Students from the Old Palace of John Whitgift School from south-west London are carrying out fieldwork for the ecology component of their OCR Biology course at the Medina Valley Centre, in glorious weather. Species diversity was calculated for the animal life in two contrasting ponds, one with brackish water and the other a shaded woodland pond. Species netted included brackish water prawns and damselfly larva, identified using dichotomous keys. Microscopes were used back in the lab to identify the smaller animals including species of daphnia and choronomids.
The students study population interactions on the wonderful Bembridge rocky shore and investigate succession on a developing saltmarsh on the north-east shore line of the Island. Fieldwork for the practical endorsements 3.1, 3.2 and 3.3 will be completed during their residential visit to the Isle of Wight.Back to latest news
