DNA sequencing of male producing Daphnia magna st. P-IT

Global warming has altered the timing of seasons, leading to asynchrony between temperature and photoperiod, as day length is a stable environmental factor not changing with climate. This asynchrony impacts severely cyclical parthenogens, in which photoperiod regulates important seasonal events, such as dormancy and male formation. Understanding the long-term impact of the asynchrony between photoperiod and temperature, as well as the molecular and physiological mechanisms that underpin investment in male offspring is paramount to assess the ability of parthenogenetic species to track climatic change.
