“…is an example of a rare bromeliad, which is restricted to 2 places in Minas Gerais State, Brazil, 30 km apart: Ibitipoca State Park, a State conservation unit, and Serra Negra, an unprotected area (Versieux, 2011). Both locations belong to the Mantiqueira Range Complex and are characterized by a steep relief with altitudes ranging from 900 to 1794 m and heterogeneous vegetation composed of a mosaic of rocky fields and forest fragments (Menini et al, 2009). The species can be seen in the rocky landscapes mainly at altitudes higher than 1400 m (Monteiro and Forzza, 2008).…”

ABSTRACT. Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra). The 2 areas belong to the Mantiqueira Mountain Range Complex; both are characterized by steep relief with high altitudes and by heterogenic vegetation formed by a mosaic of rocky fields and forest fragments. According to International Union for Conservation of Nature criteria, V. cacuminis is designated as "vulnerable". We examined the genetic variability and population structure of 70 individuals (3 populations) of V. cacuminis, using 16 ISSR markers. Although V. cacuminis is considered a rare species, the estimated genetic diversity was found to be relatively high (Shannon index = 0.33; percentage : 1934-1943 (2013) Genetic variability of Vriesea cacuminis of polymorphic bands = 87%). The populations were found not to be structured (AMOVA test, Φ ST = 0.16), probably due to the cross-breeding. Based on Bayesian analysis, this species includes one cluster containing the populations from Ibitipoca State Park and another cluster including the population from Serra Negra. This information will help determine strategies to maintain the genetic variability of these populations.

“…According to Carvalho-Silva and Guimarães (2008), Peperomia is predominant in Dense Ombrophilous Forests, and less frequent in Seasonal Forests, in which humidity levels are low, as confirmed by Menini Neto et al (2009b), who found it to be the most representative genus of epiphytes in a Riverine Forest in the Zona da Mata of MG. However, Cervi and Borgo (2007) found Peperomia to be the most representative genus in a fragment of Seasonal Semideciduous Forest, similar to the results of this study.…”

“…In general, these families are the five most representative in the epiphytic synusia both in the Atlantic Forest (KERSTEN, 2010) as well as globally (MADISON, 1977), occupying however, a different position to that found in FFS. Orchidaceae is frequently the richest family in studies concerning epiphytic flora in the Neotropical Region, followed by Bromeliaceae (DISLICH; MANTOVANI, 1998; BORGO, 2007;BUZATTO et al, 2008;KERSTEN et al, 2009;MENINI NETO et al, 2009b;GERALDINO et al, 2010), and if Microgramma is cited as the richest genus, it often shares this position with other genera (ROGALSKI; ZANIN, 2003;BREIER, 2005;MANIA;MONTEIRO, 2010). The other recorded genera (Anemia, Polybotrya and Serpocaulon) often have a low or intermediate richness.…”

ABSTRACT:This study was performed in a remnant of Seasonal Semideciduous Forest at Fazenda Fortaleza de Sant'Anna, in the municipality of Chácara, Minas Gerais, Brazil (22.0129S, 43.8628W), in an area of ca. 1 ha, via monthly expeditions throughout the year 2012. We found 91 species of vascular epiphytes, distributed in 44 genera and 12 families. The richest families were Orchidaceae (35 spp.), Bromeliaceae (18 spp.), Polypodiaceae (10 spp.), Piperaceae (nine spp.) and Araceae (seven spp.). Two species were recorded for the first time in Minas Gerais: Rodriguezia sticta and Stelis oligantha (Orchidaceae). Rhipsalis oblonga (Cactaceae) was recollected in the state after about 100 years without records. Four species are cited in the list of endangered plants in Minas Gerais: Nematanthus crassifolius (Gesneriaceae) and Cattleya bicolor (Orchidaceae) are in the category "Vulnerable" (VU), Nidularium azureum (Bromeliaceae) and Pleurothallis pectinata (Orchidaceae) are "Critically Endangered" (CR). Nidularium azureum is also cited as CR in the Red Book of Brazilian Flora. Most species were classified as characteristic holoepiphytes and anemochory was the most frequent dispersion syndrome.

“…A Serra Negra, localizada na Serra da Mantiqueira, exibe uma fitofisionomia complexa, composta por Campos Rupestres e Florestas Ombrófilas, além de áreas ecotonais. É uma área notavelmente diversa (Menini Neto et al 2009) e conta com o registro, até agora, de pelo menos quatro espécies novas nas famílias Apocynaceae, Lauraceae e Orchidaceae (Batista et al 2008, Assis & Mello-Silva 2010, Matozinhos & Konno 2011 Este trabalho teve por objetivo investigar a diversidade taxonômica das Apocynaceae na Serra Negra, fornecendo descrições detalhadas das espécies, chaves de identificação, e pranchas ilustrativas para o reconhecimento e identificação do grupo.…”

Taxonomic diversity of Apocynaceae at Serra Negra, Minas Gerais State, Brazil). This work aims to present a taxonomic treatment for Apocynaceae from the "Serra Negra", Minas Gerais State, Brazil. Serra Negra is located at Mantiqueira Range, between 21°57'22°S and 43°50'43°55'W, and is characterized by a mosaic of forest formations and rocky fields. Apocynaceae is a widespread family, composed by 3,700 species and 255 genera. In Serra Negra Mountains 12 genera and 24 species were identified. Keys for identification of species are presented with taxonomic descriptions, illustrations and ecological comments.
