Biological markets and more .... a personal site

What's new?

26 SEP 2021: added a number of recent references to the page cleaning mutualisms

12 SEP 2021: added a reference to a paper by Caselli et al (2021; Behavioral Processes) on grooming and infant handling in geladas to the page grooming in primates. This carefully written paper also reminded me to add a note to my text on 'baby markets'.
