Stephenson and his collaborators, including Whittle, hope to expand the list in the future, adding, for instance, more migrating warblers, some of which are among the hardest, most desirable, and most beautiful birds to see.
These tides include the migrating diurnal tide, migrating semidiurnal tide, and non-migrating DE3 tide.
It is not unheard of in China and Africa, for instance, for a migrating dune to advance on an unsuspecting village at a rate of more than 50 feet a year, blocking off roads and blanketing farmland.
But that's not always the case with migrating flocks.
Such a combination could give rise to co-ordinated/synchronized oscillations in different regions of the cell (for instance two poles of a migrating cell).
This is a representative feature among different migrating cells analyzed.
Birdwatchers, for instance, can see some 140 species of migrating birds pass over Egypt's deserts, twice a year.
For instance, gel shifts and the resulting slowly migrating species have been observed in tripartite motif (TRIM) protein upon cross-linking.
Rare instances of nuclear fragmentation and death have been observed in migrating SOX10-positive ENCDCs (45), although these events are so infrequent that they are unlikely to influence the size of the ENCDC population.
Such variation can, for instance, arise from changes in wind or current velocity for migrating birds and fish, respectively.
