The hot spots of biodiversity conservation are characterized by:
1. High endemicity and high threat of extinction
2. Low endemicity and high threat of extinction

Which of the following has maximum global biodiversity?
1. Angiosperms
2. Algae
3. Lichens
4. Mosses
What is applicable to both Lates niloticus and Lantana camara ?
1. They are on the verge of extinction due to over-exploitation by humans.
2. They are alien species that became invasive in certain environments causing threat to indigenous biodiversity.
3. They are mutualists and likely to undergo co-extinction in recent future.
4. They are keystone species and are vital to the stability of tropical ecosystems.
The most effective means of conservation of biodiversity is:
1. Remove predators
2. Preserve habitats
3. Vaccinate against disease
4. Census the species during breeding season
