Comparisons are made from the variations of invertebrates from polar deserts with these of temperate and subtropical deserts. those areas signify one of the most adverse environments on the earth and an array of recommendations for survival has been built. Polar species are good tailored to chilly and adventure arid stipulations because of low precipitation and shortage of liquid water in the course of the wintry weather.

Some further advances will be necessary to fully capitalize on awake imaging experiments. First, faster laser-scanning is necessary to capture RBC velocity within larger cortical arterioles. Acousto-optic modulators (Lechleiter et al. 2002) can in principle scan vessels with faster flow as well as sample from larger populations of vessels simultaneously. Recent advances in processing of line-scan data using particle image velocimetry will also be useful to assess RBC velocity in larger vessels (Kim and Kim 2011).

1989; Kleinfeld et al. 1998). Conventionally, single line-scans have been used to sample the RBC velocity and diameter of a vessel separately (Schaffer et al. 2006; Shih et al. 2009). However, blood flow is dynamic and could change within the time between each scan. In order to collect more samples simultaneously and with varying trajectories within the imaging plane, we use custom software to direct the imaging laser beam in a user-defined path (Figs. 5c) (Valmianski et al. 2010; Driscoll et al.
