An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lian...

The relationships between rarity (i.e., range-size, local abundance) and niche-breadth can be important to assess the risks the species face under global change, namely those resulting from fire regime change. In fire areas, germination is critical for establishing after fire for many species. We examined the relationships between rarity and germination niche-breadth for 53 plant species of two life-forms (chamaephytes and hemicryptophytes) growing in Eastern Spain. Rarity was measured as geographic range-size and as local abundance. Local abundance was evaluated at two sites differing in their post-fire successional status (a recently burned area and a long-unburned one). Germination niche-breadth was measured as the mean germination evenness index from four germination experiments that subjected the seeds to various germinating conditions characteristics of fire environments. Correlations between rarity (range-size, local abundance) and niche-breadth were calculated in cross-species mode or by way of phylogenetically independent contrasts, and either for the 53 species (all-species set) or for each of two life-form groups (chamaephytes, hemicryptophytes). In general, no significant correlations were found between the rarity measures and germination nichebreadth for the all-species set. However, significant correlations emerged when the analyses were done separating species by life-forms. Germination nichebreadth was positively correlated with range-size for chamaephytes, and negatively for hemicryptophytes. In addition, germination niche-breadth was uncorrelated, or negatively so, with local abundance for chamaephytes and hemicryptophytes, respectively. While no correlation between range-size and local abundance was found for chamaephytes, a negative one was obtained for hemicryptophytes. We conclude that rarity/germination-niche relationships varied by life-form. This pattern of relationships was obscured when all species were joined in a single group. Based on the contrasting patterns of correlations obtained for each life-form we argue that the changes in the germinating environment caused by alterations in fire regime are likely to differentially affect these two groups of species.

The oligarchy hypothesis proposes that large areas of Amazonian plant communities are dominated by limited sets of species. We tested this hypothesis by (1) quantifying dominance of the 10 most common species, genera and families in each region; and (2) assessing the consistency of relative abundance ranks between areas and across scales in dominance patterns for trees and lianas in two distant Amazonian regions (∼1900 km), the Yasuní and Madidi National Parks in Ecuador and Bolivia, respectively. The analyses were based on sixty-nine 0.1-ha plots in which all woody plants with a diameter at breast height (dbh) ≥2.5 cm were inventoried (19 775 individuals and 1729 species in total). The plots were located at two Yasuní and five Madidi sites, with an average of 10 plots per site. Overall, oligarchic dominance was pronounced at all the spatial scales investigated, although decreasing with increasing scale. Cross-scale relative abundance ranks were more consistent in Yasuní than in Mad...
