Managed forests are a stronghold of non‐native beetles in Europe

Journal of Applied Ecology, Volume 62, Issue 5, Page 1243-1257, May 2025.
Species richness of native and non‐native vascular plants modulates the species richness of non‐native beetles through relationships with opposite signs. The interplay with management regimes and forest structures determines whether non‐native beetles are promoted.

Joint analysis of longitudinal count and binary response data in the presence of outliers

Canadian Journal of Statistics, Volume 53, Issue 1, March 2025.
Abstract In this article, we develop an innovative, robust method for jointly analyzing longitudinal count and binary responses. The method is useful for bounding the influence of potential outliers in the data when estimating the model parameters. We use a log‐linear model for the count response and a logistic regression model for the binary response,

Spatially explicit predictions using spatial eigenvector maps

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 2129-2140, November 2024.
Abstract In this paper, we explain how to obtain sets of descriptors of the spatial variation, which we call “predictive Moran's eigenvector maps” (pMEM), that can be used to make spatially explicit predictions for any environmental variables, biotic or abiotic. It unites features of a method called “Moran's eigenvector maps” (MEM) and those of spatial

The soft channels of policy diffusion: Insights from local climate change adaptation policy

Policy Studies Journal, Volume 52, Issue 4, Page 881-906, November 2024.
Abstract Diffusion has become both an important concept for studying policy spread and a popular governance approach, particularly where direct coercion is unavailable or undesirable. However, the prevailing mechanism‐centered concept is difficult to measure and poorly captures the governance potential of policy diffusion. To address these issues, this

Fused mean structure learning in data integration with dependence

Canadian Journal of Statistics, Volume 52, Issue 3, Page 939-961, September 2024.
Abstract Motivated by image‐on‐scalar regression with data aggregated across multiple sites, we consider a setting in which multiple independent studies each collect multiple dependent vector outcomes, with potential mean model parameter homogeneity between studies and outcome vectors. To determine the validity of a joint analysis of these data sources,
