Narrow thresholds of canopy disturbance determine the microclimate buffering potential of tropical forests

Michael J. W. Boyle, Joseph R. Williamson, Stephen J. Rossiter, Marion Pfeifer et autres

The importance of protecting logged and recovering tropical forests has gained much attention. Disturbed forests can, however, have hotter microclimates, exacerbating the effects of future climate change. Using thermal imaging we captured understory surface temperatures along a gradient of tropical forest disturbance, …

The illusion of infinity: Acoustic black holes in wood deceive termites

Can Nerse, Shahrokh Sepehrirahnama, Joseph C. S. Lai, Theodore A. Evans et autres

Vibrational signals produced during feeding are fundamental to termite behaviour, yet their function in regulating collective foraging remains unclear. In this study, we combine bioassays, micro-CT imaging, and elastic wave modelling to investigate how the subterranean termite Coptotermes acinaciformis evaluates wood through …

Termite Vibration Sensing: The Chordotonal Organs and Their Appendages

Travers M. Sansom, Joseph C. S. Lai, Benjamin Halkon, Theodore A. Evans et autres

Eusocial insects like termites and ants use diverse communication methods, including pheromones, sound, and vibrations. Termites, blind and with fewer glands, rely heavily on vibrations for foraging, communication, and predator avoidance. Their appendages detect subtle signals amid noise, though the underlying physiological …

Helox suggests advective ventilation of the insect tracheal system during discontinuous gas exchange

Waseem Abbas, Philip Carew Withers, Theodore A. Evans

About a century ago, Krogh theorised that gas exchange by insects between spiracles and tissues occurs by diffusion without an advective (convective) component but physiological data supporting the relative roles of diffusion and advection are unclear, especially for small, flightless insects that …

The relative influences of long‐term fire management and woody cover on termite abundance and activity in an Australian tropical savanna

Ellen Rochelmeyer, Theodore A. Evans, Paul Eggleton, Brett P. Murphy et autres

Abstract Tropical savannas typically experience high fire frequencies, with prescribed fire commonly used as a management tool. Termites play an important role in the ecological functioning of tropical savannas, yet we have a limited understanding of how fire affects these important ecosystem …

The “hidden workers”: livestock farmers’ perceptions of ecosystem services provided by dung beetles

Marcela Del Carmen Vieira, Benedict White, Jacob D. Berson, Fiona Dempster et autres

Non-native dung beetles were introduced to Australian agricultural systems to provide ecosystem services, such as pasture cleaning and to control dung-breeding flies, which benefit particularly livestock farmers. A variety of studies have explored the interactions between dung beetles and livestock systems worldwide. …

DESIGN OF AN INSTRUMENTED SANDPIT TO MONITOR SUBTERRANEAN TERMITE AND ANT ACTIVITY IN VIBRATION BIOASSAYS

Can Nerse, Sebastian M. Oberst, J. Lai, Theodore A. Evans

Termites are known to use vibrational communication in the form of alarm, walking and feeding signals, for the survival of the nest against predators and competitors, as well as unfavourable microclimate conditions. However, less is known about the mechanism of sensing and …

TERMITES THRIVE BY USING VIBRATIONS

Joseph C. S. Lai, Sebastian M. Oberst, Theodore A. Evans

Termites are notoriously cryptic: infestations in houses are often discovered when an apparently intact timber object collapses, the archetypal 'falling through the floor boards'. This behaviour is adaptive because remaining undiscovered is the termite's primary defence against predators. However, being cryptic severely …
