Structural Attributes Outweigh Topographical Effects in Determining Vascular Plant Diversity Within Southern Apennine Old-Growth Forests. [PDF]

Ecol Evol
Forest structure accounted for a larger unique fraction of vascular plant compositional variation in Southern Apennine old‐growth forests (23.5%) than topography alone (12.8%), with a substantial shared contribution between the two predictor sets.

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 ...

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

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 ...

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).

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

Annals 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

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.

Thematic relations affect similarity via commonalities [PDF]

, 2009
Thematic relations are an important source of perceived similarity. For instance, the rowing theme of boats and oars increases their perceived similarity. The mechanism of this effect, however, has not been specified previously.
