1. Ituglanis boticario, a new troglomorphic catfish (Teleostei: Siluriformes: Trichomycteridae) from Mambaí karst area, central Brazil
A new subterranean and troglomorphic species of Ituglanis Costa and Bockmann, 1993 is described from the carbonatic karst area of northeastern Goiás state, upper Tocantins River Basin, central Brazil, representing the sixth subterranean species of the genus described from the same region. Ituglanis boticario sp. nov. is diagnosed by a combination of unusual

2. Diversidade morfoanatômica das estruturas subterrâneas de Arrojadoa Britton &Rose (Cactoideae, Cactaceae) / Morpho-anatomical diversity of the subterranean structures of Arrojadoa Britton &Rose (Cactoideae, Cactaceae)
Os diferentes taxa de Arrojadoa exibem uma variedade de estruturas subterrâneas, tanto de origem caulinar como radicular. O desenvolvimento de estruturas subterrâneas de origem caulinar em Arrojadoa é uma característica única entre as Cactaceae do leste do Brasil. No entanto, não há estudos sobre a diversidade morfológica das estruturas subterrâneas

3. Identificação de parâmetros de motor de indução linear tubular para extração de petróleo. / Identification of parameters of the tubular linear induction motor for the extraction of oil.
This work presents the identification of parameters of the tubular linear induction motor for the extraction of oil, called MATÆOS - which is the Portuguese acronym for Asynchronous Tubular Motor for Application to Subterranean Oil Extraction. The first step to the identification of the motor parameters was the implementation of the supervisory and control

4. Perfil geológico-geotécnico do subsolo ao longo do traçado do metrô de Goiânia / Geological-geotechnical profile of the subsoil along the Goiânia suway alignment
The building of the Goiânia subway is one of the items in the Proposal for Life Quality Improvement and Social Inclusion of the population of the Metropolitan Region of Goiânia (MRG), involving the municipal administrations of Goiânia and Aparecida de Goiânia. The proposal, which is part of the rearrangement of the MRG public transport system and follows

5. Avaliação da presença de Cryptosporidium spp. e Giardia spp. em aguas minerais naturais de nascentes e enteroparasitoses em duas comunidades rurais da cidade de Campos do Jordão, SP, Brasil / Evaluation of the presence of Cryptosporidium spp. and Giardia spp. in natural mineral waters from springs and enteroparasitosis in two rural communities in the city of Campos do Jordão, S.P., Brazil
The presence of protozoan parasites Cryptosporidium and Giardia mainly in water destined to the human consumption, assumed in the last 22 years, a great importance in Public Health due to the water transmission of its infectant forms. These protozoa cause gastroenteritis in human and in many animal species. The transmission of these parasites occurs by oral-

6. SubsÃdios para o uso e ocupaÃÃo do solo no municÃpio do Cabo de Santo Agostinho â PE, com Ãnfase para os recursos hÃdricos
The present work has as objective providing environmental and socioeconomic information which permits to subsidize a policy of occupation and land use whose fundamental is water resources management in Cabo de Santo Agostinho, a municipality situated on the southern coast of the state of Pernambuco. The methodological proceedings had as basis bibliographical

7. Ecologia comportamental e de interações com plantas hospedeiras em Phyllophaga cuyabana (Moser) (Coleoptera:Melolonthidae, Melolonthinae) e implicações para o seu manejo em cultura de soja
Soybean (Glycine max (L.) Merrill) is an introduced crop which has been expanding in Brazil during the last four decades. There are still some nutricional niches unoccupied or inefficiently explored by arthropods and other colonizing herbivores. Some insects with subterranean habitat have been considered soybean pests in Brazil in the last ten years, probabl

8. Agrobacterium-Mediated Transformation of Subterranean Clover (Trifolium subterraneum L.).
We have developed a rapid and reproducible transformation system for subterranean clover (Trifolium subterraneum L.) using Agrobacterium tumefaciens-mediated gene delivery. Hypocotyl segments from seeds that had been allowed to imbibe were used as explants, and regeneration was achieved via organogenesis. Glucose and acetosyringone were required in the co-cu

9. Biological clock in total darkness: The Clock/MOP3 circadian system of the blind subterranean mole rat
Blind subterranean mole rats retain a degenerated, subcutaneous, visually blind but functionally circadian eye involved in photoperiodic perception. Here we describe the cloning, sequence, and expression of the circadian Clock and MOP3 cDNAs of the Spalax ehrenbergi superspecies in Israel. Both genes are relatively conserved, although characterized by a sign

10. Split-Root Assays Using Trifolium subterraneum Show that Rhizobium Infection Induces a Systemic Response That Can Inhibit Nodulation of Another Invasive Rhizobium Strain
Subterranean clover plants possessing two equally infectible and robust lateral root systems (“split roots”) were used in conjunction with several specific mutant strains (derived from Rhizobium trifolii ANU843) to investigate a systemic plant response induced by infective Rhizobium strains. This plant response controls and inhibits subsequent nodulation

11. A subterranean mammal uses the magnetic compass for path integration
Path integration allows animals to navigate without landmarks by continuously processing signals generated through locomotion. Insects such as bees and ants have evolved an accurate path integration system, assessing and coding rotations with the help of a general directional reference, the sun azimuth. In mammals, by contrast, this process can take place th

12. Working underground: Respiratory adaptations in the blind mole rat
Mole rats (Spalax ehrenbergi superspecies) perform the heavy work of digging their subterranean burrows in Israel under highly hypoxic/hypercapnic conditions. Unlike most other mammals, they can achieve high levels of metabolic rate under these conditions, while their metabolic rate at low work rates is depressed. We explored, by comparing mole rats with whi
