Deep Woods, the Appalachian Gametophyte, and Ohio Geobotany:

Field Trip Make-up: 9/21

Mini Assignment: Find Two Species of Oak.
  1. Red OakQuercus rubra
    1. Features: Bristle-tipped leaves with a wavy complexion. twigs terminate with a cluster of buds.
    2. Natural History: Known as a major timber tree, used for railroad ties, beams, furniture, and much more.
  2. White OakQuercus alba
    1. Features: Lobed leaves, slight white color on the bottom said of the leaf. The widest part of the leaf is in the middle with the largest lobes.
    2. Natural History: Like Red Oak, White Oak is used for it wood quality as well.

** The article “Linking Geology and Botany: a new approach” by Jane Forsyth mentioned both the White Oak and the Red Oak as species that are commonly found in western Ohio, but both were found in the eastern part at Conkle’s Hollow.

Four Plants of Acidic Sandstone Environments:

Location: Conkle’s Hollow Trails

  1. Tsuga canadensis. Commonly known as: The Eastern Hemlock

    1. The Eastern Hemlock is they most common tree that I had come across along the trail. It is common for then to grow in very shaded areas, like the forest at Conkle’s Hollow. It belongs to the conifer family and is known for it poor wood quality and easily falling leaves.
  1. Oxydendron arboretum. Commonly known as: Sourwood
    1. Sourwood is a small tree with alternately arranged, entire leaves. The tree normally has straight and slender trunks. It is found in areas of full sun.
  2. Pinus virginiana. Commonly known as: Scrub Pine 
    1. Often grows in poor nutrient, sandy soils. The roots are home to a fungus that is essential for the tree to fully grow, without the fungus the trees often die. This tree is often used for reforestation.
  3. Acer rubrum. Commonly known as: The Red Maple

    1. Commonly found in moist areas and woodland. The tree is able to grow throughout a variety of environments but thrives best in areas with good drainage, poorly grown in heavy clay soils.

 

New Addition of the Appalachian Gametophyte:

Based on the “Unraveling the Origin of the Appalachian Gametophyte” (Pinson and Schuettpelz, 2016)

  1. This gametophyte was found under some of the large rocks that created the pathways for the trails at Conkle’s Hollow. Most commonly found rocks remain moist and sunlight is minimal. Because of the lack of sporophyte, the Appalachian gametophyte must reproduce asexually in which water plays an important helping role. I believe that this gametophyte is Vittaria appalachiana
