New mapping methods developed by researchers at the Department of Energy’s Oak Ridge National Laboratory can help urban planners minimize the environmental impacts of cities’ water and energy demands on surrounding stream ecologies.

In an analysis published in Proceedings of the National Academy of Sciences, an ORNL-led team used high-resolution geospatial modeling to quantify the effects of land, energy, and water infrastructures on the nation’s rivers and streams. 

The vulnerability and conservation value of sub-tropical reefs south of the Great Barrier Reef - regarded as climate change refuges – has been highlighted in a new study.

Kodiak brown bears are abandoning salmon–their iconic prey–due to climate change, according to a new study.  

Canada’s current wetland protection efforts have overlooked how the environment naturally protects fresh-water resources from agricultural fertilizer contaminants, researchers from the University of Waterloo have found.

In a recent study, researchers at Waterloo’s Faculty of Science and Faculty of Engineering found that small wetlands have a more significant role to play than larger ones in preventing excess nutrients like nitrogen and phosphorus from fertilizer from reaching waterbodies such as the Great Lakes.

Non-toxic, lubricant-infused coatings deter mussels and prevent their attachment by disrupting their mechanosensory and adhesive systems.

Researchers have identified, for the first time, the likely origin of the cross-reactivity between cypress pollen, peaches and citrus fruits.

Climate change and habitat conversion to agriculture are working together to homogenize nature, indicates a study in the journal Global Change Biology led by the University of California, Davis.

In other words, the more things change, the more they are the same.

While the individual impacts of climate change and habitat conversion on wildlife are well-recognized, little is known about how species respond to both stressors at once.

New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published today in the journal Science Advances and led by the University of California, Davis.

These technologies can be applied to a wide range of species around the world — from mushrooms to walruses — but the study focuses on two iconic species of Pacific salmon: steelhead and chinook. While steelhead are a legendary sport fish, chinook are considered the workhorse of the West Coast salmon industry.

The coming decade may determine whether humanity will set a course toward a more socially and ecologically sustainable society. A crucial part of this goal is to develop a better understanding of how cooperation can be improved and become more effective, both within and among private stakeholders and public institutions.

“Collaborative governance is often highlighted as a solution to different environmental problems. For example, when small-scale fishermen agree to avoid overfishing or when states agree to reduce greenhouse gases. But we don’t know so much about how cooperation around environmental issues works in a complex world. Different actors want different things, different environmental problems are related to each other, and different groups have differing amounts of influence. Does cooperation actually lead to a better environment?” says Örjan Bodin, lecturer at the Stockholm Resilience Centre who conducts interdisciplinary research on better ways to handle diverse environmental problems.

Researchers have developed a method to evaluate atmospheric conditions using mosses (bryophytes) in urban areas, a development that could facilitate broader evaluations of atmospheric environments.

Many urban areas face atmospheric problems such as pollution and the heat island effect. With the need to evaluate atmospheric conditions, bioindicators—organisms whose response to environmental changes indicates the health of an ecosystem—have attracted considerable attention. Their merits include being able to evaluate an environment over a wide area at a low cost; detect environmental changes over an extended period; and assess these changes’ effects on the ecosystem. Bryophytes are one such group of plants known to be sensitive to environmental changes, in particular to atmospheric conditions.
