an effective step towards Asiatic Lion conservation in the Gir Lion Landscape. Our survey indicates that there has been no mortality of lions in those wells where parapet walls have been built. [ABSTRACT FROM AUTHOR]

Octocorallia (Cnidaria, Anthozoa) comprising over 3,600 nominal species within three orders, Alcyonacea, Helioporacea and Pennatulacea, is one of the most poorly known groups of marine invertebrates. Half of known octocoral species occur in the Indo- Pacific, but not much is understood about research efforts and outputs in this region, particularly in the Asian context. A review of the literature on Asian octocorals during a 40-year period from 1978 to 2018 revealed that most research was concentrated in particular regions/countries. An analysis of research originating from India indicated several issues, including low quality data and local taxonomic impediment. This paper examines the general trends and geographic disparity in Asian octocoral research over the past four decades, analyses the extent and source of such disparity by drawing parallels between India and the rest of Asia, and provides recommendations for improving octocoral studies in the region.

The study was carried out in Nauradehi Wildlife Sanctuary, central India. The forest is classified as a tropical dry deciduous type, with teak Tectona grandis as the predominant species. Extensive field trips were carried out during 2018-2020 to document the medicinally important tree species. The medicinal importance of these plants was recorded through interviews, group discussions with local tribal communities and on the basis of the literature available. Enumeration of tree species in this area showed occurrence of 50 tree species belonging to 37 genera and 21 families. The study further observed that several species were being used as traditional medicine by the local tribal folks, traditional healers in the study area, and also by pharmaceutical industries. The study observed that some species in the sanctuary were rare due to several developmental projects, forest destruction, and over-exploitation. The study provides details about the botanical identity, family, local name, plant parts utilised and uses for treatment of diseases. The present paper identified the tree species for their conservation status and accordingly recommends the priority for their conservation in the study area. We recommend that tree species documentation might be helpful for drug formulation and the preservation of traditional knowledge. [ABSTRACT FROM AUTHOR]

The examination of a large number of herbarium specimens combined with field observations reveal that Ficus palmata Forssk. subsp. palmata does not occur in India. The Indian plants occurring in the wild from the north-west to the south belong to F. palmata Forssk. subsp. virgata (Roxb.) Browicz. The maximum concentration of the taxon lies in northernIndia extending up to about 2200m altitude in the Himalaya. In southern India, the taxon is reported only in Andhra Pradesh. F. palmata subsp. virgata is notoriously variable in its entire range of distribution in almost all morphological characters. The variations are continuous and its two extreme forms, with entire leaves and lobed leaves, are connected with numerous intermediate forms. The taxon is closely allied to F. carica L., which is distributed from the Mediterranean region to Afghanistan and occurs only in cultivation in some parts of India. The paper also explains the relationship of the taxon with its closely allied species and provides a key to discriminate among them. In this paper, the taxon is described, illustrated with colour photographs and line drawings and provided with a distribution map. [ABSTRACT FROM AUTHOR]

Watershed avifaunal inventories are useful in devising management strategies appropriate to the habitat, as well as species conservation. The Chenab River basin forms one of the largest and most important river basins in Jammu & Kashmir. The upper Chenab catchment offers a rich and diverse fauna, especially birds, owing to variety of habitats, different climatic regimes, and a wide range of altitude,. We present an avifaunal list of four watersheds--Bhot, Marusudar, Kalnai and Neeru of the Chenab River basin including Kishtwar Town and the surrounding area of the upper Chenab catchment over an elevation range of 820-4,500 m. The list includes 251 species belonging to 60 families and 150 genera of which six are globally threatened, 127 residents, 124 migrants and three new to the state. The paper also describes species-wise habitat occupancy, feeding behaviour, migratory status and abundance of the avifauna. The study reveals that mosaic habitats comprising forests, riverbeds, rangelands and rocky outcrops are crucial for the conservation of birds in the region. [ABSTRACT FROM AUTHOR]

This paper presents the spatial and temporal variation in the diversity of malacofauna in relation to the water chemistry of the Aripal stream of Kashmir Himalaya. A total of 12 species were reported which belong to four families, Lymnaeidae, Physidae, Planorbidae, and Bithyniidae from class Gastropoda, and two families, Cyrenidae and Pisidiidae from class Bivalvia. The family Planorbidae contributed 34% to the total annual molluscan population followed by Lymnaeidae (28%) and Bithyniidae (18%). During the collection, Gyraulus sp., Planorbis sp., and Bithynia tentaculata were prevalent at all sites, with predominance of Bithynia tentaculata. Species richness and abundance were observed maximum at site A3 (down-stream) and minimum at site Al (up-stream) while in the case of temporal variation, species richness and abundance were maximum in summer and minimum in winter. Shannon-Wiener index, Simpson index, Margalef index, and Pielou evenness index were used to calculate the diversity, dominance, richness, and evenness of molluscan species, respectively. Physico-chemical parameters revealed a non-significant spatial variation (P >0.05) except pH, total hardness, and alkalinity while a significant temporal variation (P <0.05) was observed in the physico-chemical parameters except dissolved oxygen. A significant positive correlation was seen between the molluscan species and total hardness. In the present study, the stone mining, channel morphology of stream, habitat heterogeneity, and physico-chemical parameters were also found to promote the spatial and temporal diversity of malacofauna.

Identification and mapping of the spatial distribution of species is an important aspect of zoogeographical enquiry. The habitats of many species are facing the threat of depletion in increasingly human-influenced environments. This has already led to the extinction of many species in different localities, making understanding the linkages between anthropogenic threats and species distribution of utmost importance. A GIS-based model was applied to gain an overall picture of the potential distribution of Ploceus philippinus (Baya Weaver) in and around Nagaon District in Assam. The used maxent model in the GIS environment gives a highly significant Area Under Curve (AUC) validation statistic of 0.99. Out of the total area of 3,975 km2, 596.86 km2 (15%) is demarcated as a high-potential area. Such predictions are highly useful in assisting in the conservation of threatened species under current and future climatic conditions. [ABSTRACT FROM AUTHOR]

This communication reports the repeated sighting records of the Amur Falcon Falco amurensis with photographic evidence in the D'Ering Memorial Wildlife Sanctuary (DEMWS) of Arunachal Pradesh during the summer. Though there are many sighting reports of the Amur Falcon from many places in India, all are onward journeys (October and November). Hence, not only the repeated sighting of the Amur Falcon but also its sighting during the month of May in DEMWS is the record of its kind. This is significant information for ornithologists, as the recent sighting in the sanctuary is the second record of this raptor during the summer in the state, which also demonstrated that DEMWS is a significant flyway and a preferred stopover or refuelling site during the return migration of this raptor towards their breeding grounds.

Management of wildlife depends mostly on scientific data; ignoring this can lead to unintended consequences. We take the case study of the wild male Asian Elephant Rivaldo of the Sigur Region, who was translocated out of his range. Rivaldo returned to his home range within a few days, which could have been expected if scientific publications had been consulted. We suggest that a simple checklist of relevant publications can help park managers to decide on a proper management procedure. We also used a simple Bayesian framework to visually show how the probability of predicting a management outcome is increased by prior knowledge. The expensive and risky effort to relocate the elephant could have been avoided altogether if prior knowledge had been taken into consideration. [ABSTRACT FROM AUTHOR]

Our paper deals with the diversity of the scorpion fauna of Saswad-Jejuri region in western India, and highlights the conservation implications of quantitative studies. Eight species of scorpions from five genera and three families are recorded in 10 microhabitats. Some of these areas are categorized as 'wastelands' and hence are vulnerable for land use modifications. The interdependence of such microhabitats and their neglected inhabitants like scorpions is highlighted in this study. This information provides a baseline biological data for further demographic and ecological studies and stresses the need for impact assessment prior to undertaking developmental projects in 'wastelands', since arachnids exhibit restricted movements and are vulnerable to habitat modification.

Ophiorrhiza caudata is a creeping, perennial herb distributed along wet and shady areas. The species is distylous with two distinct floral morphs: pin and thrum. Flowering usually occurs during the monsoon season. No particular difference was noticed in the flowering phenology of the two morphs. Presently the species is self-incompatible, however, it shows a tendency towards intramorph compatibility. Fruit set is above 60% in open pollination and intermorph pollination. Bees and butterflies are the major pollinators. The pollen flow between the two floral morphs varies depending upon floral morphology and pollinators. Fruit is a bi-valved capsule which dehisces by a splashing drop mechanism. The seeds are very minute. The rate of seed germination and seedling establishment in the wild condition is very poor due to adverse climatic factors. Ophiorrhiza caudata is struggling for survival in its natural habitat, where habitat fragmentation, climatic factors and poor seedling establishment could account for its narrow distribution.
