He explains that «we are the first to show these similarities between gene activation
in diapause and aging in vertebrates.

In aging, this gene expression presumably occurs to compensate for the accumulation of protein damages; during
diapause, the same genes may be activated to prepare the whole embryo to catch up with the interrupted development and be ready to hatch as the rainy season starts.
Ironically, he found his work circling back to
diapause, the subject of his master's thesis, when
in 2001, his lab showed that dwarf fruit flies with defective insulin - like receptors live longer.
Tatar's research, along with simultaneous independent work by Linda Partridge of University College London, U.K., and her colleagues, demonstrated that an insulin - like signaling pathway controls
diapause and aging
in flies — similar to what had already been found
in the roundworm Caenorhabiditis elegans (see «Growing Old Together»).

In the springtime the grass is green, lupines are growing, and the hungry caterpillar awakes from
diapause.

in other periods
Bowhead whales are assumed to feed on pelagic and epibenthic zooplankton
in late summer and fall (Finley 2001; Lowry et al. 2004; Pomerleau et al. 2011b), and on pre-ascending
