Sensitivity of Texas strains of Ceratocystis fagacearum to triazole fungicides

Ten geographically diverse Texas strains of the oak wilt fungus Ceratocystis fagacearum were tested in vitro for their sensitivity to five triazole fungicides based on accumulated linear growth, linear growth rates, and dry weight accumulation in response to fungicide concentrations of 0.1 to 600 parts per billion (ppb). None of the triazoles inhibited growth at 0.1...

Limited evidence of declining growth among moisture-limited black and white spruce in interior Alaska

Boreal forests play critical roles in global carbon, water and energy cycles. Recent studies suggest drought is causing a decline in boreal spruce growth, leading to predictions of widespread mortality and a shift in dominant vegetation type in interior Alaska. We took advantage of a large set of tree cores collected from random locations across a vast area of interior...

On valuing patches: estimating contributions to metapopulation growth with reverse-time capture-recapture modeling

Metapopulation ecology has historically been rich in theory, yet analytical approaches for inferring demographic relationships among local populations have been few. We show how reverse-time multi-state capturerecapture models can be used to estimate the importance of local recruitment and interpopulation dispersal to metapopulation growth. We use 'contribution...

Lindera melissifolia responses to flood durations and light regimes suggest strategies for recovery and conservation

Passive management to preserve endangered plant species involves measures to avoid anthropogenic disturbance of natural populations, but this approach may not sustain plants that require disturbance-maintained habitats. Active management is often necessary to maintain existing habitats or provide new habitats for endangered species recovery. Our objective was to...

Growth, yield, and disease resistance of 7- to 12-year-old poplar clones in the north central United States.

Summarizes growth, yield, and disease resistance of 95 poplar clones at or near rotation age (culmination of mean annual increment). Plantations were established from 1986 to 1992 in Wisconsin, Minnesota, North and South Dakota. Clones DN164, DN177, DN154, NM2, NE264, DN170, and DN21 are recommended for further testing.

Field performance of Populus expressing somaclonal variation in resistance to Septoria musiva

Over 1500 trees from two hybrid poplar clones regenerated from tissue culture and expressing somatic variation in leaf disease resistance in a laboratory leaf disk bioassay were field-tested for 5-11 years to examine their resistance to Septoria leaf spot and canker and to assess their growth characteristics compared with the source clones....

North Carolina's forests, 2002

In 2002, forests covered 18.3 million acres in North Carolina, of which 17.7 million were classified as timberland. Hardwood forest types prevailed on 72 percent of timberland and planted pine stands occupied 15 percent. Nonindustrial private forest landowners controlled 78 percent of timberland, forest industry holdings declined to 8 percent, and publicly owned...

Forest statistics for southeast Georgia, 1988

Since 1981, area of timberland in Southeast Georgia increased less than 1 percent and now totals 7.2 million acres. About 39 percent of the timberland is under forest industry control. Pine plantation acreage increased by 37 percent to 2.5 million acres. New pine stands were established annually on 155,000 acres, exceeding pine stands harvested by 4 percent. Number of...

Virginia's forests, 1992

Since 1986, area of timberland in Virginia declined by 1 percent and currently totals 15.4 million acres. Nonindustrial private owners control 77 percent of the State's timberland. Volume of softwood growing stock increased 6 percent to 6.6 billion cubic feet, and hardwood growing-stock volume was up by an equal rate to 19.8 billion cubic feet. Softwood net...

The state of South Carolina's forests, 2001

Forest land area in South Carolina amounted to 12.4 million acres, including 12.2 million acres of timberland. Nonindustrial-private timberland amounted to 8.9 million acres, a decline of less than 1 percent since 1993. Family forest owners dominate the private ownership group with 357,000 landowners who collectively control 7.1 million acres of forest land in the...

Georgia's forests, 2004

Between 1997 and 2004, the Forest Service, Forest Inventory and Analysis Program conducted the eighth inventory of Georgia forests. Forest land area remained stable at 24.8 million acres, and covered about two-thirds of the land area in Georgia. About 24.2 million acres of forest land was considered timberland and 92 percent of that was privately owned. Family forest...

Control of clavicipitaceous anamorphic endophytes with fungicides, aerated steam and supercritical fluid CO₂-seed extraction

The effects of soil drenches with systemic fungicides on viability of clavicipitaceous anamorphic endophytes, non-choke inducing endosymbiotic fungi of the genus Neotyphodium that systemically infect grasses, were tested in endophyte-infected seedlings of Hordeum brevisubulatum subsp. violaceum, Lolium perenne...
