How does habitat fragmentation affect a population quizlet?
Reduced population numbers which leads to reduced biodiversity. … They can alter biodiversity. Invasive species tend to like community edges since they are usually disturbed areas.
How does habitat fragmentation affect biodiversity quizlet?
How does habitat fragmentation affect biodiversity? … Lowers biodiversity as species have to compete for resources and some will become extinct.
Could the West Indian manatee be considered a keystone species?
Actions taken to protect a certain species may result in protection for other species, or even whole habitats or ecosystem. Could the West Indian manatee be considered a keystone species? … Yes, if it plays an integral role in maintaining the marine ecosystem it lives in, such as controlling the growth of eelgrass.
How does forest fragmentation affect animals?
The effects of fragmentation are well documented in all forested regions of the planet. … When a forest becomes isolated, the movement of plants and animals is inhibited. This restricts breeding and gene flow and results in long-term population decline.
Why is habitat fragmentation detrimental to species quizlet?
Habitat fragmentation can be detrimental to species because: populations of the same species may be separated and would no longer be able to mate. An ecosystem with high species richness but low evenness would have: many different species, with one population being overrepresented in the ecosystem.
How does habitat fragmentation affect genetic diversity within a species?
Habitat fragmentation affects biodiversity by increasing isolation between populations and decreasing effective population size, which alters inbreeding and genetic drift within populations, as well as gene-flow frequency between populations3,4,5. This mechanism can be explained by island biogeography theory6,7.
What is habitat fragmentation and how does it occur?
Fragmentation happens when parts of a habitat are destroyed, leaving behind smaller unconnected areas. This can occur naturally, as a result of fire or volcanic eruptions, but is normally due to human activity. A simple example is the construction of a road through a woodland.
How do species avoid competition?
Competitive exclusion may be avoided if one or both of the competing species evolves to use a different resource, occupy a different area of the habitat, or feed during a different time of day. … This is called resource partitioning, and it helps the species coexist because there is less direct competition between them.
