Measuring marine biodiversity with "environmental DNA"—an application of gene sequencing to environmental biology—should permit rapid assessment of changes in marine life. That makes environmental DNA (eDNA) a critical tool for managing our response to climate change. But eDNA only works well if key implementation steps are followed, according to a new study of the Los Angeles and Long Beach area published in the journal PeerJ.
There's a popular saying that people who ignore history are doomed to repeat it. It turns out that there's another reason not to ignore history, according to new research from Michigan State University published in the journal Ecology.
A paper published in Environmental Pollution, authored by Saint Louis University (SLU) scientists, shows that human proximity is the best indicator of microplastics being found in the Meramec River in Missouri.
Over 300 million people in Sub-Saharan Africa (SSA) depend on maize for nearly 30% of their caloric intake, and the popularity of maize is expected to continue its upward trend (IITA). As the demand for maize increases, so does the need for sustainable and safe production, yet numerous biotic and abiotic stressors threaten this staple crop in SSA.
Changing weather patterns have profound impacts on agricultural production around the world. Higher temperatures, severe drought, and other weather events may decrease output in some regions, but effects are often volatile and unpredictable. Yet many countries rely on agricultural and food trade to help alleviate the consequences of local, weather-induced production shifts, a new paper from the University of Illinois suggests. The work is published in Global Food Security.
An estimated 80 percent of the world's cargo is transported via ship-borne containers—a method that has soared in use in the decades after World War II. The efficient, cost-effective method of packaging and moving goods across the world's oceans boomed with the globalization of trade, experiencing a near 20-fold increase in container tonnage in the past 40 years. An estimated 100 million tons were shipped by container in 1980. In 2020, that number reached a staggering 1.85 billion tons.
