Long‐Term Fire and Vegetation Change at Cocha Cashu Biological Station, Peru

Biotropica, Volume 57, Issue 3, May 2025.
Cocha Cashu is a dynamic system that has experienced various forms of past ecological turnover. However, the dynamism seen at Cocha Cashu was not caused by intensive human activities in the past. ABSTRACT Past human influence from the pre‐Columbian and colonial periods may have played a role in shaping modern Amazonian vegetation.

Analyzing the relative importance of habitat quantity and quality for boosting pollinator populations in agricultural landscapes

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract To increase pollinator populations, international policy targets minimum levels of seminatural habitat cover, but it is unknown whether improving the quality of existing habitats could bring similar benefits without the need of reducing cropland area. Using data we collected in 26 Italian agricultural landscapes during the entire flying season,

Linking landscape structure, floral resource distribution, pollen use and movement distances of a generalist predator

Journal of Applied Ecology, Volume 61, Issue 11, Page 2798-2808, November 2024.
Our findings suggest that the spatial distribution of flowering wild plants can inform movement patterns of lacewings and other flower‐visiting insects in agricultural landscapes. In addition, the location of floral resources in the landscape is important for its capacity to sustain natural enemies. Given the strong reliance of lacewings on pollen from

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 ...

Early Colonial Diet in El Japón, Xochimilco, Mexico: Examining dietary continuity through stable isotope analysis of bone collagen and bioapatite

American Journal of Biological Anthropology, Volume 184, Issue 3, July 2024.
Location of the Colonial period site of El Japón (San Gregorio Atlapulco, Mexico City). Abstract Objectives Early colonial documents from central Mesoamerica detail raising and planting of European livestock and crops alongside native ones. The extent to which Indigenous people, especially of the rural commoner class, consumed newly introduced foods is
