Stronger evidence for relaxed selection than adaptive evolution in high-elevation animal mtDNA

E. N. K. Iverson, A. Criswell, J. C. Havird

The paper tests whether high-elevation species show adaptive evolution or relaxed selection in mtDNA, finding relaxed selection is more likely due to smaller ranges and population size.

Mitonuclear sex determination? Empirical evidence frombivalves

C. H. Smith, R. Mejia-Trujillo, S. H. Breton, B. J. Pinto, M. Kirkpatrick, J. C. Havird

This study investigates the role of mitochondrial and nuclear genes in sex determination in bivalves, finding that male mtDNA sncRNAs inhibit female development while nuclear factors remain inconclusive.

A tale of two paths: The evolution of mitochondrial recombination in bivalves with doubly uniparental inheritance

C. H. Smith, B. J. Pinto, M. Kirkpatrick, D. M. Hillis, J. M. Pfeiffer, J. C. Havird

This study investigates mitochondrial recombination in bivalves with doubly uniparental inheritance, finding evidence for a single origin of male mitochondrial DNA and ongoing recombination in some species.

Disentangling positive vs. relaxed selection in animal mitochondrial genomes

K. D. Zwonitzer, E. N. K. Iverson, J. J. Sterling, R. J. Weaver, B. A. Maclaine, J. C. Havird

The paper reevaluates seven case studies of elevated dN/dS ratios in animal mtDNA, finding that elevated ratios are often not caused by the predicted selection mechanisms and sometimes support the opposite.

A Lethal Genetic Incompatibility between Naturally Hybridizing Species in Mitochondrial Complex I

B. M. Moran, C. Y. Payne, D. L. Powell, E. N. Iverson, A. E. Donny, S. M. Banerjee, Q. K. Langdon, T. R. Gunn, R. A. Rodriguez-Soto, A. Madero, J. J. Baczenas, K. M. Kleczko, F. Liu, R. Matney, K. Singhal, , M. Schumer

The paper identifies a lethal mitonuclear incompatibility in swordtail fish hybrids involving three Complex I genes, showing non-additive genetic effects and inter-species transfer of incompatibility.

Temperature-dependence of metabolic rate in tropical and temperate aquatic insects: support for the Climate Variability Hypothesis in mayflies but not stoneflies.

A. A. Shah, H. A. Woods, J. C. Havird, E. C. Encalada, A. S. Flecker, W. C. Funk, J. M. Guayasamin, B. K. Kondratieff, N. L. Poff, S. A. Thomas, K. R. Zamudio, C. K. Ghalambor

This study examines the thermal sensitivity of metabolic rates in tropical and temperate aquatic insects, finding greater sensitivity in tropical mayflies but not stoneflies.

Assessing mitochondrial function in angiosperms with highly divergent mitochondrial genomes

J. C. Havird, G. R. Noe, L. Link, A. Torres, D. C. Logan, D. B. Sloan, A. J. Chicco

The paper develops a protocol to assess mitochondrial function in Silene species with rapidly evolving and fragmented mt genomes, finding similar respiratory flux contributions to previously studied angiosperms.
