Colony-age-dependent variation in cuticular hydrocarbon profiles in subterranean termite colonies
<p>Cuticular hydrocarbons (CHCs) have, in insects, important physiological and ecological functions, such as protection against desiccation and as semiochemicals in eusocial taxa, including termites. CHCs are, in termites, known to vary qualitatively and/or quantitatively among species, populations, or seasons. Changes to hydrocarbon profile composition have been linked to varying degrees of aggression between termite colonies, although the variability of results among studies suggests that additional factors might have been involved. One source of variability may be colony age; however, this factor has never been investigated. We studied caste-specific patterns of CHC profiles in Coptotermes gestroi colonies of four different age classes (6, 18, 30, and 42 months). The CHC profiles were variable among castes in the youngest colonies, but progressively converged with increasing colony age. Young colonies had a less-defined CHC identity compared to older ones, which likely obscures the colony's ability to detect non-nestmates. Our data suggest that there is no selective pressure on an early-defined colony CHC profile, potentially allowing incipient colonies to merge non-agonistically with competing conspecifics as an indirect result. </p>

Figure 1 in Can we agree on an ecological classification of subterranean animals?
Figure 1. Controversy of troglomorphy. The Niphargus case. (A) Niphargus hebereri Schellenberg (strictly cavernicolous); (B) N. stygius (Schiödte) (from caves and rock fissures); (C) N. valachicus Dobreanu et Manolache (from lowland pools and ditches); (D) N. krameri Schellenberg (from small surface streams, sometimes in caves). Scale bar approximately 10 mm. Specimen (D) preserved. Note that the absence of eyes is a primary character of the genus; absence of pigmentation is a troglomorphic character of both cave species. The strictly subterranean N. hebereri is not troglomorphic in its body proportions while the epigean N. krameri seemingly is.
