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 ...

Avian phylogenetic and functional diversity are better conserved by land‐sparing than land‐sharing farming in lowland tropical forests

Journal of Applied Ecology, Volume 61, Issue 10, Page 2497-2509, October 2024.
To minimise the loss of avian phylogenetic diversity and functional traits from farming in the Amazon, it is imperative to protect large blocks of undisturbed and regenerating forests. The intensification required within existing farmlands to make space for spared lands while meeting agricultural demand needs to be sustainable, avoiding long‐term ...

Balancing quality with quantity: A case study of UK bread wheat

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1000-1013, September 2024.
Increasing crop productivity is often proposed as a key goal for meeting the food security demands of a growing global population. However, achieving high crop yields alone without meeting end‐use quality requirements is counter to this objective and can lead to negative environmental and sustainability issues.

Global mismatches between threat mapping research effort and the potential of threat abatement actions to reduce extinction risk

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Threat mapping is a necessary tool for identifying and abating direct threats to species in the ongoing extinction crisis. There are known gaps in the threat mapping literature for particular threats and geographic locations, and it remains unclear if the distribution of research effort is appropriately targeted relative to conservation need ...

Effects of human depopulation and warming climate on bird populations in Japan

Conservation Biology, Volume 38, Issue 2, April 2024.
Abstract Quantifying biodiversity trends in economically developed countries, where depopulation, associated secondary succession, and climate warming are ongoing, provides insights for global biodiversity conservation in the 21st century. However, few studies have assessed the impacts of secondary succession and climate warming on species’ population ...

Extinction risk of the world's freshwater mammals

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract The continued loss of freshwater habitats poses a significant threat to global biodiversity. We reviewed the extinction risk of 166 freshwater aquatic and semiaquatic mammals—a group rarely documented as a collective. We used the International Union for the Conservation of Nature Red List of Threatened Species categories as of December 2021 to

Meta‐analysis contrasting freshwater biodiversity in forests and oil palm plantations with and without riparian buffers

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract The expansion of oil palm plantations has led to land‐use change and deforestation in the tropics, which has affected biodiversity. Although the impacts of the crop on terrestrial biodiversity have been extensively reviewed, its effects on freshwater biodiversity remain relatively unexplored.
