Maritime international trade and bioinvasions: A three‐year long survey of small mammals in Autonomous Port of Cotonou, Benin

open access: yesJournal of Applied Ecology, Volume 61, Issue 4, Page 669-686, April 2024.
Our results are discussed in terms of ecological processes at play (e.g. interspecific interactions) and operational recommendations (e.g. assessment of proper eradication units, environmental modifications). Abstract International trade has been favouring the dissemination of a wide suite of invasive alien species.

Unravelling the biogeographic determinants of tree growth sensitivity to freeze and drought in Canada's forests

open access: yesJournal of Ecology, Volume 112, Issue 4, Page 848-869, April 2024.
The authors document spatial variations in tree growth sensitivity to freeze and soil moisture and vapour pressure deficits in Canada. They utilize an extensive multi‐species tree‐ring dataset to create maps representing the strength of relationships (t) between tree basal area increments and these factor for the period 1951–2018, with red indicating ...

Filter no more: A modified plankton sampler for rapid in‐water eDNA capture

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 1, Page 60-68, January 2024.
Abstract The combination of an efficient sampling method and high‐throughput analysis of environmental DNA (eDNA) can be a powerful approach for characterising biodiversity across aquatic ecosystems. Plankton net tows are one of the oldest, simplest, and least expensive methods for seston and eDNA collection, but require laborious filtration steps ...
