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

Automated identification of diverse Neotropical pollen samples using convolutional neural networks

open access: yesMethods 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.

Cascading effects of climate variability on the breeding success of an edge population of an apex predator

open access: yesJournal of Animal Ecology, Volume 89, Issue 11, Page 2631-2643, November 2020., 2020
The authors demostrate how climate interacts with local demography to determine population fitness and viability. The mechanistic approach taken allowed us to unravel the cascading effects of the annual fluctuations of a major climatic phenomenon over the Atlantic on the vital rates of a wild bird population, and provided the first evidence of wind as ...

Hyperspectral outcrop models for palaeoseismic studies

open access: yesThe Photogrammetric Record, Volume 34, Issue 168, Page 385-407, December 2019., 2019
To overcome the limitations of the traditional study of palaeoseismic trenches, a new workflow is presented that integrates infrared hyperspectral and photogrammetric data. This method was applied on two palaeoseismic trenches excavated across a post‐glacial fault scarp in northern Finnish Lapland.

Branch Optimal Power Flow Model for DC Networks with Radial Structure: A Conic Relaxation

open access: yesTecnura, 2022
Abstract Objective: This work involves a convex-based mathematical reformulation for the optimal power flow problem in DC networks. The objective of the proposed optimization model corresponds to the minimization of the power losses through all the network branches considering a convex conic model that warranties finding the global optimal ...

adm: An R package for constructing abundance‐based species distribution models

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 7, Page 1404-1412, July 2025.
Abstract Abundance‐based species distribution models (ADM) correlate species abundance with environmental data to model and project abundance throughout space or time. This promising and still developing technique has gained significant attention in recent years. Here, we present the adm R package developed to support the construction of ADM, including
