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 ... -
Controlling the abundance of a native invasive plant does not affect species richness or functional diversity of wet grasslands
Krieger, Marie-Therese; Ditton, Julia; Albrecht, Harald; Baaij, Barteline Martina; Kollmann, Johannes; Teixeira, Leonardo Henrique (Peer reviewed; Journal article, 2022-07-17)Aim: In this study, we tested plant community-based management methods to reduce the abundance of the invasive native plant Jacobaea aquatica (marsh ragwort). As J. aquatica mainly occurs in species-rich wet grasslands, ... -
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 ... -
Low precipitation due to climate change consistently reduces multifunctionality of urban grasslands in mesocosms
Rojas-Botero, Sandra; Teixeira, Leonardo H.; Kollmann, Johannes (Peer reviewed; Journal article, 2023-02-03)Urban grasslands are crucial for biodiversity and ecosystem services in cities, while little is known about their multifunctionality under climate change. Thus, we investigated the effects of simulated climate change, i.e., ... -
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 ... -
Phylogenetic distance controls plant growth during early restoration of a semi-arid riparian forest
Teixeira, Leonardo H.; Mazzochini, Guilherme G.; Kollmann, Johannes; Ganade, Gislene (Peer reviewed; Journal article, 2022-10-17)1. Little attention has been paid to phylogenetic diversity during restoration initiatives. Because plant phylogenetic distance can be a surrogate for functional diversity, its consideration could foster the restoration ... -
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 ... -
Reconciling the control of the native invasive Jacobaea aquatica and ecosystem multifunctionality in wet grasslands
Krieger, Marie-Therese; Teixeira, Leonardo H.; Grant, Kerstin; Kollmann, Johannes; Albrecht, Harald (Peer reviewed; Journal article, 2023-03-15)Grasslands are managed to provide multiple goods and services. During recent decades, abandonment of marginal grasslands and intensification of the most productive sites resulted in biodiversity losses and reduced ecosystem ... -
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 ...
