Non-instrumented females, for which departure and return dates were recorded (n = 10), had mean trip durations of 18.8 d (range 16 22), mean post-trip mass of 929 g (845 975), and average daily mass gains of 8.7 g⋅d−1 (6.1–13.8.7
Average duration of a trip, in minutes: The base case scenario assumes an average trip duration of 25 minutes.
Over the course of the sardine regime, post-partum females spent increasingly more time attempting to accrue resources [ 25, 26], increasing the mean foraging trip duration by approximately 36% from the late 1970s to the mid to late 1990s (Figs. 3, 4a).
The median trip duration for HSWs traveling abroad was 13 days.
The median trip duration was used to model malaria risk differences assuming longer durations were associated with greater risk.
Of the patients studied, 69.3% were traveling only for tourism, and the median trip duration was <28 days.
However, mean foraging trip durations of about 20 minutes have also been reported during the summer in one study [17], although these bees were also observed to be utilising mass flowering plants (e.g. Rhododendron spp. and Rubus spp).
Total VeDBA was considered as it incorporates the trip duration into the values, whereas mean VeDBA allows comparison of the rate of energy expended across years.
While a high percentage of birds sampled were from pairs (44% in 2011, 74% in 2012, and 72% in 2013), no correlations were found between breeding pairs in foraging behaviour (Pearson correlation: foraging range: r=0.03; distance travelled: r=0.003; trip duration: r=0.02, P>0.05 in all cases) or effort (total VeDBA: r=0.05; mean VeDBA: r=0.4, P>0.05 in all cases).
Finally, comparative analysis of CO2 emissions for different kinds of trips based on trip behavior is conducted using three variables, namely trip distance, trip duration and trip speed.
Trip duration has the most influence on e-bike and battery availability, followed by trip rate, and then trip length.
