Study Notes
Biodiversity Loss and Conservation in Australia
- Biodiversity loss since European colonization is severe.
- There are 4 reasons for hopeful conservation:
- Australia is a single nation, making responses easier.
- The country is politically stable and wealthy, which allows for consistent conservation strategies.
- The low population density caps environmental pressure.
- Indigenous peoples' cultural care for Country continues to manage large areas of the continent, and many Australians want no further extinctions.
Biggest Threat to Australian Biodiversity
- Invasive species are the biggest threat.
- Island biogeography theory dictates that the number of species on an island is determined by a balance between immigration (new species arrival) and extinction (existing species loss).
- Invasive species rapidly colonize and increase extinction rates of existing species.
Roles of Mammals in Australian Ecosystems
- Many extinct or declining mammal species played crucial roles in the ecosystem, like soil turnover, seed dispersal, germination, and as keystone predators.
Drivers of Plant and Frog Loss
- Habitat clearance and degradation are the main drivers of plant loss.
- Chytrid fungus is the main driver of frog loss. It emerged in the 1970s.
