Description
| - Práce se zabývá vlivem lokálních interakcí na regeneraci, růst, přežíváni a prostorové uspořádání jedinců smrku ztepilého a břízy pýřité během vývojového cyklu severského lesa, jehož dynamika nebyla dlouhodobě ovlivňována požáry. Výsledky prostorové analýzy ukazují na úzké spojení mezi smrkem a břízou. V boreálním lese se silně vyvinutým mechových patrem je úspěšnost regenerace smrkové populace silně závislá na přítomnosti břízy, jejíž lehce rozložitelný opad zvyšuje úživnost půdy, redukuje kompetici podrostu, provzdušňuje kořenovou zónu, která bývá díky přítomnosti albikového horizontu často zavodněná. Regenerace břízy je v nepřítomnosti požárů závislá na vývratech smrků a jejich tlejícím dřevě. (cs)
- 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 the abiotic 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 trees in 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 survival and l...
