Data from: Resource competition across habitat boundaries asymmetric interactions between benthic and pelagic producers

Christoph Gerald Jäger & Sebastian Diehl
In shallow aquatic systems benthic and pelagic primary producers typically compete for light and nutrients along opposing vertical supply axes pelagic algae shade the benthic habitat; conversely, benthic algae intercept the nutrient flux from the sediment to the pelagic habitat. We present a general framework for analyzing such spatially asymmetric resource competition across habitat boundaries using a mechanistic, dynamical model. We visualize the mechanisms determining the outcome of these cross-habitat interactions using zero-net-growth-isoclines, resource supply...

Data from: Effects of long term differential fertilization on eukaryotic microbial communities in an arable soil: a multiple barcoding approach

Guillaume Lentendu, Tesfaye Wubet, Antonis Chatzinotas, Christian Wilhelm, François Buscot & Martin Schlegel
In order to understand the fine scale effects of changes in nutrient availability on eukaryotic soil microorganisms communities, a multiple barcoding approach was used to analyse soil samples from four different treatments in a long term fertilization experiment. We performed PCR-amplification on soil DNA with primer pairs specifically targeting the 18S rRNA genes of all eukaryotes and three protist groups (Cercozoa, Chrysophyceae-Synurophyceae and Kinetoplastida) as well as the ITS gene of fungi and the 23S...

Data from: Epigenetic variation reflects dynamic habitat conditions in a rare floodplain herb

Benjamin Schulz, Rolf Lutz Eckstein & Walter Durka
Variation of DNA-methylation is thought to play an important role for rapid adjustments of plant populations to dynamic environmental conditions, thus compensating for the relatively slow response time of genetic adaptations. However, genetic and epigenetic variation of wild plant populations has not yet been directly compared in fast changing environments. Here we surveyed populations of Viola elatior from two adjacent habitat types along a successional gradient characterized by strong differences in light availability. Using AFLP...
