About this episode
The marine environment houses complex types of ecosystems that provide vital services and habitat to aquatic life. Areas of the seafloor where rocky outcrops are present, such as reefs and gravel beds, are some of the rarest marine habitats. Also known as ‘hard substrate habitats’ these ecosystems are under increasing pressure from fishing, eutrophication, climate change, and coastal management. Though hard substrates are protected in the European Union, we are unable to manage them effectively because maps describing their location and dimensions are inaccurate. In a review paper, Dr Svenja Papenmeier [Sven-yah Pah-pan-my-er] of Germany’s Leibniz Institute for Baltic Sea Research Warnemünde summarises existing rules for mapping substrate habitats, and describes new and potentially ground-breaking mapping techniques.

A welcome sign of a change in seasons, the year’s first flowers usher in the start of spring. Yet, as the climate warms, some flowers are blooming earlier. Since plants respond to environmental cues, such as temperature, shifts in their annual development has long been considered an effect of climate change. However, significant warming does not always lead to earlier flowering.
The Geological History of Once-Glaciated Regions Affects Current and Future Earth Surface Processes | Dr Alison Anders
Over the past few millions of years, a succession of ice ages has profoundly influenced the geology of Earth’s northerly latitudes. These past events continue to influence our lives today – particularly in the fertile regions we now rely on for agriculture. By tracing the advances and retreats of ice sheets, Dr Alison Anders at the University of Illinois is gaining important new insights into how the landscapes and ecosystems of these regions are intrinsically linked to the geological past. Her team is also revealing how these areas are responding to a changing climate, and to complex human relationships with the land.
Revealing How Ocean Chemistry Controlled Earth’s Ancient Atmosphere and Microbial Evolution | Dr Romain Guilbaud
Important clues buried within ancient rocks that were deposited on the ocean floor around one billion of years ago could help scientists understand the evolutionary history of life on Earth. Dr Romain Guilbaud and an international team of researchers from the UK and China analysed the chemical composition of these rocky sediments from the Huainan Basin in North China. Their findings demonstrate how changes in ocean chemistry occurring between one billion and 800 million years ago strongly limited the production of atmospheric oxygen, which is a necessary prerequisite for the planet to host complex life.
Beneath our feet lies one of the most biodiverse habitats imaginable – the soil. These highly active underground microbial communities are vital to ecosystem health; they cycle nutrients, form soil structure, and decompose organic matter, among many other functions. The type of microbes that colonise soil is determined by the local plant community and climatic variables, both of which are rapidly changing due to human activity. In a recent study, Dr Carl Rosier of the University of Delaware has explored how urban development disturbs the environmental cycles that influence the types of microbes found in various soil habitats.
