“…In the subtropical forests of Brazil, Orchidacae is also cited as the most diverse family (Alves et al 2008;Neto et al 2009;Kersten 2010;Blum et al 2011). However, despite not having the highest species richness in the present study, Orchidacae showed the most generic diversity.…”

“…On the other hand, the family was not even recorded in studies in a terra firme forest in the Brazilian state of Pará (Pos & Sleegers 2010), nor in a savanna in Humaitá, Brazil (Gottsberger & Morawetz 1993). The high occurence of Bromeliaceae in surveys of the epiphytic community is expected for the Atlantic forest, as this is one of the main centers of diversity of this family ), where Bromeliaceae is often cited as the second most diverse (Kersten 2010). In the Brazilian Amazon, the bromeliads are found more frequently in floodplains (baixios), low whitesand forests (campinas), high whitesand forests (campinaranas) and seasonally blackwater-flooded Amazon forests (igapó) (Sousa & Wanderley 2007).…”

“…For Brazil, approximately 460 Araceae species are recognized in 35 genera (Coelho et al 2010). On the other hand, in the Atlantic Forest region in southern and southeastern Brazil, Araceae occupies the sixth position among the most diverse families and on average represents only 4% of the richness in the 62 surveys of epiphytic flora analyzed by Kersten (2010). This family demonstrates incredibly high phenotypic plasticity and ability to grow under adverse conditions (Leimbeck & Balslev 2001;Soares & Jardim-Lima 2005;Coelho et al 2009).…”

10 cm) were sampled. We recorded 3.528 individuals in 13 families, 48 genera and 164 species. Araceae was the most prevalent family with regard to the importance value and stood out in all related parameters, followed by Bromeliaceae, Cyclanthaceae and Orchidaceae. The species with the highest epiphytic importance values were Guzmania lingulata (L.) Mez. and Philodendron linnaei Kunth. The predominant life form was hemiepiphytic. Estimated floristic diversity was 3.2 (H'). The studied epiphytic community was distributed among 727 host plants belonging to 40 families, 123 genera and 324 species. One individual of Guarea convergens T.D. Penn. was the host with the highest richness and abundance of epiphytes. Stems/trunks of host plants were the most colonized segments, and the most favorable habitat for epiphytism was the lowlands, where 84.1% of species and 48.2% of epiphytic specimens were observed.]]>

“…O número de epífitas pode ser comparado ao encontrado em áreas de Floresta Ombrófila Densa (Labiak & Prado 1998, Matos et al 2010) e pode ser explicado pelas condições microclimáticas do PEG, especialmente nas florestas de galerias, onde a umidade relativa do ar é notavelmente mais elevada e constante, quando comparada com outras formações florestais do Parque, condições que providenciam ambientes propícios ao epifitismo (Kersten 2010). Desta forma, com os dados atualmente disponíveis, as samambaias e licófitas representam 42% das epífitas vasculares registradas no Parque.…”

-(Ferns and Lycophytes from Parque Estadual do Guartelá, Paraná State, Brazil). This study deals with the survey of ferns and lycophythes from Parque Estadual do Guartelá, Paraná State, Brazil. The area is characterized by a mosaic of distinct vegetational and geological formations. We found 164 species, distributed in 18 families and 59 genera. It was evident that the vegetational/geological configuration is a determining factor on the habitat preference of the species. Cheilanthes goyazensis and Phlegmariurus badinianus are the first records for the Paraná State, while Lindsaea stricta is the second record for the State. Beside those, Anemia ferruginea and Cyathea myriotricha constitute the third record for the State. We also found eight new records for the Segundo Planalto Paranaense. We conclude that the environmental heterogeneity is directly related to the high floristic richness found in the park.

Este estudo trata do levantamento das espécies de samambaias e licófitas do Parque Estadual do Guartelá, Paraná, área caracterizada por um intricado mosaico de formações vegetacionais e geológicas. Foram encontradas 164 espécies, distribuídas em 18 famílias e 59 gêneros. Ficou evidente que a configuração fitofisionomica/geológica é um fator determinante na preferência habitats das espécies encontradas. Cheilanthes goyazensis e Phlegmariurus badinianus são o primeiro registro para o Estado do Paraná, já Lindsaea stricta é o segundo registro para o Estado, enquanto Anemia ferruginea e Cyathea myriotricha constituem o terceiro registro para o Estado. Além dessas, oito espécies são novos registros para o Segundo Planalto Paranaense. Concluímos que a heterogeneidade ambiental da área esta diretamente relacionada com a elevada riqueza florística local. Palavras-chave: arenito, campos gerais, campo rupestre, canyon

“…Cactaceae family comprises 124 genera and 1,438 species (Hunt et al, 2006) primarily presenting neotropical distribution (Taylor, 1997). The group has countless adaptations to the arid conditions, however, approximately 15% of its representatives, about 220 species, are adapted to the epiphytic behavior in humid tropical and subtropical forests (Bauer, 2006), standing out among the 20 families with the greatest number of epiphytes (Kersten, 2010).…”

Urea concentration on vegetative development and nutrition of Cactaceae epiphytic species

Rhipsalis paradoxa, Rhipsalis baccifera and Hatiora salicornioides are epiphytic cacti from the Atlantic Forest. They have a great ornamental potential due to the exotic characteristic of their joints (stems segments). The study aimed to evaluate the growth and development of roots and shoots as well as macronutrient and micronutrient contents in the joints of these species fertilized with different concentrations of urea as a nitrogen source. The study also analyzed the importance of the root system on nitrogen absorption. Plants were weekly irrigated with modified Hoagland & Arnon solutions with 0, 16.7, 33.3, 49.9 or 66.6 mM N applied as urea. After 180 days of cultivation, plants were separated into joints and roots for biometric and biomass measures, as well as macronutrient and micronutrient analysis of joints. The experimental design was randomized blocks, with five treatments, four blocks and five plants per plot, for each species. Data were submitted to analyses of variance and regression. R. baccifera showed the highest plant length and number of joints in 29.94 and 40.82 mM N, respectively, H. salicornioides showed the highest length and number of joints in 48.29 and 45.68 mM N respectively. For R. paradoxa, the highest length was in 66.6 mM N. The lowest values for plant length and number of joints were observed in the absence of N, for all species. High nitrogen concentrations in the solution increased the N concentration in joints of R. baccifera, R. paradoxa and H. salicornioides by 24, 19 and 13 g N/kg dry mass, respectively. The roots of epiphytic cacti, besides the function of fixing the plant on substrate (phorophyte), are functional for nutrient absorption, and the best results were obtained in 30.05 to 66.60 mM N in the nutrient solution.
