Delta dynamics: lessons from the Chao Phraya

Delta dynamics: lessons from the Chao Phraya

River deltas occupy about 0.6% of the Earth’s surface area, but contain 4% of the world’s population (about 300,000,000 people). They are also frequently highly fertile, due to the capture of sediment from upstream, and are unique environments that are important for species biodiversity. At the same time they are peculiarly at risk to man-made […]

Aliens in the twilight zone: using robots to study and manage invasive lionfish on Caribbean mesophotic coral ecosystems

Aliens in the twilight zone: using robots to study and manage invasive lionfish on Caribbean mesophotic coral ecosystems

Invasive lionfish threaten native Caribbean marine biodiversity. Lionfish predate unchecked on native fish which, unlike in the lionfish’s native Indo-Pacific, have no evolved defence. Current management relies largely on opportunistic culling by recreational SCUBA divers, yet this only provides local short-term respite because it is shallow (<30m), yet lionfish are abundant in mesophotic coral ecosystems […]

Drinking water ponds in southern Bangladesh: blending traditional and scientific management approaches

Drinking water ponds in southern Bangladesh: blending traditional and scientific management approaches

We are looking for a student with strong interests in freshwater sciences and complex development problems to work with a large transdisciplinary international team. Bangladesh has a profound drinking water crisis which threatens the country’s 160 million inhabitants. Contamination of groundwater with arsenic or salinity has rendered many drinking water sources either unusable or linked […]

Abundance within species’ ranges: understanding species’ responses to environmental change

Abundance within species’ ranges: understanding species’ responses to environmental change

Accelerated climate change and environmental degradation make it necessary to improve our understanding of, and ability to predict, species’ responses to environmental change. The availability of large-scale species distribution databases and information on environmental change, e.g. from satellite measurements, has resulted in thousands of studies using data on species’ geographical ranges to predict their movements […]

Drivers of tropical freshwater biodiversity: a DNA metabarcoding approach

Drivers of tropical freshwater biodiversity: a DNA metabarcoding approach

We are looking for a versatile student with a keen interest in tropical freshwater ecology and conservation, and willing to undertake exciting molecular analyses to define biodiversity. This project will assess the patterns and drivers of freshwater invertebrate diversity in a Bornean river basin. This will be done by combining methods from hydro-ecology, molecular ecology […]

The evolution of mimicry in a changing world: how shifting bumblebee communities affect selection on a colour-polymorphic hoverfly

The evolution of mimicry in a changing world: how shifting bumblebee communities affect selection on a colour-polymorphic hoverfly

Complex species interactions make the impacts of global environmental change difficult to foresee. Understanding the ecological and evolutionary relationships between species, and the way that the fitness of a species is affected by changes in community composition, is essential in order to predict shifts in species distributions and patterns of biodiversity. In this project, we […]

Tracing the Anthropocene, its history and hazards

Tracing the Anthropocene, its history and hazards

You have probably heard of the Anthropocene? But, what is it and when did it actually begin? Scientists are certainly still arguing over the second of these questions. The most recent epoch in Earth’s history is defined by the pollution that Man has created – microplastics, technofossils and synthetic chemicals, to name but three. Radioactive […]

Clean air for all? Air pollution, deprivation and health

Clean air for all? Air pollution, deprivation and health

Poor outdoor air quality, particularly that associated with high concentrations of very fine particles (PM2.5) has been identified globally as a major cause of early mortality. In the UK, DEFRA have identified it as the country’s largest environmental health risk, contributing to long-term illness and shorter life expectancy. This impact appears to be greatest in […]

Maya collapse: solar irradiance and drought

Maya collapse: solar irradiance and drought

The potential role of changes in total solar irradiance (TSI) (sun spots) in driving climatic variability has been widely cited and hotly debated. This is particularly true in the tropical Americas, where a ~200 year irradiance cycle, has been identified in a number of key records, including Lake Chichancanab, in the Maya lowlands of southern […]
