A liana is a woody climber that starts at ground level, and uses trees to climb up to the canopy where it spreads from tree to tree to get as much light as possible. Lianas are especially characteristic of tropical moist deciduous forests and rainforests. These climbers often form bridges between the forest canopy, connect the entire forest and provide arboreal animals with paths across the forest. This is a Monkey Ladder vine.

The villi, little finger-like projections all over the intestine, provide increased surface area which allows for rapid digestion.

Food, famine and fungi
Ustilago maydis is a fungus that infects maize crops and causes the disease corn smut. In these images you can see the corn smut fungus (green) infecting a maize leaf (red). This infection will cause large plant ‘tumors’ and can eventually result in plant death.
Diseases like this pose a major threat to modern agriculture and therefore understanding fungal plant pathogens is of huge importance.
BBSRC-funded scientists from The University of Exeter hope to understand the complex interplay between this fungal pathogen and its plant host. This knowledge will then help in the development of novel fungicides that can stop crop infection and keep food on our forks.

The Indian muntjac is also called the “barking deer” due to the barking sound it makes when danger is present.

Brittle stars are closely related to starfish. Their arms can be up to 60 cm (24 in) long, and they have specialized nerves on the ends of each arm that can detect light and the presence of certain chemicals.
