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.
How does habitat destruction affect specialist species?
It reduces their specific resources and habitats, leading to population decline.
How does climate change affect specialist species?
Changes in temperature and precipitation can alter their specific habitat requirements, threatening their survival.
How does the introduction of invasive species affect native specialist species?
Invasive species compete for resources and can outcompete specialist species, leading to their decline.
How does pollution affect specialist species?
Pollution can contaminate their specific food sources and habitats, leading to health problems and population decline.
What is the effect of a natural disaster on specialist species?
Specialist species are severely affected by natural disasters because they cannot easily move to new biomes.
