Offered the chance to be free by the avowed white supremacist P.W. Botha if he would renounce violence, Mandela replied, “Let him renounce violence.” Americans should understand this. Violent resistance to tyranny, violent defense of one’s body, is not simply a political strategy in our country, it is taken as a basic human right. Our own revolution was purchased with the blood of 22,000 nascent American dead. Dissenters were tarred and feathered. American independence and American power has never rested on nonviolence, but on the willingness to do great—at times existential—violence.
Cuttlefish remember What, When, and Where They Ate
by Ed Yong
Like octopuses and squid, cuttlefish are cephalopods—a group of animals known for their amazing colour-changing skin and sophisticated intelligence. Cuttlefish are separated from birds and mammals by almost a billion years of evolution. But Jozet-Alves, together with Clayton and Marion Bertin, has shown that they too can “keep track of what they have eaten, and where and how long ago they ate”.
They are also soft-bodied and nutritious, which puts them on the menu of virtually every major group of ocean predator. Cuttlefish deal with these manifold threats through camouflage, defensive ink, and just plain-old hiding. They spend more than 95 percent of their time hiding in safe places. When they do venture out to search for food, it pays them to be quick about it. “Cuttlefish live fast and die young. They live less than two years, but their size drastically increases between hatching and old age,” says Jozet-Alves. “They definitely need to be very efficient when foraging if they want to grow as fast as possible.”…
Study shows male chameleons fighting prowess tied to color changing abilities
(Phys.org) —Two researchers from Arizona State University have found that male chameleons use their color changing abilities for far more than hiding from predators. In their paper published in the journal Royal Society Biology Letters, Russell Ligon and Kevin McGraw describe a study they conducted with captive chameleons that showed that male veiled chameleons use their colors to intimidate other males and that head coloring can predict who might win in a scuffle…
How to keep your venus fly trap happy (and alive) - by flora-file
After my post about cutting the flower buds off when a venus fly trap flowers, I got some questions about how to care for this plant, and specifically people asked how I could possibly keep one alive for ten years. Just follow these handy dandy tips to keep your venus fly trap chomping small invertebrates for years to come.
Sunlight - Unfortunately this plant is not a houseplant. It needs direct sun to survive, hopefully about 8 hours a day. Mine lives on my patio and gets a few hours of direct light in the morning, and then bright indirect light (which is different than shade) for the rest of the day, and it seems to do fine. Plants that don’t get enough light tend to have elongated leaves, stretched out by the plants hopeless attempt to grow toward some source of light. Happy plants have short leaves and lots of traps. They still need light to photosynthesize no matter how many flies or spiders you feed them.
Distilled or Purified Water - These plants are very sensitive to minerals dissolved in water, especially the fluoride and chloride found in most tap water. Not even spring water is okay, as it contains trace minerals that may be detrimental to the health of the plant. Rainwater will probably work, as long as you don’t live next to a coal burning power plant or some other source of gross air pollution. This may be the most common form of venus fly trap neglect, as people that have killed their fly trap have usually not followed this important rule.
Peat Moss or Coco Coir substrate - The venus fly trap is a bog plant that naturally grows in mucky, nitrogen deprived soil. The whole bug eating behavior arose from the need for additional nitrogen that was severely lacking in the soil. Both peat moss and coco coir have extremely low nitrogen content, making them suitable for the needs of this plant. I used coco coir when I repotted mine a couple years ago, and it worked great. Coco coir is much cheaper than peat moss, and also a better choice environmentally.
A steady diet of…nothing! - Don’t give it fertilizers or chemicals, no Dr Shultz or Miracle Grow. And don’t feed it hamburger either, that’s just wrong. If it is healthy it will catch bugs all by itself, almost like its evolved to catch bugs or something. Keep the substrate constantly moist. I keep mine in a container that doesn’t drain and keep it in standing water constantly. Whatever happens, don’t let it dry out.
If you follow these simple steps your fly trap should grow old of the bulb and long in the tooth. I’m not saying this is the only way to take care of your fly trap, but its how I take care of mine. And after 10 years its still working. Good luck, and garden on!
Not much is known about this mysterious species, measuring 50 cm long and has a powerful sting that can be felt in the water surrounding the creature.
The incredibly rare Crambione cookiihad not been seen since 1910, but has recently been discovered on the coast of Queensland, Australia, where he was captured.
His sketch has so far been the only record of the living creature and has even been used to help identify the animal by jellyfish expert Lisa-Ann Gershwin, who confirmed the existence of this unusual marine inhabitant after he was captured.
A friend of yours told me you’re the one to ask if you have a bug you’ld like to have identified. A friend of mine saw this in South Africa and no one we know seems to have a clue what it is. Hopefully you can help us.
Thank you! Veerle
This is a longhorn beetle (family Cerambycidae). As best I can tell, it seems to be Lasiopeezus nigromaculatus. Unfortunately, I am unable to find any other information on this creature for you.
This genus contains a number of red-and-green or blue-striped species of leafhopper. These small insects typically measure around 1/4 to 1/2 an inch (1/2 to 1 cm), but their brilliant colors can be quite eye-catching.
This one, the Red-banded (or sometimes Candy-striped) Leafhopper, G. coccinea, ranges from Canada to Panama and can be found in habitats from meadow to forest. Relatively common, it can be encountered from spring through fall in the north, and year-round in warmer parts of its range, such as the gulf states.
Leafhoppers feed on plant sap, piercing the stem of herbaceous plants with their tube-like proboscis. As their common name implies, they are excellent jumpers, leaping dozens of body-lengths using their long, modified hind legs. The bristles on the hind legs are used to spread a secretion across their body that acts as a waterproofing and carries pheromones.
A Scientist’s Search for the Elusive Lizard in Texas
Cross an elusive lizard, a determined zoologist and a historic Air Force base and what do you get?
Several years ago, Nature Conservancy vertebrate zoologist Mike Duran was concerned. In his seven years of conservation work, he’d never once seen a spot-tailed earless lizard (Holbrookia lacerata).
The northern subspecies, or H.l.lacerata, historically occurs above the Balcones Escarpment, the fault line that separates the Edwards Plateau from the Tamaulipan Thornscrub ecoregion of southern Texas. The southern subspecies, or H.l.subcaudalis, has dwelled traditionally below that fault line. But in modern times, finding either type of the lizard—which measures four-and-a-half to six inches long and has no external ear openings—has proven difficult, if not impossible…
The albatross Wisdom, at almost 63 the world’s oldest, banded wild bird, laid another egg in late November, a year and a day after her last one. She’s at Midway Atoll Refuge, nesting site for 71 percent of the world’s population of Laysan albatross.
The Pacific leaping blenny(Alticus arnoldorum) is a fish out of water. The legless land fish makes its home on the intertidal rocks on the island of Guam (map), and new research shows how this strange fish was able to make the leap from stealthy swimmer to landlubber.
The two- to three-inch (4 - 8 cm) blenny does everything on land, from finding its steady diet of algae and detritus to mating and nesting. Its love of dry land is perhaps best reflected in how it escapes from threats like predators or researchers trying to trap it…
