Název v původním jazyce

Neighborhood interactions influencing tree population dynamics in nonpyrogenous boreal forest in northern Finland

Popis výsledku v původním jazyce

Open-canopy moss-rich woodlands dominated by Picea abies and Betula pubescens in northern Finland may undergo cyclic development with reciprocal replacement of the tree species due to the positive feed-backs on soil conditions. Although relations to theabiotic environment are well understood,intra-and interspecific interactions during development of sparse boreal forests have received less attention. We studied tree regeneration,growth and survival with respect to size and density of neighboring treesin four stands representing roughly four stages of the Picea Betula forest cycle.We conducted spatial analysis (Ripley 's K -function)of mapped locations of live and dead stems to reconstruct the distribution of stems prior to mortality,and to infer possible causes of tree population decline.The prevalence of standing dead stems enabled us to test if mortality was associated with density and size of neighboring trees. Logistic regression was used to test for relationships between tree su
