DOWNSTREAM MIGRATION: PROBLEMS AND FACILITIES [PDF]
Knowledge and Management of Aquatic Ecosystems, 2002 Downstream fish passage technology is much less advanced than it is for upstream fish passage facilities. This is simply due to the fact that efforts to re-establish free movement for migrating fish began with the construction of upstream fish passage facilities, and that downstream migration problems have only been recognised and addressed more ...

Toddler signaling regulates mesodermal cell migration downstream of Nodal signaling
eLife, 2017 Toddler/Apela/Elabela is a conserved secreted peptide that regulates mesendoderm development during zebrafish gastrulation. Two non-exclusive models have been proposed to explain Toddler function.

Knowledge and Management of Aquatic Ecosystems, 2023 Downstream migrating fish can be strongly affected by hydroelectric facilities. To set up adapted mitigation measures, it is important to identify these impacts (e.g. induced mortality rates).

Isoprenoids Control Germ Cell Migration Downstream of HMGCoA Reductase [PDF]
Developmental Cell, 2004 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCoAr) provides attractive cues to Drosophila germ cells, guiding them toward the embryonic gonad. However, it remains unclear how HMGCoAr mediates this attraction. In a genomic analysis of the HMGCoAr pathway, we found that the fly genome lacks several enzymes required for cholesterol biosynthesis ...

Downstream fish passage at small-scale hydropower plants: Turbine or bypass?
Frontiers in Environmental Science, 2023 Introduction: Hydropower plants are frequently equipped with physical and behavioral fish protection barriers to prevent downstream moving fish from harmful turbine passage and to guide them to alternative bypasses.

An end-to-end software solution for the analysis of high-throughput single-cell migration data [PDF]
, 2017 The systematic study of single-cell migration requires the availability of software for assisting data inspection, quality control and analysis. This is especially important for high-throughput experiments, where multiple biological conditions are tested
