Sounds of senescence: Male swamp sparrows respond less aggressively to the song of older individuals

Matthew Zipple, Susan Peters, William Searcy & Stephen Nowicki
Age-related changes in assessment signals occur in a diverse array of animals, including humans. Age-related decline in vocal quality in humans is known to affect perceived attractiveness by potential mates and voters, but whether such changes have functional implications for non-human animals is poorly understood. Most studies of age-related change in animal signals focus on increases in signal quality that occur soon after the age of first breeding (“delayed maturation”), but a few have shown...

Data from: Diving behavior of Cuvier's beaked whales (Ziphius cavirostris) off Cape Hatteras, North Carolina

Cuvier’s beaked whales exhibit exceptionally long and deep foraging dives. The species is relatively little studied due to their deep-water, offshore distribution and limited time spent at the surface. We used LIMPET satellite tags to study the diving behavior of Cuvier's beaked whales off Cape Hatteras, North Carolina from 2014 to 2016. We deployed 11 tags, recording 3,242 hours of behavior data, encompassing 5,926 dives. Dive types were highly bimodal; deep dives (>800m, n=1,408) had...

Data from: Antagonistic selection and pleiotropy constrain the evolution of plant chemical defenses

Rose A Keith & Thomas Mitchell-Olds
When pleiotropy is present, genetic correlations may constrain the evolution of ecologically important traits. We used a quantitative genetics approach to investigate constraints on the evolution of secondary metabolites in a wild mustard, Boechera stricta. Much of the genetic variation in chemical composition of glucosinolates in B. stricta is controlled by a single locus, BCMA1/3. In a large-scale common garden experiment under natural conditions, we quantified fitness and glucosinolate profile in two leaf types and...

Data from: Uncovering the genomic signature of ancient introgression between white oak lineages (Quercus)

Andrew A. Crowl, Paul S. Manos, John D. McVay, Alan R. Lemmon, Emily Moriarty Lemmon & Andrew L. Hipp
• Botanists have long recognized interspecific gene flow as a common occurrence within white oaks (Quercus section Quercus). Historical allele exchange, however, has not been fully characterized, and the complex genomic signals resulting from the combination of vertical and horizontal gene transmission may confound phylogenetic inference and obscure our ability to accurately infer the deep evolutionary history of oaks. • Using anchored enrichment, we obtained a phylogenomic dataset consisting of hundreds of single-copy nuclear loci....

Data from: Genes, geology, and germs: gut microbiota across a primate hybrid zone are explained by site soil properties, not host species

Laura E. Grieneisen, Marie J. E. Charpentier, Susan C. Alberts, Ran Blekhman, Gideon Bradburd, Jenny Tung & Elizabeth A. Archie
Gut microbiota in geographically isolated host populations are often distinct. These differences have been attributed to between-population differences in host behaviors, environments, genetics, and geographic distance. However, which factors are most important remains unknown. Here we fill this gap for baboons by leveraging information on 13 environmental variables from 14 baboon populations spanning a natural hybrid zone. Sampling across a hybrid zone allowed us to additionally test whether phylosymbiosis (codiversification between hosts and their microbiota)...

Data from: A mitochondrial progesterone receptor increases cardiac beta-oxidation and remodeling

Qunsheng Dai, Creighton E Likes, Anthony L Luz, Lan Mao, Jason S Yeh, Zhengzheng Wei, Maragatha Kuchibhatla, Olga R Ilkayeva, Timothy R Koves & Thomas M Price
Progesterone is primarily a pregnancy related hormone, produced in substantial quantities after ovulation and during gestation. Traditionally known to function via nuclear receptors for transcriptional regulation there is also evidence of non-nuclear action. A previously identified mitochondrial progesterone receptor (PR-M) increases cellular respiration in cell models. In these studies, we demonstrated that expression of PR-M in rat H9c2 cardiomyocytes resulted in a ligand-dependent increase in oxidative cellular respiration and beta-oxidation. Cardiac expression in a TET-On...
