Assessing the impact of anthropogenic activities on forest ecosystems dynamics is valuable in managing and maintaining the long-term productivity of forests and ensuring forest ecosystem sustainability and ecological balance. In view of this, the objective of this study was to evaluate the induced effects of anthropogenic activities on the forest˗savanna zones in Northern Ghana. The study assessed the impacts on the...

Intolerable sulfide emission was spotted at several areas in tidal flats of the Ariake Sea, Japan. Sulfide is naturally produced in tidal flats and rapidly oxidized by sulfur-oxidizing bacteria (SOB). This makes them important players in controlling released sulfide by sulfate-reducing bacteria. A part of SOB can grow heterotrophically and we isolated them from a conserved muddy tidal flat in the Midorikawa Estuary,... Read more.

Since its 2009 detection in Virginia hibernacula, the fungal pathogen Pseudogymnoascus destructans causing White-nose Syndrome (WNS) has had a marked impact on cave bats locally. From 2008-2013, we documented numeric and physiologic changes in cave bats through fall swarm (FS), early hibernation (EH), and late hibernation (LH) capture and banding surveys at 18 hibernacula in western Virginia. We coupled active surveys... Read more.

Wetlands support livelihoods of communities living around them as in the Nyando Papyrus Wetland in Kenya. The Nyando Papyrus Wetlands provide multiple resources hence there are multiple uses and users who often overlap spatially and seasonally causing conflicts. More claims are being exerted on these wetland resources from different sides and institutional levels with different actors. The actors involved refer to... Read more.

Historically speaking, ‘ecology’ today is an interdisciplinary as well as complex science. Modern ecology characterises more facts than possibly known. Any ecologist is today a specialist, with favourite and specialised questions. And hence, there are different sub-disciplines in ecology with its own set of concept(s) and all try to unify looking only at ‘ecology’. Moreover, it is now an... Read more.

The present study was an attempt to assess and evaluate the distribution, diversity and occurrence of spider community in Gulmarg Wildlife Sanctuary. India has 59 of the 110 spider families and at least, 1442 formally described species of the 39,000 known worldwide. Documenting spider assemblages assumes greater importance in the context of current rate of loss and degradation of forests which is known to have... Read more.

Rwampara hills located in South Western Uganda have long been subjected to intensive degradation due to increased human activities. The hills have been left bare as a result of vegetation clearing for agricultural land, charcoal burning and grazing. In 1998, the National Environmental Management Authority (NEMA) attempted to restore the degraded hilly areas with the aim of establishing the restoration potential. With... Read more.

The problem of environmental pollution is not simple and easy to ignore because it affects the survival and normal functioning of an ecosystem by changing the overall healthy interaction between its components and after once it occurs, will be difficult to control. Fortunately, in the town of Debre Berhan (Tebasie), it is a common phenomenon due to the discharge of untreated liquid and solid wastes from industrial and... Read more.

Major challenges to the landscape level conservation intervention are to monitor and evaluate the conservation impacts in an accurate and cost-effective manner. Threat reduction assessment (TRA) has been proposed as a method to measure conservation success and as a proxy measurement of conservation impacts and monitoring threats. We conducted TRAs to evaluate the effectiveness of Nepal’s Terai Arc Landscape (TAL)... Read more.

In general, this study was to encourage students to pursue, environmental science, biology and tourism programmes at tertiary level by embarking on educational tour with tertiary students to the study area, while at the same time, the paper performs its functions such as finding out how residents were empowered in funding, capacity building and conflict resolution skills in tourism development. Specifically, the study... Read more.

Human activities have modified the environment over the years. Urbanization, agriculture lumbering, mining and other land uses have substantially altered the Earth’s surface. Land use and the resultant change in land cover have significant effects on ecological, environmental and hydrologic systems and processes. An understanding of past and present land-cover change, together with an analysis of potential future... Read more.

The present work was carried out in the in river Jhelum of Kashmir Himalaya to assess the density and diversity of fungal flora, to isolate and identify the fungi from the water along with some physical parameters like pH and temperature which was carried out between June-November, 2011 at four sites differing from each other markedly in terms of biotic and abiotic factors. During the study, a variety of fungal strains... Read more.

Forests can capture and retain enormous amount of carbon over long period of time. Their role in carbon emission balance is also well documented. However, especially in developing country, wide spread deforestation and forest degradation is continuing unknowingly and deliberately. This study was conducted to estimate carbon stock in dry Afromontane forest type of Danaba community forest (CF) of Oromia Regional State of... Read more.

An ecological study on population structure of rodents was conducted in Alage, Southern Ethiopia. Sherman live traps were used to capture rodents in four habitats and trapping sessions. A total of 684 rodents that represented 11 species were captured. Regarding population size and density, Mastomys natalensis was the dominant species followed by Arvicanthis dembeensis while the least was observed in Graphiurus murinus... Read more.

A six months investigation on the environmental impact of fish cage culture on surface water and sediment of the Lagos lagoon were studied monthly from February 2011 to July 2011. Samples were collected from three stations, 1 (upstream of cage culture site), 2 (cage culture site) and 3 (downstream of cage culture site) between 07:00 and 11:00 h. During this period, the surface water ranged between 23.34 ± 3.39... Read more.

Repeated observations of forest development using permanent plots can map pathways and rates of primary succession at the individual plant, the plot and the community level. This study re-measures the trees in 34 100 m2 plots that were first sampled in 1987 to document recent and to predict continued forest development for a mixed-conifer forest established on a volcanic mudflow formed at a 2000-m elevation in Lassen...

In the developing countries in general, industrial effluents are discharged into the rainwater evacuation channels, on the street, or in nature, without treatment, causing immense environmental damages. This work aimed to propose, at a pilot scale, a test treatment, based on a Pistia stratiotes L., 1753 pond system, to purify wastewater from the Cotton Development Company of Cameroon (CDCC) oil mill, in Maroua...

The composition and diversity of planktonic algae in a sluggish tidal freshwater/brackish mangrove dominated creek (Ipa Itako) part of the Lagos lagoon was investigated for twelve months (February 2010 - January 2011). The surface water pH varied between 6.5 (December 2010) and 8.6 (August 2010) indicating a slightly acidic to alkaline nature of the creek. The salinity was higher during the dry months (November- April)... Read more.

Africa’s attractiveness to potential biofuel investors is based on the assumption that there is plenty of unused land available for investment in different countries of the continent. However, their postulations are not based on any concrete studies on land available at country, regional or local level. This study investigates land availability for potential biofuel investment at the local level, using Rufiji... Read more.
