This paper concerns itself with the study of sand beaches of the Boujagh National Park with an area of 3477 ha. The purposes of this study include the determination of the plant species diversity and plant groups. In ad-dition, the determination of the impact of environmental and specific variables on the presence or absence of certain species and their communities is another aim that the study...

Theatrical metaphors abound within the literature on nurse education and perhaps it is no accident that they do so. However much of the nursing literature implies that clinical learning involves the student in developing performance skills, and infers that this type of learning is inferior and superficial.

To evaluate the role of deer in regulating the abundance of the deer tick (Ixodes dammini) we attempted to treat with acaricide, but eventually removed, about 70 percent of deer from Great Island, Cape Cod, Massachusetts. Deer were captured in box traps, a corral, an entanglement net, and with rifle-fired tranquilizer. Failure of these attempts, combined with ineffective acaricides, led us to d...
Species distribution models (SDMs) are a general suite of models that relate the frequency of species occurrences (presence only or presence/absence) to sets of environmental variables. These relationships can then be used to generate predictions of the geographic areas where the species are expected to occur, making SDMs powerful and widely used tools in conservation biology, biogeography and ...
The aim of this study was to assess the influence of trout farm effluents on water quality parameters in the Dohezar Stream. In this study two trout farms and 7 stations were selected and physiochemical of water, including air and water temperatures, dissolved oxygen concentration (DO), pH, electrical conductivity (EC), water flow and biochemical oxygen demand (BOD) were measured every 30 days ...
