Article
Full-text available
Experiments under natural conditions are becoming increasingly important to investigate the impacts of global change on biodiversity and ecosystem functioning, but field experiments are not always feasible. Climate or biodiversity chamber experiments can be an alternative, which, however, require large amounts of soil substrate. If only low amounts...
Article
Full-text available
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 transpla...
Article
Full-text available
Diversity loss has been shown to change the soil community; however, little is known about long-term consequences and underlying mechanisms. Here, we investigated how nematode communities are affected by plant species richness and whether this is driven by resource quantity or quality in 15-year-old plant communities of a long-term grassland biodiv...
Article
Full-text available
Global change has dramatic impacts on grassland diversity. However, little is known about how fast species can adapt to diversity loss and how this affects their responses to global change. Here, we performed a common garden experiment testing whether plant responses to global change are influenced by their selection history and the conditioning hi...
Article
Full-text available
Tree species are known to predominantly interact either with arbuscular mycorrhizal (AM) or ectomycorrhizal (EM) fungi. However, there is a knowledge gap whether these mycorrhizae differently influence biodiversity-ecosystem functioning (BEF) relationships and whether a combination of both can increase community productivity. In 2015, we establishe...
Article
Full-text available
Aim: Palaeoclimate legacies have been reported to influence microbial communities and carbon (C) stocks even after thousands of years. However, the direct and indirect influences of climate legacies on microbial C processes remain poorly understood and thus limit our capacity to predict how climate legacies regulate C cycling. Here, we conducted mi...

Global change has dramatic impacts on grassland diversity. However, little is known about how fast species can adapt to these changes and how this affects their responses to global change.

Article
Aims Intensive land management practices can compromise soil biodiversity, thus jeopardizing long-term soil productivity. Arbuscular mycorrhizal fungi (AMF) play a pivotal role in promoting soil productivity through obligate symbiotic associations with plants. However, it is not clear how properties of plant communities, especially species richness...

Video abstract: https://youtu.be/HhyGXkz6QGY Knowledge from agriculture and ecological field studies suggests that plant monocultures lose productivity over time, but the drivers underlying the long‐term performance of monocultures of grassland species are not completely understood. We examined the performance of 60 grassland species growing in m...
Article
Full-text available
One of the unifying goals of ecology is understanding the mechanisms that drive ecological patterns. For any particular observed pattern, ecologists have proposed varied mechanistic models. However, in spite of their differences, all of these mechanistic models rely on either abiotic conditions or biotic conditions, our “ecological first principles...

Aims Recent studies in experimental grasslands indicated that declining plant species diversity negatively affects soil microbial communities. Here, we assessed if plant diversity effects also occur in “real-world” grasslands. Methods We studied the influence of fertilization, soil, and plant community characteristics on soil microbial activity (m...

Plant diversity is dramatically decreasing due to the impact of human-made global change. The loss of plant species has a strong impact on environmental conditions and ecosystem functioning caused by the loss of essential interactions among plants and between plants and soil biota. Resultantly, plant species loss can change the selection environment and thus micro-evolutionary trajectories and eco-evolutionary feedbacks of the persistent plant species. However, there is a lack of knowledge, how rapid and pervasive changes in microevolution are in response to plant species loss. Moreover, it is not known whether these potential shifts in microevolution affect the response of plants to global change, which is an important issue, because the change in response could further accelerate global change becoming a feedback loop. To test this, I conducted three subsequent studies, which investigated the single steps of the potential feedback loop. The investigations and experiments of this dissertation were performed in 14-year old plant communities of a long-term biodiversity experiment in Germany (Jena Experiment), which differed in plant species richness.
