1. Accessing the subterranean ant fauna (Hymenoptera: Formicidae) in native and modified subtropical landscapes in the Neotropics
Resumo: Vários estudos têm caracterizado e delimitado assembleias de formigas subterrâneas. A extração de solo, um dos métodos utilizados para amostragem dessa fala, implica na remoção de monólitos. Um dos métodos mais utilizados na extração de monólitos é chamado TSBF (desenvolvido pelo Programa Tropical Soil Biology and Fertility). Esse méto

2. A valepotriate-enriched fraction from Valeriana glechomifolia Meyer inhibits leukocytes migration and nociception in formalin test in rodents
Abstract Previous pre-clinical studies demonstrated that a valepotriates enriched fraction from Valeriana glechomifolia F.G. Mey., Caprifoliaceae, was effective against lipopolysaccharide from Escherichia coli (LPS)-induced sickness behavior as well as significantly decreased the cortical expression of pro inflammatory cytokines interleukin-1β and tumor nec

3. High cellulolytic activities in filamentous fungi isolated from an extreme oligotrophic subterranean environment (Catão cave) in Brazil
Abstract Abstract: Isolation and screening of new fungal strains from extreme and understudied environments, such as caves, is a promising approach to find higher yields enzyme producers. Cellulolytic fungal strains isolated from a Brazilian cave were evaluated for their enzymatic production after submerged (SmF) and solid-state fermentation (SSF). After SmF

4. Modelagem da transferência de calor de ambientes subterrâneos no programa de simulação EnergyPlus
Resumo A temperatura do solo é um dos fatores mais influentes nas avaliações de desempenho térmico de ambientes subterrâneos e quase sempre é desconsiderada. Por isso, é necessário avaliar essa influência devido à interação do solo com a edificação, pois a transferência de calor através de paredes e pisos subterrâneos tem uma extensão signi

5. Skull shape and size variation within and between mendocinus and torquatus groups in the genus Ctenomys (Rodentia: Ctenomyidae) in chromosomal polymorphism context
Abstract We tested the association between chromosomal polymorphism and skull shape and size variation in two groups of the subterranean rodent Ctenomys. The hypothesis is based on the premise that chromosomal rearrangements in small populations, as it occurs in Ctenomys, produce reproductive isolation and allow the independent diversification of populations

6. A Numerical Mode-Matching Method Based on Multiple-Knot Cubic B-Splines Applied to the Analysis of Well-Logging Tools
Abstract The numerical mode-matching (NMM) technique is a very efficient approach to analyze well-logging tools used for hydrocarbon exploration. This problem is typically modeled as a cylindrically layered medium (subterranean formation) including both horizontal and vertical stratifications. In this paper, we present a new NMM formulation based on the use

7. Influence of substrate on the richness and composition of Neotropical cave fauna
ABSTRACT The food base in the subterranean environment consists mainly of allochthonous materials. In this environment the resources are distributed generally in a heterogeneous dispersed way and the distribution of resources and their availability determine where the terrestrial invertebrates will reside, which is important for understanding ecological rela

8. A new species of stygobitic aeglid from lentic subterranean waters in southeastern Brazil, with an unusual morphological trait: short pleopods in adult males
Abstract Aegla charon n. sp. is endemic to the “Lago Subterrâneo” cave from the Alto Ribeira karst region, southeastern Brazil. The most remarkable morphological trait observed in the new species was the presence of partially developed pair of uniramous pleopods 2‒5 in adult male specimens, whereas the absence of these pleonal appendages is the genera

9. Variation of some chemical and functional properties of Bambara groundnut (Voandzeia Subterranean L. Thouars) during sort time storage
Abstract The storage susceptibility of Bambara groundnut (B. G.) (Voandzeia Subterranean (L.) Thouars) to Callosobruchus maculatus and chemical and functional properties of 11 varieties form Far-North of Cameroon were investigate using standard analytical methods. Storage susceptibility shown that, after five months within treatment, C. maculatus destroy 10

10. Foraging pattern and harvesting of resources of subterranean stingless bee Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae: Meliponini)
RESUMO A atividade de vôo das abelhas é influenciada por fatores ambientais, como temperatura, umidade e intensidade luminosa; e pelas condições internas da colônia. Informações sobre a atividade externa das abelhas é de grande importância, pois proporciona dados importantes para o conhecimento da biologia das espécies, fornecendo subsídios para o

11. A zona hiporréica e as suas funções: revisão e estado da arte da pesquisa na região neotropical
ResumoA zona hiporréica, como ecótono de ligação entre a superfície e as águas subterrâneas, é parte funcional seja dos ecossistemas fluviais seja das águas subterrâneas. As características hidrológicas, as características químicas, biológicas e metabólicas são específicas desta zona, não pertencendo verdadeiramente nem a superfície nem �

12. Taxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare taxa. Studies investigating the biological diversity in Neotropical caves are relatively rare and recent, a
