Abstract: A study on lichens of Mizoram enumerating 118 Species belonging to 37 genera and 17 families are provided. 10 (Ten) species viz. Bacidia connexula, Buellia curtisii, Caloplaca citrina, Herpothallon philippinum, Leptogium delavayi, Pertusaria pertusa, Pertusaria pseudococcodes, Pyrenula andina, Trichothelium epiphyllum and Usnea nipparensis are reported for the first time in Mizoram. Mizoram is poorly explored in study of lichens among different states of India. The region is experiencing a lot of anthropogenic problems like shifting cultivation, expansion of agriculture, introduction of plantation crops, destruction of natural forest, collection of wood, infrastructure development and road construction as a result the valuable resources lichens are lost. This study will lead to further research on Lichens and contribute to a better knowledge of their distribution in this ecologically biodiversity state of Mizoram.

Abstract: Live adult male specimens of Macromia moorei Selys, 1874 of family Macromiidae have been collected from Andretta, Himachal Pradesh (India). Male germ cell chromosomes of the species have been described on the basis of conventional staining, C-banding, silver nitrate staining and sequence specific staining. The species possesses 2n (♂) =25m, as the chromosome number and XO (♂)/XX (♀) type sex determination. Dark terminal C-bands are present on all the autosomal bivalents, while m bivalent shows small terminal C-bands and X chromosome is C-positive throughout the length. Terminal light/dark NOR’s are present on all autosomal bivalents including m bivalent, while X chromosome also possesses terminal NOR. During sequence specific staining, all the autosomal bivalents show prominant terminal DAPI and CMA3 bright regions, while m bivalent possesses less bright DAPI and CMA3 signals and X chromosome possesses both DAPI and CMA3 regions. Linear characterization of chromosomes of Macromia moorei has been done for the first time.

Abstract: Purpose: The purpose of the study was to assess the impact of perceived crisis support (PCS) and perceived organization ethics (POE) on affective organizational commitment (AOC) of medical practitioners and to explore the mediators involved in these causal relationships. Three factors were considered as mediators which were general mood (GM), job satisfaction (JS) and knowledge sharing (KS).

Design/methodology/approach: It was an empirical research and data was collected through survey technique from 659 medical practitioners working at Indian hospitals. Structural equation modeling using SPSS Amos software version 20 was used to test the hypothesized model.

Findings: All mediators’ partially mediated in the causal relationships. It was found that the direct relationship of PCS with AOC was stronger in comparison to POE with AOC. KS was found to be the strongest mediator.

Research limitations: The limitations of the study were that it used self-reported cross-sectional data and excluded the demographic factors. The reliability of measures for POE, GM and JS was low.

Practical implications: Management will focus on humanizing hospitals for increasing AOC of medical practitioners. This will help to retain talent for increasing their competitive edge.

Originality/value: For the first time, the paper explores the significance of POE and PCS for building AOC among medical practitioners in developing country. An emotional component general mood is included as mediator. KS was examined as mediator that was till date considered an outcome of AOC.

Abstract: This paper is a review of the state of nature conservation in Nigeria, and the measures adopted for the protection of the wildlife. The major problems bush burning of wildlife habitat, overgrazing of local animals, environment predation, over hunting, poaching and. lack of tourism and accommodation. Steps taken so far to protect wildlife include declaration of priority sector at the national level for which funds should be earmarked, establishment of single agency to deal with all matters covered by the Convention. Certain species have been designated to be totally protected, and others may be hunted or captured only under special authorization, encouraging people to take up afforestation and conservation in new areas. It is suggested that more national parks and conservation areas and existing ones should be maintained. Government should give more room for private sector to establish private conserving centers for sustainability of wildlife. There should be proper planning like the entrenchment of good game management which will sustain the present yields or maintain the intrinsic quality of forests and its resources. The problems and challenges facing the sustainable of wildlife conservation and management in Nigeria could be eradicated if local, state and national bodies join hands together to work as a single body and set up Forest Commission to look into restructuring, reform and strengthening the entire forest set up and affiliated institutions in the country. Promotion and encouragement of research related to conservation, management and the rational use of natural resources particular to ecological and sociological factors should be taken to practice to optimize wildlife activities in Nigeria.

Abstract: Environmental stability and cleanliness are of paramount importance for the existence of life. Slight changes in the environmental conditions of any ecosystem reflect the impact on the living organisms. Various anthropogenic activities are mainly responsible for the deterioration of environmental quality. In developing countries, the rapid industrialization with the resultant urbanization and the unplanned and excessive exploitation of natural resources are the major causes for pollution problem in cities and towns. According to Smith (1977), every human waste product which when ingested into the biosphere, affects the normal functioning of ecosystem and has adverse effects on animals and humans. Water is one of the most important and fundamental natural environmental resources and basic component of the ecosystem. It is the basic need of every living organism. The need of the hour is that the quality as well as the quantity of these vital resources should be maintained. But we are lacking in this effort because billions of gallons of waste water from cities, housing settlements, industries and agricultural fields are thrown into water courses to such an extent that 70% of streams and rive5rs of India contain polluted water (Rastogi and Jayaraj, 1987).

Keywords: waste water, natural resources, environmental resources, industries, agricultural fields.

Abstract: Catharanthus roseus (L.) G. Don widely known medicinal herb, belongs to Apocynaceae family has been cultivated for its wide range of therapeutic values. Arbuscular mycorrhizae (AM) are helpful symbionts for growth of the plant and its development, offering a possible substitute for high input agricultural technology employed for production of environmentally hazardous fertilizers. Therefore, the present investigation was focused on to analyze the effect of AM fungi (Acaulospora laevis and Glomus mosseae) along with Pseudomonas fluorescens, alone and in combinations, on different growth parameters of Catharanthus roseus in a pot experiment with autoclaved sterilized soil under polyhouse condition. AM inoculum and P. fluorescens showed significant increase in different growth parameters after 120 days of inoculation.  Among all treatments, consortium of G. mosseae, A. laevis plus P. fluorescens was most effective for increased shoot height, root length, leaf area, shoot and root biomass, percent root colonization and AM spore number. Moreover, chlorophyll content, phosphorous and phosphatase activities were found to be maximum when AM fungi and P. fluorescens were applied in consortium.

Keywords: Glomus mosseae, Pseudomonas fluorescens, Catharanthus roseus, Leaf area, Phosphatase activities.

Abstract: Bacillus Thuringiensis Kurstaki (Btk) is widely used as an insecticide which is effective against lepidopterans, but is it safe for animals to ingest? What consequence does it have on animal blood? Through my research I had the desire to find the answers to these questions, which is why I exposed numerous sheep blood samples inoculated with Btk at different fixed temperatures. Once exposed to these temperatures, I observed the visual characteristics of the blood samples and used microscopy to view past what the naked eye could see. My findings to this research returned quite fascinating results which could question whether the use of Bacillus Thuringiensis Kurstaki is a safe choice of insecticide if used on plants and crops which are intended for animal consumption. Although the Bacilli bacterium does not directly implicate the function of blood, it does introduce the presence of micro-organisms too large to be bacterial which can have a negative impact on the blood function.

Abstract: Eighteen microsatellite loci were analyzed in 80 random individuals to characterize the genetic variability of two domestic goat breeds found in Sudan: Nubian goat, Nilotic goat. Heterozygosity, Allele diversity, polymorphism information, F-statistics, unintended estimates of gene flow (Nm) and Nei’s standard distances were measured. Based on the estimated mean heterozygosity, the lowest genetic diversity was confirmed in Nubian goat (HE=0.381), and the highest in Nilotic goat (HE=0.669). After corrections for multiple significance tests, deviations from Hardy-Weinberg equilibrium were statistically significant overall populations and loci, reflecting the deficiencies of heterozygotes (global FIS=0.053). Based on pairwise FST and Nm between different breeds, there was no genetic differentiation between a Nubian goat and Nilotic goat, indicating that these breeds have been genetically subdivided. Likewise, individual clustering based on the proportion of shared alleles showed that Nubian goat individuals formed a single cluster separated from the other Nilotic goat breeds.

Abstract: High level of uric acid was found in the haemolymph of the sixth instar larva of the moth, Orthaga exvinacea Hampson. The uric acid level was found to be varying from 3.8 µmole/ml to 5.59 µmole/ml in the unit volume of haemolymph. In the total volume of haemolymph, the uric acid concentration was varying from 0.08 µmole/total tissue to 0.20 µmole/total tissue during sixth instar development. It is suggested that uric acid is playing an important role in the maintenance of the homeostatic equilibrium of the internal environment of the insect larva.
