Sequential invasions by fruit flies (Diptera: Tephritidae) in Pacific and Indian Ocean islands: A systematic review [PDF]

Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022
We gathered observations of invasions by polyphagous tephritids in islands. All invasion links were directional, i.e., they involved a series of invasions by invaders that were closely related to a resident species but were increasingly more competitive. These sequential establishments of species are driven by interspecific competition between resident

Tri‐trophic interactions among Fopius arisanus, Tephritid species and host plants suggest apparent competition [PDF]

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
Our main objective was to characterize the tri‐trophic interactions between Fopius arisanus, fruit fly and host plant species by long‐term field database and laboratory assays. Results suggest a possible existence of apparent competition between Bactrocera dorsalis and Bactrocera zonata via F. arisanus.

Comparative adult preference–larval performance relationship between a specialist and a generalist tephritid: Implication for predicting field host‐range [PDF]

Ecology and Evolution, Volume 14, Issue 8, August 2024.
The aim of our study was to compare the larval performance and adult preference of a highly generalist species, Bactrocera tryoni, and a highly specialist species, B. umbrosa. Our data comfort the hypothesis that the preference–performance relationship is tighter in specialists than in generalist species.

Effects of canopy connectivity on the arboreal ant community in coffee shade trees

Biotropica, Volume 55, Issue 6, Page 1106-1113, November 2023., 2023
We manipulated connectivity between the crowns of large shade trees and found more species and increased compositional similarity in connected crowns. Differences in connectivity in the upper canopy may be important in structuring differences in ant communities in shaded agricultural systems and unmanaged forests.

Agroecological farming, flowering phenology and the pollinator–herbivore–parasitoid nexus regulate non‐crop plant reproduction

Journal of Applied Ecology, Volume 59, Issue 8, Page 2046-2058, August 2022., 2022
Agroecological management produced spatial and temporal gradients in crop and non‐crop floral resources that interacted to modify pollinator or seed herbivore–parasitoid interactions and Cyanus segetum and Centaurea jacea seed set. The degree of phenological overlap between C. segetum and C.

Implementation of Eco‐schemes in Fifteen European Union Member States Mise en œuvre des éco‐régimes dans quinze États membres de l'Union européenne Umsetzung der Eco‐Schemes in fünfzehn Mitgliedstaaten der Europäischen Union

EuroChoices, Volume 21, Issue 2, Page 19-27, August 2022., 2022
Summary Eco‐schemes are set to play an important role in the European Union’s Common Agricultural Policy (CAP) post‐2022 for the delivery of environmental and climate benefits and enhanced animal welfare. This article surveys current plans for the design of eco‐schemes in fifteen European Union Member States.

Niche shift of tephritid species after the Oriental fruit fly (Bactrocera dorsalis) invasion in La Réunion

Diversity and Distributions, Volume 27, Issue 1, Page 109-129, January 2021., 2021
Abstract Aim In a context of successive fruit fly invasions (Tephritidae), this study investigated how the top invader, Bactrocera dorsalis, displaced established fruit fly populations. We focused, particularly, on how this invasion impacted the host range and climatic niche of each resident species. Location La Réunion, France, Indian Ocean.

Leben und Überleben im Boden

Biologie in unserer Zeit, Volume 50, Issue 6, Page 424-432, December 2020., 2020
Mit Myxococcus xanthus wurde 2020 ein Bodenbakterium zur Mikrobe des Jahres gewählt. Myxobakterien produzieren eine Vielzahl an biologisch aktiven Sekundärmetaboliten und dienen als Modellorganismen zur Erforschung von Zell‐Zell‐Kommunikation und Zelldifferenzierung. Zusammenfassung Myxobakterien wie Myxococcus xanthus sind ungewöhnliche Bodenbakterien,
