1. Population Histories and Evolutions of Endemic Insects in Taiwan.

I am interested in population histories of Taiwanese insects, particularly insects with attractive behaviours and bizarre structures. My graduate study was on the contemporary population structure of an endemic Formosan damselfly, Euphaea formosa. Little genetic structuring was revealed by both mitochondrial and nuclear markers, which is concordant with observed substantial dispersal in this species. Two distinct lineages and historical demographic expansions were inferred using coalescent simulations. The global climate fluctuations during Late Pleistocene were likely responsible for the historical multiple introductions and demographic expansions of the Formosan damselfly through alteration of continental connections and changes of favorite habitats.

2. Genetic and Morphological Studies of Formosan Stag Beetle, Lucanus formosanus.

We also conducted genetic as well as morphological studies on Formosan stag beetle, Lucanus formosanus, which is traditionally believed to exhibit distinct morphological variations among populations. Despite rampant gene flows among populations around the central mountain range (CMR) were inferred using neutral molecular markers, significant morphological divergence was found among populations. Selections on certain genes (or traits) while the others are allowed to be exchanged among populations is the paradigm of ecological speciation or parapatric speciation, which is currently resurrected. The observed different population densities and co-dwellers could be the driving forces of the morphological divergence in the face of substantial gene flows in the Formosan stag beetle.
