The workshop “Spatio-Temporal
Dynamics in Ecology” was hosted by the Lorentz Center in the
period December 8–12, 2014. It brought together leading scientists working
on the interface of Ecology, Mathematics and Physics, who presented the
state of the art in population and ecosystem dynamics, as well as in
animal behavior. Through these talks and associated discussions, the organizers
aimed to outline research areas where cross-fertilization is much
needed.
The ecosystem
dynamics theme benefited from the combined expertise of established
ecologists, mathematical modelers and dynamicists present
at the meeting. The presentations covered timely topics such as the
prediction of critical transitions and catastrophic phenomena, the intertwining
of biodiversity and complexity, the transformative role of data in mathematical
practice, and the modeling and analysis of spatial processes across
Ecology. The extensive discussions focused on the interplay between field and
modeling reality, the integration of fieldwork into mathematical
practice, the juxtaposition of universal mechanisms to
idiosyncrasies of experimental models and, additionally, the importance of
interdisciplinary training and practice for young and aspiring scientists. Many
smaller groups also got the opportunity to discuss hands-on work and
collaborative projects.
Broadly put, the workshop highlighted a
number of trends, as well as of themes where synergy can be mutually
beneficial.
1 There is a pressing need to develop mathematical
tools that can deal with large ecosystems and vast modeling uncertainties. The
coupling of Mathematical Analysis to Statistics and Algebra has major
potential to make an impact in that direction.
2 Within the topic of pattern formation, an interesting
discussion developed around the topic of wave length changes in regular
patterns in a range of ecosystems, in particular around the question whether
wave length changes could be used to indicate the decline of resilience in the
face of (globally) changing environmental conditions.
3 Mathematical Ecology must account for
socio-economic externalities and feedbacks even more than today. The link
between Ecology and Climate Science must also be strengthened.
4 There is significant misunderstanding with regard of
the use of the term Levy walks to describe animal movements and that there is a
need for a paper that clearly outlines the different viewpoints in favor and
against the Levy hypothesis, and that provides an overarching perspective that
unites the field.
5 Modeling is being transformed by the emergence of
agent-based models and computational upscaling. This trend is
important, as models at the individual level reflect mechanisms
and demographic heterogeneities more transparently.
6 Despite intensive efforts,
spatial processes and multi-species interactions remain largely
unexplored and poorly understood. Both continue to resonate well with the
interests of the dynamic community.
7 Transdisciplinarity and knowledge transfer are necessary to deal with
large-scale problems. This highlights the importance
of emerging interdisciplinary training networks, as well as of
outreach efforts of individual researchers.
The separate
meetings held during the workshop were essential to putting together such a
helicopter view, as well as to start giving shape to a unified
theory. Currently, this breakout group is working on two papers, one of
which has reached a first draft version.
