Sugarcane (Saccharum spp.) is harvested during a 5-month period (October to March) in the Everglades Agricultural Area (EAA) of south Florida. The genetic and temporal variability of sugarcane sucrose concentration is well established, but sucrose accumulation curves have not been reported for the Canal Point (CP) clones used in Florida since 1977. The objective of this study was to compare suc...

—Since European colonization and subsequent commercialization of Appalachian medicinal and edible plants, millions of kilograms of plant material have been extracted from our forests, with little effort to manage these species as natural resources. Roots and rhizomes of black cohosh, a native Appalachian forest herb, are extensively harvested for treatment of menopausal symptoms. As nearly all ...

Most of the world’s acute hunger and undernutrition occurs not in conflicts and natural disasters but in the annual ‘‘hunger season,’’ the time of year when the previous year’s harvest stocks have dwindled, food prices are high, and jobs are scarce (See Text S1, Note A). Nearly seven out of every ten hungry people in the world, or about six hundred million, are either landless rural laborers or...

Sustainable and successful development of the bioenergy industry strongly depends upon the amount and quality of bioenergy feedstock produced. Switchgrass (Panicum virgatum L.) has been identified as a model lignocellulosic bioenergy crop in the U.S. Information regarding its growth and development is considered critical for making management decisions, production of high quality feedstock and ...

In 1994, its second full production year, field-grown meristemmed 'Black Mitchum' peppermint performed differently than in 1993, when compared with a non-meristemmed treatment in a field trial at the OSU-COARC. The difference between years may be partly attributed to better meeting the fertility and soil moisture needs of meristemmed plants in 1994. Plants were not moisture-stressed near harves...

BACKGROUND To address how natural disturbance, forest harvest, and deforestation from reservoir creation affect landscape-level carbon (C) budgets, a retrospective C budget for the 8500 ha Sooke Lake Watershed (SLW) from 1911 to 2012 was developed using historical spatial inventory and disturbance data. To simulate forest C dynamics, data was input into a spatially-explicit version of the Carbo...

Forest harvest alters natural nutrient cycles, which is reflected in stream water run-off from harvested catchments. Nitrate is an essential nutrient for plant growth, but increased concentrations in rivers, lakes, and oceans have contributed to eutrophication and anoxic conditions. Based on a literature review, we assessed the impact of three different harvest methods—clearcut, patchcut, and s...

Vertical distributions of (36)Cl and (99)Tc are presented from deep and shallow lysimeters above artificially controlled water tables for a 4-yr experiment from 1990 to 1993. Activity concentration profiles were all measured in late summer when a winter wheat (Triticum aestivum L. cv. Pastiche) crop was harvested. After harvest, activity concentrations in different organs of the crop were deter...

Knowledge about recruitment in a population can be critical when making conservation decisions, particularly for harvested species. Harvest can affect population demography in complex ways and this may be particularly true for cooperatively breeding species whose successful reproduction is often linked with complex social dynamics. We currently have a poor understanding of how harvest affects r...
