Modelling the future of coastal soft cliffs under changing climate

Applications are invited for a PhD studentship within the NERC-ENVISION Doctoral Training Partnership with a project entitled: “Modelling the future of coastal soft cliffs under changing climate”. Coastal soft cliffs are extremely important components of coastal environments worldwide. Their retreat is a global problem that threatens coastal communities. Climate change affects soft cliffs retreat; however, […]

Ecosystem functions of tropical filter-feeders under environmental

Mussels, bryozoans and sponges are sessile filter-feeders that are known to fulfil important ecosystem functions in temperate freshwater habitats, such as water clearance, nutrient cycling and promotion of benthic biodiversity; yet in tropical freshwaters, their functional roles are poorly understood. At the same time, anthropogenic pressures, including deforestation and land-use change, have caused tropical filter-feeding […]

In from the cold: how are winter plankton communities changing with the climate?

Lake ecosystems host diverse communities of organisms which show great variation over seasonal, year-to-year and decadal timescales. Growing evidence demonstrates that these communities are already being impacted by climate change, but much existing research has focused on the ecology of spring and summer communities, with winter communities receiving less attention. We know that winters are […]

The impact of climate change on the thermal ecology of cold-adapted butterflies

The project will investigate how increasing temperatures are affecting northern butterflies in the UK, and test the potential for managing habitats to promote climate change adaptation.  It provides an exciting opportunity for an ecologist, with an interest in conservation and a desire to undertake crucial research using state of the art techniques in remote sensing […]

Effects of seabird nutrient inputs on the productivity of coral reef fish communities

How coral reefs can sustain their extreme biomass of large reef fishes has continued to puzzle scientists. By living fast and dying young, small, bottom-dwelling (‘cryptobenthic’) reef fishes have been suggested as an important part of coral reef productivity, fuelling the foodweb. Yet, cryptobenthic fish communities are strongly dependent on environmental conditions, and as such […]

Why are there so few C2 grasses?

The vast majority of plant species use C3 photosynthesis. However, a turbo-charged form of photosynthesis called C4 evolved independently in nearly 70 lineages and is used by our most productive food and bioenergy crops. C4 photosynthesis evolved repeatedly from the ancestral C3 type via a series of modifications to leaf biochemistry and anatomy, which inevitably […]

Restoring for a resilient future: Woodland community assembly trajectories in the face of multiple stressors

You will be based at UKCEH Bangor and Bangor University, joining a dynamic group of forest ecosystem, climate change and air pollution researchers, based in the Environment Centre Wales. You will make use of world-leading pollution control facilities, including a field-release ozone system and the solar domes (https://www.ceh.ac.uk/our-science/research-facilities/solardomes-and-ozone-field-release-system). The work includes relating detailed ecophysiological measures […]

Tracing the heat signature of Atlantic Water through the GIN seas and its impact on Arctic ice and climate.

Extreme weather such as floods, heat waves, unusually cold harsh winters are increasingly prevalent across the Northern Hemisphere. For instance, the Thames barrier, designed to prevent flooding of the London floodplain from a combination of high tides and storm surges has been raised 199 times since 1982, well in excess of the originally anticipated 1-2 […]
