First data on the summer phytoplankton composition of 21 microreservoirs in Bulgaria andtheir floristic similarity

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).

Multi-scale comparisons of tree composition in Amazonian terra firme forests [PDF]

Biogeosciences, 2009
We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the species-level analysis more clearly distinguishes among ...

Patterns of turnover and floristic similarity show a non-random distribution of naturalized flora in Chile, South America [PDF]

Revista chilena de historia natural, 2008
La distribucion geografica actual de especies exoticas puede ser informativa de los procesos involucrados en las invasiones biologicas facilitadas por humanos. Debido a que los factores ambientales y antropicos pueden afectar la distribucion geografica de plantas exoticas, hipotetizamos que las plantas naturalizadas deberian exhibir una distribucion no
