The Importance of Invertebrate Biodiversity

Invertebrates—while understudied and under-sampled—comprise over 90% of animal life on Earth. They are an exceedingly heterogenous 'group,' from parasitic worms to lobsters. This module covers the numerous diverse values invertebrates have for humans and ecosystems in general, as well as the threats they face. Invertebrate conservation also has several unique challenges, including taxonomic impediments, lack of species-level information (vs. community level), and lack of concern/public interest derived from a "poverty of riches." Case study and critical thinking textboxes enhance the model and provide opportunities for further discussion. Accompanying exercises have students explore aspects of invertebrate ecology, economics, and human perceptions.
