Mark Rowland’s research
concerns the conditional expression of alternative minor and
major male phenotypes in scarab beetles. His ongoing projects
are: (1) Macroevolutionary behavior of horn expression thresholds
as a function of defined phylogenetic scale in the dynastine
genus Xylotrupes (Rowland 2003); (2) Development of
a coherent quantitative system that effectively models demographic
and evolutionary change in the expression of the alternative
phenotypes that are produced by qualitatively different non-linear
horn allometries (Rowland et al. 2005; Rowland and
Qualls 2005); (3) Exploration of the phylogenetic patterns of
male horn dimorphism in scarab dung beetles to determine how
and why alternative intrasexual phenotypes might arise and evolve
in relation to ecological factors such as the social environment
in which they are framed. |
