Climate change is reducing global river water quality      (via sciencedaily.com)     Original source 

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.

Ecology and artificial intelligence: Stronger together      (via sciencedaily.com) 

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.

Art, science merge in study of 19th-century landscape paintings' ecological integrity      (via sciencedaily.com) 

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

'A crab is never just a crab'      (via sciencedaily.com)     Original source 

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.

Scientists find evidence of sea star species hybridization      (via sciencedaily.com) 

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.

Beaver activity in the Arctic increases emission of methane greenhouse gas      (via sciencedaily.com)     Original source 

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.

Lack of evidence hampers progress on corporate-led ecosystem restoration      (via sciencedaily.com) 

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.

Echoes of extinctions: Novel method unearths disruptions in mammal trait-environment relationships      (via sciencedaily.com)     Original source 

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.

New research highlights opportunities to protect carbon and communities from forest fires      (via sciencedaily.com)     Original source 

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.

Fossil spines reveal deep sea's past      (via sciencedaily.com)     Original source 

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.

Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.

Bit by bit, microplastics from tires are polluting our waterways      (via sciencedaily.com) 

Urban stormwater particles from tire wear were the most prevalent microplastic a new study has found. The study showed that in stormwater runoff during rain approximately 19 out of every 20 microplastics collected were tire wear particles with anywhere from 2 to 59 particles per liter of water. Tire rubber contains up to 2500 chemicals with the contaminants that leach from tires considered more toxic to bacteria and microalgae than other plastic polymers.

Extreme El Niño weather saw South America's forest carbon sink switch off      (via sciencedaily.com)     Original source 

Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.
