Markus Fischer Ecology Letters Fast–slow traits predict competition network structure and its response to resources and enemies Quantifying all pairwise interactions in highly diverse ecosystems across contrasting environmental conditions is extremely challenging. However, our results show that this effort is worthwhile to better mechanistically understand how nitrogen addition and pathogen removal, two of the most common drivers of global change, affect the population dynamics of complex communities. Caroline Daniel, Eric Allan, Hugo Saiz PNAS Corn reduces arsenic toxicity in soil When crops grow in arsenic-contaminated soil, this toxic element accumulates in the food chain. A study by the University of Bern and the University of Basel has now discovered a mechanism used by corn plants to reduce arsenic uptake: the key factor is a special substance released into the soil by the roots.

Nature Communications A slow-fast trait continuum at the whole community level in relation to land-use intensification Organisms exhibit a spectrum of functional strategies based on their growth rates, influenced by factors like resource availability and disturbance. This study analyzes trait data from over 2800 taxa across 14 trophic guilds in German grasslands, revealing a community-level 'slow-fast' axis shaped by both direct and trophically mediated responses to environmental drivers. The research further demonstrates that communities with 'fast' traits are linked to accelerated rates of ecosystem functioning, introducing a novel perspective for ecosystem-level functional classification. Caterina Penone, Ralph Bolliger, Markus Fischer, Noëlle V. Schenk Ecology Letters Nitrogen availability and plant functional composition modify biodiversity-multifunctionality relationships The study reveals context-dependent diversity effects on multifunctionality, driven by species pool's functional trait composition. Global change-induced shifts amplify diversity loss impacts on ecosystem functioning, emphasizing the importance of managing functional composition. Overall, these findings underline the need to consider multiple diversity dimensions, and interactions between them and abiotic conditions, to optimise multifunctionality in the context of multiple simultaneous global change factors.

Sandra Brügger 2024/12/07 Dies Academicus 2024 Christoph Schwörer receives SNSF Consolidator Grant The five-year research project titled "Assessing Past and Future Forest Responses to Climate Change Impacts Using Ancient DNA (ARIaDNA)" addresses the urgent ecological challenges posed by climate change and the biodiversity crisis. The ARIaDNA project seeks to uncover how plants have historically adapted to rapid climate warming, with the aim of deepening our understanding of ecosystem responses to climate change and support the development of innovative management strategies. Christoph Schwörer 2024/08/22 Swiss National Science Foundation (SNSF) award The lactonase BxdA mediates metabolic specialisation of maize root bacteria to benzoxazinoids Root exudates contain specialised metabolites that influence the root microbiome of the plant. This study systematically investigated how maize root bacteria metabolize benzoxazinoids, the main bioactive compounds of maize. The authors found that some maize root bacteria can metabolise the benzoxazinoid MBOA to the red degradation product AMPO, whereas root bacteria from other plant species cannot. These maize bacteria carry a unique gene, bxdA, a lactonase, which allows them to metabolise benzoxazinoids and thus specifically adapt to the roots of maize plants.

Responsible forest restoration should avoid converting crucial ecosystems like grasslands, peatlands, and wetlands, that are equally essential. Protecting and restoring forests involves addressing complex social, political, and economic challenges. Land-management policies should prioritize the rights and well-being of local communities and indigenous people. Markus Fischer 2023/11/13 Nature How open were temperate forests in Europe prior to the expansion of Homo sapiens? Past interglacials, i.e. periods with similarly warm climatic conditions than today, offer valuable lessons about the vegetation structure and composition under anthropogenically non-disturbed conditions. Based on the fossil pollen data from 96 sites across Europe, an international team led by researchers of the Aarhus University, Denmark, modelled the vegetation structure of the last interglacial period (129’000 – 116’000 years ago). They conclude that temperate forests were possibly more open than generally thought and discuss the potential role of extinct large herbivores like elephants, rhinoceros, and aurochs. Patrick Schläfli 2023/11/10 Science Advances The global biogeography of tree leaf form and habit Our bottom-up model, derived from empirical inventory data, provides insights into forest composition at the individual tree level. This can help benchmark satellite-derived models of forest structure, ecological models, and conservation efforts by identifying key environmental factors affecting tree demographics in the face of climate change. These insights are crucial for global forest ecosystem conservation and sustainability. Markus Fischer 2023/10/23 Nature Plants Sub-national data is crucial for global mountain biodiversity conservation To assess progress towards internationally agreed biodiversity goals, reports are typically based on entire countries. Researchers from the Global Mountain Biodiversity Assessment at the Institute of Plant Sciences, University of Bern, and their colleagues challenge this country-level approach using the example of how well protected areas cover areas important for mountain biodiversity. They find that country averages deviate quite strongly from values for individual mountain ranges, and conclude that subnational reporting is required to identify areas in need for further protection. They also highlight the need for cross-country conservation initiatives. Jonas Geschke, Mark Snethlage, Markus Fischer, Davnah Urbach 2023/10/12 nature sSustainability In the fast lane thanks to genome recycling Sedimentary analyses show that in just 16,000 years, more than 500 cichlid species, distributed throughout the entire food web, have evolved in Lake Victoria. This explosion of biodiversity was made possible by repeated cycles of fusion and diversification in evolutionary lineages. As pollen finds show, wetland fishes in Lake Victoria thrived when savannah communities dominated the area and lake levels were low, allowing wetland vegetation to spread. However, wetland fish occurrence decreased when the aquatic vegetation declined with the transformation of Lake Victoria into a deep lake, as researchers from the University of Bern (IEE, IPS, GIUB and IfG) and Eawag have described in the “Nature” journal.
