Study Notes
Biodiversity Threats & Conservation Strategies
- Over 45,300 species are threatened with extinction, representing 28% of assessed species.
- Amphibians (41%), mammals (26%), conifers (34%), reef corals (36%), selected crustaceans (28%), reptiles (21%), birds (12%), sharks and rays (37%), and cycads (71%) are among the groups facing threats.
Threat Assessment Criteria
- Extinction risk is assessed using criteria including population reduction, restricted geographic range, small population size, and extinction probability analysis.
- Categories for threatened species include: Critically Endangered (CR), Endangered (EN), Vulnerable (VU), and others.
Carnivorous Plants
- Some plants are carnivorous.
- They adapt to nutrient-poor environments by obtaining nitrogen from animals, especially insects.
- For example, certain Nepenthes species use nectar to attract prey, then the prey gets trapped and digested within the plant.
Integrated Plant Conservation
- Conservation includes in-situ (preserving biodiversity in natural habitats) and ex-situ (conserving outside natural habitats) strategies.
- In-situ strategies involve managing and monitoring tree diversity in natural habitats.
- Ex-situ strategies involve curating tree diversity outside natural habitats through methods like seed banking, cryopreservation, micropropagation, and conservation collections.
- Other strategies include research (reproductive biology, genetics, ecology), horticulture (propagation, cultivation, reintroduction), and education (interpretation, training, awareness-building).
