The aims of this project were to characterize tiger salamander (Ambystoma tigrinum) spermatozoa motility over time, when excreted as either milt or spermic urine prior to packaging into a spermatophore, and to determine the effect of temperature on sperm motility. A split-plot design was utilized to assess the motility of the two pre-spermatophore sample types at two temperatures, 0°C and 20°C (n = 10 for each treatment). Spermiation was induced through exogenous hormone treatment of luteinizing hormone releasing hormone analog in order to collect both milt and spermic urine, which were evaluated for motility, divided into two separate aliquots, and subsequently stored in either an ice-bath (0°C) or on the benchtop (20°C). The decay rate of sperm motility was assessed by reevaluating subsamples at 0.5, 1, 2, 3, 5, 7, and 24 hours following the initial assessment. Results showed that sperm stored at 0°C had significantly higher progressive, non-progressive, and total motility for both sperm collection types over time. An interaction was found between collection type and time, with milt exhibiting lower initial motility that was more sustainable over time, compared to spermic urine. For both milt and spermic urine, motility decreased rapidly with storage duration, indicating samples should be used as soon as possible to maximize motility for in-vitro fertilization and cryopreservation. This is the first study to describe the differences in sperm motility between milt and spermic urine from an internally fertilizing caudate and demonstrates the benefits of near freezing temperatures on sperm longevity.

The experiment was designed to demonstrate that a stimulus presented contiguously with the onset of a positive reinforcer, food, may serve as a conditioned elicitor of approach behavior. 20 naive male rats were assigned to two groups. Experimental Ss received their entire daily food supply paired with a flashing light. For control Ss, the light was presented uncorrelated with feeding. Approach behavior was assessed in a shuttle box. When the light was presented on the side of the hurdle opposite S, experimental Ss crossed the hurdle and approached the light significantly faster than did control Ss. The results are taken as physical representation of the conditioned approach responses postulated in Denny's interpretation of positive reinforcement effects.
