Are they something more than funny little symbols symbols on a topographic map? They certainly are to the Ministry of Natural Resources! Wetlands provide very important important habitat for many forms of wildlife and plants, especially wild flowers; they provide spawning, and nursery areas for game fish; they provide areas for recreation recreation and outdoor education; they act' as water purifiers. Wetlands regulate the release of nutrients to downstream waters; stabilize soil; prevent erosion; act as buffers and prevent damage from storm and wave action; maintain ' i ground water levels; and regulate stream flow. Despite the importance of wetlands, they are being lost at an alarming rate. Only about 13 percent of the original 5.5 million acres of wetland in Southern Ontario [emain today. In parts of Southwestern Ontario, losses have reached 100 percent; while in Southern Ontario, as a whole, wetlands are being lost at roughly one to two percent per year. The Ontario Ministry of Natural Resources and Environment Environment Canada spent considerable considerable time and effort developing a wetland evaluation evaluation system for .Southern On J Toad's tongue No self-respecting WOODS, WATER AND WILDLIFE by Arlin Hackman - Federation Federation of Ontario Naturalists We've all been amazed by photographs showing frogs and toads zapping insects .for lunch with one lightning-fast flash of the tongue. But While you and 1 may be content to marvel at this display, persistent persistent investigation is needed to pin down the mechanics. Frogs and tôads catch fljes and bugs , with long sticky tongues which are then curled back into their mouths and the food gulped dowp. Toads tario. The system is designed to individually examine the different wetland values. The results are then combined for an overall rating of that wetland's value, which can then be compared to other wetlands. This system will help managers decide which wetlands are the most important, important, and which features of each wetland contribute most to that overall importance. The evaluation of Southern Ontario's wetlands has begun in earnest. Here in the Lindsay District, Ducks Unlimited and the Ministry of Natural Resources are involved involved in a co-operative project project that will see many of our local wetlands evaluated under the new system. Funding Funding for the project comes from a Federal-Provincial Job Creation Program under Section 38 df the Unemployment Unemployment Insurance Act.

These facts, and the • source of the vocal repertoire, repertoire, which has captifred our fancy over centuries, could be discovered by any observant naturalist. Finding out how their tongues work is a different different mailer. The traditional hypothesis that they operate' like a .crossbow when chasing food. But a rather esoteric piece of research has proven otherwise. To find this out, researchers researchers at the University of Michigan had to connect various muscle groups in the amphibians' throats, by hairlike hairlike wires, to machines that measured tiny changes in electrical' current. Using microcomputers, a 400 frame-per-second movie camera, and a technique called called synchronized elec* tromyography, they were able to measure voltage changes occurring when muscle muscle fibers were stimulated by * brain signals and thereby , isolate the major muscle groups involved in each action action of the tongue. It turns out that studies of a number of frog species revealed' that their tongues all work differently. differently. . 4 THE REGIONAL MUNICIPALITY OF DURHAM HOLIDAY CLOSURE OF SANITARY LANDFILL SITE The DARLINGTON WASTE DISPOSAL SITE will be closed Monday, .October 10, 1983, due to the 'Thanksgiving holiday. t Normal operations will continue on Tuesday, October October T1; 1983. - W.A.

More seriously, research like this often gives me an uneasy feeling about the uses to which laboratory animals are put. As Barbara Froom notes in her recent book Amphibians of Canada, excessive use of amphibians amphibians for research can contribute to the decline of some species. ' Yet, the pure research conducted conducted by Dr. Cans in Michigan does have its practical practical applications. Apparently his methods are being eagerly studied by dentists interested in treating muscle and bone abnormalities of the human mouth. It is also true that the insights are benefits we gain from research into plant and animal communities help to reinforce arguments for the protection of natural areas. Amateur naturalists needn't despair that future research methods will render thejr field observation and experience obsolete. The same article in the New York Times which reported this research also mistakenly identified the species Bufo Marinus as "the common frog". In fact it 'is a giant toad.
