Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

Ecology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

ANEMONE Global's First eDNA‐Based Assessment: Insights Toward a Standardized Global Monitoring Network

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Using a standardized eDNA metabarcoding workflow across 12 countries, ANEMONE Global reveals large‐scale patterns in coastal fish biodiversity shaped by habitat complexity, ocean basin, and diel variation. The study demonstrates the feasibility of globally coordinated, high‐resolution marine biodiversity monitoring using eDNA.

Review of the southern African slender stonebashers, genus Heteromormyrus Steindachner 1866 (Teleostei: Mormyridae), with description of six new species

Journal of Fish Biology, Volume 108, Issue 1, Page 128-163, January 2026.
Abstract Recent molecular studies have advanced our knowledge of the taxonomic diversity and generic placement of the slender stonebashers, previously placed in the genus Hippopotamyrus, in southern Africa. These fishes were recently transferred to the genus Heteromormyrus whose range encompasses the Kwanza, Kunene, Okavango, Zambezi, Pungwe and Buzi ...
