Caracterização hidroquímica do sistema aquífero Tubarão no município de Americana/SP

The growing interest in the use of groundwater resources is directly related to the economic advantages that the groundwater exploitation offers when compared to surface waters. This happens especially in large urban centers, such as the city of Americana / SP, where the rivers are increasingly contaminated by household and industrial waste. Therefore, this study aimed to characterize the Tubarão Aquifer System, in the city of Americana, to identify and evaluate the spatial distribution of different hydrogeochemical facies as well as understand the rock-fluid interaction through the construction of a conceptual hydrogeochemical model. This study was made based on the recognition of the possible chemical reactions that print the chemical characteristics of groundwater in the area. To do the job, there were two water sampling campaigns of all deep wells used by the City of Americana public water supply. From the results of hydrochemical, classification of water was made by Piper and Stiff diagrams as well as geostatistical data using cluster analysis of principal components. Based on information from the profiles obtained from the survey SIAGAS as well as in geological profiles provided by the city of Americana, we sought to detail the subsurface geology of the Subgroup Itararé in the city of Americana. The results obtained allowed the identification of three hydrochemical types in the study area: Bicarbonated calcium-sodium (1), bicarbonate sodium (2) and sodium chloride (3). The waters have bicarbonate alkaline pH to alkaline and can be considered weakly saline, with electrical conductivity values of around 161 mS / cm. Samples classified as sodium bicarbonate average of 174.99 mS / cm. The pH values ranging from 6.74 to 7.99, averaging 7.52. For the group of waters classified as sodium chloride, conductivity average is 164.32 mS / cm and pH values ranging... (Complete abstract click electronic access below)

Radioatividade e hidroquímica em águas subterrâneas do município de Botucatu (SP)

The main objective of this study is to determine the activity of Po-210, Pb-210 and gross alpha/beta radioactivity in groundwater collected in Botucatu, municipality of the São Paulo state, Brazil. Samples were collected in wells to perform the radiochemical analysis. Most wells are registered in DAEE, Sabesp or CPRM. The activity of polonium was obtained by the method of alpha spectrometry, held in LABIDRO at UNESP, Rio Claro. All samples showed radioactivity values below the maximum allowed by WHO, that are: gross alpha radioactivity = 0,5 Bq/L, gross beta radioactivity = 1,0 Bq/L, Po210 = 0,2 Bq/L and Pb210 = 0,1 Bq/L. The results of hydrochemical analysis were compared with the 1469 Ordinance of the Health Ministry, and all values are bellow the maximum allowed. The data also allowed obtain the samples classification using the Piper diagram. The samples AAB, Quinta do Manacás, Faz. Quatro Irmãs, Sesi, Sitio São José and ITE are classified as calcic bicarbonate; the samples Staroup and Caio are potassic; the samples Banespa and BTC are bicarbonate and mixed interms of dissolved cations; Sitio das Palmeiras sample is sodium bicarbonate; the sample Faz. São Paulo is chlorinated calcic; the sample Sítio Btu-Pardinho chlorinated and mixed interms of dissolved cations

Imputation of microsatellite alleles from dense SNP genotypes for parentage verification across multiple Bos taurus and Bos indicus breeds

To assist cattle producers transition from microsatellite (MS) to single nucleotide polymorphism (SNP) genotyping for parental verification we previously devised an effective and inexpensive method to impute MS alleles from SNP haplotypes. While the reported method was verified with only a limited data set (N = 479) from Brown Swiss, Guernsey, Holstein, and Jersey cattle, some of the MS-SNP haplotype associations were concordant across these phylogenetically diverse breeds. This implied that some haplotypes predate modern breed formation and remain in strong linkage disequilibrium. To expand the utility of MS allele imputation across breeds, MS and SNP data from more than 8000 animals representing 39 breeds (Bos taurus and B. indicus) were used to predict 9410 SNP haplotypes, incorporating an average of 73 SNPs per haplotype, for which alleles from 12 MS markers could be accurately be imputed. Approximately 25% of the MS-SNP haplotypes were present in multiple breeds (N = 2 to 36 breeds). These shared haplotypes allowed for MS imputation in breeds that were not represented in the reference population with only a small increase in Mendelian inheritance inconsistancies. Our reported reference haplotypes can be used for any cattle breed and the reported methods can be applied to any species to aid the transition from MS to SNP genetic markers. While ~91% of the animals with imputed alleles for 12 MS markers had ≤1 Mendelian inheritance conflicts with their parents' reported MS genotypes, this figure was 96% for our reference animals, indicating potential errors in the reported MS genotypes. The workflow we suggest autocorrects for genotyping errors and rare haplotypes, by MS genotyping animals whose imputed MS alleles fail parentage verification, and then incorporating those animals into the reference dataset.

Riqueza, abundância e dieta de morcegos (Chiroptera) em floresta de eucaliptos

Os quirópteros apresentam grande diversidade e variação de hábitos alimentares, desempenhando um importante papel ecológico, se destacando pela dispersão de sementes que auxilia na conservação e restauração de ambientes degradados. Em caso de monoculturas, espera-se que reflorestamentos mais antigos com sub-bosque bem desenvolvido abriguem comunidades com maior diversidade de espécies se comparados a reflorestamentos utilizados para fins comerciais. O objetivo deste estudo é conhecer a riqueza, abundância e diversidade de morcegos e a dieta das espécies frugívoras em uma área refloresta por Eucalyptus spp., a Floresta Estadual Edmundo Navarro de Andrade localizada em Rio Claro - SP. As capturas ocorreram entre maio de 2014 e 2015, utilizando redes de neblina e um esforço amostral de 9072 m².h. As fezes encontradas foram coletadas, identificadas usando-se uma coleção de referência em laboratório e associadas às espécies de morcegos. Foi realizado um teste de germinação com Piper amalago para verificar o efeito da passagem de sementes pelo trato digestivo dos morcegos. São apresentados dados de dominância, constância, estimativas de riqueza (Chao1, Jackknife2) e diversidade (Shannon-Wiener) de morcegos, assim como índice de valor de importância de interação (Murray) para plantas e morcegos e a velocidade e a porcentagem germinativa de sementes de Piper amalago. Foram capturados 86 indivíduos de nove espécies de quirópteros pertencentes a duas famílias. As espécies encontradas são, em sua maioria, generalistas, sendo a mais abundante Artibeus lituratus, seguido de Carollia perspicillatta, esta se alimentou de 10 espécies diferentes de plantas, tendo o maior valor no índice de importância, enquanto Piper aduncum foi a planta consumida pelo maior número de morcegos na área de estudo. As espécies de plantas consumidas são principalmente pioneiras como Piperaceae e Solanaceae, que contribuem para a...
