Resource exploitation

Choice tests are the most commonly used method to evaluate food acceptance and preferences (see section 7.3.3). Flavors can be added to a readily accepted carrier or base food to control for consequences, or odor stimuli can be placed adjacent to a desirable resource. Flavors that reduce intake relative to a baseline are defined as aversive, while those that increase intake are taken to show a preference. 

Mountain beaver do not adapt well to food deprivation, but they can be trained to respond to a preferred food (e.g., apple). Therefore, mountain beaver can be accustomed to a feeding schedule that includes apples and then this highly preferred food is treated with stimuli or placed adjacent to test odors during test trials (Epple et al. 1993, 1995 Nolte et al. 1995a, 1995b). 

One measure of the attractiveness of scents to carnivores is the number of approaches to a scent station. Typically, a scent station is a scented stake surrounded by a raked patch of dirt. Bullard et al. (1983) placed scent stations near known coyote locations to assess relative efficacy of materials for use as attractions. Approaches to the scents were then calculated by counting the number of tracks and deposited scent mounds (scats) in the raked area after a specified interval. 

The paradigm to condition animals to avoid flavors is described in section 7.3.4. Basically the hedonic value of a flavor paired with negative gastrointestinal consequences declines, while a flavor s hedonic value increases if associated with positive consequences. Numerous studies with a variety of species have been conducted and are described elsewhere (see reviews by Barker et al. 1977 Zahorik 1977, Zahorik and Houpt 1981 Braveman Bronstein 1985 Provenza Balph 1988, 1990 Provenza 1995). 

Moulton (1977) used operant conditioning to determine the minimum detectable thresholds of dogs for several odors. Dogs were first trained to insert their noses into an airstream to obtain water as positive reinforcement. Next, odorant was added to the airstream as a response contingency, that is reinforcement was presented only in the presence of the odor. Incorrect responses were punished with time-outs (i.e., the test was interrupted for a period of time). Stimuli concentrations were successively lowered until the subject s performance dropped to a level of chance.

In some parts of the world the need to exploit natural resources is so urgent that it has preceded the formulation of adequate environmental controls. The pace of natural resource exploitation and the growth of associated industries have overtaken the evolution of institutions, which would have the authority to exert such controls. 

Water scarcity is defined as a situation where insufficient water resources are available to satisfy long-term average requirements. It refers to long-term water imbalances, where the availability is low compared to the demand for water, and means that water demand exceeds the water resources exploitable under sustainable conditions.

Water scarcity is a structural, persistent drought affecting resources and aquatic ecosystems, with implications in water quality and societal needs. Scarcity results in repeated drought episodes. While drought is a temporary (and often normally associated to climatic patterns) decrease in water resources, water scarcity occurs when water demand exceeds the water resources exploitable under sustainable conditions.

The aggregation pheromones of insects can be classified into two groups those emitted by males or females to attract both sexes simultaneously for resource exploitation and/or mating (e.g., bark beetles Byers, 1989) and those emitted to attract and arrest individuals of specific developmental stages, as found in the German cockroach Blattella germanica (Ishii and Kuwahara, 1967,1968 Sakuma and Fukami, 1990, 1993).

The Protocol on Environmental Protection to the Antarctic Treaty designates Antarctica as a natural reserve, devoted to peace and science and provides for an indefinite ban on mineral resources exploitation and on mineral prospecting. This ban, and indeed all parts of the Protocol, can be renewed after 50 years from the entry into force of the Protocol at the request of any Consultative Party. 

Figure 19.2. Resource exploitation in automated laboratories The different resources (gray boxes) can be used by either automated systems (yellow area) or laboratory personnel (blue area).The process of laboratory work-procedures can be managed by the means of computer technology (information logistics) as well as automation technology (sample logistics).

In view of mans inability to adapt to major environmental changes, pollution is equated with disturbance of ecological balance and loss of stability. Increasing the chemical diversity (number of components and phases) makes an equilibrium system more resistant toward external influences imposed on the system. In an ecosystem, its members are interlocked by various feedback loops (homeostasis) and thus adapted to coexistence for mutual advantage increased diversity makes the system less subject to perturbations and enhances its survival. Because various kinds of disturbance cause similar patterns of change in aquatic ecosystems and affect their stability in a predictable way, general measures of pollution control beyond those of waste treatment can be outlined which mitigate the conflict between resource exploitation and protection of natural waters.

Gregarious behavior might have various advantages ranging from resource exploitation to mate finding or reproductive synchronization. For example in some terrestrial isopods, reproductive activity of females appears to be synchronized through chemical cues transmitted via feces (Mead and Gabouriaut 1988 Caubet et al. 1998), which are common in communal shelters. 

It should be pointed out that legitimacy issue must be paid attention to optimization deployment of coal resources because reconfiguration of coal resources is involved in optimization deployed model. That is, the currently relevant laws and regulations must be strictly carried out about mineral resources exploitation in the course of implementing resources optimization deployed model in China. 

The safety problem, which includes production safety in the remaining resource exploitation and the living safety of workers and residents, is extraordinary remarkable during resource exhaustion and must be given enough attention.

Wood is one of the oldest renewable resources exploited by human activity in the form of timber, tools, source of energy and of shelter. Wood is a complex natural material whose stmcture represents the very paradigm of a composite assembly, as briefly outlined in Chapter 1, together with general references to the traditional uses of this multifarious vegetable manifestation. Its main components (see Chapter 1) are cellulose (A), hemicelluloses (B) and lignin (C), accompanied by minor contributions of low molecular weight compounds and mineral salts. This book includes several chapters devoted to the utilization of both the major and some of the minor components of wood considered individually as a source of polymers.
