Integrating terrestrial and canopy laser scanning for comprehensive analysis of large old trees: Implications for single tree and biodiversity research

Remote Sensing in Ecology and Conservation, EarlyView.
Canopy laser scanning (CLS) enhances 3D measurements of large trees by lifting laser scanners into the canopy. Combining CLS with terrestrial laser scanning improves point cloud precision, reduces occlusion and enables detailed assessments of tree architecture and canopy biodiversity, opening new opportunities for forest ecology.

Another puzzle piece: new record of the Fringed Leaf Frog, Cruziohyla craspedopus (Funkhouser, 1957) (Anura: Phyllomedusidae), in the eastern Amazon Rainforest [PDF]

Check List, 2017
We report new occurrence of Cruziohyla craspedopus (Funkhouser, 1957) in the eastern Amazon Rainforest. This is only the second record from the state of Pará, Brazil and represents the easternmost known point of this species’ range.

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.

Surprising chiral composition changes over the Amazon rainforest with height, time and season

Communications Earth & Environment, 2020
The chiral compositions of biogenic volatile organic compounds over the Amazon tropical rainforest vary with height, time of day and season, according to measurements from a 325 m tall tower.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

TAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species
