Data from: Interspecific hybridisation and interaction with cultivars affect the genetic variation of Ulmus minor and U. glabra in Flanders

Karen Cox, An Vanden Broeck, Kristine Vander Mijnsbrugge, Joukje Buiteveld, Eric Collin, Hans M. Heybroek & Joachim Mergeay
Interspecific hybridisation and gene flow from cultivated plants may have profound effects on the evolution of wild species. Considering the cultural history and past use of U. minor and U. glabra trees in Flanders (northern Belgium), we investigated the extent of human impact on the genetic variation of the remaining, supposedly indigenous elm populations. We therefore examined the rate of interspecific hybridisation, which is expected to be higher under human influence, the occurrence of clones...

Data from: Landscape genomics and a common garden trial reveal adaptive differentiation to temperature across Europe in the tree species Alnus glutinosa

The adaptive potential of tree species to cope with climate change has important ecological and economic implications. Many temperate tree species experience a wide range of environmental conditions, suggesting high adaptability to new environmental conditions. We investigated adaptation to regional climate in the drought-sensitive tree species Alnus glutinosa (Black alder), using a complementary approach that integrates genomic, phenotypic and landscape data. A total of 24 European populations were studied in a common garden and through...

Data from: High levels of effective long-distance dispersal may blur ecotypic divergence in a rare terrestrial orchid

Background: Gene flow and adaptive divergence are key aspects of metapopulation dynamics and ecological speciation. Long-distance dispersal is hard to detect and few studies estimate dispersal in combination with adaptive divergence. The aim of this study was to investigate effective long-distance dispersal and adaptive divergence in the fen orchid (Liparis loeselii (L.) Rich.). We used amplified fragment length polymorphism (AFLP)-based assignment tests to quantify effective long-distance dispersal at two different regions in Northwest Europe. In...

Data from: Rapid genetic adaptation precedes the spread of an exotic plant species

Katrien Vandepitte, Tim De Meyer, Kenny Helsen, Kasper Van Acker, Isabel Roldán-Ruiz, Joachim Mergeay & Olivier Honnay
Human activities have increasingly introduced plant species far outside their native ranges under environmental conditions that can strongly differ from those originally met. Therefore, before spreading, and potentially causing ecological and economical damage, non native species may rapidly evolve. Evidence of genetically based adaptation during the process of becoming invasive is very scant however, which is due to the lack of knowledge regarding the historical genetic makeup of the introduced populations and the lack of...

Data from: Re-visiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulations

Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples...

Data from: Local and regional founder effects in lake zooplankton persist after thousands of years despite high dispersal potential

Marc Ventura, Adam Petrusek, Alexandre Miró, Eva Hamrová, Danilo Buñay, Luc De Meester & Joachim Mergeay
We reconstructed the genetic structure of a planktonic crustacean Daphnia longispina living in high mountain lakes and ponds in the Pyrenees to investigate whether it was shaped by persistent founder effects originating shortly after the last glacial maximum or by ongoing dispersal and effective migration (gene flow). We found that the genetic structure can largely be explained by a single colonization event following gradual deglaciation of the Pyrenees c. 10-15 000 years ago. Nuclear genetic...

Data from: Assessing the impact of beach nourishment on the intertidal food web through the development of a mechanistic-envelope model

Sarah Vanden Eede, Joke Van Tomme, Charlotte De Busschere, Martijn Vandegehuchte, Koen Sabbe, Eric W. M. Stienen, Steven Degraer, Magda Vincx, Dries Bonte, Martijn L. Vandegehuchte & Eric W.M. Stienen
Beach nourishment, the placement of sand onto a sediment-starved stretch of coast, is widely applied as a soft coastal protection measure because of its reduced ecological impact relative to hard coastal protection. In order to predict effects on the intertidal sandy beach ecosystem, we developed a simulation model that integrates species envelope-based projections for the dominant macrobenthos species and mechanistic food web modules for higher trophic levels. Species envelopes were estimated by using Bayesian inference...
