Key words: corticosterone, stress, behavior, ethogram, avian, psittacine, cockatiel, Nymphicus hollandicus
Baseline corticosterone samples were obtained at 9:00 am on a separate day to the ethogram, within 3 minutes of entering the aviary room, to minimize the effects of daily photoperiod variation on the corticosterone levels.
The activity is done over two 3-hour laboratory sessions to allow enough time for the students to (1) engage in class discussion of key concepts in behavioral observations, (2) become familiar with the CamClickr project, (3) generate testable hypotheses, and (4) collect observations from CamClickr and create and use ethograms.
* use ethograms to construct and test hypotheses about the evolution of behavior
of body patterning behavior in the squid Loligo vulgaris reynaudii on spawning grounds in South Africa.
The sampling protocol proposed here should be used in future studies dealing with behavioral repertoires and ethograms
because it minimizes the problems of pseudoreplication and provides a more realistic view of the allocation of time and energy for different activities.
of two captive mother-calf dyads of bottlenose dolphins (Tursiops truncates): Comparison with field ethograms
Precopulatory male ethograms
of three species of Lycosa Latreille 1804 (Araneae: Lycosidae) of the Iberian peninsula.
fasciata, Navanax inermis, and Bursatella leachii) have similar behavioral descriptions or ethograms
(Kupfermann and Carew, 1974; Susswein et al., 1984; Leonard and Lukowiak, 1984, 1986; Ramos et al., 1995).
Degree of postoperative pain was assessed for the first 4 days after surgery by use of 3 methods: an electronic perch for assessment of weight-bearing load differential of the pelvic limbs, 4 pain scales, and analysis of video-recorded partial ethograms
for bird activity and posture.
It is therefore useful to compare the ethograms
of these two Loligo species with that of S.
Can body patterning ethograms
help distinguish subspecies?
