Estrogen masculinizes neural pathways and sex-specific behaviors.

30 Sep 2009 Sex hormones are essential for neural circuit development and sex-specific behaviors. Male behaviors require both testosterone and estrogen, but it is unclear how the two hormonal pathways intersect. Circulating testosterone activates the androgen ... Read more...

Chemical polymorphism and chemosensory recognition between Iberolacerta monticola lizard color morphs.

29 Sep 2009 In the lizard Iberolacerta monticola, there are 2 discrete color morphs ("blue" vs. "green") that seem to have alternative reproductive strategies. Because scent marking of territories and chemoreception are important in social organization of these ... Read more...

Hormonal anticipation of territorial challenges in cichlid fish.

30 Aug 2009 In many territorial species androgens respond to social interactions. This response has been interpreted as a mechanism for adjusting aggressive motivation to a changing social environment. Therefore, it would be adaptive to anticipate social ... Read more...
