Zróżnicowanie flory roślin naczyniowych dawnych wyrobisk po wydobyciu rud kruszcowych jako lokalnych centrów różnorodności florystycznej na tle uwarunkowań siedliskowych

Abstract

Mining and ore processing inevitably causes an interference with multiple components and resources of the natural environment, which leads to the substantial changes to the functioning of the native ecosystems (...). The aim of this work is to evaluate the role of the environmental conditions on the process regarding creation of the local centers of floristic diversity, as well as assessing their influence on the appearance of specific functional traits of plant species which can help to understand the range of variation among the various indicators relating to the functional diversity. In order to do this, the study plots were established among the 30 old remnants of the ore mining together with their surroundings which are located in two distinctive types of biotopes – forest and farmland areas (split into two halves) (...). Functional traits related to the type of life strategy were positively related to the environmental factors (mainly content of bioavailable heavy metals) and traits which described competitive capabilities of plant species (SLA, age of first flowering, persistence of the soil seed bank) had negative relations with the environmental parameters. In both biotopes, the indices related to the functional diversity had higher mean values in the group of surrounding areas compared to the mounds which can indicate that plant species inhabiting non-transformed areas are more optimized for the utilization of the available resources.
