New Phytologist, EarlyView.Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

New Phytologist, EarlyView.Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Narrative power in the narrative policy framework
Policy Studies Journal, EarlyView.Abstract The Narrative Policy Framework lacks clear and empirical explanations of power. Yet, the study of narratives is inherently the study of power in shaping policy outputs and decisions. We develop a conceptual model positing that expressions of power (power to, with, and over) may be discovered in narrative constructs (e.g., narrative structure ...

Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies
Policy Studies Journal, EarlyView.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.

Non‐Members in a Tight Spot: How Norway Navigated Autonomy in EU Pandemic Management
Review of Policy Research, EarlyView.ABSTRACT This study offers new insights into how closely integrated non‐member states navigate tensions between autonomy and dependence when urgent policy responses are required within complex supranational frameworks. It does so by exploring how these non‐members exercise their “wriggle room”—a tailored sub‐category of the broader concept of autonomy ...

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant
New Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of
