About 95% of swamp tupelo (Nyssa sylvatica var. biflora (Walt.) Sarg.) and sweetgum (Liquidambar styraciflua L.) seedlings survived continuous root flooding for more than two years, whereas none of the swamp chestnut oak (Quercus michauxii Nutt.) and cherrybark oak (Q. falcata var. pagodifolia Ell.) seedlings survived one year of flooding. Death of oak seedlings occurred in phases associated wi...

the effect of grape pomace (vitis vinifera) and in oak leaf (quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (omd) and in situ dry matter (dm) and crude protein (cp) disappearance were studied in four sheeps. polyethylene glycol (peg) was used to deactivate the tannins. in vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...

We analyze interannual to multi-decadal growth variations of 555 oak trees from Central-West Germany. A network of 13 pedunculate oak (Quercus robur L.) and 33 sessile oak (Quercus petraea (Matt.) Liebl.) site chronologies is compared with gridded temperature, precipitation, cloud-cover, vapor pressure and drought (i.e., Palmer Drought Severity Index, PDSI) fluctuations. A hierarchic cluster an...

An individual tree basal area increment model was developed for blue oak (Quercus douglasii Hook. & Arn.) in California, an important woodland tree for wildlife habitat. Box-Cox regression based on 895 increment cores that showed current basal area and the relative size of the tree crown were significant variables. Models to link basal area changes over time with tree height and crown cover wer...

With the reemerging discussion of gentrification in the urban landscape, an exploratory case study of the Oak Park Redevelopment Plan in Sacramento, California, was conducted to better understand the community’s gentrifying characteristics and the implications once the redevelopment goals are met. In addition, a conceptual framework (CF) was formulated in order to examine the components and pro...

Proper protocol for mycorrhizal inoculation of container grown landscape trees is uncertain. Therefore, vegetative and commercial spore inoculum of Pisolithus tinctorius were applied to Quercus palustris (pin oak) and Q. coccinea (scarlet oak) seedlings. All plants were grown in containers filled with 0.9 liters of milled pine bark, sterilized milled pine bark, sterilized mineral soil, or steri...

Severe bark decay disease was observed on oak logs at a shiitake cultivation farm in Geochang-gun, Gyeongnam province. The symptoms observed were fruiting bodies that had developed on the top and side surface of oak logs. As a result, the bark came off easily exposing the sapwood. Slime mold specimens collected from oak logs showed developing fruiting bodies comprising of stalks, hypothallus, c...
