“…First, individual metabolic rate scaled with different exponents in soil feeders and wood feeders. This contradicts suggestions that colonial organisms comply to a single, universal β , as often claimed for unitary organisms (Riveros & Enquist, ; Shik et al , ), and may partly explain why previous assessments of termite metabolic scaling produced conflicting results (Wood & Sands, ; Wheeler et al , ; Bignell et al , ; Jeeva et al , ; Riveros & Enquist, ). Beyond this, previous inconsistencies may also reflect relatively small sample sizes, biased taxonomic coverage, or a combination thereof.…”

“…This contrasts with the positive scaling between these traits reported for ants (King, ; Shik et al , ; Mason et al , ). Furthermore, estimates of individual‐level metabolic scaling across termite species are highly conflicting (Wood & Sands, ; Wheeler et al , ; Bignell et al , ; Jeeva et al , ) and a recent analysis even suggested that termite metabolic scaling differs fundamentally from that of other insects (Riveros & Enquist, ). Such uncertainties may be due to the marked diversification in lifestyle and diet that termites have experienced (Eggleton & Tayasu, ; Korb, ; Bourguignon et al , ), as suggested by the MLBH.…”

1. Metabolic rate (B) is a fundamental property of organisms, and scales with body mass (M) as B = αMβ. There has been much debate on whether scaling parameters should be viewed as constants or variables. However, there is increasing evidence that ecological differentiation can affect both α and β. 2. In colonial organisms such as social insects, individual metabolism is integrated at the colony level. Theory and data suggest that whole‐colony metabolism partly reflects individual‐level metabolic and life‐history scalings, but whether these have been affected by ecological diversification is little known. 3. Here, this issue was addressed using termites. Data from the literature were assembled to assess the interspecific scalings of individual metabolic rate with individual mass, and of individual mass with colony mass. Concurrently, it was tested whether such scalings were affected by two key ecological traits: lifestyle and diet. 4. Individual‐level metabolic scaling was affected by diet, with β = 1.02 in wood feeders and 0.60 in soil feeders. However, there was no difference in α. Further, individual mass scaled to the 0.25 power with colony mass, but forager species had larger colonies and smaller individuals relative to wood‐dwelling, sedentary ones, thus producing a grade shift. 5. Our results show that ecological diversification has affected fundamental metabolic and life‐history scalings in termites. Thus, theory on the energetics and evolution of colonial life should account for this variability.

“…Methane production rates vary drastically between species and depend predominantly upon the assay temperature (Fraser et al, 1986). Nitrogen fixation rates may depend upon the N availability in wood (Meuti et al, 2010), temperature and caste ratio (Breznak et al, 1973;Curtis & Waller, 1998 Figure 5 in Wheeler et al (1996). †Calculated using their reported fresh weight of 4.0 mg per termite.…”

Abstract. 1. Wood decomposition in temperate forests is dominated by termites, fungi, and some species of ants and beetles. Outside of urban areas, temperate termite ecology is largely unknown, particularly when compared to tropical termites and other temperate organisms in the functional guild of wood-decomposing animals.2. This review combines climate habitat modelling with knowledge of species physiology, behaviour, and community interactions to identify and prioritise future research on temperate termite ecology and biogeography.3. Using a correlative climate model, the regional distributions of three common temperate forest termite species are shown to correlate with different aspects of climate (e.g. mean versus minimum monthly temperature), but that overall their distributions within temperate systems correlate more strongly with temperature variables than with precipitation variables.4. Existing data are synthesised to outline how the subterranean, wood-nesting behaviour of most temperate forest termite species links their activity to an additional set of non-climate controls: wood type and tree species, soil depth, fungal activity, ant abundances and phenology, and competitive asymmetries among termite species.5. Although fine-scale estimates of temperate termite abundances are rare, we provide upper bounds on their ecosystem impacts and illustrate how their regional abundances may influence forest structure and habitat availability for other organisms.6. This review highlights that rigorous ecological studies in non-urban, intact ecosystems -with a particular focus on community interactions -are critically needed to accurately project future abundances, economic impacts, and ecosystem effects of temperate forest termites.

“…Drywood tennite detection relies mostly on wood probing and visual inspection. Canine olfaction and a variety of sound (electronic stethoscope) and metabolic gas/water vapor detection devices [ Each method has its shortcomings: inherent difficulties in using dogs [69], interfering audible background sounds, sporadic methane production [138], or insufficient moisture production by drywood termites. New technological advances in filtration of background acoustics and amplification of termite-generated acoustic emissions, however, have improved the prospect of detecting termites and other wood-feeding insects.…”

Abstract:Of the more than 2,300 tennite species in the world, 183 species are known to damage buildings and 83 species cause significant damage. Subterranean tennites, including mound building and arboreal species, account for 147 (80%) of the economically important species. The genus Coptotermes contains the largest number of pest species (28), whereas the genus Cryptotermes, especially Cr. brevis, is the most widely introduced. The world-wide economic impact figure of tennites is uncertain, but the control cost for tennite pests in the United States was estimated at $1.5 billion annually in 1994. Because of differences in their life histories, control measures differ between subterranean and drywood species. Insecticide barriers are used for exclusion of soil-borne subterranean tennites, whereas slow-acting baits are used for population control of subterranean tennite colonies in and near structures. Whole-structure treatments (fumigation and heat), compartmental treatments (heat or cold), and local treatments (wood surface treatments or insecticide injection) are the primary tools for drywood tennite control.
