“…Under global warming, low temperature requirements may drive stream insects toward higher latitudes or altitudes (Davis et al ; Parmesan ). However, significant geographical range shifts are unlikely for cold‐adapted species, such as Plecoptera (Fochetti ). It has been reported that 90% of Plecoptera can fly less than 60 m, and Ephemeroptera and Trichoptera travel even shorter distances (Petersen et al ).…”

Globally, the East Asian monsoon region is one of the richest environments in terms of biodiversity. The region is undergoing rapid human development, yet its river ecosystems have not been well studied. Global warming represents a major challenge to the survival of species in this region and makes it necessary to assess and reduce the potential consequences of warming on species of conservation concern. We projected the effects of global warming on stream insect (Ephemeroptera, Odonata, Plecoptera, and Trichoptera [EOPT]) diversity and predicted the changes of geographical ranges for 121 species throughout South Korea. Plecoptera was the most sensitive (decrease of 71.4% in number of species from the 2000s through the 2080s) order, whereas Odonata benefited (increase of 66.7% in number of species from the 2000s through the 2080s) from the effects of global warming. The impact of global warming on stream insects was predicted to be minimal prior to the 2060s; however, by the 2080s, species extirpation of up to 20% in the highland areas and 2% in the lowland areas were predicted. The projected responses of stream insects under global warming indicated that species occupying specific habitats could undergo major reductions in habitat. Nevertheless, habitat of 33% of EOPT (including two-thirds of Odonata and one-third of Ephemeroptera, Plecoptera, and Trichoptera) was predicted to increase due to global warming. The community compositions predicted by generalized additive models varied over this century, and a large difference in community structure in the highland areas was predicted between the 2000s and the 2080s. However, stream insect communities, especially Odonata, Plecoptera, and Trichoptera, were predicted to become more homogenous under global warming.

“…A moderately diverse order with more than 3,500 described species in 16 families (Fochetti & de Figueroa, 2007). In the only examined stonefly species, Perla burmeisteriana Claassen, 1936, very strong hybridization signals at the ends of metaphase chromosomes unambiguously prove the presence of the TTAGG telomeric sequence (Frydrychová et al, 2004).…”

Telomeres are terminal regions of chromosomes, which protect them from fusion with other chromosomes and stabilize their structure. Telomeres usually contain specific DNA repeats (motifs), which are maintained by telomerase, a kind of reverse transcriptase. In this review, we survey the current state of knowledge of telomere motifs in insects. Among Hexapoda, data on telomere composition are available for more than 350 species from 108 families and 25 orders. The telomere motif (TTAGG) n is considered ancestral for the class Insecta. However, certain insects have different and often unknown telomeric sequences. This apparently happens because telomerase-dependent mechanisms usually coexist with various means of alternative lengthening of telomeres as backup mechanisms of telomere maintenance. This coexistence can explain losses and reappearances of the TTAGG repeat and telomerase-dependent telomere replication in insect evolution. For example, a few higher taxa, such as Heteroptera (Hemiptera) and Hymenoptera, show presence of the (TTAGG) n motif in their basal clades as well as a subsequent loss and, at least in the Hymenoptera, independent reappearance of this repeat in some advanced groups. Analogously, most members of Coleoptera also retain the TTAGG repeat, although it is changed to TCAGG in certain families. Furthermore, the (TTAGG) n motif seems to have been irreversibly lost in the order Diptera. In this group, telomeric sequences are represented either by long terminal repeats or by retrotransposons. Retrotransposons are also interspersed with other telomeric sequences in many groups of insects. The accumulating data demonstrate that the class Insecta is substantially diverse in terms of its telomere structure. K E Y W O R D Schromosomes, FISH, insects, TTAGG, retrotransposons 128 |

“…[NI, not interpretable (main effects not interpretable when interactions are significant); ns, not significant; R 2 , coefficient of determination; PTV, pollution tolerance value; SCI, stream condition index] Although Leuctra is tolerant to acidic conditions (Kimmel and others, 1985;Fjellheim and Raddum, 1990), it is widely considered to be highly sensitive to anthropogenic stress in general-the tolerance value for Leuctra is zero (appendix 1), which is the most sensitive assignment possible on the 0-10 scale. Additionally, Leuctra is one of the most stenothermic genera of stonefly taxa, requiring a relatively narrow range of cool or cold water to complete their life cycle, and has been implicated as particularly vulnerable to warming water temperatures (Sweeney and others, 1992;Fochetti and Tierno De Figueroa, 2008;Tierno de Figueroa and others, 2010). Tolerance values were originally derived and modified from the seminal work by Lenat (1993) that based tolerance values on taxon-specific abundances across a water-quality gradient in North Carolina streams.…”
