Answer:
The Red Data Books published by the International Union for Conservation of Nature and Natural Resources (IUCN) contain lists of endemic plant and animal species present in the biodiversity hotspots and threatened plant and animal species. Therefore, the correct answer is option 'B' - 2 only.
Explanation:
The Red Data Books are comprehensive databases that provide information on the conservation status of various species. They are published by the International Union for Conservation of Nature and Natural Resources (IUCN) and are considered as a key reference for assessing the conservation status of plant and animal species worldwide.
The Red Data Books contain the following lists:
1. Endemic plant and animal species present in the biodiversity hotspots: Biodiversity hotspots are regions that are rich in biodiversity but also face significant threats due to habitat loss, climate change, and other factors. These hotspots are home to a large number of endemic species, which are found nowhere else in the world. The Red Data Books list these endemic species to highlight their conservation significance and the need for their protection.
2. Threatened plant and animal species: The Red Data Books also list species that are considered threatened or at risk of extinction. These species are categorized into different categories such as critically endangered, endangered, vulnerable, etc., based on their population size, geographical range, and other factors. By listing these species, the Red Data Books draw attention to their conservation needs and help prioritize conservation efforts.
In addition to these two lists, the Red Data Books do not contain information about protected sites for conservation of nature and natural resources in various countries. Therefore, option 'B' - 2 only is the correct answer.
It is important to note that the Red Data Books are regularly updated to reflect the latest scientific knowledge and changes in the conservation status of species. They play a crucial role in informing conservation policies, management plans, and conservation actions at various levels, from local to global.
