Introduction: Local environmental filters have shown the influence on the bryophyte diversity and structure communities, but there are limited studies that analyze how biotic relationships filters influence these communities. Objective: To evaluate whether the influence of fern Asplenium auritum cover determine changes in species richness and composition of bryophyte communities, in a semideciduous remnant forest, Minas Gerais, Brazil. Methods: We selected one transect of 300 m in each of six areas where Asplenium auritum was present. In all transect we estimated plant cover in 39 10 × 10 cm plots randomly distributed. We compare the estimated species richness and composition of bryophyte between fern coverage levels. Results: We found 60 species in 35 genera and 23 families. Weft and mat were the most represented life-forms. Fern cover had no significant effect on bryophyte species richness and composition. Conclusions: Bryophyte cover appears to improve fern development and promote the coexistence of several bryophyte species. Bryophyte cover probably predicts variations in species richness and drives the species assemblage in this community.

Reference Ecosystem

The evaluation of the forest restoration scenario is of great importance, with floristic composition and diversity being among the most used ecological variables as indicators. This research aimed to identify the current situation, in terms of species composition and diversity, of two riparian forests under restoration based on a reference ecosystem, the Brazilian Atlantic Forest. Twenty permanent plots (250 m²) were located in areas under restoration process (AR1 and AR2) and in a forest fragment of the region which served as a reference ecosystem (ER). We sampled, identified and classified all tree individuals with CBH ≥ 15.0 cm in each plot. Aiming to understand species richness and diversity, besides the traditional indexes (Shannon and Simpson), we also estimated the effective numbers of Hill’s diversity (qD = 0, 1 and 2) considering rarefaction (P ≤ 0.05); and to detect floristic similarities among the study areas we performed a Principal Coordinate Analysis (PCoA). We found dissimilarity among ARs and ER, and the presence of exotic species, indicating that, as recommended, such reference should have been taken into account during the planning of the restoration action. Considering the effective numbers of species (qD) we found differences between the areas, species richness and diversity was higher in ER > AR2 > AR1. We also show that among the restoration areas, with the same age and submitted to the same conditions, AR2 has features that allow us to conclude that this area has a bigger chance of success in the restoration process. However, aiming environmental sustainability, we suggest that some corrective actions should be taken in order to favour the reestablishment of ecological processes in these areas.

Taxonomic Approach

Abstract Orchidaceae is a megadiverse botanical family in Brazil, particularly in the Atlantic Forest where it is a priority group for conservation. Parque Nacional do Itatiaia (PARNA Itatiaia) was the first conservation unit established in Brazil, and represents a large and mature remnant of Atlantic Forest. Updated data on richness, distribution and conservation of the Neotropical and ornamental subtribe Laeliinae in the park recently disclosed the occurrence of presumed locally extinct species, but without a taxonomic approach. Thus, we present a comprehensive taxonomic treatment of Laeliinae in the PARNA Itatiaia. The subtribe is represented by six genera and 33 species, which corresponds to about 15% of the orchid flora of PARNA Itatiaia. Epidendrum is the richest genus, with 20 species, followed by Cattleya (6 spp.) and Prosthechea (4 spp.). Species of Laeliinae grow in shady and humid habitats, especially near rivers, at elevations ranging 750-1,200 m, with species richness decreasing with elevation. Several species form small populations (commonly < 10 individuals), which are in need of prompt conservation actions to avoid local extinction. Samples of Laeliinae from PARNA Itatiaia in collections of consulted herbaria were found to be scarce. Variable morphological characteristics, mainly of the lip, distinguishe species of Laeliinae.

A New Species

One of the most important families in terms of species richness in the Atlantic Forest and other lowland tropical forests is Annonaceae (Leitão-Filho 1987, Ter Steege et al. 2000), among which Guatteria is one of the largest genera with 211 species (Maas et al. 2011); it is also one of the most diverse genera of Neotropical trees. Erkens et al. (2007) stated that an updated revision is needed, and Lobão et al. (2012) revised the species of the Brazilian Atlantic Forest.
