About this episode
It’s a long-held belief that a series of dams in the Snake River in Northwest USA constructed nearly 50 years ago has led to serious declines in Chinook salmon populations. However, new research by Dr David Welch and his team from Kintama Research Services Ltd shows that survival of Chinook salmon measured by a wide range of government agencies has fallen by 65% along the whole North American West Coast over this period. These results have significant implications for informing conservation strategies to protect and restore this important species.

Prof. Mark Kimsey | The Earth’s Blueprint: How Soil Origins Guide Forest Management
Forests are more than just a collection of trees; they are dynamic ecosystems that depend on a variety of factors to thrive. One of the most crucial yet often overlooked components of these ecosystems is the soil. Far from being just a passive foundation, soil is an active, living system that plays a vital role in determining the health and productivity of forests. A recent study by emeritus Professor James Moore of the University of Idaho and his colleagues offers a deep dive into how the geological origins of soil influence its chemical properties, shedding light on the intricate relationships between soil, vegetation, and forest management in the Inland Northwest region of the United States.
Professor Paul Treitz | Mapping Environmental Change: Remote Sensing at the Frontlines of the Canadian Arctic
The Arctic is warming at a rate of three to four times faster than the global average; a phenomenon known as Arctic amplification. This is, in large part, a result of warming atmospheric temperatures causing a decline in snow and ice cover at high latitudes. This, in turn, increases the amount of solar energy absorbed by marine and terrestrial surfaces. As a result, near surface temperatures continue to increase, resulting in a further reduction of snow and ice. This represents a positive feedback where increased temperatures are coupled with a decline in snow and ice cover.
Dr Camille Mellin | Coral Reefs: A Lifeline for Global Nutrition Under Threat
Coral reefs are often admired for their breathtaking beauty and rich biodiversity, but their significance goes far beyond what meets the eye. These vibrant underwater ecosystems are a vital source of food and nutrition for over 500 million people worldwide, particularly in tropical coastal regions where they serve as the backbone of local fisheries. However, coral reefs are under severe threat from the combined forces of climate change and overfishing, posing significant risks to global food security. In a recent Perspective article, Dr Camille Mellin of the University of Adelaide and her colleagues explored how these changes are impacting the nutritional value of fish that live on coral reefs, revealing important insights into the future of food and nutrition security.
Professor Anne Poelina | The Key to Solving Climate Change May Lay in Indigenous Wisdom
In the Kimberley region of Western Australia, Indigenous First Australians are partnering with researchers and together they are pioneering a revolutionary approach to environmental planning and management, called ‘Caring for the River Country’. By blending ancient wisdom, Indigenous First Law and science with Western science, they’re reimagining our relationship with nature and offering a blueprint for global climate action. Professor Anne Poelina at the University of Notre Dame Australia argues that the key to our planet’s future may lie in Indigenous knowledge and wisdom, and ways of conceiving of our natural environment as kin.
