Does invasion by armored catfish shift trophic ecology of native fishes? Evidence from stable isotope analysis

open access: yesEcology, Volume 104, Issue 5, May 2023., 2023
Abstract Popular as aquarium fish, armored catfishes from South America (Pterygoplichthys spp.) have been introduced and become invasive in tropical and subtropical regions worldwide. These ecosystem engineers can deplete basal resources (e.g., periphyton and detritus), with potential negative effects for native fauna. We studied the trophic ecology of

Urban–rural continuum: an overview of their interactions and territorial disparities

open access: yesRegional Science Policy &Practice, Volume 15, Issue 4, Page 729-768, May 2023., 2023
Abstract This study provides a quantitative analisis of the interactions between urban and rural areas and related territorial disparities in the European Union (EU). Relevant societal themes such as population changes, access to services, broadband internet connectivity, house prices, tourism and land‐use/cover flows are examined by mean of indicators

Skill‐Relatedness and Regional Economic Development in Spain during the International Crisis and the Post‐Crisis Period

open access: yesPapers in Regional Science, Volume 101, Issue 3, Page 573-602, June 2022., 2022
Abstract The aim of this research was to study the influence of related variety on the economic performance of Spanish provinces during the international crisis (2009–2013) and the post‐crisis period (2014–2018), with the goal of contributing to assess the validity of the skill‐relatedness approach.

Translocation effects on regional and local population viability and connectivity

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Translocations and reintroductions aim to improve the viability of isolated populations and promote connectivity for large carnivores. However, there is no established framework for assessing their success. We used the Eurasian lynx (Lynx lynx) in western and central Europe to assess the impact of translocations on the viability of six ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

open access: yesThe Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Policy Windows in an Authoritarian System: How Alignment, Leadership Signals, and Disasters Enabled Policy Entrepreneurship in China's Poverty Alleviation

open access: yesReview of Policy Research, Volume 43, Issue 4, July 2026.
ABSTRACT China's poverty alleviation campaign is significant. Over the past four decades, the number of people in China living below the international extreme‐poverty line fell by close to 800 million, accounting for nearly three‐quarters of the global reduction in extreme poverty.

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Simulating drying and human impacts on river networks to evaluate biological quality indices performance through the lens of metacommunity theory

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
This work constitutes a first step towards developing simulation‐based assessments that incorporate catchment drying patterns to support biomonitoring of drying river networks. Our approach can inform stakeholders when current methods are likely to fail and contribute to decision‐making on whether adapting current methods is possible or developing new ...

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

open access: yesMolecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.
