Survival and Initial Growth Attributes of Improved and Unimproved Cherrybark Oak in South Arkansas
SURVIVAL AND INITIAL GROWTH ATTRIBUTES OF IMPROVED AND UNIMPROVED CHERRYBARK OAK IN SOUTH ARKANSAS Joshua P. Adams, David Graves, Matthew H. Pelkki, Chris Stuhlinger, and Jon Barry1 Abstract--Thousands of acres are planted every year with genetically improved seedlings; but while pine continues to be extensively explored, the same is not true for hardwoods due to costs and rotation length. An improved cherrybark oak (Quercus pagoda Raf.) seed orchard exists in North Little Rock, AR, providing an opportunity to evaluate hardwood improvement. However, the cost and limited testing of these seedlings have been large limiting factors in their deployment. In February 2012, improved and woods-run seedlings were hand-planted at two sites in southern Arkansas including a site near Hope, AR, and one near Monticello, AR. The sites were treated with 2 ounces per acre of Oust XP® 2 weeks after tree planting with manual control of sumac (Rhus spp.) and sweetgum (Liquidambar styraciflua L.) shortly thereafter. A random sample of seedlings at the nursery confirmed that seedling undercutting effectively controlled root length which was statistically the same for both groups at 21.8 inches. However, root collar diameter of an improved seedling was on average 27 percent larger than an unimproved seedling. These trends were similar to those among planted seedlings in which improved seedlings were 9 percent and 8 percent greater in regards to ground line diameter and height, respectively. However, improved seedlings exhibited greater initial mortality, by 6.2 percent, in the first few months of their growing season. While initial mortality is often considered random, disparity between the two groups points to other causes, such as the larger root sizes, which may pose planting problems. -

Designing Hardwood Tree Plantings for Wildlife Brian J
FNR-213 Hardwood Tree Improvement and Regeneration Center North Central Research Station USDA Forest Service Department of Forestry and Natural Resources Purdue University Designing Hardwood Tree Plantings for Wildlife Brian J. MacGowan, Department of Forestry and Natural Resources, Purdue University Woody plants can be of value to many wildlife species. The species of tree or shrub, or the location, size, and shape of planting can all have an impact on wildlife. The purpose of this paper is to discuss the benefits of trees and shrubs for wildlife and how to design tree and shrub plantings for wildlife. Some of the practices may conflict with other management goals and may have to be modified for individual priorities. Trees and Shrubs for Wildlife The species you select for a tree planting should depend on the growing conditions of the site and the wildlife species that you want to manage. Talk to a professional forester to help you select the tree species best suited for your growing conditions. A professional biologist, such as a Department of Natural Resources District Biologist (www.in.gov/ food source for wildlife (Table 2). Shrubs can be dnr/fishwild/huntguide1/wbiolo.htm), can assist you particularly important because several species of with planning a tree planting for wildlife. wildlife, especially songbirds, prefer to feed or nest There is no specific formula for developing wild- on or near the ground.

(May 2007) Geoffrey Carlile Denny, B.S., Texas A&M University; M.A., The University of Texas Chair of Advisory Committee: Dr. Michael A. Arnold Taxodium distichum (L.) Rich. is a widely adaptable, long-lived tree species for landscape use. It is tolerant of substantial soil salt levels, but tends to defoliate in periods of extended or severe drought, when leaves come into contact with salty irrigation water, and tends to develop chlorosis on high pH soils. The purpose of this research was to identify provenances which may yield genotypes tolerant of these stresses. The appropriate name for baldcypress is Taxodium distichum (L.) Rich. var. distichum, for pondcypress is T. distichum var. imbricarium (Nutt.) Croom, and for Montezuma cypress is T. distichum var. -

A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere. -
IDENTIFYING OAKS: the HYBRID PROBLEM by Richard J
. IDENTIFYING OAKS: THE HYBRID PROBLEM by Richard J. Jensen I Anyone who has spent time trying to identify oaks (Quercus spp.), especially in the for ests of eastern North America, has encountered trees that defy classification into any of the recognized species. Such trees commonly are treated as putative hybrids and often are taken as evidence that species of oaks are not as discrete as species in other groups. On the other hand, some (e.g., Muller, 1941) have argued that many, if not most, putative hybrids are nothing more than stump sprouts or aberrant individuals of a species. Muller (1941) did not deny the existence of hybrids; he was cautioning against an inflated view of the frequency of hybridization as a result of cavalier claims. As he put it (Muller, 1951), 'The freedom of hybridization ascribed to oaks is immensely overrated." While I don't disagree with these sentiments, I do believe that hybrids are a common component of forests throughout North America. Virtually all oak species in North America have been claimed to produce hybrids with one or more related species. Hardin (1975j presented a diagram illustrating hybrid combina tions for the common white oak (Quercus alba L.) and Fig. 1 provides a similar view for northern red oak (Quercus rubra L.). Because these two species have very broad geo graphical ranges and come in contact with a large number of related taxa, there is ample opportunity for hybrid combina- RUB tions to arise naturally. These two examples also reflect the fact that MAR coc instances of hybridization are re stricted to taxa within a section: Quercus section Quercus (the white and chestnut oaks) and ELL IU Quercus section Lobatae (the red and black oaks), respectively. -
