It is well known that oxidative stress is a major cause of DNA damage and telomere attrition.
Most endogenous reactive oxygen species (ROS) are produced in the mitochondria …

What explains preferences for elaborate ornamentation in animals? The default answer
remains that the prettiest males have the best genes. If mating signals predict good genes …

Sexual selection drives the evolution of some of the most exaggerated traits in nature.
Studies on sexual selection often focus on the size of these traits relative to body size, but …

This novel text provides a concise synthesis of how the interactions between mitochondrial
and nuclear genes have played a major role in sha** the ecology and evolution of …

Mitochondrial genes play an essential role in energy metabolism. Variation in the
mitochondrial DNA (mtDNA) sequence often exists within species, and this variation can …

Develo** animals are increasingly exposed to elevated temperatures as global
temperatures rise as a result of climate change. Vertebrates can be affected by elevated …

Song production across many songbird species is shaped by largely conserved sets of
constraints associated with song control, production, and perception. This chapter …

The novel brominated flame retardant, 1, 2-bis (2, 4, 6-tribromophenoxy) ethane (BTBPE),
has increasingly been detected in environmental and biota samples. However, limited …

Highlights•I explore two factors that can limit sexual trait elaboration: costs and constraints.•I
discuss operational strategies for identifying constraints on sexual traits.•I propose that costs …

Aging is associated with mitochondrial decline and reduced adenosine triphosphate (ATP)
production leading to cellular dysfunction, but this is improved by long-wavelength light …
