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...

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...

Aims. The complex Monoceros Loop SNR/Rosette Nebula region contains several potential sources of very-high-energy (VHE) γray emission and two as yet unidentified high-energy EGRET sources. Sensitive VHE observations are required to probe acceleration processes in this region. Methods. The H.E.S.S. telescope array has been used to search for very high-energy γ-ray sources in this region. CO data...

Pre-main sequence stars in the Orion-Monoceros Complex are either distributed in groups closed associated with dense cores, or dispersed along molecular filaments. Some molecular clouds are apparently affected by the OrionEridanus Superbubble created by the Wolf-Rayet winds and supernovae from the OriOB1 association, whose shock fronts compressed and triggered starbirth in adjacent molecular cl...

Bir yıllık süreyi kapsayan bu çalışmada, Kuzey Doğu Akdeniz’de dip trol balıkçılığında avlanan karides türlerinin aylar, bölgeler, sahilden uzaklık ve derinliklere göre av kompozisyonu ile verimliliklerinin belirlenmesi amaçlanmıştır. Çalışma 200 km uzunluğundaki deniz alanında belirlenen beş farklı istasyonda 40 adet operasyonu gerçekleştirilmiş toplamda 153 saat 2 dakika aktif çekimi yapılmış...
