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

Floristic composition and similarity of 15 hectares in Central Amazon, Brazil
Revista de Biología Tropical, 2018 The Amazon region is one of the most diverse areas in the world. Research on high tropical forest diversity brings up relevant contributions to understand the mechanisms that result and support such diversity. In the present study we describe the species composition and diversity of 15 one-ha plots in the Amazonian terra firme dense forest in Brazil ...

A generalized framework for analyzing taxonomic, phylogenetic, and functional community structure based on presence-absence data [PDF]
, 2018 Community structure as summarized by presence–absence data is often evaluated via diversity measures by incorporating taxonomic, phylogenetic and functional information on the constituting species.

Revista 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 ...

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

Seedling Emergence from Seed Banks in Ludwigia hexapetala-Invaded Wetlands: Implications for Restoration [PDF]
, 2019 Soil seed banks play a critical role in the maintenance of wetland plant communities and contribute to revegetation following disturbances. Analysis of the seed bank can therefore inform restoration planning and management.

Elevational and latitudinal changes in tree associations and diversity in the Eastern Arc mountains of Tanzania [PDF]
, 1996 A total of 200 variable-area plots covering 20 3 ha containing 4000 trees with a basal area of 921 4 m2 were assessed over a combined elevational range of 410-2180 m in the moist forests of three Tanzanian Eastern Arc mountains: West Usambara, Nguru and ...

Annual of Sofia University "St. Kliment Ohridski", Faculty of Biology, Book 2 - Botanics, 2023 The present paper provides first detailed data on the phytoplankton species composition collected during two summer campaigns (2019 and 2021) from 21 Bulgarian microreservoirs (<100 ha). By conventional light microscopy (LM) 414 algae from seven phyla were identified, among which Chlorophyta were the taxonomically richest group (143 taxa).
