We focused both on methodological issues, showing the growing importance of nondestructive high resolution approaches (XRF core-scanner) as well as progresses in the understanding of processes leading to the creation of an “erosion signal” in lakes. We distinguish “continuous records” from “event-records”. Both provide complementary information but need to be studied with different approaches. Continuous regionally-relevant records proved to be particularly pertinent to document regional erosion patterns throughout the Holocene, in particular applying the source to sink approach. Event-based approaches demonstrated and took advantage of the strong non-linearity of sediment transport in high altitude catchment areas. This led to flood frequency and intensity reconstructions, highlighting the influence of climate change upon flood dynamics in the mountain.

Non-Native, Non-Naturalised Plants Suffer Less Herbivory Than Native Plants Across European Botanical Gardens / Katy Ivison in Diversity and Distributions, 30 (12) (2024) 

Public Citation [article]  inDiversity and Distributions > 30 (12) (2024) . - e13938 Titre : Non-Native, Non-Naturalised Plants Suffer Less Herbivory Than Native Plants Across European Botanical Gardens Type de document : Imprimé Auteurs : Katy Ivison ; Mark van Kleunen (1973-) ; James M.D. Speed ; Vibekke Vange ; Sonia Pujara ; Steffen Boch ; Dirk Enters ; Quentin Groom ; Zdeněk Janovský ; Jonathan M. Jeschke ; Jasmin Joshi ; Annette Kolb ; Johannes Kollmann (1963-) ; Tomáš Koubek ; Tristan Lemke ; Diethart Matthies ; Jana Raabova ; Katja Tielbörger ; Wayne Dawson Année de publication : 2024 Article en page(s) : e13938 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Aim: The enemy release hypothesis states that the invasion success of non-native species is partly due to their escape from natural enemies, e.g., herbivores. Large-scale studies of herbivory using multiple species across multiple sites are needed to test the generality of herbivory release in non-native plants. Location: Europe. Methods: We carried out leaf-herbivory surveys from 2007 to 2021 in 15 botanical gardens ranging in latitude from 47°N (Switzerland) to 63°N (Norway) to investigate how herbivory levels differed between (i) native and non-native species, and (ii) native and non-naturalised or naturalised species. Results: Overall, we found that herbivory levels were lower on non-native than native species. In addition, we found that non-naturalised plants suffered less herbivory than natives and that naturalised plants showed similar levels of herbivory to native plants. Main Conclusions: We find broad support for lower herbivory of non-native plant species compared to natives. However, the stronger reduction in herbivory for non-naturalised plants suggests that herbivore release may be transient and less pronounced for naturalised non-native species that have become abundant and integrated into resident communities. This has implications for the management of naturalised non-native plants, which are performing well in their non-native ranges despite suffering comparable herbivory levels to native species.
