Are local plants the best for ecosystem restoration? It depends on how you analyze the data
Bucharova, Anna; Durka, Walter; Hölzel, Norbert; Kollmann, Johannes; Michalski, Stefan; Bossdorf, Oliver (Journal article; Peer reviewed, 2017-11-06)One of the key questions in ecosystem restoration is the choice of the seed material for restoring plant communities. The most common strategy is to use local seed sources, based on the argument that many plants are locally ... -
Competition components along productivity gradients – revisiting a classic dispute in ecology
Sauter, Fabian; Albrecht, Harald; Kollmann, Johannes; Lang, Marion (Peer reviewed; Journal article, 2021-06-04)Competition is ubiquitous in plant communities with various effects on plant fitness and community structure. A long-standing debate about different approaches to explain competition is the controversy between David Tilman ... -
Competitive trait hierarchies of native communities and invasive propagule pressure consistently predict invasion success during grassland establishment
Rojas-Botero, Sandra; Kollmann, Johannes; Teixeira, Leonardo H. (Peer reviewed; Journal article, 2021-09-21)Invasive non-native plants challenge ecosystems restoration, and understanding the factors that determine the establishment of invasive plants is crucial to improve restoration outcomes. However, the drivers of invasibility ... -
Functional diversity and invasive species influence soil fertility in experimental grasslands
Teixeira, Leonardo H.; Yannelli, Florencia A.; Ganade, Gislene; Kollmann, Johannes (Peer reviewed; Journal article, 2020-01-01)Ecosystem properties can be positively affected by plant functional diversity and compromised by invasive alien plants. We performed a community assembly study in mesocosms manipulating different functional diversity levels ... -
Impacts of roads on bird species richness: A meta-analysis considering road types, habitats and feeding guilds
Kroeger, Svenja; Hanslin, Hans Martin; Lennartsson, Tommy; D'Amico, Marcello; Kollmann, Johannes; Fischer, Christina; Albertsen, Elena; Speed, James David Mervyn (Peer reviewed; Journal article, 2021-03-15)Roadsides can harbour remarkable biodiversity; thus, they are increasingly considered as habitats with potential for conservation value. To improve construction and management of roadside habitats with positive effects on ... -
Moving Away From Limiting Similarity During Restoration: Timing of Arrival and Native Biomass Are Better Proxies of Invasion Suppression in Grassland Communities
Yannelli, Florencia A.; MacLaren, Chloe; Kollmann, Johannes (Peer reviewed; Journal article, 2020-07-17)A challenge in many restoration projects, in particular when establishing de novo communities, is the arrival and later dominance of invasive alien plants. This could potentially be avoided by designing invasion-resistant ... -
Positive responses of coastal dune plants to soil conditioning by the invasive Lupinus nootkatensis
Hanslin, Hans Martin; Kollmann, Johannes (Journal article; Peer reviewed, 2016-08-26)Invasive nitrogen-fixing plants drive vegetation dynamics and may cause irreversible changes in nutrient-limited ecosystems through increased soil resources. We studied how soil conditioning by the invasive alien Lupinus ... -
Suppression of an invasive native plant species by designed grassland communities
Möhrle, Kathrin; Reyes-Aldana, Hugo E.; Kollmann, Johannes; Teixeira, Leonardo H. (Peer reviewed; Journal article, 2021-04-15)Grassland biodiversity is declining due to climatic change, land-use intensification, and establishment of invasive plant species. Excluding or suppressing invasive species is a challenge for grassland management. An example ...
