"Genetic diversity can have important ecological consequences at the population, community, and ecosystem levels, and in some cases, the effects are comparable in magnitude to the effects of species diversity (Article Ecological consequences of genetic diversity

"The challenge comes in measuring such a broad concept in useful ways. Although biodiversity can never be fully captured by a single number, studying particular facets has led to rapid, exciting, and sometimes alarming discoveries. Phylogenetic and temporal analyses are shedding light on the ecological and evolutionary processes that have shaped current biodiversity (Article Getting the Measure of Biodiversity

"The variation in the genetic make-up of organisms. This usually refers to the genetic variation within a population or a species, but it can also refer to the variety of species, genera, families, or other taxonomic groupings. These different taxonomic levels reflect a gradient from the most genetically similar to the least genetically similar groupings of organisms (Article Biodiversity and its relationship to ecosystem health and integrity

Dear Pablo Octavio Aguilar thank you for your contribution to the discussion

Biodiversity is the variety of plants and animals inhabiting in an ecosystem. It includes species diversity, genetic diversity and ecosystem diversity. Genetic diversity is defined as genetic variability present within species. Genetic diversity can be measured directly by looking at genes and chromosomes or indirectly by looking at physical features of the organisms and assuming they have a genetic basis. Using the genetic code is arguably the strongest method of measuring biodiversity as it is looking at the building blocks of life. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth. Genetic Diversity is the diversity of genetic characteristics within a species. All the biological data and variation that makes life on our planet work is encoded in DNA. This is known as genetic diversity. It strengthens the ability of species and populations to resist diseases, pests, changes in climate and other stresses. Genetic diversity is important because it gives species a better chance of survival. However, genetic diversity can be lost when populations get smaller and isolated, which decreases a species' ability to adapt and survive. Genetic diversity is the biological variation that occurs within species. It makes it possible for species to adapt when the environment changes. Genetic diversity is particularly important under rapid environmental change. Genetic diversity can be measured directly by looking at genes and chromosomes or indirectly by looking at physical features of the organisms and assuming they have a genetic basis. Using the genetic code is arguably the strongest method of measuring biodiversity as it is looking at the building blocks of life.
