The segmented trapdoor spiders (Liphistiidae) are the sole surviving family of the suborder Mesothelae, which forms the sister lineage to all other living spiders. Liphistiids have retained a number of plesiomorphic traits and their present-day distribution is limited to East and Southeast Asia. Studying this group has the potential to shed light on the deep evolutionary history of spiders, but the phylogeny and divergence times of the family have not been resolved with confidence. We...

Sexual selection on jumping spider colour pattern: investigation with a new quantitative approach

Wei Zhou, Long Yu, Bernetta Z.W. Kwek, Jin Ge, Hua Zeng & Daiqin Li
How animals assess information encoded in individual colour patches have been extensively studied, yet the role of both individual colour patches and gross colour pattern (i.e. the combination of colour patches) remains understudied. We tested the functioning of both individual colour patches and gross colour pattern in sexual selection using the jumping spider Siler semiglaucus as a study system. We first quantified sexual dimorphism in S. semiglaucus in both individual patches and gross colour pattern...

Discoid decorations function to shield juvenile Argiope spiders from avian predator attacks

Bingjun Wang, Long Yu, Nina Ma, Zengtao Zhang, Qian Liu, Wenrui Fan, Yu Rong, Shichang Zhang & Daiqin Li
Decorating behavior is common in various animal taxa and serves a variety of functions from camouflage to communication. One predominant function cited for decoration is to avoid predators. Conspicuous, disc-like (discoid) silk decorations spun by orb-web Argiope juvenile spiders are hypothesized, among others, to defend spiders against visual predators by concealing spider outlines on the web, deflecting attacks, shielding them from view or masquerading as bird-droppings. However, the direct evidence is limited for a specific...

Data for: Traumatic mating causes strict monandry in a wolf spider

Shichang Zhang, Nina Ma, Deyong Gong, Xuemin Liu, Zeyuan Hua, Yao Zhao, Jie Liu, Xiaoguo Jiao & Yu Peng
In nature, most animal species are polygamous, and strict female monandry is rare. Though traumatic mating has been reported to postpone female re-mating, it rarely leads to strict female monandry. We demonstrate that traumatic mating causes strict female monandry in a wandering wolf spider Pardosa pseudoannulata. We showed direct evidence that male damaged the inner walls of the female genital tracts with the sharp embolus on its pedipalps during insemination. To confirm that the trauma...

Leaf δ13C and δ15N of aquatic macrophytes in the arid zone of northwestern China

Xusheng Gong, Zhongqiang Li, Zhiyan Xu, Qiutong Peng, Yuqing Tian, Yang Hu, Zhongqiang Li & Tao Hao
Raw data of species list, life form, carbon isotope ratio (δ13C) and nitrogen isotope ratio (δ15N) for all observations examined across the arid zone of northwestern China. Multi-annual mean precipitation (MAP, mm), multi-annual mean temperature (MAT, oC), potential evapotranspiration (PET, mm), sediment total carbon (STC), sediment total nitrogen (STN), longitude (Long.), latitude (Lat.) and altitude (Alt.) across the arid zone of northwestern China were also provided. We examined the spatial pattern of the leaf δ13C...
