Homotypic assortative mating is consistent across temporal scales in the spider Mecynogea lemniscata (Araneidae) Abstract Identifying patterns of size-assortative mating (SAM) indicates the direction of genetic changes in a population. A reliable method for estimating it in a population is to measure mate assortments within and between breeding seasons¸ as well as describing size variation of males and females between temporal scales to avoid Simpson’s paradox. We assessed sexual size dimorphism, the effects of ontogeny, size differences within each sex, the consistency of SAM within and between seasons, and male mate choice in the spider  Mecynogea lemniscata . We collected mating pairs in a  Eucalyptus  plantation across two breeding seasons and in four periods of the second season. We measured body mass and carapace width of spiders. Males matured earlier than females and guarded subadult partners. Although adults were larger and heavier than subadults, ontogeny did no...

The genome sequence of an orb-weaver spider, Araneus angulatus Clerck, 1757 (Araneae: Araneidae)

Abstract

We present a genome assembly from an individual female Araneus angulatus (orb-weaver spider; Arthropoda; Arachnida; Araneae; Araneidae). The assembly contains two haplotypes with total lengths of 2 980.91 megabases and 2 941.08 megabases. Most of haplotype 1 (94.74%) is scaffolded into 28 chromosomal pseudomolecules. Haplotype 2 was assembled to scaffold level. The mitochondrial genome has also been assembled, with a length of 14.53 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.
