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 کاملAssociações entre as biomassas de peixes Sciaenidae (Teleostei: Perciformes) e de camarões Penaeoidea (Decapoda: Dendrobranchiata) no litoral norte do Estado de São Paulo
To study the relationships among Sciaenidae fish and Penaeoidea shrimp biomass, fieldwork was carried out in the north coast of São Paulo state, Brazil, during the four seasons of 2001. Samples were collected in transects from different depths at Ubatuba, Caraguatatuba, and São Sebastião cities. Water and sediment were collected from each transect. The hypotheses that the environmental factors ...
متن کاملLadies and gentes: maternally inherited DNA and ancient honeyguide host races.
A vian interspecific brood parasitism occurs when a female bird uses a different host species to incubate and rear her offspring. Studies of this parasitic behavior have provided some of nature’s most compelling examples of coevolutionary interactions (1). Avian brood parasites exhibit wide variation in host specificity, ranging from one or a few hosts to hundreds, and there is a concomitant de...
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...
