(Fig. 1). It is hilly and mountainous with deep gorges and steep slopes bordering narrow valleys (Fig. 2-14), and has a geographical area of 16,579,00 ha. The state consists of a narrow strip of hilly area running from the northeast to the southwest, which is located in the northern extension of the Arakan Yoma ranges of Myanmar. It comprises of the erstwhile Naga Hills district of Assam and Tuensang Frontier Division of the North East Frontier Agency. Nagaland got its statehood as the 16th state of India on pt December, 1963. For Administrative convenience, the state is divided into 11 districts (11 districts are offici~lly declared, but a map to this effect was not available) namely Peren, Dimapur, Kohima, Phek, Kiphire, Zunheboto, Wokha, Tuensang, Mokokchung, Longleng and Mon. Kohima, the capital, at 1495 m above mean sea level is historically a very important city. The war cemetery here stands as a monument of World Peace. N agaland is home to 16 major tribes. The state claims to have a literacy rate of 67 % and the population density is 120 persons per sq. km. With its exquisitely picturesque landscapes, vibrant colourful sunrise and sunsets, lush and verdant flora (Fig. 2-14), Nagaland is a land that represents unimaginable beauty molded perfectly for a breathtaking experience. It is sometimes referred to as the Switzerland of the East. Nagaland is bounded by Assam in the west, Myanmar on the east, Arunachal Pradesh and parts of Assam in the north and Manipur in the south. The forest types are Tropical Wet Evergreen, Tropical Moist Deciduous, Montane Wet Temperate and Subtropical Pine Forests. The recorded Forest Area in N agaland is 8,629,00 ha which is 52% of the geographical area of the state and 1.1 % of India's forest area. An area of 88.36% of the recorded forest area is under private control and the rest under state government. Tropical Wet Evergreen forest occurs in patches in the lower and middle elevations all over the state, except in the southwest where Tropical Moist Deciduous forests dominate. l\1any of the river valleys and gorges are covered with Evergreen forest. The tropical semi-evergreen forest also occurs in many of the once evergreen forests. In the higher hills Subtropical Broadleaf forest occurs with small areas of conifers in the eastern parts. There is no large Grassland in Nagaland, however, small patches occur in sheltered valleys and along the rivers. In the abandoned Jhum, grasses appear till they are replaced by shrubs and trees. As per the Forest Survey of India Report, 1999, there has been an overall increase in the dense forest cover in Nagaland because of improved land 2 Ree. zoo/. Surv. India, Oee. Paper No. 285 management. The state has one National Park and three Wildlife Sanctuaries. The climate is tropical 'monsoon' type with a hot wet summer and a cool dry winter. Altitude varies from 194 m to 3841 m and the temperature generally ranges from less than 0° to 35°C. Annual rainfall averages between 1800 to 2500 mm. Some of the rivers of the state wherein collections were made during the surveys are Chathe (also known as 'pagla nadi', because of the flash floods occurring in it), Dhansiri, Kaleiru, Munglai, Mutsure, Nhezu, Saprai, Sedzu, Tanghairoi, Taphi, Tiru, Tathan, Tening and Zingkhi (Fig. 2-14). Nagaland exhibits twin drainage systems. Its western and northern parts are drained by Brahmaputra drainage, while eastern and southern part by Chindwin drainage. Studies on the Fish fauna of the state have been undertaken by Hora (1921, 21a, 36); Hora and Mukherjee (1935); Malhotra and Suri (1969); Sen, (1985); Talwar and Jhingran (1991); Nath and Dey (1997); Kosygin and Viswanath (1998); Jayaram (1999); Menon (1999); Sen (2003) and Karmakar and Das (2005). As per literature 125 species of fish have so far been reported from the state. The present study has enhanced knowledge of this group and a total of 140 species, including 15 new records, have been reported herein. All the reported and recorded species have been incorporated to get an overall picture of the fish resources of the state. The systematic arrangement is as per J ayaram (1999) and the nomenclatural status as per online version of Eschmeyer (2007, www.fish~ase.org). Status of the species wherever applicable has been mentioned under remarks as per BCPP, C.A.M.P. (1999). For all the species only original references have been cited. The species marked with** denotes new record for the state. Apart from Chanda's (1994, 2002) comprehensive work on the amphibians, there is very little information on the amphibian fauna of Nagaland (Ao, et al., 2003; Kiyasetuo and Khare, 1986). The present paper deals with 43 species of amphibians. Status of the species has been mentioned under Remarks wherever applicable is as per BCPP, C.A.M.P. (1998). Located in the 'Biodiversity hot spot' region, Nagaland is very rich in herpetofauna. However, the state needs yet to be thoroughly explored to assess its herpetological resources. Ao et al. (2004) reported 41 species of reptiles from N agaland with 19 new records for the state. Subsequently, Mathew (2005) added two more species. Fauna of Nagaland (2006) reported 62 species of reptiles. The present study reports 74 species of reptiles. I MON r J: t o) . w ~ Q -' / : -... () WOKHA ZUNHEIBOTO ; - « / ) KIPHIRE . - ( J;- -.... /' - KOHIMA PEIREN · - -'".-' I MA N IPU IR I ~ ig.

J Morphol Sci 2018;35:142–152. Abstract Introduction Water pH affects the breeding, hatching, development, locomotion, mortality and habitat distributions of species in nature. The external gills of anuran tadpoles were studied by several authors in relation to abiotic factors. Exposure to low and high pH has been found to adversely affect the different tissues of various organisms. On that consideration, the present investigation was performed with tadpoles of the species Hyla annectans and Euphlyctis cyanophlyctis. Material and Methods The maximum and the minimum pH thresholds were determined prior to the detailed experiments on the effects of pH. The pH that demonstrated 50% mortality was taken as the minimum and maximum pH thresholds. The hatchlings of both the species were then subjected to different pH (based on the minimum and maximum pH thresholds). After 48 hours of exposure, the external gills of the hatchlings were anesthetized and observed under a scanning electron microscope. Keywords Results After 48 hours, clumping, overlapping and curling of the secondary filaments ► Hyla annectans of the external gills and epithelial lesions in response to both acidic and alkaline pH ► Euphlyctis were observed.

There was no previous report on piscine diversity of this river in Assam. Survey was conducted in the lower stretch of the river in Goalpara district from April 2018 to March 2019. Fish specimens were collected from five pre-selected sites, preserved and identified adopting standard methods. A total of 74 fish species belonging to nine (9) orders, 26 families and 58 genera were recorded. Cypriniformes was the dominant order with 35 species followed by Siluriformes with 19 species. IUCN status shows two vulnerable, eight near threatened and 66 species under the least concern category. Prevalence of anthropogenic threats like garbage dispersal and agricultural pesticide flow to the river, setting of brick industries on the bank, poison fishing in the upper stretch etc. may affect the fish population in this river. In this regard, awareness is the need of the hour among the inhabitants of the surrounding villages. Keywords: Ichthyofauna, Jinari River, Goalpara, Brahmaputra River, Assam INTRODUCTION The Northeastern region of India is considered to be one of the hotspots of freshwater fish biodiversity in the world (Ramanujam et al., 2010).

  • Anuran Diversity Distribution Patterns in Lower Dibang Valley of Arunachal Pradesh, India
    Herpetology Notes, volume 11: 781-789 (2018) (published online on 27 September 2018) Anuran diversity distribution patterns in Lower Dibang Valley of Arunachal Pradesh, India Jayanta K. Roy1,2*, Ramie H. Begum1, and M. Firoz Ahmed2 Abstract. The present study was conducted to estimate the anuran species diversity distribution patterns at Lower Dibang Valley with respect to secondary habitat conservation. Time-constrained Visual Encounter Surveys (VES) were conducted for amphibians followed with opportunistic observations during the study period. We compared the species diversity from three land use/land cover types that explained the available habitats and the importance of secondary forest in recolonizing anuran species during the course of study. Interestingly, anuran diversity measured from secondary/abandoned jhum and primary forest areas were found to be relatively equal (Shannon index; H: 2.77 and 2.76). The highest percentage of unique species was recorded from primary forest followed by secondary/abundant jhum and agriculture/settlement areas. However, secondary/abandoned jhum areas provided refuge for most anuran species normally inhabiting primary forest. We found beneficial human interaction along with secondary succession for creating habitat heterogeneity in secondary/abundant forest; and thus supports maximum anuran breeding habitats and species diversity in secondary/abundant jhum areas. Hence, secondary/abundant habitats were also important for anuran habitat conservation along with primary forest. We reported four new distribution records from Arunachal Pradesh: Nanorana chayuensis, Hydrophylax leptoglossa, Odorrana chloronota and Theloderma moloch. Keywords. Arunachal Pradesh, anuran diversity, habitat heterogeneity, land use/land cover, Lower Dibang Valley Introduction et al., 2005), followed by vegetation cover and local microclimate (Rios-Lopez and Aide, 2007).

  • Terrestrial Protected Areas and Managed Reaches Conserve Threatened Freshwater Fish in Uttarakhand, India
    PARKS www.iucn.org/parks parksjournal.com 2015 Vol 21.1 89 TERRESTRIAL PROTECTED AREAS AND MANAGED REACHES CONSERVE THREATENED FRESHWATER FISH IN UTTARAKHAND, INDIA Nishikant Gupta1*, K. Sivakumar2, Vinod B. Mathur2 and Michael A. Chadwick1 *Corresponding author: [email protected] 1. Department of Geography, King’s College London, UK 2. Wildlife Institute of India, Dehradun, India ABSTRACT Terrestrial protected areas and river reaches managed by local stakeholders can act as management tools for biodiversity conservation. These areas have the potential to safeguard fish species from stressors such as over-fishing, habitat degradation and fragmentation, and pollution. To test this idea, we conducted an evaluation of the potential for managed and unmanaged river reaches, to conserve threatened freshwater fish species. The evaluation involved sampling fish diversity at 62 sites in major rivers in Uttarakhand, India (Kosi, Ramganga and Khoh rivers) both within protected (i.e. sites within Corbett and Rajaji Tiger Reserves and within managed reaches), and unprotected areas (i.e. sites outside tiger reserves and outside managed reaches). In total, 35 fish species were collected from all sites, including two mahseer (Tor) species. Protected areas had larger individual fish when compared to individuals collected outside of protected areas. Among all sites, lower levels of habitat degradation were found inside protected areas. Non -protected sites showed higher impacts to water quality (mean threat score: 4.3/5.0), illegal fishing (4.3/5.0), diversion of water flows (4.5/5.0), clearing of riparian vegetation (3.8/5.0), and sand and boulder mining (4.0/5.0) than in protected sites.
