The annual killifish lives in regions with extreme drought. A research group at the University of Basel now reports in “Science” that the early embryogenesis of killifish diverges from that of other ...

The segregation of yolk from the surrounding cytoplasm in the very early fish embryo is a key process for the development of the fish larva. To identify its underlying mechanisms, biologists at the ...

FOR some years now it has been known that the environmental conditions during the development of the fish embryo may exert an influence leading to the number of vertebræ of the offspring becoming ...
