Candidate-source decisions
Investigating the Expression and Function of HIF-1alpha in Neocaridina davidi During Embryo Cleavage Stage
Included as direct embryo gene-knockdown evidence, but it assigned no oxygen treatment and reported no dissolved-oxygen measurement, survival curve or reproductive oxygen endpoint.
An ecophysiological approach to improving health outcomes of ornamental shrimp during aquarium trade and transportation
Useful review of oxygen and transport gaps, but not an assigned chronic oxygen experiment.
Search outcome
A direct HIF-1alpha embryo knockdown study adds a molecular cleavage result but assigned no oxygen treatment and measured no dissolved oxygen. No controlled dissolved-oxygen treatment series establishing survival, growth or reproduction limits was located. The gap remains open.
