Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

The viscoelastic properties of some Guianese woods [PDF]
, 2009 Samples of tension wood and opposite wood were obtained from four species (#Iyranthera sagotiana#, #Ocotea guyanensis#, #Virola micheli#i, #Sextonia rubra#) growing in the tropical rainforest of French Guiana. Dynamic mechanical analysis was performed in

Biotropica, Volume 58, Issue 2, March 2026.We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Functional Ecology, Volume 40, Issue 2, Page 433-450, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...
