Fishing the Gulf of Maine: Tradition at a Crossroads
May 20, 2013 11:41 AM - Michael Sanders, The Ecologist
Lobster fishing remains big business off the coast of Maine but even with new regulations and new gadgets can it ever be sustainable? Michael Sanders investigates the real costs of the crustacean on your plate... When most of us go down to the coast, whether to walk or swim or fish or sail, we take for granted what we see before us. We see the lobster boats and the colorful buoys marking the strings of traps, the bobbing green and red cans marking safe passage, the gulls and other seabirds. In the larger working harbors like Portland and Stonington and Port Clyde, there might be draggers tied up, unloading fish they've caught far out in the Gulf of Maine and on Georges Bank. What we don't realize is that this seemingly unchanging marine world is in fact always changing in ways both large and small. What we think of as "the coast of Maine" - those 3,000 vaunted miles of rocky shoreline punctuated by seaside villages and docks and lobster pounds and fishing fleets - was largely built on the backs of the fishermen and lobstermen who are there, however picturesque or authentic to the eye, for a single purpose: to harvest the sea in order to feed us.
Want to benefit wildlife? Let land go untended.
May 20, 2013 06:02 AM - Roger Greenway, ENN
Which environment would wildlife prefer, actively farmed and managed land, or untended natural land that to us might appear unkempt? Turns out that parts of the farm landscape that look overgrown and 'scruffy' are more important in supporting wildlife than they first appear, according to new research published today in Ecology Letters. The findings stem from an intensive study of an organic farm in Somerset by a team of scientists focussing on the complex ways in which animals and plants interact. First, the team of researchers from the University of Hull, the University of Bristol and the Centre for Ecology & Hydrology, created one of the world's largest terrestrial food-webs — a what-eats-what guide to the food-chain, and then developed a method of predicting what would happen to the whole food-web when habitats were lost.
Drought and Desertification - Global Response
May 19, 2013 09:11 AM - ANDREW BURGER, Global Warming is Real
Land degradation — more specifically drought and desertification — have become increasingly pressing problems for a growing number of countries around the world, threatening efforts to alleviate poverty, improve basic health and sanitation and address socioeconomic inequality, as well as spur agricultural and sustainable economic development. The only multilateral, international agreement linking development and environment to sustainable land management (SLM), high-level representatives from 195 nations will be gathering in Windhoek, Namibia from September 16-27 for the 11th bi-annual Conference of Parties (COP) to review implementation of the United Nations Convention to Combat Desertification (UNCCD). Meeting for the first time in southern Africa, UNCCD delegates will review implementation of the convention to date and plan for the ensuing two years of programs and actions.
Effects of a Warming Planet on Tropical Lizards May Not be Significant
May 18, 2013 07:50 AM - Dartmouth University via ScienceDaily
A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet. Most predictions that tropical cold-blooded animals, especially forest lizards, will be hard hit by climate change are based on global-scale measurements of environmental temperatures, which miss much of the fine-scale variation in temperature that individual animals experience on the ground, said the article's lead author, Michael Logan, a Ph.D. student in ecology and evolutionary biology.
DiCaprio's Environmental Charity Art Auction Raise $33 Million
May 17, 2013 07:37 AM - Editor, Justmeans
Leonardo DiCaprio's environmental charity auction at Christie's in New York has raised an impressive $33.3 million from wealthy art collectors. Most of the sale proceeds went to environmental protection causes promoted by the Leonardo DiCaprio Foundation. The Hollywood actor, who was himself present at the auction, urged collectors to bid as if the planet's fate "depends on us" - and they responded to his call generously.
EarthTalk: Climate Change and Hawaii’s Coral Reefs
May 16, 2013 09:04 AM - EarthTalk, Global Warming is Real
Despite sweeping protections put in place near the end of George W. Bush's presidency for large swaths of marine ecosystems around the Hawaiian Islands, things are not looking good for Hawaii’s coral reefs. Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on the reefs and the marine life they support. Biologists are trying to remain optimistic that there is still time to turn things around, but new threats to Hawaii's corals are only aggravating the situation...
Study Shows Scientists Agree on Anthropogenic Climate Change
May 16, 2013 06:02 AM - ScienceDaily
A comprehensive analysis of peer-reviewed articles on the topic of global warming and climate change has revealed an overwhelming consensus among scientists that recent warming is human-caused. The study is the most comprehensive yet and identified 4000 summaries, otherwise known as abstracts, from papers published in the past 21 years that stated a position on the cause of recent global warming -- 97 per cent of these endorsed the consensus that we are seeing human-made, or anthropogenic, global warming (AGW) Led by John Cook at the University of Queensland, the study has been published 16 May, in IOP Publishing's journal Environmental Research Letters.
Mussels May Help Filter Polluted Waters
May 14, 2013 10:28 AM - Editor, ENN via YaleEnvironment360
Scientists from the U.S. National Oceanic and Atmospheric Administration (NOAA) set up an experimental raft at the mouth of New York City's Bronx River last spring. Hanging beneath it were long, sock-like tendrils that had been seeded with Geukensia demissa, commonly known as ribbed mussels. The point of the two-year experiment was to see whether mussels would survive or even thrive given the industrial and organic effluent that flows from the Bronx into the greater New York Harbor. If the mussels did in fact prosper in this environment, it could have implications for how we might help clean up coastal waters in various parts of the world.
Nature is Good for your Health!
May 14, 2013 06:31 AM - Richard J Dolesh, The Ecologist
A walk in the park can calm and restore you. This is something we take for granted in parks and recreation, because we have known it to be true ever since we started spending time in nature. But new research reported in the British Journal of Sports Medicine now provides scientific proof that walking in nature and spending time under leafy shade trees causes electrochemical changes in the brain that can lead people to enter a highly beneficial state of "effortless attention." The UK researchers state with some justifiable academic stuffiness that "..happiness, or the presence of positive emotional mindsets, broadens an individual's thought-action repertoire with positive benefits to physical and intellectual activities, and to social and psychological resources."
