摘要: . Since many wood-living forest species are influenced by the dynamics of coarse woody debris (CWD), information about spatial pattern CWD under natural conditions is essential to understand distributions. In this study we examined downed logs and wood-decaying fungi in an old-growth boreal Picea abies northwestern Sweden that governed gap-phase dynamics. The was studied draw conclusions dispersal abilities. A total 684 with a diameter > 10 cm were mapped analysed Ripley's K-function. distribution all taken together displayed significant aggregated up 45 m. different decay stages also deviated from random expectations. Fairly fresh middle stage clumped 25 35 m respectively, late decayed 95 Logs diameters 10–29 m, whereas ≥30 randomly distributed. result suggests gap-dynamics do have impact on CWD, creating fine-scale clumping. large may slightly regular spacing living trees. patterns 16 (n 20) Three aggregated, for Gloeophyllum sepiarium, Coniophora olivacea Vesiculomyces citrinus. These results indicate most at stand level generally not limitations.
