Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies

open access: yesPolicy Studies Journal, Volume 54, Issue 1, February 2026.
ABSTRACT Research on advocacy coalitions suggests that belief homophily—the tendency of actors to coordinate based on shared policy beliefs—drives coalition formation. However, coalition opportunity structures, which are shaped by institutional contexts, may influence the extent to which belief homophily matters.

Enhancing multitasking capacity: An acoustic tagging and sampling methodology for the spiny butterfly ray (Gymnura altavela) in the Canary Islands

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
To overcome challenges in studying elusive benthic elasmobranchs, a comprehensive, rapid methodology was developed and applied to 133 Spiny Butterfly Rays in Gran Canaria and Tenerife between 2020 and 2024. This approach integrated internal tagging with acoustic and external T‐bar tags, alongside biological sampling and ultrasound assessments, all ...

Which global circulation model works best for my region? Concordance with genetic data for a Neotropical shrew

open access: yesEcography, Volume 2025, Issue 12, December 2025.
Copious questions in global change biology require estimates of climatic suitability for species in the past or future, often via transfers of ecological niche models (ENMs) using outputs from global circulation models (GCMs). However, available GCMs differ markedly, affecting hindcasts and forecasts of species potential distributions. We propose using
