Spider genomes provide insight into composition and evolution of venom and silk
Spiders are ecologically important predators with complex venom and extraordinarily tough silk that enables capture of large prey. Here we present the assembled genome of the social velvet spider andExpand
The house spider genome reveals an ancient whole-genome duplication during arachnid evolution
BackgroundThe duplication of genes can occur through various mechanisms and is thought to make a major contribution to the evolutionary diversification of organisms. There is increasing evidence forExpand
Endosymbiont Dominated Bacterial Communities in a Dwarf Spider
The microbial community of spiders is little known, with previous studies focussing primarily on the medical importance of spiders as vectors of pathogenic bacteria and on the screening of knownExpand
Spiders do not escape reproductive manipulations by Wolbachia
BackgroundMaternally inherited bacteria that reside obligatorily or facultatively in arthropods can increase their prevalence in the population by altering their hosts' reproduction. SuchExpand
Comparative genomic study of arachnid immune systems indicates loss of beta‐1,3‐glucanase‐related proteins and the immune deficiency pathway
Analyses of arthropod genomes have shown that the genes in the different innate humoral immune responses are conserved. These genes encode proteins that are involved in immune signalling pathwaysExpand
Male spiders control offspring sex ratio through greater production of female-determining sperm
Sex allocation theory predicts that when sons and daughters have different reproductive values, parents should adjust offspring sex ratio towards the sex with the higher fitness return. Haplo-diploidExpand
The golden age of arthropods: ancient mechanisms of colour production in body scales
Insect colour is extremely diverse and produced by a large number of pigmentary and nanostructural mechanisms. Considerable research has been dedicated to these optical mechanisms, with most of itExpand
Evidence for Faster X Chromosome Evolution in Spiders
Abstract In species with chromosomal sex determination, X chromosomes are predicted to evolve faster than autosomes because of positive selection on recessive alleles or weak purifying selection. WeExpand
Corrigendum: Spider genomes provide insight into composition and evolution of venom and silk
Nature Communications 5: Article number: 3765 (2014); Published: 6 May 2014; Updated: 6 August 2014. The original version of the Supplementary Information attached to this Article contained an errorExpand
Benefits of Group Living Include Increased Feeding Efficiency and Lower Mass Loss during Desiccation in the Social and Inbreeding Spider Stegodyphus dumicola
Group living carries a price: it inherently entails increased competition for resources and reproduction, and may also be associated with mating among relatives, which carries costs of inbreeding.Expand
