Oakland University Professor Scott Tiegs is a co-author on a new study that examines how glacier loss, driven by global warming, affects glacier-fed river ecosystems. The study was published March 15 in the journal Nature Climate Change.
Tiegs was part of an international team of researchers led by the University of Leeds (United Kingdom) that measured organic matter decomposition rates in mountain rivers in six countries and four continents. The study found that as glaciers melt, the rivers downstream support higher rates of organic matter decomposition, a major process in the global carbon cycle. This discovery could help researchers better predict how river ecosystems will change as mountains continue to lose ice due to global warming.

The Open Burning of Waste Poses Grave Health Risks To Millions
We’re generating more waste than at any other time in history what with a greatly increased global population, rampant consumerism and the wanton use of single-use items like plastic bags and wrappings.
Most of us rarely spare a thought to what happens to our household waste once we put it in the bin, but much of it gets simply burned. And the practice of burning waste poses grave health risks to tens of millions of people around the world, according to a new report, which is the first study of its kind.
Melting glaciers could be triggering a ‘feedback process’ that causes further climate change, according to new research.
An international research team led by the University has for the first time linked glacier-fed mountain rivers with higher rates of plant material decomposition, a major process in the global carbon cycle.
As mountain glaciers melt, water is channelled into rivers downstream. But with global warming accelerating the loss of glaciers, rivers have warmer water temperatures and are less prone to variable water flow and sediment movement. These conditions are then much more favourable for fungi to establish and grow.
Fungi living in these rivers decompose organic matter such as plant leaves and wood, eventually leading to the release of carbon dioxide into the air. The process a key part of global river carbon cycling has now been measured in 57 rivers in six mountain ranges across the world, in Austria, Ecuador, France, New Zealand, Norway and the Unit

Universities in emerging economies are improving at a faster rate than universities from developed countries, according to results from the 2021
Times Higher Education rankings.
This stellar performance is being driven by institutions from Pakistan, Russia and China, the latter accounting for an unprecedented clean sweep of the top five positions. China’s Tsinghua University topped the pile for the fourth consecutive year, for added kudos. In the most competitive Emerging Economies Universities Rankings so far, it is a testament to the success of China’s investment in its higher education sector that it becomes the first country or region to achieve the top five positions in this ranking,” said Phil Baty, chief knowledge officer at the publication.
