Intra‐Urban Migration and Residential Concentration Patterns of Foreign‐Born Migrants. The Case of Barcelona (2012–2021)

Population, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT The territorial concentration of the foreign‐born population in large cities is determined by the evolution of international migration flows, as well as by the internal demographic and migration dynamics of both native‐born and immigrant populations.

Dialectical Geopolitics in the Multipolar Energy Era

World Affairs, Volume 189, Issue 3, Fall 2026.
ABSTRACT This paper develops a dialectical geopolitics–geoeconomics framework for interpreting the restructuring of globalization and the emergence of a multipolar energy era. It operationalizes nine dialectical prerequisites as a diagnostic “protocol” for international relations/international political economy (IR/IPE): specify endogenous ...

Landscape forest cover, not edge contrast, modulates edge effects on palm diversity

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our findings demonstrate that landscape forest cover plays a critical role in modulating edge effects in plant communities in our study system, but not all woody crops systems provide buffering benefits, as cacao plantations in our study failed to soften edge effects.

An integrated approach to balance freshwater connectivity restoration and invasion risk

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions

Conservation 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

Urban–Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
