Virtually all ecosystems are seasonal, and seasonality patterns are projected to change - but we lack an understanding of how such changes will affect populations. One example are arid ecosystems where rain is becoming increasingly scarce while temperatures are on the rise, with both environmental drivers showing highly seasonal patterns. Another example can be drawn from temperate, high-altitude systems, where changes in seasonal snowfall regimes may fundamentally affect hibernating species. Using the Kalahari meerkats (Suricata suricatta) and yellow-bellied marmots (Marmota flaviventris), I am investigating the effects of seasonal changes in interactive environmental drivers on the structure and viability of natural populations.
