... Science Frontiers ONLINE No. 69: May-Jun 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Extinction Countdown Some plants may, as described below, have environment-sensitive genes that help them adjust to external pressures. Amphibians and birds do not seem to be so pliable. The worldwide precipitous decline of amphibian populations is alarming. Her-petologists are literally seeing species disappear before their eyes. Here is a typical anecdote: "In 1974, Michael Tyler of the University of Adelaide, Australia, described a newly discovered frog species that broods its young in its stomach. The frog was once so commo 'an agile collector could have picked up 100 in a single night,' Tyler says. By 1980 it had completely disappeared from its habitat (a 100-square-kilometer area in the Conondale Ranges, 100 miles north of Brisbane). It has not been seen since." Similar stories emanate from Brazil, Japan, Mexico, Norway, and elsewhere. Many environmental causes have been proposed, but it is significant that the frogs are also disappearing from nature preserves where environmental pressures are small. D. Wake, a biologist at Berkeley, has remarked: "[ Amphibians] were here when the dinosaurs were here, and [they] survived the age of mammals. If they're checking out now, I think it is significant." In this context, Wake believes that there is a single, global, still-unidentified cause operating. (Barinaga, Marcia; "Where Have All the ...

... Science Frontiers ONLINE No. 40: Jul-Aug 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Frog mothers do so care!We usually think of reptiles and amphibians as bad parents, leaving their eggs unguarded and their young to fend for themselves. The strawberry poison-dart frog of Panama and Columbia seems to be an exception. The parents stand guard over the eggs, moistening them until the tadpoles emerge. Then, the mother allows the tadpoles to wriggle onto her back and, one at a time, she carries them to separate little pools of water trapped in bromeliad fronds. She even goes one remarkable step further. Remembering the location of each tadpole, she makes the rounds, depositing infertile eggs for them to eat! (Anonymous; "Gallery," Discover, 6:55, May 1985.)

... Science Frontiers ONLINE No. 76: Jul-Aug 1991 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Flying, parachuting, and falling frogs (Top) Shapes of flying and non-flying frogs. (Bottom) Aerodynamic diagram for a flying frog. Falling frogs have always been a Fortean favorite. These particular frogs plummet to earth in uncontrolled, unchecked free fall after (presumably) being lofted by whirlwinds. But there are frogs that are aerodynamically more sophisticated; these creatures glide and parachute through the dense tropical forests. S.B . Emerson and M.A .R Koehl have inquired into (even resorting to models in wind tunnels) the morphological and behavioral changes that have accompanied the repeated evolutions of these airworthy amphibians. "This paper reports an examination of the shift from aboreal to 'flying' frogs where we evaluate the the aerodynamic performance consequences of both a behavioral and morphological change. 'Flying' frogs have evolved independently several times among the 3,400 species of anurans. Although the particular nonflying sister species to each flying form remains unknown, in all cases flyers are distinguished from related, nonaerial, aboreal frogs by a similar suite of morphological characters: enlarged hands and feet, full webbing on the fingers and toes, and accessory skin flaps on the lateral margins of the arms and legs. 'Flying' frogs are not capable of powered flight, but do travel considerable horizontal distances during vertical descent. They are technically classified as gliders because they can descend at an angle less than 45 to the horizontal ...

... Almost without exception, biology textbooks, scientific papers, popular articles, and TV documentaries convey the impression that an organism's genes completely specify the living animal or plant. In most people's minds, the strands of DNA are analogous to computer codes that control the manufacture and disposition of proteins. Perhaps our current fascination with computers has fostered this narrow view of heredity. Do our genes really contain all the information necessary for constructing human bodies? In the April 1994 issue of Discover, J. Cohen and I. Stewart endeavor to set us straight. The arguments against the "genes-are-everything" paradigm are long and complex, but Cohen and Stewart also provide some simple, possibly simplistic observations supporting a much broader view of genetics. Mammalian DNA contains fewer bases than amphibian DNA, even though mammals are considered more complex and "advanced." The implication is that "DNA-as-a -message" must be a flawed metaphor. Wings have been invented at least four times by divergent classes (pterosaurs, insects, birds, bats); and it is very unlikely that there is a common DNA sequence that specifies how to manufacture a wing. The connections between the nerve cells comprising the human brain represent much more information than can possibly be encoded in human DNA. A caterpillar has the same DNA as the butterfly it eventually becomes. Ergo, something more than DNA must be involved. [This observation does seem simplistic, because DNA could, in principle, code for metamorphosis.] Like DNA, this "something more" passing from ...

... Science Frontiers ONLINE No. 45: May-Jun 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Platypus Bill An Electrical Probe The bill of the duck-billed platypus has always looked kind of dumb -- as if Nature flushed with her success with polar bears (below) got careless when designing the platypus! How ignorant we were of Nature's genius. The platypus didn't borrow its snout from ducks but rather from the electric fishes. "That evolutionary enigma, the duckbilled platypus, has more than its egglaying to distinguish it from other mammals. It now appears that in common with some species of fish and amphibians, it can detect weak electric fields (of a few hundred microvolts or less). Not only that, but it uses its electric sense to locate its prey, picking up the tiny electrical signals passing between nerves and muscles in the tail of a shrimp." (Anonymous; "The Battery-Operated Duck-Billed Platypus," New Scientist, p. 25, February 13, 1986.) Reference. Mammal electrosensitivity is cataloged under BMO8 in Biological Anomalies: Mammals II.
