Genotypic diversity of Armillaria gallica from mixed oak forests in Massachusetts

Armillaria in Massachusetts Forests: Ecology, Species Distribution, and Population Structure, with an Emphasis on Mixed Oak Forests

A genetic mosaic in the fruiting stage of Armillaria gallica.

The basidiome stage of Armillaria gallica can be a genetic mosaic. Ten cells isolated from a single basidiome in 1986 produced nine different genotypes when analyzed for variation at six nuclear loci. Four additional basidiomes collected in 1986 produced mosaic patterns when analyzed for variation at a single nuclear (PCR-RFLP) locus. One basidiome collected in 1993 was not a genetic mosaic bec...

Molecular Identification of Armillaria gallica from the Niobrara Valley Preserve in Nebraska

Armillaria isolates were collected from a unique forest ecosystem in the Niobrara Valley Preserve in Nebraska, USA, which comprises a glacial and early postglacial refugium in the central plains of North America. The isolates were collected from diverse forest trees representing a unique mixture of forest types. Combined methods of rDNA sequencing and flow cytometric measurements of nuclear DNA...

Forest regeneration composition and development in upland, mixed-oak forests.

Advance regeneration in 52 mature mixed-oak stands was analyzed and described. Red maple (Acer rubrum L.) was the most abundant species in the study area. Among oak (Quercus) species, northern red oak (Q. rubra L.) was the most abundant within the Allegheny Plateau physiographic province, whereas chestnut oak (Q. montana L.) was the most abundant within the Ridge and Valley physiographic provin...

Management of mixed oak-pine forests under climate scenario uncertainty

The process-based forest growth model 4C (FORESEE FORESt Ecosystems in a Changing Environment) was used to analyze the growth of a mixed oak-pine stand [Quercus petraea (Mattuschka) Liebl., Pinus sylvestris L.]. The oak-pine stand is typical for the ongoing forest transformation in the north-eastern lowlands. The pine and the oak trees are 104 and 9 years old, respectively. Three different mana...
