| Question | Answer |
|---|---|
| a common social challenge to rewinding large carnivores is | concern over livestock predation and human safety leading to apposition from local communities |
| illegal wildlife trade most directly contributes to biodiversity loss by | driving declines and extinctions of targeted wild populations |
| Which is a common driver of tropical deforestation | Large-scale conversion for agriculture |
| species recovery plans most often aim to | reduce threats, restore populations, and improve habitat to prevent extinction |
| which is commonly cited as a keystone species in many ecosystems | top predators or ecosystem engineers |
| which best defines a biodiversity hotspot | a region with high levels of native species and significant habitat loss |
| how does agricultural expansion commonly reduce biodiversity | by converting natural ecosystems to monocultures and fragmenting habitat |
| a key factor for successful species reintroduction is | ensuring suitable habitat, low threats, genetic diversity, and long-term monitoring |
| which action is ex situ conservation? | captive breeding of endangered animals in a zoo |
| climate change reduces biodiversity primarily by | shifting climate zones faster than many species can adapt or migrate |
| why are biodiversity hotspots often prioritized for conservation | they contain many endemic species found nowhere else |
| which is an example of in situ conservation | protected wildlife reserve where species live naturally |
| which human activity is currently the largest driver of global biodiversity loss | habitat destruction |
| a key limitation of ex situ conservation is | it can be costly and may not preserve natural behaviors or ecological roles |
| which statement about introduced species is generally true | they sometimes become invasive and harm native species and ecosystems |
| controlling invasive marine species is particularly difficult because | ocean connectivity and complex life cycles make eradication and containment challenging |
| which distinguishes a mass extinction from background extinction | mass extinctions involve many species lost in a relatively short time |
| a well-managed ecotourism program can support conservation by | generating revenue for protected area management and giving local |
| how can new diseases contribute to biodiversity loss | by reducing population sized and causing local extinctions |
| what is a major ecological consequence of habitat fragmentation | greater genetic isolation of populations |
