Insects
Insects play an important role in a biosphere. On Earth they are the animal group with the greatest variety, comprising more than a million species. They live in almost every climate.
On Mars the natural environmental conditions do not allow insects to live, same as for every other known animal. But in an artificial human habitat insects might be very useful to build a biosphere in greenhouses. They can help to pollinate blooms, decay dead pieces of plants, etc. The insect species must be selected carefully to establish a long term stable population.
Spiders may be introduced for insect population control as well as other predatory arthropods such as species of Praying Mantis, but without the benefit of silks.
Certain species can be used as food for colonists, providing valuable proteins.
Wanted species
- Bees and flies for pollinating blooms
- Slaters, springtails and earthworms for accelerating decay in compost heap
Going to put this artcile to good use now.
Open issues
- Is there long term experience with mixed insect populations within a hermetically encapsulated environment?
