Scientists have approached the community of plants and animals that builds in a natural habitat from a novel direction in a new study. Using caves as isolated, extreme habitats for a community, they worked out whether the organism's niche acts as a mechanism to keep the community operating in an ecosystem.

The black soils or 'tera preta' of the Amazon forests were created by burning and composting, in an Pre-Columbian farming style that is still much admired. A study has looked at how these ancient farming techniques may be used to help reduce deforestation.

Yuka, a young mammoth (Mammuthus primigenius), was found preserved in the permafrost of Siberia. Was this mammoth killed by lions or humans and why did the mammoth become extinct? Over 10,000 years later, scientists search for answers.

Modelling and hydrodynamics. If locomotion drove evolution in the same way as it seemed to drive the industrial revolution, ignoring the efficiency of an animal's metabolism, these models of marine animals could almost be the real thing.

In the history of science, sperm chemoattraction has long been recorded in a large variety of species, including plants. When a sperm can find an unfertilised egg more easily, sexual selection and a host of other efficient systems improve.

In extreme conditions or even in normal situations, an animal has to get itself back into the groove quickly after any disorientation. Survival normally depends on it. Your sense of place is dependent on either panorama-matching processes or by matching the actual 3D geometry of a place.
