Robustness in Biological Systems - A Provisional Taxonomy
نویسنده
چکیده
Biology is a domain of tension: on the one hand biology is concerned with transformation and the generation of diversity; on the other hand, biology is concerned with the persistence of improbable structural regularitites. Robustness, as a research program, aims to uncover those evolved mechanisms promoting the persistence of regularities. Here I organize mechanisms of robustness into a phenomenological taxonomy, grouping biological mechanisms into principles of robust organization. These include: Redundancy, Purging, Feedback, Modularity, Spatial Compartmentalization, Distributed Processing and the Extended Phenotype. I review studies in which mechanisms representative of each principle are described.

Towards an Australian Bioregionalisation Atlas: A provisional area taxonomy of Australia's biogeographical regions.
The large number, definition, varied application and validity of named Australian biogeographical regions reflect their ad hoc development via disparate methods or case study idiosyncracies. They do not represent a coherent system. In order to resolve these uncertainties an Australian Bioregionalisation Atlas is proposed as a provisional hierarchical classification, accounting for all known nam...
متن کاملA numerical treatment of a reaction-diffusion model of spatial pattern in the embryo
In this work the mathematical model of a spatial pattern in chemical and biological systems is investigated numerically. The proposed model considered as a nonlinear reaction-diffusion equation. A computational approach based on finite difference and RBF-collocation methods is conducted to solve the equation with respect to the appropriate initial and boundary conditions. The ability and robust...
متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...
متن کاملA Review of Fish Taxonomy Conventions and Species Identification Techniques
Taxonomists, ecologists, geneticists or researchers from other biological fields who wish to adopt fish as a constituent of their studies often become discouraged when they find that ichthyology is a complex subject. In fish-based studies, the failure to recognize fishes as distinct biological units can lead to wrong diagnosis. Hence, this review paper attempts to clarify and discuss the latest...
متن کاملTransformation from manufacturing process taxonomy to repair process taxonomy: a phenetic approach
The need of taxonomy is vital for knowledge sharing. This need has been portrayed by through-life engineering services/systems. This paper addresses this issue by repair process taxonomy development. Framework for repair process taxonomy was developed followed by its implementation. The importance of repair process taxonomy has been highlighted.
