the cecidomyiid species rabdophaga heterobia (loew) induces gall on willow's male catkins, and causes small rosettes at the extremities of shoots and swollen lateral buds or lateral rosettes on some species of willow. during the years 2006-2007, a study on willow pests in the west azarbaijan province (saatloo poplar research station) was conducted. the following nine willow species were us...

Willow is an important biomass crop for the bioenergy industry, and therefore optimal growth with minimal effects of biotic and abiotic stress is essential. The phenylpropanoid pathway is responsible for the biosynthesis of not only lignin but also of flavonoids, condensed tannins, benzenoids and phenolic glycosides which all have a role in protecting the plant against biotic and abiotic stress...

Introduction The Willow architecture provides a comprehensive architectural approach to the provision of survivability [8] in critical information networks. It is based on the notion that survivability of a network requires reconfiguration at both the system and the application levels. The Willow notion of reconfiguration is very general, and the architecture provides reconfiguration mechanisms...

The distribution characteristics of willow (genus Salix) can be evaluated with the use of remote sensing, geographic information systems (GIS) technologies, and spatial analysis. This information can be used to better understand willow ecology, such as willow community composition, species relationships, and associations with other landscape attributes (i.e., soils, elevation gradients, water s...

We explore the potential of making programmability a central feature of the SSD interface. Our prototype system, called Willow, allows programmers to augment and extend the semantics of an SSD with application-specific features without compromising file system protections. The SSD Apps running on Willow give applications lowlatency, high-bandwidth access to the SSD’s contents while reducing the...

After an absence of approximately 70 years, gray wolves (Canis lupus) were re-introduced into Yellowstone National Park in the mid-1990s. We studied the potential influence of wolf/ungulate interactions upon willow (Salix spp.) growth in the valleys of the Gallatin and Lamar Rivers, as well as Slough and Soda Butte Creeks, in the northern Yellowstone ecosystem. When we compared willow heights f...

To elucidate the adsorption property and the mechanism of plant residues to reduce oxytetracycline (OTC), the adsorption of OTC onto raw willow roots (WR-R), stems (WS-R), leaves (WL-R), and adsorption onto desugared willow roots (WR-D), stems (WS-D), and leaves (WL-D) were investigated. The structural characterization was analyzed by scanning electron microscopy, Fourier-transform infrared spe...

Trees can improve air quality, but at the same time, pollution might put them at risk. Plane(Platanus orientalis L) and willow trees (Salix babylonicaL) are important trees in the green space of Tehran. Plane trees in Tehran have experienced early autumn in recent years due to severe air pollution. The present study, investigated some physiological traits of these trees under study to determine...

A primary constraint on effective conservation of migratory animals is our inability to track individuals through their annual cycle. One such animal is the endangered southwestern subspecies of the Willow Flycatcher, which is difficult to distinguish from conspecifics. Identifying wintering regions used by the endangered subspecies would be an important step in formulating an effective conserv...
