Data from: Phylogeny suggests non-directional and isometric evolution of sexual size dimorphism in argiopine spiders

Ren-Chung Cheng & Matjaž Kuntner
Sexual dimorphism describes substantial differences between male and female phenotypes. In spiders, sexual dimorphism research almost exclusively focuses on size, and recent studies have recovered steady evolutionary size increases in females, and independent evolutionary size changes in males. Their discordance is due to negative allometric size patterns caused by different selection pressures on male and female size (converse Rensch's rule). Here, we investigated macroevolutionary patterns of sexual size dimorphism (SSD) in Argiopinae, a global lineage...

Data from: DNA barcoding gap: reliable species identification over morphological and geographical scales

Klemen Čandek & Matjaž Kuntner
The philosophical basis, and utility of DNA barcoding has been a subject of numerous debates. While most literature embraces it, some studies continue to question its use in dipterans, butterflies, and marine gastropods. Here, we explore the utility of DNA barcoding in identifying spider species that vary in taxonomic affiliation, morphological diagnosibility and geographic distribution. Our first test searched for a “barcoding gap” by comparing intra- and interspecific means, medians and overlap in more than...
