Summary Females of the mangrove crab Ucides cordatus were collected in a monthly basis along a 2-year period at the mangrove areas of Iguape, SP, Brazil. Ovigerous individuals were measured (CW, carapace width) and weighed (WW, wet weight). Each brood was weighed (WWE, wet weight of eggs), dried (DWE, dry weight of eggs) and the number of eggs (EN) was recorded. Scatter plots for the relationships EN/CW, EN/WW and EN/WWE were produced, and the data were subjected to regression analysis. Relative average ...

[Arenaeus cribrarius females were collected over a 12-month period with nets in the Ubatuba littoral zone, Brazil. Ovigerous individuals were measured (CW = carapace width excluding lateral spines) and weighed (WW = wet weight). Each egg brood was weighed (WE = wet weight), dried, and the number of eggs (EN) counted. Scatterplots from EN/CW, EN/WW, and EN/WE were submitted to regression analyses. Mean relative fecundity (F′) was calculated in each month/season to assess seasonal variation of reproductive intensity. ...

The effects of supplemental water supplied as large events, 25 mm per month, or as frequent small events, 6 mm per week, and available nitrogen on density, aboveground biomass and species composition of an annual plant community were studied in the northern Chihuahuan Desert. The amendments of water and N had no effect on total annual plant density. However, supplemental water resulted in increased density of eight species and nitrogen fertilization produced increased densities in nine species. ...

Summary The rth3 ( roothairless 3 ) mutant is specifically affected in root hair elongation. We report here the cloning of the rth3 gene via a PCR‐based strategy (amplification of insertion mutagenized sites) and demonstrate that it encodes a COBRA‐like protein that displays all the structural features of a glycosylphosphatidylinositol anchor. Genes of the COBRA family are involved in various types of cell expansion and cell wall biosynthesis. The rth3 gene belongs to a monocot‐specific clade of the ...

The mechanisms by which plants restrict the growth of pathogens include transient activation of numerous defense‐related genes. Box P is a putative cis ‐acting element of a distinct group of such genes, including those encoding the enzyme phenylalanine ammonia‐lyase (PAL). A DNA‐binding activity to Box P was identified in nuclear extracts from cultured parsley cells and a cDNA encoding the protein BPF‐1 ( B ox P ‐binding F actor) partially characterized. BPF‐1 binds to this element with specificity similar ...

Etched1 (et1) is a pleiotropic, recessive mutation of maize that causes fissured and cracked mature kernels and virescent seedlings. Microscopic examinations of the et1 phenotype revealed an aberrant plastid development in mutant kernels and mutant leaves. Here, we report on the cloning of the et1 gene by transposon tagging, the localization of the gene product in chloroplasts, and its putative function in the plastid transcriptional apparatus. Several alleles of Mutator (Mu)-induced et1 mutants, ...

This paper presents experimental and theoretical results concerning the corrosion inhibitor effect of imidazole and five of its derivatives on iron surface. Gravimetric methods and polarization curves were the experimental techniques used in this study. The polarization curves showed that the inhibitors have an anodic role on the electrochemical process. Weight-loss measurements indicated that the adsorption process obeys Langmuir's isotherm. The theoretical study was done using ab initio calculations ...

Intravenous infusions of highly concentrated NaCl (2,400 mosmol/l; infused volume 4 ml/kg; equivalent to 10% of shed blood), given to lightly anesthetized dogs in severe hemorrhagic shock, rapidly restore blood pressure and acid base equilibrium toward normality. No appreciable plasma volume expansion occurs for at least 12 h, indicating that fluid shift into the vascular bed plays no essential role in this response. Initial effects wee sustained indefinitely; long term survival was 100%, compared ...

Textile industrial wastewaters have significant quantities of dyes. Adsorption processes using industrials rejects may help in the treatment of these effluents. In this context, uptake of Reactive Blue 5G dye by babassu coconut shell activated carbon was studied with upstream flow fixed-bed experiments. First, the minimum flow rate that minimizes the diffusion effects of 4 mL/min was chosen within the range investigated (2-10 mL/min). Then, the breakthrough curves were obtained for this flow rate ...

For over 30 years it has been established that the Entamoeba histolytica protozoan included two biologically and genetically different species, one with a pathogenic phenotype called E. histolytica and the other with a non-pathogenic phenotype called Entamoeba dispar. Both of these amoebae species can infect humans. E. histolytica has been considered as a potential pathogen that can cause serious damage to the large intestine (colitis, dysentery) and other extraintestinal organs, mainly the liver ( ...

Invasive predators are one of the causes of population declines of anurans around the world. The American Bullfrog (Lithobates catesbeianus) stands out among these predators. Based on field observations and stomach content analysis, predation on native anurans by invasive Bullfrogs was investigated in two localities of Southeastern Brazil. The spatial variation in predation and similarity in microhabitat use by native species and Bullfrogs were also determined. Anurans of the families Bufonidae, ...

The treatment conditions (caffeine, Fe(2+) and H(2)O(2) concentrations) were defined by experimental design. The optimized conditions for each variable, obtained using the response factor (% mineralization), were: 52.0 mg L(-1)caffeine, 10.0 mg L(-1)Fe(2+) and 42.0 mg L(-1)H(2)O(2) (replaced in kinetic experiments). Under these conditions, in ultrapure water ( ...

We report on the radiative and nonradiative emission processes from semimagnetic Pb1−xMnxSe quantum dots (QDs) embedded in a glass matrix. Emissions between the 4T1 → 6A1 states of Mn2+ ions located in the PbSe semiconductor gap were not observed. Electron Paramagnetic Resonance spectra confirmed that Mn2+ ions are located in two distinct QD sites. Furthermore, Magnetic Force Microscopy confirmed the formation of high quality Pb1−xMnxSe QDs with uniformly distributed magnetic moments.

Carbofuran is a nematicide insecticide with a broad spectrum of action. Carbofuran has noxious effects in several species and has been banned in the USA and Europe; however, it is still used in Brazil. Aquatic organisms are not only exposed to pesticides but also to manufactured nanoparticles, and the potential interaction of these compounds therefore requires investigation.
