- 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
- -07-04-10 Tree-Eating Beetles Invade Italy (Christian Science Monitor)
"In Sicily it has killed an estimated 13,000 palms and has pushed north, attacking trees in Campania and Rome, and all the way up to the famed Italian Riviera, near the border with France."
"Conservationists are calling the weevil infestation a national emergency and say there is, as of yet, no proven way of combating the insect. Scientists have found they can capture the bugs using traps laced with pheromones, but deploying the devices is time-consuming and costly." 07-10

- Biomimicry (Time.com - Amory B. Lovins)
"[Janine] Benyus draws her design inspiration from nature's wisdom, not people's cleverness. Some 3.8 billion years of evolution have exposed the design flaws of roughly 99% of nature's creations — all recalled by the Manufacturer. The 1% that have survived can teach powerful lessons about how things should be built if they're to last. For example, nature's design genius has led to the creation of bat-inspired ultrasonic canes for the blind, synthetic sheets that collect water from mist and fog as desert beetles do, and paint that self-cleans like a lotus leaf. Little plastic-film patches have been designed using adhesiveless gecko-foot technology, so that carpet tiles can be stored in a big roll, but also easily removed. Equally promising, we'll soon make solar cells like leaves, supertough ceramics that resemble the inner shells of abalone, and underwater glue that mimics the natural as forests." 10-07
- Beware of Asian Longhorn Beetle (WTNH.com)
"If Connecticut's parks and forests had a most wanted list, the Asian Longhorned Beetle would be at the top, and politicians and scientists want you to be on the lookout for this dangerous killer." 08-09
- A Jellyfish Explosion from Warming Oceans (CBS News)
"Hearing fishermen's pleas, Uye, who had been studying zooplankton, became obsessed with the little-studied Nomura's jellyfish, scientifically known as Nemopilema nomurai, which at its biggest looks like a giant mushroom trailing dozens of noodle-like tentacles."
"He concluded China's coastal waters offered a perfect breeding ground: Agricultural and sewage runoff are spurring plankton growth, and fish catches are declining. The waters of the Yellow Sea, meanwhile, have warmed as much as 1.7 degrees C (3 degrees F) over the past quarter-century."
"Scientists believe climate change - the warming of oceans - has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles and other pests to spread to new latitudes."
"The gelatinous seaborne creatures are blamed for decimating fishing industries in the Bering and Black Seas, forcing the shutdown of seaside power and desalination plants in Japan, the Middle East and Africa, and terrorizing beachgoers worldwide, the U.S. National Science Foundation says. " 11-09
- Younger Dryas Period (Wikpedia.org)
"The Younger Dryas saw a rapid return to glacial conditions in the higher latitudes of the Northern Hemisphere between 12.9–11.5 ka BP in sharp contrast to the warming of the preceding interstadial deglaciation. It has been believed that the transitions each occurred over a period of a decade or so, but the onset may have been faster. Thermally fractionated nitrogen and argon isotope data from Greenland ice core GISP2 indicate that the summit of Greenland was approximately 15 °C (27.0 °F) colder during the Younger Dryas than today. In the UK, coleopteran fossil evidence (from beetles) suggests that mean annual temperature dropped to approximately 5 °C (41 °F), and periglacial conditions prevailed in lowland areas, while icefields and glaciers formed in upland areas. Nothing of the size, extent, or rapidity of this period of abrupt climate change has been experienced since."
In everyday language, around 12,900 years ago a catastrophic event caused a rapid climate change. 08-11
