The formation of a temporary pond is an annual event, which on Prince 
     
     Edward Island may begin as early as January or February during a mild, wet 
     
     winter. Initially, there is little pond life because of frequent freezing, and 
     
     daylight is not long enough to entice prospective residents to begin their 
     
     annual cycle. In late March or early April, residents begin to appear. Some 
     
     migrate to the pond while others hatch from dormant eggs or cysts buried under- 
     
     ground. Spring peepers and green frogs arrive in April to court, mate, deposit 
     
     their gelatinous eggs and depart. By early May, the temporary ponds are teeming 
     
     with life. Microscopic animals eat fresh and decaying vegetation on the bottom, 
     
     and they in turn are fed on by crustaceans and aquatic insects. Black ducks 
     
     use these temporary ponds for feeding and courtship. 
     
    

    
     Most ponds begin to disappear in May, and by early June the water is usually 
     
     gone. By this time, some young amphibians have developed. Insect eggs have 
     
     hatched, matured, and emerged adults have flown away. Some which remain go down 
     
     into the m0ist SOil, or form dormant eggs or cysts which can tolerate the ensuing 
     
     dessication. For many animals the disappearance of the pond means death. Nymphs 
     
     of insects not yet matured and some unhatched eggs are destroyed. Tadpoles that 
     
     fail to reach adult form before the water disappears, perish. When the pond has 
     
     dried up the only eVidence of its recent aquatic condition is the occurrence of 
     
     mg;:t:;eflOVing grasses and sedges. In cultivated fields, the evidence is even 
     
    

    
     VlOUS. 
     
    
   
   
    
     Nine months later, the pond will fill again and the cycle starts anew. 
     
    
   
   
    
     NEW BOOK DUE Watershed Red - The Life of the Dunk River, Prince Edward Island 
     
     is the title of a new book slated for release in March of this year. Written 
     
    

    
     by Kathy Martin, Watershed Red is of particular interest to members of the 
     
    

    
     Natural History Society., Not only is it written by an active society member and 
     
     former editor of this newsletter, but it also contains a wealth of fascinating 
     
     detail about the natural history of the province. 
     
    

    
     Bubbling up from a tiny spring in the corner of a Srington pasture, the 
     
     headwaters of the Dunk wind their way westward through a rich variety of land— 
     
     scapes before emptying into Bedeque Bay. Along this route dozens of small 
     
     tributaries each make a contribution to the river, tying the region together 
     
     as a distinct watershed. . 
     
    

    
     The Dunk watershed provides homes and livelihoods for a multitude of living 
     
     creatures, from the aging beeches of the Rose Valley hills to the busy muskrats 
     
     of the Bedeque marshes. Using the common denominator of the life-giving water— 
     
     way, the author explores the lives of its inhabitants and the web of relation— 
     
     ships that bind them into the community of the Dunk. 
     
    

    
     Watershed Red is being published by Ragweed Press, with the assistance of 
     
     the University of Prince Edward Island. The book contains about 200 pages. 
     
     Illustrations are by Connie Pound-Gaudet. Copies are available from Ragweed
