Discreet but diverse and specific: Determining plant‐herbivore interactions across a species‐rich plant family in a tropical rain forest

Biotropica, Volume 57, Issue 1, January 2025.
We conducted a year‐long study in Ecuador's Yasuní National Park, focusing on nine understory Annonaceae species to investigate herbivory patterns and herbivore‐host associations. Our findings revealed significant temporal fluctuations in leaf damage, with Anaxagorea brevipes and Unonopsis veneficiorum experiencing higher herbivore pressure, and ...

High tolerance to zinc but no evidence for local adaptation in the aquatic plant Lemna minor

Nordic Journal of Botany, Volume 2024, Issue 7, July 2024.
Duckweeds are a widely distributed and economically important aquatic plant family that have high potential for phytoremediation of polluted water bodies. We collected four ecotypes of the common duckweed Lemna minor from the four corners of Switzerland and assessed how their home versus away environments influenced their growth.
