Cryptogamie, Bryologie, 2017 The south-eastern Brazil comprises the Atlantic forest (a region mainly characterized by tropical evergreen forest), subtropical forest, mangroves, and scrub sandbanks. Sandy areas are found at sea level, and high altitude grassland spots and rocky outcrops occur above 2000 m.

Computer assisted floristic similarity analysis
Folia Geobotanica Et Phytotaxonomica, 1971A program for polythetic numerical evaluation of phytosociological material is described. Using Sorensen's coefficient of floristic similarity it computes the homogeneity of subjectively chosen sets of releves, the affinity of each constituent releve to the set as well as the similarity between any pair of sets.

Delimitation and ranking of floristic-sociological units on the basis of relevé similarity
Plant Ecology, 1977The present information deals with the possibility of using coefficients of releve similarity for the delimitation of units in floristic-sociological synsystematics in the sense as used by the Braun-Blanquet approach.

Estimation of the mean floristic similarity between and within sets of vegetational relevés
Folia Geobotanica Et Phytotaxonomica, 1966Various possibilities of usingSorensen’s coefficient of floristic similarity in plant sociology are summarized. A new formula (11). derived from that bySorensen and based on constancy values, is suggested in order to calculate the mean floristic similarity within a set of releves.

Urban Forestry and Urban Greening, 2021
Abstract Urban green spaces play an important role in improving the quality of life and sustainability in cities and require careful empirical evaluation. This study looked into the contradiction of native species being underrepresented in urban environments in Brazilian Amazon cities, compared to exotic species that have been introduced.

Biodiversity, 2015
The floras of mountain ranges, and their similarity, beta diversity, and endemism, are indicative of processes of community assembly; they are also the initial conditions for coming disassembly and reassembly in response to climate change. As such, these characteristics can inform thinking on refugia.

Upward shift of alpine plants increases floristic similarity of mountain summits
Journal of Vegetation Science, 2007AbstractQuestion: Does the upward shift of species and accompanied increase in species richness, induced by climate change, lead to homogenization of Alpine summit vegetation?Location: Bernina region of the Swiss Alps.Methods: Based on a data set from previous literature we expand the analysis from species richness to beta‐diversity and spatial ...

FLORISTIC SIMILARITIES AMONG 51 REGIONS OF THE SOVIET UNION BASED ON THE BRASSICACEAE
TAXON, 1982SummaryFloristic similarities among 51 geographic regions in 7 superregions of the Soviet Union were analyzed using distributonal data of 736 species of the Brassicaceae. Due to the high number of species, they were grouped into 9 tribes before analysis.

Studies undertaken in the Atlantic Coastal Forest have revealed a notable floristic heterogeneity within this vegetation type in NE Brazil. However, there is still a great need for detailed comparisons of the floristic relationships between the various forest types found there.
