Theoretical and empirical derivation of cardiovascular allometric relationships in children.

Allometric Convergence in Savanna Trees and Implications for the Use of Plant Scaling Models in Variable Ecosystems

Theoretical models of allometric scaling provide frameworks for understanding and predicting how and why the morphology and function of organisms vary with scale. It remains unclear, however, if the predictions of 'universal' scaling models for vascular plants hold across diverse species in variable environments. Phenomena such as competition and disturbance may drive allometric scaling relatio...

Evaluating scaling models in biology using hierarchical Bayesian approaches

Theoretical models for allometric relationships between organismal form and function are typically tested by comparing a single predicted relationship with empirical data. Several prominent models, however, predict more than one allometric relationship, and comparisons among alternative models have not taken this into account. Here we evaluate several different scaling models of plant morpholog...

Effects of Herbivory on Plant and Soil Characteristics; Allometric Relationships Change among Different Grazing Sites

Improved estimation of intrinsic growth r(max) for long-lived species: integrating matrix models and allometry.

Intrinsic population growth rate (r(max)) is an important parameter for many ecological applications, such as population risk assessment and harvest management. However, r(max) can be a difficult parameter to estimate, particularly for long-lived species, for which appropriate life table data or abundance time series are typically not obtainable. We describe a method for improving estimates of ...

Theoretical Explanation of the Use of Cyberspace and the Evolution of Family Structure in Iran with Emphasis on the Concept of Generation Gap

The family is the vital source of peace and comfort, love and intimacy. But the family can also be a place of conflict, difference, gap and distance in terms of values ​​and patterns of behavior between children and parents. Virtual social networks are a new generation of social networking space that at the end of the first decade of the 21st century have changed the ways of communic...
