On the botanical history and nomenclature of the New World genus Piscidia (Fabaceae)

Nordic Journal of Botany, EarlyView.
Piscidia L. (Fabaceae) is a New World genus with nine recognized taxa (seven species and two varieties). The previous nomenclatural revisions, made in 1910 and in 1969, are revisited here. The names Derris grandifolia Heyde & Lux ex Donn.Sm. and P. cubensis Urb. required step II lectotypifications, with an epitype for the latter name.

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

Remote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.
