Data and code for "Resource gradients drive the distribution and photobiont characteristics of two lichen species in a subarctic lava field" ...
This project described how the distribution and morphology of two species of lichen varied along a transect perpendicular to Lake Myvatn in Iceland. All data were collected in a recent (1729) lava field and we focused on two species Flavocetraria cucullata and Peltigera leucophlebia. Lake Myvatn is...
