• species
  • The Smithsonian's National Museum of Natural History houses Martha, the last passenger pigeon and a some collections still have Great Auk specimens, a bird species that went extinct in 1844. (wikipedia.org)
  • The primary justification for including digital images was to: Give researchers remote visual access to thylacine specimen material and to the accompanying data thus encouraging and promoting continued research into the species. (wikipedia.org)
  • adult
  • Excluding exceptionally large specimens, adult alligator snapping turtles generally range in carapace length from 35 to 80.8 cm (13.8 to 31.8 in) and weigh from 8.4 to 80 kg (19 to 176 lb). (wikipedia.org)
  • Research
  • Research into improved methods of presentation and handling continues, each requiring its own equipment. (wikipedia.org)
  • The International Thylacine Specimen Database (ITSD) is the culmination of a four-year research project to catalogue and digitally photograph all known surviving specimen material of the thylacine (Thylacinus cynocephalus) (or Tasmanian tiger) held within museum, university, and private collections. (wikipedia.org)
  • adequate
  • M. B. Cohen, M. S. Soloway, and W. M. Murphy, "Sampling of radical prostatectomy specimens: how much is adequate? (hindawi.com)
  • This standard pin length is sufficient to accommodate an adequate number of data labels and to permit convenient handling with suitably curved forceps. (wikipedia.org)
  • known
  • The smallest known specimens measure around 350mm. (wikipedia.org)
  • Proper hand washing after handling should prevent any problems with ingestion of tetrodotoxin (as well as infection from Salmonella which newts may carry), though some individuals are known to be allergic to skin contact with the toxin. (wikipedia.org)
  • small
  • Subject: Small cytologic specimen handling recommendations Can anyone recommend materials and methods or products for processing small specimens of loosely aggregated cells? (histosearch.com)
  • Even if stained, these can be very difficult for the histotechs to see the specimens, which are small and blend in with the paraffin, and therefore difficult to determine how far to section into the block. (histosearch.com)
  • Specimen should be collected in small (15-25 ml.) conical/test tube or as smears. (micropathlabs.com)
  • A notable occurrence is the old Mammoth-Saint Anthony Mine near Mammoth, Arizona where small crystals that make fine micromount specimens are found. (wikipedia.org)
  • form
  • Also, rough-skinned newts' upper teeth form a V shape, while those of the California newt form a Y shape, but this is difficult to ascertain on a living specimen. (wikipedia.org)
  • support
  • When specimens are mounted on a smaller support which in turn is supported on a normal full-sized entomological pin, this is called staging. (wikipedia.org)
  • To support the data component and to significantly enhance its educational worth, high-resolution digital images of the specimens are included. (wikipedia.org)
  • unique
  • The International Thylacine Specimen Database is a unique and precise database of the largest modern day marsupial carnivore. (wikipedia.org)
  • necessary
  • It is often necessary to X ray specimen slices to localise calcs precisely to guide block selection. (breastpathology.info)
  • If appropriate the tip of the point may be bent at the necessary angle to hold the body of the specimen horizontal when the pin is vertical, with the long axis of the insect at right angles to the point. (wikipedia.org)
  • blood
  • Used for blood culture specimens or acid-citrate-dextrose (ACD), used for blood bank studies, HLA phenotyping, and paternity testing. (wikipedia.org)
  • length
  • Play media In "mature" specimens (carapace length over 30 cm (12 in)), males and females can be differentiated by the position of the cloaca from the carapace and the thickness of the tail's base. (wikipedia.org)
  • record
  • Assist with the security of source material in that a photographic record exists for all specimens within the database. (wikipedia.org)
  • collections
  • Specimens of the thylacine are spread extensively around the globe so the search to locate these specimens was from the outset an international search involving a total of 106 museum, university and private collections in 23 countries. (wikipedia.org)
