In search of a perfect trait set: A workflow presentation based on the conservation status assessment of Poland's dendroflora

“…As some parts of the trait values were still missing and we did not want to exclude less represented species, we performed data imputation based on correlations among traits and between traits and phylogeny (Pyšek et al, 2015), using an approach analogous to Dyderski and Jagodziński (2021). As previously stated, we only imputed data for the traits that had at least 25% completeness with measured values obtained from databases and other sources used (CABI, 2020; Kaźmierczakowa et al, 2014, 2016; Rutkowski, 2006; Wild et al, 2019; Zieliński, 1987, 2004). We imputed missing values using the random forest method from the missForest package (Stekhoven & Bühlmann, 2012) as recommended by Penone et al (2014).…”

“…The values presented are from before the imputation of trait values. Rutkowski, 2006;Wild et al, 2019;Zieliński, 1987Zieliński, , 2004. We imputed missing values using the random forest method from the miss-Forest package (Stekhoven & Bühlmann, 2012) as recommended by Penone et al (2014).…”

“…We downloaded data for all traits that were available for our species. Then, we completed as much missing data as possible, searching for information in botanical handbooks, identification keys, and red lists of threatened species (CABI, 2020; Kaźmierczakowa et al, 2014Kaźmierczakowa et al, , 2016Rutkowski, 2006;Wild et al, 2019;Zieliński, 1987Zieliński, , 2004. These were mainly information on flowering onset, dispersal factors, leaf life span, nectar accessibility, and nectar amount.…”

“…We prepared a list of 387 woody species occurring in Poland. To include the whole dendroflora, accounting for trees, shrubs, and subshrubs (i.e., species characterized by the lignification of only the lower parts of the shoots, species only weakly woody or species that are woody but survive only a few growing seasons), we compiled data from numerous sources (CABI, 2020;Kaźmierczakowa et al, 2014Kaźmierczakowa et al, , 2016Rutkowski, 2006;Wild et al, 2019;Zieliński, 1987Zieliński, , 2004. We included both native and non-native species.…”

Does the Distance from the Formal Path Affect the Richness, Abundance and Diversity of Geophytes in Urban Forests and Parks?

“…Thepercentage of total vegetation cover and the height of the tallest plant were measured following Kostrakiewicz-Gierałt et al [36], whereas the cover-abundance of each species was estimated using the Braun-Blanquet method [41] and following data transformation by Kostrakiewicz-Gierałt et al [36] as well. The identification of vascular plants was based on the morphological features provided by Csapodý [42], Muller [43] and Rutkowski [44], and the nomenclature was adopted from POWO [45]. Life forms and classification of geophytes followed the Bi-olFlor database [46,47].…”
