Macnae (1968) proposed the term `Mangal` to denote this mangrove ecosystem. Mangroves are specialized ecosystems developed along estuarine sea coasts and river mouths in the tropical and subtropical regions of the world, mainly in the intertidal zone. Hence, the ecosystem and its biological components are under the influence of both marine and freshwater conditions. These plants are specialized to tolerate high salinity, tidal extremes, high fluctuations in wind, temperature and muddy anaerobic soil. No other groups of terrestrial plants survive well under such conditions. A muddy substratum of varying depth and consistency is necessary for their growth. The plants have special adaptations such as stilt roots, viviparous germination, salt-excreting leaves, breathing roots, and knee roots by which these plants survive in water-logged, anaerobic saline soils of coastal environments. Mangroves comprise salt tolerant plant species that occur along inter-tidal zones of rivers and seas in the form of narrow strips or as extensive patches in estuarine habitats and river deltas of tropical and sub-tropical regions. ····· 1036119817

Advancement in technology and increase in human population have resulted in increased pressure on tropical rain forests hence posing a threat on the slow regenerating forests. Kakamega is one of the tropical rain forests faced with high rate of depletion from increasing human population and logging for raw materials. Success in forest regeneration is determined by successive completion of several events in the life circle of trees such as seed production, dispersal to safe sites, germination, seedling emergency establishment and onward growth. This study was carried out to ascertain the factors impinging on regeneration in Kakamega forest. The study was done in six different vegetation types identified as primary forest,plantation, shrubland,secondary grassland, natural glade and burnt glade.Information on forest regeneration is vital for the undertaking of forest restoration work in degraded areas of a forest. ····· 1036119630

These stands also play an important role in the nutrient budget of the Mediterranean coastal waters and lakes. Phragmites australis is the major component of reed stands covering approx. 8200 ha along the shores of Lake Burullus, a Ramsar site in Egypt. Stand structure and biomass production of this plant were analyzed along the north-south and east-west gradients at monthly intervals over a period of one year (February 2003 - January 2004). For this purpose, young and old stands were selected at eight different locations in the lake. Further, some water and sediment characteristics were measured monthly at the same locations. A published temperate zone reed model (FEMME)was applied to assess the growth and cycling of carbon and nutrients among the various organs of P. australis in this sub-tropical lake. The aim was to quantify morphometric and biomass variability among reed beds along a fertility and salinity gradient in Lake Burullus. ····· 1036119596

I want you to appreciate the fact that it was wrong for the government of the day to have failed to protect, sustain and conserve the major Mau water tower in this country.The text reveals how the government and its citizens were involved in its mismanagement,degradation, and decimation because of greed and impunity. Regimes that ruled this country in the past are to blame for the massive destruction of the Mau Forest Complex by failing to put in place proper laws and regulations to protect, sustain and conserve the water tower. The citizens were not sensitized of the fundamental importance of these ecological unit. Future governments must learn a hard lesson from the mistakes of the past, and become focused and committed to matters that concern conservation of a such resource for the future generations. Everybody must become responsible, transparent and accountable not to be involved in the destruction of prime water towers.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Insects are considered to be responsible for 80-85% of all pollination, with honeybees being well known for their pollination services for many crops. The effect of managed honeybee pollination on sunflower seed yield and quality was investigated. This was done through pollinator exclusion and pollinator surveys on sunflower field plots located at different distances from managed honeybee colonies. Observations on the foraging behavior and activity of honeybees throughout the day were also made. Insect pollination improved the mass of 100 seeds (by 38%), germination percentage (by 38%) and oil content (by 36%). Moreover, visitation frequency, seed yield and quality were negatively correlated with distance to the honeybee hives. Honeybee foraging activity varied throughout the day, the highest activity being from 9h00 until 16h00, and activity was correlated with temperature. The results of this study suggest that the use of managed honeybees in sunflower crop production can effectively increase the seed quality and quantity, but additional management measures should be considered to improve production in large monocropping farms that are currently isolated from pollinator sources. ····· 1036119281

Because of the increasing water development interventions in Bangladesh, brackish water ecosystems have become a great concern at the present time. Being located in the south-eastern coastal area of Bangladesh, the Bakkhali River faces such type of threat. Due to the rubber dam construction across the river, the brackish water zone has been cut-off by establishing a distinct fresh and saline water zone affecting livelihoods of the brackish water dependent groups. The study reveals low availability of the indicator species in the zone. Finally, the study also argues that the impact on indicator species is due not only to the rubber dam construction across the river but also increased fisher folks and indiscriminate fishing practice considerably. ····· 1036119219

Facing a range of development challenges with limited resources, one of the greatest challenge in Kenya is sustaining economic development with biodiversity conservation. Covering three categories of protected areas under different governance types and management objectives (government, community and private), the research examined the general issues of how local communities in Kenya have embraced different biodiversity conservation strategies and whether support for a particular conservation strategy is primarily a function of their experiences with biodiversity decline or their relationship with the conservation authorities. The findings suggest that local people appreciate the role of protected areas in conserving biodiversity and its values, but with some resentment towards some management activities of the protected area regulators. Negative attitudes were attributed to perceived problems of living next to the protected areas while support for the management activities was associated with perceived benefits to the local people. ····· 1036118855

However, in the last decades, they have been subjected to an increasing human pressure related with recreational activities, unbridled urbanization of coastal areas and tourism, which led to an environmental quality decline of these fragile ecosystems. Often dominated by Crustaceans, the macrofauna of exposed sandy beaches occupies a key-position in the food chains and plays an important ecological role in sandy shore function. Studying abundant species at the population level might be an adequate approach to the ecosystem when the aim is to assess the potential impact of induced environmental changes. The main goals of this study are: (i) to investigate the existence of macrofaunal key species on exposed sandy beaches (ii) to study their bio-ecology and (iii) to evaluate the possibility of this bio-ecological knowledge presenting a role in global changes assessment. To accomplish this evaluation on a much wider and comprehensive scale, comparative bio-ecological studies between Atlantic and Mediterranean populations from Europe and North Africa are performed. ····· 1036118697
