biodynamic agriculture |
A holistic, ecological, and ethical approach to farming, gardening, food, and nutrition. Biodynamic agriculture has been practiced for nearly a century, on every continent on Earth. Biodynamic principles and practices are based on the spiritual insights and practical suggestions of Dr. Rudolf Steiner, and have been developed through the collaboration of many farmers and researchers since the early 1920s. See also Conservation Agriculture.

A method of controlling pests such as insects, mites, weeds and plant diseases using other organisms.

biological sustainable level (fished within) |
In fisheries organizations, biological sustainable levels are usually defined according to MSY, which is the Maximum Sustainable Yield (or catch) that can be continuously taken from a stock under existing environmental conditions without affecting its reproductive potential. Two key levels are considered: to assess the sustainability of fishing on a given stock: FMSY which is the fishing mortality that is consistent with achieving MSY and BMSY that is the biomass that results from fishing at FMSY for a long time.

any interaction where the action of one species has a beneficial effect on another. This includes mutualistic interactions where both the facilitated and facilitator benefit (+/+), those which are commensal (+/0) when the effects of the facilitated on the facilitator are neutral as well as those which are antagonistic (+/?) when the facilitated negatively impact the facilitator. Note that this concept partially overlaps with that of mutualism, ecological engineering and niche construction

biotic resistance to invasion |
the ability of species in a community to limit the recruitment or invasion of other species (Catford et al., 2009; Levine et al., 2004). It is central to our understanding of how communities at risk of invasion assemble after disturbances, but it has yet to translate into guiding principles for the restoration of invasion-resistant communities

black carbon |
Black carbon is a carbonaceous aerosol. It is produced both naturally and by human activities as a result of the incomplete combustion of fossil fuels, biofuels, and biomass. Primary sources include emissions from diesel engines, cook stoves, wood burning and forest fires. Black carbon particles strongly absorb sunlight and give soot its black color. Thus, black carbon has emerged as a major contributor to global climate change, possibly second only to CO2 as the main driver of change.
