A distance measure between plant architecture

چکیده
In many biological fields (e.g. horticulture, forestry, botany), a need exists to quantify different types of variability within a set of plants. In this paper, we propose a method to compare plant individuals based on a detailed comparison of their architectures. The core of the method relies on an adaptation of an algorithm for comparing rooted tree graphs, recently proposed by Zhang in theoretical computer science. Using this algorithm a distance between two plants is defined as the cost of transforming one into the other (using basic “edit operations”). We illustrate this method in three application fields and then compare it with other methods for quantifying plant similarity. Key Word: topological structure of plants / plant comparison / analytical method Définition d'une distance entre architectures de plantes Résumé: Dans de nombreux domaines de la biologie (arboriculture, sylviculture, botanique), il est nécessaire d’étudier différents types de variabilité au sein d’une population de plantes. Nous proposons, dans ce papier, une méthode de comparaison des plantes basé sur une comparaison détaillée de leur architecture. Cette méthode est une adaptation d’un algorithme de comparaison d’arborescences, proposé récemment par Zhang en informatique théorique. Cet algorithme nous permet de définir une distance entre deux plantes comme le coût de la transformation de l’un en l’autre (à l’aide d’opérations élémentaires d’édition). Cette méthode est illustrée dans trois domaines d’application et elle est comparée à d’autres méthodes de quantification de la ressemblance entre plantes. Mot Clé: structure topologique des plantes / comparaison des plantes/ méthode analytique

متن کاملEvaluation of Distance and Quadratic Indices for Determination of Plant Species Distribution Pattern in Khoosef Rangelands, Birjand, Iran
One of the major issues examined in the quantitative ecology is the spatial distribution pattern of plant species. Knowledge of the spatial distribution patterns is essential to measure the level of uniformity in the surrounding environment, plant reproduction, and distribution of the seedlings, plant behavioral patterns, coexistence, allelopathic relations, and competition. Therefore, the aim ...
متن کاملA study on dimensions of Fractal geometry in Iranian architecture
The subject of geometry and proportions has been regarded as an issue which has a close relationship with architecture. Since the entire universe, living beings and the human geometry can be seen clearly, that’s why our unconscious essence has accustomed to these proportions whereby reflection of this mentality can be seen in the architect’s hands and thought in the architecture. It can witness...
متن کاملThe Geometry of Karbandi in Persian Architecture; Response to the Challenges of Conventional and Stellar Karbandi
Karbandi is one of the original and ancient arched elements in Persian architecture which is formed based on a network with harmonic geometry and in addition to architectural function, it also has structural behavior. However, there are ambiguities about the geometry of this architectural element that should be addressed with targeted research. One of these ambiguities is to determine how the g...
