The overall loss of biodiversity as well as the number of threatened plant species in the world has increased in recent years due to several anthropogenic pressures and/or environmental factors (Corral et al. (researchsquare.com)
Additionally, IUCN Red List database shows that plant extinctions are dominated by insular species, and the extinction data are associated with lower competitive ability and anthropogenic factors (Gray 2018). (researchsquare.com)

Habitats1
From an ecological point of view, the three species showed epidermal characters related to xeric habitats: thick cuticles, pubescence and great stomatal number. (techscience.com)
Traits3
In a common garden experiment using 30 annual Asteraceae species (neophytes, archaeophytes, plus some natives), grown in communities with or without legume presence, we measured functional traits and fitness in focal Asteraceae, as well as nitrogen characteristics of Asteraceae and two native community phytometer species. (springer.com)
In PCA analysis, the colpus length, width, and length/width ratio traits, polar and equatorial axes length, were the most variable features and some species were characterised by these characters. (akjournals.com)
Correct identification of Agoseris specimens can be assisted by knowing that species may exhibit variable traits (e.g., pubescence, corolla color, cypsela morphology), some species have leaf lobing variable on single plants (e.g., outermost entire versus inner lobed), and intermediate specimens may occur with any sympatric taxa.

In ecological terms, according to the moisture factor, most could be distinguished in the following ecological groups: 21 species to the mesophytic, 13 species to the xeromesophytes and 4 species to the hygromesophytes. (plantfungalres.az)
Pollen1
Pollen grain descriptions of most species were presented for the first time in the world. (akjournals.com)
Since legumes usually depend much less on soil N than non-leguminous species, they face less competition with neighboring plants and can even have facilitative effects on these (Temperton et al. (springer.com)
2016 ). In contrast, we here refer to indirect facilitative effects when neighboring species have additional soil N available as legumes use atmospheric N instead (Bessler et al. (springer.com)
In particular, we aimed to test the effect of forest soil disturbance on the abundance, richness, species composition, and functional guilds of microarthropods. (bvsalud.org)
This and other methods have been used to test for local adaptation in a number of species, especially in relation to human-induced increases in soil acidity but also in relation to changes in landscape structure (habitat fragmentation). (lu.se)
