8 images of some flowerheads such as roses and water lilies whose outer petals are longer than the petals in the centre of the flower

3 images of some asymmetrical flowerheads such as an iris and an Orchis Sima or Monkey Orchid

7 images of some symmetrical flowerheads such as asters and sunflowers whose petals radiate from the centre of the flower

How do different populations adapt to their environment? Let’s explore this concept through guppy speciation.

Scientists can observe birds to get useful information about the health of, and changes in, an ecosystem.

Aquaculture is seen as a sustainable way to produce fish. But are farmed salmon better than wild fish?

When fertilizers from agriculture get into lakes and rivers, big problems can result for aquatic ecosystems, food chains & webs!
