- -Editorial: How to Save Biodiversity in the Face of Global Warming (International Herald Tribune)
"So as we start thinking seriously about how to stop messing it up any further, let's also start thinking about how to help all life forms adapt."
"I would propose three strategies to minimize the impact of climate change on biodiversity." 02-07

- Beetles, Tiger (Wikipedia.org)
"The fast-moving adults run down their prey. Some tiger beetles can run at a speed of 5 mph. For its size it has been suggested that they are the fastest running land animals. Some tiger beetles in the tropics are arboreal, but most run on the surface of the ground. They live along sea and lake shores, on sand dunes, around playa lakebeds and on clay banks or woodland paths."
"Tiger beetles have been considered as good indicator species and have been used in ecological studies on biodiversity." 06-06
- Sustainable Development (Wikipedia.org)
"Sustainable Development is an umbrella that attempts to bridge the divide between economic growth and environmental protection, while taking into account other issues traditionally associated with development. It seeks to develop means of supporting economic growth while supporting biodiversity, relieving poverty and without using up natural capital in the short term at the expense of long term development. While many definitions of the term have been introduced over the years, the most commonly cited definition comes from the report Our Common Future, more commonly known as the Brundtland Report, which states that sustainable development is development that 'meets the needs of the present without compromising the ability of future generations to meet their own needs'." 11-06
- Editorial: It's Too Late for "Later" (New York Times)
"There was a chilling essay in The Jakarta Post last week by Andrio Adiwibowo, a lecturer in environmental management at the University of Indonesia. It was about how a smart plan to protect the mangrove forests around coastal Jakarta was never carried out, leading to widespread tidal flooding last month."
"This line jumped out at me: 'The plan was not implemented. Instead of providing a buffer zone, development encroached into the core zone, which was covered over by concrete.' "
"You could read that story in a hundred different developing countries today. But the fact that you read it here is one of the most important reasons that later has become extinct. Indonesia is second only to Brazil in terrestrial biodiversity and is No. 1 in the world in marine biodiversity. Just one and a half acres in Borneo contains more different tree species than all of North America — not to mention animals that don’t exist anywhere else on earth. If we lose them, there will be no later for some of the rarest plants and animals on the planet."
"Indonesia is now losing tropical forests the size of Maryland every year, and the carbon released by the cutting and clearing — much of it from illegal logging — has made Indonesia the third largest source of greenhouse gas emissions in the world, after the United States and China. Deforestation actually accounts for more greenhouse gas emissions than all the cars and trucks in the world, an issue the Bali conference finally addressed." 12-07
- Bioenergy (Wiley.com)
"GCB Bioenergy exists to promote understanding of the interface between biological sciences and the production of fuels directly from plants, algae and waste. All aspects of current and potential biofuel production, from forestry, crop production, enzymatic deconstruction and microbial fuel synthesis to implications for biodiversity, ecosystem services, economics, policy and global change will be included." 01-09
- Perennial Grasses More Efficient Than Corn or Soybean (Mongabay.com)
"Biofuels derived from low-input high-diversity (LIHD) mixtures of native grassland perennials can provide more usable energy, greater greenhouse gas reductions, and less agrichemical pollution per hectare than can corn grain ethanol or soybean biodiesel. High-diversity grasslands had increasingly higher bioenergy yields that were 238% greater than monoculture yields after a decade. LIHD biofuels are carbon negative because net ecosystem carbon dioxide sequestration (4.4 megagram hectare–1 year–1 of carbon dioxide in soil and roots) exceeds fossil carbon dioxide release during biofuel production (0.32 megagram hectare–1 year–1). Moreover, LIHD biofuels can be produced on agriculturally degraded lands and thus need to neither displace food production nor cause loss of biodiversity via habitat destruction." 02-09
- Biochar for Soil Improvment and Long-Term Carbon Sequestration (Biochar.org)
"Biochar offers a strong link between the three Rio conventions as it simultaneously addresses climate change, soil degradation and biodiversity." 05-09
- Are We Destroying the Oceans? (Time.com)
"But human-related injury to the oceans is rife. We have fished out an estimated 90% of the major commercial fish species that swim the high seas, including the giant and endangered blue fin tuna. The trawlers carrying out that destruction are raking the ocean floor, turning parts of the once vibrant continental shelf into so much mud. Climate change is warming the oceans, disrupting the fundamental structure of the marine food pyramid and destroying coral reefs. Meanwhile, increased concentrations of CO2 in the atmosphere are making the seas acidic, which threatens to kill off species in large numbers. 'The ocean is becoming a desert,' says Jeremy Jackson, the director of the Center for Marine Biodiversity and Conservation at the Scripps Institution of Oceanography."
"Pollution that has washed off the land — from sewage that contains chemical toxins to nitrate fertilizer from farmland — has infected the oceans, destroying once vibrant coastal waters. But it's a problem we barely notice, since for many of us the oceans are distant and out of sight." 04-10
- Largest Survey of Ocean Life Is Completed (Wall Street Journal)
"The census is part of a wider push by scientists to create free, online digital libraries of biological data about life on earth. The marine data, for example, will feed into the Encyclopedia of Life project, an effort to document all 1.8 million named species on earth. There's also an International Barcode of Life project assembling DNA barcodes for all multi-cellular organisms."
"Scientists intend to use such digital libraries to study biodiversity on a planet-wide level, just as different types of meteorological data are pooled and used to predict weather. Spurring the efforts is a new field known as biodiversity informatics, which uses sophisticated computer techniques to sift and analyze data in novel ways."
"Since it began, data from the marine census has yielded some 2,700 scientific papers. One significant study published July, in the journal Nature, found a strong link between rising sea temperatures and the decline of marine algae, the basis of the oceans' food chain. Another census-based study in Nature found that warmer seas can hurt marine diversity, potentially rearranging the global distribution of ocean life." 10-10
- -11-25-11 Past Mass Extinctions of Life on Earth (Time.com)
"The end-Permian mass extinction, which their study calls the 'most severe biodiversity crisis in earth history,' wiped out 95% of marine life and 70% of life on land about 252.28 million years ago."
"The scientists are putting the blame on familiar culprits: carbon dioxide and methane." 11-11
- Cyanobacteria (Wikipedia.org)
"Cyanobacteria...also known as blue-green algae, blue-green bacteria, and Cyanophyta) is a phylum of bacteria that obtain their energy through photosynthesis."
"The ability of cyanobacteria to perform oxygenic photosynthesis is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity and leading to the near-extinction of oxygen-intolerant organisms. According to endosymbiotic theory, chloroplasts in plants and eukaryotic algae have evolved from cyanobacterial ancestors via endosymbiosis." 03-12
- Jellyfish May Survive Better Than Other Ocean Creatures (Time.com)
"Overfishing, climate change and pollution are also setting the stage for the rise of the jellyfish. It could almost be a case of evolution running backwards—complex, vertebrate biodiversity replaced by a monoculture of squishy things, thanks chiefly to us."
