Influence of Land Cover Changes and Climatic Variability on Discharge Regime of Njoro River Catchment in Kenya

Kennedy Kitonga Mwetu
This study analyzed influence of land cover changes and climatic variability from 1973 to 2000 on discharge regime of Njoro River Catchment in Kenya. Analysis focused on hydro-meteorological data of 1977-1984 (Period I) and 1992-2000 (Period II), which are the periods found with available data and Landsat imageries for the same periods. Results show a downward trend of annual discharge that corresponded to increased deforestation.

Are the Alien Species of Melastomataceae and Bombacoideae a Potential Risk for Brazilian Cerrado?

Clesnan Mendes-Rodrigues, Paulo Eugênio Oliveira, Rafaela Cabral Marinho, Rosana Romero, Marli A. Ranal
The cultivation of species in urban areas for landscaping or consumption has increased in cities surrounded by Cerrado, putting in risk the local flora. Thus, the objective of this paper was to describe seed germination and seedling emergence of five urban cultivated species of Melastomataceae and Bombacoideae and compare them with Cerrado native species to evaluate if they offer any risk to local vegetation. The seeds were collec

The Potential Productivity of Light-Chestnut Soils of the North-Western Precaspian Region in Connection with the Dynamics of Environmental Factors

Gasan Gasanov, Tatiana Asvarova, Kamil Hajiyev, Rashid Bashirov, Aishat Abdulayeva, Zaira Akhmedova, Shamil Salikhov, Nurjagan Ramazanova, Viktoria Semenova, Radjab Usmanov, Aytemir Aytemirov, Nurulislam Magomedov, Magomed Musaev
The data on receipt of photo synthetically active radiation (FAR) on the soil surface and the coefficient of its use over the years and periods of the year de-pending on the hydrothermal conditions and dynamics of harmful salts in the soil are given. The items of the changes in the species composition of phytoce-noses depending on the environmental factors are considered.

Case Study of Baiyun and Caohai Lakes Implies How to Implement Wetland Restoration/Creation

Lin Xiao, Qun Zhang, Guifeng Wei, Sixi Zhu, Fanyang Yu, Boping Han
This work discusses how to implement wetland restoration/creation from the viewpoint that wetland aquatic plants are divided into four life forms: emergent, submergent, floating and floating leaf plants. Caohai Lake and Baiyun Lake were selected to discuss the difference of the species richness changes during the creation/restoration process. Baiyun Lake and eight surrounding wetlands have been selected to discuss how the species

Microbial Inoculants Development for Bioremediation of Gasoline and Diesel Contaminated Soil

Aline Jaime Leal, Edmo Montes Rodrigues, Rita de Cássia Rocha Fernandes, Arnaldo Chaer Borges, Aline Daniela Lopes Júlio, Fernanda de Souza Freitas, Marcos Rogério Tótola
In this study, we describe the development of microbial inoculants for the bioremediation of hydrocarbon-contaminated soils through the enrichment of hydrocarbonoclastic populations in municipal solid waste compost (MSWC). Respirometric analyses were performed along with quantification of total heterotrophic bacteria and ester-linked fatty acid methyl ester (EL-FAME) profiling of the microbial communities o

Detection of Horizontal Transfer of Housekeeping and Hydrocarbons Catabolism Genes in Bacterial Genus with Potential to Application in Bioremediation Process

Edmo Montes Rodrigues, Fernanda de Souza Freitas, Tatiane de Paula Siqueira
In silico analysis can be useful to infer about the horizontal gene transfer (HGT) as well as to deduce about the evolutionary relations of catabolic genes. In this study, we performed the analysis of two housekeeping genes (fabD and rpoD) and two catabolic gene

Sargassum, Gracilaria and Ulva Exhibit Positive Antimicrobial Activity against Human Pathogens

Amrit Kumar Mishra
Bacterial resistance to pharmaceutical drugs is on rise, which emphasizes the need for screening of new drugs from natural resources. Seaweeds from the marine ecosystem are important source of bioactive compounds making them one of the major subjects for screening of various pharmaceutical drugs. So here, we assessed the bacterial growth inhibitory functions of four seaweeds Sargassum wightii

Assessing the Socioecological Perspectives of Eucalyptus Cultivation and Plantation Expansion in Laos

Xayphanya Chanthalath, Liu Yong, Mukete Beckline, Southdavone Inthilath
In Laos, the cultivation of fast growing trees as eucalypts has been promoted due to a rapid decline in natural forest cover. However, this expansion of fast growing trees might not end in a win-win situation for both humans and the environment. This paper examines the social and ecological potentials of Eucalyptus (Eucalyptus

Effect of Soil Physico-Chemical Properties and Plant Species on Bacterial Diversity in Semi-Arid Parts in Central Sudan. Part III: AL-Gaeli Region, Khartoun North

Hatil Hashim EL-Kamali, Hayat Ibrahim Hassan, Mustafa Siddig Mohamed EL-Kheir
Bacterial diversity and total viable counts of bacteria of the different soil samples from three different localities in AL-Gaeli region, Khartoum North: Kunger, Gary and WadiAb-Gadad sub-regions were carried out. Soil physical and chemical characteristics (pH, EC, SP, soluble cations: Na, K, Ca, Mg and anion P, organic carbon, total nitrogen and soil texture) in each studied sub-regions were measured. Qualitative analysis of micr
