Invasive spread in meta-food-webs depends on landscape structure, fertilization and species characteristics

Johanna Häussler, Remo Ryser & Ulrich Brose
Land use change and biological invasions collectively threaten biodiversity. Yet, few studies have addressed how altering the landscape structure and nutrient supply can promote biological invasions and particularly invasive spread (the spread of an invader from the place of introduction), or asked whether and how these factors interact with biotic interactions and invader properties. We here bridge this knowledge gap by providing a holistic network-based approach. Our approach combines a trophic network model with a...

Agriculture causes homogenization of plant-feeding nematode communities at the regional scale

Antonio Archidona-Yuste, Thorsten Wiegand, Nico Eisenhauer, Carolina Cantalapiedra-Navarrete, Juan E. Palomares-Rius & Pablo Castillo
1. An emerging research line in conservation ecology addresses how environmental change drivers may cause the biotic homogenization of ecological communities by shifts in species diversity and community composition. While the drivers have been explored in unmanaged ecosystems and managed agricultural systems, this issue has received limited attention in regards to a key soil bioindicator organisms, soil nematodes. 2. In this study, we evaluated the effect of land-use change and intensification on the diversity of...

Data for: Plant diversity effects on herbivory are related to soil biodiversity and plant chemistry

Christian Ristok, Alexander Weinhold, Marcel Ciobanu, Yvonne Poeschl, Christiane Roscher, Fredd Vergara, Nico Eisenhauer & Nicole Van Dam
Insect herbivory is a key process in ecosystem functioning. While theory predicts that plant diversity modulates herbivory, the mechanistic links remain unclear. We postulated that the plant metabolome mechanistically links plant diversity and herbivory. In late summer and in spring, we assessed individual plant aboveground herbivory rates and metabolomes of seven plant species in experimental plant communities varying in plant species diversity and resource acquisition strategies. In the same communities, we also measured plant individual...

Plant history and soil history jointly influence the selection environment for plant species in a long-term grassland biodiversity experiment

Peter Dietrich, Nico Eisenhauer, Peter Otto & Christiane Roscher
Long-term biodiversity experiments have shown increasing strengths of biodiversity effects on plant productivity over time. However, little is known about rapid evolutionary processes in response to plant community diversity, which could contribute to explaining the strengthening positive relationship. To address this issue, we performed a transplant experiment with offspring of seeds collected from four grass species in a 14-year old biodiversity experiment (Jena Experiment). We used two- and six-species communities and removed the vegetation of...
