Published in 2024 at "Ecology and Evolution"

DOI: 10.1002/ece3.10865

Abstract: Abstract Social behaviour is thought to be a major component of survival, reproduction, and resilience of populations. Thus, it is a key component in management and conservation of wild populations. In polygynous breeding species, group… read more here.

Published in 2025 at "Ecography"

DOI: 10.1002/ecog.07740

Abstract: Global change is altering forests worldwide, with multiple consequences for ecosystem functioning. Temporal changes in climate, and extreme, compounded weather events like hotter droughts are affecting the demography, composition and function of forests, leading to… read more here.

Published in 2017 at "Human Brain Mapping"

DOI: 10.1002/hbm.23453

Abstract: Two powerful methods for statistical inference on MRI brain images have been proposed recently, a non‐stationary voxelation‐corrected cluster‐size test (CST) based on random field theory and threshold‐free cluster enhancement (TFCE) based on calculating the level… read more here.

Published in 2017 at "International Journal of Climatology"

DOI: 10.1002/joc.5188

Abstract: The biases in the Global Circulation Models (GCMs) are crucial for understanding future climate changes. Currently, most bias correction methodologies suffer from the assumption that model bias is stationary. This paper provides a non-stationary bias… read more here.

Published in 2019 at "International Journal of Climatology"

DOI: 10.1002/joc.6065

Abstract: The extreme precipitation regimes have been changing as the climate system has warmed. Investigating the non‐stationarity and better estimating the changes of the extreme precipitation are valuable for informing policy decisions. In this study, two… read more here.

Published in 2021 at "International Journal for Numerical Methods in Engineering"

DOI: 10.1002/nme.6812

Abstract: Polarization‐type methods are among the fastest solution methods for FFT‐based computational micromechanics. However, their performance depends critically on the choice of the reference material. Only for finitely contrasted materials, optimum‐selection strategies are known. This work… read more here.
