Look Who\u27s Talking: Differences in Rates of Interruptions and Proportion of Time Used by Male and Female U.S. Courts of Appeals Judges

During oral arguments, attorneys are given the chance to elaborate on their written briefs and answer questions from the judges deciding the case. Studying oral arguments can be a window into the power dynamics between judges and attorneys, and can shed light onto how factors like gender may affect judicial decision-making. While a growing body of research has examined gender dynamics in oral arguments in the United States Supreme Court, no existing studies have examined whether these findings hold up in the U.S. Court of Appeals, the second highest courts in the country. We collected data on two years of oral arguments from the 4th Circuit in order to test theories about gender and speech patterns, including interruptions and verbosity

Molecular taxonomic analysis of the plant associations of adult pollen beetles (Nitidulidae: Meligethinae), and the population structure of Brassicogethes aeneus

Pollen beetles (Nitidulidae: Meligethinae) are among the most abundant flower-visiting insects in Europe. While some species damage millions of hectares of crops annually, the biology of many species is little known. We assessed the utility of a 797 base pair fragment of the cytochrome oxidase 1 gene to resolve molecular operational taxonomic units (MOTUs) in 750 adult pollen beetles sampled from flowers of 63 plant species sampled across the UK and continental Europe. We used the same locus to analyse region-scale patterns in population structure and demography in an economically important pest, Brassicogethes aeneus. We identified 44 Meligethinae at ∼2% divergence, 35 of which contained published sequences. A few specimens could not be identified because the MOTUs containing them included published sequences for multiple Linnaean species, suggesting either retention of ancestral haplotype polymorphism or identification errors in published sequences. Over 90% of UK specimens were identifiable as B. aeneus. Plant associations of adult B. aeneus were found to be far wider taxonomically than for their larvae. UK B. aeneus populations showed contrasting affiliations between the north (most similar to Scandinavia and the Baltic) and south (most similar to western continental Europe), with strong signatures of population growth in the south
