Estimates for Carbon Stocks in Soil under Humid Grassland Areas in the Federal District of Brazil

open journal of Ecology 2014年第13期4卷 777-787页

The soils that lay below humid ecosystems are characterized as being significant holders of carbon. Because of the great susceptibility of this type of environment to anthropic changes, expressive quantities of carbon stored in the soil can be released into the atmosphere. In the Cerrado biome (Brazil), only a few types of vegetation have had carbon storage levels in their soil estimated. The main purpose of this study was to obtain basic quantitative parameters for carbon storage and to identify the general aspects of soil in regions where there exists Humid Grasslands (Campo Limpo úmido), a kind of humid area phytophysiognomy found in the Cerrado. We selected 6 regions of the Federal District with this kind of vegetation formation, characterized by low anthropic impact and located either in the interior or in the proximity of specially protected areas. In each one of the sampled regions, we marked a transect with 4 equidistant points and collected material at 7 different levels of depth: 0 - 5, 5 - 10, 10 - 20, 20 - 30, 30 - 40, 40 - 50 and 50 - 60 cm. We obtained 168 samples, with 84 related to Humid Grassland areas in gleysols and 84 samples related to areas in plinthosols—types of soil dominant in this environment. We determined the texture, bulk density and concentration of nitrogen and carbon at each depth. The average concentration of carbon for Humid Grassland areas was 55.19 ***-1, with an average of 61.65 ***-1 for Gleysols and 48.73 ***-1 for Plinthosols. The soil samples displayed distinct textural differences between gleysols and plinthosols. There were no significant differences in soil density (0.75 ***-3 for Gleysols and 0.72 ***-3 for Plinthosols). The average concentration of nitrogen was 20.66 ***-1, with 23.98 ***-1 for Gleysols and 17.34 ***-1 for Plinthosols. The average carbon storage for Humid Grassland areas, down to 60 cm deep, was 244.17 mg C ha-1 and the total estimated stock for these areas in the Federal District was 206.71 G

Divergence in the ovipositional behavior of the Papilio glaucus group

Insect Science 2008年第4期15卷 361-367页

作者： rodrigo j. Mercader j. Mark Scriber Department of Entomology Michigan State University East Lansing MI48824 USA

This study contrasts the ovipositional profiles of four members of the Papilio glaucus group, P. glaucus, P. multicaudatus, P. canadensis, and P. rutulus. We used seven choice oviposition bioassays containing leaves from hosts in seven plant families utilized by members of the P. glaucus group. Specifically, we contrast the overall ovipositional profiles of these species and their acceptance of a host in a novel plant family （Populus tremuloides： Salicaceae） and a host in a putatively ancestral host plant family （Liriodendron tulipifera： Magnoliaceae）. Significant differences were observed between the ovipositional profiles of P. glaucus and P. multicaudatus relative to each other and to P. canadensis and P. rutulus. In contrast, no significant differences were observed between the ovipositional profiles of P. canadensis and P. rutulus, which were also the only species that accepted P. tremuloides. Unlike the acceptance of P. tremuloides, the acceptance of L. tulipifera was present throughout the group despite the inability of the larvae of most species in the group to utilize this host. These results support the prediction of the ＂hierarchical threshold model＂ that ancestral host plants are likely to be retained in the ovipositional hierarchy while novel hosts should only be accepted by derived populations.

The aim of this statement is to give a contribution towards the future, where for all, materials are the driven force for the transformations we aim to reach and for which a global common house is imperative to be established, as the International Union of Materials Research Societies, IUMRS aims to be the central vehicle for such, aiming to boost innovation to its maxima, without compromising vital global principles of opening science to the *** is consolidated by 4 main principles: Circular Economy; Trans disciplinarity; Horizontal cross cutting synergy(the introduced Metro Station concept); look always to the Big Picture and not to silos. This means that the traditional vertical thematic topics that were essential to define so far, the so-called road maps for something should be revisited and reconverted towards much larger horizontal scenarios.

Cross-talk between T-cells and gut-microbiota in neurodegenerative disorders

作者： rodrigo Pacheco Departamento de Ciencias Biológicas Facultad de Ciencias de la Vida Universidad Andres Bello Laboratorio de Neuroinmunología Fundación Ciencia & Vida

The emerging role of gut microbiota as a key player in the development of neurodegenerative disorders: Mammals have evolved together with commensal microbiota to establish a symbiotic relationship in which they regulate reciprocally by synthesizing and responding to several common chemical substances. In this regard, gut microbiota constitutes a consortium of bacteria that not only participates in the degradation of nutrients, but also produces metabolites, fatty acids and neurotransmitters that can act on the enzymes and receptors expressed in eukaryotic cells, which considerably affects the physiology of the host and contribute to maintaining homeostasis (Lyte, 2013).
