Comparison of the effects of a broad-spectrum herbicide and a bio-herbicide on insect flower visitation in the Serengeti ecosystem, Tanzania
(Elsevier, 2021-12)
The functional role of insect visitors on flowering plants is crucial to both natural and agricultural ecosystems. While, few studies have addressed the impact of invasive plant species on insect visitors, even less is ...
Balancing Bees and Livestock: Pastoralist Knowledge, Perceptions and Implications for Pollinator Conservation in Rangelands, Northern Tanzania
(SAGE journal, 2021-01-01)
Insect pollinators provide numerous ecosystem services that support other living organisms. While pollinators play a large
role in cropping systems, little is known about their presence and function in rangeland ecosystems, ...
The Potential of Oyster Nuts (Telfairia pedata) for Environmental Conservation and Food Security in Tanzania: A Review
(Springer Nature, 2021-07-29)
The oyster nut, Telfairia pedata, a vine that grows on tall trees, is native only to Tanzania and Uganda. Its nuts are valued by the local population mainly because of their lactogenic properties. Despite its nutritional, ...
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- ...
Rainfall variability and socio‑economic constraints on livestock production in the Ngorongoro Conservation Area, Tanzania
(Springer Nature Switzerland AG., 2021-01-12)
Rainfall variability is of great importance in East Africa, where small-scale farmers and pastoralists dominate. Their livestock production activities are heavily dependent on rainfall. We assessed pastoralist perceptions ...
Traditional rangeland management can conserve insect pollinators in a semi-arid rangeland, northern Tanzania
(Elsevier, 2021-11)
Globally, pollinators are threatened by land-use changes, including habitat degradation. East African rangelands are under pressure due to livestock population increase and overutilization, which lead to degradation of ...
Species-specific responses of “Critically Endangered” and “Least Concern” Aloe seed germination to environmental conditions in Tanzania
(Elsevier B.V., 2020-12)
The majority of Aloe species are threatened by anthropogenic activities, trade, and the effects of
climate change, but little is known on seed biology and appropriate conservation measures.
Hence, understanding the ...
Fatty Acid Contents and Stability of Oyster Nut Oil (Telfairia pedata) Compared to Flaxseed and Sunflower Oil
(Hindawi, 2021-11-21)
The selection of healthy fats for consumption is important. Linoleic acid (LA) (omega-6) and alpha-linolenic acid (ALA) (omega-3) are essential polyunsaturated fatty acids required for the maintenance of good health; ...
Environmental factors and non-chemical methods to suppress growth of the invasive plant Gutenbergia cordifolia
(Elsevier, 2023-08-01)
Little is known about preferred environmental conditions and non-chemical control of invasive Gutenbergia cordifolia. We assessed the effects of different A. annua crude extract concentrations, synthetic herbicide (glyphosate), ...
Retaliatory killing negatively affects African lion (Panthera leo) male coalitions in the Tarangire-Manyara Ecosystem, Tanzania
(PLOS ONE, 2022-08-31)
In landscapes where people and lions coexist, conflicts are common due to livestock preda-
tion and threats to human safety. Retaliatory lion killing by humans is often a consequence
and is one of the leading causes of ...
