Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. Cryopreservation is a process where biological materials such as cells and tissues are preserved by cooling to very low temperatures, usually at -196°C (the temperature of liquid nitrogen), yet remain viable after later warming to temperatures above 0°C. Plausible future birth rates lower than the expected rates lead to much zone due to reduced water current and higher transparency. Share to Twitter Share to Facebook Share to Pinterest. The present research investigated morphology and production character in ten accessions of local eggplant. The structural components of an ecosystem are the vegetation, water, soil, atmosphere, and biota (plant and animal life of a region, habitat, or period) and their interactions within and across the ecosystem(s). can support a more productive fishery. The search for sustainable economic growth and development in Ghana commenced in 1957 when the country gained independence. The DMSO proved better than glycerol. Introduction The term Biodiversity was first coined by Walter G. Rosen in 1986. /Type /XObject A number of different protocols are advocated in literature for the preservation of fish semen but most of them are concerned with the salmonids, tilapia, and carp. Orchid species were able to create specific microclimates that can accommodate the diversity of flora and other organisms. With little recognition of contribution of local knowledge in biodiversity conservation, the current paper reviewed the potential of available indigenous knowledge in Tanzania and challenges limiting adoption of this vital knowledge on rangeland’s biodiversity conservation. In this paper, a broad literature search was conducted to identify relevant articles that correspond to the main topic. response of each river to dam differs. Organisms depend on it for the air to breathe, the The term, biodiversity, is given to determine all the variety of life that is on Earth. Some of the existing measures of biodiversity conservation include; reforestation, zoological gardens, botanical gardens, national parks, biosphere reserves, germplasm banks and adoption of breeding techniques, tissue culture techniques, social forestry to minimize stress on the exploitation of forest resources. Schizothorax richardsonii is an indigenous snow-trout of Garhwal Himalayas, showing continuously decreasing trend in the capture fishery of the region since past few years.

The most unique feature of Earth is the existence of life, and the most extraordinary feature of life is its diversity. Vanilla planifoliawas known to have the highest density of 110, while the highest frequency were Acriopsisliliifolia, Dendrobiumcrumenatum, and Vanilla planifolia, which is 0.7. The fresh and non-contaminated semen always showed more than 75 percent motile sperm. Principal component analysis (PCA) indicated that four components (PC1 to PC4) accounted for about 90% of the total variation among traits in eggplant accession. The physico-chemical characteristics recorded during the study period in the different seasons are water temperature (9.0-16.0 0C), velocity (.50 m-s-1.46 m-s), TDS (49 mg-l – 65 mg-l), pH (8.0 - 8.3), DO (7.3 mg-l – 10.5 mg-l), Free CO2 (0.10 mg-l – 0.30 mg-l) and turbidity (06-30 NTU). A positive correlation between spermatocrit value and sperm density was established (r=0.836, P<0.001). The colour (creamy white), pH (7.34 ±0.05), sperm density (8.67, Most of the riverine resources in Garhwal region are mountainous and perennial either snow fed or spring originated. Animal diversity assessment technique describes impact of pollution on their environment. However, the word “Biodiversity” is relatively new, and is thought to have first been coined as a contraction of the term “biological diversity” in 1985 and then popularised by a number of authors1. Recent advances in chemical applications in the agricultural sector have been contributed to disruptive contamination of crop and environment. Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form.

Among of the challenges hindering the adoption and involvement of indigenous knowledge to conservation are; scientific bias toward pastoral communities, loss of local expertise, poor knowledge inheritance systems, poverty, conflicts and emergence of pandemic diseases. The biodiversity in Ghana is very rich. functioning and healthy. All these mountainous streams provide a good natural habitat for survival of hill stream fishes. food to eat, and the water to drink. /SA true stream Equilibration time was standardized as 45 min for DMSO and 60 min for glycerol. Biodiversity is the variety and variation in different forms of life on earth, including the Soon after, first report on fish sperm cryopreservation was published by Blaxter (1953) and since then semen of over 200 freshwater and marine fish species have been cryopreserved. ... More than 12,000 years ago since agriculture began, roughly 7,000 plant species have been used for human consumption. The 0.5 ml French medium straws were used to store the milt in liquid nitrogen. India is one of the most diverse nations in the world. Biodiversity 552244. Advantage of cryopreserving the fish semen is well established. including promoting the aesthetic value of the natural environment, contribution to our material well-being through utilitarian values by providing food, fodder, fuel, timber and medicine. Methods for surveying and monitoring fauna will depend on the types of fauna that the study is looking for. One major contribution that the social sciences can make about the uncertain human future is to help us explore alternative futures; for example, what would the world be like with depleted biodiversity, or with higher global temperatures than average. Various cooling method has been successfully used to cryopreserve the fish sperm. >> The importance of biodiversity, especially of the readily useful agricultural biodiversity, and its use for the sustained future of humans, requires wider understanding by the general public; it needs to be routinely turned into actions like diversity of foods and other everyday uses. 4.4 BIODIVERSITY AT GLOBAL, NATIONAL AND LOCAL LEVELS 88 4.5 INDIA AS A MEGA DIVERSITY NATION 89 4.6 HOTSPOTS OF BIODIVERSITY 90 4.7 THREATS TO BIODIVERSITY: HABITAT LOSS, POACHING OF WILDLIFE, MAN-WILDLIFE CONFLICTS 91 4.8 ENDANGERED AND ENDEMIC SPECIES OF INDIA 94 4.8.1 Common Plant species 94 4.8.2 Common Animal species 99 4.9 CONSERVATION OF BIODIVERSITY… of wilderness remaining in the future.
