Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.

Answer:
lichens and bryophytes[secondary seccession]
Explanation:
after the wildfire, the area would bee too dry and therfore it'll lead to a xerarch succession. lichens and bryophytes would be the climax communities.
