Geographic distribution patterns of Leguminosae and their relevance for the conservation of the Itacolomi State Park, Minas Gerais, Brazil

Abstract

This study identified patterns of geographic distribution of 102 Leguminosae taxa within the Park, based on literature data and herbarium specimens. Among the taxa, 38 grow exclusively in Campos Rupestres (rocky fields) and 49 in the Semideciduous Forest. Eleven patterns of geographic distribution were identified, of which the West-East-Central South America pattern was the most representative, with 27 taxa. Of the 102 sampled taxa of Leguminosae, five are endemic to the Espinhaço Range and ten are included in lists of endangered species of the flora of Brazil and Minas Gerais. Information on these taxa is crucial to provide conservation practices for conserving the vegetation formations of the PEIT.

A molecular phylogeny of the genus Diplusodon (Lythraceae), endemic to the campos rupestres and cerrados of South America

“…The first branch in the PG clade contains two sister species, one from the Canastra Arc (D. villosissimus Pohl) and one from the Plateau Goiano (D. gracilis Koehne from Serra Geral in Goiás State). In the Cerrado clade, we find a polytomy with five species of the Canastra Arc (D. and Leguminosae (Dutra & al., 2014;Rando & Pirani, 2011). The phylogenetic analysis of subtribe Lychnophorinae (Asteraceae-Vernonieae; Loeuille & al., 2015) shows a strongly supported clade of the campo rupestre endemic genus Heterocoma DC.…”

Environmental severity promotes phylogenetic clustering in campo rupestre vegetation

“…The region is characterized by Köppen as a Cwb climate, with cold and dry winters as well as hot and rainy summers (Peel et al 2007). The southern part of the Espinhaço Mountain Range in general and Itacolomi State Park in particular have been highlighted as a local hotspot of biodiversity due to a diverse landscape and the occurrence of many endemic species (Batista et al 2000;Dutra et al 2014).…”

Perfil metabolômico e avaliação biológica de espécies de Senna e Cassia

“…Comumente conhecida como a família das leguminosas, é um grupo com ampla distribuição que ocupa a terceira posição em número de plantas terrestres; com 730 gêneros e mais de 19.400 espécies, está atrás apenas das Orchidaceae e Asteraceae (RAHMAN, PARVIN, 2014). No Brasil, é representada por 212 gêneros e 2.717 espécies (DUTRA et al, 2014). Está presente nos seis biomas brasileiros e, por apresentar grande amplitude em termos de formas de vida, incluindo árvores, arbustos e plantas herbáceas perenes ou anuais, contribui de forma significativa com a diversidade paisagística observada nos diferentes biomas.…”
