The objectives of this research project are to understand tannin and anthocyanin changes during berry development in Pinot noir fruit and wines. Specifically, the objectives of this research project are:
· Determine the effect of berry development on the composition of tannins in cv. Pinot noir berries
· Determine the...
Rubus seed has a deep double dormancy that restricts germination due to seed coat structure and chemical composition. Improved germination of diverse Rubus species required for breeding improved blackberry and raspberry cultivars is partly dependent on the seed coat structure. This study evaluated the seed coat structure of three species...
The objectives of this research are to monitor tannin and anthocyanin changes during berry development and over several growing seasons to understand how the vintage effects wine composition. Specifically, the objectives of this research project are :
· Determine the effect of berry development on the composition of phenolics (tannins...
Little is known about the impact of temperature on proanthocyanidin (PA) accumulation in grape skins, despite its
significance in berry composition and wine quality. Field-grown grapes (cv. Merlot) were cooled during the day or
heated at night by +/–8 C, from fruit set to veraison in three seasons, to determine...

"... One goal of this document is to synthesize the literature on the effects of mechanical thinning on understory plant species. A second goal is to document the effect of prescribed burning on rare, threatened, or endangered species. We review current literature on studies that address effects of prescribed fire...
Across the western US, the two most prevalent native forest insect pests are mountain pine beetle (MPB; Dendroctonus ponderosae; a bark beetle) and western spruce budworm (WSB; Choristoneura freemani; a defoliator). MPB outbreaks have received more forest management attention than WSB outbreaks, but studies to date have not compared their...
The ex-vessel supply chain for fisheries has been recognized as an important determinant of value generation. In recent years, as the retail demand for fresh seafood products has increased, many independent fishermen have bypassed thin, monopsonized, or otherwise inferior wholesale markets by engaging in implicit or explicit fixed-output contracts with...
Intrinsic and extrinsic factors affect vital rates and population-level processes, and understanding these factors is paramount to devising successful management plans for wildlife species. For example, birds time migration in response, in part, to local and broadscale climate fluctuations to initiate breeding upon arrival to nesting territories, and prolonged inclement...
Management in fire-prone ecosystems relies widely upon application of prescribed fire and/or fire surrogate (e.g., forest thinning) treatments to maintain biodiversity and ecosystem function. Recently, published literature examining wildlife response to fire and fire management has increased rapidly. However, none of this literature has been synthesized quantitatively, precluding assessment of...
Livestock grazing is a widespread source of habitat modification, and may affect populations of ground-nesting grassland birds by influencing rates of nest failure. Nesting attempts can fail for various reasons, and determining risk of failure from specific causes associated with livestock grazing would enhance development of range management practices in...
In the late 1850s, few young Jews, recently arrived in the United States from Poland, chose to live in Florida. Fortunately, one who did, Max White, wrote down his memoirs of those years, leaving us a remarkable, very personal account of life on the Florida frontier as well as a...
In 2006–2010, effects of four different cattle stocking rates (0, 14.4, 28.8, and 43.2 animal unit months) were compared, representing 0%, 20%, 32%, and 46% utilization of vegetation by domestic livestock, on vegetation structure (as indexed by visual obstruction), and songbird population and apparent nest density, community composition, and diversity...
Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests...

Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...
