    Groenekennis - Informatie voor professionals in voedsel en groen

    Groenekennis bevat artikelen uit vaktijdschriften, rapporten, video’s, presentaties, posters en websites op het gebied van landbouw, visserij, groene ruimte en voeding. Groenekennis wordt dagelijks bijgewerkt en bevat ongeveer 500.000 bronnen.

    Groenekennis is de globale view over diverse deelbestanden. Groenekennis is gevuld met alle informatie uit Groen Kennisnet, de Hydrotheek, Tuinpad, IB archief, ARTIK, bioKennis, Kennisbank Plantaardige bronnen, Kennisbank Zeldzame landbouwhuisdieren en afgesloten documentatiebestanden zoals Land Bodem Water en Consumenten- en huishoudstudies.

    Groen Kennisnet is een zeer belangrijk onderdeel van Groenekennis. De doelstelling van Groen Kennisnet is kennis delen op het gebied van Voedsel en Groen te bevorderen en te faciliteren voor een breed publiek.

    Bronnen in Groenekennis kunnen direct opgevraagd worden via een geavanceerde zoekmachine met een 'google-achtige' interface. Met filters kan ingezoomd worden op diverse aspecten, zoals Trefwoord, Collectie, Jaar en Auteur. Bovendien biedt Groenekennis gebruikers de mogelijkheid om via de E-mail geattendeerd te worden op aanvullingen in specifieke vakgebieden.
    De Tijdschriftenlijst biedt een overzicht van tijdschriften waaruit de artikelen voor Groenekennis worden geselecteerd. Door te klikken op een titel krijgt u alle artikelen uit dat tijdschrift in de Groenekennis database getoond.
    Zoeken op kaart biedt een geografische ingang op de beschikbare publicaties over de binnen dit bestand onderscheiden gebieden.

    Groenekennis is onderdeel van het bibliotheeksysteem van WUR. Praktijkgerichte publicaties en rapporten van WUR komen daardoor automatisch beschikbaar. Daarnaast wordt de database doorlopend gevuld met voor het groen onderwijs bruikbare bronnen en artikelen, video’s en websites. Het percentage online is de laatste jaren gegroeid tot tweederde van de totale aanwas per jaar. Dit percentage groeit nog steeds.

Animal breeding : the concept of inbreeding [Video]
Bijma, P. \ 2019
Inbreeding is the result of mating two related individuals. Related individuals are more alike genetically than non-related individuals because they share alleles.

Wat is erfelijkheid? \ Zeldzaam huisdier : tijdschrift van de Stichting Zeldzame Huisdierrassen [Artikel]
Maurice-van Eijndhoven, M. \ Oldenbroek, K. \ 2015
Eigenschappen van dieren zijn in meer of mindere mate erfelijk. Ze gaan over van ouders op nakomelingen. Maar ervaren fokkers weten dat in de fokkerij 1+1 geen 2 is. Welke wetmatigheden en welke toevalligheden spelen een rol in de erfelijkheid? Wat h ...

Population differentiation as a test for selective sweeps \ Genome research [Artikel]
Chen, H. \ Patterson, N. \ Reich, D. \ 2010
Selective sweeps can increase genetic differentiation among populations and cause allele frequency spectra to depart from the expectation under neutrality. We present a likelihood method for detecting selective sweeps that involves jointly modeling t ...

Amador, C. \ Toro, M.A. \ Fernández, J. \ 2010
Loss of genetic diversity reduces species ability to adapt to new environments and causes decreases in fitness. The benefits of the interchange of genetic resources are known and widely used among livestock. Nevertheless, sometimes a new input of gen ...

Molecular characterization of breeds and its use in conservation \ Livestock science [Artikel]
Toro, M.A. \ Fernandez, J. \ Caballero, A. \ 2009
The conservation of farm animal resources is important for coping with future breeding needs and for facilitating the sustainable use of marginal areas. The increasing availability of molecular markers for most farm animal species and the development ...

Genetics of intra-gene pool and inter-gene pool hybridization for seed traits in common bean (Phaseolus vulgaris L.) germplasm from Europe \ Field crops research : an international journal [Artikel]
González, A.M. \ Rodiño, A.P. \ Santalla, M. \ Ron, A.M. de \ 2009
Due to adaptation to new ecological and manmade conditions, the large diversity evolved in the European common bean germplasm is of particular interest for plant breeding. The knowledge of the genetic relationships within and among races and gene poo ...

Multiscale analysis reveals restricted gene flow and a linear gradient in heterozygosity for an island population of feral horses \ Canadian journal of zoology = Journal canadien de zoologie / National Research Council of Canada [Artikel]
Lucas, Z.L. \ McLoughlin, P.D. \ Coltman, D.W. \ Barber, C. \ 2009
We studied the genetic (microsatellite) diversity of a feral population of horses (Equus caballus L., 1758) on Sable Island, Nova Scotia, Canada (1983-2003), at two spatial scales: (1) for the island as a whole and (2) at the level of four equally si ...

Evidence for a breed specific association between PrP genotype and ultrasonic muscle depth but not for survivability, growth or carcass traits in sheep \ Livestock science [Artikel]
Hanrahan, J.P. \ Casey, K.C. \ Sweeney, T. \ 2008
The ARR allele of the prion protein gene is associated with resistance to classical scrapie, while the ARQ allele is associated with susceptibility. The objective of this study was to estimate the effect, on lamb growth and carcass traits, of replaci ...
