Biodiversity

The variety of life on Earth, encompassing all plants, animals, fungi, bacteria, and other organisms, including their ecosystems and genetic diversity.

Threats to Species

Factors that negatively impact species populations, leading to decline or even extinction.

IUCN

The International Union for Conservation of Nature, a global organization dedicated to conserving nature and its resources.

Conservation Strategies

Strategies and actions taken to protect and manage species and their habitats, aiming to prevent extinction and ensure their long-term survival.

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).
