The soils of different agrosystems are studied simultaneously with termite activity in the context of long-term restoration project. The aim is to highlight the positive impact of termites on soil physicochemical properties. Previous studies have mainly focused on permanent structures built by those insects such as mounds, punctually impacting the landscape. In order to study a more widespread impact of termites, the temporary structures built for food foraging are compared to the underlying soil. It is assumed that, after rainfall or watering, these structures will return to the soil surface. The three sites are a fallow land (permanent pasture), a tilled field and agroecological raised beds. Termites only show up where there is organic matter, irrespective of its type. In the three sites, clay content, available K, Mg and P, organic carbon, pH, cation exchange capacity (except in the fallow) and exchangeable bases are increased in the biogenic constructions. The increase is generally lower in the beds because the reference soil already has higher values. In the field and the fallow, the aggregation is improved in termite sheetings, as the macroaggregates in both sites and the protected microaggregates in the field increase whereas the free microaggregates decrease. In the beds, the reference soil already has a better physical stability, with more macroaggregates and protected microaggregates. Our results demonstrate that agricultural conservation practices are able to improve most of the soil properties in the same way that for ecosystem engineers such as termites.

This pioneering book looks at the importance of insects to culture. While in the developed West a good deal of time and money may be spent trying to exterminate insects, in other cultures human-insect relations can be far more subtle and multi-faceted. Like animals, insects may be revered or reviled - and in some tribal communities insects may be the only source of food available. How people respond to, make use of, and relate to insects speaks volumes about their culture. In an effort to get to the bottom of our vexed relationship with the insect world, Brian Morris spent years in Malawi, a country where insects proliferate and people contend. In Malawi as in many tropical regions, insects have a profound impact on agriculture, the household, disease and medicine, and hence on oral literature, music, art, folklore, recreation and religion. Much of the complexity of human-insect relations rests on paradox: insects may represent the source of contagion, but they are also integral to many folk remedies for a wide range of illnesses. They may be at the root of catastrophic crop failure, but they can also be a form of sustenance.Weaving science with personal observations, Morris demonstrates a profound and intimate knowledge of virtually every aspect of human-insect relations. Not only is this book extraordinarily useful in terms of the more practical side of entomology, it also provides a wealth of information on the role of insects in cultural production. Malawian proverbs alone provide many such delightful examples - 'Bemberezi adziwa nyumba yake' ('The carpenter bee knows his own home'). This final volume in Morris' trilogy on Malawi's animal and insect worlds is certain to become a classic study of uncharted territory - the insect world that surrounds us and how we relate to it. Praise for The Power of Animals:Although based upon examination of a single culture, Morris incorporates ecological and anthropological concepts that expand this study of

The book is a new compendium in which leading termite scientists review the advances of the last 30 years in our understanding of phylogeny, fossil records, relationships with cockroaches, social evolution, nesting, behaviour, mutualisms with archaea, protists, bacteria and fungi, nutrition, energy metabolism,population and community ecology, soil conditioning, greenhouse gas production and pest status.
