The agrimi (Capra aegagrus cretensis Lydekker), an endangered species of wild goat, was studied on Theodorou Island, Crete, Greece, from May to November 1975 to determine population responses of the agrimi to removals and to document their behavioral patterns. The Theodorou population size was 89 agrimi. A mathematical model of population mortality indicated that the number of animals removed from the island between 1973 and 1975 equalled the expected natural mortality for both sexes. Observations of agrimi showed that they had seasonal and daily activity patterns that minimized their exposure to high ambient temperatures. An age- and sex-specific social dominance hierarchy was found, with old males being most dominant.

The Social

In this study, we investigated the effect of social environment on circadian patterns in activity by group housing either six male or six female mice together in a cage, under regular light–dark cycles. Based on the interactions among the animals, the social dominance rank of individual mice was quantitatively established by calculating Elo ratings. Our results indicated that, during our experiment, the social dominance hierarchy was rapidly established, stable yet complex, often showing more than one dominant mouse and several subordinate mice. Moreover, we found that especially dominant male mice, but not female mice, displayed a significantly higher fraction of their activity during daytime. This resulted in reduced rhythm amplitude in dominant males. After division into separate cages, male mice showed an enhancement of their 24 h rhythm, due to lower daytime activity. Recordings of several physiological parameters showed no evidence for reduced health as a potential consequence of reduced rhythm amplitude. For female mice, transfer to individual housing did not affect their daily activity pattern. We conclude that 24 h rhythms under light–dark cycles are influenced by the social environment in males but not in females, and lead to a decrement in behavioural rhythm amplitude that is larger in dominant mice.

Tarsius Spectrum

Tangkasi (Tarsius spectrum) adalah primata primitif dari Famili Tarsidae dan merupakan primata endemik di Sulawesi. Tangkasi memiliki tubuh kecil, mempunyai mata bulat besar, dapat melompat dan dapat membalik 180˚. Karena keunikan yang dimiliki hewan ini menjadikannya disukai banyak orang sehingga diburu, diperdagangkan secara illegal dan dijadikan sebagai hewan peliharaan. Padahal tangkasi (T. spectrum) dilindungi, termasuk kategori rentan (Vulnerable) dan tercantum dalam CITES Appendix II. Tangkasi yang telah dikandangkan akan mengalami  perubahan perilaku dibanding yang ada di alam. Penelitian aktivitas harian tangkasi yang ada di dalam kandang belum pernah dilakukan di Sulawesi Utara, oleh karena itu, maka penelitian ini perlu dilakukan. Penelitian yang menganalisis aktivitas harian dan tingkah laku tangkasi (T. spectrum) di dalam kandang khususnya dilihat dari aktivitas makan, mencari makan, beristirahat, berpindah, dan aktivitas sosial. Metode pengambilan data secara Instantaneous sampling. Hasil pengamatan terhadap pola aktivitas harian di kandang yaitu : makan (1,5%), mencari makan (8,5%), berpindah (26,8%), instirahat (57,5%), dan sosial (5,5%). Aktivitas tertinggi adalah istirahat, diikuti dengan aktivitas berpindah, kemudian mencari makan, sosial dan yang terendah adalah aktivitas makan.Tangkasi (Tarsius spectrum) is a primitive primate from Family Tarsidae and a  endemic primate in Sulawesi. Tangkasi have a small body, and ayeball, they can jump and their can head flipped until 180˚. Tangkasi already caged will experience a change in behavior campared to the wild. Many  people hunt, trade illegally and use it as pet because of the uniqueness of this species.  Even though tangkasi (T. spectrum) is protected, included in vulnerable category and listed in CITES Appendix II. Research on daily activity of tangkasi in the cage has never been done in North Sulawesi, therefore, this research needs to be done. Studies analyzing daily activities and behavior tangkasi (T. spectrum) in the cage in terms of the activity of eating, foraging, resting, moving, and social activities. Data were collected by using Instantaneous sampling method. The observation of the daily activity patterns in the cage namely: eating (1.5%), foraging (8.5%), moving (26.8%), resting (57.5%), and social (5.5%) . The highest activity is resting, followed by moving activity, foraging, social and respectively the lowest is feeding activity.

Daily Activity Patterns

The seasonal and daily activity patterns of a Saskatchewan population of Crotalus viridus viridis is presented. Snakes emerged from hibernation in late April and migrated into the surrounding river valley and upland regions in early May. Adult migration preceded that of immature age-classes. Several gravid females occupied a rookery near the hibernaculum during the summer months and remained there until parturition. Females did not occupy this site in successive years and may have a biennial or greater reproductive cycle. Snakes returned to the hibernaculum in early September and remained active until early October. The behaviour of snakes in a field enclosure in response to time of day and body temperature (Tb) was recorded during the spring, summer, and fall. Significant differences in the Tb values of sunning, movement, and shading behaviours were noted. Gravid females were significantly more active in all seasons. However, no significant difference in mean Tb was found between males and females in the field, enclosure study, or laboratory thermal gradient. The observed greater level of activity may reflect the high energy demands of gravid females.

Daily Activity Patterns

The purpose of this study was to examine the effects of participation in an aerobic exercise intervention on daily activity occurring outside of the structured exercise sessions. Participants were randomized into one of the following 4 conditions: 1) No-exercise, 2) Low volume, low intensity exercise (LVLI), 3) High volume, low intensity exercise (HVLI), 4) Low volume, high intensity (LVHI). Physical activity was measured over 7 days with an accelerometer at baseline and during week 8 of the intervention. Activity was defined as: sedentary behaviour (SED; < 100 counts/minute), light physical activity (LPA; 100 to 1951 counts/minute), moderate-to-vigorous physical activity (MVPA; ≥1952 counts/minute), and total physical activity (TPA; LPA + MVPA). Activity was quantified as average total minutes per day of each SED, LPA, MVPA, and TPA. A one-way ANOVA was used to determine if time spent in SED, LPA, MVPA, and TPA changed from baseline to week 8. Seventy-one participants (No-exercise; n=12, LVLI n=17, HVLI n=24, LVHI; n=18,) with a mean age of 54 y and waist circumference of 110 cm completed 8 weeks of the intervention. There were no significant differences in SED, LPA, MVPA, or TPA between groups at baseline. There was no significant change in SED, LPA, MVPA, or TPA at week 8 compared to baseline (p>0.05). Similarly, there were no significant differences in activity variables between exercise conditions. Our observations suggest that daily activity patterns do not change with the implementation of an exercise intervention in men and women.
