Introduction: The core notion of Godfrey Smith’s account is that of a ‘Darwinian population’, which is “a population—a collection of particular things—that has the capacity to undergo evolution by natural selection” (page 6). A ‘Darwinian individual’ is a member of such an evolving population....
Smallpox was eradicated using vaccinia viruses (VACV) as vaccines, including Dryvax, a calf-lymph vaccine derived from the New York City Board of Health (NYCBH) strain, and TianTan, a chicken egg cultured vaccine used exclusively in China. To take advantage of the next generation sequencing...
Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, GeneticsDownload
Sexual reproduction in fungi is regulated by the mating-type (MAT) locus where recombination is suppressed. We investigated the evolution of MAT loci in eight fungal species belonging to Grosmannia and Ophiostoma (Sordariomycetes, Ascomycota) that include conifer pathogens and beetle symbionts....
Understanding the evolution of the membrane trafficking system in diverse eukaryotes through comparative genomics and transcriptomicsDownload
Single-celled organisms represent the majority of eukaryotic diversity. Recent advances in sequencing technologies have been critical for understanding the evolutionary biology and cell biology of microbial eukaryotes. Comparative genomic analyses have shown that many genes that underlie...
TreeFam is a database of phylogenetic trees of gene families found in animals. It aims to develop a curated resource that presents the accurate evolutionary history of all animal gene families, as well as reliable ortholog and paralog assignments. Curated families are being added progressively,...
Transferrin is an evolutionary conserved protein that in addition to having a critical role in iron transport also has been shown to have a crucial role in host defence. Transferrin has been shown to sequester iron from invading pathogens, act directly against microbial pathogens, and is an...
Three-Dimensionally Preserved Integument Reveals Hydrodynamic Adaptations in the Extinct Marine Lizard Ectenosaurus (Reptilia, Mosasauridae)Download
The physical properties of water and the environment it presents to its inhabitants provide stringent constraints and selection pressures affecting aquatic adaptation and evolution. Mosasaurs (a group of secondarily aquatic reptiles that occupied a broad array of predatory niches in the...
The probable association of feather mites of the genus Ingrassia (Analgoidea: Xolalgidae) with the blue penguin Eudyptula minor (Aves: Sphenisciformes) in Australia.Download
A new feather mite species, Ingrassia eudyptula n. sp. (Xolalgidae: Ingrassiinae), is described from the blue penguin Eudyptula minor (J. B. Forster, 1781) in Australia. This is the first description of a feather mite species from representatives of the avian order Sphenisciformes, which had...
The mitochondrial genome of the hexactinellid sponge Aphrocallistes vastus: Evidence for programmed translational frameshiftingDownload
Background: Mitochondrial genomes (mtDNA) of numerous sponges have been sequenced as part of an ongoing effort to resolve the class-level phylogeny of the Porifera, as well as to place the various lower metazoan groups on the animal-kingdom tree. Most recently, the partial mtDNA of two glass...
The Role of Hydropteris pinnata gen. et. sp. nov. In Reconstructing the cladistics of Heterosporous Ferns.Download
Large segments of intact plants that represent a heterosporous fern have been discovered within an aquatic plant community from the Late Cretaceous St. Mary River Formation near Cardston in southern Alberta, Canada. Branching rhizomes of Hydropteris pinnata gen. et sp. nov. are 1-2 mm wide. They...
