This week's theme was 'change' and the timing was right for members to go out and about and capture the changing scenes.

Oxford Mail:

Quite a few members opted to show colourful leaves after they had fallen from the trees.

Oxford Mail:

According to the Woodland Trust, leaf colour comes from pigments.

Oxford Mail:

These are natural substances produced by leaf cells to help them obtain food. The three pigments that colour leaves are chlorophyll (green), carotenes (yellow) and anthocyanins (reds and pink).

Oxford Mail:

The trust adds: "The depth of colour is influenced by the blend of chemical processes and weather conditions.

"Cold nights: low temperatures destroy chlorophyll so the green leaf fades to yellow, but if temperatures stay above freezing, anthocyanin production is enhanced and the leaves take on a red colour.

Oxford Mail:

"Dry weather: sugars become concentrated in the leaves, more anthocyanin is produced and consequently leaves are redder.

Oxford Mail:

"Bright sunny days: although the production of new chlorophyll stops in autumn, photosynthesis can still occur on sunny autumn days, using the remaining chlorophyll. Sugar concentration increases, more anthocyanin is produced and the leaves are redder."
