We have modeled the ecological niche for 12 plant species belonging to the genusDavilla(Dilleniaceae) which occur in the Atlantic Forest of Brazil. This group includes endemic species lianas threatened by extinction and is therefore a useful indicator for forest areas requiring conservation. The aims are to compare the distribution and richness of species within the protected areas, assessing the degree of protection and gap analysis of reserves for this group. We used the Maxent algorithm with environmental and occurrence data, and produced geographic distribution maps. The results show that high species richness occurs in forest and coastal forest of Espírito Santo to Bahia states. The endemic species compriseD. flexuosa, D. macrocarpa, D. flexuosa, D. grandifolia, andD. sessilifolia. In the Atlantic Forest of southeastern Brazil, the following endemic species occur:D. tintinnabulataandD. glaziovii, with this latter species being included in the “red list” due habitat loss and predatory extractivism. The indicators of species richness in the coastal region of Bahia correspond with floristic inventories that point to this area having a high biodiversity. Although this region has several protected areas, there are gaps in reserves, which, combined with anthropogenic threats and fragmentation, have caused several problems for biodiversity.

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.

Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.

The objectives of this study were to identify anthophilous butterflies on psychophilous flowers of four Asteraceae species in an Atlantic Forest fragment in Viçosa, Minas Gerais State, Southeastern Brazil, and to determine whether there are species in common with other lepidopteran inventories of the Southeastern and Midwestern regions of Brazil. It is the first inventory of anthophilous butterflies of a semideciduous forest fragment in Zona da Mata, State of Minas Gerais. A total of 108 species were recorded, representing the fourth largest lepidopteran survey in this State. The results demonstrated that Asteraceae species may be important tools for monitoring anthophilous butterflies. The similarity with other inventories ranged from 1 to 92.55%. Fifteen species were reported for the first time in the State of Minas Gerais, and among them, Melanis alena and Thisbe irenea were observed in this study only.

Abstract In recent decades, current knowledge about fish from Neotropical streams has greatly increased, but is still deficient. Here we present an identification key for fishes from coastal freshwater streams from a large conservation area of Atlantic rainforest of southeastern Brazil, including 39 species. Considering that most of these species (61.2%) are endemic to the coastal streams, this identification key will be useful not only for the species recognition of the sampled area, but also for the surrounding coastal region.

Polypodiaceae is notable for being one of the richest, most diverse, and abundant groups of ferns in tropical and subtropical forests. Currently, 65 genera and approximately 1652 species are recognized in the family. Pleopeltis is a monophyletic genus and comprises approximately 90 species, most of which are exclusive to the Neotropics. The aim of this scientific contribution is a taxonomic treatment of the Pleopeltis species occurring in Brazil. It has been based on the morphological data of specimens from Brazilian and foreign herbaria, as well as on observations and collections made in the field. Eighteen species are recognized in Brazil and occur in all Brazilian biomes, notably the Atlantic Forest (16 spp.). At least one species occurs in all Brazilian states, and the states of Espírito Santo and Minas Gerais (southeastern Brazil) are the richest (11 spp. each). According to the Brazilian Flora Red List, three species are officially threatened, P. alborufula and P. monoides are endangered, and P. trindadensis is critically endangered; however, we suggest including two more species in the official list: P. aturensis and P. stolzei. The taxonomic treatment includes a genus description, identification key to the species, synonyms, species description, distribution maps, illustrations, list of specimens studied, taxonomic comments, and information on habitat and distribution.

This study reports 2 years of the population dynamics and reproduction of a small mammal community using the removal method. The study was conducted in a rural area of the Atlantic Forest, in Sumidouro, Rio de Janeiro State, Brazil. The population sizes, age structure and reproduction were studied for the four most common species in the study area. The overall diversity was 1.67 and ranged between 0.8 to 1.67. The species richness was 13 considering the whole study. The most abundant species were the rodents Nectomys squamipes (n = 133), Akodon cursor (n = 74), Oligoryzomys nigripes (n = 25) and the marsupials Didelphis aurita (n = 58) and Philander frenatus (n = 50). Seven other rodents were captured once: Necromys lasiurus, Akodon montensis, Sooretamys angouya, Oecomys catherine, Oxymycterus judex, Euryzygomatomys spinosus and Trinomys iheringi. There were higher peaks for diversity and species richness during the winter (dry) months, probably due to higher food availability. The marsupials had a seasonal reproduction with highest population sizes at the end of the rainy seasons. Nectomys squamipes reproduced mostly during rainy periods. Akodon cursor reproduced predominantly in the winter with the highest population peaks occurring during this season. The analysis of the population dynamics of the rodent species indicated that no species behaved as an agricultural pest, probably due to the heterogeneous landscape of high rotativity of vegetable cultivation. Rodent populations were more susceptible to the removal procedure than marsupial ones.
