Does economic optimisation explain LAI and leaf trait distributions across an Amazon soil moisture gradient?

open access: yesGlobal Change Biology, Volume 27, Issue 3, Page 587-605, February 2021., 2021
We test if the trade‐offs between leaf carbon costs (via growth and maintenance) and gains (via photosynthesis) explain differences in canopy dynamics across an Amazon moisture stress gradient. We show that observed mean leaf area index (LAI) and LAI seasonality across the gradient are consistent with optimality‐based predictions.

Identifying tree roots in the caves of Quintana Roo, Mexico as a step toward ecological insights and improved conservation

open access: yesPLANTS, PEOPLE, PLANET, Volume 2, Issue 2, Page 133-139, March 2020., 2020
Caves in Quintana Roo, Mexico are known for spectacular calcite formations, blue water, and their significance in Mayan culture. A fascinating feature of these caves is the tree roots that emerge from ceilings, walls, and floors. Little is known about these incredible natural structures which form a key part of the ecosystem, linking to the forests ...

Diversity of fungal endophytes from the medicinal plant Dendropanax arboreus in a protected area of Mexico

open access: yesAnnals of Microbiology, 2015
With the aim of studying the biodiversity and the biotechnological potential of endophytic fungi associated with the medicinal plant Dendropanax arboreus, 45 fungal isolates were recovered from ten plants grown at the “El Cielo” Biosphere Reserve, Mexico. Based on the sequence analysis of internal transcribed spacer (ITS) regions and the observation of

On the Significance of Leaf Sides in Automatic Leaf-based Plant Species Identification [PDF]

open access: yes, 2016
Because the front side of a leaf and the underside are functionally very different – the former captures sunlight to produce photosynthesis and the latter absorbs carbon dioxide and releases oxygen and vapor – they typically have different visual ...
