Structural Biology![Figure][1] CREDIT: JORE ET AL., NAT. STRUCT. MOL. BIOL. 18 , 10.1038/NSMB.2019 (2011) Just like us, prokaryotes—bacteria and archea—must also protect themselves against pathogenic microbes, such as viruses and plasmids. Prokaryotes use the CRISPR (clustered regularly interspaced short palindromic repeats) system, an adaptive ...

Journal of the Marine Biological Association of the United Kingdom, 1976
There are few teleosts which depart from the ‘classical’ ichthyan body form to such an extent as the seahorse,Hippocampus. In this genus the caudal fin is absent and the tail has become prehensile, the usual function of the caudal fin is taken over by the dorsal and pectoral fins. The dorsal and pectoral fins both have a sculling action, the small anal

Operational Sex Ratios in Seahorses
Behaviour, 1994AbstractContrary to all expectations based on their male pregnancy, recent work shows that seahorses exhibit conventional sex roles in mating competition: male seahorses compete more to obtain eggs than females do to give their eggs away. This suggests that the operational sex ratio (OSR: the relative number of males and females available to mate ...

Some Memories of Stalking the Seahorse
HippocampusABSTRACTEarly influences that led to the development of the cognitive map theory of hippocampal function, and the multiple trace theory, are discussed. Some details are provided, many are left out.
