Without loss of generality, the variance of independent thermal noise for each link is σ2.
where σ e 2 is the power estimated with the unused PRN code and σ u 2 is the variance of the thermal noise-dependent part of the correlation.
In our system, the three-dimensional (3D) object space is segmented into some distinct discrete sampling cells, and pyroelectric infrared (PIR) sensors are employed to detect the variance of the thermal flux within these cells.
where σ 2 is the variance of the Gaussian thermal noise.
For instance, nesting behavior has been proposed as another potential compensatory response to climate change given that canopy openness affects the daily temperature range (a proxy of thermal variance) and consequently the sex ratios in TSD species [47].
Surprisingly, no study has tested if the effect of thermal variance around high-temperatures (which are particularly relevant given climate change predictions) has the same or opposite effects as around lower temperatures.
Furthermore, a recent study in C. picta showed that increasing the thermal variance around an intermediate temperature had no effect in hatchling morphological, behavioral or immunological phenotypes, nor in embryonic mortality [13] thus, ruling out several potential negative effect of thermal variance at lower temperatures.
In summary, our study underlines the importance of investigating the role of thermal variance to understand TSD sex ratio evolution, its consequences, and its effect on other fitness-relevant phenotypes to understand the response of biodiversity to local and global disturbances at multiple time scales.
The sex-reversing effect of thermal variance observed in our study would superficially suggest that shallow nesting TSD species, such as C. picta, may be more able to respond to climate change than deeper nesting taxa, such as sea turtles [6].
Just a topography of thermal variances, to be assimilated and taken advantage of by the pilgrims.
