Solo, topografia, mortalidade e recrutamento de árvores na floresta tropical decidual

Gaia Scientia, 2018
Muitos são os fatores que podem aumentar ou diminuir a intensidade da dinâmica nas florestas tropicais. Com certeza o clima pode ser considerado fator determinante para as taxas de mortalidade e recrutamento de arvores nestas florestas. Entretanto, a topografia e o tipo de solo também são fatores que sinergicamente influenciam a distribuição e ...

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, Volume 168, Issue 2, Page 571-587, April 2026.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.
