تحلیل ابردرخت ها (Supertrees) در خانواده مگس گیریان (Aves, Muscicapidae)
آرایه شناسان به منظور حل ابهامات آرایه شناختی در سطح فراگونه ای از روش ترسیم ابردرخت ها استفاده نموده تا با ادغام کردن درخت ها در مقیاسی بزرگ به بازسازی روابط تبارزادی بپردازند. در این مطالعه به منظور ادغام تمامی درخت های مولکولی موجود و ارائه روابط کامل تبارشناختی بین افراد خانواده مگس گیریان بر روی یک درخت واحد تبارشناختی، تمامی داده های موجود برای ژن های مختلف میتوکندریایی و هسته ای در بانک ...
متن کاملComparative sequence-structure analysis of Aves insulin
Normal blood glucose level depends on the availability of insulin and its ability to bind insulin receptor (IR) that regulates the downstream signaling pathway. Insulin sequence and blood glucose level usually vary among animals due to species specificity. The study of genetic variation of insulin, blood glucose level and diabetics symptoms development in Aves is interesting because of its opti...
متن کاملJaw musculature of Cyclarhis gujanensis (Aves: Vireonidae).
Cyclarhis gujanensis is a little bird which feeds on high number of large preys, such frogs, lizards, snakes, bats and birds. As there are few studies on the cranial anatomy of this species, we aimed to describe the cranial myology to contribute to the anatomical knowledge of this species and to make some assumptions about functional anatomy. Thus, we described the muscles from the jaw apparatu...
متن کاملValidity of Bartram's Painted Vulture (Aves: Cathartidae).
William Bartram described the Painted Vulture (Vultur sacra) as a new species in his 1791 book on travels in Florida and other southeastern states. However, no specimen of this bird survives, and it has not been reported by any subsequent ornithologist. Bartram's detailed description is not presently endorsed by the American Ornithologists' Union and has been widely regarded as a myth, a misdes...
متن کاملEvolution of leaf warbler songs (Aves: Phylloscopidae)
Songs in passerine birds are important for territory defense and mating. Speciation rates in oscine passerines are so high, due to cultural evolution, that this bird lineage makes up half of the extant bird species. Leaf warblers are a speciose Old-World passerine family of limited morphological differentiation, so that songs are even more important for species delimitation. We took 16 sonograp...
