Bauru: terra de cerrado ou floresta?

Bauru: region of cerrado ou forest? The city of Bauru is located in São Paulo State, where the maps showing native vegetation distribution does not clearly defi ne its nature. In order to clarify which types of native vegetation was found in this region, a bibliographic survey was performed, ranging from ancient documents prepared by naturalists describing this region and recent research results of floristic and phytosociological character. It is concluded that in Bauru, semideciduous seasonal forests overlays the northwestern and that cerrado comes over the southeast region. In riparian areas where the cerrado prevailed, there are still traces of swamp forests and swamp grasslands. In the border areas between forests and cerrado, the occurrence of vegetation transition is common, with two distinct types of it and other typical of these ecotone zones.

Utilização de análise de agrupamento na caracterização do perfil agrícola e climático da região sudeste do Estado de Mato Grosso

The multivariate analysis grouping was used to characterize the productive and climate profile of southeastern of Mato Grosso state. This technique allowed the junction of similar micro regions from characteristics of productivity and climatic, without the need for the assumption of the number or structure of the groups. Cluster analysis allowed the design of a mosaic of spatial heterogeneity regions. It established different profiles in the composition of groups, joining the more traditional in the culture of a species, or more productive, or those for the development of a particular culture. The results obtained by estimation of the climatic parameters and the multivariate procedures enabled the provision of systematic information that will allow farmers to better decision-making on the competitiveness and maintaining the flow of investment in agricultural sector southeastern Mato Grosso.

Macronutrientes em pepino enxertado em áreas com nematoides de galhas

Macronutrients in grafted cucumber in areas with gall nematodes. Grafting is an often recommended technique for cucumber culture in areas infested with gall nematodes. This study aimed to evaluate the content of macronutrients in grafted cucumber in two rootstocks on soil infested with Meloidogyne incognita race 2 or Meloidogyne javanica, since they may decrease the effectiveness of water and nutrient absorption. One evaluated 9 treatments (factorial 3x3: nongrafted hybrid cucumber Tsuyataro, grafted on squash hybrid Shelper or grafted on squash hybrid Excitte Ikki x without inoculation, inoculation with M. incognita or M. javanica), in a randomized blocks design, with 4 replicates and 6 plants per plot. The characteristics evaluated were: macronutrient content at 72 days after transplantation and macronutrient content at the end of the cycle (99 days after transplantation). The nutrient contents evaluated didn’t differ according to the nematode species (with or without inoculation), however, there’re differences with regard to the rootstocks, with higher values of phosphorus and potassium in grafted plants and higher values of magnesium, calcium, and sulfur in nongrafted plants at the end of cycle.

What can light scattering spectroscopy do for membrane-active peptide studies

Highly charged peptides are important components of the immune system and belong to an important family of antibiotics. Although their therapeutic activity is known, most of the molecular level mechanisms are controversial. A wide variety of different approaches are usually applied to understand their mechanisms, but light scattering techniques are frequently overlooked. Yet, light scattering is a noninvasive technique that allows insights both on the peptide mechanism of action as well as on the development of new antibiotics. Dynamic light scattering (DLS) and static light scattering (SLS) are used to measure the aggregation process of lipid vesicles upon addition of peptides and molecular properties (shape, molecular weight). The high charge of these peptides allows electrostatic attraction toward charged lipid vesicles, which is studied by zeta potential (zeta-potential) measurements.

A distinct tymovirus infecting Cassia hoffmannseggii in Brazil

Leaves of Cassia hoffmannseggii, a wild fabaceous species found in the Atlantic Forest, with a severe mosaic symptom were collected in Pernambuco State, Brazil. By transmission electron microscopy, two types of virus particles were found: the first was recognized as particles of a potyvirus, which was later identified as Cowpea aphid-borne mosaic virus; and the second was isometric and present in high concentration. The observation of vesicles at the periphery of chloroplasts suggested a tymovirus infection, which was confirmed by subsequent assays. A serological assay against several tymovirus antisera resulted in positive reaction of this tymo-like virus with an antiserum of Passion fruit yellow mosaic virus. By means of RT-PCR and using degenerated primers for the conserved region of RNA-dependent RNA polymerase (RdRp) gene of tymoviruses, a specific DNA fragment was amplified and sequenced. Based on this sequence, a specific forward primer was synthesized and successfully used to amplify the 3' terminal genome region, containing the partial RdRp gene and the complete coat protein (CP) sequences. The CP was 188 amino acids (aa) long, and the highest CP aa identity was observed with Kennedya yellow mosaic virus (61 %). Based on the current ICTV demarcation criterion, this isolate was considered as a distinct tymovirus and tentatively named as Cassia yellow mosaic-associated virus.

Timing of ontogenetic changes of two cranial regions in Sotalia guianensis (Delphinidae)

Despite the fact that heterochronic processes seem to be an important process determining morphological evolution of the delphinid skull, previous workers have not found allometric scaling as relevant factor in the differentiation within the genus Sotalia. Here we analyzed the skull ontogeny of the estuarine dolphin S. guianensis and investigate differential growth and shape changes of two cranial regions the neurocranium and the face in order to evaluate the relevance of cranial compartmentalization on the ontogeny of this structure. Our results show that, even though both cranial regions stop growing at adulthood, the face has higher initial growth rates than the neurocranium. The rate of shape changes is also different for both regions, with the face showing a initially higher, but rapidly decreasing rate of change, while the neurocranium shows a slow decreasing rate, leading to persistent and localized shape changes throughout adult life, a pattern that could be related to epigenetic regional factors. The pattern of ontogenetic shape change described here is similar to those described for other groups of Delphinidae and also match intra and interspecific variation found within the family, suggesting that mosaic heterochrony could be an important factor in the morphological evolution of this group.
