New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years.

Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.

A review of almost 1000 studies on the effects of climate change and extreme weather events on rivers around the world has found an overall negative effect on water quality in rivers globally. An international team of experts sourced from every continent, conducted between 2000-2022.

Many of today's artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology -- ecology -- could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible. The paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change impacts.

A collaboration of ecologists and art historians has demonstrated that landscape paintings from more than 150 years ago can advance environmental science.

Researchers are assessing the efficacy of shark sanctuaries by developing a modeling system that utilizes publicly accessible fishing data to determine shark catch and mortality rates. Their findings represent an important step in utilizing data science to tackle oceanic conservation challenges.

More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.

A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.

The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.

A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.

A new report presents major findings on the gravity of impacts from invasive alien species on our planet.

Patent-pending adhesive formulations developed from fully sustainable, bio-based components establish bonds that grow stronger when underwater or exposed to wet conditions.

An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.

New research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa. The study reveals how environmental changes disrupted mammal communities and highlights the urgent need for targeted conservation efforts to protect vulnerable species.

A study shows nest temperatures affect leatherback hatchling shape, performance and nest success. Lower temperatures produced longer hatchlings; highest temperatures produced hatchlings with thicker body depths. Hatchlings from the highest nest temperatures had shorter flippers. Righting response (ability to flip over) scores were significantly lower in hatchlings from hotter nests. Hatchlings that were smaller and/or had a larger body depth struggled to right themselves. The leatherback turtle nests in this study also had an overall lower hatching success (45 percent) than loggerhead (73 percent) and green sea turtles (70 percent).

New research shows that, in addition to trees, humble grasses also play an essential role in capturing carbon.

As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
