abstract = {In tropical lowland forests, corticolous crustose green
algal lichens are abundant and highly diverse. This may be
related to adaptation to prevailing microenvironmental
conditions including, for example, high precipitation and
low light intensities. In the understory of a tropical
lowland rain forest in French Guiana, we studied the
morphology of crustose green algal lichens and measured gas
exchange and chlorophyll a fluorescence. We found that (i)
periods of thallus suprasaturation with water were reduced
by the presence of water-repelling surface structures of
mycobiont hyphae at the thallus surface and the medulla;
(ii) photosynthesis was adapted to the low light intensities
present in the understory; and (iii) photosynthesis was
rapidly activated in fluctuating light. The combination of
these three mechanisms enables corticolous lichens to
implement specific morphological and physiological
strategies, which may favour growth in the limiting
understory habitat of tropical lowland rain forests.},
