Rangeland forage availability and management in times of drought – A case study of pastoralists in Afar, Ethiopia
Treydte, Anna C.; Schmiedgen, Andrea; Berhane, Gebreyohannes; Tarekegn, Kidanie D. (Elsevier, 2017-04)Many Eastern African rangelands comprise marginal land, where climatic conditions are poor, access rights are increasingly limited, and land degradation is progressing. We conducted participatory land use mapping and ... -
Responses of vegetation and soils to three grazing management regimes in a semi‐arid highland mixed crop‐livestock system
Habtemicael, Mezgebe; Yayneshet, Tesfay; Treydte, Anna C. (John Wiley & Sons, Inc., 2014-10-14)Three grazing regimes [Cut‐and‐carry (CC), seasonal grazing (SG) and continuous grazing (CG)] currently applied in Tigrai region of northern Ethiopia were compared to identify the best grazing management in key native ... -
Savannah trees buffer herbaceous plant biomass against wild and domestic herbivores
Smith, Stuart William; Graae, Bente Jessen; Bukombe, John; Hassan, Shombe Ntaraluka; Lyamuya, Richard Daniel; Mtweve, Philipo Jacob; Treydte, Anna C.; Speed, James David Mervyn (John Wiley & Sons Ltd, 2019-11-30)Questions: Given the growing abundance and dominance of domestic herbivores in savannah ecosystems, can trees maintain plant herbaceous standing biomass under increasing herbivore pressure? Are there differences in the ... -
Seed dispersal potential of Asian elephants
Harich, Franziska K.; Treydte, Anna C.; Roberts, John E.; Savini, Chution; Bauer, Jan Michael; Savini, Tommaso; Ogutu, Joseph O. (Elsevier, 2016-11)Elephants, the largest terrestrial mega-herbivores, play an important ecological role in maintaining forest ecosystem diversity. While several plant species strongly rely on African elephants (Loxodonta africana; L. cyclotis) ... -

Mwendwa, Beatus A.; Kaaya, Omega E.; Kilawe, Charles J.; Treydte, Anna C. (Elsevier B.V., 2020-06-01)Globally, invasive plant species cause negative impacts to human livelihoods and natural ecosystems, particularly in biodiversity hotspots. Maesopsis eminii invasion in Amani Nature Forest Reserve, Tanzania, was considered ... -
Tipping Points in the Supply of Ecosystem Services of a Mountainous Watershed in Southeast Asia
Thellmann, Kevin; Cotter, Marc; Baumgartner, Sabine A.; Treydte, Anna C.; Cadisch, Georg; Asch, Folkard (MDPI, 2018-07-11)Rubber plantations have expanded at an unprecedented rate in Southeast Asia in recent decades. This has led to a substantial decline in the supply of ecosystem services (ESS) and has reduced livelihood options and ... -
Variations in soil properties and native woody plant species abundance under Prosopis juliflora invasion in Afar grazing lands, Ethiopia
Eshete, Abeje; Treydte, Anna C.; Hailemariam, Mengsteab; Solomon, Negasi; Dejene, Tatek; Yilma, Zewdu; Birhane, Emiru (Springer Nature, 2020-06-30)Introduction Pastoralism and agro-pastoralism are the major modes of life in arid and semi-arid rangelands. However, rangeland quality and quantity are rapidly deteriorating due to a number of natural and human-induced ... -
Vigilance Behaviour of Wild Herbivores when Foraging With or Without Livestock
Baltazary, Angelamercy; Roskaft, Eivin; Treydte, Anna C. (Canadian Center of Science and Education, 2019-02-28)In African savannas, and many other rangelands around the world, wildlife presently find themselves interacting with livestock. Many studies have been conducted on vigilance behaviour in response to presence of predators ...
