Revealing human impacts through time in the Brazilian Pantanal using integrated lake sediment analyses

The Pantanal is the world’s largest tropical wetland and home to numerous endangered and threatened species. It is also increasingly impacted by human activities, particularly cattle ranching. In recent years, it has suffered severe wildfires and altered hydrology. The impacts of these changes on the Pantanal are understudied, yet have global significance given the wide […]

A scent of biodiversity – environmental volatile organic compounds to monitor biotic interactions

Monitoring biodiversity is a major research focus, with the current upsurge in initiatives to finance biodiversity conservation (e.g. Target 19, Kunming–Montreal CBD). Measurements must be transparent, repeatable, efficient and auditable. Accordingly, researchers have developed visual (imagery), auditory (sound recording), genetic (eDNA) and structural (LiDAR) sensing technologies for biodiversity assessments. These focus on species diversity or […]

Why do populations fail to adapt to environmental change?

Fish and water scene

There are myriad examples of amazing evolutionary adaptations, from the beaks of finches to antimicrobial resistance, that have been shaped by selection arising from natural processes or the effects of humans on the environment. These have been studied in detail, and can make evolutionary adaptation seem inevitable. But natural selection is not all powerful: sometimes […]

Evaluating the pre and syn-collapse conditions of rainfall-triggered landslides in Indonesia: steps toward improved forecasting

Image of landslide

Landslides are a persistent and widespread geohazard in Indonesia, causing tens to hundreds of deaths and widespread infrastructure damage on a yearly basis (e.g. Froude and Petley 2018). Landslide triggers are multiple and complex, ranging from seismic shaking and volcanic activity to intense rainstorms. Rainfall-triggered landslides are the most frequent and widely distributed. The intense […]

Freshwater storage at the “roof of the world” under climate change

Satalite image

The Tibetan Plateau, commonly known as the “the roof of the world”, supplies freshwater for nearly two billion people. Water storage is crucial in determining hydrologic transport and water availability but is highly sensitive to climate change. Water storage change is a critical indicator of vulnerability of the “Asian Water Tower”. Despite its importance, the […]

Accelerating phosphorus and nutrient cycling in the Greenland Arctic ecosystem Soils

Glacier

PhD Study: At the Global Frontier of Climate Change and Nutrient Cycling   The fragile Arctic ecosystems are changing rapidly due to global warming, as glaciers retreat, they are revealing arctic soils under the process called ‘greening’. These soils store substantial amounts of organic matter and nutrients, which may become bioavailable under higher temperatures and changing […]

Early warning of reservoir dam failure: harnessing novel ground imaging and machine learning technologies for enhanced hazard assessment

This is an exciting opportunity to explore deep learning (DL) methods, in combination with geophysical and hydro-mechanical models, to extract information on the stability of dams and other earthworks. The collapse of the auxiliary spillway of the Toddbrook Dam following heavy rain during summer 2019 brought significant public attention to potential hazards from failure of […]

Carbon cycling in freshwater lakes; identifying the who, what, where and when.

Algal blooms in freshwaters are happening with increasing frequency due to climate change and input of nutrients. Lake ecosystems may be severely impacted by blooms, particularly the microbial food web. Many of the algae which bloom produce large quantities of photosynthetic fixed carbon which are exudated throughout their growth cycle as dissolved organic carbon (DOC), […]
