They can be found in botanical gardens, natural history museums, medicine and universities collections, in \u201cCabinets of curiosities\u201d or other kind of museums.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fluids collections have conservation issues that are very unique and specific, like evaporation of the solvent, airtightness, chemical and biological hazard, fragility of the container made of glass. The most specific problem is due to the discoloration of the specimen, which change the colour of the fluid used for conservation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This project will allow the UR-Arc CR to develop a research line on this kind of heritage and to elucidate the phenomenon of specimen\u2019s discoloration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PROGRAM<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The research program includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>a survey concerning the discoloration of plants in fluid, through a bibliographic review, an exchange of information with different collections curators and the observation of collections;<\/li>\n\n\n\n<li>preparation of samples using plant species more subject to discoloration, and the test of different fixatives;<\/li>\n\n\n\n<li>an analysis of the causes and the mechanisms involved in the process of discoloration.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">RESULTS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The main deliverables of the project will be :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>determine the species concerned by discoloration;<\/li>\n\n\n\n<li>understand the phenomena (causes and the mechanisms) involved in the discoloration of plant\u2019s specimens;<\/li>\n\n\n\n<li>understand the mechanism of this peculiar problem and establish the basis for the development of a research line on fluid collections that will include the evaluation of sealant materials and airtightness of the jars and methods for the maintenance of fluid collections.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">FUNDING<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Haute Ecole Arc <a href=\"https:\/\/www.he-arc.ch\/\">he-arc.ch<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PARTNERS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Botanical Museum of the University of Zurich <a href=\"https:\/\/www.bg.uzh.ch\/en.html\">bg.uzh.ch<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Botanical Garden of the University of Neuch\u00e2tel <a href=\"https:\/\/www.jbneuchatel.ch\/\">jbneuchatel.ch<\/a><\/p>\n\n\n\n<div class=\"cta-cards  \">\n\n    \n      \n        <ul class=\"flex-row mt-3 w-list-unstyled\">\n              <li class=\"size-full\">\n  \n  \n        <a href=\"https:\/\/www.he-arc.ch\/wp-content\/uploads\/oldsite\/projets\/projet_fluidis.pdf\"  class=\"cta-card is-wide is-shadowed\">\n                <div class=\"cta-card__inner is-with-arrow\">\n                <h3 class=\"cta-card__title pretty-underline is-xlarge\">PDF version<\/h3>\n        <p class=\"cta-card__description is-large\"><\/p>\n                  <span class=\"icon-arrow-right cta-card__arrow\" \/>\n              <\/div>\n        <\/a>\n    \n  \n<\/li>\n          <\/ul>\n    \n  \n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"author":8,"featured_media":20754,"template":"","he-arc_domain":[5],"he-arc_project_skill":[],"he-arc_project_year":[41,42],"class_list":["post-20891","he-arc_project","type-he-arc_project","status-publish","has-post-thumbnail","hentry","he-arc_domain-conservation-restauration","he-arc_project_year-41","he-arc_project_year-42"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>FLUIDIS \u2013 The problem of discoloration of plants preserved in fluid in botanical collections - Haute-Ecole Arc<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.he-arc.ch\/en\/projets-recherche\/fluidis\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"FLUIDIS \u2013 The problem of discoloration of plants preserved in fluid in botanical collections - Haute-Ecole Arc\" \/>\n<meta property=\"og:description\" content=\"OBJECTIVES The collections of specimens in fluids are an important part of the Natural History collections of our scientific cultural heritage.
