	Perverse incentive - Wikipedia, the free encyclopedia
		A perverse incentive is a term for an incentive that has the opposite effect of that intended.
		This effect is called the 'Welfare trap.' In some cases, this incentive is countered by gradually phasing out benefits (for example, reducing benefits by 50 cents for each dollar earned), thus preserving the incentive to seek even part-time work.
		Paying the executives of corporations proportionately to the size of their corporation is intended to encourage them to grow their companies by growing the bottom line (and not their earnings per share).

	Unintended consequence - Wikipedia, the free encyclopedia
		As with other unintended consequences, these side effects are often negative, but some are beneficial—for instance, aspirin, a pain reliever, can also thin the blood and help to prevent heart attacks.
		The introduction of rabbits into Australia for sport led to an explosive growth in the rabbit population; rabbits became a major feral pest in Australia.
		One possible reason for the effect is that the enactment of gun control laws leave citizens vulnerable to criminals who do not respect the prohibitions on gun ownership, thereby making crime a much safer occupation.

	Intro to Contraception (Site not responding. Last check: 2007-10-31)
		While rodents are the favorite "tool" of biomedical researchers, other species have not been completely ignored: chimpanzees, chinchillas, bears, squirrels, horseshoe crabs, pigeons, opossums, elephants, and more have all been the subject of experimentation.
		For example, the presence of cats on certain islands is seen as a threat to native species and attempts have been made to exterminate or at the very least to reduce their numbers.
		The loss of different species, often caused by the destruction of their habitat -- or in the case of the flfooted ferret by the deliberate (but unthinking?) destruction of that species' primary food source -- is lamented by environmentalists and has at times caused a political uproar in the United States.

		The primary threats to the species are the effects of fire suppression, and shading and competition from native and alien plants.
		The species is found from 200 to 445 m (656 to 1,460 ft) in elevation, primarily on thin soils composed of chert and shale (Amme and Havlik 1987a).
		The primary threats to Arctostaphylos pallida are the effects of fire suppression, and shading and competition from native and alien plants.

	Introduction to Permaculture
		They are swapping plants and mapping species of trees in the bush which are good bearers of nuts, and operating a seed exchange, that sort of thing.
		The effects of this on world climate are becoming apparent both in the composition of the atmosphere and in the inability of the atmosphere to buffer changes.
		So really what's happening in the world climate is not that it is tending toward the greenhouse effect; it is not that it is tending toward the ice age; it is starting now to fluctuate so wildly that it is totally unpredictable as to which heat barrier you will crack.

	alien species
		Some species that are successful are sometimes able to adapt to the local conditions and find a comfortable, limited niche in their new home without aggressively disrupting local biological communities or causing significant problems.
		The ecological effects of their initial arrival are largely unknown, because knowledge about the biological communities at the time is scarce.
		Once an invading species becomes established in a new, congenial home it is a costly and usually losing battle to be rid of it.

	SCOPE 49 - Methods to Assess Adverse Effects of Pesticides on Non-target Organisms, Chapter 15, Methods to Evaluate ...
		In 1987, the pesticide manufacturing industry noted that approximately 40 species of arthropods had developed resistance that caused serious practical difficulty for their control in many areas (Table 15.1).
		Mutagenicity is an individual consequence of exposure to certain pesticides, but it may or may not result in heritable change; resistance is a consequence of the selection of a rare allele in a population group, and it may or may not be due to an induced mutation.
		Genetic engineering of resistance in beneficial species of insects, or even in domestic animals, may be the logical extension of accomplishments with crops when adequate cloning vectors are identified.

		Researchers have isolated and identified several species from natural waters that have proven to be nutritious food for growing some commercially important bivalves.
		For example, if several algal species are cultured in one room, a compromise in environmental conditions may be necessary.
		A mixture of several algal species is frequently used to enhance growth.

	Indiana Aquatic Nuisance Species (ANS) Management Plan
		An "invasive species" is defined as a species that is nonnative (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health (Executive Order 13112; http://www.invasivespecies.gov).
		The introduction of nonindigenous aquatic nuisance species into the Great Lakes, Mississippi River, and inland state waters is a source of biological pollution that threatens not only the ecology of the region and states' water resources, but also the economic, societal and public health conditions of the region and states.
		Exotic species that have a negative impact on other types of commercial facilities or animals that affect recreational uses of water, such as clogging of intake pipes by zebra mussels, are not directly defined or regulated as pests in state law.

	EXOTIC SPECIES LEGISLATION
		Some species will pose such immediate ecological and economic harm that they must be addressed immediately (e.g., the zebra mussel), while other species that have been established for hundreds of years may be non-threatening and therefore warrant only a low ranking on the priority list.
		The negative side effects are so numerous that bio control should only be employed when the party seeking to use it demonstrates that a) this method is the most effective means of con trolling another non-native species and b) this method will not be likely to have a significant impact on the ecosystem.
		In prioritizing these species, ESS should consider whether the species is threatening a wilderness area, an island, an area of rich biodiversity, or the habitat of an endangered species, as well as the economic damage it causes.

	Species-dependent effects of zooplankton on planktonic ecosystem processes in Castle Lake, California Ecology - Find ...
		These direct effects can in turn result in a myriad of indirect effects, which can dramatically alter the structure and dynamics of ecosystems, often in unforeseen ways (Paine 1992).
		Much of the past research on species differences in grazing effects, particularly the stream research, has emphasized the importance of feeding behavior and morphology in ultimately explaining subsequent interspecies differences.
		To contribute to the understanding of zooplankton species impacts on planktonic ecosystems, we used Diacyclops bicuspidatus thomasi, Daphnia rosea, Diaptomus novamexicanus, and Holopedium gibberum, the four most common crustacean zooplankton in Castle Lake, California.

	Scott Johnson: The Counterpoint Of Species, 1997 - Introduction
		Hybridism has received a very bad press during the second half of the 20th century, but the patchwork logic of human culture is echoed by the very physical structure of our brains, in which jury-rigged modules are added to each other simply because they work, not because they are elegant or logical.
		The inertia of this attitude is considerable, and even now the sometimes gleefully messy melting pot of the avant gard community is not immune to occasional fussy fits of house-cleaning, as the heirs of a previous generation's rebellions attempt to fortify the ground gained by their heroes.
		High Modernism may have gotten itself into trouble by thinking that progress and specialization are synonymous, but both modernism and classicism have shared another misreading of Darwinian principles; one which has also been used to provide a background justification for the separation of post-classical music from its surrounding culture.

	INTRODUCTION
		He concluded, "Due to the lack of existing aquatic species information, especially with regard to mussels, we recommend that all areas of potential impact be surveyed for endangered species." In addition, the memo listed three endangered mussel species which were known to occur in the nearby Chippewa River and might occur in the Flambeau River.
		If their species identification proved to be accurate, the DNR concluded "It (Flambeau River near the mine) would be considered an unusually diverse dragonfly community which include several species rare or uncommon in the state."(67) One of these species, the pygmy snaketail dragonfly, is a state-listed endangered species.
		As such, it should reduce or eliminate the effects of T ferrooxidans except in portions of the MWDF where the tailings are exposed to the atmosphere." (97) In this instance, it appears that some of the DNR's reasons for predicting a low potential of acid development was based upon this assumption.
