“…With respect to the functional groups, the predominance of true epiphytes has been reported in studies evaluating other forest environments, such as Araucaria forest (Kersten & Silva 2002;Hefler & Faustioni 2004;Kersten & Kunyioshi 2006;Buzatto et al 2008), deciduous forest (Rogalski & Zanin 2003), semideciduous forest (Dettke et al 2008;Bonnet et al 2011) and floodplain forest (Zotz & Schultz 2007). Such predominance has also been reported in other studies of restinga forests (Kersten & Silva 2001;Ribeiro 2009;Mania & Monteiro 2010).…”

Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal woodlands) within the Algodoal-Maiandeua Environmentally Protected Area, located in the municipality of Maracanã, in the state of Pará, Brazil. We sampled five 50 × 50 m plots (three in dry restinga forest and two in floodplain restinga forest), the sampled area therefore totaling 1.25 ha. In the plots sampled, vascular epiphytes were identified and described according to their frequency, abundance, importance value (IV), functional group and vertical distribution (trunk, lower crown or upper crown of the host). For both forest types, we identified 477 individuals belonging to five families, nine genera and 11 species. The most species-rich families were Araceae and Orchidaceae. The species with the highest density, frequency and IV were the secondary hemiepiphytes Philodendron acutatum, Anthurium pentaphyllum and Philodendron muricatum, collectively accounting for 92.1% of all sampled individuals. The true epiphytes predominated. Epiphytic species richness and abundance was greater on the host trunk than in the lower or upper crown. The seasonal climate and structure of the forest favored greater abundance of secondary hemiepiphytes and a higher frequency of epiphytes on the trunks of their hosts.

“…The outstanding representativeness and importance of orchids among tropical and subtropical epiphytes is made explicit by several studies performed in Brazil (Kersten & Silva 2001;Borgo & Silva 2003;Hefler & Faustioni 2004;Staudt et al 2012). Orchid diversity is related to the specificity of many species.…”

“…Orchidaceae is one of the most diverse and abundant families of Atlantic Forest epiphytes (Kersten & Silva 2001;Borgo & Silva 2003;Hefler & Faustioni 2004;Staudt et al 2012). The plants of this family are particularly vulnerable to anthropogenic disturbances, such as habitat loss, predatory collection and exotic species introduction (Martinelli & Moraes 2013;Endres Júnior et al 2015a;Parthibhan et al 2015).…”

Survival and development of reintroduced Cattleya intermedia plants related to abiotic factors and herbivory at the edge and in the interior of a forest fragment in South Brazil

Biotic and abiotic factors, such as luminosity, temperature, air humidity, and herbivory, can affect the establishment of reintroduced plants in natural habitats. This study evaluated the effects of these factors on the survival and growth of Cattleya intermedia plants reintroduced into a forest fragment in South Brazil. Plants of C. intermedia were obtained from in vitro seed germination in asymbiotic culture. Eighty-eight plants were reintroduced at both the forest edge and forest interior. Plants with greater shoot heights and number of leaves and pseudobulbs suffered more damage from herbivores at the edge. There were no significant differences in morphometric parameters between damaged and non-damaged plants in the interior. Tenthecoris bicolor, Helionothrips errans, Ithomiola nepos, Molomea magna and Coleoptera larvae damaged C. intermedia. Luminosity was higher at the edge, while air humidity and temperature were the same in both environments. Herbivory associated with abiotic factors increased plant mortality in the interior, while abiotic factors were determinative of plant survival at the edge. Luminosity is important to the survival of reintroduced epiphytic orchids, and herbivory affects the success of reintroduction.

“…Although some studies on vascular epiphytes have already been conducted on the Araucaria forest this ecosystem has not been extensively studied on its structural or ecological aspects and most published paper are floristic surveys like Dittrich et al (1999) and Hefler & Faustioni (2004) in Municipal Parks, Borgo & Silva (2003) in forest fragments in Curitiba; Kersten and Kuniyoshi (2006) in Iguaçu river basin; Kersten & Rios (2006) in the ecotone between Araucaria forest and deciduous forest in Argentina; and by Kersten & Waechter (2011b) and Bianchi et al (2012), both in an ecotone between Araucaria forest and Atlantic Forest. The only studies that have considered ecological relationships were conducted by Kersten & Silva (2002), who described the population structure of a floodplain forest, and by Kersten et al (2009), who studied the various successional forests seres on the the Iguaçu River floodplain.…”

Edge effect on vascular epiphytes in a subtropical Atlantic Forest

Forest fragmentation affects biological communities by reducing habitat and increasing edges, thus reducing the effective size of the habitable zones. The subtropical atlantic Araucaria forest, typical on the southern Brazil, in some regions has been reduced to less than 1% of its original size lasting only in small isolated fragments. This study aimed to analyse the impact the edge has on vascular epiphyte ensemble in a remnant of Araucaria forest. We surveyed 40 host trees in four transects: one at the edge; and three at 15, 30 and 60 m from the edge. On each host tree we estimated the epiphyte biomass, using four size classes. We compared the transects using Jackknife estimator of absolute species number, diversity indices, non-metric multi-dimensional scaling and multi-response permutation procedure analysis. We recorded 85 epiphytes species. Absolute species richness and diversity were lower at the edge and higher at 60 m in from the edge. Shannon's evenness did not differ significantly among transects and Simpson's evenness values were inconsistent. The vascular epiphyte community under study was significantly altered by the edge.
