(The Journal of Animal & Plant Sciences, 2020-10)Weevils (Sitophilus spp) are serious pests that can damage sorghum grains in stores if not controlled. The infestation of sorghum by the pest can cause huge economic loss ranging from 15% to 75% depending on levels of ... -
Sources and hydro-geochemical characteristics of lake Duluti waters, Tanzania
(NM-AIST, 2019-11)Water chemistry, and stable isotopes of oxygen and hydrogen ( 18O and 2H), were used collectively to characterize and quantify Lake Duluti (L. Duluti) – groundwater interaction. Physico-chemical parameters including ... -
Sources of Nitrate in Ground Water Aquifers of the Semiarid Region of Tanzania
(Hindawi, 2021)Nitrate isotopic values are often used as a tool to identify sources of nitrate in order to effectively manage ground water quality. In this study, the concentrations of NO3−, NO2−, and NH4+ from 50 boreholes and shallow ... -
Soybean-Nodulating Rhizobia: Ecology, Characterization, Diversity, and Growth Promoting Functions
(Frontiers in Sustainable Food Systems, 2022-04-14)The worldwide increase in population continues to threaten the sustainability of agricultural systems since agricultural output must be optimized to meet the global rise in food demand. Sub-Saharan Africa (SSA) is among ... -
Spatial and seasonal group size variation of wild mammalian herbivores in multiple use landscapes of the Ngorongoro Conservation Area, Tanzania
(PLOS ONE, 2022-04-19)Group sizes of wild herbivores can be indicators of ecosystem health and proxies for individual and population fitness, particularly in areas where human activities have become increasingly common. We recorded 176 single- ... -
Spatial and temporal distribution of foot-and-mouth disease in four districts situated along the Uganda-Tanzania border: Implications for cross-border efforts in disease control.
(AOSIS, 2018-08-27)Foot-and-mouth disease (FMD) is one of the major trans-boundary animal diseases in East Africa causing economic loss to farmers and other stakeholders in the livestock industry. Foot-and-mouth disease occurs widely in both ... -
Spatial and temporal risk as drivers for adoption of foot and mouth disease vaccination.
(Elsevier Ltd., 2018-08-09)Identifying the drivers of vaccine adoption decisions under varying levels of perceived disease risk and benefit provides insight into what can limit or enhance vaccination uptake. To address the relationship of perceived ... -
Spatial distribution and anthropogenic threats facing medicinal plant Zanthoxylum chalybeum in Simanjiro Area, Northern Tanzania.
(Elsevier, 2020-11)Knob wood (Zanthoxylum chalybeum - Rutaceae) is a medicinal plant species subject to heavy exploitation throughout its areas of occurrence in Sub-Saharan Africa. Despite that the tree has different values as a traditional ... -
Spatial distribution and insecticide susceptibility profile of aedes aegypti mosquitoes in south-eastern, Tanzania
(NM-AIST, 2020-02)Aedes-borne diseases such as dengue and chikungunya constitute constant threats globally. In Tanzania, the main vector species is Aedes aegypti, which is widely distributed in urban areas, but whose ecology remains ... -
Spatial Distribution of Soil Hydrological Properties in the Kilombero Floodplain, Tanzania
(MDPI, 2017-11-30)Analysis and interpretation of soil properties dynamics is a keystone in understanding the hydrologic responses and yield potential of floodplain wetlands. This study characterizes the distribution and spatial trends of ... -
Spatial occurrence and variation of the active pharmaceutical compounds in rivers and groundwater systems in Arusha City, Tanzania
(Elsevier, 2024-06-30)This study investigated the occurrence of 11 pharmaceutical compounds in the rivers and groundwater systems of Arusha City, Tanzania. Each suspected individual residue of active pharmaceutical compounds in water matrices, ... -
Spatial-temporal seasonal and annual rainfall trends and variability assessment in the Pangani Basin, East Africa
(Elsevier, 2024-12)Although in situ rainfall data remains the most accurate, the gauge network density in East Africa is sparse. It lacks continuity, thus making it inadequate to assess the spatial and long-term rainfall trend and variability ... -
