[Ab] Resumo:Aquatic insects play critical roles in freshwater ecosystems and temperature is a fundamental driver of species performance and distributions. However, the physiological mechanisms that determine the thermal performance of species remain unclear. Here we used a metabolomics approach to gain insights into physiological changes associated with a short-term, sublethal thermal challenge in the mayfly Neocloeon triangulifer (Ephemeroptera: Baetidae). Larvae were subjected to a thermal ramp (from 22 to 30°C at a rate of 1°C/h) and metabolomics analysis (both Nuclear Magnetic Resonance (NMR) Spectroscopy and Gas Chromatography coupled Time-of-Flight Mass Spectrometry (GC-TOF-MS)) indicated that processes related to energetics (sugar metabolism) and membrane stabilization primarily differentiated heat treated larvae from controls. Limited evidence of anaerobic metabolism was observed in the heat treated larvae at 30°C, a temperature that is chronically lethal to larvae.

[Ti] Título:De novo transcriptome of the mayfly Cloeon viridulum and transcriptional signatures of Prometabola.

[Ab] Resumo:Mayflies (Ephemeroptera) display many primitive characters and a unique type of metamorphosis (Prometabola). However, information on the genomes and transcriptomes of this insect group is limited. The RNA sequencing study presented here generated the first de novo transcriptome assembly of Cloeon viridulum (Ephemeroptera: Baetidae), and compared gene expression signatures among the young larva (YL), mature larva (ML), subimago (SI), and imago (IM) stages of this mayfly. The transcriptome, based on 88 Gb of sequence data, comprised a set of 81,185 high quality transcripts. The number of differentially expressed genes (DEGs) in YL vs. ML, ML vs. SI, and SI vs. IM, was 4,825, 1,584, and 1,278, respectively, according to the reads per kilobase of transcript per million mapped reads analysis, assuming a false discovery rate <0.05 and a fold change >2. Gene enrichment analysis revealed that these DEGs were enriched in the "chitin metabolic process", "germ cell development", "steroid hormone biosynthesis", and "cutin, suberine, and wax biosynthesis" pathways. Finally, the expression pattern of a selected group of candidate signature genes for Prometabola, including vestigial, methoprene-tolerant, wingless, and broad-complex were confirmed by quantitative real time-PCR analysis. The Q-PCR analysis of larval, subimaginal, and imaginal stages of C. viridulum suggests that the development of mayflies more closely resembles hemimetamorphosis than holometamorphosis.

[Ab] Resumo:A new species belonging to the subgenus Dilatognathus of the genus Choroterpes is described based on larvae collected from Andaman and Nicobar Islands. Choroterpes (Dilatognathus) nicobarensis n. sp. can be distinguished from all other species of Dilatognathus by the absence of a tusk on the maxillary apex, has ventro-apical flange and dentiseta directed distally, as in Choroterpes other than Dilatognathus. Choroterpes (Dilatognathus) nigella (Kang & Yang 1994) is newly recorded based on larvae collected in Arunachal Pradesh, Meghalaya and West Bengal. Remarks on the evolution of the mouth apparatus of the subgenus Dilatognathus are given.

[Ab] Resumo:The male imagoes, larvae, and eggs of Ameletus allengaensis sp. nov. and Ameletus sirotskii sp. nov. from the Russian Far East are described. Based on the structure of the male genitalia, the imago and larvae of A. allengaensis sp. nov. and A. sirotskii sp. nov. are similar to those of A. camtschaticus, but the discovery of these new species and separation from A. camtschaticus were confirmed by studies of the morphology of the larvae and male imago, as well as molecular analysis. Identity of various developmental stages of the new species were confirmed by analysis of the mitochondrial gene cytochrome oxidase 1 (COI) DNA barcode, which was also used to reconstruct the phylogenetic relationships within the genus Ameletus. The intraspecific sequence divergence based on the Kimura-2-parameter (K2P) distance ranged from 0.0-2.5%, whereas the interspecific sequence divergence based on the K2P distance ranged from 6.2-7.9% within A. sirotskii sp. nov., A. allengaensis sp. nov. and A. camtschaticus. Male imagoes of A. allengaensis sp. nov., A. sirotskii sp. nov., and A. camtschaticus can be distinguished by the size and location of small denticles on the ventral plate of the penis. The larvae of A. allengaensis sp. nov. differ from those of A. sirotskii sp. nov. by the size of gills I and II. In A. allengaensis sp. nov., gill I is almost twice as small as gill II; in A. sirotskii sp. nov., gill I is only slightly smaller than gill II. Both new species differ from A. camtschaticus by gill II, which does not have an anal rib on the anal margin.

[Ab] Resumo:The first phylogenetic study of Callibaetis Eaton indicated an unrevealed diversity in this genus, including four new species named as Callibaetis sp. A, B, C and D, and the undescribed nymph of Callibaetis (Abaetetuba) fasciatus (Pictet). Given that neither the nymph of C. (Ab.) fasciatus nor the four new species received a proper description, the objective of this study is to describe them. The nymph of C. (Ab.) fasciatus differs from the others species in the subgenus by the presence of one row of setae on basal part of inner-dorsal row of maxilla and metanotum without spines; Callibaetis sp. A is described as Callibaetis (Abaetetuba) cochlea sp. nov. and differs from the others species in the subgenus by having trapezoid segment III of labial palp in nymphs; Callibaetis sp. B is described as Callibaetis (Aiso) calophenigyn sp. nov. and differs from the others species in the subgenus by the absence of stout setae on dorsal surface of glossa in nymphs, and from the others species in the genus by the forewing with red C and Sc areas in female imago; Callibaetis sp. D is described as Callibaetis (Callibaetis) molinerii sp. nov. and differs from the others species in the subgenus, from South America, by the maxilla with tuft of stout setae on outer margin proximad of palp insertion and paraglossa without row of stout setae on ventral surface; Callibaetis sp. C is described as Callibaetis (Cunhaporanga) imperator sp. nov. and differs from the others species in the subgenus by the presence of a complete row of setae on outer margin of maxilla. Additionally, new keys for species of Callibaetis from South America are proposed.

[Ti] Título:Review of continental North and Central American Paracloeodes Day 1955 (Ephemeroptera: Baetidae), including description of a new species from Minnesota, U.S.A.

[Ab] Resumo:Paracloeodes Day is a western hemisphere genus with 20 species, but only three of these valid species are known from continental North and Central America. Based on available literature comparisons, species-level identifications of these three species can be difficult. Considering the apparent similarity between them, the main objective of this study was to examine type and other material housed in the Purdue Entomological Research Collection and the University of Minnesota in order to evaluate species status and to elucidate additional diagnostic characters. The evaluation resulted in validation of P. fleeki McCafferty & Lenat, P. lugoi Randolph & McCafferty and P. minutus (Daggy) and the confirmation of P. abditus Day as a junior synonym of P. minutus. Furthermore, we discovered a new species from the type locality of P. minutus. Paracloedes lotor n. sp. is described based on the nymph stage and a putative male imago from the Mississippi River in Minnesota. Paracloeodes lotor n. sp. differs from the other continental North and Central American species of the genus by the apical half of the paraglossa having an abrupt decrease in width (the "subtriangular" condition) in nymphs, and by having the posterior margin of the styliger plate with a small and pointed spine in the male imago. We provide a new identification key for nymphs of the four continental North and Central American species.

[Ti] Título:Genetic diversity and gene flow decline with elevation in montane mayflies.

[Ab] Resumo:Montane environments around the globe are biodiversity 'hotspots' and important reservoirs of genetic diversity. Montane species are also typically more vulnerable to environmental change than their low-elevation counterparts due to restricted ranges and dispersal limitations. Here we focus on two abundant congeneric mayflies (Baetis bicaudatus and B. tricaudatus) from montane streams over an elevation gradient spanning 1400 m. Using single-nucleotide polymorphism genotypes, we measured population diversity and vulnerability in these two species by: (i) describing genetic diversity and population structure across elevation gradients to identify mechanisms underlying diversification; (ii) performing spatially explicit landscape analyses to identify environmental drivers of differentiation; and (iii) identifying outlier loci hypothesized to underlie adaptive divergence. Differences in the extent of population structure in these species were evident depending upon their position along the elevation gradient. Heterozygosity, effective population sizes and gene flow all declined with increasing elevation, resulting in substantial population structure in the higher elevation species (B. bicaudatus). At lower elevations, populations of both species are more genetically similar, indicating ongoing gene flow. Isolation by distance was detected at lower elevations only, whereas landscape barriers better predicted genetic distance at higher elevations. At higher elevations, dispersal was restricted due to landscape effects, resulting in greater population isolation. Our results demonstrate differentiation over small spatial scales along an elevation gradient, and highlight the importance of preserving genetic diversity in more isolated high-elevation populations.
