Evolutionary history of Nile perch Lates sp. inferred from mitochondrial DNA variation analyses

Mwanja, Matthew T.; Muwanika, Vincent B.; Masembe, Charles; Nyakaana, Silvester; Waiswa Mwanja, Wilson (Zoological Studies, 2013)

Evolutionary histories of aquatic species are often characterized by distinct patterns of genetic variation, which in part reflect drainage evolution. In the present study, the consequences of paleo-environmental changes ...

Natural history of Mycoplasma genitalium Infection in a Cohort of Female Sex Workers in Kampala, Uganda

Vandepitte, Judith; Vandepitte, Judith; Weiss, Helen A.; Kyakuwa, Nassim; Nakubulwa, Susan; Muller, Etienne; Buvé, Anne; Van der Stuyft, Patrick; Hayes, Richard; Grosskurth, Heiner (Sexually transmitted diseases, 2013)

There have been few studies of the natural history of Mycoplasma genitalium in women. We investigated patterns of clearance and recurrence of untreated M. genitalium infection in a cohort of female sex workers in ...

Late holocene trends of phytoplankton productivity and anoxia as inferred from diatom and geochemical proxies in Lake Victoria, Eastern Africa

Andama, M.; Lejju, J. B.; Tolo, C. U. (Biogeosciences Discussions, 2013)

Lake Victoria ecosystem has undergone major ecological changes in the recent decades. Sedimentary diatom analysis and Fe/Mn determined by Energy Dispersive X-ray Fluorescence (EDXRF) have provided phytoplankton (diatom) ...

A Characterization of the Drivers, Pressures, Ecosystem Functions and Services of Namatala Wetland, Uganda

Namaalwa, S.; dam, A.A. Van; Funk, A.; Ajie, G.S.; Kaggwa, R.C. (Environmental Science & Policy, 2013)

Namatala wetland near the town of Mbale in the Eastern region of Uganda is a papyrus wetland that is subject to conversion for agriculture (mainly rice farming) and pollution by wastewater. The main goal of this study was ...

Uncertainties in Flow-Duration-Frequency Relationships of High and Low Flow Extremes in Lake Victoria Basin

Onyutha, Charles; Willems, Patrick (Water, 2013)

This paper focuses on uncertainty analysis to aid decision making in applications of statistically modeled flow-duration-frequency (FDF) relationships of both daily high and low flows. The analysis is based on 24 selected ...

Effect of polyaluminium chloride water treatment sludge on effluent quality of domestic wastewater treatment

Nansubuga, Irene; Banadda, Noble; Babu, Mohammed; Verstraete, Willy; Wiele, Tom Van de (African Journal of Environmental Science and Technology, 2013)

Water resources degeneration is accelerated by the discharge of untreated wastewater and its byproducts, hence, reuse of these wastes is a major contributor to sustaining fresh water for the coming decades. In this study, ...

Erosion Features on Gravel Roads in Uganda–Formation and Effects

Semwogerere, Twaibu; Lating, Peter O.; Kucel, Samuel B. (International Journal of Applied Physics and Mathematics, 2013)

In the event of erosion flows, the road is one unique surface with various flow and deposition characteristics. Earlier studies focus on erosion features on shores and coasts and sometimes on desert plains as a result of ...

Elephant damage and tree response in restored parts of Kibale National Park, Uganda

Tweheyo, Mnason; Mwesigye Tumusiime, David; Muhairwe, Timothy; Twinomuhangi, Revocatus (International Journal of Biodiversity and Conservation, 2013)

Elephant tree damage is a key factor in conservation and restoration efforts of African rain forests. This study was conducted between June 2009 and February 2010 to examine elephant damage and tree response in restored ...

PCDD/Fs and dioxin-like PCBs in surface sediments from Lake Victoria, East Africa

Ssebugere, Patrick; Kiremire, Bernard T.; Henkelmann, Bernhard; Bernhöft, Silke; Wasswa, John; Kasozi, Gabriel N.; Schramm, Karl-Werner (Science of the total environment, 2013)

Surface sediments (b60 cm) from the Napoleon Gulf and Thurston Bay on the northern shore of Lake Victoria were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like ...

Comparison of extreme weather events and streamflow from drought indices and a hydrological model in River Malaba, Eastern Uganda

Barasa, Bernard,; Kakembo, Vincent,; Mugagga, Frank; Egeru, Anthony (International Journal of Environmental Studies, 2013)

The study examined the applicability of the Combined Drought Index (CDI), Standardized Precipitation Index (SPI) and IHACRES (identification of unit hydrographs and component flows from rainfall, evaporation and streamflow ...
