We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time
(John Wiley & Sons, Ltd, 2022-02)
1. Dietary studies in birds of prey involve direct observation and examination of
food remains at resting and nesting sites. Although these methods accurately
identify diet in raptors, they are time-consuming, ...
Towards agricultural sustainability: Status and distribution of copper in Usangu agro-ecosystem, Tanzania
(Elsevier, 2022-02-28)
Despite the positive role of copper (Cu) in plants and animals, excessive amounts have environmental and health
effects. Cu has been excessively accumulating in agricultural soils worldwide due to increased agrochemicals ...
Physicochemical Properties, Fatty Acid Composition, and the Effect of Heating on the Reduction of Cyclopropenoid Fatty Acids on Baobab (Adansonia digitata L.) Crude Seed Oil
(Hindawi, 2020-12-14)
The baobab seed oil has been consumed by humans due to its medicinal and nutrient values for many years. However, the
consumption of baobab seed oil has been perceived by different communities as a health risk caused by ...
Integrating stakeholders' perspectives and spatial modelling to develop scenarios of future land use and land cover change in northern Tanzania.
(PLOS ONE, 2021-02-12)
Rapid rates of land use and land cover change (LULCC) in eastern Africa and limited instances of genuinely equal partnerships involving scientists, communities and decision makers challenge the development of robust pathways ...
Evaluation and Prediction of the Impacts of Land Cover Changes on Hydrological Processes in Data Constrained Southern Slopes of Kilimanjaro, Tanzania
(MDPI, 2021-05-30)
This study provides a detailed assessment of land cover (LC) changes on the water balance components on data constrained Kikafu-Weruweru-Karanga (KWK) watershed, using the integrated approaches of hydrologic modeling and ...
Determining tributary sources of increased sedimentation in East-African Rift Lakes.
(Elsevier B.V., 2020-05-15)
Temporal and spatial sediment dynamics in an East-African Rift Lake (Lake Manyara, Tanzania), and its river inputs, have been evaluated via a combination of sediment tracing and radioactive dating. Changes in sedimentation ...
Tracking animal movements using biomarkers in tail hairs: a novel approach for animal geolocating from sulfur isoscapes.
(Movement Ecology, 2020-09-18)
Background
Current animal tracking studies are most often based on the application of external geolocators such as GPS and radio transmitters. While these technologies provide detailed movement data, they are costly to ...
The effect of land-use systems on greenhouse gas production and crop yields in Wakiso District, Uganda
(Elsevier B.V., 2020-12-16)
Land-use systems are among the leading sources of anthropogenic GHG into the atmosphere; driving global warming, climate change, and associated extreme weather events. To estimate GHGs from the land-use systems, we measured ...
Impact of invasive alien plants Gutenbergia cordifolia and Tagetes minuta on native taxa in the Ngorongoro crater, Tanzania
(Elsevier, 2021-09)
Understanding the ecological impacts of invasive plant species on the native communities and identifying native plant species that co-exist with invasive plants are important for planning the effective control and restoration ...
Toxic metals in East African agro-ecosystems: Key risks for sustainable food production
(Elsevier B.V., 2021-09-15)
The dramatic increase in world population underpins current escalating food demand, which
requires increased productivity in the available arable land through agricultural intensification.
Agricultural intensification ...
