Describes the construction and operation of an automatic insect dispenser suitable for feeding small vertebrates that are being maintained for behavioral experiments. The food morsels are squirted from their chambers an an air jet, and may be directed at a particluar portion of the cage or distributed to different areas. (JR)

Water striders are insects that walk and run on the surface of water. Discusses the morphology, physiology, and behavior of these insects. Includes diagrams of stages in the movement of a typical strider. (JN)

Describes a constant-temperature observation chamber and includes instructions on constructing the apparatus. Suggestions for use are given as well as problems that might be encountered. (Author/SA)

Paleoethology seeks to study behavior of ancient animals by building inferential cases of hypothesized behavior patterns. Discusses paleoethological methods and reasons for studying therapsids. Also discusses metabolic rate and possible existence/use of vomeronasal organ to gain insight into the behavior/physiology of these ancient herbivors. (JN)

Discusses the nature of animal communication, including possible relationships between the physical structure of vocalizations and their functions in communicating. Provides tables of mammalian and avian sounds (by species/family) used in hostile and friendly appeasing contexts. (JN)

Discusses various kinds of symbiosis including commensalism, protocooperation, mutualism. Examples are given of each, and emphasis is on the interdependence of living things. (SA)

The great diversity of mating systems found within the insects is described. This description provides an insight into the extraordinary explanatory power of Darwinian selection theory. (JN)

Briefly discusses the view that behavior may be thought of as a phenotypic adaptation that can be quantitatively studied, and then considered in more detail ways in which predatory animals, especially mammals, satisfy their need for food. Topics covered include predatory behavior, hunting modes, prey selection, hunting success, and others. (JN)

Discusses findings that suggest that mating preferences of female mottled sculpins (small North American fish) are influenced by at least four major factors, and that the relative importance of these factors changes through time. The type of choice that a female makes thus depends on time of breeding. (JN)

Presents a description for maintaining adult forms of molluscs and protochordates in order to obtain gametes for laboratory studies of animal development. The methods also include those for culturing embryonic larvae forms in vitro. (Author/SA)

Describes a number of laboratory experiments using woodlice as experimental animals. Includes topics such as physiology of water relations, behavior, and rhythmic activity. (CS)

An experiment was conducted that compared the teaching effectiveness of a computer assisted instructional module and a lecture-discussion. The module, Predator Functional Response (PFR), was developed as part of the SUMIT (Single-concept User-adaptable Microcomputer-based Instructional Technique) project. A class of 30 students was randomly…
