The important intracellular oxygen-binding protein, myoglobin (Mb), is thought to be absent from oxidative muscle tissues of the family of hemoglobinless Antarctic icefishes, Channichthyidae. Within this family of fishes, which is endemic to the Southern Ocean surrounding Antarctica, there exist 15 known species and 11 genera. To date, we have examined(More)
We determined the myoglobin cDNA sequence for seven Antarctic notothenioid fish species. These data identify mutations in the myoglobin gene for Champsocephalus gunnari and Pagetopsis macropterus, two icefish species that lack detectable quantities of the polypeptide but express myoglobin mRNA. a third species lacking myoglobin polypeptide, Chaenocephalus(More)
Registration is one of the most difficult problems in augmented reality (AR) systems. In this paper, a simple registration method using natural features based on the projective reconstruction technique is proposed. This method consists of two steps: embedding and rendering. Embedding involves specifying four points to build the world coordinate system on(More)
Herbivorous vertebrates rely on complex communities of mutualistic gut bacteria to facilitate the digestion of celluloses and hemicelluloses. Gut microbes are often convergent based on diet and gut morphology across a phylogenetically diverse group of mammals. However, little is known about microbial communities of herbivorous hindgut-fermenting reptiles.(More)
In AR systems, registration is one of the most difficult problems currently limiting their application. In this paper, we propose a simple registration method using projective reconstruction. This method consists of two steps: embedding and tracking. Embedding involves specifying four points to build the world coordinate system on which a virtual object(More)
A subtidal seaweed collected in antarctic waters, Plocamium cartilagineum (L. Dix.), displayed induction of mRNAs encoding the 70 kDa heat shock protein (HSP70) and the ubiquitin polyprotein (UBI) when incubated at 5 degrees C. Maximal induction of HSP70 mRNA was observed when the alga was incubated at 10 degrees C for 1 h. Incubations at higher(More)
Research on the genetics of natural populations was revolutionized in the 1990s by methods for genotyping noninvasively collected samples. However, these methods have remained largely unchanged for the past 20 years and lag far behind the genomics era. To close this gap, here we report an optimized laboratory protocol for genome-wide capture of endogenous(More)
