Just like with humans, the skin on marine mammals serves as an important line of defense against pathogens in their environment. A new study sheds light on the skin microbiome--a group of microorganisms that live on skin--in healthy humpback whales, which could aid in future efforts to monitor their health.
When simulating future environmental conditions researchers face a problem: laboratory experiments are easy to control and to reproduce, but are insufficient to mimic the complexity of natural ecosystems. In contrast, experiments under real conditions in nature are much more complicated and difficult to control. Scientist of the GEOMAR Helmholtz Centre for Ocean Research Kiel have combined both approaches to investigate the response of a major plankton species to increasing ocean acidification. The results have now been published in the international journal Nature Ecology and Evolution.
A study by Indiana University researchers shows that excess emissions -- which occur with plant shut-downs, start-ups and malfunctions, and not just in connection with natural disasters -- can make serious contributions to overall air pollution.
Over the last 125 years, and particularly after an uptick in industrial fishing since 1950, North Pacific seabirds -- typically fish consumers -- have shifted their prey preferences, a new study reports; they are eating lower on the food chain, consuming more squid.
The Paris Agreement has aspirational goals of limiting temperature rise that won't be met by current commitments. That difference could make the world another degree warmer and considerably more prone to extreme weather.
Overwhelming scientific evidence has demonstrated that our planet is getting warmer due to climate change, yet parts of the eastern US are actually getting cooler. According to a Dartmouth-led study in Geophysical Research Letters, the location of this anomaly, known as the 'US warming hole,' is a moving target. During the winter and spring, the US warming hole sits over the Southeast, as the polar vortex allows arctic air to plunge into the region, resulting in persistently cooler temperatures.
Scientists have discovered an extreme lack of genetic diversity and other threats to the future adaptability of domestic chickpeas, the primary source of protein of 20 percent of the world's people. But they also collected wild relatives of chickpeas in Turkey that hold great promise as a source of new genes for traits like drought-resistance, resistance to pod-boring beetles, and heat tolerance.
Scientists agree that changes in land use such as deforestation, not just emissions of greenhouse gases, can play a significant role altering the world's climate systems. Now, a new study by researchers at MIT and Dartmouth College reveals how another type of land use, intensive agriculture, can impact regional climate.
A lot of pro-environmental messages suggest that people will feel guilty if they don't make an effort to live more sustainably or takes steps to ameliorate climate change. But a recent study from Princeton University finds that highlighting the pride people will feel if they take such actions may be a better way to change environmental behaviors.
Scientists have for the first time captured the sounds of snapping shrimp off the Oregon coast and think the loud crackling from the snapping of their claws may serve as a dinner bell for eastern Pacific gray whales, according to new research being presented at the Ocean Sciences Meeting here today.
