Brockmann's research on animal behavior spans different groups in the animal kingdom. She has examined
kleptoparasitism in birds, the mating and nesting tactics of wasps including investigations into the mud-daubing wasp
Trypoxylon politum and a digger wasp (
Sphex ichneumoneus). In beetles, she has examined sexual selection in
Diaprepes abbreviatus which is important in Florida because it causes problems with citrus crops. Her research on behavior and population biology of horseshoe crabs is conducted at
Cedar Keys National Wildlife Refuge, and includes addressing the question of why females select their nesting sites and the nesting tactics of males. She has also used genetics to define genetically distinct groups of horseshoe crabs in Florida and along the east coast of the United States.
