Abstract In the present study we performed a comparative dietary analysis of two predatory birds, Long-eared Owl (Asio otus) and Common Kestrel (Falco tinnunculus) in district Lviv city. We found that are typical small mammal specialists within urban ecosystem. Considering abundance biomass prey, mammals comprise 98.4% Owl’s diet. The species composition coincides almost 50% food intake compari...

Rabies in bat-eared foxes was first recognized in South Africa in 1955 and is likely to have been derived from canine rabies introduced to South Africa in 1950. Since then it has become established in this species in the drier western half of the country and the south-western Cape so that rabies now occurs in bat-eared foxes adjacent to the peri-urban canine population of Cape Town. Peak incide...

Infrared radiation (750-1500 mmicro) produces no iris contraction in the typically nocturnal long-eared owl even when the energy content is millions of times greater than that of green light which easily elicits a pupil change. The energies in different parts of the visible spectrum required for a minimal iris response yield a spectral visibility curve for the owl which is the same as the human...

Ventral cell fates in the central nervous system are induced by Sonic hedgehog, a homolog ofhedgehog, a secreted Drosophila protein. In the central nervous system, Sonic hedgehog has been identified as the signal inducing floor plate, motor neurons, and dopaminergic neurons. Sonic hedgehog is also involved in the induction of ventral cell type in the developing somites. ptc is a key gene in the...

Objective: Recently, Red-Eared turtles are kept as pets in Iranian houses; however, because of lack of knowledge about their caring, they are in risk of lots of diseases.  Turtles of all ages should be fed with a diet that contains a wide variety of both animal and plant based items but they are usually fed by one item diet which may make gastrointestinal (GI) sickness. They are also several ba...
