Many P-element insertions affect wing shape in Drosophila melanogaster.

A screen of random, autosomal, homozygous-viable P-element insertions in D. melanogaster found small effects on wing shape in 11 of 50 lines. The effects were due to single insertions and remained stable and significant for over 5 years, in repeated, high-resolution measurements. All 11 insertions were within or near protein-coding transcription units, none of which were previously known to aff...

Wing shape variation associated with mimicry in butterflies.

Mimetic resemblance in unpalatable butterflies has been studied by evolutionary biologists for over a century, but has largely focused on the convergence in wing color patterns. In Heliconius numata, discrete color-pattern morphs closely resemble comimics in the distantly related genus Melinaea. We examine the possibility that the shape of the butterfly wing also shows adaptive convergence. Fir...

Wing coloration and pigment gradients in scales of pierid butterflies.

Depending on the species, the individual scales of butterfly wings have a longitudinal gradient in structure and reflectance properties, as shown by scanning electron microscopy and microspectrophotometry. White scales of the male Small White, Pieris rapae crucivora, show a strong gradient in both the density in pigment granules and the reflectance. After pigment extraction by aqueous ammonia, ...

Sexual dimorphism in the wing shape and size of the carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae)

پروانه‌ی کرم گلوگاه انار، Ectomyelois ceratoniae (Zeller) ، به خانواده‌ی Pyralidae و زیر خانواده‌ی Phycitinae تعلق دارد. علیرغم وجود شواهدی دال بر وجود اختلاف شکل و اندازه در جنس‌های نر و ماده‌ی بسیاری از پروانه‌ها و همچنین در اعضای این خانواده، وجود چنین اختلافی تاکنون در گونه‌ی مورد بحث گزارش نشده است. در تحقیق حاضر، دوشکلی جنسی در اندازه و شکل بال پروانه‌ی کرم گلوگاه انار روی چهار میزبان انا...

Robust MRAC for a Wing Rock Phenomenon in Delta Wing Aircrafts

Wing rock phenomenon is an undesired motion appears in high angles of attack where a rolling in the aircraft in positive and negative roll angles with specified amplitude and frequency is occurred. In this paper two adaptive controllers suggested to control the rolling dynamics under wing rock phenomenon for a delta wing aircraft with presence of disturbance. Disturbance was considered as unmat...
