Growth Rates of Important Reindeer Forage Lichens on the Seward

ABSTRACT. The average annual linear rates of growth of Cladonia alpestris, C. rangiferina, and C. sylvatica on the Seward Peninsula, Alaska, were determined to be 5.0, 5.3, and 5.4 mm. respectively. These averages are higher than those of northern Canada and some areas in the U.S.S.R. Cladonia rangi...

Description
Summary:ABSTRACT. The average annual linear rates of growth of Cladonia alpestris, C. rangiferina, and C. sylvatica on the Seward Peninsula, Alaska, were determined to be 5.0, 5.3, and 5.4 mm. respectively. These averages are higher than those of northern Canada and some areas in the U.S.S.R. Cladonia rangiferina reaches the podetium renewal period in 5.9 years which is almost half the time required by the other two species. RÉSUMÉ. Taux de croissance d'importants lichens fourragers du renne, dans la Péninsule de Seward, Alaska. Les taux linéaires moyens annuels de croissance de Cladonia alpestris, C. rangiferina et C. sylvatica dans la péninsule de Seward, Alaska, ont été établis respectivement à 5, 5.3 et 5.4 mm. Ces moyennes sont plus grandes que celles du nord du Canada et de quelques régions de l'U.R.S.S. Cladonia rangiferina atteint sa période de renouvellement du 2odétium en 5.9 années, ce qui est à peu près la moitié du temps requis par les deux autres espèces. PE3K)ME.
