“…The altitude can justify these results, whereas that richest areas in vascular epiphytes have been recorded in elevations between 1,000 and 2,000 m in several studies (Madison 1977;Gentry & Dodson 1987;Benzing 1990;Küper et al 2004;Krömer et al 2005; The richest families are according to the patterns found in the Neotropical Region (NR) (Mendieta-Leiva et al 2020) and the Atlantic Forest (AF) (Ramos et al 2019), in which Orchidaceae and Bromeliaceae are the richest. Polypodiaceae is the third richest family and often occupy such rank in small scales, although Araceae, the third in AF and NR, is the fourth richest family in the SR (Hietz & Hietz-Seifert 1995;Wolf & Alejandro 2003;Obermüller et al 2012;Marcusso & Monteiro 2016;Furtado & Menini Neto 2018a;Araújo et al 2019;Barbosa et al 2019), which was corroborated in the present study. These four families together represent 70% of the recorded species in the SR.…”

“…Thus, in addition to watercourses, the RPPNABV is above 1,000 m a.s.l. and is influenced by orographic rainfalls, and can therefore offer favorable conditions for species demanding a moister environment (Bonnet et al 2010;Marcusso & Monteiro 2016), as the species occurring in the rainforest, such as Asplenium mourai, Cirrhaea dependens, Cochlidium punctatum, Elaphoglossum glaziovii, Epidendrum chlorinum, Hymenophyllum caudiculatum, Lellingeria apiculata, Melpomene pilosissima, Moranopteris achilleifolia, Phlegmariurus biformis, P. fontinaloides, Vriesea bituminosa, V. longicaulis, and V. penduliflora. (BFG 2018) and are not present in the RBRG, which has lower elevations between ~500 and 700 m a.s.l.…”

Vascular epiphytes of the Serra do Relógio: the surprising richness of the seasonal forests in the mountains of Minas Gerais, Southeastern Brazil

Studies conducted on vascular epiphytes in Minas Gerais have revealed high richness in the seasonal semi-deciduous forests (SSF) in comparison with those of other Brazilian states. This study aimed to present a vascular epiphyte checklist of the Serra do Relógio (SR) in the Atlantic Forest of Minas Gerais, in order to analyze the similarity between two areas in different altitudes, as well as to discuss the high richness recorded for this synusia in the SSFs of this state. The survey was performed in two conservation units (CUs) apart from each other approximately 6 km and with elevations varying between ~500 and 1,434 m. The data were obtained from published articles and fieldwork performed between the years 2016 and 2019. We recorded 158 species distributed in 76 genera and 22 families. This richness is greater than those found in some ombrophilous forests, which was an unexpected result due to the high moisture of this phytophysionomy. Although approximately 66% of the species found in the SR are anemochoric and the compared CUs are geographically close, the similarity was only 22%, suggesting that the difference in altitude between the areas and the history of use can impose filters that influence the floristic composition of each one area. These results highlight the importance of preserving the forest remnants in Brazil and creating and maintain CUs to protect them.

“…The predominance of holoepiphyte characteristics is an expected pattern (Freitas et al 2016;Zotz 2016). On the other hand, the great number of facultative holoepiphytes recorded is outstanding (38.1 % overall) when compared with some sites of the Atlantic Forest (Bonnet et al 2011;Padilha et al 2015;Couto et al 2016;Marcusso & Monteiro 2016;Rolim et al 2016). This different pattern could be explained by the abundance of rock outcrops in the studied area (Biral & Lombardi 2012;Perleberg et al 2013;Couto et al 2016).…”

Plants in the clouds: vascular epiphytes of Pedra Azul, a mountain top in Espírito Santo, Southeastern Brazil

Cloud forests usually occur at high-altitude sites of the Atlantic Forest in eastern Brazil, albeit scattered and fragmented along the mountain tops. In this habitat, the vegetation occurs at low-temperature conditions and is usually provided by additional water sources that arise due to the horizontal precipitation of the frequent fogs. Together with the more considerable air movement and higher luminosity, these factors are conditioning for singular floras at high elevations, mainly the vascular epiphytes, which are macro and microclimate dependent. In the mountains range at the center of the Espírito Santo state, Southeastern Brazil, some mountain tops such as Pedra Azul (PA) hold these environmental features. Here, we aimed to present the first checklist of vascular epiphytes in the Pedra Azul State Park and surroundings based on fieldwork and herbarium specimens. The checklist comprises 152 species, 65 genera, and 17 families, the main families being Orchidaceae, Bromeliaceae, and Polypodiaceae, with the main genera represented by Vriesea, Acianthera, and Peperomia. The holoepiphytes were the main category among the epiphytes, although an unusually high number of facultative epiphytes were recorded. Asplenium theciferum and Octomeria cucullata are recorded in Espírito Santo for the first time, and we confirmed the occurrence of Rhipsalis cereuscula in the state. Overall, the richness recorded in PA is amongst the highest of the Atlantic Forest cloud forests. Six species are threatened at the national level and 32 at the state level. These results support the importance of the protected area for conserving the flora; however, several species - including threatened - were only recorded in the surroundings, demonstrating that the buffer zone of the Pedra Azul State Park must be included in the management plans.

Premise Epiphytes have commensal relationships with their host trees. Besides the influence of tree traits, little has been discussed concerning the ecology of epiphytes in disturbed habitats (e.g., pasture). We herein tested whether the occurrences of pasture and forest specialist epiphytes in pastures are affected differently by tree traits. We hypothesized that (H1) the richness and abundance of generalist epiphytes would be positively associated with area availability; (H2) the richness and abundance of forest epiphyte species would be associated both with (H2.a) area availability and (H2.b) tree traits related to higher seed adherence, and/or (H2.c) less severe habitat (e.g., high humidity and more shade). Methods We sampled 9567 epiphyte individuals from 16 species on 759 scattered remnant trees. The epiphyte species were divided into two ecological groups: forest specialists and pasture specialists. We evaluated four host tree traits: two related to tree size (crown area and trunk diameter) and two related to habitat type (crown leaf density and bark rugosity). Results The richness and abundance of both pasture and forest specialists were positively related with tree size. However, the abundance of pasture specialists was negatively related with crown leaf density, whereas richness of forest epiphytes was positively related with bark rugosity. Conclusions Large scattered trees tend to present higher richness and abundance of both pasture and forest specialist epiphytes compared to the smaller trees. However, high crown leaf density limits abundance of pasture specialist epiphytes, whereas rugose bark increases the richness of forest epiphytes.
