Top predators may induce extensive cascading effects on lower trophic levels, for example, through intraguild predation (IGP). The impacts of both mammalian and avian top predators on species of the same class have been extensively studied, but the effects of the latter upon mammalian mesopredators are not yet as well known. We examined the impact of the predation risk imposed by a large avian ...

Eagle syndrome is an aggregate of symptoms caused by an elongated styloid process, most frequently resulting in headache, facial pain, dysphagia and sensation of foreign body in throat. The proper diagnosis is not difficult with clinical history, physical examination and radiographic assessment if there is a sufficient degree of suspicion. The treatment is very effective. We report here a typic...

introdouction:the styloid process(sp) has the potential for calcification and ossification. the aim of this study was to investigate the prevalence of different patterns of elongation and calcification of the sp. materials and methods: in this cross-sectional study, 400 digital panoramic radiographs taken for routine dental examination in the dental school of shiraz university were evaluated fo...

This paper presents the design and performance of Evolved Acceleration Guidance Logic for Entry (EAGLE), an algorithm intended for future space transportation vehicles. The most distinguishing feature of EAGLE is its ability to plan a three-dimensional trajectory and thereby handle large crossrange entries. EAGLE consists of two integrated components: a trajectory planner and a tracking law. Th...

During development of the Drosophila nerve cord, neuroblast 7-3 gives rise to a pair of mitotic sister serotonin neurons in each hemisegment. Here we show that the zinc finger gene eagle, which is expressed in neuroblast 7-3, is essential for specifying the fate of serotonin neurons. We find that loss-of-function eagle mutations produce an unusual differential phenotype with respect to the sist...

The short-toed eagle (Circaetus gallicus) is a trophic specialist with a diet based almost exclusively on ophidians. In this work, the distribution of this eagle in southeastern Spain taken from national atlases, is analysed in relation to environmental variables. The results show that the short-toed eagle is distributed primarily in shrublands, probably because there it can easily locate and c...
