The evolutionary speed hypothesis (ESH) proposes a causal mechanism for the latitudinal diversity gradient. The central idea of the ESH is that warmer temperatures lead to shorter generation times and increased mutation rates. On an absolute time scale, both should lead to an acceleration of selection and drift. Based on the ESH, we developed predictions regarding the distribution of intraspecific genetic diversity: populations of ectothermic species with more generations per year owing to warmer ambient temperatures should be more differentiated from each other, accumulate more mutations and show evidence for increased mutation rates compared with populations in colder regions. We used the multivoltine insect species Chironomus riparius to test these predictions with cytochrome oxidase I (COI) sequence data and found that populations from warmer regions are indeed significantly more differentiated and have significantly more derived haplotypes than populations from colder regions. We also found a significant correlation of the annual mean temperature with the population mutation parameter u that serves as a proxy for the per generation mutation rate under certain assumptions. This pattern could be corroborated with two nuclear loci. Overall, our results support the ESH and indicate that the thermal regime experienced may be crucially driving the evolution of ectotherms and may thus ultimately govern their speciation rate.

“…The cytogenetic distances, D cg (Nei 1972) between C. plumosus populations from different continents are larger than between the West Siberian populations; however, they yet fall within range characteristic of the cytogenetic differences between the populations of this species (Gunderina et al 1999a;Kiknadze et al 2000). The genetic distances, GD (Link et al 1995) between these populations fit the level of interpopulation genetic differences within a species (Gunderina et al 2009). Independently of geographic distance between populations and the degree of differentiation of their genetic and cytogenetic structures, all the C. plumosus larvae gave the amplicon MAR2 in the PCR with the primer pair plu107F/plu363R.…”

“…As is known, cytogenetic and genetic structures of natural populations of chironomid species considerably vary within their geographic range (Gunderina et al 1999a(Gunderina et al , 1999b(Gunderina et al , 2008(Gunderina et al , 2009. Therefore, the C. plumosus and C. balatonicus larvae from geographically distant populations were used to test species specificity of the designed primers.…”

Species-specific PCr primers for identification of the sibling species Chironomus plumosus (linnaeus, 758) and Chironomus balatonicus (devai, wuelker et Scholl, 83) (Chironomidae, diptera) larissa I. gunderina Gunderina LI. 2012. Species-specific PCR primers for identification of the sibling species Chironomus plumosus (Linnaeus, 1758) and Chironomus balatonicus (Devai, Wuelker et Scholl, 1983) (Chironomidae, Diptera). Fauna norvegica 31: 151-157. Applicability of the polymerase chain reaction (PCR) with species-specific primers to obtaining molecular markers for identification of the sibling species of Chironomus plumosus group-C. plumosus and C. balatonicus-has been estimated. The nucleotide sequences of internal transcribed spacer (ITS) from the locus encoding ribosomal RNA (rRNA) were used as the source for designing the species-specific primers. The primers allowing for identification of C. plumosus and C. balatonicus were constructed. One primer pair (plu107F/plu363R) gives the PCR product MAR2, specific of C. plumosus, and the other (bal86F/plu363R), the PCR product MAR6, specific of C. balatonicus. The testing involving 18 species of the genus Chironomus confirmed the specificity of the primers. The results suggest that the PCR with species-specific primers is promising for construction of molecular markers for identification not only of these two, but also of other Chironomus species.
