Dynamic in vivo monitoring of granum structural changes of Ctenanthe setosa (Roscoe) Eichler during drought stress and subsequent recovery

Physiologia Plantarum, Volume 177, Issue 1, January/February 2025.
Abstract Investigating the effects of drought stress and subsequent recovery on the structure and function of chloroplasts is essential to understanding how plants adapt to environmental stressors. We investigated Ctenanthe setosa (Roscoe) Eichler, an ornamental plant that can tolerate prolonged drought periods (40 and 49 days of water withdrawal ...

Foliar, nonstructural nectaries in the Marantaceae [PDF]

Canadian Journal of Botany, 1985
Nonstructural, foliar nectaries have been found in two genera of the Marantaceae (Zingiberales). Two nectaries are located on each leaf, at the junction of the leaf sheath and petiole. Externally, they may be readily distinguished from the surrounding tissue by their lighter color and absence of hairs.

Where did they come from, where did they go? Niche conservatism in woody and herbaceous plants and implications for plant‐based paleoclimatic reconstructions

American Journal of Botany, Volume 111, Issue 11, November 2024.
Abstract Premise The ecological conditions that constrain plants to an environmental niche are assumed to be constant through time. While the fossil record has been used previously to test for niche conservatism of woody flowering plants, additional studies are needed in other plant groups especially since they can provide insight with paleoclimatic ...

Using multiscale lidar to determine variation in canopy structure from African forest elephant trails

Remote Sensing in Ecology and Conservation, Volume 10, Issue 5, Page 655-667, October 2024.
Using two scales of airborne lidar, we determined variation in canopy structure from African forest elephant trails. Elephant trails in Lope National Park, Gabon, displayed lower canopy height, canopy cover, and different vertical distribution of plant mass.

Pre‐contact and post‐colonial ecological legacies shape Surinamese rainforests

Ecology, Volume 105, Issue 5, May 2024.
Abstract Disturbances in tropical forests can have long‐lasting ecological impacts, but their manifestations (ecological legacies) in modern forests are uncertain. Many Amazonian forests bear the mark of past soil modifications, species enrichments, and fire events, but the trajectories of ecological legacies from the pre‐contact or post‐colonial ...
