The long-standing interest in regenerating oaks stimulated the development of a number of research studies during the past several decades. Most studies have focused on addressing oak regeneration problems and many of these suggested that oak regeneration failures occur where site conditions favor the establishment and growth of competing species that capture the growing space following crown r...

Global warming accelerates decomposition of soil organic carbon (SOC) pools with varying rates and temperature sensitivities. Black carbon (BC) materials are among the slowest decomposing components of the SOC pool. Although BC is a large component of SOC in many systems, the influence of temperature on decomposition of BC bearing different chemical and physical structures remains poorly unders...

Several hurricanes struck Florida, U.S. in 2004 and 2005 causing widespread damage to urban and rural areas. We measured the impacts of five of these hurricanes on the urban forest and combined these results with four other hurricanes to present an assessment of wind resistance for southeastern United States coastal plain tree species. Urban forest loss was positively correlated with wind speed...

The distributions and abundances of birds within oak woodland communities of California are the results of geologic events leading to the formation of the Mediterranean-type ecosystem, and of more recent anthropogenic impacts that have altered the landscape. These human-wrought disturbances to oak woodlands likely are affecting population parameters and distributions of birds throughout Califor...

Although it is well known that fire can exert strong control on stand structure, composition, and dynamics in savannas and woodlands, the relationship between fire frequency and stand structure has been characterized in few of the world’s savanna and woodland ecosystems. To address this issue in temperate oak-dominated ecosystems, we studied the effects of fire frequency on stand structure and ...

Midstoty competition control c nd shoot clipping have been proposed to increase the vigor and height of advance bottomland oak reproduction. Results from a study in east-central Mississippi showed that advance cherrybark oak (Quercus pagoda Raf) releasedfrom midstory competition had greater survival than nonreleased seedlings, 64% and 48%, respectively, 9 yr after treatment. Released seedlings ...

Originally from Germany, Sabine Petry received her Diploma (MSc) from Goethe University in Frankfurt and undertook her Master's thesis at the Max Planck Institute of Biophysics. She then moved to the UK to pursue a PhD under the supervision of Venki Ramakrishnan at the MRC Laboratory of Molecular Biology in Cambridge. In 2008, Sabine started her postdoctoral work in the laboratory of Ron Vale a...

Marvin Tanenbaum performed his undergraduate studies in Biomedical Sciences at the University of Amsterdam in The Netherlands. He obtained his PhD from Utrecht University in 2010 cum laude, having worked with René Medema on microtubule motor proteins. He won the Netherlands Association for Medical Education (NVMO) Oncology and Utrecht University Thesis awards, and moved to San Francisco with an...

Three series of three tests each of Nuttall oak (Quercus texana Buckl. formally Q. nuttallii Palmer) were established by the Western Gulf Forest Tree Improvement Program at three locations: Desha and Lonoke Counties in Arkansas and Sharkey County in Mississippi. The three series included 28-42 different halfsib families from throughout the natural range of Nuttall oak. Families were arbitrarily...
