• Invasive species:
  • Introduction of non-native species can outcompete native species and disrupt ecosystem dynamics.

Slide 12: Alien Species Invasion

  • Disruption of ecosystem processes, such as nutrient cycling.
• Control and management of invasive species:
  • Prevention through strict regulations on importation and transport of species.

Slide 15: Conservation Genetics

• Definition of conservation genetics:
  • Application of genetics to conserve endangered species and preserve genetic diversity.
• Genetic diversity and conservation:
  • Higher genetic diversity leads to better adaptation and resilience of populations.
  • Small population sizes can reduce genetic diversity through genetic drift and inbreeding.
• Techniques used in conservation genetics:
  • Genetic markers (e.g., DNA analysis) to identify individuals, populations, and species.
  • Assisted reproductive technologies, such as artificial insemination and in vitro fertilization.
• Examples of conservation genetic applications:
  • Identifying genetically unique populations for protection.
  • Translocation of individuals to restore genetic diversity.
  • Genetic monitoring to assess the effectiveness of conservation efforts.

Slide 16: Ex situ Conservation

• Definition of ex situ conservation:

  • Captive breeding:
    • Breeding endangered species in captivity for potential reintroduction into the wild.
  • Zoos, botanical gardens, and arboreta:
    • Housing and breeding rare and endangered species for public display and conservation purposes.
• Benefits and limitations of ex situ conservation:
