An isothermal workflow for low‐cost and PCR‐free field‐based community metabarcoding
Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1413-1424, July 2025.Abstract DNA metabarcoding has revolutionized our ability to monitor ecosystems. However, the method is still rarely used in developing countries where resources are limited and fieldwork is challenging. To overcome this limitation, we designed a comprehensive workflow allowing rapid community metabarcoding with minimum, self‐manufacturable equipment ...

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.ABSTRACT Ornamental aquaculture and fishkeeping are very popular with millions of enthusiasts worldwide. The number of newly imported fish species for ornamental purposes grew slowly from World War I until the 1980s. It then exponentially increased until now with more than 7900 species and a large number of scientifically undescribed morphotypes.

Effect of different oxygen levels on growth performance, stress response and oxygen consumption in two weight groups of great sturgeon Huso huso [PDF]
, 2013 In the present study, different oxygen levels were examined in two weight groups of great sturgeon Huso huso including small size (with initial weight 280.9 ± 49.2 g) and large size (with initial weight 1217.9 ± 138.1 g). The fish were kept in hypoxia (2-

Global Change Biology, Volume 30, Issue 11, November 2024.Combining published data gathered from the field and in the laboratory, we examined how temperature impacts North American sturgeon to gauge how these threatened and endangered species will fare in an increasingly warming world. We found that, in response to prolonged warming, North American sturgeon can increase their upper thermal limit more so than ...
