Xylopia atlantica, a new and endemic species from the atlantic forest of Bahia, Brazil, is described and illustrated. It is only know from a 150 km long stretch of land from Valença to Uruçuca, in central Bahian coast. The species has leaves up to 41 cm long, bigger than those from any other Brazilian Xylopia. Xylopia atlantica shares with X. decorticans and X. ochrantha cauli and ramiflorous inflorescences. It differs from the former by the non-exfoliating bark, and from the latter by the indument of the monocarps, sparsely yellow-tomentose versus densely golden-tomentose, in X. ochrantha. Although X. atlantica has been collected since relatively long ago, flowering individuals have never been encountered.

Randomly amplified polymorphic DNA (RAPD) markers were used to analyze genetic differentiation among three populations of the endemic Black-cheeked Gnateater (Conopophaga melanops melanops) within a larger pristine reminiscent of the Brazilian Atlantic Forest. Analyses of molecular variance (AMOVA) (phiST = 0.13149, P < 0.0001) and the nonparametric test for homogeneity of the molecular variance (HOMOVA) (B = 0.32337; P = 0.0019) showed a statistically significant genetic divergence among the three Black-cheeked Gnateater populations in a continuous transect of 250 km. Some hypothetic explanations for these results are the sedentary nature of the species and the historical isolation of the populations in refuges during the Pleistocene. The present results suggest that the local populations were naturally differentiated along the entire original range before the recent process of massive deforestation.

ABSTRACT Taxonomic and floristic studies in the state of Rio de Janeiro allowed the rediscovery of Miconia gigantea, an endemic species to the Atlantic Forest, until recently known only from the type specimen, collected over 100 years by A.F.M. Glaziou. We present an amended and detailed description of M. gigantea, providing characteristics of the flowers, fruits and seeds, in addition to illustrations, comments about taxonomic affinities with closely related species, the presently known distribution together with new occurrence records, and the conservation status.

Myrcia sect. Reticulosae comprises ca. 15 Brazilian endemic species distributed mainly in Atlantic Forest, Cerrado (Brazilian savanna) and Campo Rupestre (rocky outcrop vegetation). These species appeared as a cohesive group for the first time in recent phylogenetic hypotheses and their taxonomic revision is currently underway. In this context, this study aims to properly link the names to their respective type materials, presenting necessary lectotypifications and neotypifications, along with nomenclatural notes for nine species. Additionally, two new synonyms are proposed.

ABSTRACT The objective was to present the floristic survey of the bryophytes of the Parque Estadual da Serra do Brigadeiro. It included an evaluation of the species richness, as well as information about the substrate preference of each species and its geographic distributions in Brazil. We found 208 taxa of bryophytes: one hornwort, 88 liverworts and 119 mosses. This richness represents ca. 26% of the bryoflora of Minas Gerais State and ca. 13% of that known for Brazil. Eighteen of the bryophytes species are endemic to Brazil, whereas 19 species are recorded for the first time in Minas Gerais. The bryoflora showed preference for tree bark (30%) and rock (23%) as substrates. Our data show that the Parque Estadual da Serra do Brigadeiro is an important area for the diversity conservation of Brazilian bryophytes and maintenance of endemic species of the country.

AbstractEndemic species are important for biodiversity conservation. Yet, quantifying endemism remains challenging because endemism concepts can be too strict (i.e., pure endemism) or too subjective (i.e., near endemism). We propose a data-driven approach to objectively estimate the proportion of records inside a given the target area (i.e., endemism level) that optimizes the separation of near-endemics from non-endemic species. We apply this approach to the Atlantic Forest tree flora using millions of herbarium records retrieved from multiple sources. We first report an updated checklist of 5044 species for the Atlantic Forest tree flora and then we compare how species-specific endemism levels obtained from herbarium data match species-specific endemism accepted by taxonomists. We show that an endemism level of 90% separates well pure and near-endemic from non-endemic species, which in the Atlantic Forest revealed an overall endemism ratio of 45% for its tree flora. We also found that the diversity of pure and near endemics and of endemics and overall species was congruent in space. Our results for the Atlantic Forest reinforce that pure and near endemic species can be combined to quantify regional endemism and therefore to set conservation priorities taking into account endemic species distribution. We provided general guidelines on how the proposed approach can be used to assess endemism levels of regional biotas in other parts of the world.

A bryophyte checklist of the Ecological Reserve of Gurjaú (08º10’00’’-08º15’00”S; 35º02’30”- 35º05’00”W), a remnant of the Atlantic Forest in the State of Pernambuco, has been compiled. The Reserve covers an area of approximately 1362 ha, including several forest fragments of diverse sizes and stages of conservation. Specimens collected during the years 2000 and 2001, and voucher specimens from the UFP Herbarium at the Federal University of Pernambuco (UFPE) were analyzed. Bryophytes were collected on live and dead trunks, rocks, leaves and soil. The studied bryoflora is composed of 53 species of liverworts, 37 species of mosses and one hornwort. Among the twenty-three registered families, Lejeuneaceae (41 spp.) was the most representative one with the highest generic and specific richness, which confirms its status as predominant in tropical rain forests. Fissidens (7 spp.), Lejeunea and Cheilolejeunea (6 spp.), and Calymperes (4 spp.) were the most representative genera. The studied bryoflora is predominantly composed of species of neotropical distribution, widely spread throughout Brazil. The presence of an endemic species of the Atlantic Forest, Vitalianthus bichlerianus (Pôrto & Grolle) Schust. & Giancotti, and some other exclusively Brazilian species, e.g., Riccardia regnellii (Ängstr.) Hell have been recorded from the site.
