Data from: Genomic changes following the reversal of a Y chromosome to an autosome in Drosophila pseudoobscura

Ching-Ho Chang & Amanda M. Larracuente
Robertsonian translocations resulting in fusions between sex chromosomes and autosomes shape karyotype evolution by creating new sex chromosomes from autosomes. These translocations can also reverse sex chromosomes back into autosomes, which is especially intriguing given the dramatic differences between autosomes and sex chromosomes. To study the genomic events following a Y chromosome reversal, we investigated an autosome-Y translocation in Drosophila pseudoobscura. The ancestral Y chromosome fused to a small autosome (the dot chromosome) approximately 10–15...

Data from: A metacognitive illusion in monkeys

Stephen Ferrigno, Nate Kornell & Jessica F. Cantlon
Like humans, monkeys can make accurate judgements about their own memory by reporting their confidence during cognitive tasks. Some have suggested that animals use associative learning to make accurate confidence judgements, while others have suggested animals directly access and estimate the strength of their memories. Here we test a third, non-exclusive possibility: perhaps monkeys, like humans, base metacognitive inferences on heuristic cues. Humans are known to use cues like perceptual fluency (e.g. how easy something...

Data from: Single molecule sequencing resolves the detailed structure of complex satellite DNA loci in Drosophila melanogaster

Daniel Emerson Khost, Danna G. Eickbush & Amanda M. Larracuente
Highly-repetitive satellite DNA (satDNA) repeats are found in most eukaryotic genomes. SatDNAs are rapidly evolving and have roles in genome stability and chromosome segregation. Their repetitive nature poses a challenge for genome assembly and makes progress on the detailed study of satDNA structure difficult. Here we use single-molecule sequencing long reads from Pacific Biosciences (PacBio) to determine the detailed structure of all major autosomal complex satDNA loci in Drosophila melanogaster, with a particular focus on...

Data from: Correlates of decisional dynamics in the dorsal anterior cingulate cortex

Habiba Azab & Benjamin Y. Hayden
We hypothesized that during binary economic choice, decision makers use the first option they attend as a default to which they compare the second. To test this idea, we recorded activity of neurons in the dorsal anterior cingulate cortex (dACC) of macaques choosing between gambles presented asynchronously. We find that ensemble encoding of the value of the first offer includes both choice-dependent and choice-independent aspects, as if reflecting a partial decision. That is, its responses...

Data from: Rediscovery of the enigmatic fungus-farming ant \"Mycetosoritis\" asper Mayr (Hymenoptera: Formicidae): Implications for taxonomy, phylogeny, and the evolution of agriculture in ants

Jeffrey Sosa-Calvo, Ana Ješovnik, Heraldo L. Vasconcelos, , Ted R. Schultz & Mauricio Bacci
We report the rediscovery of the exceedingly rarely collected and enigmatic fungus-farming ant species Mycetosoritis asper. Since the description of the type specimen in 1887, only four additional specimens are known to have been added to the world's insect collections. Its biology is entirely unknown and its phylogenetic position within the fungus-farming ants has remained puzzling due to its aberrant morphology. In 2014 we excavated and collected twenty-one colonies of M. asper in the Floresta...

Data from: Genotype specificity among hosts, pathogens, and beneficial microbes influences the strength of symbiont mediated protection

Benjamin J. Parker, Jan Hrcek, Ailsa H.C. McLean, H. Charles J. Godfray & Ailsa H. C. McLean
The microbial symbionts of eukaryotes influence disease resistance in many host-parasite systems. Symbionts show substantial variation in both genotype and phenotype, but it is unclear how natural selection maintains this variation. It is also unknown whether variable symbiont genotypes show specificity with the genotypes of hosts or parasites in natural populations. Genotype by genotype interactions are a necessary condition for coevolution between interacting species. Uncovering the patterns of genetic specificity among hosts, symbionts, and parasites...
