One major geographic pattern in biodiversity is the latitudinal gradient in species richness. As one travels further away from the equator, for most taxa, the number of species declines.
How does area affect biodiversity?
Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species. In addition, many species require a large range for adequate prey or seed forage.
What are the factors affecting biodiversity?
Major threats to biodiversity are:
- Habitat destruction/Deforestation.
- Introduced and invasive species.
- Genetic pollution.
- Over exploitation.
- Climate change.
- Human over-population.
What are the 5 main factors affecting biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
Which affects biodiversity the most?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
How does habitat change affect biodiversity?
Habitat loss has significant, consistently negative effects on biodiversity. Habitat loss negatively influences biodiversity directly through its impact on species abundance, genetic diversity, species richness, species distribution, and also indirectly.
Why is biodiversity important in urban areas?
Urban areas, with their highly transformed landscapes and rapid human-caused changes to local ecosystems are accepted as a major driver of biodiversity change. … The introduction of invasive species to ecosystems (biotic exchange).
What factors affect biodiversity Why do wetlands have a high level of biodiversity?
Wetlands have a high level of biodiversity because of the amount of resources available. The high levels of accessible water, nutrient levels, and primary productivity allow for a large number and variety of organisms at the base of the food web.
Why does climate change affect biodiversity?
As the planet warms quickly, mostly due to human activity, climate patterns in regions around the world will fluctuate. Ecosystems and biodiversity will be forced to fluctuate along with the regional climate, and that could harm many species.
What are the causes of biodiversity and destruction?
Reason for Loss of Biodiversity

- Genetic Pollution.
How does climate change affect biodiversity Brainly?
Explanation: Rising temperatures are likely to result in widespread ecological change. Many animal and plant species are likely to become extinct as ecosystems adjust to climate change. While adaptable species will survive, and other migrate, the end result will be lost biodiversity.
