A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

A Comparison Between Markov Switching Zero‐Inflated and Hurdle Models for Spatio‐Temporal Infectious Disease Counts

open access: yesStatistics in Medicine, Volume 44, Issue 13-14, June 2025.
ABSTRACT In epidemiological studies, zero‐inflated and hurdle models are commonly used to handle excess zeros in reported infectious disease cases. However, they cannot model the persistence (transition from presence to presence) and reemergence (transition from absence to presence) of a disease separately.
