Data from: Genetic variation and risks of introgression in the wild Coffea arabica gene pool in south-western Ethiopian montane rainforests

Raf Aerts, Gezahegn Berecha, Pieter Gijbels, Kitessa Hundera, Sabine Van Glabeke, Katrien Vandepitte, Bart Muys, Isabel Roldán-Ruiz & Olivier Honnay
The montane rainforests of SW Ethiopia are the primary centre of diversity of Coffea arabica and the origin of all Arabica coffee cultivated worldwide. This wild gene pool is potentially threatened by forest fragmentation and degradation, and by introgressive hybridization with locally improved coffee varieties. We genotyped 703 coffee shrubs from unmanaged and managed coffee populations, using 24 microsatellite loci. Additionally, we genotyped 90 individuals representing 23 Ethiopian cultivars resistant to coffee berry disease (CBD)....

Data from: Quantifying population divergence on short timescales

Joost A. M. Raeymaekers, Luc Lens, Frederik Van Den Broeck, Stefan Van Dongen & Filip A. M. Volckaert
Quantifying the contribution of the various processes that influence population genetic structure is important, but difficult. One of the reasons is that no single measure appropriately quantifies all aspects of genetic structure. An increasing number of studies is analyzing population structure using the statistic D, which measures genetic differentiation, next to GST, which is the standardized variance in allele frequencies among populations. Few studies have evaluated which statistic is most appropriate in particular situations. In...

Data from: Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid

Katrien Vandepitte, Alessandro S. Gristina, Koen De Hert, Tine Meekers, Isabel Roldán-Ruiz & Olivier Honnay
Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related AFLP genetic variation and fitness of all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex to colonization history. Around 1970, D. incarnata suffered a severe bottleneck...

Data from: Adaptability of large carnivores to changing anthropogenic food sources: diet change of spotted hyena (Crocuta crocuta) during Christian fasting period in northern Ethiopia

Gidey Yirga, Hans H. De Iongh, Herwig Leirs, Kindeya Gebrihiwot, Jozef Deckers & Hans Bauer
Many large carnivores readily use anthropogenic food sources, which often leads to conflict. Spotted hyenas (Crocuta crocuta) around the regional capital Mekelle, northern Ethiopia, feed on waste and to a lesser degree on livestock, but not on natural prey. We investigated the impact on their diet of the 55 day fasting period prescribed by the Ethiopian Orthodox Tewahedo Church, during which the vast majority of people do not consume animal products. We collected spotted hyena...

Data from: The role of selection in driving landscape genomic structure of the waterflea Daphnia magna

Luisa Orsini, Joachim Mergeay, Joost Vanoverbeke & Luc De Meester
The combined analysis of neutral and adaptive genetic variation is crucial to reconstruct the processes driving population genetic structure of natural populations. However, such combined analysis is challenging because of the complex interaction among neutral and selective processes in the landscape. Overcoming this level of complexity requires an unbiased search for the evidence of selection in the genomes of populations sampled from their natural habitats and the identification of demographic processes that lead to present-day...
