Inflated wood frog (Lithobates sylvaticus) lung containing flatworms (trematodes) and roundworms (nematodes). The worms occupy separate niches in the cavity of the lung to avoid competition for space and nutrients from the host.

Yemisi Dare manages the care, organization and use of the invertebrate collections comprising annelids (such as leeches and earthworms), molluscs (including snails, squid and clams), crustaceans (e.g., crabs, shrimp and barnacles), non-insect arthropods (e.g., centipedes and millipedes), and a wide-range of other invertebrates, including parasites. These collections represent about 620 thousand sample lots and no less than 6.8 million specimens. She also is in charge of collection records and documentation, processing loans and acquisitions, and she contributes to exhibition development. Yemisi enjoys working closely with other experts at the museum and other institutions on various research projects and responds to a wide range of information requests. She also trains and manages staff, students and volunteers in collection care.

With over 15 years of research experience, Yemisi's studies have focused on host-parasite dynamics and trends in disease transmission. She has examined behavioural and biological drivers of variation in the patterns of parasitism that we observe in nature. Her expert knowledge of a wide range of taxa have lead to a variety of research initiatives including surveillance programs to monitor patterns of disease among animals and humans in North America, impact assessments of metal poisoning on parasite loads of arctic shore birds, and surveys of parasites in large carnivores (cougars) in the Canadian prairies.
