Riverscape heterogeneity shapes population diversity for a migratory fish

open access: yesEcological Applications, Volume 36, Issue 4, June 2026.
Abstract Habitat patch dynamics can scale up to influence population demography and diversity with implications for resilience to environmental stochasticity. But how the spatial arrangement and size of habitat patches interact with other components of habitat heterogeneity to shape population diversity at larger spatial scales is not well understood ...

Pareto Chart: A Tool to Evaluate Development of Regional Disparities

open access: yes, 2016
This paper seeks to demonstrate how the Pareto chart can be used as a tool to evaluate development of regional disparities. The introduction of the chart is followed by its application to the regions of Visegrad Group states. The σ-convergence approach has been used as a benchmark to examine the estimates arrived at using Pareto chart.
