This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.
Psychophiles are bacteria can grow and survive in really low temperatures. These organism are adapted to freezing temperatures by producing antifreeze proteins that protect the organisms from vetrification and dessication. Examples of psychophilic bacteria that can contaminate food include Aeromonas spp and Yersinia spp
