All Flashcards
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.
Significance of niche breadth?
Determines a species' vulnerability to environmental change.
Why are generalists more resilient?
They can utilize a wider variety of resources and adapt to new conditions.
Why are specialists more vulnerable?
They depend on specific resources and cannot easily adapt to change.
How does diet affect species survival?
Flexible diets increase survival chances in changing environments.
How does location affect species survival?
Sensitivity to location changes increases vulnerability for specialists.
How does tolerance affect species survival?
High tolerance to environmental changes increases resilience.
How does deforestation impact species?
Reduces habitat and resources, affecting specialists more severely.
What is the role of generalists in ecosystems?
Help maintain stability by utilizing various resources.
What is the role of specialists in ecosystems?
Contribute to biodiversity by occupying specific niches.
How does climate change affect species?
Shifts in climate can severely impact specialist species.
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.
