Voucher specimens are those <br />collected and preserved from a specific location at a specific time and as such represent a <br />historical natural occurrence or sample of natural history. Most UCRB collections held by <br />LFL are voucher collections. Such collections are stored on shelving according to container <br />size (usually vials in trays on upper shelves and a mix of larger containers on lower <br />shelves) and ordered serially within either of those two groupings by catalog number. <br />When possible, all lots from the same collection and all collections from the same <br />collecting event or investigation are cataloged and stored together in sequence (except for <br />storage separation according to container size). Study collections consist of specimens that <br />lack associated collection location or date information or were artificially reared, preserved <br />during or at the conclusion of laboratory or field experiments, or selectively and <br />permanently removed from voucher collections for morphological examination, descriptive <br />study, or other educational or research purposes. Reference collections are special subsets <br />of these that are conveniently organized for routine comparison with collected material to <br />aid taxonomic identification. Study and reference specimens are stored separately from <br />voucher material and are organized according to more standard museum practice, first <br />phylogenetically (by species), then by catalog number. <br />To facilitate organization of cataloged collections on LFL shelving and minimize <br />evaporative losses, we have standardized containers to 20-ml glass scintillation vials with <br />Polysealâ„¢ caps, and 2, 8, and 16-oz straight-sided jars (83, 134, and 147-mm tall, <br /> <br />11 <br />
