Data from: Galega orientalis is more diverse than Galega officinalis in Caucasus – whole-genome AFLP analysis and phylogenetics of symbiosis-related genes
Legume plants can obtain combined nitrogen for their growth in an efficient way through symbiosis with specific bacteria. The symbiosis between Rhizobium galegae and its host plant Galega is an interesting case where the plant species G. orientalis and G. officinalis form effective, nitrogen fixing, symbioses only with the appropriate rhizobial counterpart, R. galegae bv. orientalis and R. galegae bv. officinalis respectively. There is plenty of information available on the symbiotic properties of nitrogen fixing rhizobia, while more information is needed on the properties of the host plants. The Caucasus region in Eurasia has been identified as the gene centre (centre of origin) of G. orientalis, although both G. orientalis and G. officinalis can be found in this region. In this study, the diversity of these two Galega species in Caucasus was investigated to test the hypothesis that in this region G. orientalis is more diverse than G. officinalis. The amplified fragment length polymorphism (AFLP) fingerprinting performed here showed that the populations of G. orientalis and R. galegae bv. orientalis are more diverse than those of G. officinalis and R. galegae bv. officinalis respectively. These results are consistent with the centre of origin status of Caucasus for G. orientalis. Phylogenies of the symbiosis-related plant genes NORK and Nfr5 were congruent with the AFLP result from a diversity point of view. Finally, the results of this work indicate that the NORK and Nfr5 genes of Galega follow the same evolutionary pattern as conserved plant genes.
Data from: Phylogenetic patterns of skeletal morphometrics and pelvic traits in relation to locomotor mode in frogs
Frogs are one of the most speciose groups of vertebrate tetrapods (> 6200sp) with a diverse array of locomotor behaviours. Despite the impressive diversity in frog locomotor behaviours, there remains a paucity of information on the relationship between skeletal variation and locomotor mode in frogs and the evolutionary patterns in which these relationships are framed across the frog phylogeny. Our current understanding of the evolution of frog locomotion shows that hopping transitioned into jumping within the Neobatrachia where a variety of pelvic/hindlimb length patterns and locomotor niches have appeared, but this has yet to be studied over a broad taxonomic sample of frogs. Although limb length remains as the primary predictor of leaping performance, pelvic and sacral morphometrics have not been quantified in relation to limb proportions, body size and locomotor mode and previous studies have not sampled more than 24 families. We present a large-scale phylogenetic comparison of skeletal morphometrics in relation to locomotor mode in 188 genera from 37 families. Osteological variation in limb/pelvic girdle morphometrics and pelvic traits that are posited to be associated with locomotor mode were analysed to identify which aspects of the frog skeleton are the best descriptors of locomotor mode. Our results, contrary to previous work, reveal that the greatest axis of variation in frogs is represented by the shape of the sacrum with two pelvic morphologies evident in qualitative and quantitative ancestral trait reconstructions. Limb morphology was not significantly different across most locomotor modes, but we identified several outliers in hindlimb phylomorphospace. Patterns of sacral evolution together with hindlimb length outliers reveal how the general bauplan of this successful group of vertebrate tetrapods is constrained, has radiated and has converged on certain phenotypes to fill an array of locomotor modes.
Data from: Phylogenetic relationships and convergent evolution of ocean-shore ground beetles (Coleoptera: Carabidae: Trechinae: Bembidion and relatives)
Through phylogenetic analysis of seven genes, we show that there have been at least six independent entries into intertidal habitats in the history of bembidiine carabids, in the ancestors of: (i) Orzolina Machado, (ii) Bembidion (Desarmatocillenus Netolitzky), (iii) Bembidion laticeps (LeConte) + palosverdes Kavanaugh & Erwin, (iv) Bembidion laterale (Samouelle), (v) Bembidion umi Sasakawa and Bembidion quadriimpressum (Motschulsky) (which may represent two separate entries), and (vi) B. nigropiceum (Marsham). The following lineages are widely separated within the subtribe Bembidiina: Orzolina is sister to the genus Ocys Stephens; subgenus Desarmatocillenus appears to be sister to all Bembidion Latreille excluding subgenus Phyla Motschulsky; B. laticeps + B. palosverdes is a clade in the Bembidion series; B. laterale is a member of the Princidium Motschulsky complex; B. umi and B. quadriimpressum are related to the Nearctic Clade of the Ocydromus Clairville complex; B. nigropiceum is sister to B. praeustum Dejean among sampled species. There are three separate lineages of ocean‐shore bembidiines that are known to prey on amphipods, and adults of these lineages [Bembidion (Desarmatocillenus), B. laterale, and B. mandibulare Solier] have unusually wide heads with long mandibles. Also common among independent lineages restricted to ocean shores are prominent front angles of the prothorax, larger numbers of setae on the elytral disc, a notable sinuation in the margin of each elytron near its apex, and short, wide mesotarsi. The reasons for the repeated evolution of these features are not evident. Our results also suggest that inland species of the Nearctic Clade may have arisen from an ocean‐shore ancestor. The close genetic similarities between the gravel river shore dwelling B. praeustum and the intertidal specialist B. nigropiceum suggest that the striking morphological adaptations of B. nigropiceum to the intertidal zone arose rapidly. We make one nomenclatural change: we resurrect the subgenus Lymneops Casey to accommodate B. palosverdes and B. laticeps.
