Eliminative Behavior of captive numbats myrmecobius fasciatus mammalia marsupialia pattern and identification of fecal deposits
Zoo Biology, 2013Co-Authors: Lindsay A Hogan, A Lisle, S D JohnstonAbstract:This study examined the spatial defecation patterns of numbats within captivity and tested the efficacy of a food colorant as a fecal marker in this species. Rather than randomly distributing scats throughout their environment, the numbats aggregated their feces at specific sites forming latrines. It is unclear whether the strong inclination for latrine formation was due to this species' inherent Behavior or is a direct result of captivity. Males were found to have a higher daily defecation rate, different defecation time, larger number of latrines, and greater number of scats per quadrant, as compared to females. In this study, the majority of scats were deposited along enclosure boundaries and for both sexes there was a higher probability of latrines being placed along enclosure fencing shared with a female neighbor. The high concentration of latrines along boundaries suggests that they may play a role in territorial defense. The results also indicated that captive numbats tend to choose defecation points away from food and refuge sites. Transit and total retention time of the marker through the GIT was ≤3hr and between 24 and 27hr, respectively. A marker dose of 3gtts feed-1×2 feeds day-1 was required to reach a steady and detectable state of marker output, which enabled accurate identification of individual samples during the breeding season. Reliable labeling was obtained using blue and red colored food dye, and there was no evidence that incorporation of the marker into the diet had any negative effects on food intake.

Vomiting Behavior of the Spinner Dolphin (Stenella longirostris) and Squid Meals
Aquatic Mammals, 2004Co-Authors: José Martins, Lizete Jardim Pandolfo, Ivan SazimaAbstract:We describe and illustrate the vomiting Behavior of the spinner dolphin (Stenella longirostris), an Eliminative Behavior poorly known for cetaceans in the wild. The vomiting may be conveniently described in six Behavioral phases: opening beak, closing beak (water intake), swallowing water, pausing, opening beak about to void, and voiding offal and water. Spinners vomit after a meal rich in squids, and, therefore, we relate this Eliminative Behavior to the presumably irritating remains of this meal type (squid beaks). The vomits are a rich and predictable food source for plankton-eating reef fishes.
