“…The phylogeographic results of Vriesea oligantha showed a remarkable congruence between the structure of different populations and the bioregionalization proposed by Colli-Silva et al (2019), based on patterns of plant endemism in the Espinhaço Range. Similar biogeographic patterns were also pointed out by several other studies using floristic and faunistic composition and endemicity indexes (e.g., Bitencourt & Rapini, 2013;Bünger, Stehmann & Oliveira-Filho, 2014;Campos, Freire Moro, Funk & Roque, 2019;Chaves et al, 2015) and phylogenetic histories (e.g., Chaves et al, 2019;Ribeiro et al, 2014). Taken together, these studies suggest that particular drivers are leading the evolutionary history, community assembling, and physiognomy patterns of distinct areas in the Espinhaço Range (Zappi, Moro, Meagher, & Nic Lughadha, 2017).…”

AimThe exceptional species-richness associated with mountains worldwide is linked to the fragmented topography of these areas, responsible for constantly isolating populations during periods of climatic fluctuations. Consequently, endemism and spatial turnover in mountains are very high and few species are widespread among entire mountain ranges, precluding population-level studies that help understanding how macroevolutionary patterns were shaped. Here, we used the bromeliad Vriesea oligantha, a species endemic to, but widespread in, one of the most species-rich ancient montane areas in the globe, the Espinhaco Range, to test how environmental changes over time may have acted on the evolutionary history of this taxon, contributing to understanding how montane macroevolutionary patterns were shaped. Through analyses of plastidial and nuclear DNA of V. oligantha, we dated its origin and intraspecific diversification, and estimated the genetic diversity, structure and migration rates among populations. Using climatic and geographic variables, we modeled suitable areas for the present and the past, estimating corridors between isolated populations. We also used demographic analyses to estimate ancient population dynamics of V. oligantha. Finally, we tested whether climatic variables or geographical distance explain the observed population structure. The origin and intraspecific diversification of V. oligantha are related to early climatic oscillations during the Plio-Pleistocene. This species has a high population structure due to its low pollen and seed dispersibility. The analysis of species distribution modeling estimated corridors between populations in the past, whereas the structure of V. oligantha results from both models of isolation by distance and isolation by environment. The phylogeographic patterns of Vriesea oligantha reflect previously recognized spatial and temporal macroevolutionary patterns in the Espinhaco Range, providing insights into how microevolutionary processes may have given rise to this astonishing mountain biodiversity.

“…These localities are within the Espinhaço Mountain Range, which is dominated by “Campos Rupestres” (montane savannah/rocky fields) vegetation (Melo 2000, São-Pedro and Feio 2011) and recognized as an important biodiversity and endemism center (Harley and Simmons 1986, Melo 2000, Rapini et al 2008, Bünger et al 2014). Selaginella mucronata was collected in Castelo, Parque Estadual do Forno Grande, a locality that has highland remnants of the rich, biodiverse Atlantic Rainforest vegetation in the state of Espírito Santo, southeastern Brazil (Meirelles and Goldenberg 2012, Silva-Soares and Scherrer 2013).…”

We describe seven new species of Selaginella subg. Stachygynandrum (Selaginella alstonii, Selaginella blepharodella, Selaginella crinita, Selaginella mucronata, Selaginella mucugensis, Selaginella saltuicola, and Selaginella sematophylla) from Brazil and discuss their possible affinities and conservation status. Scanning electron micrographs of stem sections, leaves, and spores are provided to illustrate the new taxa. In Selaginella alstonii and Selaginella saltuicola vegetative growth from strobilus tips is reported and discussed. Four of the new species are from the Espinhaço Mountain Range associated with Campos Rupestres (montane savannah/rocky fields) vegetation. Three of these (i.e., Selaginella blepharodella, Selaginella crinita, and Selaginella mucugensis) were collected in the northern part of the range in Chapada Diamantina, state of Bahia, while Selaginella alstonii is from the southern part of the range in the state of Minas Gerais. Selaginella mucronata is found in Atlantic Rainforest vegetation in the state of Espírito Santo, whereas Selaginella saltuicola inhabits Cerrado (tropical savannah) vegetation in the state of Mato Grosso. Selaginella sematophylla is the most widely distributed of the new species and was collected in Espírito Santo, Minas Gerais, and Rio de Janeiro states in Campos Rupestres and Atlantic Rainforest vegetation. Selaginella alstonii occurs in rocky caves, Selaginella blepharodella, Selaginella crinita, Selaginella mucugensis, and Selaginella sematophylla seem adapted to seasonally dry places, living on sandy or humid soils, Selaginella mucronata occupies humid, forest understory, and Selaginella saltuicola is adapted to wet places associated with rocks or logs in waterfalls. Of the seven new species, six are considered local endemics (except for Selaginella sematophylla) because of their restricted currently known distributions to one or two localities within a single state in Brazil. Additionally, we propose new synonymy for Selaginella palmiformis (syn. = Selaginella bahiensis subsp. manausensis, ≡ Selaginella manausensis) and Selaginella vestiens (syn. = Selaginella fragillima); the last species is endemic to Brazil, recorded in the states of Goiás and Minas Gerais. Finally, based on literature discussed and this study, we conclude that the number of well-documented Brazilian Selaginella species is 61, of which 58 are native and three introduced and naturalized. These statistics are likely to change with further work on Selaginella from Brazil.

“…Although the Espinhaço Range has been the focus of studies of naturalists over the last two centuries, basic information about the small mammal's species richness and composition is still scarce (Lessa et al 2008, Braga et al 2016. The Central Espinhaço in Minas Gerais state is within the Cerrado (savanna), and the predominant vegetation type consists of "campos rupestres" (rock grassland), although the vegetation mosaic also includes semi-deciduous and dwarf forests (Mendonça-Filho 2005, Bünger et al 2014). This complex biome holds the third highest mammal's diversity of Brazil (251 species) with many endemic and/or patchily distributed species (Paglia et al 2012).…”

Survey of Small Mammals (Rodentia and Didelphimorphia) in a Cerrado Reserve: Central Espinhaço Mountain Range, Brazil

Despite its high diversity, small mammals within the Cerrado (savanna) at the Central Espinhaço Range are poorly known, and precise information regarding the geographical distribution of all species is still scarce. Here we present data on terrestrial small-sized mammals (Didelphimorphia and Rodentia) from Parque Estadual do Rio Preto (PERP), a protected area in the Central Espinhaço and compare the species composition of this area with other protected areas in the Espinhaço Range. Over the course of 10,616 trap-nights, there were 700 captures of 245 individuals, being eight species from de order Didelphimorphia and eight from Rodentia, with an overall capture rate of 6.6%. We report both, Gracilinanus agilis and G. microtarsus, occurring in sympatry and the occurrence of Thalpomys lasiotis, known to be endemic to the Cerrado biome. We observed that the species composition of the Central Espinhaço contains a set of species different from those found in Southern Espinhaço (Serra de Ouro Branco). This may be most the result of vegetal physiognomies among the inventoried areas and less clearly the result of geographic distance between them. Considering that the conservation strategies focus basically on the richness and the occurrence of endemic species, we here emphasize the need for further research efforts in order to improve our knowledge about the Espinhaço fauna.
