Key Research Interests

My research focuses on the impacts of environmental change on vegetation and ecosystem processes (particularly nutrient cycling and fluxes) and on how these ecosystem processes are affected by plant community structure

Current key questions include:

• Effects of environmental change on Arctic vegetation and biogeochemical cycling
• Effects of Arctic plants, parasitic plants and biodiversity on ecosystem function
• Effects of pollutant nitrogen deposition on plant biodiversity, nutrient cycling and plant nutrient acquisition

Dr Gareth Phoenix is APS liaison for the Environmental Science degree, ad-hoc member of the Teaching Committee and co-ordinates APS118 tutorials for Environmental Science students.

At level 1, I teach APS124 (Ecosystems and Environmental Change). My main research interests are the impacts of global change on ecosystems, and this course gives me a chance to teach this fascinating area to new students. I cover a diversity of topics, from how past climates have influenced the development of ecosystems in the UK, to the threats of contemporary climate change. The latter includes findings from some of our own work undertaken here in APS. The APS118 and APS222 tutorials are also an excellent opportunity to develop discussion and debate on these topics as well as helping students develop generic skills in writing, critical analysis, experimental design and oral communication.

My own research includes work on Peak District ecosystems, and at level 2, we use this area to study the interaction between ecosystems and the environment in APS246 (Plant Habitats and Distributions). Here we use a combination of lectures, laboratory classes and field visits. These ideas are expanded further in APS273 (Population and Community Ecology 2) where I teach how plant diversity and the composition of species influence how an ecosystem functions (for instance, the ecosystem’s capacity to sequester carbon from the atmosphere, cycle nutrients or trap pollutants).

My key area of research – Arctic ecosystems and environmental change – informs my teaching at level 3. Here, in addition to lecturing on plant adaptations to arctic environments in APS325 (Life in Extreme Environments), I teach on the Arctic Ecosystems field course (APS343) to Abisko in northern Sweden. The research station we use is also the home to many of my field experiments and so in addition to teaching more generally about Arctic ecosystems, this course offers students the opportunity to learn about, and work on, on-going Arctic research experiments.

The topics of global change, biodiversity and ecosystem functioning are also covered in research projects and dissertations at level 3 (APS330 and 331) and at level 4 (APS402 & 406), where my students address questions concerning the impacts of pollution and climate change (e.g. drought, warming) on plant diversity and ecosystem functioning.
