Espíritus animales y narrativas populares virales

El Trimestre Económico, 2021
El concepto de John Maynard Keynes (1936) de “espíritus animales” o de “optimismo espontáneo” como una de las principales fuerzas que impulsan las fluctuaciones económicas se inspiró en parte por sus reflexiones y las de sus contemporáneos sobre las ...

Spatially asymmetric and temporally dynamic ecological responses to river barrier removal: A global meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
Barrier removal initiates ecological recovery rather than delivering immediate restoration, with responses shaped by spatial context, initial conditions and time since removal. Monitoring should therefore extend beyond the first post‐removal year and, where feasible, continue for at least 5 years, particularly in downstream reaches, while incorporating

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Predictive evolutionary genomics: principles, validation, and practice

New Phytologist, Volume 252, Issue 1, Page 36-48, October 2026.
Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Growing up otherwise: Situated ethics and pathways to non‐violence in Southern Brazil

Ethos, Volume 54, Issue 3, September 2026.
Abstract This paper proposes a reframing of how young men become embroiled—or not—in the systemic violence that infuses their daily lives. Most frameworks in health and social policy tend to approach violence as rooted in psycho‐developmental problems and/or social and structural determinants.
