Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...

The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers of tropical tree death remain largely unknown. Here we present a pan-Amazonian assessment of how and why trees die, analysing over 120,000 trees representing > 3800 species from 189 long-term RAINFOR forest plots. While tree mortality...

Aim: Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) an...

Higher levels of taxonomic and evolutionary diversity are expected to maximize ecosystem function, yet their relative importance in driving variation in ecosystem function at large scales in diverse forests is unknown. Using 90 inventory plots across intact, lowland, terra firme, Amazonian forests and a new phylogeny including 526 angiosperm genera...

The genus Dicaryum Willd. ex Roem. & Schult. was described in 1819 and does not have a type species. Two species were described, and one, D. subdentatum Willd. ex Roem. & Schult., is better selected as the type because the other species, D. serrulatum Willd. ex Roem. & Schult., is not a Verbenaceae but rather a Primulaceae-Myrsinoideae and belongs...

Rapanea pellucidostriata Gilg & Schellenb. is transferred to Myrsine L. as M. pellucidostriata (Gilg & Schellenb.) Pipoly & Ricketson, comb. nov. To our knowledge, this is the last species of Rapanea Aubl. remaining that did not have a name in the genus Myrsine. With the transfer of this species complete, all species of Rapanea and Suttonia A. Rich...

Cybianthus condorensis Pipoly & Ricketson, a new species from the Cordillera del Condor of Ecuador and Peru, is described herewith. Because of its alternate, coriaceous, and revolute leaves; scattered to densely appressed lepidote branchlets, inflorescence rachises, and calyces; subsessile pistillate flowers; and sandy habitat, this species is easi...

Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance of these processes requires large-scale quantification of traits and evolutionary relationships among species....

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of...
