Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

Journal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Species functional traits affect regional and local dominance across western Amazonian forests

Journal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

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 ...

Endogenous rhythmic growth and ectomycorrhizal fungi modulate priming of antiherbivore defences in subsequently formed new leaves of oak trees

Journal of Ecology, Volume 113, Issue 6, Page 1382-1396, June 2025.
A first herbivore attack primes direct and indirect defences of newly formed oak leaves and, the specific display of defence priming is regulated by rhythmic growth, and modulated by the interaction with the ectomycorrhizal fungus Piloderma croceum. Therefore, the priming memory in oaks can be transmitted to the next growth cycle. GC, growth cycle; SF,

Índice de Área Foliar em Caatinga Preservada

Conexões: Ciência e Tecnologia, 2016
O índice de área foliar (IAF) é um parâmetro biofísico que tem influência sobre vários processos ambientais, tais como fotossíntese, transpiração e balanço de radiação da superfície, sendo um importante parâmetro de entrada de modelos ecológicos.
