Data and code from: Macroevolutionary dynamics and predictors of tropical rain forest plant diversity

Laura Holzmeyer, Francis J. Nge, Susanna Arias Guerrero, Kate E. Armstrong et autres

Tropical rain forest (TRF) is the most diverse terrestrial biome, yet the drivers of its diversification across space and time remain poorly understood. Although heterogeneous diversification rates, including both ancient and recent radiations, have been reported, these dynamics have rarely been examined …

Rediscovery of Ravenea latisecta Jum. (Arecaceae) after a century, and the conservation implications

Louis Aureglia, Laurent Hardion, Mijoro Rakotoarinivo, Bruno Vila

Abstract Rediscoveries of endemic plant species previously believed lost recalibrate conservation priorities by revealing relict populations and underscore the need for botanical surveys. Since its description in 1927, Ravenea latisecta , a palm species endemic to Madagascar, had been considered lost for …

PLANeT: Understanding and leveraging the genome of land plants for a sustainable future

Li Wang, Mohamed Amar, Carlos I. Arbizu, John L. Bowman et autres

Land plants underpin civilization and planetary health, yet their genomic diversity remains largely uncharted. Current resources are unstandardized and scarce, lacking reference genomes for 95% of genera, 70% of families, and 51% of orders, impeding evolutionary and functional insight. We thus propose …

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

Rindra Manasoa Ranaivoson, Romer Narindra Rabarijaona, Jinren Yu, Yi‐Chen You et autres

Genome size, the total amount of DNA content in the cell nucleus, varies greatly among flowering plants. One factor underlying this variation is the environment under which plants evolve. Given this premise, harsh environmental conditions in arid regions may profoundly influence genome …
