CMiNet: An R package and user‐friendly Shiny App for constructing consensus microbiome networks

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 52-66, January 2026.
Abstract Microbial networks offer critical insights into community structure, ecological interactions and host–microbe dynamics. However, constructing reliable microbiome networks remains challenging due to variability among existing inference methods, limited overlap between inferred networks and the absence of a gold standard (a universally accepted ...

Mammals with large home ranges, low reproductive rates and small body sizes are most vulnerable to roads: A meta‐analysis

Journal of Applied Ecology, Volume 62, Issue 12, Page 3227-3239, December 2025.
Road mitigation for mammals should ideally be informed by site‐level knowledge and generally involve prioritizing species with the combination of larger home ranges, lower reproductive rates and smaller body sizes. To protect these vulnerable mammals from roads, we should maintain low road densities and instal small‐mesh mitigation fencing along roads.

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

Using Environmental DNA Sampling for Simultaneous Detection of Hosts and Their Pathogens: A Case Study With the Critically Endangered Frog Genus Atelopus

Animal Conservation, Volume 28, Issue 5, Page 663-674, October 2025.
Environmental DNA is a powerful tool for simultaneous detection of rare species and their pathogens. We confirmed the presence of Atelopus at multiple sampling locations and found that the concentration of the amphibian pathogen Bd in eDNA samples was correlated with stream characteristics and the pathogen load of the amphibian community.
