Industry

The natural world is an incredible source of medicines and other valuable resources. 

New uses of natural products are being discovered all the time. Others have been known about and used by indigenous people for hundreds of years.

Scientists at the Museum study organisms, particularly plants, that can be used to provide a range of different products, from vitamin supplements to biofuels, and medicines to flower arrangements. 

The trade in these products can have enormous benefits to local communities in less developed areas of the world. However, they are not always harvested sustainably, and new conservation measures are needed in some areas.

Explore some of the species Museum scientists study below.

  • Amphipleura pellucida
    Amphipleura pellucida - 24/09/2010

    Amphipleura pellucida is a minute photosynthetic organism that can glide across surfaces and is often found suspended in plankton in freshwater lakes. It has a silica cell wall with a highly regular structure that can remain preserved in sediment for centuries. Discover how scientists use this tiny organism’s regular shape to test the magnifying power of microscopes.

  • Azolla filiculoides
    Azolla filiculoides (water fern) - 15/11/2010

    Azolla filiculoides is a tiny invasive fern that has spread around the world, but can be put to good use. It thrives in nutrient-rich ponds and ditches, where it forms potentially damaging thick mats of foliage. Azolla can be a useful fertiliser, thanks to a nitrogen-fixing alga that lives in it, and so is often used in paddy fields to improve rice yields. Take a closer look at this floating fern.

    St Mark’s Fly (Bibio marci) is a large, hairy black fly known for the mating swarms of the males. It is also the model for a fly fishing pattern, known as the hawthorn fly. Find out more about this species.

  • Specifically planted (non-wild) fishtail palm plantation
    Chamaedorea ernesti-augusti (fishtail palm) - 19/01/2010

    The fishtail palm is a favourite accompaniment to floral arrangements. However, it has become endangered due to destruction of the rainforests it grows in and harvesting to meet floricultural industry demands. Find out more about this Central American plant.

  • Desmodesmus subspicatus
    Desmodesmus subspicatus (pond scum, green weed) - 09/10/2010

    Desmodesmus subspicatus is a freshwater green alga that it is found throughout the world. It usually forms flat colonies of cells, but changes to environmental conditions, such as nutrient levels, can trigger it to convert to a unicell form. Find out more about the structure of this microscopic organism and why it is often referred to as a ‘green weed’.

  • Lycopodium clavatum
    Lycopodium clavatum (wolf paw clubmoss) - 10/01/2010

    Lycopodium clavatum resembles some of the earliest plants to live on land. It is used to make Lycopodium powder, which has a range of uses including an explosive used by the film and entertainment industries. Find out more about this plant and the conservation issues it faces.

  • Nitzschia sigmoidea
    Nitzschia sigmoidea - 28/04/2010

    Nitzschia sigmoidea is a large freshwater diatom (microscopic alga) that can be found growing on the surface of mud in ponds and streams. Nitzschia sigmoidea has many uses e.g.  as a metal polish. Find out more about Nitzschia sigmoidea.

  • Plicopurpura pansa
    Plicopurpura pansa - 12/08/2010

    Indigenous people in parts of Central and South America have an unusual way of dyeing cloth - by milking snails. Plicopurpura pansa produces a thick liquid from a gland which turns a rich indigo when exposed to sunlight. Find out how the dye is harvested and why its increasing popularity has an adverse effect on snail populations.

  • Fruits of Solanum lycopersicum
    Solanum lycopersicum (cultivated tomato) - 08/07/2010

    Solanum lycopersicum, the cultivated tomato, originated from South America but is now grown worldwide for its fruits. Recent work by scientists has seen the species classified under the genus Solanum, instead of its previous genus Lycopersicon. Find out more about this species.

  • Solanum melongena, also known as eggplant or aubergine
    Solanum melongena (aubergine) - 15/01/2010

    More commonly known as the aubergine or eggplant, Solanum melongena is used in cooking throughout the world. Learn about the history, the unusual flowering process and the conservation status of Solanum melongena.

  • Solanum sisymbriifolium
    Solanum sisymbriifolium - 23/11/2010

    Solanum sisymbriifolium is a prickly plant with sticky leaves and bright red fruits. It is native to South America, where it grows like a weed. It has been grown in Europe since the 18th century, where it is known as viscid nightshade thanks to the tiny hairs on its leaves and fruits. Discover more about this ‘spiny’ plant, and how farmers use it to control a potato pest.

  • Ananas comosus, fruit
