“the three phylogenetic analyses supported the genus Phaeomegaceros as monophyletic”

Claim · model-written summary

Phaeomegaceros comprises New Zealand and Austral American clades differing in a spore-face depression.

Taxon

Organ / stage

Setting

Verbatim

e0

“Phaeomegaceros is composed of two major clades corresponding to the New Zealand species, which presents a conspicuous trilete mark with one depression in the middle of the spore’s proximal face, and the Austral American species, which lack this middle depression.”

Claim · model-written summary

The authors speculate that Antarctic climatic fluctuations isolated Phaeomegaceros taxa through dispersal and vicariance.

Taxon

PhaeomegacerosPhaeomegacerose0

Outcome

isolation of Phaeomegaceros taxae0

Qualifier

dispersal events and vicariancee0

Setting

Antarctic continente0

Verbatim

e0

“climatic fluctuations in the Antarctic continent during the middle to late-Miocene led to the isolation of Phaeomegaceros taxa with both processes (dispersal events and vicariance) acting on the independent evolution of the disjunct clades”

Claim · model-written summary

The authors attribute recent Austral American diversification and range expansion to dispersal and cladogenesis associated with geological changes.

Taxon

PhaeomegacerosPhaeomegacerose0

Outcome

recent diversificatione0

Qualifier

dispersal events and subsequent cladogenesise0

Setting

Austral Americae0

Verbatim

e0

“recent diversification of Phaeomegaceros taxa in Austral America and range expansion to northern Andes and oceanic islands, are explained by dispersal events and subsequent cladogenesis coinciding with the uplift of the Andes and the formation of volcanic oceanic islands (Juan Fernandez and Tristan da Cunha)”
