Evaluating the reliability and validity of the Icelandic translation of the Mini-BESTest in rehabilitation patients: an international implication for balance assessment.

Background: The Mini-BESTest (Balance Evaluation Systems Test) is a standardized balance evaluation tool. The psychometric properties of the Mini-BESTest are being established around the world.

Purpose: This study aimed to evaluate the reliability and validity of the Icelandic translation of the Mini-BESTest.

Morphological variation among Betula nana (diploid), B. pubescens (tetraploid) and their triploid hybrids in Iceland.

Background And Aims: Introgressive hybridization between two co-existing Betula species in Iceland, diploid dwarf birch B. nana and tetraploid downy birch B. pubescens, has been well documented.

Classifying seedlots of Picea sitchensis and P. glauca in zones of introgression using restriction analysis of chloroplast DNA.

Chloroplast DNA (cpDNA) restriction analysis was used to classify five reforestation seedlots as to species. The material included two Sitka spruce (Picea sitchensis (Bong.) Carr.
