Circadian temperature compensation
Most chemical reactions change speed with temperature. A plant’s daily clock can keep nearly the same rhythm. How do its components cooperate to do that?
Biological timing
Daily clocks, seasonal signals and the timing of emergence and dormancy.

Problems in this collection
6 problemsInsect photoperiodic timing
Insects use day length to prepare for seasonal dormancy. How do daily clock signals become a seasonal decision?
Mast seeding
Some plants produce huge seed crops together, then little for years. How do weather cues and stored resources set that rhythm?
Periodical cicada timing
A cicada nymph can spend sixteen winters underground before preparing to emerge. What stores that history and opens the developmental gate in the right year?
Hibernation arousal
A hibernating ground squirrel repeatedly warms up in the middle of winter. What internal signal makes a long cold torpor bout end?
Neocalanus diapause termination
A female Neocalanus copepod waits hundreds of metres below the surface, then restarts egg production. What ends its months of dormancy?
