Fertilization effects on interactions between above-and belowground competition in an old field
Download1999-01-01
Recent theoretical and experimental studies have addressed whether the relative importance of aboveground and belowground competition changes along gradients of biomass productivity. Results have been contradictory, with some researchers finding a decrease in the importance of belowground...

Limited effects of soil nutrient heterogeneity on populations of Abutilon theophrasti (Malvaceae)
Download1996-01-01
An experiment was conducted to determine if spatial nutrient heterogeneity affects mean plant size or size hierarchies in experimental populations of the weedy annual Abutilon theophrasti Medic. (Malvaceae). Heterogeneity was imposed by alternating 8 X 8 X 10 cm blocks of low and high nutrient...

Population-level Responses to Nutrient Heterogeneity and Density by Abutilon Theophrasti (Malvaceae): An Experimental Neigborhood Approach
Download1998-01-01
An experimental approach was used to examine the effects of spatial nutrient heterogeneity and planting density on the sizes of plants within populations of Abutilon theophrasti. Planting locations were generated using random numbers and replicated among populations growing on two different...
