Ecological background of crown condition, growth and nutritional status of Picea abies (L.) Karst. in the Bavarian Alps

, : Ecological background of crown condition, growth and nutritional status of Picea abies (L.) Karst. in the Bavarian Alps. European Journal of Forest Research 124(1): 9-18

Using a representative sample of stands from a cross section through the Bavarian portion of the northern Calcareous Alps, this study evaluates the plausibility and significance of causal hypotheses for an explanation of the poor crown condition of Norway spruce in mountain forests: (1) ozone exposure in conjunction with (a) drought and (b) ample water supply; (2) soil-borne nutrient deficiency; (3) drought; and (4) tree age.

Two new methods are derived for inferring the mode of growth of individual microbial cells from measurements made of the volume distributions of populations. One is based on statistics of the observed distribution and has the particular advantage...

We prove that this distribution obeys the power law with the e...
