We report on growth and survivorship of two cohorts of blue oaks Quercus douglasii Hook. & Arn. (Fagaceae) monitored at Hastings Reservation in Monterey County, California, the first growing in an unprotected old field and measured as seedlings in 1965 and the second planted as acorns in 1985 in several sites differing in their degree of protection from grazing. Growth of all individuals was ex...

Two apparently unlinked events marked the beginning of one of the most devastating forest diseases known to man in recent times: Sudden Oak Death (SOD). In the mid 1990s, while a novel species of Phytophthora was being isolated from mildly diseased Rhododendron and Viburnum plants in German and Belgian nurseries, the first reports of inexplicable death of tanoaks (Notholithocarpus densiflorus) ...

Crop rotation and fallow are management options that can be used to control plant parasitic nematodes in forest tree nurseries. Before these options can be put into practice, it is important to determine the host range and survivability under fallow of the parasitic nematode to be controlled. The results of host range tests on a needle nematode (Longidorus spp.) and a stunt nematode (Tylenchorh...

Adaptive divergence is widely accepted as a contributor to speciation and the maintenance of species integrity. However, mechanisms leading reproductive isolation, genes involved in adaptive divergence, traits that shape adaptation wild changes climate are still largely unknown. In studying role ecological interactions environment-driven selection, trees have emerged potential model organisms b...

An ensemble modelling approach was performed to predict the distributions of seven sympatric sclerophyllous oak species in Hengduan Mountains Southwest China. Spatial eigenvector filters revealed missing factors addition commonly used environmental variables, thus effectively improved predictive accuracy for montane species. This study identified a richness center oaks, which provides reference...

Alteration of the fire regime in upland oak–hickory (Quercus L. spp.–Carya Nutt. spp.) forests Central Hardwood Region is a major factor for current shifts species’ composition and oak recruitment regeneration failures. The reintroduction into these ecosystems requires better understanding effects on co-occurring competitors. First-order (i.e., during immediately after) red maple (Acer rubrum L...
