We may have underestimated the impact of shifting seasons on species and ecosystems, according to New Zealand researchers. Seasonal changes in snow cover, temperature and rainfall have shaped the life cycles and behaviour of most species, but in the face of unprecedented changes to Earth’s natural rhythms due to climate change, these adaptations may become out of sync. The knock on effects throughout food-webs, ecosystems and human society could be significant, for example a mismatch between phytoplankton blooms and the life cycles of fish could affect the health of fisheries.
