The 2018 Environmental Performance Index (EPI) finds that air quality is the leading environmental threat to public health. Now in its twentieth year, the biennial report is produced by researchers at Yale and Columbia Universities in collaboration with the World Economic Forum. The tenth EPI report ranks 180 countries on 24 performance indicators across 10 issue categories covering environmental health and ecosystem vitality.
Policymakers are often concerned with the preservation of biodiversity at national, continental or global scales, but most biodiversity monitoring is conducted at very fine scales. This mismatch between the scales of our policies and of our data creates serious challenges, especially when assessing biodiversity change. In a new study, published in Ecological Monographs today, nearly the entire global research community addressing this problem was asked to put their techniques to the test by applying them to the same data set.
Research led by The University of Texas at Austin has found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites.
Male sea turtles are disappearing and not just in Australia. FAU researchers found that 97 to 100 percent of hatchlings in southeast Florida have been female since 2002. They are the first to show why and how moisture conditions inside the nest in addition to heat affect the development and sex ratios of turtle embryos, using a novel technique they developed to estimate sex ratios with a male-specific, transcriptional molecular marker Sox9.
A new study demonstrates how conservation practices championed by Maine lobstermen help make the lobster fishery resilient to climate change.
The Research Group of Biological Invasion and Adaptive Evolution (BIAE; PI: CHEN Yifeng) at Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences recently answered how reproductive phenology of Gymnocypris selincuoensis, an endemic fish in Lake Selicuo in Tibetan Plateau, associated with climate changes.
A new study from WCS (Wildlife Conservation Society) and partners reveals for the first time the ways in which wild weather swings and extreme icing events are negatively impacting the largest land mammal of the Earth's polar realms -- the muskoxen. The paper demonstrates that while this denizen of the Arctic and other cold-adapted species have spectacular adaptations, the previously unknown effects of rain-on-snow events, winter precipitation, and ice tidal surges are costly for the animals, if not deadly.
As co-author of a study published in Global Change Biology, Kenneth Feeley, along with fellow biologist, Richard Tito, a native Quechua Indian from the region and the study's first author, discovered that tough times lie ahead for rural farmers growing the Andes' staple crops -- corn and potatoes.
The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals.
2017 was the warmest year on record for the global ocean according to an updated ocean analysis from Institute of Atmospheric Physics/Chinese Academy of Science.
