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

open access: yesThe 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 ...

The Coloniality of Space: Landscape, Aesthetics, and the Middle Classes in Dar es Salaam

open access: yesAntipode, Volume 56, Issue 6, Page 2202-2223, November 2024.
Abstract In Dar es Salaam, an aesthetic politics of landscape shaped by the coloniality of space is central to middle‐class boundary work that drives the city's middle classes to congregate in the city's northern suburbs. The colonial city was divided into three racially marked zones that became known as uzunguni, uhindini, and uswahilini (the place of

Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Carbon dynamics in high‐Andean tropical cushion peatlands: A review of geographic patterns and potential drivers

open access: yesEcological 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.

Ensemble modelling to predict the distribution of vulnerable marine ecosystems indicator taxa on data‐limited seamounts of Cabo Verde (NW Africa)

open access: yesDiversity and Distributions, Volume 30, Issue 8, August 2024.
Abstract Aim Seamounts are conspicuous geological features with an important ecological role and can be considered vulnerable marine ecosystems (VMEs). Since many deep‐sea regions remain largely unexplored, investigating the occurrence of VME taxa on seamounts is challenging.

Dynamics of tree stems and biomass in old‐growth and secondary forests along gradients in liana dominance, elevation and soil

open access: yesJournal of Ecology, Volume 112, Issue 7, Page 1638-1654, July 2024.
Secondary tropical forests can show resilience, maintaining carbon storage and ecological functions despite disturbances. Tree dynamics are influenced by elevation, soil properties and complex interactions with lianas, which can have both positive and negative impacts, depending on the context. These insights can guide ecosystem restoration strategies,
