Here are some highlights from the latest ESA Policy News by Science Policy Analyst Terence Houston. Read the full Policy News here. HOUSE: FY 2013 BUDGET PROPOSAL CUTS INNOVATION, FEDERAL WORKFORCE On March 20, House Republicans unveiled their proposed budget resolution for Fiscal Year (FY) 2013. Sponsored by House Budget Committee Chairman Paul Ryan (R-WI), the budget bill sets an overall discretionary spending limit of $1.028 trillion in FY 2013, $19 billion below the spending caps established in the Budget Control Act. Among its provisions, the House budget resolution includes significant cuts to Department of Energy programs while expanding oil and gas drilling. It also supports the sale of 3.3 million acres of federal lands identified in a 1997 Department of Interior report that were deemed suitable for sale or exchange to benefit the Everglades restoration effort in Florida. The White House released a statement asserting that the Ryan plan would cut clean energy programs by 19 percent and slash $100 billion from science, space and technology programs over the next decade. The budget also proposes to cut the federal government workforce by 10 percent, providing $368 billion in savings. Under the proposal, federal employee retirement contributions would also rise from 0.8 percent to 6.3 percent. The bill would also extend the current federal pay freeze to 2015.

SENATE: COMMITTEE REVIEWS EPA MERCURY STANDARDS FOR POWER PLANTS On March 20, the Senate Environment and Public Works Subcommittee on Clean Air and Nuclear Safety met for a hearing on the Environmental Protection Agency’s new mercury rules for power plants. EPA finalized the Mercury and Air Toxics Standards (MATS), the first national standards to protect American families from power plant emissions of mercury and other toxic air pollution like arsenic, acid gas, nickel, selenium, and cyanide on Dec. 16, 2011. “I believe it’s possible to have a clean environment and a strong economy. I think it’s a false choice to say that we have to have one or the other; we can have both. That is especially true for cleaning up our air pollution,” declared Clean Air and Nuclear Safety Subcommittee Chairman Tom Carper (D-DE) in his opening statement. “In fact, as the EPA has implemented the Clean Air Act Amendments of 1990, our nation’s air has gotten cleaner, while electricity rates have stayed constant and our economy has grown by 60 percent. For every dollar we spend cleaning the air, we’ve seen $30 returned in reduced health care costs, better workplace productivity, and lives saved.” Subcommittee Ranking Member James...
This post contributed by Monica Kanojia, Administrative Assistant/Governance for ESA. Amphibians have been around for hundreds of millions of years. They have survived numerous extinction events and yet somehow, in the past two decades, their numbers have been in severe decline. The population changes have been linked to many factors, including climate change and disease, habitat destruction and water pollution. Studies indicate that amphibians are sensitive to all of the proposed variables—not just one root cause. A unique quality of amphibian biology is their transdermal water uptake ability. Transdermal uptake allows for nutrients to be delivered across the skin. For example, the skin of a frog allows for the direct exchange of oxygen, carbon dioxide and water from the environment. While in ideal situations this would be beneficial, it currently poses a threat to amphibian populations. Overexposure to any nutrient can be lethal to an organism. With increased rates of carbon dioxide in the atmosphere, heavily polluted water and loss of water, amphibians’ ability to survive is diminishing. A majority of amphibian species go through reproductive and developmental stages that require a body of water. The eggs of amphibians are not as resilient as reptile or bird eggs because they are jelly coated and unsuitable for development on land; therefore, amphibians must return to water to reproduce. Increased agricultural and industrial run off and poor waste management has led to a decline in the quality of water available for amphibians. The main types of chemical contaminants affecting amphibian environments are pesticides and herbicides, heavy metals, increasingly acidic water and nitrogen pollution. According to a study published in the journal Environmental Health Perspectives by Tyrone Hayes from the University of California, Berkeley and colleagues, pesticides commonly used in cornfields in the western United States have adverse affects on amphibian larval growth and development, immune system and the size prior to and after metamorphosis. High levels of pesticides enter streams and groundwater as water runs off of farms, ranches, golf courses and suburban areas. While organic and low-risk pesticide use is encouraged by the U.S. Environmental Protection Agency, it remains predominantly unregulated… That is, the EPA lists guidelines for how to safely use pesticides for commercial and agricultural needs, but it does not strictly regulate what can and cannot be used. Herbicides, on the other hand, are made to disrupt photosynthesis capabilities of plants and were thought to have little to no effect on fish and wildlife. But, as Science Daily reported in 2008, studies have revealed otherwise. For example, atrazine—one of the most commonly used herbicides on golf courses, home lawns and soybean and corn crops—is responsible for lethal changes...
Frog legs are a culinary tradition in many cultures—featured in French and Cantonese cuisine, among others—and have been showing up in American cuisine as well, often as a culinary curiosity. In a recent article in the Washington Post, for example, frog legs were presented as a delicacy that could become more popular with American consumers if presented in a new way.
urrently, research on the possible causes of limb deformities in amphibians is expansive, with evidence supporting parasite infection, chemical contaminants, UVB radiation and amputation as possible factors. However, as Mari Reeves from the U.S. Fish and Wildlife Service and colleagues explained in an article in the August issue of Ecological Monographs, the most likely cause of amphibian abnormalities is a combination of several stressors.

From the Community: Pika population sees a boost, birds not spreading West Nile and five women honored for their role as environmentalists
Pika found to be flourishing in the Sierra Nevada region, bird migration patterns suggest mosquitoes are to blame for spreading West Nile and mice courtship rituals could shed light on autism. Here are news stories and studies on ecological science from the first week in March.
