Want the world to know what you’ve done?

The application deadline is now January, 15 2012.

Have you been working to preserve the world around you? Have you been teaching others how to protect the environment? Have you been doing an environmental research project? If your answer to any of these questions is yes, then you are a Young Eco-Hero. All Eco-Heroes serve as role models, showing others that each individual is important and can make a difference.

Action For Nature is proud to honor the work of young people between the ages of 8 and 16 who have done creative environmental projects. The winners of AFN’s International Young Eco-Hero Awards program receive a cash prize and a special certificate, as well as public recognition on our Web site and elsewhere.

Our judges are experts in environmental science, biology and environmental health. They select our Young Eco-Heroes from applicants from around the world. They are looking for young people to follow in their footsteps.

We are proud of all of our winners, and of all the applicants from around the world.

This is a great chance for you to share your environmental activism and creative work. We look forward to again supporting young people from all around the world working to save our planet. Please read the guidelines to see if you are eligible to apply to become a Young Eco-Hero. If you or someone you know is eligible fill out the 2012 Eco-Hero Awards Application.

Webinar: 2012 grant opportunities through Sustain Our Great Lakes

Please join us for a webinar on January 11, 2012 to learn about the 2012 grant funding opportunities to be offered through Sustain Our Great Lakes

On January 3, 2012, Sustain Our Great Lakes will invite applications for competitive funding through its Stewardship Grants Program and its Community Grants Program.  The Requests for Proposals will be available on January 3 at www.sustainourgreatlakes.org.  Funding priority for both programs will be given to on-the-ground restoration projects that improve the quality and connectivity of stream, wetland and coastal habitats in the Great Lakes basin.  Pre-proposals will be due on February 15, 2012.  

Webinar participants will learn about funding priorities and the application process, see examples of past projects, receive tips for submitting competitive proposals, and have the opportunity to ask questions.  The webinar will begin at 11 AM Eastern Time/10 AM Central Time and last for approximately 1 hour.

Webinar participants can register at: https://www1.gotomeeting.com/register/544871304

Please contact Todd Hogrefe, National Fish & Wildlife Foundation, at 612-564-7286 or todd.hogrefe@nfwf.org for more information.

Battery runs on paper, releases water as byproduct

Read the full story at Smart Planet.

Our batteries are full of toxic chemicals and then pollute our environment when we trash them. Clearly, they can be improved.

That’s why a new battery demonstrated by Sony at the Eco-Products conference in Tokyo is so exciting: It runs on shredded paper or cardboard and it’s only “waste” product is water.

Coca-Cola taps biotech firms to scale PlantBottle production

Read the full story at SmartPlanet.

Beverage giant The Coca-Cola Co. has tapped three biotechnology companies to aid with the commercialization of its plant-based packaging, PlantBottle.

The deals with Virent, Gevo and Avantium were made after Coca-Cola studied the approaches of more than 30 different potential partners, said Rick Frazier, vice president of commercial product supply, Coca-Cola. The new multi-million-dollar relationships center on exploiting the full potential of PlantBottle, a packaging approach that currently replaces up to 30 percent of the PET in bottles with plant-based materials. The goal is to extend PlantBottle so that 100 percent of the materials are plant-based, Frazier said.

A New Genre of Tires: Call ‘em “Sweet” and “Green”

Read the full story from the American Chemical Society.

Motorists may be driving on the world’s first “green” tires within the next few years, as partnerships between tire companies and biotechnology firms make it possible to produce key raw materials for tires from sugar rather than petroleum or rubber trees. Those new bio-based tires — already available as prototypes— are the topic of an article in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

Nitrogen from Humans Pollutes Remote Lakes for More than a Century

Read the full story from the University of Washington.

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm.

Wolfe (2011). ” A Coherent Signature of Anthropogenic Nitrogen Deposition to Remote Watersheds of the Northern Hemisphere.” Science 334(6062), 1545-1548. DOI: 10.1126/science.1212267.

Abstract: Humans have more than doubled the amount of reactive nitrogen (Nr) added to the biosphere, yet most of what is known about its accumulation and ecological effects is derived from studies of heavily populated regions. Nitrogen (N) stable isotope ratios (15N:14N) in dated sediments from 25 remote Northern Hemisphere lakes show a coherent signal of an isotopically distinct source of N to ecosystems beginning in 1895 ± 10 years (±1 standard deviation). Initial shifts in N isotope composition recorded in lake sediments coincide with anthropogenic CO2 emissions but accelerate with widespread industrial Nr production during the past half century. Although current atmospheric Nr deposition rates in remote regions are relatively low, anthropogenic N has probably influenced watershed N budgets across the Northern Hemisphere for over a century.

Acid Rain Poses a Previously Unrecognized Threat to Great Lakes Sugar Maples

Read the full story from the University of Michigan.

The number of sugar maples in Upper Great Lakes forests is likely to decline in coming decades, according to University of Michigan ecologists and their colleagues, due to a previously unrecognized threat from a familiar enemy: acid rain.

Abstract:

1. During the next century, atmospheric nitrogen (N) deposition is projected to more than double, potentially leading to a decline in plant diversity as well as a change in plant community composition and structure.

2.  In a decade-long field experiment, simulated atmospheric N deposition has slowed litter decay, resulting in an accumulation of forest floor (i.e. Oi & Oe horizons). We reasoned that a greater forest floor mass under simulated N deposition would impose a physical barrier to sugar maple Acer saccharum seedling establishment, thereby reducing seedling populations of an ecologically and economically important tree species.

3.  To test this idea, we first quantified sugar maple seedling abundance in replicate northern hardwood forest stands receiving ambient atmospheric N (7–12 kg N ha−1 year−1) and experimental atmospheric N deposition, simulating future amounts in eastern North America (ambient plus 30 kg NO3 N ha−1 year−1). Then, we experimentally manipulated forest floor mass under ambient and simulated N deposition treatments. Finally, we transplanted first-year established seedlings into areas receiving ambient and simulated N deposition and quantified their mortality after 1 year.

4.  First-year seedling abundance did not differ under ambient and simulated N deposition; however, there were greater abundances of second- and third-to-fifth-year seedlings under ambient N deposition (P < 0·001). In all cases, experimental manipulation to increase forest floor mass, equivalent to that under simulated N deposition, resulted in significantly (= 0·001) fewer established individuals, regardless of whether the greater forest floor mass occurred under ambient or simulated N deposition. Finally, fewer 1-year-old transplanted seedlings survived when grown under simulated N, albeit that result was not statistically significant.

5.Synthesis and applications. The slowing of decay and the accumulation of forest floor under anthropogenic N deposition can negatively impact seedling survival and potentially alter stand development and structural diversity. As atmospheric N deposition increases globally, it becomes necessary to understand the mechanisms that lead to population changes for ecologically important tree species. The responses we document should be considered in simulations of future of forest’dynamics, as atmospheric N deposition continues to increase, specifically when sugar maple life-history traits are included to simulate regeneration, structural diversity and stand development.
