What is the effect of ecosystem disruptions on species?
Ecosystem disruptions can lead to selective pressures, favoring some species over others, and potentially leading to extinction for those that cannot adapt.
What is the effect of invasive species on an ecosystem?
Invasive species can dominate and disrupt established ecosystems, leading to declines in native populations.
What is the effect of habitat destruction on biodiversity?
Habitat destruction reduces biodiversity by eliminating habitats for many species.
What is the effect of climate change on ecosystems?
Climate change alters environmental conditions, potentially leading to shifts in species ranges, altered food webs, and increased frequency of extreme weather events.
What is the effect of mutations on a population?
Mutations can introduce new alleles, potentially leading to fitness benefits or disadvantages.
What is an adaptation?
A heritable genetic variation that increases an organism's fitness.
Define natural selection.
The process where heritable variations lead to differential reproductive success.
What are invasive species?
Non-native species that disrupt ecosystems, often lacking natural predators.
What are anthropogenic impacts?
Human-caused changes to the environment, such as habitat destruction and pollution.
Define intraspecific competition.
Competition for resources within the same species.
Define interspecific competition.
Competition for resources between different species.
What are the four principles of natural selection (VIND)?
Variation, Inheritance, Natural Selection (Differential Survival), Differential Reproduction.
