Soil macroinvertebrate communities have been assessed worldwide using the standard ISO/TSBF sampling procedure. The Macrofauna database currently comprises 3694 sites distributed throughout 41 countries, from 55º S latitude to 57ºN, sea level to over 4000m in elevation, in total annual total rainfall regimes between 500 and >3000mm and 5 to 32ºC mean temperature. These communities are significantly influenced by climatic parameters, soil texture and vegetation cover. Abundance and diversity were highest in tropical rain forests...

Interactions between silicon and alkaloid defences in endophyte-infected grasses and the consequences for a folivore

1. Grasses have developed a wide range of morphological and physiological mechanisms to resist herbivory. For instance, they accumulate silicon (Si) in tissue, as physical defence, and associate symbiotically with foliar Epichloë-endophytes that provide chemical defence via antiherbivore alkaloids. Recent evidence showed that some Epichloë-endophytes increase foliar Si in forage grasses; however, it is unknown whether this impacts insect herbivores. Furthermore, while Si is primarily a physical defence, it also affects production of plant defensive...
