Floristic richness comparison among the Mexican states [PDF]
The number of native vascular plant species recorded in each of the 32 Mexican states was evaluated to identify and compare their floristic richness values and determine their floristic similarities.

Floristic similarity and dispersal syndromes in a rocky outcrop in semi-arid Northeastern Brazil. [PDF]
Floristic studies provide valuable information on species richness in a region, and are particularly important if these areas belong to less studied environments, such as rocky outcrops, that may increase our knowledge. An important aspect for species colonization includes the mechanisms of diaspores dispersal in each community; these are essential to ...

Connectionism and psychological notions of similarity [PDF]
Kitcher (1996) offers a critique of connectionism based on the belief that connectionist information processing relies inherently on metric similarity relations. Metric similarity measures are independent of the order of comparison (they are symmetrical)

The Plurality of Melodic Similarity [PDF]
Melodic similarity is a much-researched topic. While there are some common paradigms and methods, there is no single emerging model. The different means by which melodic similarity has been studied are briefly surveyed and contrasts drawn between them ...

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 ...

FLORISTIC SIMILARITY IN A FOREST-SAVANNAH ECOTONE IN WESTERN BAHIA STATE, BRAZIL
This study aimed to generate knowledge about transition areas between phytophysiognomies for the understanding and conservation of these unique environments. Thus, the existence of different floristic groups was analyzed in a spatial gradient of an ecotone in the municipality of São Desidério, state of Bahia, Brazil.

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

Impact of Anthropogenic Activities and Climate Change on the Wetlands in the North-West of Madagascar. [PDF]
ABSTRACT Macrophytes are vulnerable to various factors in their natural ecosystems, including climatic, ecological, and anthropogenic changes. This study aims to document how these factors influence floristic composition. Four sites were investigated in the Boeny Region of northwest Madagascar: Ambatoboeny, Marovoay, Ankarafantsika National Park, and ...
