“…Secondly, when bees loose water, they also cool down through evaporation enthalpy, which might be critical in environments with low ambient temperatures. We also found a correlation between temperature and CHC composition as shown by Michelutti et al (2018). Therefore, probably temperature and relative humidity are both important drivers with regard to water loss.…”

Elevational gradients challenge all organisms as they are confronted with rapid abiotic and biotic changes over short geographic distances. These changes primarily, but not exclusively, involve abiotic shifts in temperature, humidity, precipitation, partial pressure of atmospheric gases, UV radiation, atmospheric turbulence, and wind speed (Barry, 1992). Consequences for organisms include reduced suitable time periods for development, foraging, and reproduction, but also changes in food quality and pressure by natural enemies and pathogens (Hodkinson, 2005).Several morphological, life history, and behavioral adaptations to the changing environment along elevational gradients have been investigated, such as changes in body, wing size, number of generations, or activity times (

“…Therefore, the sensation-related genes may play important roles in rapid response to heat stress. Heat induces changes in cuticle, such as cuticular hydrocarbon profile [25,43,44]. After multigenerational heat acclimation, the sensitivity of cuticle to heat may become lower than before, and therefore, the heat-induced DEGs are not enriched in the GO term of structural consitituent of cuticle anymore.…”

Background: The rice leaf folder Cnaphalocrocis medinalis Güenée is a serious insect pest of rice in Asia. This pest occurs in summer, and it is sensitive to high temperature. However, the larvae exhibit heat acclimation/adaptation. To understand the underlying mechanisms, we established a heat-acclimated strain via multigenerational selection at 39°C. After heat shock at 41°C for 1 h, the transcriptomes of the heat-acclimated (S-39) and unacclimated (S-27) larvae were sequenced, using the unacclimated larvae without exposure to 41°C as the control. Results: Five generations of selection at 39°C led larvae to acclimate to this heat stress. Exposure to 41°C induced 1160 differentially expressed genes (DEGs) between the heat-acclimated and unacclimated larvae. Both the heatacclimated and unacclimated larvae responded to heat stress via upregulating genes related to sensory organ development and structural constituent of eye lens, whereas the unacclimated larvae also upregulated genes related to structural constituent of cuticle. Compared to unacclimated larvae, heat-acclimated larvae downregulated oxidoreductase activity-related genes when encountering heat shock. Both the acclimated and unacclimated larvae adjusted the longevity regulating, protein processing in endoplasmic reticulum, antigen processing and presentation, MAPK and estrogen signaling pathway to responsed to heat stress. Additionally, the unacclimated larvae also adjusted the spliceosome pathway, whereas the heat-acclimated larvae adjusted the biosynthesis of unsaturated fatty acids pathway when encountering heat stress. Although the heat-acclimated and unacclimated larvae upregulated expression of heat shock protein genes under heat stress including HSP70, HSP27 and CRYAB, their biosynthesis, metabolism and detoxification-related genes expressed differentially. Conclusions: The rice leaf folder larvae could acclimate to a high temperature via multigenerational heat selection. The heat-acclimated larvae induced more DEGs to response to heat shock than the unacclimated larvae. The changes in transcript level of genes were related to heat acclimation of larvae, especially these genes in sensory organ development, structural constituent of eye lens, and oxidoreductase activity. The DEGs between heat-acclimated and unacclimated larvae after heat shock were enriched in the biosynthesis and metabolism pathways. These results are helpful to understand the molecular mechanism underlying heat acclimation of insects.

“…Even in more distantly related insect taxa, interesting similarities to our findings have been discovered, implying more general effects of climatic factors on CHC compositions conserved over larger phylogenetic boundaries. For instance, in three social wasp species of the subfamily Polistinae, temperature was also positively correlated with relative amounts of nalkanes, but negatively with relative amounts of methyl alkanes (Michelutti et al 2018). Even more distantly related and beyond the Hymenoptera, the West Indian drywood termite, Cryptotermes brevis, exhibits very different CHC profiles than L. humile, with n-alkenes constituting the most prevalent compound class as opposed to the least prevalent one in our study (Woodrow et al 2000, see Fig.…”

Desiccation Resistance and Micro-Climate Adaptation: Cuticular Hydrocarbon Signatures of Different Argentine Ant Supercolonies Across California

Cuticular hydrocarbons (CHCs), the dominant fraction of the insects' epicuticle and the primary barrier to desiccation, form the basis for a wide range of chemical signaling systems. In eusocial insects, CHCs are key mediators of nestmate recognition, and colony identity appears to be maintained through a uniform CHC profile. In the unicolonial Argentine ant Linepithema humile, an unparalleled invasive expansion has led to vast supercolonies whose nestmates can still recognize each other across thousands of miles. CHC profiles are expected to display considerable variation as they adapt to fundamentally differing environmental conditions across the Argentine ant's expanded range, yet this variation would largely conflict with the vastly extended nestmate recognition based on CHC uniformity. To shed light on these seemingly contradictory selective pressures, we attempt to decipher which CHC classes enable adaptation to such a wide array of environmental conditions and contrast them with the overall CHC profile uniformity postulated to maintain nestmate recognition. n-Alkanes and n-alkenes showed the largest adaptability to environmental conditions most closely associated with desiccation, pointing at their function for water-proofing. Trimethyl alkanes, on the other hand, were reduced in environments associated with higher desiccation stress. However, CHC patterns correlated with environmental conditions were largely overriden when taking overall CHC variation across the expanded range of L. humile into account, resulting in conserved colony-specific CHC signatures. This delivers intriguing insights into the hierarchy of CHC functionality integrating both adaptation to a wide array of different climatic conditions and the maintenance of a universally accepted chemical profile.
