	Differential effects of 11-ketotestosterone on dimorphic traits in a teleost with alternative male reproductive morphs. Hormones and behavior, Vol. 47, No. 5. (May 2005), pp. 523-531. by Jonathan S. Lee, Andrew H. Bass posted to testosterone teleost sex plasticity neuroanatomy fish androgen by ppouso on 2009-09-24 00:24:23 Abstract Copy My Attachments My Copy Abstract Species with dimorphic males typically have one morph (type I) associated with territoriality and courtship, and another morph (type II) associated with cuckoldry. In teleost fishes, type I males generally have higher levels of the androgen 11-ketotestosterone (KT) than type II males. Is KT causal to phenotypic differences between morphs? We investigated this question in the midshipman fish (Porichthys notatus) in which type I males have detectable levels of KT during the breeding season, whereas levels in type II males are ...

	Aromatase activity in hindbrain vocal control region of a teleost fish: divergence amoung males with alternative reproductive tactics posted to vocalization teleost fish aromatase by ppouso on 2009-09-01 21:10:42 Abstract Copy My Attachments My Copy Abstract ype I male midshipman fish acoustically court females, whereas type II males do not but instead sneak or satellite spawn to compete with type I males for fertilizations. 'Singing' type I males diverge from type II males and females in the organization of an expansive hindbrain pacemaker–motoneuron circuit that establishes the physical attributes of vocalizations. Here, levels of aromatase activity were determined in homogenates of brain by measuring the conversion of 3H-androstenedione (AE) to 3H-oestrone (E1) and 3H-oestradiol (E2). Levels were ...
