The body-size dependence of mutual interference

The body-size dependence of mutual interference.

The parameters that drive population dynamics typically show a relationship with body size. By contrast, there is no theoretical or empirical support for a body-size dependence of mutual interference, which links foraging rates to consumer density. Here, I develop a model to predict that interference may be positively or negatively related to body size depending on how resource body size scales...

The body size dependence of trophic cascades.

Trophic cascades are indirect positive effects of predators on resources via control of intermediate consumers. Larger-bodied predators appear to induce stronger trophic cascades (a greater rebound of resource density toward carrying capacity), but how this happens is unknown because we lack a clear depiction of how the strength of trophic cascades is determined. Using consumer resource models,...

Mutual Dependence Demands Mutual Sharing

Measuring Dependence via Mutual Information

Considerable research has been done on measuring dependence between random variables. The correlation coefficient [10] is the most widely studied linear measure of dependence. However, the limitation of linearity limits its application. The informational coefficient of correlation [17] is defined in terms of mutual information. It also has some deficiencies, such as it is only normalized to con...

Size Dependence of the Elastic Properties of Pd Nanowire: Molecular Dynamics Simulation

The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...
