Q

eastern ohio

A

underlain predominatently by sandstone, a relatively resistant rock, underlain by shale to the west. Deep valleys, but not in wearing away the intervening higher land, forming a landscape of steep-sided sandstone hills.

Q

What were the results obtained regarding the appalachian gametophytes?

A

Bayesian analysis of the 56 recovered DET1 alleles yielded a phylogenetic tree that was mostly consistent with the plastid tree.

The teays river system.

29
Q
A

black locust

30
Q

If the closest relatives of V. applachiana are n=120, there would be a second most parsimonious explanation, this one:

A

divergent speciation

31
Q

Shield shaped leaf scars with numerous bundle scars arranged in a “U”. large brown pith, and smell like rancid peanut butter. False end bud. Has a tip scar – a small circular scar lacking bundle scars.

36
Q

Western ohio

A

underlain by limestone (broad areas of its magnesium containing variety, dolomite) it is relatively nonresistant in this humid climate, worn down to comparatively flat landscape.

Q

Name 5 species of trees/shrubs that have a distribution generally limited to high-lime, clay-rich substrates developed in the thick glacial till of western Ohio.

A

sugar maple

beech

shagbark hickory

white oak

white ash

44
Q

…and instead points to an origin involving:

A

Genome duplication and/or divergent speciation.

45
Q

What did they find of the two closely related gametophytes?

A

They are not monophyletic

46
Q

homosporous

A

spores all the same produce bisexual gametophytes, in many ferns and lychophytes. no seed plants.

47
Q
A

arrow leaved aster

48
Q

Referring to the appalachian gametophyte, what was their question?

A

Are they derived from hybridization? (V. appalachiana)

49
Q
A

black locust

50
Q
A

tulip tree

51
Q
52
Q
A

american beech

53
Q
54
Q

Alternate leaf arrangement. Buds are hidden beneath leaf scars, saplings produce paired stipular spines. Tall old trees lack spines.

A

black locust

55
Q
A

sneezeweed

56
Q
57
Q

If the closest relatives of V. applachiana turn out to be n=60 then the most likely explanation would be this:

A

genome duplication

58
Q
A

pilewort/fireweed

59
Q
A

sawtoothed sunflower

60
Q

western ohio substrate

A

67
Q

Twigs are stout with a true terminal bud, and 3-lobed leaf scars that look like a monkeys face. Twigs have a chambered pith (hollow with cross walls)

A

Black Walnut

68
