Abstract:

Today more than 200 million people are suffering from malnutrition in Africa, a major contributing factor to this is that Africa is the continent, by a large margin, that gets least yield per cultivated hectare. The relatively poor yield is not because Africa has no cultivable land but because of the prevailing agricultural practices. Orongo is a village in western Kenya, where large parts of agriculture are threatened by severe soil erosion problems and two-thirds of the inhabitants are totally dependent on agriculture for food and economic security. Today's agricultural practices have proved

Abstract:

<p> Northwestern Indiana has land surfaces and soils that are around 15,000 years old, resulting from sediments deposited from the Wisconsinan Glaciation during the late Pleistocene period. These geologically young soils exhibit depletion of base cations and low pH's (near 4.0) which are chemically similar to much older and more intensely weathered soils. We hypothesize that FeS2 (iron pyrite) within the shale fragments of the glacial deposits was oxidized upon exposure of oxygen near the earth's surface and resulted in naturally occurring acid sulfate weathering. To test our hypothesis, we is

Abstract:

The mining of bituminous sandstone rock for the purpose of extracting bitumen has created a need for reclamation. One such mine is located in northern Logan County. Their mining operation involves removing large sections of sandstone, which is impregnated with bitumen, and crushing it to sand-sized material. The sand-sized material is then mixed with organic solvents which extract the bitumen. Once separated, the bitumen is stored for future refinement and the spent sand is stockpiled for later disposal. The spent sands or waste material are referred to as tar sand tailings. These tailings hav

Abstract:

Quaking aspen (Populus tremuloides) clones within close proximity to one another can exhibit drastically different levels of browsing by ungulates. The objectives of this study were to (1) determine interclonal differences in plant chemistry between adjacent clones exhibiting different degrees of herbivory which may influence the browsing behavior and patterns of ungulates, and (2) determine if correlation exists in the levels of salicortin and tremulacin between current year's suckers and current year's growth on older trees. This second objective was meant to indicate a protocol for land man

Full text

Abstract:

In the past decade the wetlands of the Swan Coastal Plain (SCP) region of Western Australia have been subject to increasing fire frequency and intensity. Whilst wetland sediment fires (also known as peat fires) on the SCP are not new phenomena, the increased frequency, duration and extent of combustion have been concomitant with an increase in urbanisation and reduction in average annual rainfall for the region. This has led to a decrease in ground- and surface-water levels which, in turn, has increased the susceptibility of the wetland sediments to ignition and combustion events. Increased we

Abstract:

Sinkhole flooding on the urban karst area of Bowling Green, Kentucky, was studied by investigating past flood events in the South Sunrise/Media Drive Sinkhole. The actual flood levels of four floods were compared to levels calculated by an empirical runoff determination method. Outflow capacity tests and dye tracing revealed the nature of drainage within the karst depression. The Soil Conservation Service runoff determination method and the three-hour maximum rainfall event were used to estimate the level of flooding. Three of the four flood events studied provided deviations between the actu

Abstract:

The purpose of this research is to identify factors that contribute to wood fuel consumption as a space heating source and estimate a county-wide proportion for wood fuel consuming households. In addition, environmental problems associated with deforestation such as erosion and loss of wildlife habitat are delineated; moreover, air pollution resulting from wood fuel emissions are discussed. An exhaustive literature review provided the basis for the study. Data on Warren County wood fuel consumption patterns were derived from a mail survey. Proportion estimates were tested by using a classical

As a part of the department functioning, a description of its main research tasks and publications, which had played an essential part while formulating theory and methodology of urban planning after the 2nd World War in Czechoslovakia, are introduced. Special attention is paid to tasks and publications whose authors and research workers applied interdisciplinary a

Abstract:

Determining how biodiversity is produced and maintained remains one of the fundamental questions in ecology. The phenomenon of diversification, which occurs via the interplay of speciation and extinction, holds the key to understanding this question. Diversification is crucial to understanding how biodiversity is distributed over and varies across spatial and temporal scales. By and large, studies of diversification are biased towards the Neotropics and temperate regions, with very few studies in the tropics of Asia. This study makes an effort to address this gap by examining the process

Abstract:

I used a finer scale data of 156 published plots across the entire latitudinal range of WG, covering most of the protected forests. The pruned phylogeny for this study consisted of 367 species, of which ~ 50% are taxa endemic to WG. I first tested the southern refuge hypothesis by analysing the PE of all 367 species. my results show that plots significant for PE were more in the southern latitudes, indicating the presence of range restricted clades predominantly in the southern WG. I then partitioned the data to explore the contribution of endemics and non-endemics to the overall PE patt

Abstract:

The Western Ghats (WG) orography that runs along the western coast of peninsular India, is a long and narrow mountain chain with an average height of about 1200 meters. The orientation of this orography is approximately perpendicular to the mean low–level winds over the eastern Arabian Sea during boreal summer season (June–September; JJAS). In JJAS, while western sides of this orography receive high intensity of precipitation, a region to the lee side of the mountain, termed as the Bay of Bengal Cold Pool (BoB–CP), receive very less precipitation.

Abstract:

The Indian subcontinent is a considered a mega biodiverse region with representative regions belonging to three of the 35 global biodiversity hotspots, including the Western Ghats in Peninsular India and the Eastern Himalaya. These areas are threatened with biodiversity decline due to habitat loss and other factors such as climate change. Many species and populations may be extirpated even before they have been discovered, as these areas have not been adequately surveyed, especially for lower vertebrates and invertebrates. The region has over 300 species of snakes, but they are poorly st

Abstract:

Human activities that involve interactions amongst three players i.e. nature, humans and technology, continue to impact negatively on the Earth's biosphere. The impact is tremendous: consumption of resources at an unsustainable level leading to rapid loss of natural resources and biodiversity. The plea to reverse this negative trend is as valid now as it were many years ago. While some progress has been made to develop strategies to wisely manage and protect the Earth's resources, the state of the environment is still fragile. Strategies are far from satisfactory: hence the grounds for a

Abstract:

In comparison with North America, there is a poor level of taxonomic diversity in the Australian freshwater mussel fauna. Seventeen endemic hyriid species have been recorded in this country, while over 30 species have been recorded from one reach of a US river. While there have been no extinctions recorded among Australian mussel species, there are several species under threat, and mussel populations in many river systems are in serious decline. One of these catchments, the Hawkesbury-Nepean River, is considered to be among the most highly impacted of the eastern coastal rivers. Mussel populat
