Research interests
Over the last 20 years or so, we are witnessing a conceptual revolution
in the field of population biology and ecological modeling, which was stimulated
by the rapid development of advanced new scientific tools such and individual-based,
spatially explicit population models, and Geographic Information Systems
(GIS). There is much work to be done in developing our understanding of
the new "spatial ecology", and my research program is driven by an interest
in this topic. My mayor research interest are
-
understanding the long-term dynamics of semiarid
plant communities,
-
spatially explicit population viability analysis (PVA) of
large
carnivore populations,
-
integrating approaches of landscape ecology
and population modeling.
My primary goal are (1) to broaden the theory of population and community
ecology and to integrate them with landscape ecology to encompass an explicit
consideration of spatially distributed processes, and (2) to develop methods
to adapt models optimally for ecological applications, such as PVA. This
involves several complementary approaches:
-
development of
individual-based
and/or
spatially-explicit
simulation models as
experimental tools for studying the dynamics of populations or communities (Wiegand
et al. 1995,
1998a, 1998b,
1999,
2004,
2005,
2006),
-
development of a modeling strategy which facilitates the inclusion
of the biological information in an optimal way in a model (Wiegand et
al. 2004), the
pattern-oriented
modeling strategy (Grimm et al. 1996,
Wiegand et al.
2003;
Grimm et al. 2005), and
-
spatial
pattern analysis for characterizing pattern over a range of spatial
and temporal scales as a means of identifying critical, pattern forming
ecological processes (Wiegand and Moloney
2004,
Wiegand et al. 2006,
Wiegand et al.
2007 a,

c).
