In species in which intense intermale competition for the access to females is present males of lower competitive ability may adopt alternative reproductive tactics (ART) to get access to mates. These ART translate in many cases into male sexual polymorphism, with individuals following distinctly different tactics. Usually two alternative male morphs can be recognized in species with ART: (1) b...

http://dx.doi.org/10.1016/j.anbehav.2016.01.006 0003-3472/© 2016 The Association for the Study of A Reproductive and agonistic behaviours typically diverge between individuals pursuing alternative reproductive tactics (ARTs). When tactics are fixed for life, evolutionary theory predicts that the relative frequencies of alternative male genotypes are stabilized in a population by negative freque...

Abstract Given a contact structure on manifold V together with supporting open book decomposition, Bourgeois gave an explicit construction of $$V \times {\mathbb {T}}^2$$ V × T 2 . We prove that all such structure...
