Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

Functional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...

Alterações morfológicas foliares em abacaxizeiros cv. IAC "Gomo-de-mel" micropropagados e aclimatizados em diferentes condições de luminosidade Morphological alterations in leave of micropropagated pineapple plants cv. IAC "Gomo-de-mel" acclimatizated in different conditions of luminosity

Acta Botânica Brasílica, 2009
Plantas micropropagadas geralmente apresentam dificuldades de adaptação ao meio ex vitro, sendo muitas vezes submetidas a processos de rustificação para minimizar os impactos decorrentes da mudança de ambiente.

Effects of Long‐Term Nutrient Addition on Leaf Metabolites, Herbivory, and Mycorrhizal Spores Associated With a Savannah Woody Species

Austral Ecology, Volume 50, Issue 11, November 2025.
ABSTRACT Given the importance of soil conditions for ecosystem functioning, fertilisation experiments are a valuable tool for assessing how systems respond to changes in soil properties. However, the effects of changes in nutrient availability on multitrophic interactions in savannah ecosystems of the Brazilian Cerrado are still scarce. We investigated

Produção, composição da uva e teores de nitrogênio na folha e no pecíolo em videiras submetidas à adubação nitrogenada Grapes yield, composition and nitrogen content in leaf and leaf petioles in grapevine with nitrogen fertilization

Ciência Rural, 2008
A videira tem grande importância econômica no Sul do Brasil, mas sua produtividade está associada à utilização de fertilizantes, especialmente nitrogenados, que afetam a produtividade e a composição das bagas.

Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis

New Phytologist, Volume 248, Issue 1, Page 76-91, October 2025.
Summary Recent studies have shown a linear relationship between solar‐induced Chl fluorescence (SIF) and gross primary productivity (GPP) at large scales. However, this relationship diverges at finer leaf scales, particularly in tropical forests with complex canopy structures.

Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

Journal of Ecology, Volume 113, Issue 9, Page 2414-2428, September 2025.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.

Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities

Global Change Biology, Volume 31, Issue 3, March 2025.
Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.
