Research
Interests
The
Evolutionary Biology laboratory has three main research themes:
(1)
Tree-of-Life:
The
international Tree-of-Life project
has the goal to reveal the evolutionary relationships among the
1.7 million described species on our planet. In our lab, we use
morphological and DNA sequence data for this purpose and our
trees are not only used for elucidating relationships but also
for reconstructing the evolution of a diverse array of traits
that are important in contemporary evolutionary biology (e.g.,
sexual dimorphisms in Sepsidae, brain size changes in primates).
The main focus taxon of our phylogenetic research is Diptera
(mosquitoes, flies) and we are part of the NSF-funded FlyTree project
that aims to reconstruct the relationships among the 150,000
described species. However, the laboratory has also facilitated
phylogenetic research on corals, fish, crustacean, and birds.
Within Diptera, the main emphasis is currently the Sciomyzoidea
with approximately 2,500 species and the Calyptratae with approximately
18,000 species.
(2)
DNA-based Taxonomy:
Reliable
species identifications and delimitations are important to society
in general and the life sciences in particular. Without species
identifications scientific results cannot be published and the
published information on a species cannot be retrieved from the
literature. With the decline of traditional taxonomy and the
advent of affordable DNA sequencing, the field is currently discussing
to what extent DNA sequences can replace traditional techniques
for species delimitation and identification ('DNA barcoding',
'DNA taxonomy'). We are testing these proposals based on broad
surveys of COI sequence variability in Metazoa. Special
focus is on Sepsidae (Diptera) that is particularly suited for
this purpose because it has many widespread species that live
on several continents. We test whether these widespread species
have large intraspecific, genetic variability and/or contain
cryptic species-level diversity. Fortunately, Sepsidae can be
maintained in the lab and we can also test for reproductive isolation.
This allows us to assess whether morphological or DNA sequence
information are better correlated with species limits. In other
projects, we use DNA sequences for estimating the species richness
of insect samples, matching the immature and adult stages of
dragonflies, and barcoding fish species that are of commercial
interest.
(3)
Evolution of Sepsidae:
The
Sepsidae ('black scavenger flies') is with little more than
300 described species a relatively small and cosmopolitan taxon
of flies that have attracted interest from biologists working
in different fields ranging from the evolution of sexual dimorphisms
over behaviour to developmental biology, and genomics. The main
reasons for this interest are that many species possess intriguing
morphological and behavioural characters, can be easily bred
under laboratory conditions, and have short development times.
In our lab, we extensively study the evolution of sexual dimorphisms
and mating behavior. The data allow us to address how sexual
dimorphisms evolve in response to changes of behaviour and to
test competing theories for the evolution of sexual dimorphisms
via sexual selection (e.g., sexual conflict vs. cryptic female
choice). Our approach is comparative in that we use a phylogenetic
tree for 77 sepsid species and study the behavior and morphology
of a large number of species that we keep in culture (ca. 25
species).
Undergraduate
and Postgraduate Research in the Laboratory:
The
NUS Evolutionary Biology Laboratory in 2004 and has a long-standing
interest in supporting undergraduate and postgraduate research.
Students in our lab have published numerous papers in ISI journals
(see list below *=undergraduate research; #=postgraduate research)
and many of our undergraduate graduates continue with their postgraduate
studies at NUS and/or foreign universities (Harvard University,
University of California at Riverside, University of Zurich,
Sheffield University, Centre National de la Recherche Scientifique
France). Please contact A/P Rudolf Meier if you are interested
in carrying out a research project.
