Captured participatory institutions: Theory and evidence from Venezuela's Consejos Comunales

American Journal of Political Science, EarlyView.
Abstract Can participatory institutions (PIs) facilitate development when captured by the government? We propose an original theoretical framework to investigate how changing incumbent priorities can shape the developmental and political effects of captured PIs.

Phenological Flexibility in Nesting Grassland Birds Over a Half Century Informs Timing of Management

Global Change Biology, Volume 32, Issue 10, October 2026.
Using > 170,000 nest records from 44 North American grassland bird species, we quantified how temperature, precipitation, and vegetation phenology shape early, peak, and late nesting across broad spatial gradients. Spatial predictions identify geographic variation in breeding phenology that can inform the timing of management actions under changing ...

Systematics and Historical Biogeography of Neotropical Tarantulas: A Genomic Approach to Dolichothele (Araneae: Theraphosidae) Diversification Across Domains

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim The Neotropical region is the most biodiverse in the world, and several hypotheses have been proposed to explain this pattern. Among them, the most prominent are the hypotheses of biotic interchange between domains, climatic refugia during the Pleistocene and geomorphological changes during the Miocene, such as the reorganization of the ...

Efficacy and safety of a topical nitric oxide–releasing solution (NORS) as a noninvasive treatment for plantar warts (verrucae plantaris)

Journal of Dermatological Treatment
Background Plantar warts (verrucae plantaris), caused by human papillomavirus, are common and often resistant to standard therapies, which can be painful and damaging. Novel, noninvasive options are needed.Objective To evaluate the safety and preliminary

Student–teacher relationships as a mediator of children's education‐linked genetics: results from the Norwegian Mother, Father and Child Cohort Study

Journal of Child Psychology and Psychiatry, Volume 67, Issue 10, Page 1729-1740, October 2026.
Background Genetic differences are robustly associated with educational outcomes, but how they become linked is poorly understood. A plausible hypothesis, yet to be thoroughly empirically tested, is that the school environment mediates the association. Methods Using structural equation models, we tested whether the student–teacher relationship at age 5
