Widespread introduced species dominate the urban tree assemblage on the endemic‐rich tropical island of São Tomé

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Afrotropical cities are growing rapidly but how this impacts biodiversity is largely unclear. Our study on São Tomé Island, Central Africa, reveals that the urban tree assemblage is impoverished and dominated by introduced species, while the natural forest is essential for the protection of native and endemic species.

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

open access: yesJournal of Biogeography, Volume 51, Issue 7, Page 1163-1184, July 2024.
Abstract Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly ...
