Vertebrate diversity and biomass along a recovery gradient in a lowland tropical forest

Biotropica, Volume 57, Issue 1, January 2025.
Deforestation of tropical forests has resulted in large areas of secondary forests with the potential for biodiversity to re‐establish to levels usually found in old‐growth forests. This study shows that diversity and biomass of mammals and birds in regenerating forests can recover to old‐growth levels within a relatively short time.

Aggregated Demand Flexibility Prediction of Residential Thermostatically Controlled Loads and Participation in Electricity Balance Markets

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The aggregate demand flexibility of a set of residential thermostatically controlled loads (TCLs) can be represented by a virtual battery (VB) in order to manage their participation in the electricity markets. For this purpose, it is necessary to know in advance and with a high level of reliability the maximum power that can be supplied by the ...

Tree species abundance changes at the edges of their climatic distribution: An interplay between climate change, plant traits and forest management

Journal of Ecology, Volume 112, Issue 12, Page 2785-2797, December 2024.
Our research emphasizes the crucial impact of historical forest management in shaping the current distribution of tree species. After controlling for the effect of forest management, climate change directly influenced tree demographics, favouring species based on their traits.

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 ...

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

Caracterización de la madera de Castanea sativa Mill. de procedencia española [PDF]

, 2011
La madera de castaño de procedencia española no está presente como material estructural en la norma europea EN 1912, y por lo tanto no está asignada a ninguna clase resistente como sí lo están otras especies españolas. Por ello, en el presente trabajo se

A methodological workflow for quantitative colouration and colour pattern comparison reveals taxonomic and habitat‐level differences in the polymorphic fire salamander (Salamandra salamandra)

Journal of Zoology, Volume 324, Issue 1, Page 34-49, September 2024.
In this study, we use the urodele Salamandra salamandra as a study model to apply an analytical approach for extracting and quantifying colour proportions and patterns variation, using the recently developed R packages patternize and recolorize, to accurately describe and compare colour distribution at both taxonomic and habitat levels.
