Study of the mayfly order Ephemeroptera (Insecta) in Brazil: a scienciometric review

Study of the mayfly order Ephemeroptera (Insecta) in Brazil: a scienciometric review. Despite an increase in the number of studies in recent years of the aquatic insect order Ephemeroptera (the mayflies) much still remains to be learnt. In order to identify the current state of knowledge of this group in Brazil, we performed a scienciometric analysis with the purpose of identifying the strong and weak points of Brazilian research into the group. Our research used the "Institute for Scientific Information - ISI" database and was based on the abstracts, titles and keywords of manuscripts published between 1992 and 2011. We selected the papers with the combination of the words "Ephemeroptera" and "Brazil*" based on a search in February 2012. We analyzed 92 articles, and noted a lack of studies in some Brazilian states, no specific studies about some families, and an absence of phylogenetic studies. To improve ecological studies, it is necessary to fine-tune taxonomic resolution. Moreover, there is a lack of studies investigating the environmental variables which influence the distribution of mayflies. Despite these gaps, if the rate of publication with mayflies proceeds at the same pace, we anticipate that many of these knowledge gaps will be closed.

Minimum requirements for application of ink dating methods based on solvent analysis in casework

Several ink dating methods based on solvents analysis using gas chromatography/mass spectrometry (GC/MS) were proposed in the last decades. These methods follow the drying of solvents from ballpoint pen inks on paper and seem very promising. However, several questions arose over the last few years among questioned documents examiners regarding the transparency and reproducibility of the proposed techniques. These questions should be carefully studied for accurate and ethical application of this methodology in casework. Inspired by a real investigation involving ink dating, the present paper discusses this particular issue throughout four main topics: aging processes, dating methods, validation procedures and data interpretation. This work presents a wide picture of the ink dating field, warns about potential shortcomings and also proposes some solutions to avoid reporting errors in court.

Aislamiento, identificación, clonación y análisis filogénico de la microalga Prorocentrum minimum (PAVILLARD) J. Schiller 1933 Aislada de la Bahía del Callao - Perú

Las Floraciones Algales Nocivas (FAN) o Mareas Rojas son decoloraciones del agua visible a simple vista debido a la proliferación de uno o más microorganismos planctónicos como las microalgas, estas pueden alcanzar niveles altos y producir efectos adversos a la salud humana, como también, causar daños a otros organismos marinos cercanos a la costa. Por tal motivo, existió el interés de aislar, identificar y hacer un estudio filogenético de la especie Prorocentrum minimum encontrada en la Bahía del Callao- Perú. Se realizaron varias tomas de muestras de agua de mar para su posterior identificación morfológica, se les efectuó la técnica de purificación de la microalga, y a su vez, se adquirió un estándar de Prorocentrum minimum del Instituto Provasoli- Guillard National Center for Culture of Marine Phytoplankton (CCMP), USA. Se realizó la curva de crecimiento para la concentración de la densidad microalgal, posteriormente se efectuó la extracción de ADN y la filogenia molecular a partir de las secuencias de las subunidades del ribosoma LSU rRNA de la especie Prorocentrum minimum. Se identificó P. minimum y P gracile, que fueron especies epibentónicos cercanas por ser más recientes evolutivamente. Para la confirmación de la presencia ausencia de alguna biotoxina marina en el cultivo de Prorocentrun minimum, se estableció un análisis cuantitativo de la dosis respuesta del animal en el bioensayo en ratón. Se logró obtener la purificación de cultivo de Prorocentrum minimum y estandarizar el protocolo de trabajo, se confirmó la filogenia de la especie de microalgas. No se logró obtener la toxina DSP del cultivo de la microalga.

A Variant of Higher-Order Anti-Unification

We present a rule-based Huet’s style anti-unification algorithm for simply-typed lambda-terms in ɳ long β normal form, which computes a least general higher-order pattern generalization. For a pair of arbitrary terms of the same type, such a generalization always exists and is unique modulo α equivalence and variable renaming. The algorithm computes it in cubic time within linear space. It has been implemented and the code is freely available

Evaluación poblacional de Argopecten purpuratus (Lamarck, 1819) en bahía Independencia. Pisco, diciembre 2010

En diciembre 2010, se realizó una evaluación poblacional de la concha de abanico (Argopecten purpuratus) con la finalidad de determinar la distribución, abundancia y estructura poblacional en los bancos naturales de bahía Independencia, se empleó el muestreo al azar estratificado por profundidad. Las tallas fluctuaron entre 4 y 101 mm de altura valvar, media en 61,4 mm y se registró el 58,2% de ejemplares con tallas mayores a la mínima de extracción (≥65 mm). Predominaron ejemplares desovantes (92,1%). Se distribuyó formando agregaciones con concentraciones entre 1 y 5 ind.m-2. La población y biomasa total se estimó en 12,47 millones (±25,6%) y 948,2 t (±27,7%), respectivamente. Tunga y La Pampa se constituyeron como las áreas más importantes en población y biomasa.

Development and Validation of Single Nucleotide Polymorphisms (SNPs) Markers from Two Transcriptome 454-Runs of Turbot (Scophthalmus maximus) Using High-Throughput Genotyping

The turbot (Scophthalmus maximus) is a commercially valuable flatfish and one of the most promising aquaculture species in Europe. Two transcriptome 454-pyrosequencing runs were used in order to detect Single Nucleotide Polymorphisms (SNPs) in genesrelated to immune response and gonad differentiation. A total of 866 true SNPs were detected in 140 different contigs representing 262,093 bp as a whole. Only one true SNP was analyzed in each contig. One hundred and thirteen SNPs out of the 140 analyzed were feasible (genotyped), while Ш were polymorphic in a wild population. Transition/transversion ratio (1.354) was similar to that observed in other fish studies. Unbiased gene diversity (He) estimates ranged from 0.060 to 0.510 (mean = 0.351), minimum allele frequency (MAF) from 0.030 to 0.500 (mean = 0.259) and all loci were in Hardy-Weinberg equilibrium after Bonferroni correction. A large number of SNPs (49) were located in the coding region, 33 representing synonymous and 16 non-synonymous changes. Most SNP-containing genes were related to immune response and gonad differentiation processes, and could be candidates for functional changes leading to phenotypic changes. These markers will be useful for population screening to look for adaptive variation in wild and domestic turbot
