Phylogenetic relationships within the polyopisthocotylean monogeneans (Platyhelminthes) inferred from partial 28S rDNA sequences.
TLDR
The polytomy between Gastrocotylinea, Discocoty linea and MicrocotylineA is partially resolved in this study for the first time: the Gastrocodlinea are the sister-group of an unresolved group including the MicrocotYlinea and Plectanocotylidae. Expand

TLDR
This work recommends how best to exploit hyperdiverse populations for analysis, for example, in quantifying the impact of noncrossover recombination in genomes and for determining the identity and micro‐evolutionary selective pressures on noncoding regulatory elements. Expand
Comparison of ribosomal DNA sequences of Lamellodiscus spp. (monogenea, diplectanidae) parasitising Pagellus (sparidae, teleostei) in the North Mediterranean Sea: species divergence and
TLDR
The ITS1 sequences appear to be highly variable among Lamellodiscus species, except L.virgula and L.obeliae, suggesting an old divergence time or a rapid molecular evolution within this genus, and this fish-parasite association seems to exhibit coevolutionary interactions. Expand
Specialist versus generalist life histories and nucleotide diversity in Caenorhabditis nematodes
TLDR
This work characterize sequence variation for 20 nuclear loci to investigate how C. japonica's life history shapes nucleotide diversity, and proposes that its specialist host association contributes to a smaller effective population size and lower genetic variation than host generalist Caenorhabditis species with outbreeding reproductive modes. Expand
Molecular evolution and quantitative variation for chemosensory behaviour in the nematode genus Caenorhabditis
TLDR
The results suggest that C. remanei may be a more suitable subject for ecological and evolutionary genetic studies than C. elegans, and shows that the G‐protein ODR‐3 plays an important role in chemosensory avoidance behaviour and identifies orthologues of odr‐3 in C. briggsae and C.Remanei. Expand
Full-genome evolutionary histories of selfing, splitting, and selection in Caenorhabditis.
TLDR
Analysis of functional mutations indicates that genomic context, owing to selection that acts on long linkage blocks, is a more important driver of population variation than are the functional attributes of the individually encoded genes. Expand
Rapid sequence evolution of transcription factors controlling neuron differentiation in Caenorhabditis.

  • 1 October 2009
TLDR
TFs are illustrated that TFs are not as highly constrained as commonly thought and suggest that the role of divergence in developmental regulatory genes during the evolution of gene regulatory networks requires further attention. Expand
Evolutionary rates and centrality in the yeast gene regulatory network
TLDR
The position of a gene within the transcription network affects the rate of protein evolution such that more central transcription factors tend to evolve faster, and the effect of gene position is dependant on the function of the specific network under study. Expand
Duplication and divergence of fgf8 functions in teleost development and evolution.
TLDR
Phylogenetic analysis supports the view that the Fgf8/17/18-subfamily expanded during the ray-fin fish genome duplication, and direct comparison of stickleback and zebrafish embryonic expression patterns of f gf8 co-orthologs suggested lineage-specific independent subfunction partitioning and the acquisition or the loss of ortholog functions. Expand
Ephemeral-habitat colonization and neotropical species richness of Caenorhabditis nematodes
TLDR
It is hypothesized that a combination of rapid colonization, high ephemerality of resource patches, and species heterogeneity in degree of specialization on micro-habitats and life histories enables a dynamic co-existence of so many morphologically cryptic species of Caenorhabditis. Expand
