Spatiotemporal variability in activity patterns of urban street cattle as function of environmental factors.

Spatiotemporal variability in activity patterns of urban street cattle as function of environmental factors. Chronobiol Int. 2019 Aug 01;:1-11 Authors: Sahu BK, Parganiha A, Pati AK Abstract In the current study, we studied behavioral patterns, such as foraging, activity, standing, and laying in a population of cattle wandering on streets of Raipur city. We also determined the effects of four environmental factors (temperature, humidity, light, and noise intensities) on these behaviors. We recorded all four behavioral variables at four time points each day over a period of three consecutive days at 10 randomly selected locations using on-site human observation method, digital video, and still camera. We used Cosinor rhythmometry to analyze the time series data on all four behavioral variables. One-way ANOVA was performed to determine the impact of the factor "time of the day" on all observed behavioral variables. Pearson correlation was also employed to evaluate the relationship between the environmental and behavioral variables. Cosinor analyses revealed statistically significant 24-h rhythms in all observed behavioral variables, at the group level, with peaks of foraging, activity, standing, and laying located at 11.54 h, 14.54 h, 18.66 h, and 23.88 h, respectively. Factor "time of the day" had statistically significant effect on all observed behavioral variables. Foraging and activity were found to be positively correlated wit...
