“…Considering both genes together, uncorrected sequence divergences ranged from 1% between L. axilena, vibrans, auripennis, and jesseana to 15% between L. semifasciata, exusta, and deplanata. Both genes showed considerable A ϩ T nucleotide bias (Table 3), which is consistent with other insect mitochondrial genes (Crozier and Crozier, 1993;Simon et al, 1994;Frati et al, 1997;Chippindale et al, 1999). Using 2 tests implemented in PAUP 4.0b2 (Swofford, 1999), we were unable to reject homogeneity of base frequencies among sequences for either gene for all sites (COI:…”

“…The gene showing the strongest inconsistency with others, by several assessments, is 1216S (Tables 5, 6). Interestingly, two recent studies of intrageneric insect phylogeny also found disagreement among different mitochondrial genes, as indicated by conflict between nodes with strong bootstrap support (Caterino and Sperling 1999; Chippindale et al 1999). Other studies on multiple genes in animal mitochondria have revealed erratic patterns of base substitution that might limit usefulness for phylogeny reconstruction (e.g., Flook and Rowell 1997;Blouin et al 1998).…”

Cospeciation Between Bacterial Endosymbionts (Buchnera) and a Recent Radiation of Aphids (Uroleucon) and Pitfalls of Testing for Phylogenetic Congruence

Abstract. Previous studies of phylogenetic congruence between aphids and their symbiotic bacteria (Buchnera) supported long-term vertical transmission of symbionts. However, those studies were based on distantly related aphids and would not have revealed horizontal transfer of symbionts among closely related hosts. Aphid species of the genus Uroleucon are closely related phylogenetically and overlap in geographic ranges, habitats, and parasitoids. To examine support for congruence of phylogenies of Buchnera and Uroleucon, sequences from four mitochondrial, one nuclear, and one endosymbiont gene (trpB) were obtained. Congruence of phylogenies based on pooled aphid genes with phylogenies based on trpB was highly significant: Most nodes resolved by trpB corresponded to nodes resolved by the pooled aphid genes. Furthermore, no nodes were both inconsistent between the trees and strongly supported in both trees. Two kinds of analyses testing the null hypothesis of perfect congruence between pairwise combinations of datasets and tree topologies were performed: the Kishino-Hasegawa test and the likelihood-ratio test. Both tests indicated significant disagreement among most pairwise combinations of mitochondrial, nuclear, and symbiont datasets. Because rampant recombination among mitochondrial genomes of different aphid species is unlikely, inaccurate assumptions in the evolutionary models underlying these tests appear to be causing the hypothesis of a shared history to be incorrectly rejected. Moreover, trpB was more consistent with the aphid genes as a set than any single aphid gene was with the others, suggesting that the symbionts show the same phylogeny as the aphids. Overall, analyses support the interpretation that symbionts and aphids have undergone strict cospeciation, with no horizontal transmission of symbionts even among closely related, ecologically similar aphid hosts.

“…One monophyletic clade including seven taxa (I. damula, I. demorsa, I. denticollis, I. perparva I. posita posita, I. posita atezca and I. verticalis) and a clade including three species (I. erratica, I. cervula and I. gemina). The remaining North American species I. barberi, I. kellicotti, I. hastata, I. prognata and I. ramburii are thought to represent much earlier divergences in the group (Chippindale et al 1999). Recent phylogenetic work centred on the Eurasian ischnurans included 14 Eurasian, four North American, two African and two Australian species, and obtained phylogenetic patterns consistent with a recent diversification in this group (Dumont 2013).…”

Adaptive radiations have long served as living libraries to study the build-up of species richness; however, they do not provide good models for radiations that exhibit negligible adaptive disparity. Here, we review work on damselflies to argue that nonadaptive mechanisms were predominant in the radiation of this group and have driven species divergence through sexual selection arising from male-female mating interactions. Three damselfly genera (Calopteryx, Enallagma and Ischnura) are highlighted and the extent of (i) adaptive ecological divergence in niche use and (ii) nonadaptive differentiation in characters associated with reproduction (e.g. sexual morphology and behaviours) was evaluated. We demonstrate that species diversification in the genus Calopteryx is caused by nonadaptive divergence in coloration and behaviour affecting premating isolation, and structural differentiation in reproductive morphology affecting postmating isolation. Similarly, the vast majority of diversification events in the sister genera Enallagma and Ischnura are entirely driven by differentiation in genital structures used in species recognition. The finding that closely related species can show negligible ecological differences yet are completely reproductively isolated suggests that the evolution of reproductive isolation can be uncoupled from niche-based divergent natural selection, challenging traditional niche models of species coexistence.
