Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

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.

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Archeological and mtDNA evidence for Tropical Lowland migrations during the Late Archaic / Formative in northern Chile Evidencia arqueológica y de ADNmt para migraciones de Tierras Bajas Tropicales Durante el Arcaico Tardío/Formativo Temprano en el norte de Chile

Revista Chilena de Historia Natural, 2009
The influence of tropical lowland migrations on the emergence of cultural change in the Central Andes has been postulated in general terms since the beginning of last century (Tello 1929).

Repeated trends in altitudinal gradients of diversity: How habitat filtering and biotic interactions structure ecological communities

Journal of Animal Ecology, EarlyView.
This study reveals that tropical butterfly communities show remarkably consistent elevational patterns of diversity and phylogenetic structure across regions with contrasting evolutionary histories, demonstrating how regional species pools and local ecological factors jointly shape biodiversity along altitudinal gradients.
