Abstract. Cities have become increasingly interested in reducing their greenhouse gas emissions and increasing carbon sequestration storage urban vegetation soil as part of climate mitigation actions. However, most our knowledge the biogenic cycle is based on data models from forested ecosystems, despite nature microclimates differing greatly those natural or ecosystems. There a need for modell...

Funding Request: No funding is requested. We are not continuing this project because of the current low level of the disease in most commercial orchards and lack of interest in the industry in funding a full program on this disease. However, as the acreage of new plantings increases, particularly those susceptible varieties, bacterial canker can be an important factor in the process of establis...

Prior to the 2000 planting season, some industry obsemers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers t...

A serious crown and stem disease of fibrous-rooted begonia {Begonia semperflorens Link and Otto) plants, variety Fire Sea, was observed in out-of-door plantings at Berkeley, Calif., in July 1937. During the following winter, a similar disease was found on Carmine, Christmas Cheer, and Primadonna fibrous-rooted begonia plants in a greenhouse at Columbia, Mo. A preliminary report on this disease ...

The creation of artificial plantings in the conditions kovylno-tipchak steppe makes it possible to form long-lasting high-density and productive plantings, however, despite accumulated knowledge, rate afforestation is hindered by fleeting or delayed death due effects droughts. Fast-growing young trees become especially vulnerable areas with deep groundwaters. study was conducted green zone Asta...

Abstract Anthropogenic disturbances lead to the degradation or destruction of tropical forests, with negative consequences for flora, fauna, and local people. Restoration plantings may compensate these impacts, but time financial expenditures are high. Thus, priority is often given plantations a few introduced species that have little value conservation. Animal seed dispersal diversify accelera...
