Nowhere in the world have tree improvement and silviculture had a bigger impact on forest productivity and value to landowners than in the southern US. The economic impact from almost 60 years of tree improvement in the southern United States has been staggering. For example, over 300,000 hectares are planted each year with seedlings from the breeding efforts with loblolly pine (Pinus taeda) by members and staff of the North Carolina State University Cooperative Tree Improvement Program. The present value of continued genetic gains from traditional tree improvement efforts is estimated to be $2.5 billion USD to landowners and citizens in the southern US.

Abstract The effects of fusiform rust on product yields from loblolly pine plantations are modeled in four stages: The additional mortality caused by the disease; additional infection observable after age five (the age from which increased mortality is estimated); a probability density function to describe gall heights on infected stems; and a merchandising routine based on specific milling practice assumptions and merchandising strategies. These processes are then incorporated into the North Carolina State University Managed Loblolly Pine Plantation Growth and Yield Simulator, and the effect of various levels of rust incidence on product yields in unthinned stands simulated. Yield of solid product decreased sharply across plantations with increasing infection. Pulp yields increased because of infected stem components that could only be utilized for this product. South J. Appl. For. 12(4):226-231

Abstract Land expectation values (LEV) of site preparation and release treatments using herbicides in central Georgia are calculated and compared. Loblolly pine growth and hardwood competition levels were measured at age 6 for the site preparation treatments and age 8 for the release treatments. These measurements were projected to final harvest using the North Carolina State University growth and yield simulator. On six directly comparable sites, site preparation improved land expectation values more than release. When the most profitable treatments on each site were compared, site preparation LEVs (after tax) were more than twice as profitable as release ($403 vs. $188/ac). Velpar L¹ and Pronone 10G herbicide treatments increased the land expectation value most for site preparation. Arsenal AC and Velpar L provided the highest returns among the herbicides tested for release. South. J. Appl. For. 22(3):156-162.

Abstract Control-pollinated polymix progenies of 9 slash pine (P. elliottii Engelm.) and 10 loblolly (Pinus taeda L.) pine from some of the best clones in a South African tree improvement program were tested in Georgia. Overall, the progenies of the South African selections in both species have done well after five years in the field. One of the slash pine and three of the loblolly pine families were better than open-pollinated progeny from established seed orchards.

Controlled mass pollination (CMP) is one way to increase genetic gains from traditional wind-pollinated seed orchards. Methodology is under development by several forestry companies in the southern USA. Costs of CMP depend on the efficient installation, pollination, and removal of inexpensive paper bags. Even in pilot-scale studies these costs seem reasonable. Net present values from CMP in a sample of sixty-seven loblolly pine (Pinus taeda L.) seed orchards in the Western Gulf Forest Tree Improvement Program are conservatively expected to average $108 per acre of plantation established with seedlings from CMP among the best six parents in each of five breeding regions and $154 per acre for CMP among the best pair of parents in each breeding region. Key words: supplemental mass pollination, expected genetic gains, pollen contamination

An adult male blue Siamese fighting fish (Betta splendens) presented to the North Carolina State University College of Veterinary Medicine with a cranial mass located dorsal to his right eye. A fine-needle aspiration was performed followed by supportive care. Due to the patient’s small size aggressive treatment was not elected. The mass continued to expand over a course of five months until the patient was found deceased, and a postmortem examination was performed. Histopathology determined the mass to be a chromatophoroma of the iridophoroma or leucophoroma subtypes. This is the first documentation of a chromatophoroma in B splendens.
