Differences in potential reproductive rates of male and female seahorses related to courtship roles
Article Abstract:
Two approaches have been used to estimate the potential reproductive rates of male and female dwarf seahorses, Hippocampus zosterae. Measurements were made of the number of offspring produced per reproductive time when sexually receptive males were unlimited. The reproductive 'time out' for each sex was also determined. Latency to mate was found to be longer for female H. zosterae than for males. Females were not seen to remate during the gestation of their partner, despite being offered sexually receptive males. There is still a need for knowledge about the behavioural or physiological constraints that may be the reason for the prolonged mating latency of female hippocampids.

Faithful pair bonds in wild seahorses, Hippocampus whitei
Article Abstract:
Mating patterns in a Hippocampus whitei population in Sydney Harbor, Australia, were investigated to determine their social organization and reproductive interactions. It is shown that male and female H. whitei form pairs that mate repeatedly and exclusively, with partners greeting each other daily and rejecting interactions with non-partners. These pairs, which are not affected by intra-sexual competition, remain faithful to each other until one partner perishes or disappears.

Fitness consequences of differences in male mating behaviour in relation to female reproductive status in flour beetles
Article Abstract:
Male flour beetles are able to distinguish between virgin and previously mated female beetles. They show a greater preference to mate with virgin females and also copulate more with them, thereby siring more progeny. Olfactory clues are the likely source for their ability to make the distinction. Reasons for siring more progeny while mating with virgin females are discussed.
