Geographic information systems (GIS) are powerful tools for investigating the ecogeography of environmentally acquired infections. GIS technology was used to geocode and map cases of blastomycosis, by household, of human and dog residents of Vilas County, Wisconsin, USA. Human case households (n = 136) were from a comprehensive street address registry 1979--2001; human controls were 200 random-...
At least 250 cave burials along the Meuse river basin of Belgium yield prehistoric remains, and most date from Late Neolithic period. Several have been radiocarbon dated, including early/late deposits Hastière Caverne M Trou Garçon C final/late caves Sclaigneaux Bois Madame. An additional collective burial, Maurenne de la Cave is dated to Middle periods, circa 4,635 3,830 BP, encompassing range...
Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding. Geographic occurrence, bioclimatic, and biophysical data were used to predict species distributions, range overlap and niche occupancy in 36 taxa closely related to sunflower (Helianthus annuus L.). Taxa lacking com...
Although great accomplishments of in situ conservation have been made during the last decade throughout the world, there is an urgent need to conduct more targeted research to explore many basic questions about crop wild relatives (CWR) in situ conservation such as how to better identify and manage the target in situ conservation populations of CWR. In this study, we performed an extensive fiel...
Chickpea (Cicer arietinum L.) is a major pulse crop in the Indian subcontinent and other world regions and is characterized by narrow adaptation relative to other cool season food legumes. Comparative ecophysiology employing closely related wild species is a powerful tool to broaden the understanding of the genetic and physiological basis of crop adaptation. However, meager data are available o...
در این بررسی، 30 نمونه (6 جمعیت) از گونههای بال بلند بخشه Onobrychis از جنسMill. Onobrychis شامل گونههای O. verae Širj., O. gontscharovii Vassilcz., O. ptychophylla Širj. & Rech. f., O. sosnovskyi Grossh. و O. araxina Schischkin، از زیستگاه‌های طبیعی خود در ایران جمع‌آوری شدند. این نمونهها با استفاده از 45 ویژگی کمی و 15 ویژگی کیفی مورفولوژیکی مورد ارزیابی قرار گرفتند. به منظور بررسی تنوع ژ...
