Drivers and potential solutions for transnational Illegal, Unreported and Unregulated fishing (IUU) in the Gulf of Honduras

open access: yesPeople and Nature, Volume 7, Issue 6, Page 1321-1333, June 2025.
Abstract The threat of Illegal, Unreported and Unregulated (IUU) fishing to global fisheries, particularly in lower‐income tropical regions, underscores the urgent need for science‐based solutions. This study explores the drivers and potential solutions to IUU fishing by Honduran fishers in the Cayman Crown reef, located within the territorial waters ...

Heterogeneidade espacial e diversidade de abelhas Meliponini na Mata Atlântica (RPPN da Michelin, Bahia)

open access: yesSITIENTIBUS série Ciências Biológicas, 2008
Freqüentemente, as abelhas sem ferrão ou meliponíneos (Apidae, Hymenoptera) constituem o grupo mais numeroso de visitantes florais nas florestas tropicais, como a Mata Atlântica (MA). Na MA, a fauna de meliponíneos apresenta variações na diversidade em escala espacial local, provavelmente, associadas às diferenças espaciais na estrutura da vegetação ou

Strong scale‐dependent relationships between fine‐root function and soil properties uncovered with spatially coupled sampling

open access: yesNew Phytologist, Volume 246, Issue 6, Page 2506-2521, June 2025.
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Game target‐group: Implementing inhomogeneous Poisson point process to estimate animal abundance from harvest data

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 1, Page 170-182, January 2025.
Abstract Harvest data have the potential to be used as an abundance index due to its widespread availability and long‐term collection across large geographical areas. However, challenges such as the lack of hunting effort information, varying data resolutions and reporting biases hinder its direct use as an abundance proxy.

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 ...

Modeling the risk of aquatic species invasion spread through boater movements and river connections

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Aquatic invasive species (AIS) are one of the greatest threats to the functioning of aquatic ecosystems worldwide. Once an invasive species has been introduced to a new region, many governments develop management strategies to reduce further spread.

Importance of habitat heterogeneity in tidal flats to the conservation of migratory shorebirds

open access: yesConservation Biology, Volume 38, Issue 1, February 2024.
Abstract Understanding species distribution patterns and what determines them is critical for effective conservation planning and management. In the case of shorebirds migrating along the East Asian‐Australasian Flyway (EAAF), the loss of stopover habitat in the Yellow Sea region is thought to be the primary reason for the precipitous population ...

Técnicas para la predicción espacial de zonas susceptibles a deslizamientos

open access: yesAvances, 2019
Si bien las técnicas implementadas para predecir zonas susceptibles a procesos de remoción en masa han logrado modelar con cierto grado de precisión casos de deslizamientos, no logran modelar eventos complejos, donde la relación entre los deslizamientos ...
