Regarding the evolutionary rates of the feeding apparatus, the Mesozoic species act as the ‘watershed’ of the history of lampreys (Supplementary Discussion). The relative rates along the branches downward and crownward to themselves greatly differ, with the former almost ten times the latter (Sup...

In total, 62% of the freshwater fish species in Flanders was considered extinct or threatened. This is higher than neighbouring regions and Europe as a whole (44%). This new Red List of freshwater fishes in Flanders can be used to inform conservation actions. 展开 ...
The movement was characterised by displacements in the vicinity of the upstream gates of the lock and from one side of the lock to the other. One radio tagged lamprey that passed through the lock and migrated upstream to the Derwent showed ‘fallback’ behaviour, moving downstream through the ...
We discovered massive transfers of a DNA transposon, a Tc1 element encoding a transposase, between multiple teleost fishes and lampreys that last shared a common ancestor over 500 Ma. Members of this group of Tc1 elements were found to exhibit a mosaic phylogenetic distribution, yet their ...
The main objective was to provide for the first time harmonized occurrence traits for European lampreys and fishes in both longitudinal and lateral dimensions of floodplain river systems in a Fish Region Index (FRI) and Floodplain Fish Index (FFI), respectively. Altogether 163 lamprey and fish ...
However, the ultrastructural characteristics and distribution of their epithelial cell types [ammocoete mitochondria-rich (MR) cell, intercalated MR cell, chloride cell and pavement cell] differ in several respects from those of teleosts. The ultrastructural characteristics of these cells are distinctive...
The choice of a morphogenetic pathway can be influenced by the level of individual heterozygosity, changes in the copy numbers of certain DNA sequences, heteroplasmy, and the presence of several allelic variants in the genes that strongly affect the phenotype. A cyclic character is often observed ...
