Explore the intricacies of biodiversity maintenance in nature through a comprehensive lecture using the wood tiger moth as a case study. Delve into Darwin's problem, aposematism, and color polymorphism, examining frequency-dependent survival on a global scale. Investigate predator-prey interactions, bird composition effects, and context-dependent frequency-dependent survival in Central Finland. Analyze bird avoidance responses, the impact of bird experience, and relative fitness in offspring. Examine spatial models, dispersal in sexual organisms, and movement patterns through mark-recapture analyses. Gain insights into the wood tiger moth's color genetics and global polymorphism distribution, culminating in a proposal integrating genetics and selection across life stages.

    It was a great learning. I really enjoyed learning why is it crucial to maintain diversity in nature. Your research gave valuable insights on the topic. I got to know how nature and its organisms adapt themselves accordingly to cope up with conditions and predators. Truly biodiversity is interesting.
