Extreme physiological adaptations as predictors of climatechange sensitivity in the narwhal, Monodon monoceros
Rapid changes in sea ice cover associated with global warming are poised to have marked impacts on polarmarinemammals.Here we examine skeletalmuscle characteristics supporting swimming and diving in one polar species, the narwhal, and use these attributes to further document this cetacean’s vulnerability to unpredictable sea ice conditions and changing ecosystems. We found that extreme morpholo...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

متن کاملWinter Feeding Intensity of Narwhals (monodon Monoceros)
Stomach contents from 121 narwhals (Monondon monoceros) harvested in the eastern Canadian High Arctic and West Greenland were used to quantify seasonal changes in feeding activity and prey selection. Stomachs collected from summer harvests were mostly empty with little evidence of recent feeding. Stomachs collected in late fall and winter harvests had considerable amounts of undigested material...
متن کاملParadoxical escape responses by narwhals (Monodon monoceros).
Until recent declines in Arctic sea ice levels, narwhals (Monodon monoceros) have lived in relative isolation from human perturbation and sustained predation pressures. The resulting naïvety has made this cryptic, deep-diving cetacean highly susceptible to disturbance, although quantifiable effects have been lacking. We deployed a submersible, animal-borne electrocardiograph-accelerometer-depth...
