Soil Sci. 82: 1–8. Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared...

Livestock grazing is an important element in ecosystem regulation since it may affect essential functions, such as nutrient acquisition, organic matter decomposition, or litter accumulation the soil. Overgrazing can threaten conservation of ecosystems through excessive defoliation plants trampling. On contrary, moderate have benefits on dynamics by favoring cycling soil microbial activity. The ...

Taphonomic modifications on animal bones have the potential to provide a wealth of information on the depositional histories of faunal assemblages. However, certain modifications have received little attention and their interpretation remains complex due to their varied or uncertain aetiology. This has hindered progress in approaches to taphonomic research and it remains relatively rare that a ...

The effect of habitat management is commonly evaluated by measuring population growth, which does not distinguish changes in reproductive success from changes in survival or the effects of immigration or emigration. Management has rarely been evaluated considering complete life cycle of the target organisms, including also possible negative impacts from management. We evaluated the effectivenes...

T 's a small world after all. At least, that's what the millions of tourists who take to the skies, roads, and paths each year to discover it are finding. Advances in technology and transportation and the emergence of a global economy are providing greater access for unprecedented numbers of travelers to explore the once-remote world around them. Directly and indirectly, however, tourism may of...
