Ecology and Evolution, Volume 15, Issue 10, October 2025.This study used eDNA metabarcoding to detect seasonal fish diversity in the upper Yangtze River, analyzing species composition and functional groups. Multiple diversity indices (α‐diversity, functional, taxonomic, and phylogenetic diversity) were employed to explore seasonal changes in fish communities.

Mechanical shock during egg de-adhesion and post-ovulatory ageing contribute to spontaneous autopolyploidy in white sturgeon culture (Acipenser transmontanus) [PDF]
, 2020 Spontaneous autopolyploidy, a 1.5x increase in genome size resulting from second polar body retention after fertilization, has been documented in cultured sturgeons, with the proportion of spontaneous autopolyploid progeny ranging widely among maternal ...

Measuring critical thermal maximum in aquatic ectotherms: A practical guide
Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2208-2228, October 2025.Abstract Critical thermal limits, commonly quantified as CTmax (maximum) or CTmin (minimum), are core metrics in the thermal biology of aquatic ectotherms. CTmax, in particular, has recently surged in popularity due to its various applications, including understanding and predicting the responses of animals to climate warming.

Journal of Fish Biology, Volume 107, Issue 4, Page 1188-1200, October 2025.Abstract Understanding fish life history is essential for effective management of fisheries, but continuous tracking over lifetime temporal scales can be difficult. Fish otoliths contain a natural biogeochemical record of ambient environmental conditions and habitat use over such scales.

Determining karyotype of sturgeons
Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1995 Karyotype of sturgeons Huso huso, Acipenser stellatus, and Acipenser persicus from southern region of- the Caspian Sea, has been examined by use of blood tissue culture. By counting fifty completely extended metaphase plates, the number of chromosomes in

Two New Sturgeon Species are Susceptible to Acipenser Iridovirus European (AcIV-E) Infection
Pathogens, 2020 We report the first case of Acipenser iridovirus European (AcIV-E) infection in starry sturgeon (Acipenser stellatus) and in sterlet (A. ruthenus) reared in Northern Italy. During 2018, mortality began in A. stellatus and A.
