It is vital to manage this valuable resource not only for its intrinsic value but for its significant extrinsic value to humans and the entire Amazon ecosystem. The present study contributes new information on the biology of two common Amazonian fish species. The relationship between the weight and length of Serrasalmus rhombeus (Piranha Blanco) and Potamorhina latior (Llambina) from three oxbow lakes is examined, and how different habitat types influence fish development. Age and growth are estimated by calcified microstructure analysis. This information is vital in that it may guide future fisheries research on economically important species in the Amazon and ultimately contribute to sustainable fisheries policy and species management plans. ····· 10361135615
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The rapid trends of global climate change were noticed over the last decades. Both climate change and human intervention have implications to natural ecosystems. Lake ecosystems are highly fragile and vulnerable to such changes. This study was initiated with purpose of assessing the impact of climate change and human intervention on ecosystem services of Lake Alemaya and to study its socio-economic consequences. The result of the study showed that human intervention highly contributed for the gradual deterioration and final disappearance of the lake than micro-climatic factors. It also revealed that the final disappearance of the lake with its ecosystem services negatively affected the livelihood of the local community. This book, therefore, recommends strong policy and management system to restore Lake Alemaya with its ecosystems and protect similar lakes in Ethiopia. ····· 10361135597

The study aimed at evaluating the current status of the Traditional Arabic Palestinian Herbal Medicine (TAPHM) in the Qalqilia District, determining medicinal plants still in use, their primary health care importance at the household level, economic value, conservation status, and their healing potentials. The work also aimed at documenting and preserving the traditional knowledge associated with the use of medicinal plants before its disappearance. Information was collected from 200 people: 174 women and 26 men, using specially designed questionnaires. The participants included 3 local healers, and 197 well known informants. One hundred and sixteen medicinal plants were reported to be used as a cure for 62 ailments. The studied plants belong to 46 families and 103 genera.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Niger Delta is a region characterized with fierce violent conflict for more than a decade now.The conflict is between successive Nigerian Governments and their collaborating oil companies, and militant groups from the region. And the core issues in the conflict are the socio-economic deprivations and denial of resource control which were occasioned by corporate malfeasance and indifference of successive Nigerian Governments to the plight, demands and aspirations of the people of the region. The Nigerian Government however proposed an amnesty policy in June 2009 as a non-violent measure to address the crisis in the region. This study throws an insight on the policy and argues that the policy which aims solely on disarming and integrating the militants into the society has no feasibility of ensuring a genuine and lasting peace in the long troubled region. This is because its focus is not on the root cause of the crisis. Thus it argues that addressing the issue of human rights whose lack is the root cause of the crisis and whose provision has always been the demands and the aspirations of the people will instead engender a genuine and lasting peace in the region. ····· 10361134595

Synonyms and differentiating characteristics of the following five species are presented and pallets and shells illustrated: Bankia rochi, B. campanellata, Dicyathifer manni, Lyrodus pedicellatus and Martesia striata. These are reported for the first time from Pakistan. No relation between size of wood and number of borers was found. In most cases, wood contained individuals of one species. However, occurrence of 2 or 3 species in the same wood was not uncommon. D. manni and B. rochi are large size species which may grow over 24.0 cm in body length, whereas L. pedicellatus is a small size species. Recruitment of L. pedicellatus continued throughout the year. Although B. rochi showed year round recruitment in Sandspit, it occurred twice a year in Port Qasim area. No infestation of borers was found in Clifton mangroves. ····· 10361134541

This is a cause for concern in both protected and private lands in Namibia and elsewhere. Therefore, the objective of this study was to determine the impact of large herbivores on soils and vegetation around water points in the Waterberg Plateau Park. The results indicated lower plant densities, cover, basal areas, diversity and richness at water points (0m), than the further distances from the water. Height class and basal area class distributions generally portrayed a similar trend throughout the study area. Hierarchical Cluster Analysis classified the vegetation plots into 10 main clusters based on species presence/absence data. Detrended Correspondence Analysis indicated a complex interaction of gradients, which have influenced the patterns in species composition. Canonical Correspondence Analysis indicated that phosphorus, cation exchange capacity and clay accounted for significant variation in species composition. ····· 10361134467

Similarly soil samples were collected from each stratum and analyzed for physical and chemical properties. Soil texture, pH, Nitrogen, Phosphorus, potassium, organic matter were determined by hydrometer, pH meter, Kjeldhal, Olsens Bicarbonate, Flame Photometer and Walkey-Black Methods respectively. Local use and management practice were assessed through questionnaire survey. High density and frequency of V.jatamansi were found in strata with loamy sand soil having comparatively higher Nitrogen, Organic matter, Potassium, pH and Moisture content. It is locally used in urinary problem, headache, eye problem and cutting wound. It should be conserved and managed efficiently for medicinal and commercial purpose. ····· 10361134445
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Vegetation maps and bioclimatic zone classifications communicate the vegetation of an area and are used to explain how the environment regulates the occurrence of plants on large scales. Climatic parameters, floristic characteristics, or edaphic features have been relied upon as decisive factors for developing such schemes. It has been deduced that plants moved between corresponding bioclimatic areas should thrive in the target location, whereas plants moved from a different zone should languish. This notion is routinely applied in forestry and horticulture but actual tests of the validity of bioclimatic maps are scanty. Here the Finnish bioclimatic vegetation zone system is tested. Relying on the plant collection of the Botanic Garden of the University of Helsinki, which is situated at the northern limit of the hemiboreal zone, the relation between the plants provenance and survival was studied. The results gave support to the zone system, and especially its hierarchical zonation. The study also shows the importance of botanic gardens paying due attention to information management and curational practices for maintaining the scientific value of their collections. ····· 10361134311
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Erica arborea is the dominant tree of the uppermost forest zone of the Simen Mountains National Park, Ethiopia. Only six other woody species are found between 3.100 m and 3.600 m elevation at the investigated sites. Many E. arborea stands of the Simen Mountains are considered endangered due to insufficient regeneration attributed to changes in land use. In this study the influence of disturbances on the stand structure, species composition, density of mature tree, saplings and seedlings, as well as on the soil seed bank were examined and the causes of seedling mortality, micro site condition, seed germination requirement and survival of E. arborea were investigated at three sites. The overall vertical distribution of the seeds in the soil was similar in all stands, with the highest densities occurring in the upper five centimetres of soil and gradually decreasing densities with increasing depth. For the successful germination of E. arborea and Hypericum revolutum charred soil showed great performance, compared to other seedbed conditions (exposed mineral soil, sand, forest floor and nursery soils). Fire has a profound positive effect on Erica regeneration. ····· 10361134266· 1 · ::::: · 2 ·· 3 ·· 4 ·· 5 ·· 6 ·· 7 ·· 8 · ::::: · 30 ·
