Journal ArticleDOI
Genetic consequences of Pleistocene range shifts: contrast between the Arctic, the Alps and the East African mountains
Dorothee Ehrich,Myriam Gaudeul,Adane Assefa,Adane Assefa,Marcus A. Koch,Klaus Mummenhoff,Sileshi Nemomissa,Christian Brochmann +7 more
TL;DR: The genetic structure observed corresponded to the expectations based on the environmental history of the different regions, and the fragmented structure in the European and African mountains indicated that A. alpina disperses little among established populations.
Journal ArticleDOI
Some biological characteristics that foster the invasion of Prosopis juliflora (Sw.) DC. at Middle Awash Rift Valley Area, north-eastern Ethiopia
TL;DR: The results clearly demonstrated that Prosopis is equipped with a number of biological characteristics that foster its rapid invasion of new areas and is a powerful noxious invader as can be evidenced from its rampant invasion in the study site and elsewhere in the tropics.
Journal ArticleDOI
Distribution of arbuscular mycorrhizal fungi spores in soils of smallholder agroforestry and monocultural coffee systems in southwestern Ethiopia
TL;DR: Agroforestry practices including the use of leguminous shade trees effectively maintained AMF numbers in soils even at depth compared with unshaded coffee plants (monocultures).
Journal ArticleDOI
Pleistocene colonization of afro-alpine ‘sky islands’ by the arctic-alpine Arabis alpina
TL;DR: The observed pattern is consistent with isolation of the African lineage in at least two interglacial refugia, located on separated highlands, followed by range expansion in cooler period(s), when the afro-alpine habitat extended further down the mountains.
Journal ArticleDOI
Phylogeography and conservation genetics of a giant lobelia (Lobelia giberroa) in Ethiopian and Tropical East African mountains.
Mulugeta Kebede,Mulugeta Kebede,Dorothee Ehrich,Pierre Taberlet,Sileshi Nemomissa,Christian Brochmann +5 more
TL;DR: Genetic diversity was lower in Ethiopia than in the other two main groups, possibly due to an ancient founder effect when Ethiopia was colonized from the south, and this pattern indicates gradual expansion and supports the montane forest bridge hypothesis.
