Abstract Detail



Ecological and evolutionary attributes of bryophytes of the boreal and arctic regions: New paradigms from interdisciplinary research

Frego, Katherine A. [1], Fenton, Nicole [2], Ross-Davis, Amy [3].

A new paradigm for bryophyte ecology: The critical roles of dispersal and the juvenile phase.

Studies of the factors governing bryophyte community assembly have tended to focus on ranges of ecological tolerance of the established gametophore at the microsite level, as well as interactions such as competition at the same scale. The roles of spore dispersal and establishment of the juvenile protonemal stages have rarely been considered, with two underlying assumptions: that airborne spores are randomly and uniformly available, and that the ecological tolerance of juveniles is similar to that of adult gametophores. We present evidence for a new paradigm, that the dispersal and juvenile establishment phases play a critical role in community assembly, and outline the studies required to test this and more refined hypotheses.
