Fungi Forage trail in Mexican highlands

 

"A new method for tracking pathways of humans searching for wild, edible fungi" discusses the best way to use GPS to track mushroom foraging behaviour of the Nahua in Mexico. The paper contains a trail of one forager, notice the change in altitude in a 5-hour trek.  
Searching behavior is a fundamental activity performed by organisms in order to increase their probability to survive, grow and reproduce by finding food, refuges or mates. Humans are no exception. Every day we can readily observe how we, consciously or unconsciously, search for and find a great variety of items, an ability that surely has its origins in our evolutionary past, including as hunter-gatherers.
