Insertion of a chimeric retrotransposon sequence in mouse Axin1 locus causes metastable kinky tail phenotype
Transposable elements (TEs) make up >50% of the human genome, and the majority of retrotransposon insertions are truncated and many are located in introns. However, the effects of retrotransposition on the host genes remain ...
Thermal Benefits From White Variegation of Silybum marianum Leaves
Leaves of the spiny winter annual Silybum marianum express white patches (variegation) that can cover significant surface areas, the outcome of air spaces formed between the epidermis and the green chlorenchyma. We asked: ...
Interaction Diversity Maintains Resiliency in a Frequently Disturbed Ecosystem
Frequently disturbed ecosystems are characterized by resilience to ecological disturbances. Longleaf pine ecosystems are not only resilient to frequent fire disturbance, but this feature sustains biodiversity. We examined ...
Fully automated sequence alignment methods are comparable to, and much faster than, traditional methods in large data sets: an example with hepatitis B virus
Aligning sequences for phylogenetic analysis (multiple sequence alignment
Seed predation increases from the Arctic to the Equator and from high to low elevations
Species interactions have long been predicted to increase in intensity toward the tropics and low elevations because of gradients in climate, productivity, or biodiversity. Despite their importance for understanding global ...
Spatial Phylogenetics of Florida Vascular Plants: The Effects of Calibration and Uncertainty on Diversity Estimates
Recent availability of biodiversity data resources has enabled an unprecedented ability to estimate phylogenetically based biodiversity metrics over broad scales. Such approaches elucidate ecological and evolutionary ...
Impacts of growing-season climate on tree growth and post-fire regeneration in ponderosa pine and Douglas-fir forests
We studied the impacts of climate variability on low-elevation forests in the U.S. northern Rocky Mountains by quantifying how post-fire tree regeneration and radial growth varied with growing-season climate. We reconstructed ...
Loss of Prune in Circadian Cells Decreases the Amplitude of the Circadian Locomotor Rhythm in Drosophila
The circadian system, which has a period of about 24 h, is import for organismal health and fitness. The molecular circadian clock consists of feedback loops involving both transcription and translation, and proper function ...
Independent Scientific Review under the Endangered Species Act
The directive from Congress in the Endangered Species Act obliging the US Fish and Wildlife Service and National Marine Fisheries Service along with other federal agencies to use the best available scientific information ...
What lies beneath? Molecular evolution during the radiation of caecilian amphibians
Evolution leaves an imprint in species through genetic change. At the molecular level, evolutionary changes can be explored by studying ratios of nucleotide substitutions. The interplay among molecular evolution, derived ...
