An electrophoretic approach to the systematics of Italian gulls and terns (Aves, Laridae and Sternidae)

摘要: SUMMARY The systematics of Lari (Aves Charadriiformes) has been extensively studied on the basis biometrical, ethological and external morphological characters; yet no conclusive results have achieved by different authors. Another point discussion is raised phylogenetic relationships among many species belonging to families Laridae Sternidae, with a very important adaptive radiation, now showing extremely dynamic demographic trends (ample fluctuations in tern population, quick expansion gull species). «Progetto Laridae» provided useful information population estimates, colony structure, dynamics 10 breeding Italy. On this we undertook an electrophoretic analysis blood proteins enzymes, attempt solve problems Italian using methods molecular biology, only rarely used when studying group. Blood samples from approximately 260 chicks five Laridae: La...
