Three-Dimensionally Preserved Integument Reveals Hydrodynamic Adaptations in the Extinct Marine Lizard Ectenosaurus (Reptilia, Mosasauridae)
Download2011
Lindgren, Johan, Everhart, Michael J., Caldwell, Michael W.
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...

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...

Li, R., Zheng, W., Durbin, R., Liu, T., Bolund, L., Dehal, P., Coin, L.J., Coghlan, A., Osmotherly, L., Heriche, J.K., Ruan, J., Li, H., Wang, J., Wong, G., Zhang, Z.
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,...

Sponges link the microbial loop with benthic communities by feeding on bacteria. Glass sponge reefs on the continental shelf of western Canada have extremely high grazing rates, consuming seven times more particulate carbon than can be supplied by vertical flux alone. Unlike many sponges, the...

Understanding the evolution of the membrane trafficking system in diverse eukaryotes through comparative genomics and transcriptomics
DownloadSpring 2018
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...

Unequal recombination and evolution of the mating-type (MAT) loci in the pathogenic fungus Grosmannia clavigera and relatives. G3: Genes, Genomes, Genetics
Download2013-01-01
Hamelin, Richard C., Tsui, Clement K.M., Bohlmann, Jörg, DiGuistini, Scott, Dhillon, Braham, Feau, Nicolas, Wang, Ye
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....

Uptake of waterborne selenite, and its toxic effects, in the water flea (Daphnia magna), Westslope cutthroat trout (Oncorhynchus clarkii lewisi) and rainbow trout (Oncorhynchus mykiss)
DownloadSpring 2024
Selenium is an essential element, playing an important role in many physiological processes. However, it possesses a narrow margin between essentiality and toxicity. In aquatic systems, selenium is increasingly identified as a trace element of major concern with levels exceeding regulatory...

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...

Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups including...
