Describes the natural history of the leopard frog and factors which make it appropriate for short-term study in the classroom. Information on the frog's habits, life cycle, housing, care, and health is included. (DH)

Herein, it is stated that the Secretary of the Interior is directed to transmit to the Senate the report of Dr. Sheldon Jackson upon "The introduction of domestic reindeer in the district of Alaska" for 1900. Following a letter of transmittal from the Secretary of Interior to the President of the Senate, this document presents General…

Extension Services are now reaching out to help the low income farmer. Raising feeder pigs is one way in which the farmer can be helped to boost their standard of living. (MR)

The continuing erosion of financial support for undergraduate laboratories makes cost an increasingly important factor in the choice of undergraduate animal experiments. Projects employing insect predation by rodents, which require minimal equipment and pose a number of interesting questions about animal behavior, are described. (RM)

Describes an approach to teaching animal classification by applying a scientific examination of the types and arrangement of the teeth. This approach may be used by high school students. (HM)

Focuses on the advice and support from science inspectors or advisers with respect to the use of living organisms in schools. Reports that advice, support, and encouragement in the use of living organisms in teaching was widely available at the time of this study and schools have a great deal to lose from the shrinkage in the advisory service.…

This brief statement supports more research on the linguistic and cognitive abilities of animals, particularly primates, and sees direct applicability of such research to language learning by humans with mental retardation who have not learned to speak. (DB)

Describes an inexpensive and easy way to maintain a setup for raising crickets. (ZWH)

Eleven college psychology textbooks were surveyed for their presentation of research using animals characterized by invasive procedures. The methods and procedures of the survey are presented. Survey results are discussed. Results indicated that the majority of studies are presented without reference to the subjective state of the animals…

Investigates children's knowledge about animals by examining the mental models they reveal through their talk when they see animal representations. Presents a study in which representations were provided by robotic models in a museum, preserved animals in a museum, and preserved animals borrowed from a museum and presented in a school setting.…

In Experiment 1, 10 pigeons were exposed to a successive symbolic matching-to-sample procedure in which the sample was generated by the pigeons' own behavior. Each trial began with both response keys illuminated white, one being the "correct" key and the other the "incorrect" key. The pigeons had no way of discriminating which key was correct and…

Increases in regulatory oversight of animal research require verification of effects of standard practices. There are no formal guidelines for establishing free-feeding weights in adult pigeons. In the present study, pigeons were obtained from a commercial supplier, weighed upon arrival, and then held in quarantine for 7 days with free access to…

The present experiment arranged a series of inverted U-shaped feedback functions relating reinforcer rate to response rate to test whether responding was consistent with an optimization account or with a one-to-one relation of response rate to reinforcer rate such as linear system theory's rate equation or Herrnstein's hyperbola. Reinforcer rate…

Identity matching-to-sample has been difficult to demonstrate in rats, but most studies have used visual stimuli. There is evidence that rats can acquire complex forms of olfactory stimulus control, and the present study explored the possibility that identity matching might be facilitated in rats if olfactory stimuli were used. Four rats were…
