    Abstract Efterafgrøder kan have stor positiv effekt på såvel udbytter som berigelse af jordkvalitet. I denne session præsenteres resultaterne fra en række markforsøg, hvor man har set på eftervirkningerne af forskellige typer efterafgrøder i forhold til reduktion af nitratudvaskning, kulstofopbygning i jorden, opbygning af jordens frugtbarhed, reducering af ukrudtstrykket og dyrkningssystemet. Den rigtige brug af efterafgrøder kan derfor betyde rigtig meget for produktionen af hovedafgrøden, og i denne session vil vi gå i dybden med disse effekter

    Abstract Continuous use of cover crops including legumes showed an N yield comparable with 70 kg total N/ha/yrin manure; Nitrate leaching is mainly influenced by use of cover crops and total N inputs –not by organic vs conventional cropping; Cover crop mixtures including legumes can self-regulate N-fixation; N surplus is linked to soil carbon stock changes. Some conclusions: - continuous use of cover crops including legumes showed an N yield comparable with 70 kg total N/ha/yr in manure - nitrate leaching is mainly influcenced by use of cover crops and total N inputs - not by organic vs conventional cropping - cover crop mixtures including legumes can self-regulate N-fixation - N surplus is linked to soil carbon stock changes

    Abstract Summary: Here, we present an expanded utility of the R package qgg for genetic analyses of complex traits and diseases. One of the major updates of the package is, that it now includes Bayesian linear regression modeling procedures, which provide a unified framework for mapping of genetic variants, estimation of heritability and genomic prediction from either individual level data or from genome-wide association study summary data. With this release, the qgg package now provides a wealth of the commonly used methods in analysis of complex traits and diseases, without the need to switch between software and data formats.
    Availability and implementation: The methodologies are implemented in the publicly available R software package, qgg, using fast and memory efficient algorithms in C++ and is available on CRAN or as a developer version at our GitHub page (https://github.com/psoerensen/qgg). Notes on the implemented statistical genetic models, tutorials and example scripts are available at our GitHub page https://psoerensen.github.io/qgg/.

    Abstract We design a linear chain trick algorithm for dynamical systems for which we have oscillatory time histories in the distributed time delay. We make use of this algorithmic framework to analyse memory effects in disease evolution in a population. The modelling is based on a susceptible-infected-recovered SIR-model and on a susceptible-exposed-infected-recovered SEIR-model through a kernel that dampens the activity based on the recent history of infectious individuals. This corresponds to adaptive behavior in the population or through governmental non-pharmaceutical interventions. We use the linear chain trick to show that such a model may be written in a Markovian way, and we analyze the stability of the system. We find that the adaptive behavior gives rise to either a stable equilibrium point or a stable limit cycle for a close to constant number of susceptibles, i.e. locally in time. We also show that the attack rate for this model is lower than it would be without the dampening, although the adaptive behavior disappears as time goes to infinity and the number of infected goes to zero.

  10. Article ; Online: Extreme olfactory sensitivity of silver and bighead carp to overlapping suites of 21-carbon steroids suggests that these species, and likely all other Cyprinoidei, employ them as pheromones.

    Abstract: Although well established that several fishes including goldfish in the suborder Cypinoidei within the family Cypriniformes use the maturation-inducing steroid 17,20β-dihydroxy-pregn-4-ene-3-one (17,20βP) and its metabolites as a priming pheromone which ... ...

    Abstract Although well established that several fishes including goldfish in the suborder Cypinoidei within the family Cypriniformes use the maturation-inducing steroid 17,20β-dihydroxy-pregn-4-ene-3-one (17,20βP) and its metabolites as a priming pheromone which they detect with sensitivity and specificity, it is unclear whether and how other Cypriniformes might have evolved to do so. This study examined this question in the family Xenocyprididae. Using electro-olfactogram recording we tested the olfactory sensitivity of silver (Hypophthalmichthys molitrix) and bighead carp (H. nobilis) to a range of 213 steroids in 21 mixtures at 10
