Resumo Mimoseae, uma das tribos do clado Mimosoide - Leguminosae, possui 41 gêneros e cerca de 860 espécies. No Brasil, está representada por 16 gêneros e 614 espécies. Dada relevância do grupo para a flora brasileira e para a Mata Atlântica, este trabalho apresenta o estudo florístico dos gêneros Anadenanthera, Leucaena, Neptunia, Parapiptadenia,...

... considered Espírito Santo state as one of the four high biodiversity centers of endemism in the Atlantic Forest domain. In a special volume of "Flora do Espírito Santo" published by Rodriguésia in 2017, there are several floristic and taxonomic studies comprising 21 families, 60 genera and 290 species of ferns and angiosperms (Carrijo & Mansano 2017), as well as 80 new records of taxa for the state (Freitas & Alves-Araújo 2017;Martins et al. 2017;Silva et al. 2017;Bacci et al. 2017;Flores et al. 2017;Lírio & Peixoto 2017;Luber et al. 2017; Iglesias & Dutra 2017). This shows the importance of new studies about the Flora of Espírito Santo. ...

... In Espírito Santo, Mimosa is represented by 23 taxa belonging to 22 species, which is 51.1% of the Mimoseae species in the state (Silva et al. 2017) and 17.9% of the Mimosa species in the Atlantic Forest domain (BFG 2018). Mimosa is associated with grassland formations ("campestres") and disturbed areas (Dutra & Garcia 2014) and is well represented in all Brazilian biomes (Simon & Proença 2000;Dutra & Garcia 2014). ...
This paper is a taxonomic treatment of the species of Mimosa (Leguminosae) in the state of Espírito Santo, Brazil. The analyses were from herbarium specimens and field expeditions between April 2014 and July 2015. The genus is represented by 22 species, including seven new species records for the Flora of Espírito Santo list. We provide an identification key, morphological descriptions, distribution maps, illustrations and comments on the taxonomy and geographic distribution.
Beta diversity measures changes in species composition and, if partitioned, isolates the contributions of turnover and nestedness in such differences. High beta diversity values have been reported to ant assemblages found at the soil surface, tree canopy and underground soil layers. However, studies on ant assemblage at small-scale stratification have drawbacks regarding to sampling designs and on the searching of turnover and nestedness patterns contribution to overall beta diversity. We investigated how ant assemblage beta diversity changes along the epigaeic-hypogaeic and epigaeic-arboreal gradients in a Neotropical rainforest remnant and whether this change is driven by turnover or nestedness. We sampled ants at different depths/heights and calculated the Jaccard index between the ants sampled at these strata and the ones at the soil surface as an overall beta diversity measurement. Then, we partitioned the Jaccard index to account for turnover and nestedness separately. Overall beta diversity values did not significantly change, being consistently high along both gradients. Turnover’s proportional contribution to beta diversity significantly increased with increasing height but did not significantly change with increasing depth. Turnover values were high throughout the subterranean gradient. This suggests that epigaeic ants better explore low heights than low depths. Our results revealed that the assemblages from both gradients are continuously different from the soil assemblage, that this difference is mainly due to turnover, and that turnover’s importance increases along the epigaeic-arboreal gradient. These conclusions were only possible due to isolating the effects of turnover and nestedness, reinforcing the importance of doing so.
The Atlantic Forest is one of the most threatened biomes in the world. Despite that, this
biome still includes many areas that are poorly known floristically, including several
protected areas, such as the "Floresta Nacional do Rio Preto" ("Flona do Rio Preto"),
located in the Brazilian State of Espírito Santo. This study used a published vascular plant
species list for this protected area from the "Catálogo de Plantas das Unidades de
Conservação do Brasil" as the basis to synthesise the species richness, endemism,
conservation and new species occurrences found in the "Flona do Rio Preto"
