— Most of the literature on natural history is hidden in millions of pages stacked up in our libraries. Various initiatives aim now at making these publications digitally accessible and searchable, applying xmlmark up technologies. The unique biological names play a crucial role to link content related to a particular taxon. Thus discovering and marking them up is extremely important. Since the...

To explore the biosystematics of the Calligonum mongolicum complex (Polygonaceae), the flowering phenological period, breeding and pollination characters and seed set of the complex (Calligonum Mongolicum Turze, Calligonum chinense A. Los., Calligonum gobicum A. Los., Calligonum pumilum A. Los. and Calligonum zaidamense A. Los.) were documented in the Turpan Eremophyte Botanical Garden, China. ...

BACKGROUND The history of domestication of artichoke and leafy cardoon is not yet fully understood and when and where it occurred remains unknown. Evidence supports the hypothesis that wild cardoon is the wild progenitor of both these crops. Selection for large, non-spiny heads resulted in artichoke and selection for non-spiny, large stalked tender leaves resulted in leafy cardoon. The two crop...

Although the cattail mosquito, Coquillettidia perturbans (Walker) is found in North America (north of Mexico) throughout most of the United States and southern Canada, its distribution in the Rocky Mountain States is not well known and only a few collection records have been reported (Darsie and Ward 2005) (Figure 1 [inset]). Since its discovery in Idaho in Latah County (Stage et al. 1952), all...

Research on arbuscular mycorrhizal fungi (AMF), presently, is at the crossroads. Some aspects like their beneficial role in overall plant growth under diverse edaphic conditions, have been thoroughly investigated and further, there is no second opinion to the advocacy of their development as bioinoculants. However, the biosystematics, culturability and field performance evaluation of this group...

The biodegradation of aromatic hydrocarbons by fungi has traditionally been considered to be of a cometabolic nature. Recently, however, an increasing number of fungi isolated from air biofilters exposed to hydrocarbon-polluted gas streams have been shown to assimilate volatile aromatic hydrocarbons as the sole source of carbon and energy. The biosystematics, ecology, and metabolism of such fun...

During an ongoing survey of the ectoparasites of birds in Canada (Bourgeois and Threlfall, 1981, Proc. Entomol. Soc. Wash. 83: 799-800; Eveleigh and Threlfall, 1974a, Proc. Entomol. Soc.
