How does latitude and longitude affect biodiversity?

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).

What is the impact of latitude and altitude on the distribution of biodiversity?

With the change in altitude and latitude there is a change in the sunlight distribution patterns which indirectly affects the viability and germination of the seeds. So plants thriving in areas with low light intensity will survive more in high altitude region and vice versa and hence more widely distributed.

How does latitude affect species richness of a community?

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.

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 increases biodiversity?

As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance.

How does altitude affect biodiversity?

Environmental gradients such as altitude are also known to affect biodiversity and may interact with anthropogenic forces that shape ecosystem function. Higher altitudes are associated with a decline in species richness in many groups of animals, including insects (Lawton, Macgarvin & Heads 1987; Hodkinson 2005).

How does altitude and latitude affect organisms in a biome?

As latitude and altitude increase, biomes and vegetation change. Trees of tropical rainforests usually grow closer to the equator, while mosses and lichen of the tundra grow closer to the poles.

Which factor affects biodiversity the most?

In freshwater ecosystems:

water regime changes, such as those following the construction of large dams; invasive species, which can lead to species extinction; and pollution, such as high levels of nutrients. More…

Does longitude affect species richness?

Does Species richness vary with latitude or longitude? Latitude. Some groups of organisms display the opposite pattern in latitudinal diversity. If we assume dispersal is the same around the world, the rate of speciation and extinction are going to drive species richness.

What are the two factors that affect species diversity?

The factors related to these patterns of small- scale species richness include (1) geographic factors such as scale of observation, available species pool and dispersal patterns, (2) biotic factors such as competition or predation and (3) abiotic environmental factors such as site resource availability, disturbance and …
