Biologists have long appreciated the critical role that energy turnover plays in understanding
variation in performance and fitness among individuals. Whole-organism metabolic studies …

Mitochondria are key to energy conversion in virtually all eukaryotes. Intriguingly, despite
billions of years of evolution inside the eukaryote, mitochondria have retained their own …

Mitochondria, a nearly ubiquitous feature of eukaryotes, are derived from an ancient
symbiosis. Despite billions of years of cooperative coevolution—in what is arguably the most …

Oxidative phosphorylation, the primary source of cellular energy in eukaryotes, requires
gene products encoded in both the nuclear and mitochondrial genomes. As a result …

Aerobic metabolism in eukaryotic cells requires extensive interactions between products of
the nuclear and mitochondrial genomes. Rapid evolution of the mitochondrial genome …

Mitochondrial (mt) and nuclear-encoded proteins are integrated in aerobic respiration,
requiring co-functionality among gene products from fundamentally different genomes …

Natural selection acts on the phenotype. Therefore, many mistakenly expect to observe its
signatures only in the organism, while overlooking its impact on tissues, cells and …

Accurately determining avian species limits has been a challenge and a work in progress for
most of a century. It is a fascinating but difficult problem. Under the biological species …

Mitochondria are organelles that produce cellular energy in the form of ATP through
oxidative phosphorylation, and this primary function is conserved among many taxa …

Given the availability of genomic data to identify separately evolving groups of organisms,
many researchers establish species limits based on assessments of the extent of gene flow …
