• Physiological consequences of Arctic sea ice loss on large marine carnivores: Unique responses by polar bears and narwhals

      Pagano, Anthony M.; Williams, Terrie M. (2021)
      Rapid environmental changes in the Arctic are threatening the survival of marine species that rely on the predictable presence of the sea ice. Two Arctic marine mammal specialists, the polar bear (Ursus maritimus) and narwhal (Monodon monoceros), appear especially vulnerable to the speed and capriciousness of sea ice deterioration as a consequence of their unique hunting behaviors and diet, as well as their physiological adaptations for slow-aerobic exercise….
    • Semi-quantitative tests of cyanide in foods and excreta of three Hapalemur species in Madagascar

      Yamashita, N.; Tan, Chia L.; Vinyard, C.J.; Williams, C.; (2010)
      Three sympatric Hapalemur species (H. g. griseus, H. aureus, and H. (Prolemur) simus) in Ranomafana National Park, Madagascar are known to eat bamboo food parts that contain cyanide…. In this study, we tested for the presence/absence of cyanide in bamboo lemur foods and excreta to (1) document patterns of cyanide consumption among species with respect to diet, (2) identify routes of elimination of cyanide from the gastrointestinal tract, and (3) determine whether cyanide is absorbed from the diet….
