“…The regulation via lipids may represent a novel sex regulation system that responds to nutritional conditions. In this context, it is interesting to note that Daphnia, a zooplanktonic crustacean, has an environmental sex determination system (Smith, 1915;Banta and Brown, 1929;Hobaek and Larsson, 1990;Kleiven et al, 1992). In Daphnia pulex, which propagates by parthenogenesis under long-day length conditions, the emergence of male with short-day length is associated with an increase in pantothenate levels.…”

Starvation causes female-to-male sex reversal through lipid metabolism in the teleost fish, medaka (Olyzias latipes)

The teleost fish, medaka (Oryzias latipes), employs the XX/XY genetic sex determination system. We show here that the phenotypic sex of medaka is affected by changes in lipid metabolism. Medaka larvae subjected to 5 days of starvation underwent female-to-male sex reversal. Metabolomic and RT-qPCR analyses indicated that pantothenate metabolism was suppressed by starvation. Consistently, inhibiting the pantothenate metabolic pathway caused sex reversal. The final metabolite in this pathway is coenzyme A, an essential factor for lipogenesis. Inhibiting fatty acid synthesis, the first step of lipogenesis, also caused sex reversal. The expression of dmrt1, a critical gene for male development, was suppressed by starvation, and a dmrt1 (Δ13) mutant did not show sex reversal under starvation. Collectively, these results indicate that fatty acid synthesis is involved in female-to-male sex reversal through ectopic expression of male gene dmrt1 under starvation.

“…It should be noted that not only has it been imipossible specially to demonstrate a direct density effect in Daphnia, but that all of the results which have been explained by a postulated density effect can equally be explained by postulating a change in food supply (Banta & Brown 1929;Mortimer 1936). …”

“…If it had been possible to show that these animals differ in physiology from animals raised in fresh medium, then the direct densitv effect would have been demonstrated. None of these attempts succeeded (Banta et al 1939;Banta & Brown 1929). It has therefore been postulated that the direct density effect in Cladocera depends on some volatile or ephemeral substance in the medium (Banta & Brown 1929;Pratt 1943).…”

“…It is possible that bacteria and protozoans whose populations were enhanced during the course of the study may have been competing for food with the copepods in the aquaria, thus imposing a food stress even though the copepod populations were low. It is also possible that a build-up of metabolites inhibited egg production, a phenomenon which has been noted in Daphnia populations by Banta and Brown (1929) and Pratt (1943). Although there was an increase in ~Qg production toward the end of the study, there were no subsequent increases in the immature stages.…”
