Research
interests Evolution of
social and mating systems of neotropical rodents In My current
research is focussed on the evolution of social and mating systems in
the
Caviinae, the true guinea pigs. I am conducting field studies on
closely
related species of wild guinea pigs which inhabit ecologically
different
habitats to determine the ultimate factors that have shaped the
evolution of
their divergent social and mating systems.
I study
natural
populations of wild cavies (Cavia aperea)
in Applied
methods
are radio-telemetry, direct observations, mark - recapture and
the
collection of
different ecological parameters, including climatological data and the
mapping
of habitat structure.
By investigating the impact of different ecological factors like the habitat structure, food availability and predation risk on the development of divergent social and mating systems within the Caviinae I am attempting to reveal general rules for the social evolution of rodents. Publications Asher,

Personal
background Being curious about different cultures, I visited numerous foreign countries during university years. Apart from two trips to Throughout
my biological studies, I focussed on zoology, and in 1999 I completed
my Diplom
(Master's) on the behavioural ecology of wild guinea pigs (Cavia
aperea),
under supervision of Prof. Dr. Norbert Sachser. The fieldwork
underlying this
study was conducted in Since 2000, I am PhD
