0:00:02and thus
0:00:08she really to four
0:00:20we focus so i looking at you like or system
0:00:33so i'll component but framework for researches only go system response to disturbances disturbance gonna
0:00:40be environmental issues like acid rain climate change or can be management issues like harvesting
0:00:45other disturbances on an ecosystem
0:00:48the big question is what are the underlying mechanisms that drive ecosystem response to changing
0:00:55chemical and physical climb
0:00:57if we really understand the mechanisms and not just correlations then we can build models
0:01:02and make management decisions to address all sorts of challenges
0:01:07this research allows us to better utilise the natural resources the come from ecosystem services
0:01:13that society is built on and our work has contributed to everything from the re
0:01:19authorisation of the clean air act of nineteen ninety to state laws on management environmental
0:01:24issues to
0:01:27practical management the data database
0:01:30probably the biggest picture take a message comes from these long-term studies probably because they're
0:01:36so rare there is only a handful of whole calibrated what are should research programs
0:01:42particularly with whole watershed manipulations as part of the experimental design
0:01:47to address certain question what we see is that the our understanding on the short
0:01:53term is often not applicable on the long-term and so if we're developing policy local
0:01:59national international policy on a on the environment
0:02:02we really want to know that our understanding of the response of ecosystems and you
0:02:07go system services that society depends on will stand the test of time much of
0:02:12the work is in fact in a in so the answer the question of how
0:02:16does this relate to my life relative to main citizens and managers and the policy
0:02:22litres
0:02:22is this is what's happening in your backyard and this is what supports the economy
0:02:27that we all live so there is a very direct effect a good example would
0:02:31be this long-term their broke study recent years as we come along with it concerns
0:02:36with by low energy the sustainability of the main force to support
0:02:41one of the renewable energy options that we have we turn to bear broke because
0:02:46of the rich database we drive models of nutrient cycling to ask questions about it
0:02:52will increase remove rules have a detrimental affect the long-term productivity
0:02:57so if you do good science and you understand mechanisms then you can both address
0:03:02the questions you started out to answer as well as being well prepared to address
0:03:08undoubtedly the new questions and a new challenges the come for
0:03:12another colleague in the institute george jacobson and i were involved with leading the mains
0:03:18climate future it's no known as a publication which is an assessment of the climate
0:03:22change implications for the state of maine which is had
0:03:26pretty important impact on the public robot regulators managers and different resource sectors understanding how
0:03:34climate change might relate to their everyday lives and has a the area that i'm
0:03:38particularly interested now is how that translates into adaptation
0:03:44climate change is changing i the growing season's longer ice out is earlier all sorts
0:03:49of things are changing in the environment and as people come forward and ask what
0:03:54are these changes in what are the implications for their ecosystems that i'm involved with
0:03:59hopefully some of the science that we do and unquestionably some of the size we
0:04:02do in the climate changes to can address those kinds of concerns
0:04:06our students undergraduate students graduate students are able to be actively involved all your around
0:04:14with both fieldwork work in laboratories working greenhouses and it's are real thrilled to be
0:04:21have them as part of the team
0:04:24and it's even more of a thrill when they go off and they're all around
0:04:27us in society here remain and reflect fondly about a what they learned here and
0:04:32how they're applying it
0:04:34close to a two
