Retaliatory killing negatively affects African lion (Panthera leo) male coalitions in the Tarangire-Manyara Ecosystem, Tanzania
Felix, Nancy; Kissui, Bernard; Munishi, Linus; Treydte, Anna (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 ... -
A Socio-Ecological Approach to Understanding How Land Use Challenges Human-Elephant Coexistence in Northern Tanzania
Sanare, John; Valli, Davide; Leweri, Cecilia; Glatzer, Gregory; Fishlock, Vicki; Treydte, Anna (MDPI, 2022-06-24)A globally rapid land use/land cover change (LULC) in human-transformed landscapes alters the interface of human-wildlife interactions due to shifting socio-ecological and environmental pressures. Understanding these shifts ... -
Spatial and seasonal group size variation of wild mammalian herbivores in multiple use landscapes of the Ngorongoro Conservation Area, Tanzania
Leweri, Cecilia; Bartzke, Gundula; Msuha, Maurus; Treydte, Anna (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- ... -
Spatio-Temporal Patterns of Increasing Illegal Livestock Grazing over Three Decades at Moyowosi Kigosi Game Reserve, Tanzania
Musika, Nyangabo; Wakibara, James; Ndakidemi, Patrick; Treydte, Anna (MDPI, 2021-12-02)The global increase of livestock has caused illegal intrusion of livestock into protected areas. Until now, hotspot areas of illegal grazing have rarely been mapped, long-term monitoring data are missing, and little is ... -
Species-specific responses of “Critically Endangered” and “Least Concern” Aloe seed germination to environmental conditions in Tanzania
Abihudi, Siri; Venkataramana, Pavithravani; de Boer, Hugo; Treydte, Anna (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 ... -
