title: Flora of Espírito Santo: Psidium (Myrtaceae)

description: Abstract This study presents a floristic-taxonomic treatment of Psidium in the state of Espírito Santo, and is a result of fieldwork combined with analyses of herbarium specimens. Fourteen species of the genus were recognized in Espírito Santo state (P. brownianum, P. cattleianum, P. cauliflorum, P. guajava, P. guineense, P. longipetiolatum, P. myrtoides, P. oblongatum, P. oligospermum, P. ovale, P. rhombeum, P. rufum P. sartorianum, and Psidium sp.), accounting for about 34% of the species richness estimated for the genus in the Atlantic Rainforest biome. The species occur predominantly in lowland forests up to 700 meters above sea level. These areas are highly threatened due to urbanization of coastal areas and agricultural expansion in the state Espírito Santo. Therefore, the conservation of Psidium species in this state requires the creation of more lowland protected areas.

title: Ferns and Lycophytes from fragments of semideciduous forest in central Espírito Santo, Brazil

description: Abstract This study presents a checklist of lycophytes and ferns from secondary semideciduous forests in São João de Petrópolis, Santa Teresa, Espírito Santo, Brazil. We recorded 37 species (four lycophytes and 33 ferns) belonging to nine families and 17 genera. Selaginella is the only genus representing lycophytes whereas Adiantum, Anemia and Asplenium are the main representative genera for ferns. Most species are lithophytes (48.6%) or terrestrial (21.6%). Epiphytes are scarce (8.2%), and we did not record any arborescent, hemiepiphyte or scandent species. Climate seasonality, reduced size of forest fragments, and disturbance history may explain the low richness in the site. We recorded the occurrence of a regionally threatened fern species, namely, Asplenium austrobrasiliense, and revealed the first record of Asplenium otites in Espírito Santo. This demonstrates the biological relevance of semideciduous forest remnants in Espírito Santo and reinforces arguments for their effective protection.

title: An illustrated guide of ferns and lycophytes from Carambeí, PR, Brazil

description: Abstract We present a list of species of ferns and lycophytes from Carambeí, a municipality located in Paraná state, southern Brazil. This area, locally known as “Campos Gerais”, presents an intricate mosaic of forests and savannah with several canyons and humid valleys that harbors a rich and unique vegetation in Southern Brazil. In total, we found 129 species (119 ferns and 10 lycophytes), distributed in 18 families and 59 genera, and 20% (26 spp.) of which are endemic to Brazil. The most expressive families were Polypodiaceae (19 spp.), Pteridaceae (18 spp.) and Thelypteridaceae (15 spp.). The most representative genera were Asplenium (8 spp. - 6.2%) and Amauropelta (8 spp - 6.2%). Terrestrial herbs, epiphytes and lithophytes are the most common guild of life forms, successively. The richest environments were woody forest (61% of the species) and herbaceous-shrubby (12%). Arachniodes denticulata, Phlegmariurus flexibilis and P. Heterocarpon are the second record in the “Campos Gerais” region. We also provide photographic plates with diagnostic characters for most of the species.

title: Checklist of ferns and lycophytes from the highlands of Pico Paraná State Park, Paraná, Brazil

description: Abstract We present a checklist for the ferns and lycophytes from Pico Paraná State Park, in Southern Brazil. The Park is entirely located at the Serra do Mar mountains, and represents an important remnant of the Atlantic Rain Forest with altitude achieving 1,887 m. In this locality is the Pico Paraná, the highest mountain in Southern Brazil. This study was focused on the altitudes above 1,000 m, which are mainly represented by dwarf forests and altitudinal fields. A total of 142 species were recorded, three of them (Ceradenia maackii, Diplazium tamandarei, and Stenogrammitis wittigiana) are only found in the park in Southern Brazil. Besides of the checklist of the species, we highlight some important aspects related to endangered species, geographic distribution, and life forms. The high level of endemism, the presence of endangered species, and the phylogenetic diversity as represented by distinct families of ferns and lycophytes show the biogeographic importance of this area for the conservation of these groups of plants.

title: Cerrados in Argentina? Structure, diversity and biogeography of the woody component of a savanna in the Misiones Province

description: Abstract The Teyú Cuaré field, in Misiones province, Argentina, has been renowned for its flora and physiognomy, which led researchers to indicate that it could be a relict of Cerrado biome. We analyzed the floristic structure of the woody component of a savanna community in this site, and discussed the processes that could contribute to the permanence of this vegetation type over time. Perimeter and height of all woody individuals ≥ 10 cm of perimeter at soil height were collected in 12 square plots (400 m2 each one). We found 15 families and 17 species in our site and compared the woody flora surveyed at this site with the flora of other Cerrado áreas from Brazil and Paraguay. Leptolobium elegans had the highest importance value. The woody flora of the área is closely related to the Cerrado areas from Paraná state in Brazil and Canindeyú and Amambay in Paraguay. This site probably reflects old open physiognomies which were predominant in Misiones and Southern of Brazil in the late Pleistocene and middle Holocene. We inferred that the permanence of open physiognomies at Teyú Cuaré is probably related to mechanisms that act at different levels, such as geological, edaphic, anthropic, and fire disturbance.
