Genetic inference of orchid colonization of a Costa Rican lava flow

open access: yesBiotropica, 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

open access: yesConservation 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

Standardised empirical dispersal kernels emphasise the pervasiveness of long‐distance dispersal in European birds

open access: yesJournal of Animal Ecology, Volume 92, Issue 1, Page 158-170, January 2023., 2023
Introducing a statistical framework to estimate standardised dispersal kernels from biased data. The authors found strong evidence that long‐distance dispersal is common among European breeding bird species and across life stages. Their dispersal estimates for 234 bird species can guide selecting appropriate dispersal kernels in range expansion studies

AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest

open access: yesEcology, Volume 103, Issue 9, September 2022., 2022
Abstract The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time

Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores

open access: yesEcological Solutions and Evidence, Volume 3, Issue 2, April–June 2022., 2022
Pollination of native cacao is surprisingly understudied, even though the process is crucial for the global chocolate production. In an understudied peruvian region, we found herbivores as dominant flower visitors, and low pollen deposition.Fruit set was low when flowers were pollinated naturally (2%), but also manually (7%). Our findings highlight the

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

open access: yesInsect Science, Volume 32, Issue 6, Page 2105-2124, December 2025.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of
