Recently, marine ecologists and economists have made the world aware of some alarming news about the ocean's bounty. According to researchers, populations of edible sea life are falling worldwide, and if the pattern were to continue, we would have no ocean fish left to harvest by midcentury. However, critics believe that this projection relies on…

The present study investigated whether Pavlovian conditioning contributes, in the form of the response operandum serving as a conditioned stimulus, to the increase in the rate of response for 1% liquid-sucrose reinforcement when food-pellet reinforcement is upcoming. Rats were exposed to conditions in which sign tracking for 1% sucrose was…

The concept of plasticity describes the mechanisms that rearrange cerebral organization following a brain injury. During the last century, plasticity has been mainly investigated in humans with acute strokes. It was then shown: (i) that the brain is organized into highly specialized functional areas, often designated "eloquent" areas and (ii) that…

Presented is an annotated bibliography of reference materials on the maintenance of plants and animals. (SL)

The 2001 Foot and Mouth Disease (FMD) epidemic effectively closed large parts of the UK countryside for several months. Local firms found their operations disrupted and suffered losses of trade. The individual and collective experiences of affected firms provide vivid insights into how rural businesses and the local economies they constitute…

Described a project in which students raised goats to help provide a variety of animals to people around the world who were trying to increase quantity and improve strains of livestock. (Author/RK)

This experiment assessed the effects of "d"-Amphetamine and ethanol on reinforced variable and repetitive key-peck sequences in pigeons. Pigeons responded on two keys under a multiple schedule of Repeat and Vary components. In the Repeat component, completion of a target sequence of right, right, left, left resulted in food. In the Vary component,…

Daily administration of cocaine often results in the development of tolerance to its effects on responding maintained by fixed-ratio schedules. Such effects have been observed to be greater when the ratio value is small, whereas less or no tolerance has been observed at large ratio values. Similar schedule-parameter-dependent tolerance, however,…
