Identifying components of biodiversity education using a meta-analysis approach

Abstract

Introduction: This qualitative and applied research was conducted with the aim of designing a hierarchical model of biodiversity. Materials & Methods: Its investigation method is descriptive-analytical of meta-analysis type. The statistical population included 27 researches conducted inside and outside the country in the form of articles, theses and research projects. Results: Based on this, the comprehensive model with three dimensions of intraspecies diversity, extra species diversity and ecosystem diversity and in 23 components of genes and genetic structure, individuals, genetic information, genetic processes, diversity of traits and subspecies in the dimension of diversity within species, species, populations, extinction, organisms, evolutionary processes, population structure, the process of interspecies interactions, ecosystems and genus in the dimension of interspecies diversity and ecosystems, habitats, biological communities, ecosystem Terrestrial and marine species, landscapes, biomes, ecological processes, and ecological niches were formed in the dimension of ecosystem diversity. Reliability was calculated through the Kappa coefficient with a value of 0.96, which is at the level of excellent agreement. Conclusion: The results showed that this comprehensive model refers to all the dimensions that have been discussed in various researches and provides a comprehensive model of the integration of existing researches, research and planning in the field of biodiversity, especially for related training. Therefore, it can be claimed that the current research has achieved the goal of developing biodiversity concepts.
