Diversity can be both permanent and transitory. It depends on the context and factors influencing the diversity. In certain cases, diversity can be a constant state due to external factors. However, in other situations, diversity may fluctuate over time based on changes within a system or society.
Fragmentation can lead to a decrease in genetic diversity within populations and increase isolation between populations which can then decrease overall species diversity in an area. This can result in reduced resilience to environmental changes and increase the risk of local extinctions.
Ecosystem diversity, species diversity, and genetic diversity together form the foundation of biodiversity, which is essential for the health and resilience of the planet. Ecosystem diversity refers to the variety of habitats and ecological processes, species diversity encompasses the range of different organisms within those ecosystems, and genetic diversity involves the variation of genes within species. Together, these components contribute to ecosystem stability, adaptability to changes, and the overall functionality of environmental systems, supporting life and human well-being.
Changes in environmental conditions can alter species distributions, leading to shifts in community composition and diversity. Extreme conditions like droughts or heatwaves can reduce biodiversity by causing declines in certain species that are sensitive to these changes. On the other hand, some species may benefit from altered conditions, potentially increasing diversity in an ecosystem.
Genetic diversity refers to the variation of genes within a species, while ecosystem diversity encompasses the variety of ecosystems within a given area. Higher genetic diversity within species can enhance resilience to environmental changes, diseases, and stresses, thereby supporting the stability and functionality of ecosystems. Conversely, diverse ecosystems provide various habitats and resources that can foster greater genetic diversity among species. Together, they contribute to overall biodiversity, which is essential for ecosystem health and adaptability.
There is much diversity in life because of evolutionary changes to the DNA blueprint.

Mutagenesis
Diversity can be both permanent and transitory. It depends on the context and factors influencing the diversity. In certain cases, diversity can be a constant state due to external factors. However, in other situations, diversity may fluctuate over time based on changes within a system or society.
Mutations can lead to changes in an organism's traits, which can be beneficial, harmful, or have no effect. These changes are a natural part of evolution and can drive diversity in populations.
The rare changes in DNA are called mutation ... BUT genetic diversity results from the shuffling of paired genes in normal sexual reproduction. Sex was "invented" to foil parasites, even before two different sexes were developed.
Fragmentation can lead to a decrease in genetic diversity within populations and increase isolation between populations which can then decrease overall species diversity in an area. This can result in reduced resilience to environmental changes and increase the risk of local extinctions.

Low genetic diversity can make a species more vulnerable to diseases, environmental changes, and reduced ability to adapt to new conditions. Inbreeding and genetic disorders are also more likely in populations with low genetic diversity.
