| Geological collections were established in the University of Copenhagen during the early 1700s with the presentation of fossil, mineral and rock collections by Count A.G. Moltke, mainly assembled by Ole Worm (1588-1654) in his Museum Wormianum. Currently the palaeontological collections in the Geological Museum, alone, contain over 1 million specimens, including 26,000 types. The focus of the collection remains on material from Denmark and Greenland. Highlights from Greenland include evidence of early life from the Archaean Isua Complex, the early Cambrian Sirius Passet fauna, Devonian amphibians, Triassic dinosaurs, mammals and pterosaurs, Jurassic and Cretaceous ammonites together with Jurassic and Cretaceous plants. The Danish collections are dominated... |

| Many papers on the taxonomy of fossil crustaceans are often based upon poorly preserved material and/or specimens that have been insufficiently prepared. The purpose of the present note is to outline some preparation methods that are applied in our (J.S.H. Collins and S.L.J.) ongoing studies of anomuran and brachyuran decapods from the Middle Danian limestones at Fakse quarry (Denmark), which have greatly enhanced the quality of our material. The techniques briefly outlined here involve: 1 – staining method; 2 – water blasting (as a cleaning tool in preparation of fossils); and 3 – negative preparation (with acid). Some of these techniques will have wide applications in other fields of paleontological research. |

| Præsentationen viser at størstedelen af de økologiske bedrifter - i lighed med de konventionelle - er specialiserede med en dominerende produktionsgren. Ligeledes er der også en regional specialisering hvor planteproduktionen er helt dominerende i Østdanmark, men Vestdanmark har en mere blandet sammensætning af bedriftstyper, i relation til antal. På amtsniveau er der en koncentration af økologiske bedrifter især i Sønderjylland men også i vestjyske amter og Hovedstadområdet. I en større geografisk opløsning er der stor interregional variation i tætheden, men Sønderjylland står fortsat ud som en region med stor overgennemsnitlig koncentration. Lokale processer spiller tilsyneladende en betydende rolle i omlægningen. |

| Ud fra data fra Kvægdatabasen har vi lavet en analyse af, hvilke forhold på besætningsniveau der viser sammenhæng til forekomsten af leverbylder. Resultaterne viser, at besætninger med lave fedtprocenter i tankmælk og med store svingninger i fedt- og proteinprocenter gennem året har en højere forekomst af leverbylder. Der var ingen sammenhæng mellem årsydelsen i kg EKM og forekomsten af leverbylder. Økologiske besætninger havde generelt en lavere fedtprocent end konventionelle besætninger. |

| Moderne staldgødningsspredere opererer med langt større arbejdsbredder end tidligere og er i stand til at sikre en jævnere spredefordeling af fast husdyrgødning, end set for ældre modeller. De testede typer er alle i stand til at sikre en ensartet spredning af både frisk og lagret dybstrøelse, forudsat at arbejdsbredden ikke overstiger en given afstand. Staldgødningsspredere udstyret med et tallerkenspredesystem giver, forudsat brug af større traktorkraft, mulighed for større arbejdsbredde og kapacitet end staldgødnings-spredere udstyret med et spredesystem, bestående af to opretstående spredevalser. Staldgødningsspredere udstyret med et tallerkenspredesystem har til gengæld et relativt større energibehov. |

| Noten er et sammendrag af resultater fra delprojektet "Localisation of organic farms" under Nature Quality in organic farming. Det vises at mens hovedparten af de danske økologiske bedrifter er specialiserede, er der i Jylland antalsmæssigt ikke tale om en voldsom specialisering, mens Fyn og Sjælland er stærkt domineret af planteavlere. Koncentration og spredningsmønstre vises for 1994 og 2001, og der konstateres en tendens til lokal spredning. |

| A grazing study was performed in 2006 over three two-week periods in May, June and August at the organic research station Rugballegaard, Denmark, where a herd of 48 Holstein dairy cows was split into four groups of 12 cows. Each group grazed one of four swards: 1) lucerne, 2) red clover, 3) white clover and 4) white clover with chicory, all four in mixture with perennial ryegrass. Milk and grass samples were analyzed to study the effect of each sward type on milk composition as well as seasonal variations. |

| It is important that children are provided with a solid foundation for making sound decisions in relation to health and that health aspects be incorporated into their daily life. In this connection, public schools are important health promoting platforms due to their potential for encouraging interest, knowledge and learning about health related issues. The central idea for the study has been to address pupil perceptions and not merely to emphasise a narrow professional approach. In order for health initiatives, offered in connection with public schools, i.e. initiatives aimed at the available food selection and class room teaching, to impact children's day-to-day health, the basic assumption has been that pupils must see the initiatives as relevant.... |

| The FASSET farm model was used to simulate production in an experiment where a grass-clover or a grass ley was either cut or grazed with dairy cows receiving low or high N sup-plements. The six different ley types were ploughed in and followed by three years with spring cereals with undersown catch crops. The original model was extended with a new grass and clover model, which included the capability to simulate rhizodeposition and root growth. The new model predicted the observed annual carbon (C) and nitrogen (N) production satisfactorily. The simulated first year residual effects of a cut grass or grass-clover ley varied between 0 and 34, while the residual effect of a grazed grass or grass-clover ley varied between 71 and 150 fertilizer equivalents... |

| This paper presents the findings of an assessment aimed to evaluate, in terms of cost and energy consumption, the introduction of living mulches in different organic vegetable systems producing cauliflower. The study was carried out in three European countries (IT, SLO and DK) in the frame of the InterVeg project (Core Organic II). The achievements demonstrated that, in economic terms, farmers’ choice of a specific technique, like living mulch instead of sole cropping, can be influenced by two key elements: human labor and fossil fuel consumption. Different organic systems have a different proportion in using the two inputs depending on the specific farm strategy. |

| Høje foderpriser giver de økologiske mælkeproducenter et fald i indtjeningen i 2012. Driftsresultatet er dog fortsat bedre end hos deres konventionelle kollegaer. Et højt markedstillæg giver svineproducenterne et flot resultat, på trods af høje foderpriser. Fuldtidsplanteavlerne har trods høje priser et fald i indtjeningen. Stigningen i bruttoudbyttet var lavere end stigningen i omkostningerne. Deltidsplanteavlerne har forbedret resultatet, der dog fortsat er negativt. Højere priser kompenserer for et lavere udbytte, men ikke for økologernes højere andel af kløvergræs og vedvarende græs i sædskiftet. |

| This new overarching research and development strategy has been prepared by the programme committee at ICROFS in 2012. It describes the areas where a research effort would benefit the industry and also its importance to society. Research and development strategy 2012 is the result of a long hearing process, where stakeholders within and associated with the organic sector were given the opportunity to present their views on existing development potentials and barriers and where research and development activities will be able to make a difference. It has led to hoth new ideas and greater visions, which the sector believes are essential to ensure leaps in knowledge and development. The process has also uncovered very specific barriers and problems that... |

| High mortalities among rainbow trout (Oncorhynchus mykiss) fry are often the result of infections caused by Flavobacterium psychrophilum, and in Denmark this pathogen can be found in nearly all freshwater fish farms. The infection can be treated with antibiotics, but lower sensitivity against the infection is an increasing problem for some of the used drugs, wherefore alternative treatment methods (e.g. bacteriophages) are investigated. Prophylactic measures (e.g. feed additives) are another approach, so infections with the bacterium can be avoided, before they become a problem. No matter if the focus is on prophylactic or alternative treatment, reliable infection models are needed to evaluate the treatments as well as to get more knowledge about... |
