Abstract The study of seed dispersal, biotic and even less, the role birds in it, have been almost neglected deserts. Virtually absent from literature on dispersal are ground-jays, genus Podoces , four species crow family that inhabit arid environments, true deserts, Iran to Mongolia. Although they omnivorous, seem mainly depend seeds desert plants during cold season. There suggestions sparse m...

The aim of the article is to evaluate time availability food stores for population permanently residing in city Nitra (Slovakia). Parts where poor accessibility has been identified can be described as “food deserts”. In last two decades, there have dramatic changes retail network Nitra, well extensive housing construction and an aging change demographic structure. Therefore, we evaluated years ...

BACKGROUND Food access is a global issue, and for this reason, a wealth of studies are dedicated to understanding the location of food deserts and the benefits of urban gardens. However, few studies have linked these two strands of research together to analyze whether urban gardening activity may be a step forward in addressing issues of access for food desert residents. METHODS The Phoenix, ...

Following their fall to Earth, meteorites experience weathering. In this systematic study, we evaluate the trace element composition of ordinary chondrites from Antarctic cold desert, and Atacama (Chile) Lut (Iran) hot deserts, with an emphasis on rare earth elements (REE). Our data confirms that terrestrial weathering in deserts changes (Sr, Ba, REE, Hf, Th, U) concentrations. However, effects...

The present study investigates the frequency and intensity of mineral dust emissions over the deserts of eastern Asia from 1996 to 2001. Mineral dust emissions are simulated using a physical dust emission scheme over a region extending from 35.5°N to 47°N and from 73°E to 125°E. The input parameters required by the dust emission model are (1) surface features data including aerodynamic roughnes...

Tensions between the world of science and the world of law may arise because of their differing viewpoints and philosophies. Disagreements may center around such questions as what constitutes proof, around human behavior, and around the use of the insanity defense in criminal cases. The just deserts model is examined and is criticized as being harsh and possibly unrealistic in today's society.
