Additional examples of microevolution documented in natural populations come from studies of
soapberry bugs:

bug: Natural history with the history. Evolution 46: 1052–1069.
Carroll, S. P., H. Dingle, and S. P. Klassen. 1997. Genetic differentiation of fitness-associated traits among rapidly evolving populations of
the soapberry bug. Evolution 51: 1182–1188.

studies of snakes:

adaptive change in a native predator: Cane toads and black snakes in
Australia. Proceedings of the Royal Society of London B 273: 1545–1550.
