What is the definition of diversification? The Export Diversification Database has three main indicators: the Export Diversification Index, the Extensive Margin, and the Intensive Margin. Each species in the interaction applies selection pressure on the others. Evolution - Evolution - Diversity and extinction: The current diversity of life is the balance between the species that have arisen through time and those that have become extinct. Evolution describes the cumulative changes that occur in the heritable characteristics of a population. diversification, and a new definition of the clade Linda A. Tsuji* and Johannes Mller Museum fr Naturkunde Berlin, 10115 Berlin, Germany. It can result in diversification within a species (microevolution) or diversification between species (macroevolution) Microevolution. (2006) says it’s a collection of businesses under one corporate umbrella. Historical changes in diversity: Many events have left their marks on the diversity of life on Earth, pruning or growing the tree of life, but a few stand out as unusually important: Alternative splicing and evolution: diversification, exon definition and function Hadas Keren, Galit Lev-Maor and Gil Ast Abstract | Over the past decade, it has been shown that alternative splicing (AS) is a major mechanism for the enhancement of transcriptome and proteome diversity, particularly in … The export diversification and quality database was developed by IMF staff under an IMF-DFID research collaboration. The rapid diversification of mammals shown below may constitute an adaptive radiation. With respect to phenotypic evolution, the two processes may be seen as opposite ends of a spectrum; however, there is no straightforward method for the comparative analysis of trait evolution that will identify these contrasting scenarios. Definition: Diversification can be understood as the corporate strategy that a company implements to increase the market share and sales volume by introducing new products in new markets or industry, which is distinct from its core business. 2007). Higher values for the all three indices indicate lower diversification. Paleontologists observe that organisms have continuously changed since the Cambrian Period, more than 500 million years ago, from which abundant animal fossil remains are known. What Does Diversification Mean? Apart from the definitions by scholars like (Turner, 2005; Thompson & Strickland, 2006; Aggarwal & Samwick, 2003), Johnson et al. Definition: Diversification is a growth strategy that capitalizes on market opportunities by allocating investment risk over different asset classes. The concept of diversification is yet to be clearly defined and there is no consensus on the precise definition among researchers. Diversified Carry Basket: A forex trading strategy in which multiple carry trades are conducted simultaneously in order to limit risk. Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. Diversification is an asset allocation plan, which properly allocates assets among different types of investment. Coevolution can lead to specialized relationships, such as between predator and prey. In those models, species are characterized by an evolving trait, and their diversification follows a birth–death process in which speciation and extinction rates may depend on the trait state. The concepts of niche conservatism and adaptive radiation have played central roles in the study of evolution and ecological diversification.
