Predictions:
- The size of plant is directly related to age.
-The larger a bush gets, the less species will be found beneath it.
-We will find more Lonicera maackii in disturbed areas than in older and more established forests.
-It is harder for new growth to occur once L. maackii has been established in an area.
Experimental Designs:
We will measure 10 2X2 meter plots in different areas of the Oxford area in order to get a large and diverse sample. We will measure the number of individual plants as well as the average height for each individual plot. We are also going to count the number of other species in the plots and classify them into herb, shrub, subcanopy tree, or canopy tree layers.
Bibliography:
1) http://www.dnr.state.oh.us/dnap/invasive/
This site introduced all the invasive species known in Ohio. It also gave background information, eradication mechanisms, and characteristics of invasive plants. This source is important to use in our study because it was geographically relevant, and it was produced by a government agency.
2) http://www.invasivespecies.gov/profiles/japhomey.shtml
This website described a 5-year study that showed the effects of bush honeysuckle's invasion on a native species, which is directly related to what we are investigating. This website provided links to many other sites which go into further detail about distribution, it's invasive habits, growth patterns, and more.
3) Deering, R.H. & Vankat, J.L. (1998) Forest Colonization and Developmental Growth of the Invasive Shrub Lonicera maackii. The American Midland Naturalist.
This journal article discusses the history of the plant in the Oxford area. This article also describes the plant within one plot of forest fragment south of Oxford; although it takes some time for plant to establish, it grows exponentially. This article will contribute to our research because it narrows our information specifically to the Oxford area, and it gave us a good understanding of Lonicera maackii's beginnings here.
4) Hutchinson, T.F. & Vankat, J.L. (1997) Landscape Structure and Spread of the Exotic Shrub Lonicera maackii (Amur honeysuckle) in Southwestern Ohio Forests. The American Midland Naturalist.
This journal talks about honeysuckle's dispersal methods and where it is most commonly found. It also discusses the type of landscape it prefers, and it explains some bird patterns as they relate to seed dispersal. Island biogeography was brought up as a factor in invasion. This article is relevant to our study because it focuses on the Oxford area, and it will help guide us to find where we will most likely find Lonicera maackii.
5) Quigley, M. Sweet-Smelling Forest Threat. American Forests. Autumn, 2002. (Vol. 108, Issue 3) p. 26.
This article provided background information on bush honeysuckle and explained the effects this plant has on others. How Lonicera maackii were introduced into the United States was also mentioned. This article was important to us because it provided a large overview of the species to get us all familiar with our organism under investigation.
