SPIRACULAR CONTROL OF RESPIRATORY WATER LOSS IN FEMALE ALATES OF THE HARVESTER ANT POGONOMYRMEX RUGOSUS
It has been suggested that the discontinuous ventilation cycle (DVC) observed in many insects, including all ants described to date, is an adaptation to reduce respiratory water loss. To test thisExpand

Metabolic rate and respiratory gas-exchange patterns in tenebrionid beetles from the Negev Highlands, Israel.
This study correlates the pattern of external gas exchange with the diel activity of nine species of tenebrionid beetle from the Negev Desert, Israel. The study species are active throughout theExpand

The sealed subelytral cavity of many flightless beetle species is widely acknowledged to be an adaptation to water saving in arid-habitat species. However, this hypothesis relies on the acceptance ofExpand

Discontinuous gas exchange in dung beetles: patterns and ecological implications
Abstract This study correlates a distinctive pattern of external gas exchange, referred to as the discontinuous gas exchange cycle (DGC), observed in the laboratory, with habitat associations of fiveExpand

STANDARD AND EXERCISE METABOLISM AND THE DYNAMICS OF GAS EXCHANGE IN THE GIANT RED VELVET MITE, DINOTHROMBIUM MAGNIFICUM
Abstract Although many adult insects and adult, unfed ticks are known to exchange respiratory gases discontinuously, the respiratory physiology of other tracheate arthropods is almost unknown. InExpand

Shaken, not stirred: a serendipitous study of ants and earthquakes
SUMMARY There is anecdotal evidence for profound behavioral changes prior to and during earthquakes in many organisms, including arthropods such as ants. Behavioral or physiological analysis hasExpand

Energy cost of locomotion: Validation of laboratory data by in situ respirometry
The energy cost of activities central to overall fitness in most animals, such as pedestrian locomotion, is traditionally measured in the laboratory and then extrapolated to field conditions forExpand

The role of the mesothoracic spiracles in respiration in flighted and flightless dung beetles
SUMMARY The relative role of the mesothoracic and abdominal spiracles in respiration was examined using flow-through respirometry in four dung beetle species from different habitats. Two species ofExpand

Novel case of a tenebrionid beetle using discontinuous gas exchange cycle when dehydrated
Abstract In this study we show a link between the respiratory method and state of hydration in an arid dwelling tenebrionid beetle (Pimelia grandis). Dehydrated beetles use discontinuous gas exchangeExpand
