Description

Data from a two-part greenhouse study in Glencoe, IL, USA the first of which had 3 interaction treatments (control group, intraspecific interactions with 3 Pascopyrum smithii conspecific plants, and interspecific interactions with 2 Bromus tectorum as heterospecific neighbors in each pot). Data in experiment one are collected on the focal P. smithii plant for root mass, shoot mass, root mass fraction (RMF), plant height, and number of leaves. This experiment showed that interactions between P. smithii and conspecifics resulted in largely canalized traits and size similar to the control group, whereas, and P. smithii with the invasive grass Bromus tectorum resulted in plastic responses for root mass (p = 0.02), shoot mass (p < 0.0001), root mass fraction (p = 0.003) and plant height (p < 0.0001). For experiment two, a subset of individuals transplanted from these two interaction treatments with new, same aged conspecific P. smithii showed that interspecific-induced P. smithii produced more leaves than the intraspecific-induced focal plant (p <0.0001) and that the previous interactions led to differing relationships in which increases in the number of leaves for the interspecific-induced plant was related to increases in non-focal leaf production, whereas increases in the number of leaves for the intraspecific-induced plant was related to decreases in the non-focal plant (R2 = 0.52, p = 0.006). Intraspecific-induced focal plants imposed greater competition on new neighbors than invasive-interspecific interactions.
