Why choose Atlas Worldâs Agaricus blazei. Atlas Worldâs patented strain of Agaricus blazei Murill (H1X1), was developed by expert mycologists. H1X1 is the product of two parent strains, one cultivated in northern California known as SBRFG, and another parent strain cultivated in Japan known as I-101.
Biological Species Concept. The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance.Although appearance is helpful in identifying species, it does not define species.Appearance isnt everything.1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.ppearance isnt everything. 1  Organisms may appear to be alike and be different species. 2  For example, Western meadowlarks (Sturnella neglecta) and Eastern meadowlarks (Sturnella magna) look almost identical to one another, yet do not interbreed with each otherthus, they are separate species according to this definition.
âA biological species is a group of interbreeding or potentially interbreeding organisms that can produce viable offspring.â. Advantages: This is a species concept based on a mechanism. Either individuals can or cannot produce viable offspring, although failure may be down to individuals.The issue of potential interbreeding arises when members of populations are separated but are brought into contact in a lab, or by chance mechanisms.hatâs right, definitions plural. Different areas of biology use different species concepts, depending on the organisms and data available. Each of the major species concepts is explained below, along with the advantages and disadvantages of the species concept and which areas of biology use the definition.
