Roundup: Fish in Patagonia, Film in Kashmir & Glacial Georgia

“The black southern cod, Patagonotothen tessellata, is the most important notothenioid fish species in terms of abundance in southern Chilean Patagonia. However, studies on its trophic ecology are scarce. [This study assessed] the spatial variation in the diet of P. tessellata between two localities, one with oceanic influence (Staples Strait) and another with continental influence (Puerto Bories)… The black southern cod presents spatial differences in diet composition among contrasting environmental localities… The results provide evidence of two dietary patterns depending on the type of environment in which they are distributed, highlighting the potential role of the environmental variables on the availability and abundance of potential prey and in structuring diet.”

Glaciers in the Spotlight: Salman Khan films dramatic scene at Thajwas glacier, Kashmir

“No doubt Salman Khan’s films are incredible exciting and dramatic, but his forthcoming release ‘Bajrangi Bhaijaan’ has even gotten better… ‘The Bajrangi Bhaijaan climax was shot at the base of the Thajwas glacier outside Sonamarg. Located at 10,000 feet above sea level… the 300 strong technical crew had to trek for an hour through snow every morning to reach the location. Added to this was were the 7000 extras that we had on set every day. Transporting them in hundreds of buses and then embarking on the hour-long trek was a huge logistical challenge for the production. To add to their woes was the sub zero temperatures and hail storms that would interrupt the shoot,’ said Kabir Khan who has previously worked with Salman in ‘Ek Tha Tiger.’”

“Considering its size, Georgia has a large number of glaciers. In the mountains of Georgia, there are about 786 registered glaciers, with a total area of about 550 km. About 82.5 % are in the upper courses of the Kodori, Inguri, Rioni, and Tereck rivers. For the past 150 years, significant glacier retreat (0.8–1.7 km) and shrinking of their area by 16 % has been observed. Since the middle of the 1940s, the glaciological situation has been characterized by a sharp reduction in the glacial area, but with the simultaneous increase in their number as glaciers disintegrated into separate smaller ones, although at the same time separate movements have also taken place. Avalanches are common in Georgia. Nearly 340 inhabited places are under the threat of avalanche attacks. About 31 % of the territory of Georgia is subject to avalanches (18 % in eastern and 13 % in western Georgia).”
