Ecological speciation occurs with the adaptation of populations to different environments and concurrent evolution of reproductive isolation. Phenotypic plasticity might influence both ecological adaptation and reproductive traits. We examined environment-specific gene expression and male mating success in cactophilic Drosophila mojavensis using transcriptome sequencing. This species exhibits c...

Weissella oryzae was originally isolated from fermented rice grains. Here we report the draft genome sequence of the type strain of W. oryzae. This first report on the genomic sequence of this species may help identify the mechanisms underlying bacterial adaptation to the ecological niche of fermented rice grains.

Alicyclobacillus acidoterrestris is a spore-forming Gram-positive, thermo-acidophilic, nonpathogenic bacterium which contaminates commercial pasteurized fruit juices. The draft genome sequence for A. acidoterrestris strain ATCC 49025 is reported here, providing genetic data relevant to the successful adaptation and survival of this strain in its ecological niche.

The morphology of the vertebrate skeleton exhibits tremendous plasticity in evolution, allowing adaptation to a wide variety of ecological niches and lifestyles. Indjeian et al. now uncover how the cis regulation of a gene controls skeletal variation in fish and might have contributed to the evolution of bipedalism in humans.

Ecological indicators, historical land use, and invasive species detection in the lower Iowa River floodplain." MA has been approved by the Examining Committee for the thesis requirement for the Master of Arts degree in Geography at the May 2014 graduation.

The current study used ecological momentary assessment to test several tenets of the reserve capacity model (L.C. Gallo & K. A. Matthews, 2003). Women (N = 108) with varying socioeconomic status (SES) monitored positive and negative psychosocial experiences and emotions across 2 days. Measures of intrapsychic and social resources were aggregated to represent the reserve capacity available to ma...

We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention t...

What engenders biodiversity? Natural selection certainly adapts species to their ecological niches, but does it really create all of the new niches and new species to ll them? Consider: the most successful, complex, and numerous species on earth are composed of sexually-reproducing animals and owering plants. Both groups typically undergo a form of sexual selection through mate choice: animals ...
