Morphology, molecules and mating behavior : an integrative study of population divergence and speciation in widespread sepsid flies (Sepsidae: Diptera)


Puniamoorthy, Nalini. Morphology, molecules and mating behavior : an integrative study of population divergence and speciation in widespread sepsid flies (Sepsidae: Diptera). 2013, University of Zurich, Faculty of Science.

Abstract

The work presented in this dissertation explores processes of selection and speciation acting on diverging populations in two widespread sepsid species (Sepsidae: Diptera). The main focus was on investigating sexual selection, sexual size dimorphism (SSD) and incipient speciation in the nearctic and palaearctic species Sepsis punctum (Fabricius 1794) (Chapters 1-4). In addition, divergence in reproductive behavior and morphology was also addressed in the neotropical species Archisepsis diversiformis (Ozerov 1993) (Chapter 5).
