Adelie Penguenleri: Uydu G\u00f6r\u00fcnt\u00fcleri Koloni Boyutunu ve Beslenme Al\u0131\u015fkanl\u0131klar\u0131n\u0131 Ortaya Koyuyor<\/h2>\n\n

NASA taraf\u0131ndan fonlanan ara\u015ft\u0131rmac\u0131lar, D\u00fcnya’daki en iyi bilinen ve en az gizemli hayvanlardan biri olan Adelie penguenlerini incelemek i\u00e7in uydu g\u00f6r\u00fcnt\u00fclerini kullan\u0131yor.

Guano Koloni Boyutunu Ortaya Koyuyor<\/h2>\n\n

Uydu g\u00f6r\u00fcnt\u00fcleri bireysel penguenleri g\u00f6stermez, ancak parlak pembe guano lekelerini tespit ederek koloninin boyutunu ortaya \u00e7\u0131karabilirler.<\/p>\n\n

Stony Brook \u00dcniversitesi’nde bir ekolog olan Heather Lynch, “Guano lekesiyle tan\u0131mlanan koloni alan\u0131n\u0131 kullanarak, koloni i\u00e7inde olmas\u0131 gereken \u00e7ift say\u0131s\u0131na kadar geri d\u00f6nebiliriz” diyor.<\/p>\n\n
