Temporal changes of forest species composition studied by compositional data approach

Abstract: Many ecological data are compositional and different quantitative techniqueshave been used to analyze such data, albeit some of them being methodologically wrong. The aim of this contribution is to apply the compositional data approach to forestry data and demonstrate the strengths of this method for percentage or relative data with infrequent zero values. Basal areas of three dominant tree species (Abies alba, Picea abies, Fagus sylvatica) in 119 forest compartments in some of the Omphalodo-Fagetum forests in… Show more

“…A research site lying between 820 and 871 m above sea level was selected in one of the forest compartments (No. 34) after reviewing the data from forest management plans for the period from 1890 to 2004, also used and analyzed in several studies in Leskova dolina [37,39].…”

“…Absolute deviation of OLR. The influence was analysed by the changes of ILR and OLR [60], which are shown in Table 2. The longwave radiation value of the open space without space elements (C1) is used as the reference (average), and the absolute deviation of longwave radiation value of each type is calculated.…”

“…Responses can also be continuous, such as Gaussian (Anderson, 1958) or compositional data (Aitchison and Egozcue, 2005;Hijazi and Jernigan, 2009). Of particular interest are compositional data which consist of proportions or percentages of disjoint categories summing up to one, and play an important role in many fields such as ecology (Kobal et al, 2017;Douma and Weedon, 2019), geology (Buccianti and Grunsky, 2014;Engle and Rowan, 2014), genomics (Tsilimigras and Fodor, 2016;Shi et al, 2016;Washburne et al, 2017) or medicine (Dumuid et al, 2018;Fairclough et al, 2018).…”
