  • The phylogenetic significance of leaf anatomical traits of southern African Oxalis. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 22; 16(1):225
  • Jooste M, Dreyer LL, Oberlander KC
  • CONCLUSIONS: Major and unexpected findings include the transition from ancestral hypostomatic leaflets to adaxially-located stomata in the vast majority of southern African Oxalis, the loss of semi-swollen AB epidermal cells and the gain of swollen adaxial and abaxial epidermal cells in selected clades, and multiple changes from ancestral bifacial mesophyll to isobilateral or homogenous mesophyll types. The information gathered in this study will aid in the taxonomic revision of this speciose member of the Greater Cape Floristic Region and provide a basis for future hypotheses regarding its radiation.
  • Phylogenomic analysis of carangimorph fishes reveals flatfish asymmetry arose in a blink of the evolutionary eye. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 21; 16(1):224
  • Harrington RC, Faircloth BC, … Friedman M
  • CONCLUSIONS: The longstanding uncertainty in phylogenetic hypotheses for flatfishes and their carangimorph relatives highlights the limitations of smaller molecular datasets when applied to successive, rapid divergences. Here, we recovered significant support for flatfish monophyly and relationships among carangimorphs through analysis of over 1,000 UCE loci. The resulting time-calibrated phylogeny points to phenotypic divergence early within carangimorph history that broadly matches with the predictions of adaptive models of lineage diversification.
  • Recent horizontal transfer, functional adaptation and dissemination of a bacterial group II intron. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 20; 16(1):223
  • LaRoche-Johnston F, Monat C, Cousineau B
  • CONCLUSIONS: This work shows that Ll.LtrB and Ef.PcfG are homologous and have a common origin resulting from a recent lateral transfer event followed by further adaptation to the new target site and/or host environment. We hypothesize that Ef.PcfG is the ancestor of Ll.LtrB and was initially acquired by L. lactis, most probably by conjugation, via a single event of horizontal transfer. Strong selective pressure on homing site invasion efficiency then led to the emergence of beneficial point mutations in the IEP, enabling the successful establishment and survival of the group II intron in its novel lactococcal environment. The current colonization state of Ll.LtrB in L. lactis was probably later achieved through recurring episodes of conjugation-based horizontal transfer as well as independent intron mobility events. Overall, our data provide the first evidence of functional adaptation of a group II intron upon invading a new host, offering strong experimental support to the theory that bacterial group II introns, in sharp contrast to their organellar counterparts, behave mostly as mobile elements.
  • Shape, colour plasticity, and habitat use indicate morph-specific camouflage strategies in a marine shrimp. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 18; 16(1):218
  • Duarte RC, Stevens M, Flores AA
  • CONCLUSIONS: Results suggest that H shrimp utilise a camouflage strategy specialised to a limited number of backgrounds at any one time, whereas ST individuals comprise a phenotype with more generalist camouflage (transparency) linked to a more generalist background utilisation. The coexistence within a population of distinct morphotypes with apparently alternative strategies of habitat use and camouflage may reflect differential responses to substantial seasonal changes in macroalgal cover. Our findings also demonstrate how colour change, behaviour, morphology, and background use all interact in achieving camouflage.
  • Genotype diversity in the honey bee parasite Nosema ceranae: multi-strain isolates, cryptic sex or both? [Journal Article]
  • BEBMC Evol Biol 2016 Oct 18; 16(1):216
  • Sagastume S, Martín-Hernández R, … Henriques-Gil N
  • CONCLUSIONS: The N. ceranae isolates from honey bees correspond to genotypically distinct populations, revealing that individual honey bees may not be infected by a particular clone but rather, a pool of different strains. Homologous recombination implies the existence of a cryptic sex cycle yet to be described in N. ceranae. There are no diagnostic alleles associated with Australian or European origins, nor are there differences between the two hosts, A. cerana and A. mellifera, supporting the absence of biological barriers for N. ceranae transmission. Diversity is high among microsporidia of both these origins, and the maintenance of a high heterozygosis in the recently invaded European populations, could hypothetically underlie the stronger virulence of N. ceranae observed in A. mellifera.
  • Genetic and phenotypic variation along an ecological gradient in lake trout Salvelinus namaycush. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 19; 16(1):219
  • Baillie SM, Muir AM, … Bentzen P
  • CONCLUSIONS: We provide evidence of reductions in gene flow and divergent natural selection associated with water depth in Lake Superior. Such information is relevant for documenting intraspecific biodiversity in the largest freshwater lake in the world for a species that recently lost considerable genetic diversity and is now in recovery. Unknown is whether observed patterns are a result of an early stage of incipient speciation, gene flow-selection equilibrium, or reverse speciation causing formerly divergent ecotypes to collapse into a single gene pool.
  • The first fossil salmonfly (Insecta: Plecoptera: Pteronarcyidae), back to the Middle Jurassic. [Journal Article]
  • BEBMC Evol Biol 2016 Oct 18; 16(1):217
  • Cui Y, Béthoux O, … Ren D
  • CONCLUSIONS: The first discovery of a fossil member of the Pteronarcyidae demonstrates that the corresponding lineage is not a very recent offshoot but was already present ca. 165 million years ago. This discovery concurs with the view that divergence of most stonefly families took place very early, probably in the Triassic, or even in the Permian. This contribution demonstrates the need for (re-)investigations of the systematics of fossil stoneflies to refine divergence date estimates for Plecoptera lineages.
