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.

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.

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.
