People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Aquaculture Research, Volume 2025, Issue 1, 2025.Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.
