Clade Age and Diversification Rate Variation Explain Disparity in Species Richness among Water Scavenger Beetle (Hydrophilidae) Lineages
(Public Library of Science, 2014-06-02)Explaining the disparity of species richness across the tree of life is one of the great challenges in evolutionary biology. Some lineages are exceptionally species rich, while others are relatively species poor. One ... -
Inferring Gene Family Histories in Yeast Identifies Lineage Specific Expansions
(Public Library of Science, 2014-06-12)The complement of genes found in the genome is a balance between gene gain and gene loss. Knowledge of the specific genes that are gained and lost over evolutionary time allows an understanding of the evolution of biological ... -
Extreme adaptations for aquatic ectoparasitism in a Jurassic fly larva
(eLife Sciences Publications, Ltd, 2014-06-24)The reconstruction of ancient insect ectoparasitism is challenging, mostly because of the extreme scarcity of fossils with obvious ectoparasitic features such as sucking-piercing mouthparts and specialized attachment organs. ... -
The Use of Ecological Niche Modeling to Infer Potential Risk Areas of Snakebite in the Mexican State of Veracruz
(Public Library of Science, 2014-06-24)Background Many authors have claimed that snakebite risk is associated with human population density, human activities, and snake behavior. Here we analyzed whether environmental suitability of vipers can be used as an ... -
