• Attempted Predation by Nigeria-Cameroon Chimpanzees (Pan troglodytes ellioti) on Preuss's Red Colobus (Procolobus preussi) in the Ebo Forest, Cameroon

      Morgan, Bethan J.; Suh, J.N.; Abwe, Ekwoge E. (2012)
      We describe the first observation of a predation attempt by Nigerian-Cameroon chimpanzees (Pan troglodytes ellioti) on Preuss’s red colobus (Procolobus preussi) in the Ebo forest, Cameroon. The activity, which was observed for 15 min, primarily involved 1 chimpanzee and 1 red colobus individual, with a further 2 chimpanzees observing the event....
    • 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….
    • Rusty-gray lesser bamboo lemur (Hapalemur meridionalis). The IUCN Red List of Threatened Species.

      Donati, Giuseppe; Balestri, M.; Campera, M.; Eppley, Timothy M. (International Union for Conservation of Nature, 2020)
      There is a suspected population reduction of >=30% in this species over a three generation period. Causes of this reduction (which have not ceased) include continuing decline in area, extent and quality of habitat, and exploitation through hunting. Between 1999-2005 habitat loss in the Tsitongambarika Protected Area has been 1.74% per year (Andriamasimanana 2008). A population reduction of ?30% is also suspected to be met in the next 27 years (over a three generation time period) due to the same causes. These causes have not ceased, and will to a large extent not be easily reversible. Of note, it has been estimated that there will be a 21% reduction in the species' range from 2000 to 2080 due to climate change alone (Brown and Yoder 2015). Based on these premises, the species is listed as Vulnerable....
