Diurnal activity patterns of coypu in an urban habitat

It is generally admitted that in coastal areas, herons of the genus Ardea adjust their foraging time according to the tidal cycle. However, to what extent do tides control the herons' daily rhythm of activity? To answer this question, we present the day and night activity patterns of Great Blue Herons (Ardea herodias) arriving to feed their young at a heronry located in a nontidal environment in southern Quebec. Herons were about half as active at night as during the day. Therefore, although significantly less than diurnal activity, nocturnal activity was not negligible, and consequently the tide cycle is not the only factor controlling the daily rhythm of the herons' activity. Those breeding pairs that were most active during the day were no more or less active at night. Diurnal activity was more closely correlated with the number of young that fledged than was nocturnal activity. Thus, night activity was not necessarily important for the survival of young herons, but it could be explained by other factors such as the greater availability of certain prey at night.

Walia ibex (Capra walie) is an endangered and endemic species restricted to Simien Mountains National Park (SMNP), Ethiopia. Data on activity patterns of walia ibex were collected during October 2009 to November 2011, and the main objective of the research was to determine diurnal activity patterns of walia ibex in Simien Mountains National Park in order to design sound conservation strategies for the species. Scan sampling method was used for data collection on diurnal activity patterns of walia ibex. Diurnal activity patterns in walia ibex were bimodal, in which they were active before and after noon. They rest in shade on rocks and cliffs during the mid-day to protect themselves from hot sun and predators. Activity patterns of walia ibex during the day showed statistically significant differences (F7,18228= 82.09, df=7, p<0.01). Feeding showed significant differences compared to moving, standing, resting, socializing, and other activities (p<0.05). Diurnal activity records in the walia ibex population during the wet and the dry seasons showed that time spent feeding was the highest and vigilance was the lowest. Knowledge of the pattern of this behavior can especially be useful to design conservation planning as successful reproduction in the population may be threatened by anthropogenic disturbances. Thus, information about the diurnal activity patterns of walia ibex is essential for conservation planning of the endemic and endangered walia ibex in its natural habitats.

Time Specific

2016 has been an exciting year for research in physical activity, inactivity and health. Recognition of the importance of all physical behaviors (physical activity, sedentary time and sleep) across the 24-hr day continues to grow. Notable advances have included: applications of recent methodological innovations that account for the codependence of the behaviors in the finite 24-hr period showing that the balance of these behaviors is associated with health; methodological innovations focusing on the classification of behaviors and/or quantification of the 24-hr diurnal activity pattern; and a series of systematic reviews that helped provide the evidence base for the release of the innovative 24-hr movement guidelines earlier this year. This commentary focuses on just two of these papers: the first by Goldsmith and colleagues who demonstrate a new statistical method that exploits the time series nature of accelerometer data facilitating new insights into time-specific determinants of children’s activity patterns and associations with health; the second by Tremblay and colleagues who describe the evidence base for associations between each physical behavior and children’s health, the emerging evidence base for associations between the balance of behaviors and health, and development of the world’s first 24-hr movement guidelines.
