Diatoms are frequently used as indicators of eutrophication in temperate systems, but little is known about their application to impacted African tropical systems. Five streams located within Gombe Stream National Park and five streams supporting human settlements draining into Lake Tanganyika, East Africa, were investigated for species composition,(More)
Geochemical signals of bulk sedimentary organic matter from three cores from Lake Tanganyika provided information about both internal processes and terrestrial inputs to the lake. Indications of land use change were detected in the geochemical records of the watersheds, and the timing of these changes was consistent with historical records of population(More)
We investigated paleolimnological records from a series of river deltas around the northeastern rim of Lake Tanganyika, East Africa (Tanzania and Burundi) in order to understand the history of anthropogenic activity in the lake’s catchment over the last several centuries, and to determine the impact of these activities on the biodiversity of littoral and(More)
Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support(More)
In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean= 0.34°C decade ) between 1985 and 2009. Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, leading to(More)
We investigated the feasibility of using genetic techniques to census pine marten (Martes martes) populations by genotyping non-invasively collected samples (plucked hair and scats), with particular reference to the genetically depauperate Irish population. Novel real-time polymerase chain reaction methods were developed for species and sex identification,(More)
The nitrile metabolising strains AJ270, AJ300 and AJ115 were isolated from the same location. The strains have very similar nitrile metabolising profiles. Sequencing of the 16S rRNA gene indicates that strains AJ270 and AJ300 are novel strains of Rhodococcus erythropolis while strain AJ115 is a novel Microbacterium strain very closely related to(More)
Population growth and watershed deforestation in northwestern Tanzania threaten the biodiversity of Lake Tanganyika through erosion and habitat degradation. We used cores collected offshore from Gombe Stream National Park and a deforested watershed to reconstruct how land-use changes in the Gombe Stream area since A.D. 1750 have affected lake biodiversity.(More)
O’Reilly, Catherine M., Kevin E. Fogarty, Robert M. Drummond, Richard A. Tuft, and John V. Walsh, Jr. Spontaneous mitochondrial depolarizations are independent of SR Ca release. Am J Physiol Cell Physiol 286: C1139–C1151, 2004. First published January 7, 2004; 10.1152/ajpcell.00371.2003.—The mitochondrial membrane potential ( m) underlies many mitochondrial(More)
We investigated the origins and persistence of European pine marten (Martes martes) populations across the British Isles by identifying mitochondrial DNA (mtDNA) sequences from contemporary populations (sampled since 1981) and comparing these with those of older ‘historical’ museum specimens (pre-1981) originally collected from the same geographic areas.(More)
