Genetic diversity in isolated patches of the tallgrass prairie forb, Lithospermum canescens (Boraginaceae). J. Torrey Bot. Soc. 133: 513–518. 2006.—Genetic diversity is not well understood for many species inhabiting isolated, fragmented systems. We evaluated genetic diversity for the mix...

BACKGROUND A well functioning Health Information System (HIS) is crucial for effective and efficient health service delivery. In Tanzania there is a national HIS called Mfumo wa Taarifa za Uendeshaji Huduma za Afya (MTUHA). It comprises a guideline/manual, a series of registers for primary data collection and secondary data books where information from the registers is totalled or used for calc...

A real-life morphological analyzer must be able to handle properly the out-of-vocabulary words. We address the task of guessing the correct inflectional paradigm of unknown Croatian words. We frame this as a supervised machine learning problem: we train a model for deciding whether a candidate lemma-paradigm pair is correct based on a number of stringand corpus-based features. Our aim is to exa...

Arctic and alpine, high latitude elevation environments are one of the most stressful for species to inhabit. This harshness manifests itself in lower richness comparison more southern vegetation zones (Francis & Currie, 2003). Furthermore, climatic oscillations—past predicted—have dramatic effect on these ecosystems. For example, regions continental ice sheets—the northernmost part Western Eur...

Sulforaphane (SFN) is an isothiocyanate which is produced through glucoraphanin hydrolysis via myrosinase activity. In the present study, SFN content and peroxidase activity has been assessed in treated Lepidium draba seedlings with different concentrations of iron and copper during 8 and 16 hours treatment. The results showed that the SFN content drastically elevated at treatment with...

After heavy rainfalls in late Apr. of 2010 in Tehran, an epizootic occurred amongst hoverflies (Eupeodes corollae Fabricius) population in green spaces of Iranian Research Institute of Plant Protection, caused by an entomopathogenic fungus. Infected flies fixed to the upper parts of whitetop (Lepidium draba L.) and small tumbleweed mustard (Sisymbrium loeslii L.) plants with their proboscis and...
