	Kearneysville, West Virginia : People & Places
		Particle film technological development was expedited by the involvement of large numbers of collaborators, and the use of both northern and southern hemisphere sites, permitting year-round data collection.
		Perspective for the economic impact of particle film technology can be gained from the fact that $185,000,000 were spent in 1997 on insecticides for deciduous tree fruits, nuts, citrus and grapes, and that commodities with a 1999 US farm gate value of $14,300,000,000 are directly impacted by the technology.
		Particle film technology, while still in its infancy, represents a broadly-based insect control system whose impact could be similar to the development of the first synthetic insecticides but without the adverse environment and food-chain characteristics.

	Particle Summary
		These particles do not generally exist as parts of atoms, but are observed in cosmic rays—high-energy radiation that reaches Earth from space—or created in machines called particle accelerators.
		In 1964 the omega-minus particle was discovered with the aid of particle accelerator at the Brookhaven National Laboratory in Upton, New York.
		The particles of the second and third generations are seen in cosmic rays or are produced in particle accelerators.

		Silica particles (for readily soluble salts) and ferrous compounds, which occur in the water as colloids are used to seed crystallization in the water when magnetic treatment is applied.
		The coalescence of particles suspended in the water hinges upon the rate of hydration and the value ofelectrokinetic potential on the surface of particles.
		The coagulation of particles depends immensely on the wetting changes of their hard surface, which are caused by magnetic field.

	Particle removal rates by the mud shrimp Upogebia
		Particle removal rates by the mud shrimp Upogebia pugettensis, its burrow, and a commensal clam: effects on estuarine phytoplankton abundance.
		Particle settlement in the burrow and adhesion to the burrow wall may also be responsible for removal of substantial proportions of phytoplankton.
		Comparison of retention efficiencies of shrimp and oysters indicated that they are both capable of utilizing phytoplankton-sized particles with similar efficiencies and, therefore, may compete for food when phytoplankton abundance is growth-limiting.

	APSnet Feature - Bacteriophage Ecology and Plants
		Phage ecology (e.g., 3) is the study of the interaction of phage with their biotic and abiotic environments.
		Following the traditions of ecology we can differentiate phage ecology into four general categories: (i) Phage organismal ecology is the study of the adaptations that phage employ to increases their likelihood of transmission between hosts such as virion desiccation resistance, ability during infection to repair ultraviolet (UV) light-mediated nucleic-acid damage, and so on.
		Population and organismal ecologies are concerned with the adaptations that organisms employ to enhance their Darwinian fitness over the course of their life cycles.

		In the context of ecology, the question of time-frame must not just be addressed for the present generation but for many more to come, since many of the impacts agricultural practices have on the environment will only begin to appear after hundreds of years.
		The relative combination of soils particle sizes determines a soil’s classification as either a sand, silt, clay or loam soil--a soil defined by a mixture of all three soil particle sizes.
		In the context of farm ecology one must consider that having species with a variety of different characteristics and which fill different niches in the ecosystem increases the overall biodiversity.

		My work on turbulent transport of suspended particles was originally inspired by a paper by Denny and Shibata (1989), which dealt with transport of invertebrate larvae in the marine surf zone.
		At the present time, my principal applied research interests are in the individual- and population-level effects of novel chemical stressors (e.g., antibiotics, nanoparticles) on populations of aquatic and soil organisms, watershed-scale modeling of effects of landcover- and landuse-derived stressors on stream health, and the ecology and control of exotic invasive plants in urban parks.
		My research on the ecology and control of invasive plants involves rigorous, experimentally based assessment of management techniques, as well as empirical and theoretical studies of factors determining the rate of spatial spread of an invading population.

		Ecology as a science is in between very soft sciences like psychology and very hard science like particle physics.

		I have said on several occasions that there is no such thing as the scientific method, a claim that is standard in the philosophy of science.
		The curious reader need only look at whether geologists follow the same approach as biologists to divine this circumstance, or else compare condensed matter physics with particle physics and organismic biology with molecular biology to appreciate that all this method talk bears no resemblance to what actually goes on.
		Given that this is the case, what I want to consider here is why so many people insist - usually in public discourse - that there is such a unified and well defined method, often not hesitating to pour scorn on those who fail to follow its dictates.
