The global loss of floristic uniqueness [PDF]

open access: yes, 2021
International audienceRegional species assemblages have been shaped by colonization, speciation and extinction over millions of years. Humans have altered biogeography by introducing species to new ranges. However, an analysis of how strongly naturalized

Floristic Similarities between the Lichen Flora of Both Sides of the Drake Passage: A Biogeographical Approach

open access: yesJournal of Fungi, 2023
This paper analyses the lichen flora of Navarino Island (Tierra del Fuego, Cape Horn Region, Chile), identifying species shared with the South Shetland Islands (Antarctic Peninsula). In this common flora, species are grouped by their biogeographic origin (Antarctic–subantarctic endemic, austral, bipolar, and cosmopolitan), their habitat on Navarino ...

Comparing Floristic Diversity between a Silviculturally Managed Arboretum and a Forest Reserve in Dambulla, Sri Lanka [PDF]

open access: yesJournal of Tropical Forestry and Environment, 2014
Repeated slash and burn cultivation creates wasteland with thorny shrubs, which then takes a long time to become secondary forests through serial stages of succession. Assisted natural regeneration through silvicultural management is a useful restoration

Similar understorey structure in spite of edaphic and floristic dissimilarity in Amazonian forests [PDF]

open access: yesActa Amazonica, 2015
Forest structure determines light availability for understorey plants. The structure of lowland Amazonian forests is known to vary over long edaphic gradients, but whether more subtle edaphic variation also affects forest structure has not beenresolved.

Rubiaceae in Brazilian Atlantic Forest remnants: floristic similarity and implications for conservation

open access: yesRevista de Biología Tropical, 2016
<p>The Atlantic Forest presents great biological complexity and high richness and endemism levels, but it is one of the most threatened phytogeographic domain on the planet. Brazil is one of the Rubiaceae diversity centers in the Neotropics. The relevance and representativeness of the Rubiaceae family in the Atlantic Forest is highlighted in ...

Floristic Relationships Among Vegetation Types of New Zealand and the Southern Andes: Similarities and Biogeographic Implications [PDF]

open access: yesAnnals of Botany, 2008
Similarities between the floras of geographically comparable regions of New Zealand (NZ) and the southern Andes (SA) have interested biologists for over 150 years. The present work selects vegetation types that are physiognomically similar between the two regions, compares their floristic composition, assesses the environmental factors that ...

Effects of introduced species on floristic similarity: Comparing two US states

open access: yesBasic and Applied Ecology, 2008
Abstract This study aims to examine the effects of introduced species on increasing (homogenizing) or decreasing (differentiating) floristic similarity of plant composition. We calculated the Jaccard index for each pair of counties within two states of USA, California and Florida.

Orchidaceae in an Atlantic Forest area: floristics and similarity to other Dense Ombrophilous Forest fragments [PDF]

open access: yesActa Botanica Brasilica, 2015
The Brazilian Atlantic Forest is considered a global hotspot for biodiversity although it is currently threatened and highly fragmented. Orchidaceae in this phytogeographical domain is represented by 148 genera, of which 142 are endemic; Rio de Janeiro State contains approximately one third of all Brazilian orchid species.
