Climatic conditions affect shoot flammability by influencing flammability‐related functional traits in nonfire‐prone habitats

“…Aridity Index for each location (the ratio of MAP to mean annual reference evapotranspiration) was extracted from Global Aridity Index and Potential Evapo‐Transpiration (ET0) Climate Database v.2 (0.5‐arc min resolution, Zomer et al ., 2022). Mean annual temperature, MAP, and AI were analyzed as they are among the most important environmental factors influencing plant traits (Wright et al ., 2017; Baird et al ., 2021; Harris et al ., 2022). Sexton et al .…”

“…Aridity Index for each location (the ratio of MAP to mean annual reference evapotranspiration) was extracted from Global Aridity Index and Potential Evapo-Transpiration (ET0) Climate Database v.2 (0.5-arc min resolution, Zomer et al, 2022). Mean annual temperature, MAP, and AI were analyzed as they are among the most important environmental factors influencing plant traits (Wright et al, 2017;Baird et al, 2021;Harris et al, 2022). Sexton et al (2009) hypothesized that if gene flow occurs among populations of a given species across its native range, then the mean phenotypic trait values of this species will be related to their mean climate variables.…”

“…Sexton et al (2009) hypothesized that if gene flow occurs among populations of a given species across its native range, then the mean phenotypic trait values of this species will be related to their mean climate variables. In addition, previous studies suggested that the bioclimatic envelope of a species tends to remain unchanged over space and time (Pearman et al, 2008;Wiens et al, 2010;Harris et al, 2022). Therefore, we used the average values of climatic variables from all occurrence locations of each species to represent the bioclimatic envelope of the species.…”

Evaluating plant lineage losses and gains in temperate forest understories: a phylogenetic perspective on climate change and nitrogen deposition

“…We restricted this study to angiosperms to prevent inflated overdispersion due to gymnosperms and pteridophytes linked to deep phylogenetic nodes. Baseline surveys occurred Lost species are phylogenetically clustered subsets of the habitat species pool (Vamosi & Wilson, 2008;Eiserhardt et al, 2015), while gained species include distantly related species with diverse traits (Li et al, 2015) (H2) Species' losses and gains across communities are not randomly distributed across the phylogeny Environmental tolerances are often phylogenetically conserved (Cavender-Bares et al, 2004;De Pauw et al, 2021;Harris et al, 2022a) (H3) Species' losses and gains across communities are associated with phylogenetically conserved plant traits Abiotic filters operate on phylogenetically conserved plant traits and their related ecosystem functions (Keddy, 1992;Dı ´az et al, 1998) (H4) Lost species are more phylogenetically clustered than gained species within communities Lost species share conserved traits that make them intrinsically vulnerable to extinction (Vamosi & Wilson, 2008;Eiserhardt et al, 2015). Gained species include distantly related species with diverse traits (Li et al, 2015) (H5) Lost and gained species are phylogenetically distantly related to persisting species Abiotic filters exclude subsets of closely related species with ecological strategies distinct from those of persisting species (Eiserhardt et al, 2015).…”

“…The amount of evolutionary history lost and gained following extinction and colonization events depends on the rate of evolution of ecological traits (Cavender‐Bares et al ., 2004). Because traits related to environmental tolerances are often phylogenetically conserved (Hawkins et al ., 2014; De Pauw et al ., 2021; Harris et al ., 2022a), environmental changes are likely to promote the extinctions of close relatives (Vamosi & Wilson, 2008; Eiserhardt et al ., 2015). In such cases, lost species would represent distinct phylogenetically clustered subsets of the habitat species pool and be phylogenetically different from persisting species.…”
