Is the productivity of vegetation plots higher or lower when there are more species? Variable predictions from interaction of the 'sampling effect' and 'competitive dominance effect' on the habitat templet

Article Abstract:

The relation of the productivity of plots within a plant community to the variation in the number of species per plot and the habitat carrying capacity is examined. The decreasing habitat carrying capacity reduces the intensity of the sampling and competitive dominance effects on the productivity/ species richness relationship.

Mycorrhizal species identity affects plant community structure and invasion: a microcosm study

Article Abstract:

Arbuscular mycorrhizal fungi (AMF) are symbiotic fungi that take up resources from the soil and supply them to host plants in exchange of photosynthate. It is found that AMF can affect competition between two plant species, and have the potential to affect the richness, diversity and productivity of the plant species.

The effects of artificial and natural barriers on the movement of small mammals in Banff National Park, Canada

Article Abstract:

The effects of manmade barriers relative to natural barriers and continuous habitat are compared by translocating three species of murid rodents. Results reveal that murid responses to road barriers were only moderately different from responses to the natural barrier of a forest edge in translocation experiments.
