25. Sisters of the Atlantic: slavery and urban space in Rio de Janeiro and Havana (1763-1844) / Irmãs do Atlântico. Escravidão e espaço urbano no Rio de Janeiro e Havana (1763-1844)
A presente tese de doutorado pretende analisar as razões que levaram Rio de Janeiro e Havana a se constituírem como as maiores cidades escravistas das Américas. O recorte inicial da pesquisa é o ano de 1763, quando as duas cidades transformaram-se em localidades-chave nos Impérios Ibéricos graças ao reordenamento das possessões europeias no Novo Mund

26. Fine-scale spatial genetic structure of Dalbergia nigra (Fabaceae), a threatened and endemic tree of the Brazilian Atlantic Forest
The Atlantic Forest is one of the most diverse ecosystems in the world and considered a hotspot of biodiversity conservation. Dalbergia nigra (Fabaceae) is a tree endemic to the Brazilian Atlantic Forest, and has become threatened due to overexploitation of its valuable timber. In the present study, we analyzed the genetic diversity and fine-scale spatial ge

27. Two new land planarian species (Platyhelminthes: Tricladida) from the Brazilian Atlantic Forest
The Brazilian Atlantic Forest harbors the world's richest areas of land planarians (Platyhelminthes: Tricladida). Nevertheless, the number of undiscovered species from this biological unit remains seemingly high. Herein we describe Geoplana piriana Almeida & Carbayo, sp. nov. from the state of Rio de Janeiro, and Geoplana tingauna Kishimoto & Carbayo, sp. no

28. Prokaryotic communities of acidic peatlands from the southern Brazilian Atlantic Forest
The acidic peatlands of southern Brazil are ecosystems essential for the maintenance of the Atlantic Forest, one of the 25 hot-spots of biodiversity in the world. In this work, we investigated the composition of prokaryotic communities in four histosols of three acidic peatland regions by constructing small-subunit (SSU) rRNA gene libraries and sequencing. S

29. Evidence that the Ceratobasidium-like white-thread blight and black rot fungal pathogens from persimmon and tea crops in the Brazilian Atlantic Forest agroecosystem are two distinct phylospecies
The white-thread blight and black rot (WTBR) caused by basidiomycetous fungi of the genus Ceratobasidium is emerging as an important plant disease in Brazil, particularly for crop species in the Ericales such as persimmon (Diospyros kaki) and tea (Camellia sinensis). However, the species identity of the fungal pathogen associated with either of these hosts i

30. Distribuição e uso de habitat por peixes recifais e sua relação com a complexidade ambiental no arquipélago Fernando de Noronha, Nordeste do Brasil.
Reef environments are amongst the most diverse ecosystems in the world. Many studies attempting to explain the mechanisms which influence reef fish distribution and the factors responsible for high species diversity in these environments were accomplished in the last decades, but much controversy still exists and more information is, therefore, necessary. Th

31. Espécies invasoras em sítios de restauração florestal de floresta estacional
Exotic invasive species are the second greatest cause of biodiversity loss in the world. In forest restoration, these invaders can cause serious problems, like the suppression or exclusion of plants through competition and changes in the environment. Among these species, tropical invasive grasses are responsible for heavy costs and contribute to several setb

32. In vitro cytotoxic effects of Brazilian plant extracts on squamous cell carcinoma of the oral cavity
Squamous cell carcinoma (SCC) is the most prevalent cancer of the oral cavity and the fifth most prevalent of all malignancies in males. Many researchers have attempted to develop new treatments that will improve the prognosis of SCC patients. Over 20% of the world's biodiversity is located within the Brazilian forests, but little is known about the chemical

34. Sand flies of Nicaragua: a checklist and reports of new collections
Sand flies within the genus Lutzomyia serve as the vectors for all species of the protozoan parasite Leishmania in the New World. In this paper, we present a summary of the 29 species of Lutzomyia and one of Brumptomyia previously reported for Nicaragua and report results of our recent collections of 565 sand flies at eight localities in the country from 200

35. Molecular identification, phylogeny and geographic distribution of Brazilian mangrove oysters (Crassostrea)
Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring along the Brazilian coast, and phylogenetically relate these to other Crassostrea from different parts of the

36. Myrtaceae Juss. no Alto Quiriri, Garuva, Santa Catarina, Brasil / Myrtaceae juss in the High Quiriri, Garuva, Santa Catarina, Brazil
Myrtaceae, consisting of woody plants, is one of the ten richest families in number of species among angiosperms in the world, as well as in Brazil, especially in the Atlantic Forest, also known as Floresta Ombrófila Densa and its subdivisions. When it comes to plants as shrubs or trees, it is expected to have a high representation in phytosociological stud
