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

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

Journal 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

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

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

Insect 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
