Trends in pairs figure skating have shown that increasingly difficult jumps have become an essential aspect of high-level performance, especially in the latter part of a competitive program. We compared a repeated jump power index in a 60 s repeated jump test to determine the relationship of repeated jump test to competitive rank and to measure 2D hip, knee, and ankle angles and angular velocit...

1. Competition effects on growth of individual trees were examined for 4 years in aggrading, mixed-clone stands of trembling aspen ( Populus tremuloides Michx.) at the Aspen-FACE free-air CO 2 and O 3 enrichment facility in northern Wisconsin, USA. During each growing season stands received one of four combinations of atmospheric [CO 2 ] (ambient vs ∼ 56 Pa) and [O 3 ] (ambient vs ∼ 1·5 × ambie...

The ecological principle of competitive exclusion states that species competing for identical resources cannot coexist, but this principle is paradoxical because ecologically similar competitors are regularly observed. Coexistence is possible under some conditions if a fluctuating environment changes the competitive dominance of species. This change in competitive dominance implies the existenc...
