“…5A). This is consistent with Oikawa et al (2006) showing no significant correlation between mass-adjusted oxygen consumption and thermal tolerance among 28 species belonging to Drosophila and its related genera. This may be because cold tolerance is a complex trait influenced by various factors such as presence of cryoprotective agents, antifreeze proteins, ice-nucleating proteins and heat-shock proteins and modified condition of cell membrane (Chown and Nicolson, 2004, for review;Lee and Denlinger, 2010;Michaud and Denlinger, 2010;Koštál, 2010;Chown and Sinclair, 2010;Huey, 2010;Overgaard et al, 2010;Storey and Storey, 2012).…”

“…In general, metabolic rate decreases as the ambient temperature decreases in ectothermic animals including Drosophila (Fleming and Miquel, 1983;Berrigan and Partridget, 1997;Oikawa et al, 2006), and this tendency is regarded as a response to temperature changes (e.g., Gillooly et al, 2001). However, in the studies with Drosophila and the tsetse fly species mentioned above (Berrigan, 1997;Terblanche et al, 2005;Terblanche and Chown, 2006), significant effects of the rearing temperature on the response to temperature changes were also suggested.…”

Cold tolerance and metabolic rate increased by cold acclimation in <i>Drosophila albomicans</i> from natural populations

Cold acclimation is one of the important factors in temperature adaptation for insects needing to make rapid adjustment to the seasonal temperature changes in their living environment. In a fruit fly species, Drosophila albomicans, which has a tropical origin and currently has a wide geographic distribution extended into Asian temperate regions, cold tolerance in terms of survival time at 1°C of adult flies reared at 25°C was substantially improved by a cold acclimation at 20°C for several days. Examining 29 isofemale lines from widely distributed natural populations, we observed a substantial variation in their acclimation response. However, the acclimation response was not necessarily stronger in the strains from the recently colonized temperate regions. A significantly stronger acclimation response was detected in male flies of the temperate strains when compared to those of the tropical strains. D. albomicans also showed stronger cold tolerance compared to its closely related species belonging to the D. nasuta subgroup. Among these strains, we detected a strong positive correlation between the cold tolerance change and the metabolic rate change upon the cold acclimation, suggesting their strong physiological association regulated by common genetic factors, which may have been the target of natural selection for the temperature adaptation. The response to deacclimation and reacclimation suggested that a systematic change in gene expressions is the main molecular mechanism for the cold acclimation to have effects on the cold tolerance and metabolic rate changes.

“…However, these results are controversial because not all studies find evidence for MCA. For example, at the intraspecific level, Berrigan and Partridge (1997) found no relationship between the slope of the MR-T relationship and latitude in Drosophila melanogaster (and see Oikawa et al 2006). By contrast, at the interspecific level, Mackay (1982) found that high-altitude species of Pogonomyrmex ants have increased metabolic rates and sensitivity to temperature compared with low-elevation species.…”

The evolution of metabolic rate-temperature (MR-T) reaction norms is of fundamental importance to physiological ecology. Metabolic cold adaptation (MCA) predicts that populations or species from cooler environments will have either a higher metabolic rate at a common temperature or steeper MR-T relationships, indicating greater sensitivity of respiratory metabolism to temperature. Support for MCA has been found in some insect species by comparing species or populations differing in latitude. However, the generality of these findings are contentious, with most studies either unable to account for phenotypic plasticity or the evolutionary relatedness of species or populations. Hence, the importance of MCA is vigorously debated from both evolutionary and ecological perspectives. Furthermore, few species, particularly from tropical environments, have been shown to differ in MR-T sensitivity along altitudinal temperature gradients. Here, using four populations of tsetse flies (Glossina pallidipes, Diptera: Glossinidae) from thermally distinct geographic regions, we test the hypothesis that there is evolved variation in MR-T relationships to cold climates. We found that a high-altitude equatorial population from a cool habitat has a steeper MR-T reaction norm. By contrast, other populations from warmer environments in East Africa do not differ with respect to their MR-T reaction norms. Squared-change parsimony analyses, based on the combined mitochondrial 16S rDNA ribosomal subunit and cytochrome c oxidase subunit I (COI), support the hypothesis of adaptive differentiation of MR-T reaction norms in the cool-climate population. Seasonal adjustments or laboratory-temperature-induced phenotypic plasticity changed the intercept of the reaction norm rather than the slope, and thus the observed intraspecific variation in slopes of MR-T reaction norms could not be accounted for by phenotypic plasticity. These results therefore suggest evolutionary adaptation of MR-T reaction norms to cool climates (<22 degrees C) in tsetse and provide novel support for MCA within an insect species.

Exposure to low temperatures requires an organism to overcome physiological challenges. New Zealand wētā belonging to the genera Hemideina and Deinacrida are found across a wide range of thermal environments and therefore subject to varying selective pressures. Here we assess the selection pressures across the wētā phylogeny, with a particular emphasis on identifying genes under positive or diversifying selection. We used RNA-seq to generate transcriptomes for all 18 Deinacrida and Hemideina species. A total of 755 orthologous genes were identified using a bidirectional best-hit approach, with the resulting gene set encompassing a diverse range of functional classes. Analysis of ortholog ratios of synonymous to nonsynonymous amino acid changes found 83 genes that are under positive selection for at least one codon. A wide variety of Gene Ontology terms, enzymes, and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways are represented among these genes. In particular, enzymes involved in oxidative phosphorylation, melanin synthesis, and free-radical scavenging are represented, consistent with physiological and metabolic changes that are associated with adaptation to alpine environments. Structural alignment of the transcripts with the most codons under positive selection revealed that the majority of sites are surface residues, and therefore have the potential to influence the thermostability of the enzyme, with the exception of prophenoloxidase where two residues near the active site are under selection. These proteins provide interesting candidates for further analysis of protein evolution.
