Ecologists find new clues on climate change in 150-year-old pressed plants
Date:9/21/2010

Plants picked up to 150 years ago by Victorian collectors and held by the million in herbarium collections across the world could become a powerful and much needed new source of data for studying climate change, according to research published this week in the British Ecological Society's Journal of Ecology.

The scarcity of reliable long-term data on phenology the study of natural climate-driven events such as the timing of trees coming into leaf or plants flowering each spring has hindered scientists' understanding of how species respond to climate change.

But new research by a team of ecologists from the University of East Anglia (UEA), the University of Kent, the University of Sussex and the Royal Botanic Gardens, Kew shows that plants pressed up to 150 years ago tell the same story about warmer springs resulting in earlier flowering as field-based observations of flowering made much more recently.

The team examined 77 specimens of the early spider orchid (Ophrys sphegodes) collected between 1848 and 1958 and held at the Royal Botanic Gardens, Kew and the Natural History Museum in London. Because each specimen contains details of when and where it was picked, the researchers were able to match this with Meteorological Office records to examine how mean spring temperatures affected the orchids' flowering.

They then compared these data with field observations of peak flowering of the same orchid species in the Castle Hill National Nature Reserve, East Sussex from 1975 to 2006, and found that the response of flowering time to temperature was identical both in herbarium specimens and field data. In both the pressed plants and the field observations, the orchid flowered 6 days earlier for every 1oC rise in mean spring temperature.

The results are first direct proof that pressed plants in herbarium collections can be used to study relationships between phenology and climate change when field-based dat
