Plant height

Plant height is measured in meters and relates to fully developed mature generative plants growing in the wild. The data were taken preferably from Kleyer et al. (2008), Guarino et al. (2019), Kaplan et al. (2019), French Flora database (2020) and complemented by additional sources such as national and regional floras. Each species is characterized by a mean value calculated across available datasets.

Specific leaf area

Specific leaf area (SLA) is the ratio of leaf area to leaf dry mass expressed in mm² mg^-1, reflecting the amount of energy plants invest in their leaf biomass. SLA is related to plant growth strategy with respect to water availability and temperature. The data were taken preferably from Kleyer et al. (2008), Tavşanoğlu & Pausas (2018), Ladouceur et al. (2019) and complemented by additional sources. Each species is characterized by a mean value calculated across available datasets.

Dispersal mode: Local non-specific dispersal, Anthropochory

?
Dispersal mode
Dispersal mode (dispersal syndrome, dispersal type) characterizes plant dispersal ability. It is represented by following categories: (i) local non-specific dispersal, which combines self-dispersal (autochory) and dispersal initiated by wind, where diaspores do not have any efficient special dispersal features, including several dispersal modes (namely ballochory, blastochory, boleochory, barochory); (ii) myrmecochory (ant dispersal); (iii) wind dispersal (anemochory), diaspores have special dispersal features such as hem, pappus, trichomes, dusty seeds or the species are tumbleweeds; (iv) animal dispersal includes dyszoochory, i.e. diaspores foraged by animals, which sometimes hide them as stock; (v) endozoochory, i.e. dispersal in animal gastrointestinal tract, and (vi) epizoochory, i.e., dispersal of diaspores attached on animal fur; special case is the (vii) anthropochory, i.e. human dispersal and (viii) hydrochory (water dispersal). Please note that hydrochory is not considered in the dispersal distance classes classification.

The dispersal modes are mainly estimated from species' morphological characteristics.

Dispersal distance class: 1, 7

?
Dispersal distance class
Dispersal distance classes are represented by ordered classes from 1 to 7, where classes 1 to 6 represent a gradient from short-distance dispersal to long-scale dispersal. The last class represents the dispersal mediated by humans. For species of the last class the assignment to the previous six classes and natural dispersal mode are given. The assignment of individual plants follows Lososová et al. (2023), a dataset prepared using the adjusted methodology of Vittoz & Engler (2007).

To assign plants into dispersal distance classes, several plant characteristics were obtained from various sources, namely plant height, life form, predominant dispersal mode, seed mass, typical habitat, plant geographical origin and information on dispersal by humans. In contrast to the original approach of Vittoz & Engler (2007), definitions of the dispersal distance classes were slightly modified.

Class 1 contains species shorter than 0.3 m. Their seeds do not have any specific dispersal features. Species are mostly self-dispersed, although seed dispersal can be initiated by wind, e.g., by shaking the fruit, which causes the diaspore to fall down. Class 2 is the most species-rich, including species with non-specific local dispersal strategy taller than 0.3 m. Class 3 includes ant-dispersed (myrmecochorous) species and wind-dispersed (anemochorous) forest herbs and dwarf shrubs. Class 4 is the least species-rich, including less efficient wind-dispersed woody plants and tumbleweeds. Class 5 includes wind-dispersed herbs and shrubs of open habitats and wind-dispersed trees with more efficient dispersal units (with trichomes). Class 6 includes species with different modes of animal dispersal. They can be dyszoochorous (i.e., foraged by animals, which sometimes hide them as stock), endozoochorous (i.e., dispersal in animal gastrointestinal tract), and epizoochorous (i.e., dispersal on animal fur). Finally, class 7 contains human-dispersed (antropochorous) species.

The species of the last class are also classified into one of the previous six classes based on their natural dispersal mode. Only classes 1-6 can be used in studies at the landscape scale where it is assumed that most species disperse naturally. All seven classes can be used in studies at a broader geographical scale where rare events of long-distance human dispersal are important.

Classes

Class 1. Small plants without any specific dispersal features. Mean dispersal distance: 0.1–1 m.

Class 2. Tall plants without any specific dispersal features. Mean dispersal distance: 1–5 m.

Class 3. Wind-dispersed plants of forest understorey and ant-dispersed plants. Mean dispersal distance: 2–15 m.

Class 4. Tumbleweed and wind dispersed trees and shrubs without trichomes. Mean dispersal distance: 40–150 m.

Class 5. Wind dispersed trees and shrubs with trichomes and wind dispersal plants of open habitats. Mean dispersal distance: 10–500 m.

Class 6. Animal dispersed plants. Mean dispersal distance: 400–1500 m.

Class 7. Human dispersed plants. Mean dispersal distance: 500 –5000 m.

Continentality

Continentality degree is derived from the position of species distribution range on the gradient from oceanic Western Europe to continental Middle Asia. The concept and data were taken from Berg et al. (2017), who revised and corrected a previous system of indicator values for continentality developed by Ellenberg et al. (1991). Higher values on the ordinal scale from 1 to 9 indicate species distributed in more continental areas. The species that extend over more than four regions assigned to different continentality classes as defined by Jäger (1968) are considered to be indifferent unless their lower continentality border is located in the regions assigned to continentality class 2 or higher.

Continentality amplitude

The concept and data were taken from Berg et al. (2017), who revised and corrected a previous system of indicator values for continentality developed by Ellenberg et al. (1991). Continentality degree is derived from the position of species distribution range on the gradient from oceanic Western Europe (class 1) to continental Middle Asia (class 10). Consequently, continentality amplitude corresponds to the number of phytogeographic continental classes where given species is distributed.
