This literature review summarizes the state of current information on the extraction, synthesis, properties, and potential uses of juglone, a natural product produced by the walnut tree (Juglandacea). Juglone (5-hydroxy-1,4-naphthoquinone) is known primarily for its allelopathic effect against certain plants and toxicity towards marine organisms. It has a wide variety of potential uses in medicine, and as a biocide for organic farming and pest control. This summary also provides historical uses of juglone and the walnut tree, a brief background on the biosynthesis and mode of toxicity of juglone. We further go on to recommend and outline the most common methodologies for extraction of the compound in the academic and small industrial setting.

Diffuse and spotted knapweed (Centaurea diffusa Lam and C. stoebe L.) are two closely related invasives found in many parts of British Columbia’s Southern Interior, causing substantial economic losses in rangelands. Beginning in 1970, the provincial government initiated a long-term biological control effort against the knapweeds, introducing 10 different insect agents from 1970 to 1987. In an effort to evaluate the efficacy of the program, archival (1983–2008) data was amassed from 19 vegetation monitoring sites that contained knapweed. In 2010, these sites were relocated and re-monitored and cover values were analyzed. Diffuse knapweed showed significant declines at 14 of 15 sites; spotted knapweed declined at three of four sites. Possible alternative explanations for the decline are discussed. Evidence strongly points to a suite of biocontrol agents (seed feeders and root feeders) as the primary drivers of knapweed decline in British Columbia’s Southern Interior.

People have tried to understand ecosystems using many different models. As a result, the concept of ecosystem-based fishery management is evolving and has no universal definition or consistent application. The objective of this paper is to provide a review of the concepts and ecological economic models related to ecosystem-based fishery management. The paper starts by reviewing basic concepts related to ecosystems and ecosystem-based fishery management. It then reviews economic models for ecosystem-based fishery management that are consistent with the reviewed concepts. The paper finishes off with some conclusions derived from previous literature reviews. We find that there is widespread agreement about the need to implement ecosystem-based fishery management even though this concept has no universal definition or consistent application. We also reveal that nutrient flow plays a crucial role in an ecosystem and that nutrients may be seen as the currency in ecological economic models for ecosystem-based fishery management.
