All Flashcards
What are the effects of habitat loss on species?
Reduced population size, increased extinction risk, and loss of biodiversity.
What is the effect of overharvesting fish populations?
Decline in fish stocks, disruption of marine ecosystems, and economic losses for fisheries.
How does illegal wildlife trade impact species?
Drives population declines, disrupts ecosystems, and threatens biodiversity.
What is the impact of deforestation on orangutans?
Habitat loss, reduced food availability, and increased vulnerability to hunting.
How does climate change affect endangered species?
Alters habitats, disrupts migration patterns, and increases the risk of extinction.
What are the consequences of poaching?
Rapid population declines, potential extinction, and disruption of ecosystems.
What is the effect of habitat fragmentation?
Reduced gene flow, increased vulnerability to edge effects, and higher extinction rates.
How does pollution affect aquatic species?
Contaminates food sources, disrupts reproduction, and causes disease, leading to population declines.
What are the impacts of invasive species?
Competition with native species, habitat alteration, and disease transmission, leading to native species decline.
What is the effect of human population growth on endangered species?
Increased habitat destruction, resource depletion, and pollution, leading to greater extinction risks.
Define 'Endangered Species'.
A species at risk of extinction because of a significant decline in its population or habitat.
Define 'Threatened Species'.
A species likely to become endangered in the foreseeable future.
What is 'Overharvesting'?
Removing individuals from a population faster than the population can reproduce.
Define 'Specialist Species'.
A species with a very specific niche, vulnerable to environmental changes.
Define 'Generalist Species'.
A species that can adapt to various conditions and has a broad niche.
What is 'Critical Habitat'?
Specific geographic areas that are essential for the conservation of a listed species.
Define 'R-selected species'.
Species with high reproductive rates, many offspring, and low survival rates.
Define 'K-selected species'.
Species with low reproductive rates, few offspring, and high survival rates.
Define 'Poaching'.
Illegal hunting or capturing of wild animals, often for trade.
What does 'Extinct in the Wild' mean?
A species that only survives in captivity or other human-controlled environments.
How can habitat restoration help endangered species?
By providing suitable environments for species to thrive and recover.
How do breeding programs contribute to conservation?
They increase population sizes of critically endangered species and preserve genetic diversity.
How can protected areas aid endangered species?
By providing safe havens from habitat destruction, hunting, and other threats.
How does sustainable harvesting protect species?
It ensures resources are used at a rate that allows for natural replenishment, preventing overexploitation.
How can reducing consumption help endangered species?
It decreases demand for products that contribute to habitat destruction and overexploitation.
How does supporting conservation organizations help?
Provides funding for research, monitoring, and conservation actions.
How can ecotourism benefit endangered species?
Provides economic incentives for conservation and raises awareness among tourists.
How do wildlife corridors protect species?
Connect fragmented habitats, allowing for gene flow and migration.
How can reducing pesticide use protect endangered species?
Prevents unintended harm to non-target species and reduces habitat contamination.
How does community involvement aid conservation?
Ensures local support for conservation efforts and promotes sustainable practices.
