All Flashcards
What determines if a species is a generalist or specialist?
Niche breadth, diet flexibility, location requirements, and tolerance range.
Why are generalist species more likely to survive in changing environments?
Their broad niche and adaptability allow them to utilize different resources and habitats.
Why are specialist species more vulnerable to environmental changes?
Their narrow niche and specific requirements make them highly sensitive to disruptions.
Explain the relationship between diet and species classification.
Generalists have flexible diets, while specialists have limited or specific diets.
How does location affect species classification?
Generalists can live in various locations, while specialists require specific habitats.
What is the significance of a species' tolerance range?
It determines how well a species can withstand environmental changes and disturbances.
What is the impact of deforestation on generalist and specialist species?
Deforestation reduces habitat and resources, favoring generalists while harming specialists.
Deforestation effects on specialists?
Habitat loss and reduced food sources lead to population decline.
Environmental change effects on generalists?
Increased competition, but higher survival rates due to adaptability.
Loss of bamboo effects on pandas?
Starvation and population decline due to their specialized diet.
Climate change effects on polar bears?
Melting sea ice reduces hunting grounds, leading to starvation.
Invasive species effects on specialists?
Competition for resources leads to decline in specialist populations.
Habitat fragmentation effects on specialists?
Reduced access to resources and mates, leading to genetic bottlenecks.
Pollution effects on sensitive species?
Decline in populations of species with low tolerance ranges.
Overhunting effects on specialist predators?
Disruption of food webs and decline in prey populations.
Introduction of new diseases effects on specialists?
Rapid population decline due to lack of immunity.
Loss of keystone species effects on the ecosystem?
Cascading effects leading to loss of biodiversity and ecosystem instability.
Define generalist species.
Species with a broad niche, adaptable to a wide range of conditions.
Define specialist species.
Species with a narrow niche, requiring specific conditions to survive.
What is a niche?
The role and position a species has in its environment.
Define adaptability.
The ability of a species to adjust to new conditions.
Define resilience.
The ability of a species or ecosystem to recover from disturbances.
Define tolerance range.
The range of environmental conditions a species can withstand.
What is a broad niche?
A wide range of resources and conditions a species can utilize.
What is a narrow niche?
A limited range of resources and conditions a species can utilize.
Define environmental disturbance.
A temporary change in environmental conditions that causes a pronounced change in an ecosystem.
What is species composition?
The variety and abundance of different species in a given area.
