Fig. 2 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 2. Tb of Dorisiana bonaerensis during a light rain under a heavy overcast on the 21st December 1986. These animals were not exposed to direct solar radiation before the Tb was recorded. Closed circles, represent body temperatures of singing D. bonaerensis; open circles, represent body temperatures of D. bonaerensis engaged in other activities (including no activity). Details as in Fig. 1.
Fig. 3 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 3. Distribution of Dorisiana bonaerensis Tb as a function of Ta. The slope of the linear regression for "active" animals (closed circles) is significantly different from one, suggesting thermoregulation. The slope of the linear regression for "inactive" animals (open circles) is not significantly different from one, suggesting no thermoregulation is occurring.
Fig. 4 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 4. Distribution of Tb of as a function of Ta when Dorisiana bonaerensis were not exposed to solar radiation. The slope of the linear regression for " active " animals (closed circles) is significantly different from one, suggesting thermoregulation is occurring with endogenous heat. The slope of the linear regression for " inactive " animals (open circles) is not significantly different from one, suggesting no thermoregulation is occurring when the animals do not generate heat for activity.
Fig. 1 in Diurnal activity, temperature responses and endothermy in three South American cicadas (Homoptera: Cicadidae: Dorisiana bonaerensis, Quesada gigas and Fidicina mannifera)
Fig. 1. Diurnal distribution of Tb of Dorisiana bonaerensis and Quesada gigas on the 13th December 1986. A rainstorm from 07.00 to 08.00 h followed by a misting rain until 09.45 h delayed the start of activity approx. 2 h. Body temperatures are below ambient temperature before activity begins. Body temperatures are elevated at the start of activity (10.00 h) and regulated throughout the day. Body temperatures of quiescent animals decrease with ambient temperature after sunset (20.10 h). Animals participating in the evening chorus have body temperatures in or near the body temperature range measured during the day. Closed circles, Tb of singing D. bonaerensis; open circles, Tb of D. bonaerensis engaged in other activities (including no activity); closed triangles, Tb of singing Q. gigas; open triangles, Tb of Q. gigas performing other activities; solid line, ambient air temperature.
Top view of DR1/DR2 double riffle, each section contains a spawning ground made up of eight gravel-filled trays, a rest area. The "double riffle" was designed to accommodate two groups from 25 to 50 specimens of broodstock in strictly identical conditions. The spawning grounds are equipped with waterproof, motion-sensing cameras with infrared night vision, connected to a 1000 Gb recorder. The diurnal and nocturnal activities of the two groups can therefore be simultaneously recorded over a long period. in Reproduction of Zingel asper (Linnaeus, 1758) in controlled conditions: an assessment of the experiences realized since 2005 at the Besançon Natural History Museum

Figure 2 in Diurnal time-activity budget and foraging techniques of red-crested pochards (Netta rufina) wintering at the wetlands of West Bengal, India
Figure 2. Canonical correspondence analysis (CCA with 95% ellipses) ordination diagram showing the scatter plot for the month-wise and site-wise density of the wintering RCPs together with the selected environmental variables. Vector lines represent the relationship of significant environmental variables to the ordination axes; their length is proportional to their relative significance.

Data from: Effects of the colour of photophase light on locomotor activity in a nocturnal and a diurnal South African rodent
Many physiological and behavioural responses to varying qualities of light, particularly during the night (scotophase) have been well documented in rodents. We used varying wavelengths of daytime (photophase) lighting to assess daily responses in locomotor activity in the nocturnal Namaqua rock mouse (Micaelamys namaquensis) and diurnal four-striped field mouse (Rhabdomys pumilio). Animals were exposed to three light-dark cycle regimes: a short-wavelength- (SWLC), a medium-wavelength- (MWLC) and a long-wavelength light-dark cycle (LWLC). Overall, daily locomotor activity of both species changed according to different wavelengths of light, the diurnal species displayed most activity under SWLC and the nocturnal species exhibited the highest levels of activity under LWLC. Both species showed an increase in diurnal activity and a decrease in nocturnal activity under LWLC. These results indicate an attenuated responsiveness to long wavelength light in the nocturnal species, but this does not appear to be true for the diurnal species. These results emphasize that the effect of light on the locomotor activity of animals depends on both the properties of the light and the temporal organization of activity of a species.

Data from: Diurnal variation of brain activity in the human suprachiasmatic nucleus
<p>The suprachiasmatic nucleus (SCN) is the central clock for circadian rhythms. Animal studies have revealed daily rhythms in the neuronal activity in the SCN. However, the circadian activity of the human SCN has remained elusive. In this study, to reveal the diurnal variation of the SCN activity in humans, the SCN was localized, and its activity was investigated using perfusion imaging. We scanned each participant four times a day, every six hours, and higher activity was observed at noon while lower activity was recorded in the early morning. The SCN activity was then measured every thirty minutes for six hours from midnight to dawn and showed a decreasing trend and was comparable with the rodent SCN activity after switching off the lights. These results suggest that the diurnal variation of the human SCN follows the zeitgeber cycles of mammals and is modulated by physical lights rather than the local time.</p>
