The phylogeny of Orthoptera inferred from mtDNA and description of Elimaea cheni （Tettigoniidae： Phaneropterinae） mitogenome

The complete 15,831 bp nucleotide sequence of the mitochondrial genome from Elimaea cheni(Phaneropterinae)was determined.The putative initiation codon for cox1 was TTA.The phylogeny of Orthoptera based on different mtDNA datasets were analyzed with maximum likelihood(ML)and Bayesian inference(BI).When all 37 genes(mtDNA)were analyzed simultaneously,the monophyly of Caelifera and Ensifera were recovered in the context of our taxon sampling.The phylogeny of Orthoptera was largely consistent with previous phylogenetie hypotheses.Rhaphidophoridae to be a sister group of Tettigoniidae,and the relationships among four subfamilies of Tettigoniidae were(Phaneropterinae+(Conocephalinae+(Bradyporinae+Tettigoniinae))).Pyrgomorphidae was the most basal group of Caelifera.The relationships among six acridid subfamilies were(Oedipodinae+(Acridinae+(Gomphocerinae+(Oxyinae+(Calliptaminae +Cyrtacanthaeridinae))))).However,we did not recover a monophyletic Grylloidea.Myrmecophilidae clustered into one clade with Gryllotalpidae instead of with Gryllidae.ML and BI analyses of all protein coding genes(using all nucleotide sequence data or excluding the third codon position,and amino acid sequences)revealed a topology identical to that of the entire mtDNA genome dataset.However,22 tRNAs genes excluding the DHU loop and T()C loop(TRNA),and two rRNA genes(RRNA)perform poorly when analyzed as single dataset.Our results suggest that the best phylogenetie inferences were ML and BI methods based on total mtDNA.Excluding tRNA genes,rRNA genes and the third codon position of protein coding genes from dataset and converting nucleotide sequences to amino acid sequences do not positively affect phylogenetic reconstruction.

Humidity and seasonality drives body size patterns in males of the bush cricket Isophya rizeensis Sevgili, 2003 （Orthoptera： Tettigoniidae： Phaneropterinae）

Two primary patterns of body size variation have been recorded in ectotherms in relation to latitudinal/altitudinal shifts. In some, body size increases with increasing latitude/altitude whereas, in others, body size decreases with increasing latitude/altitude. This clinal variation is generally assumed to be caused by local adaptation to environmental conditions however the selective variable（s） （temperature, humidity, diet quality, etc.） is still heavily debated. Here we investigate geographic variation in body size of dark and pale color morphs of males of the bush-cricket lsophya rizeensis collected from 15 locations along an elevation gradient ranging from 350 to 2 500 m. Using an information theoretical approach we evaluate the relative support of four different hypotheses （the temperature size rule, the moisture gradient hypothesis, the seasonal constraint hypothesis, and the primary productivity hypothesis） explaining body size variation along the altitudinal gradient. Body size variation in pale color morphs showed a curvilinear relationship with altitude while dark color morphs showed no variation in body size. Body size variation in pale color morphs was highly correlated with precipitation and temperature seasonality values thus giving strong support for the moisture gradient and seasonal constraint hypothesis. Our results reinforce the importance of gradients in humidity and seasonality over temperature in the creation of altitudinal body size clines and the role of selection for resistance to stress factors in the establishment of these clines. Whether a body size cline is observed or not might also depend on the phenotypic properties of the individuals, like coloration.
