“Fumed” Oak and Natural Brown Oak

MECHANISMS OF OAK DISPERSAL Acorn Characteristics and Oak Dispersal

INTRODUCTION Although oaks dominate many forest ecosystems worldwide (Barnes and others 1998), several aspects of oak ecology remain poorly understood including oak regeneration and masting (McShea and Healy 2001). Animals that eat and disperse acorns, such as squirrels, mice, and jays may play a pivotal role in oak forest dynamics (Jones and others 1998, Ostfeld and others 1996), influencing r...

Oak Shelterwood: A Technique to Improve Oak Regeneration

Oak Regeneration Dynamics Successful regeneration of oak on intermediate and high-quality sites (upland oak site index > 65 to 70 feet) is limited due to the lack of the vigorous advance regeneration and/or saplings/pole-sized trees that are capable of sprouting. Vigorous advance regeneration and/or stump sprouters are required at the time of regeneration on intermediate and highquality sites, ...

Natural regeneration of sessile oak under different light conditions

Different variants of regeneration felling or different light conditions (total site factor 15–95%) and weed control were evaluated in relation to the 4-year development of individuals of regenerated sessile oak. The regeneration density is not dependent on light conditions. The highest mortality occurs on the open area of clear felling. For a certain time in youth, it is possible to consider o...

Oak - Bark Tannins

1. The colorimetric method for estimation of acetoacetate by reaction with diazotizedp-nitroaniline has been adapted for measurements of oxaloacetate in amounts of 0 003-0 03 Htmole. 2. The steady-state level of oxaloacetate in the livers of normal and fasted rats was found to be about 4 umoles/100 g. dry wt. of tissue. The level was essentially unchanged in starvation when the level of acetoac...
