A study of the Grasses of South-East Rajasthan,India

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Grasses belong to family Poaceae and have over 10,000 members all being fundamentally different from other plants.Restoration of plant communities,maintenance of biodiversity,landscaping,erosion control are some of the ecological uses of grasses.The use of large number of plant species by the tribals to meet their daily requirements is largely due to the prevalence of diversity of vegetation in South East Rajasthan.The South-Eastern rajasthan boasts a maximum number of grass species.Due to recurrent droughts and overgrazing several persistent grass species are dwindling and many of them are on the verge of extinction.Due to lack of awareness and research on this important group of plants,people of this region are unkbown of this wealth of heritage.In the present study therefore an attempt has been made to bring out an updated account of the grasses of South East Rajasthan and efforts are made to explore their maximum utility. ····· 10361114024

Shorttitle The Asiatic one-horned Rhinoceros/ Greater Indian One-horned Rhinoceros (Rhinoceros unicornis) is endangered species of Indian mega fauna.Once Indian One-horned rhinoceros (Rhinoceros unicornis) roamed over the Indus, Gangetic to Brahamputra flood plains of the Indian sub- continent.At present the Great Indian One Horned Rhinoceros has total population of about 2800 animals in India and Nepal. In India, currently its population is restricted to four natural populations in Assam viz Kaziranga, Manas, Orang (Rajiv Gandhi WLS) and Pobitora, two natural populations in West Bengal viz Jaldapara and Gorumara and one re- introduced population in Dudhwa NP and one migratory population in Katerniaghat UP.In Nepal,the three rhino populations are in Royal Chitwan NP, Royal Bardia N.P and Sulkhlaphanta WLS. The Rhino of Royal Chitwan N.P. is a natural population while Royal Bardia NP and Sukhlaphanta WLS have the re- introduced population. The Kaziranga National Park in Assam (India) has the highest population of Rhino (2084) and Pobitora WLS (84 rhinos in 16 sq km area) followed by Royal Chitwan N.P. in Nepal (408 rhinos) in 2010. ····· 10361114020

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
In Namibia, most studies favors most valuable commercial fish species. This has resulted in a poor understanding of less valuable fish species and could lead to their eventual depletion. Thus, this book disregard the commercial status of fish species composition to provide a better understanding of overall diversity taking into consideration the influence of environmental variability. The analysis has highlighted fascinating biodiversity trends in marine environment, and this should be highly useful to fishery managers and conservation scientists for better management of fisheries resources, or anyone else in fishery fields. ····· 10361114007

Twenty five years of Rhino Reintroduction Programme

Rhino Reintroduction Programme in Dudhwa National Park /Tiger Reserve, in 2010, is going to celebrate its 25 years of successful reintroduction in the field of wildlife conservation and management. For the first time in India reintroduction of rhinos from Pabitora Wildlife Sanctuary, Assam and Chitwan National Park, Nepal, rhinos reintroduced into former range of its distribution in Dudhwa NP took place in two phases in 1984 and 1985.Of the total of nine rhinos translocate to Dudhwa Tiger Reserve seven survived in excellent health and these consisted of the young female and both the males of 1984 translocation from Assam, and all four young females of the 1985 from Nepal. Thus, these seven rhinos constituted the seed population of rhinos at Dudhwa National Park. In 1988, one adult male from Assam died after fought with another dominant male. Again in 1991, a female, from Nepal died due internal infection and abortion. She also lost her male calf in 1993 killed by the dominating male. The present rhino population of total 30 rhino comprise of 25 calves of different age and 5 rhinos of founder population (2010). ····· 10361114005

ENHANCED DEGRADATION OF POLYCHLORINATED BIPHENYLS

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
There is a worldwide initiative to remove polychlorinated biphenyls (PCBs) from the environment because of their potential hazard. Animal experiments have shown they can produce liver damage, developmental defects and even cancer. Thirty per cent of the 310,000 tons of PCBs that have been produced globally are now considered as persistent toxicants in the environment. To date, only 4% have been successfully treated. Although a number of technologies are in existence for the treatment of persistent organic pollutants (POPs), they do have several drawbacks including the production of toxic volatiles in incinerators and high cost associated with these procedures. On the other hand, successful bioremediation is relatively inexpensive, as shown for polyaromatic hydrocarbons (PAH) degradation, with the added advantages of being able to be carried out in situ. In this study, preliminary experiments demonstrated that certain surfactants enhance PCB degradation in aqueous solution in the presence of enzymes, in a concentration-dependent manner. These surfactants have not been previously reported as enhancers in PCB degradation. ····· 10361113698

Maintaining tree species diversity in community forests is important for ecological and economic benefits. This study explored the status of tree species richness, population distribution and number of desired tree species in mid-hills of Nepal. It has evaluated different forest management systems- community forests, National Park and government managed forests. Group discussions with community forest user group members, key informant surveys were done to obtain information regarding existing forestry practices, preferences and goal of forestry activities. The results showed that the total species richness was highest in some community forests as similar to the National Park where communities have multiple species preferences. However, it was lower in other community forests, and lowest in the government managed forest where high pressure on the specific species. Communities are maintaining all types of tree species but more preferred/useful one in many cases. Community forestry can contribute to maintain the tree species diversity but need to run extension programmes about forest management and tree species diversity and also link it to the income options. ····· 10361113563

Basic Aspects of Walnut Allelopathy

····· lezzter Preis 61.20€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Allelopathy is one of the oldest examples of environmental interactions between higher plants and other living organisms. Biologists, chemists, microbiologists, ecologists, molecular genetists and other scientists work together in this scientific discipline. Assessment of the allelopathic effects is complicated as it depends on the donor and acceptor organisms, and involves not only the toxicity of individual allelochemicals, but also their interactive effects, including antagonistic and synergistic effects. The present European Union environmental policy requests to apply procedures and practices that minimize the toxic environmental effects of the allelochemicals. The present book provides a concise introduction to the walnut allelopathy in the field and laboratory allelopathic tests and molecular background of this phenomenon. Short characteristics of Juglandaceae, and effect of walnut and juglone on other organisms including human are included too. Students and researchers new to the subject may find this text an invaluable guide. ····· 10361113414

Range Productivity and Plant Preference

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
The full potential of the interaction between plant and animal systems is generally not well known and is seldom reached with presently used management skills, especially under common open grazing systems. The range management practices adopted are more plant oriented and most of the interventions may not consider animal type or feeding behavior. This situation may lead to shortcomings in range management process as related to decision making concerning interventions and grazing management planning. This book is addressing means of better understanding of feeding behavior towards development of management strategies that aim to maximizing the use of the existing ecosystem and at the same time increasing animal production. Parameters investigated included distance walked by sheep and goats in open grazing system and at different plant growth stages, across open and protected range areas, in addition to response of animals in terms of metabolizable energy intake and its relation to maintenance and energy required for walking. Variations in plant selection as indicated by use of different animals were also investigated in the context of plant types and plant growth characteristics. ····· 10361113399

The Ganges River is the most important source for water resources for both Bangladesh & India, and resulting in many conflicts arising between these two countries. Farakka Barrage is a low height dam, constructed mainly to divert water back into the Hoogly-Bhagirathi channel. The first water sharing agreement regarding Farakka was signed between India & Bangladesh, on 5/11/1977, for the duration of 5 years. After 14 years, an agreement between Bangladesh & India on Sharing the Ganges water `Ganges Water Sharing Treaty` signed on 12 December 1996. Water is a source of conflict, mistrusts, and disputes between the three riparian states of Ganges basin Indian diversions of Ganges water through Farakka barrage, is a long-term source of tremendous political tensions, mistrust and non- cooperation between India and Bangladesh. Flooding in monsoon and reduction of flow on dry season causes tremendous socio-economic & environmental loss for Bangladesh like agriculture, fishery, navigation, industry & vegetation. It has severely affected the downstream river regime of the Ganges- Padma in Bangladesh. ····· 10361113308

The present study compared Sand Forest bird assemblages found in a communal land area with that of the Tembe Elephant Park, and determined the habitat preference and status of selected herbivore species within the Tembe Elephant Park in KwaZulu-Natal, South Africa. The main purpose of the study was to compare Sand Forest bird assemblages found in the Tshanini Community Conservation Area, which is characterised by low levels of human utilisation, with that of the Tembe Elephant Park, which is characterised by wildlife utilisation. This approach was used to determine the biological importance of this communal land area in contributing towards the conservation of the rare Sand Forest habitat. The second purpose of the study was to identify possible competition between selected herbivore species within the Tembe Elephant Park and/or a decrease in numbers of rare species. It is important to protect a viable portion of the preferred habitat of every target species within a reserve, and to keep competition with rare species to a minimum for the long-term survival of the regional biodiversity. ····· 10361113269

In coastal area interactions among air, water and soil take place. The nature of water and amplitude of the tidal regimes resulted in the poor understanding.The present study focused on a segment of the coastal zone of Bangladesh. Soils collected from the three islands were found to be rather similar as regard to chemical properties, although some variables differed significantly among the islands. No general pattern of significant variation was found location wise. Element concentrations of leaves of Sonneratia apetala showed significant variations among the islands. In most cases, location 2 of the river Buragauranga had higher values of the variables. Among the phytoplankton genera, 8 belong to class Bacillaiophyceae. Dominant phytoplankton was Trachelomonas sp. and was found in all three locations. Phytoplankton diversity was high in location 2. Principal component analysis (PCA) showed that Trachelomonas sp. has negative significant correlation with principal component one but have positive relation with Coscinodiscus sp. This book will help in understanding the coastal zone as holistic approaches have been taken and help in conservation and management of coastal resources. ····· 10361113210

SEDIMENT, NATURAL FOOD AND WATER QUALITY IN TIGER SHRIMP POND

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Sediment, natural food & water condition in shrimp ponds have been investigated in Malaysia. Cation exchange capacity varies with soil texture while soil organic matter varies with pond age. The dynamics of macro & microelements in pond & sediment waters were not distinct in old & new ponds, but were influenced by accumulation process of living organisms, water exchange & precipitation of ions. Gastropod was the dominant macrobenthos followed by harpacticoid copepod as meiobenthos. About 30% of zooplankton decreased within one month after the release of post larvae into the ponds which revealed the significance of natural foods in culture ponds in reducing the production cost & increasing pond yield. Stomach content analysis showed that the higher content of natural food items was found in the stomach of shrimps from old ponds. The population of fungi in shrimp pond soil was mostly of Aspergillus & Penicillium which were similar to the terrestrial soil fungi. The results showed that many activities i.e., feeding, stocking density, weather condition, accumulation of organic matters & pond age governed the quality of pond water, shrimp growth, production & pond ecosystem. ····· 10361113162

Champion Block is one of the important plantation blocks of Forest Research Institute in which Chir pine forests was established. Phyto-diversity study was carried out in this Block. The specific strands within the Block were sampled with the help of quadrates of suitable size viz.10m x 10m for trees, 5m x 5m shrubs for and 1m x 1m for herbs. The data regarding no. of species, diameter of trees, collar diameter of shrubs, height of the trees and shrubs were obtained. The data so obtained was analyzed for frequency, species richness, dominance, species density and IVI. It was concluded from the study that if Chir pine forest is protected, the diversity of plants can be enhanced. The unprotected/open Chir pine forests mostly has grass covers and needles of pines on its floor, much of the regenerated species in these unprotected forests are damaged due to intense biotic pressure and frequent forest fires in the western Himalayan region. It is cleared from this study that protected Champion block of pine area have more diversity of plants and regeneration of species than the unprotected pine forest area of Himalayan region. ····· 10361113036

Optimal practices in the afforestation of cutaway peatlands

Peat extraction occurs right across northern Europe and North America. Afforestation has been considered one of the most feasible after-use alternatives for the degraded habitats that are cutaway peatlands`. In Ireland, research was initiated to generate optimal practices that represent the most appropriate methods (species, seedling characteristics and management operations) for the successful afforestation of industrial cutaway peatlands and the creation of new sustainable forests, compatible with environmental imperatives. This research established that with good planning and the application of site- specific establishment procedures, satisfactory results could be obtained, using intensive site evaluation procedures. While Norway spruce may be the most suitable commercial forest species, a range of other conifer and broadleaved species can be established successfully. The variation in site conditions encountered in any given site means that, not one, but several species might flourish within a given area, thus enhancing the sustainability of these new forests. This research should help students, researchers as well as foresters and land managers. ····· 10361113027

It is paramount that the richest diversity of freshwater fish species on the earth is protected not only for its intrinsic value but also for its far-reaching extrinsic value to humans and entire ecosystems. This study therefore focuses on the effects of naturally occurring phenomena, such as drought, and anoxic events, on the icthyofauna of five ox-bow lakes at one Amazonian area of the Yavarí River, Perú. The data have been used to assess the effectiveness and reliability of fishing methods and to monitor changes in diversity, abundance and richness across the three years of 2005, 2006 and 2007 in line with normal, drought and anoxic events respectively.This study concludes that fish in Amazonian lakes are well evolved and adapted to cope with naturally occurring fluctuations in water levels and specifically with droughts during the dry season. From this study, it also becomes apparent that local and trans-boundary monitoring, management and regulatory schemes are needed. ····· 10361113023

Bottom soil plays an important role in determining the productivity of fish ponds by providing sustenance to fish food organisms and, thereby, the growth of fishes. The behaviour and response of different nutrient inputs, used for improving the productivity of such culture system, are also influenced largely by the nature and properties of the pond soils. The book provides some basic information about the methods of assessing and also maintaining threshold levels of different plant nutrients in fish ponds through soil system based approach for increasing their productivity. ····· 10361113017

Aspects of the phytoplankton ecology in Lake Chivero, Harare, Zimbabwe

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Lake Chivero was built in 1952 to supply drinking water to the city of Harare and became eutrophic due to discharges of sewage effluent. Algal blooms have become a major problem whilst cases of gastroenteritis and liver cancer have increased dramatically over the last decades. To evaluate the potential health threat, the phytoplankton community in the reservoir was investigated. Inorganic nutrient (2.4-3.0 mg P l-1 and 1.4-3.2 mg N l -1) and conductivity (1433-368 mS cm-1) as well as phytoplankton biomass concentrations (0.8-7.6 mgl-1) were very high. Primary production had increased significantly since 1979, suggesting that the eutrophication problem has increased. Microcystis dominated the phytoplankton community with a low biodiversity (0.92 bits ind.-1). Strains of Microcystis from the reservoir were tested for toxicity and contained high concentrations of microcystin indicating a highly serious health threat. Moreover, the same algal blooms may explain the occurrence of fish kills in the lake that was observed in 1996. A reduction of nutrient inputs in the reservoir is urgently required to prevent the occurrence of toxic algal blooms in the future. ····· 10361113014

Arten und Lebensräume der Bergbaufolgelandschaften

für 64.00€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Die Gewinnung von Braunkohle steht in der Kritik. Klimawandel und Umweltzerstörung sind die bestimmenden Schlagworte in den öffentlichen Debatten. Ein Paradebeispiel für den Raubbau an der Natur ist der Braunkohlenbergbau der DDR. Die Mangelwirtschaft der DDR verhinderte die gesetzlich vorgeschriebene Rekultivierung auf großer Fläche und förderte umweltschädliche Handlungsweisen der Betriebe. Die Sanierung der Braunkohlentagebaue ist daher eine der großen Gemeinschaftsaufgaben des Bundes und der betroffenen Länder in der Altlastensanierung. Doch bereits zu DDR-Zeiten gab es Wissenschaftler und engagierte private Naturfreunde, die erkannten, wie sich nach der Zerstörung neue Lebensräume entwickelten: Liegengelassene, nicht rekultivierte Flächen sind auch Räume spontaner Entwicklungen, Standorte mit extremen Boden-, Wasser,- und Mikroklimaeigenschaften. Sie bieten damit zahlreichen spezialisierten und gefährdeten Arten der Flora und Fauna Lebensräume. Einige wenige Kippenflächen und Halden wurden bereits damals unter Schutz gestellt. Heute sind 17 SPA-Gebiete, 28 FFH-Gebiete und 33 Naturschutzgebiete auf Flächen des Braunkohlenbergbaus in Ostdeutschland ausgewiesen. Durch die Sanierung der Braunkohlentagebaue wurden in dem vergangenen Vierteljahrhundert die meisten Umweltschäden erfolgreich und nachhaltig beseitigt. Flächen für Tourismus und wirtschaftliche Nachnutzung sind entstanden. Traktoren und Holzerntemaschinen sind in den Bergbaufolgelandschaften normale Anblicke. Doch wie steht es um die Naturschätze in den Bergbaufolgelandschaften Unter der Leitung von zwei wissenschaftlichen Institutionen und dem bundeseigenen Projektträger der Braunkohlensanierung haben insgesamt 6 Institutionen an diesem Werk mitgearbeitet. Über 100 Fachleute haben ihr Wissen, Daten und Bildmaterial zur Verfügung gestellt. Es ist ein einzigartiges Werk entstanden, das einen Einblick in die aktuelle Situation erlaubt. Für 29 Artengruppen mit vielen Hundert Arten werden die aktuelle Situation, erwartbare Trends sowie Möglichkeiten zur Stabilisierung und positiven Entwicklung detailliert beschrieben. Die Vergleiche zwischen dem Mitteldeutschen Revier, zwischen den Städten Leipzig, Halle, Gräfenhainichen und Altenburg, und dem Lausitzer Revier, um Cottbus südwärts bis in den Raum Weißwasser-Hoyerswerda-Görlitz, bringen spannende Erkenntnisse zur Verbreitung einzelner Arten und Gruppen. Die Ergebnisse zu Arten und deren Häufigkeiten sind weit über die Braunkohlefolgelandschaften von Bedeutung. Steckbriefe von 25 verschiedenen Biotop- und Vegetationstypen in den Bergbaufolgelandschaften beschreiben die Lebensräume und ihre Entwicklungstendenzen. Es werden zahlreiche Hinweise zum Schutz und der Pflege naturschutzrelevanter Biotoptypen gegeben. Dynamik und Vielfalt sind immer noch prägende Prozesse in den Bergbaufolgelandschaften. Das dem so ist, ist auch ein großer Verdienst privater und öffentlicher Naturschutzstiftungen. Deren aktive Mitarbeit an diesem Werk ermöglichte das dort vorhandene Wissen und die praktischen Erfolge in einer gemeinsamen Publikation darzustellen. Das Buch wendet sich damit an alle, die in der Rekultivierung von Bergbauflächen arbeiten, Wissenschaftler und Studierende aus den Bereichen der Biologie, Geoökologie und der Landschaftsgestaltung, an Spezialisten für die aufgeführten Artengruppen sowie an alle Naturbegeisterten. ····· 10361108235
