Review of Spanish Discard information of megrim (Lepidorhombus whiffiagonis) in ICES Sub-areas VI , VII and Div. VIIIabd

Trawlers Spanish discards obtained on board commercial vessels in Sub-areas VI and VII in 1988, 1989, 1994, 1999-200-2004 are present to: 1. Validate the discard estimation of megrim onboard comparing length distribution of retained fish on board with landed fishes. 2. Compare estimation megrim discarded following two methodologies: primary sampling unit as hauls or as fishing trips. Examine possible modification on discards estimations in years where results obtained by different methods were relevant. 3. Analyse possible differences in discard patter along the sampled perio

Preliminary results on Northern hake from the “Spanish Discard Sampling Programme”

The “Spanish Discard Sampling Programme” was started in 1988, however it has not had a continuous implementation in time. Results on Northern hake discard were obtained sampling the Spanish trawl fishery operating in the Northern hake distribution area. Discarding strategy varies between fleets, depending mainly on the target species of the fleet. Differences along the time series were probably due to market changes more than to the abundance of the species. In the years with a higher sampling quality, 2003 and 2004, the total level of Northern hake discard was estimated to be around 5% in weight and between 11-15% in number, respectively. Discards were compounded by ages from 0 to 3, mainly ages 1 and 2

Testing the Gamma-Ray Burst Pulse Start Conjecture

We test the hypothesis that prompt gamma-ray burst pulse emission starts simultaneously at all energies (the Pulse Start Conjecture). Our analysis, using a sample of BATSE bursts observed with four channel, 64-ms data and performed using a pulse fit model, generally supports this hypothesis for the Long GRB class, although a few discrepant pulses belong to bursts observed during times characterized by low signal-to-noise, hidden pulses, and/or significant pulse overlap. The typical uncertainty in making this statement is < 0.4 s for pulses in Long GRBs (and < 0.2 s for 40% of the pulses) and perhaps < 0.1 s for pulses in Short GRBs. When considered along with the Epk decline found in GRB pulse evolution, this result implies that energy is injected at the beginning of each and every GRB pulse, and the subsequent spectral evolution, including the pulse peak intensity, represents radiated energy losses from this initial injection.Comment: 34 pages, 17 figures, 3 tables, accepted for publication in The Astrophysical Journa

Quantifying the effect of Tmax extreme events on local adaptation to climate change of maize crop in Andalusia for the 21st century

Extreme events of Tmax can threaten maize production on Andalusia (Ruiz-Ramos et al., 2011). The objective of this work is to attempt a quantification of the effects of Tmax extreme events on the previously identified (Gabaldón et al., 2013) local adaptation strategies to climate change of irrigated maize crop in Andalusia for the first half of the 21st century

Integrable Kondo impurity in one-dimensional q-deformed t−Jt-J models

Integrable Kondo impurities in two cases of the one-dimensional q-deformed $t-J$ models are studied by means of the boundary ${\bf Z}_2$-graded quantum inverse scattering method. The boundary $K$ matrices depending on the local magnetic moments of the impurities are presented as nontrivial realizations of the reflection equation algebras in an impurity Hilbert space. Furthermore, these models are solved by using the algebraic Bethe ansatz method and the Bethe ansatz equations are obtained.Comment: 17 pages, RevTex, No figures, final version to appear in J. Phys.

Trawl Anglerfish Discard Estimates and Patterns in the Spanish Northeast Atlantic Fisheries.

Discards estimates from Spanish bottom otter trawl of anglerfish, Lophius budegassa (black anglerfish) and L. piscatorius (white anglerfish), in Northeast Atlantic Ocean (ICES Sub-areas VI, VII and Divisions VIIIabd) are presented in this paper. Information was obtained by observers on board in different discard programs carried out by Spanish Research Institutes. Total discards obtained by the different raising procedures were very similar and total discard raised by effort (number of trips) as a simple estimator was assumed as the adequate value. Values in weight range from 4 t to 590 t, and from 4 t to 320 t for white and black anglerfish respectively in Sub-areas VI and VII. Length distributions of discarded anglerfish (Sub-areas VI and VII) show that most of the specimens are juvenile individuals. Discards estimations show a high variability in weight and number along the period studied. Yearly abundance of juveniles in the area is a factor to understand the variability of discard quantities. This trend in Sub-areas VI and VII is reflected by similar pattern between juveniles (length < 31cm) discards estimations and recruitment indices (age 0) obtained by French (FR-EVHOES) for black anglerfish, and Irish (IR-IGFS) for white anglerfish. Inter-annual variation may also be explained by legal restriction on minimum weights (DCR) laid down in 2000 due to change in onboard sorting procedures

Rice Galaxy: An open resource for plant science

Background: Rice molecular genetics, breeding, genetic diversity, and allied research (such as rice-pathogen interaction) have adopted sequencing technologies and high-density genotyping platforms for genome variation analysis and gene discovery. Germplasm collections representing rice diversity, improved varieties, and elite breeding materials are accessible through rice gene banks for use in research and breeding, with many having genome sequences and high-density genotype data available. Combining phenotypic and genotypic information on these accessions enables genome-wide association analysis, which is driving quantitative trait loci discovery and molecular marker development. Comparative sequence analyses across quantitative trait loci regions facilitate the discovery of novel alleles. Analyses involving DNA sequences and large genotyping matrices for thousands of samples, however, pose a challenge to non−computer savvy rice researchers. Findings: The Rice Galaxy resource has shared datasets that include high-density genotypes from the 3,000 Rice Genomes project and sequences with corresponding annotations from 9 published rice genomes. The Rice Galaxy web server and deployment installer includes tools for designing single-nucleotide polymorphism assays, analyzing genome-wide association studies, population diversity, rice−bacterial pathogen diagnostics, and a suite of published genomic prediction methods. A prototype Rice Galaxy compliant to Open Access, Open Data, and Findable, Accessible, Interoperable, and Reproducible principles is also presented. Conclusions: Rice Galaxy is a freely available resource that empowers the plant research community to perform state-of-the-art analyses and utilize publicly available big datasets for both fundamental and applied science
