Coral reefs struggle to keep up with rising seas, leave coastal communities at risk

Thu, 20 Apr 2017 09:37:17 EDT ~ In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai'i, researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion. Find out more...

Prescribed forest fire frequency should be based on land management goals

Tue, 18 Apr 2017 12:08:20 EDT ~ Researchers have studied forests subjected to different frequencies of fires to determine what effects fire can have on oak forests over long periods of time. They found that the frequency of prescribed forest fires should be determined based on the long-term goals of land managers. Find out more...

Tracking down water pollution through DNA of algae

Tue, 18 Apr 2017 11:43:44 EDT ~ The degree of pollution of rivers resulting from human activities is assessed using different biotic indices. The latter reflect the ecological status of a river based on the quantity and diversity of organisms selected as bioindicators, due to their ecological preferences and tolerance to pollution. This is the case of diatoms, algae consisting of a single cell surrounded by a silica skeleton, recommended by researchers as one of the ideal bioindicators for rivers and lakes. Find out more...

Evaluating cultural value of landscapes using geotagged photos

Wed, 12 Apr 2017 09:12:20 EDT ~ A new method has been devised for assessing the cultural value of landscapes using geotagged photos shared on a social-networking service. Data obtained with this method could help determine which locations should be used for tourism or targeted for environmental protection. Find out more...

Eat wild venison to support native woodland birds, says ecologist

Mon, 10 Apr 2017 19:41:41 EDT ~ Wild deer in Britain should be hunted for venison to drastically reduce their populations and support the re-emergence of our native woodland birds, according to an academic. Find out more...

North America's freshwater lakes are getting saltier

Mon, 10 Apr 2017 12:40:31 EDT ~ North America's freshwater lakes are getting saltier due to development and exposure to road salt. A study of 371 lakes reports that many Midwestern and Northeastern lakes are experiencing increasing chloride trends, with some 44 percent of lakes sampled in these regions undergoing long-term salinization. The study is the first large-scale analysis of chloride trends in freshwater lakes. Find out more...

Large, high-intensity forest fires will increase

Mon, 10 Apr 2017 08:55:10 EDT ~ Wildfire experts predict that by 2041, there will be four large, high-intensity forest fires for every three that occur now, with the number of days when conditions are conducive to fires increasing. Find out more...

Logging threatens breeding turtles

Mon, 10 Apr 2017 08:50:16 EDT ~ Debris from logging in tropical forests is threatening the survival of hatchling leatherback turtles and the success of mothers at one of the world's most important nesting sites in Colombia, report investigators. Find out more...

Tropical lowland frogs at greater risk from climate warming than high-elevation species, study shows

Fri, 07 Apr 2017 10:35:46 EDT ~ A new study of Peruvian frogs living at a wide variety of elevations -- from the Amazon floodplain to high Andes peaks -- lends support to the idea that lowland amphibians are at higher risk from future climate warming. Find out more...

Putting a price tag on biodiversity

Thu, 06 Apr 2017 15:16:51 EDT ~ A team of economists and ecologists has developed one of the first models to assign a dollar value to the loss or gain of species in an ecosystem. This new work offers an economic argument for preserving biodiversity. Find out more...
