Genetic inference of orchid colonization of a Costa Rican lava flow
Biotropica, Volume 55, Issue 6, Page 1195-1202, November 2023., 2023 A 1992 lava flow provides an excellent opportunity to study patterns of colonization and growth of plant populations on a naturally disturbed site. Plants with wind‐dispersed seeds, such as orchids, are often among the earliest colonists after habitat disturbance.

Validating graph‐based connectivity models with independent presence–absence and genetic data sets
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Habitat connectivity is a key objective of current conservation policies and is commonly modeled by landscape graphs (i.e., sets of habitat patches [nodes] connected by potential dispersal paths [links]). These graphs are often built based on expert opinion or species distribution models (SDMs) and therefore lack empirical validation from data

Automated identification of diverse Neotropical pollen samples using convolutional neural networks
Methods in Ecology and Evolution, Volume 13, Issue 9, Page 2049-2064, September 2022., 2022 Abstract Pollen is used to investigate a diverse range of ecological problems, from identifying plant–pollinator relationships to tracking flowering phenology. Pollen types are identified according to a set of distinctive morphological characters which are understood to capture taxonomic differences and phylogenetic relationships among taxa.
