It’s Autumn now!

 

Picture tells the story:

Briefly, leave colour change is caused by the decrease of photosynthesis rate due to the short day time in Autumn. As a result, green pigment (chlorophyll) slowly degraded, and then anthocyanin, carotenoids compounds take place to give leaves reddish, yellowish colour.

I’m back

Safely arrived at Exeter, UK.

Fully recharged. It's time to get on with research & academic, twit/fb/blg lives :)
