Immortal Mosses Discussion

I’m working on a Biology question and need guidance to help me study.

Read these scientific articles about Bryophyte regeneration in Antarctica and the Canadian Arctic:

La Farge et al. 2013.pdf


Convey et al. 2014.pdf


FYI: The two articles linked below (in Popular Science and National Geographic) have less technical descriptions of these studies. (Links to an external site.) (Links to an external site.)

After reading, consider these guiding questions when forming your responses for this class discussion, or come up with your own talking points:

How do the two above papers relate to what you have learned in class this week? (Hint: What is a Bryophyte? What is a non-vascular plant? What is desiccation tolerance? What does it mean to be poikilohydric?)

Do you have any thoughts pertaining to the viability of the results? Are there flaws in the methodology (Ex: could spores from younger mosses have contaminated the samples)? Why or why not?

What is the ecological importance of Bryophytes in the polar regions?

What do you find most interesting about the researchers’ findings?
