Deforestation and agriculture
Other factors affecting species diversity
These building blocks have different properties and serve to function as structural and functional components such as cell walls, enzymes, genetic material, metabolites, energy stores, etc. Just as 4 DNA variables (adenine, guanine, cytosine and thymine) can serve to encode the entire genetic diversity of life, all these basic classes of chemicals together can create so many different configurations of life that it generates diversity of organisms at the individual and species level.
Species diversity is the diversity of species in a community. Put simply, how many different species are there in a community? 5 or 5,000? Which has the higher diversity? Not rocket science i hope.
^That’s some rocket science, I don’t really know what it is, but I don’t wish to find out, and neither do you. Just a little motivator to not complain about biology.
Species richness is defined by the number of different species in a habitat. However, in order to have biodiversity, the relative abundance of each species is also key. The more species, the higher the diversity. What if there are two separate communities like this:
- Community #1 has 150 individuals per each of 20 different species (3000 individuals in total)
- Community #2 has 10 individuals per each of 19 species, and 2990 individuals of the last species (3000 individuals in total)
It doesn’t take a complex formula to figure out that community #1 is far more diverse compared to community #2, despite them having the same number of species and…
