...ht. In fact there is evidence to show cedar is not regenerating well in some areas now," Mathewes says. He says the forest industry has already taken note of his findings in deciding what kind of seedlings to use in replanting clearcuts. He also predicted that as a result of a warmer, drier climate, many small la......st tumors. It is known that molecules expressedin regenerating tissue are also expressed in tumors and, for that matter, duringmammalian development.

...ical counterparts, the algae can spread asexually, regenerating a new plant from barely visible fragments of itself. This has rendered all but useless any attempt to pull up the algae either by hand or by using the underwater equivalents of plows.
