DESCRIPTION:Mathematical ecology is a science that applies a b
road range of mathematical and computational techn
iques to problems arising in ecology with the goal
to better understand how animal and plant species
interact between themselves and with their natura
l environment. I will begin with a brief overview
of problems that have long been a focus of attenti
on in ecology. In the first part of my talk\, I wi
ll then consider in some detail mathematical appro
aches to the problem of ecological monitoring in c
omplex multiscale environments. This problem has i
mportant implications\, in particular in the conte
xt of sustainable agriculture\, groundwater qualit
y\, and biological invasions. I will show that eac
h of the spatial scales may require a different mo
delling/computational technique\, but reliable mon
itoring is only possible when the inter-scale coup
ling is taken into account. In the second part of
my talk\, I will argue that biological species are
not only controlled by their environment but also
can change the environment quite significantly. I
n order to demonstrate this\, I will consider the
dynamics of marine plankton under the global warmi
ng to show that it may result in the oxygen deplet
ion on a global scale\, with apparently disastrous
consequence for animals and humans.
