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.
Why are K-selected species more vulnerable to extinction?
Their low reproductive rate and long generation time make it difficult to recover from population declines.
Why is biodiversity important?
It provides ecosystem services, supports food webs, and offers economic and intrinsic value.
How does habitat fragmentation affect species?
It reduces habitat size, isolates populations, and increases edge effects, leading to decreased biodiversity.
What is the role of zoos in conservation?
Zoos can help rebuild populations of critically endangered species through breeding programs and raise public awareness.
How does trade impact endangered species?
Legal and illegal trade can threaten species through overexploitation for fur, medicinal parts, and exotic pets.
What is the significance of the IUCN Red List?
It categorizes species based on their risk of extinction, providing a global standard for assessing conservation status.
Why are specialist species vulnerable?
They have very specific niche requirements and cannot adapt to changing environmental conditions or habitat loss.
How does overharvesting lead to endangerment?
Removing individuals faster than they can reproduce causes population decline, potentially leading to endangerment or extinction.
What are the benefits of protecting critical habitats?
It ensures species have the resources and space needed to survive and reproduce, aiding in population recovery.
How does education aid conservation efforts?
It raises public awareness and encourages support for conservation actions, promoting responsible behavior and policy changes.
How can education help protect endangered species?
Raises public awareness, encourages support for conservation efforts, and promotes responsible behavior.
How do breeding programs contribute to conservation?
Help rebuild populations of critically endangered species, increasing their numbers and genetic diversity.
How can habitat restoration support endangered species?
Provides suitable environments for species to thrive, increasing their chances of survival and reproduction.
How do protected areas contribute to biodiversity conservation?
Provide safe havens for species, preserving habitats and reducing human impacts.
How can sustainable agriculture practices benefit wildlife?
Reduces habitat destruction, minimizes pesticide use, and promotes biodiversity on agricultural lands.
How does ecotourism support conservation efforts?
Generates revenue for local communities, incentivizes habitat protection, and raises awareness among tourists.
How can reducing meat consumption help conserve biodiversity?
Decreases demand for land used for livestock grazing and feed production, reducing habitat loss and deforestation.
How do wildlife corridors promote genetic diversity?
Connect fragmented habitats, allowing for gene flow between isolated populations and reducing the risk of inbreeding.
How can citizen science initiatives contribute to conservation?
Engage the public in data collection and monitoring, providing valuable information for research and management.
How does reducing plastic consumption protect marine species?
Decreases plastic pollution in oceans, reducing the risk of entanglement, ingestion, and habitat contamination for marine life.
