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 ...

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects
Animal Conservation, Volume 27, Issue 5, Page 722-735, October 2024.Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...

Ecological Monographs, Volume 94, Issue 3, August 2024.Abstract Peatlands store large amounts of carbon (C), a function potentially threatened by climate change. Peatlands composed of vascular cushion plants are widespread in the northern and central high Andes (páramo, wet and dry puna), but their C dynamics are hardly known.

Net primary productivity and litter decomposition rates in two distinct Amazonian peatlands
Global Change Biology, Volume 30, Issue 8, August 2024.Our understanding of carbon cycling in tropical peatlands is limited by the lack of data on forest productivity and litter decomposition. Here we present measurements from two floristically distinct Amazonian peatland forests, a palm‐dominated swamp and a thin‐stemmed hardwood swamp.

Multiple‐stressor effects on leaf litter decomposition in freshwater ecosystems: A meta‐analysis
Functional Ecology, Volume 38, Issue 7, Page 1523-1536, July 2024.Read the free Plain Language Summary for this article on the Journal blog. Abstract Recent years have witnessed a surge in research on the effects of multiple stressors in freshwater ecosystems. While studies have increased, the synthesis of their findings into a broader understanding of ecosystem‐level effects remains an ongoing endeavour. Leaf litter
