Researchers found that while the tropics harbor more species, the number of subspecies increases in the harsher environments typical of higher latitudes. … Scientists have known for more than a century that species diversity increases towards the equator.
How does latitude affect biodiversity?
Species density is higher in the tropics (low latitude) than in temperate regions (high latitude) resulting in a latitudinal biodiversity gradient (LBG).
Does biodiversity increase as latitude increases?
Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as the latitudinal diversity gradient (LDG).
What generally happens to biodiversity as the latitude increases group of answer choices?
Species richness in both terrestrial and marine environments generally declines with latitude. … As the structural diversity of plant communities increases, the species richness of animals also increases. True. The species richness of terrestrial plants and animals generally increases with elevation.
How does biodiversity generally changed with increasing distance to the equator?
Generally speaking, diversity increases as you move away from the polar regions and towards the equator. A possible explanation for this is that greater primary productivity at the equator has lead to greater biodiversity. Having more energy available in this area means more consumers can be supported.
How are latitude and longitude similar and different?
Latitudes are measured in degrees. Longitudes: The vertical lines running north-south, join the two poles.
What is the difference between Latitude and Longitude?
|It is known as parallels||It is known as meridians|
|The length of the lines are different||The length of the lines are the same|
What is latitude gradient of bio diversity?
Latitudinal gradients of biodiversity are biogeographic patterns that define the way in which components of taxonomic, phylogenetic, functional, genetic, or phenetic dimensions change with latitudinal position on the surface of the earth.
Why does biodiversity increase towards the tropics?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
What is the relationship between diversity and latitude quizlet?
What is the relationship between diversity and latitude? As latitude increases, moving away from the equator at the center of the Earth toward either the North Pole or the South Pole, biodiversity decreases.
Which latitude will have more biodiversity?
For more than three centuries Western science has known that biodiversity is greatest in the tropics. European explorers and traders returned from Africa, Asia and the Americas with thousands of specimens of previously unknown kinds of animals and plants.
Is biodiversity has no effect on change in latitude?
HEY THE ANSWER IS THAT. BIO DIVERSITY IS DECREASE TOWARDS THE EQUATOR.
Why does biodiversity increase from the poles to the equator?
Explanation: This idea is also referred to as the latitudinal diversity gradient, meaning that as you move from the equator towards the poles, diversity lessens. … Some also believe greater primary productivity at the equator has lead to greater biodiversity.
How does latitude affect species richness?
Global scale analyses have recently revealed that the latitudinal gradient in marine species richness is bimodal, peaking at low-mid latitudes but with a dip at the equator; and that marine species richness decreases with depth in many taxa.
Where does biodiversity generally increase from?
Generally, there is an increase in biodiversity from the poles to the tropics. Thus localities at lower latitudes have more species than localities at higher latitudes. This is often referred to as the latitudinal gradient in species diversity.
Why does biodiversity tend to be higher in areas closest to the equator or tropical areas?
A new study led by Oxford Earth Sciences’ Associate Professor Erin Saupe suggests that higher species diversity in equatorial regions may be caused by higher rates of speciation (the formation of new and distinct species in the course of evolution), driven by changes in precipitation across space and through time.
Why does biodiversity tend to be higher in areas closest to the equator or tropical areas quizlet?
Why are areas near the equator have more species richness? Greater amounts of solar energy, heat, and humidity at tropical latitudes lead to more plant growth, making areas nearer the equator more productive and able to support larger numbers of animals.
