SummaryUnder laboratory conditions, meat ants can extract significant amounts of water from sand with 2% or 4% water content, or from nest soil with 4% water content, at a relatively modest metabolic cost. The biological significance of this ability is discussed.ZusammenfassungUnter Laborbedingungen können Ameisen der Gattung Iridomyrmex eine signifikante Menge Wasser mit relativ geringem Aufwand aus sand mit 2% bis 4% Wassergehalt oder aus Nestboden mit 4% Wassergehalt extrahieren.

Colony dispersion and relationships of meat antsIridomyrmex purpureus and allies in an arid locality in south Australia
The distributions of three “forms”, actually sibling species, of meat ant were studied near Morgan, South Australia, an area with mean annual rainfall of 230 mm, and it was suggested that the numbers of individuals and species of other taxa active on the soil surface, predominantly Collembola, were affected by numbers of ants.

Effects of microclimate and species identity on body temperature and thermal tolerance of ants (Hymenoptera: Formicidae)
The body temperatures recorded for deceased I. purpureus and M.‬brevinoda exposed to the sun exceeded their thermal tolerances, suggesting that these species utilise behavioural or physiological traits not present in deceased ant to regulate body temperature. Expand


On the Drinking of Soil Capillary Water by Spiders
1. A study has been made of the drinking of soil moisture by two species of lycosid spider. Carborundum powders have been used to provide a ‘soil’ of uniform particle size. 2. The rate of drinkingExpand
Absorption of water vapour from unsaturated air by Arenivaga sp. (polyphagidae, dictyoptera)
Abstract 1. 1. Dehydrated Arenivaga sp. nymphs and adult females absorb water vapour from relative humidities above 82·5 per cent at temperatures from 10–30°C. Adult Arenivaga males, PeriplanetaExpand
Water Balance in Desert Arthropods
There is probably no single respect in which all desert arthropods differ from insects of other environments, and perhaps a profitable way of viewing desert animals is to recognize that each is a whole organism with a specific collection of adaptations that must be consistent within themselves.

Estimation of Humidity with Cobalt Thiocyanate Papers and Permanent Colour Standards
The method of measuring relative humidity by matching the colours of tissue paper impregnated with cobalt thiocyanate has now been made more convenient by the commercial production of Impregnated paper and coloured glass standards, and it is shown that if special precautions are taken it can be used with considerable accuracy, particularly at relative humidities above 65 per cent.
