Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient. [PDF]

New Phytol
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Microclimatic variation regulates seed germination phenology in alpine plant communities

Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.
This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.

La sombra alargada del patrón: Gamonalismo y hábitos hacendatarios en Chimborazo tras la reforma agraria

The Journal of Latin American and Caribbean Anthropology, Volume 29, Issue 4, Page 352-363, December 2024.
Abstract This paper explores selective aspects of the historical processes of organization of the kichwa peasantry in the Andes of Ecuador. Based on the analysis of two representative cases of confrontation between peasants and landowners over access to land in the province of Chimborazo, it discusses the relevance of the concept of “gamonalismo” as ...
