Analysis of Paralogs in Target Enrichment Data Pinpoints Multiple Ancient Polyploidy Events in Alchemilla s.l. (Rosaceae)
Morales-Briones, Diego F.; Gehrke, Berit; Huang, Chien-Hsun; Liston, A; Marx, Hannah; Tank, David; Yang, Ya (Journal article; Peer reviewed, 2021)Target enrichment is becoming increasingly popular for phylogenomic studies. Although baits for enrichment are typically designed to target single-copy genes, paralogs are often recovered with increased sequencing depth, ... -
The enigmatic tropical alpine flora on the African sky islands is young, disturbed, and unsaturated
Kandziora, Martha; Gehrke, Berit; Popp, Magnus; Gizaw, Abel; Brochmann, Christian; Pirie, Michael David (Journal article; Peer reviewed, 2022)Tropical alpine floras are renowned for high endemism, spectacular giant rosette plants testifying to convergent adaptation to harsh climates with nightly frosts, and recruitment dominated by long-distance dispersal from ... -
Gas flaring activity and black carbon emissions in 2017 derived from the Sentinel-3A Sea and Land Surface Temperature Radiometer
Caseiro, Alexandre; Gehrke, Berit; Rücker, Gernot; Leimbach, David; Kaiser, Johannes W. (Journal article; Peer reviewed, 2020)Gas flares are a regionally and globally significant source of atmospheric pollutants. They can be detected by satellite remote sensing. We calculate the global flared gas volume and black carbon emissions in 2017 by ... -
History and evolution of the afroalpine fora: in the footsteps of Olov Hedberg
Brochmann, Christian; Gizaw, Abel; Chala, Desalegn; Kandziora, Martha; Eilu, Gerald; Popp, Magnus; Pirie, Michael David; Gehrke, Berit (Journal article; Peer reviewed, 2021)The monumental work of Olov Hedberg provided deep insights into the spectacular and fragmented tropical alpine flora of the African sky islands. Here we review recent molecular and niche modelling studies and re-examine ... -
Leaps and bounds: geographical and ecological distance constrained the colonisation of the Afrotemperate by Erica
Pirie, Michael David; Kandziora, Martha; Nürk, Nicolai; Le Maitre, Nicholas C.; Mugrabi de Kuppler, Ana; Gehrke, Berit; Oliver, Edward G.H.; Bellstedt, Dirk U. (Peer reviewed; Journal article, 2019-12-05)Background The coincidence of long distance dispersal (LDD) and biome shift is assumed to be the result of a multifaceted interplay between geographical distance and ecological suitability of source and sink areas. Here, ...
