13. Description of a new Brazilian species of Mycodrosophila (Diptera, Drosophilidae) with emphasis on the morphology of phallic sclerites
ABSTRACT Mycodrosophila is a cosmopolitan genus of Drosophilidae that comprises approximately 130 species with mycophagous habitats. In this study, we described a new species of Mycodrosophila based on morphological traits and included details of the male terminalia. The holotype is from Eugênio Lefévre, locality in Campos do Jordão municipality, SP, Braz

14. Description of a second known Liotyphlops caissara specimen (Serpentes: Anomalepididae)
Abstract: We recorded a second specimen of the poorly known insular blind snake Liotyphlops caissara. This new specimen expands the morphological variation of the number of dorsal scales in the genus Liotyphlops to 296 (vs. 304 in L. wilderi) and, considering the fact that the holotype of this species was destroyed, the present specimen represents the only a

15. Distribution extension of Phimophis guerini (Serpentes: Dipsadidae: Xenodontinae) in the Brazilian Amazon
ABSTRACT Phimophis guerini Duméril, Bibron & Duméril, 1854 is a Xenodontinae snake distributed in Argentina, Brazil and Paraguay. In Brazil, the species is broadly distributed, occurring mainly in open areas of the Cerrado, but also in the Amazon, Atlantic forest and Caatinga. We provide a new record for this species from the municipality of Santarém in t

16. Field Description and Identification of Diagnostic Qualifiers for Urban Soils in Brazil
ABSTRACT Human activities often alter soils found in urban areas. These alterations affect their environmental functions and potential for use. However, soils from urban areas in Brazil have not been surveyed and identified, which can pose a technical problem for the development of the city. Considering the importance of urban environments and their soils, t

17. Pedogenesis in a topo-climosequence in the Agreste region of Pernambuco
RESUMO O Planalto da Borborema é caracterizado pelos diferentes estágios de evolução do relevo, modificando o clima e a vegetação, sendo observadas florestas tropicais, (brejos de altitude), circundado por caatinga. O objetivo deste trabalho foi caracterizar os solos de uma topoclimossequência no agreste pernambucano, avaliandoa influência do relevo

18. Phylogeny of the Augochlora clade with the description of four new species (Hymenoptera, Apoidea)
ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social,

19. Edaphic and Topographic Factors and their Relationship with Dendrometric Variation of Pinus Taeda L. in a High Altitude Subtropical Climate
ABSTRACT The study of the relationships between the yield potential of forest stands and the conditions offered for plant development is fundamental for the adequate management of the forest when aiming at sustainable high yields. However, these relations are not clear, especially in commercial forests, on rugged terrain where relationships between the lands

20. Cytogenetics of two hylid frogs from Brazilian Cerrado
Abstract Cytogenetic data can be useful for taxonomic and phylogenetic studies, as well as to provide information about chromosome evolution. Therefore, it may help design conservation priorities for some threatened species, such as anurans. Herein, we describe the karyotypes of Scinax constrictus and Ololygon centralis, native endemic species from the Brazi

21. Morphological, Chemical and Molecular Characterization of ‘Old olive’ (Olea europaea L.) from Montenegro
ABSTRACT Thousands of years of tradition of olive cultivation in Montenegro is witnessed with the ‘Old olive’ estimated to be more than 2000 years old. ‘Old olive’ draws attention to its genetic potential and the relation to the closest grown olive cultivars. Therefore, the aim of this paper was to give the basic description of ‘Old olive’ (throu

22. Propagación del banano: técnicas tradicionales, nuevas tecnologías e innovaciones
Abstract The different propagation systems for the banana: conventional or by tissue culture are reviewed. Conventional propagation, mainly using suckers, whole rhizomes or bits are still in use for familiar plantings or in farms for local markets in many tropical countries, while vitroplants are the rule in modern commercial banana cultivation. After exami

23. Mycological Diversity Description I
ABSTRACT Here, Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated as endophyte from Mimosa tenuiflora and causing post-harvest rot disease on fruits of Psidium guajava, respectively. Diaporthe inconspicua is emended to include a more detailed morphological description. Neopestalotiopsis egyptiaca is

24. Mineralogy, Micromorphology, and Genesis of Soils with Varying Drainage Along a Hillslope on Granitic Rocks of the Atlantic Forest Biome, Brazil
ABSTRACT Although the physical environment of the Atlantic Forest realm is well known, studies on the soil-landform relationships are fundamental to improve the management of soil resources to facilitate sustainable development. The purpose of this study was to evaluate a representative topossequence on the “Mares de Morros” landscape of deeply weathered
