Through the Prism of eDNA: Exploring Cryptic Freshwater Bivalves Diversity in a Mega‐Diverse Tropical Environment

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Extensive eDNA sampling in remote tropical rivers revealed six new species, two of which were later confirmed through traditional surveys and formally described. eDNA also captured basin‐scale haplotype diversity, showing that pristine upstream areas harbor both more species and higher genetic diversity than sites affected by human activities ...

Cover Picture and Issue Information

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Cover image: Hunters scatter in the savannah during a collective hunt in the forest of the Democratic Republic of the Congo. In most of Central Africa, traditional hunting practices are being replaced by metal snares, guns and night hunting, impacting wildlife populations and the livelihoods of rural communities.

Transfer function-noise modeling and spatial interpolation to evaluate the risk of extreme (shallow) water-table levels in the Brazilian Cerrados

open access: yes, 2010
Water regimes in the Brazilian Cerrados are sensitive to climatological disturbances and human intervention. The risk that critical water-table levels are exceeded over long periods of time can be estimated by applying stochastic methods in modeling the ...
