Parrotfish play critical role in building coral reefs
April 28, 2015 01:42 PM - University of Exeter

As well as being a beautiful species capable of changing its colour, shape and even gender, new research published today shows that parrotfish, commonly found on healthy coral reefs, can also play a pivotal role in providing the sands necessary to build and maintain coral reef islands.

Climate warming leads to earlier tick season
April 28, 2015 08:46 AM - Cary Institute of Ecosystem Studies

The month of May brings many things, among them Mother’s Day, tulips, and Lyme Disease Awareness campaigns. But according to Dr. Richard S. Ostfeld, a disease ecologist at the Cary Institute of Ecosystem Studies in Millbrook, NY, if we want to get a leg up on tick-borne illness we need to become vigilant earlier in the season.

Why Bees Can't Avoid Pesticides
April 27, 2015 01:07 PM - Steve Williams, Care2

Pesticides such as as neonicotinoids are already under close scrutiny because research appears to show that, certainly for honey bees at least, they may interrupt the insect’s normal behaviors and they are suspected to play a part in colony collapse disorder.

What's worse for polar bears- Global Warming or Pollution?
April 24, 2015 02:44 PM - Tim Radford, The Ecologist

As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival.

Cross-species animal fights explained by new research
April 24, 2015 07:54 AM - UNIVERSITY OF CALIFORNIA - LOS ANGELES via EurekAlert

Why do animals fight with members of other species? A nine-year study by UCLA biologists says the reason often has to do with "obtaining priority access to females" in the area.

The scientists observed and analyzed the behavior of several species of Hetaerina damselflies, also known as rubyspot damselflies. For the study, published this month in the print edition of the journal Proceedings of the Royal Society B, researchers observed more than 100 damselflies a day in their natural habitat along rivers and streams in Texas, Arizona and Mexico.

What countries have the most endangered animals?
April 23, 2015 10:55 AM - Susan Bird, Care2

If you had to guess which countries are losing the greatest number of endangered mammals to extinction, which would you pick? Actually, you don’t have to guess. There’s a new map that will show you, in no uncertain terms, where in the world we’re losing animals the fastest. The top three “winners” of this unfortunate contest are Indonesia (184), Madagascar (114), Mexico (101), with India following close behind at 94.

Putting a value on our Oceans
April 23, 2015 06:56 AM - World Wildlife Fund, Justmeans

The ocean’s wealth rivals those of the world’s leading economies, but its resources are rapidly eroding, according to a new World Wildlife Fund (WWF) report. The analysis, Reviving the Ocean Economy: The Case for Action, conservatively estimates the value of key ocean assets to be at least $24 trillion. If compared to the world’s top 10 economies, the ocean would rank as the seventh largest, with an annual value of goods and services of $2.5 trillion.

The report, produced in association with The Global Change Institute at the University of Queensland and The Boston Consulting Group (BCG), combines scientific evidence of environmental degradation with an economic case for urgent conservation action. Using an innovative economic analysis, the ocean’s value is quantified based on assessments of goods and services ranging from fisheries to coastal storm protection, resulting in an overall asset value and an annual dividend output (comparable to a GDP).

A brief history of Earth Day
April 22, 2015 09:59 PM - Earth Day Network

Each year, Earth Day -- April 22 -- marks the anniversary of what many consider the birth of the modern environmental movement in 1970.

The height of hippie and flower-child culture in the United States, 1970 brought the death of Jimi Hendrix, the last Beatles album, and Simon & Garfunkel’s “Bridge Over Troubled Water”. Protest was the order of the day, but saving the planet was not the cause. War raged in Vietnam, and students nationwide increasingly opposed it.

 

Ants avoid traffic jams
April 22, 2015 09:37 AM - Springer via EurekAlert!

Rather than slowing down, ants speed up in response to a higher density of traffic on their trails, according to new research published in Springer's journal The Science of Nature - Naturwissenschaften. When the researchers increased the supply of food by leaving food next to the trail, ants accelerated their speed by 50 percent. This was despite more than double the density of traffic.

The Sage Grouse is NOT getting Endangered Species Act protection
April 22, 2015 07:23 AM - Center for Biological Diversity

The U.S. Fish and Wildlife Service today abandoned its plan to give Endangered Species Act protection to Mono Basin sage grouse, a small and isolated population of prairie birds in Nevada and California that remain under threat from grazing, habitat loss and mining development. The agency’s decision ignores scientific recommendations for reversing the birds’ steep decline and relies on unproven conservation agreements with state and local communities.

The Mono Basin greater sage grouse population, located in eastern California and western Nevada and also known as the “bi-state” population, is fragmented and geographically isolated from all other greater sage grouse populations.
