Abstract

The study on status and distribution of gaur was carried out in Trishna Wildlife Sanctuary (TWS), Tripura between 2002 and 2004. The density of gaur was found to be 1.5 groups per km² and 5.9 individuals per km². The group size of gaur ranged between 2 and 14 and the observed overall sex ratio (Bulls : Cow) was 58 : 100. Gaur density in TWS remained without any significant change and thus showed that the population is not facing any immediate threat, if not removed directly by poaching, hunting or epidemics. Group size and sex ratio of gaur observed in TWS is comparable with any of the population so far reported from India and thus can be seen as a potential population for the long term conservation.

Abstract

Tiger crisis is a stark reality of our times. There is deep concern about but its implications are not fully and properly recognized. Conserving the tiger is to conserve the biodiversity and consequently nature itself, so very essential for our own existence. Development poses a great problem as it is diametrically opposed to conservation, in essence craze for tangible benefits vis-it-vis intangible benefits goes against objectives of conservation. Development of scheduled tribes living in and around forests, upto developed nation standards will further tax our limited resources to the detriment of Homo sapiens. The authors suggest levying a tax on hotel industry, earning from eco-tourism, to provide funds for the welfare of ecosystem people. Stringent measures should be taken to curb poaching, illicit trade in wildlife and its production, revamp the monitoring system by inducting scientifically trained person in the forest services etc. and bring back the lost glory.

Abstract

Development of Melampsora leaf rust in Populus ciliata reveals that clones, which were disease free during July, got infected in the month of August. Clone Kufri has least disease while Theog was most susceptible. Disease development was rapid between July and August months. PCM 5195, 5011, 5180 and 5157 hybrids of P. ciliata x P. maximowiczii had least disease while PCM 5084 and 5053 were highly susceptible. The development of disease was negatively
correlated with temperature but positively with relative humidity and rainfall.

Abstract

Variation in the dimensions of urediniopustules and urediniospores of Melampsora ciliata produced on different popular species/cultivars/clones/hybrids has been observed in the present investigations. Smallest urediniopustules were produced on P.deltoides 'Lux' (0.38 mm) while largest on P.yunnanensis (1.34 mm). In P.ciliata clones/hybrids, smallest urediniopustules were recorded in 53M1 (0.16 mm) while largest in Chhatrari (0.90 mm). Largest spore size (33.6 × 16.3 μm) was recorded on P.deltoides 'Lux' and 64M1 (36.3 × 17.3 μm) while smallest on P. xeuramericana 'Robusta AE' and 53M1. Irrespective of species/cultivars, urediniospore size ranged from 13.1-39.3 × 13.1- 19.6 μm. The average urediniospore size of M.ciliata produced on P.ciliata clones ranged from 30.8 -36.3 × 15.4 - 17.1 μm while that on hybrids from 27.2 - 36.3 × 14.5 - 20.0 μm.

Abstract

Tripura is smallest of the seven North-Eastern States, but because of her unique Bio-geographical and Zoo-geographical position, is very rich in bio-diversity and biological resources. Over the past few decades, however, various factors have adversely contributed towards wildlife conservation and management in the State. The paper records some of the unique faunal components of wildlife in the State and discusses about likely steps for sustainable wildlife conservation vis-a-vis meeting varied needs from diverse user groups.

Abstract

There are no records of presence of naturally occurring wild population of Golden Langurs (Presbytis geei, Khajuria) in Tripura. Therefore, their operation for release in Wildlife Sanctuaries in the State has been suggested for captivity.

Abstract

The present investigations deal with the throughfall, stemflow and intercreption loss in Cedius deodara Loudon plantation (94.5% crown density) or about 35 years age at Shillaroo, Kolgarh Forest Division, Distt. Simla (Himachal Pradesh). Of the total rainfall (1850.1 mm) 2.9% (55.3 mm) stemflow, 71.8% (1328.5 mm) throughfall and 25.2% (466.2 mm) interception loss were recorded respectively by for the whole study period. The minimum interception loss (18.7%) was observed in the month of July, 1980 which had the maximum (370.2 mm) rainfall. The highest interception (69.1%) was recorded in the month of February, 1980. which had the lowest (7.0 mm) rainfall. Interception loss was decreased with the increasing amount of precipitation.

Abstract

A fresh study of the suitablity of Melia azedarach for pulp and paper has shown that it is a very promising raw material for wrapping, writing aDd printing paper provided the trees are grown not too fast. Very fast grown material is characterised by very low specific gravity and wide fibres with large lumen. These fibres collapse due to their thin walls during the course of sheet formation resulting in poor strength properties. The earlier reports on its unsuitability were apparently based on tests carried out on very fast grown material.

Abstract

The present paper describes ethnomedicinal plant of Deoband tehsil of Saharanpur district, Uttar Pradesh. An ethnobotanical survey was conducted in villages of study area, during 2005-2006.74 plant species under 69 genera belonging to 42 families were found of ethnomedicinal value. The plant species are enumerated in alphabetical order with families and local names, followed by their ethnomedicinal uses.
