Parasitic Birds Blend into Their Nests

Be they protists, worms, or vertebrates, parasites depend on their ability to deceive. The nest parasites, like the cowbird and cuckoo, mimic the offspring of their host birds. Their eggs often look like the eggs of a host bird (at least within the visual world of the host), and when they hatch they imitate theContinue reading “Parasitic Birds Blend into Their Nests”

Kudos to a Great Graphic Artist Rubin Bolling: Alternative MAUS Hits Home

-by Ptera Hunter Among the best responses that I have seen to date about the recent mashugana decision by the Tennessee School Board to ban a book about the holocaust (because a cartoon mouse shows a breast) comes from graphic artist Ruben Bolling (a.k.a., Tom the Dancing Bug.) One of Mr. Bolling’s most recent parodies,Continue reading “Kudos to a Great Graphic Artist Rubin Bolling: Alternative MAUS Hits Home”

Dinner and a Date with a Twist

Organisms lie, exaggerate, and scam their way to food, to territory and to sex. In one species of firefly, females can dine on the males of another species if they send a phony mating signal. The duped male becomes dinner rather than a date. Because of this threat, males will approach females with caution. SometimesContinue reading “Dinner and a Date with a Twist”

The Lying Fiddler

Everything lies. For virtually every species, lying and lie detection are essential survival skills. Fiddler crabs that have lost a claw will re-grow a bigger but weaker claw. When challenged by a smaller crab, the weak-clawed fiddler will bluff. It will display a fighting stance that tells the smaller crab that a confrontation would beContinue reading “The Lying Fiddler”

The Braggart Goldenrod

Golden Rod and Vespid wasps (Ptera Hunter, Salem IL, 2006). Yellow attracts many pollinating insects, including these vespid wasps.  Bees and wasps have trichromatic vision (three pigments), but they are not the same visual pigments (opsins) that we have. They can see farther into the ultraviolet but less well in the reds.  Their clue toContinue reading “The Braggart Goldenrod”

On Track for a Societal Collapse Soon

One of the things we look for in good science is the ability to make predictions. In 1972, an MIT team modeled twelve different possible scenarios for the future based upon different responses to the environment. Since then, we have followed the BAU2 (Business as Usual) scenario. Based upon our desire for continued economic growth,Continue reading “On Track for a Societal Collapse Soon”

An Intelligent Spider?

When we think about animal geniuses, arthropods don’t usually top the list of usual suspects. However, one genus of jumping spiders, Portia, includes spiders who have a gift: they can devise hunting strategies and make decisions. Portia makes their livings by hunting other spiders. These eight-legged geniuses do not simply attack; they appear to makeContinue reading “An Intelligent Spider?”
