Lizard Dewlap Color and Malaria Infection: Testing the Hamilton-Zuk Hypothesis

Diversity, 2023
The Hamilton-Zuk hypothesis indicates that parasites may have a negative effect on the appearance of sexual traits within an infected individual. Anolis sagrei, or brown anoles, are small invasive lizards common throughout Florida and many other areas ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Environmental Gradients in Lizard Colouration

Ecology and Evolution
Environmental pressures shape animal colouration, facilitating adaptation to local conditions. However, the extent to which climatic gradients drive colour variation in a species across its distributional range remains unclear.

The sky brightness and transparency in i-band at Dome A, Antarctica

, 2011
The i-band observing conditions at Dome A on the Antarctic plateau have been investigated using data acquired during 2008 with the Chinese Small Telescope ARray. The sky brightness, variations in atmospheric transparency, cloud cover, and the presence of

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

The nature of solar brightness variations [PDF]

, 2017
Determining the sources of solar brightness variations1,2, often referred to as solar noise3, is important because solar noise limits the detection of solar oscillations3, is one of the drivers of the Earth’s climate system4,5 and is a prototype of ...

The Effects of Washing between Hydrogen Peroxide Bleaching Stages on Brightness Reversion of a Spruce High-Yield Pulp [PDF]

, 1996
The final brightness of a bleached high-yield pulp paper product is a very important factor in determining the quality of the pulp and the product. If the brightness of this product tends to revert in time, then the quality of the product could be viewed

Normal Globular Cluster Systems in Massive Low Surface Brightness Galaxies [PDF]

, 2007
We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wide range of central surface brightness values, including two intermediate ...
