A high‐resolution model of the grapevine leaf morphospace predicts synthetic leaves

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 133-146, January 2025.
Grapevine leaves are emblematic of the strong visual associations people make with plants. Leaf shape is immediately recognizable at a glance, and therefore, this is used to distinguish grape varieties. In an era of computationally enabled machine learning–derived representations of reality, we can revisit how we view and use the shapes and forms that ...

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

open access: yesBiotropica, 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 ...

Plant‐based meat analogues marketed in Catalonia: analysis of contaminants, essential elements, microbiological and physicochemical status, dietary intake estimation and health risk assessment

open access: yesFood Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract The latest barometer of food safety in Catalonia conducted by the Catalan Food Safety Agency (ACSA for its initials in Catalan) in 2021 shows that 28.7% of the population consumes meat analogues (substitutes). The main reasons for consuming this type of food are animal welfare, followed by environmental and health reasons.

Tropical forest above‐ground productivity is maintained by nutrients cycled in litter

open access: yesJournal of Ecology, Volume 112, Issue 4, Page 690-700, April 2024.
The maintenance of highly productive lowland tropical forests on infertile soils is often attributed to nutrient cycling via litterfall. Almost 40 years after this theory was first proposed, our large‐scale field experiment demonstrates that tree growth and litter production decline in response to long‐term litter removal, providing the first empirical

Trials and tribulations of Neotropical plant taxonomy: Pace of tree species description

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 2, Page 515-527, March 2024.
Given the current unprecedented concerns for global biodiversity loss, it is critical to identify best practices for describing new species more efficiently so we can complete the inventory of the Neotropical flora and implement appropriate conservation strategies in a timely manner.
