Mohr also noted that "sand hills near Montgomery" had openings with several distinctive xerophile
or annual grasses (Aristida, Eragrostis, Panicum) and herbs, including Brickellia eupatorioides, Croptilon divaricatum, Mirabilis sp.
The advance of glaciers in temperate regions at different periods resulted in the development of xerophile
formations, such as savannas, in tropical and subtropical areas (Raven and Axelrod, 1974; Goldblatt, 1978; Siffedine et al., 2004; Pennington et al., 2006).
At this period, palaeoenvironment and climate of the Lodeve basin were probably the following: periodic or episodic strong rain falls, temporary water filled channels contain mass occurences of xerophile
organisms (Conchostracans, Triopsids, Insects).
During storage, xerophile
fungi can invade numerous substrates, even dry salted fish.
