Light environment interacts with visual displays in a species-specific manner in multimodal signaling wolf spiders
<p>Light availability is highly variable, yet predictable, over various timescales and the light environment is expected to play an important role in the evolution of visual signals. Courtship displays within the wolf spider genus Schizocosa always involve the use of substrate borne vibrations, however, there is substantial variation between species in the use of visual displays. We assessed the impact of light intensity on the courtship of four species of Schizocosa that vary in their use of visual signals during courtship. To examine the effects of the light environment on mating success and courtship effort in each species, we ran behavioral trials at three light intensities (bright, dim and dark). We also examined each species' circadian activity patterns. We found multiple effects of the light environment and these varied between species. Circadian activity patterns also differed between species and sexes. Our results suggest that dim-light might favor more conspicuous visual displays, while less conspicuous displays might be favored in bright light conditions. Additionally, we found evidence for light-dependent changes in selection on male traits, illustrating that short-term changes in light intensity have the potential for strong effects on the dynamics of sexual selection.</p>
Data for: Traumatic mating causes strict monandry in a wolf spider
<p><span>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 <i>Pardosa pseudoannulata</i>. 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 reduced female's willingness to re-mate, we mimicked male pedipalp insertions by micro-injecting seminal fluids and/or causing trauma to female genital tracts and let them mate after the manipulations. Result of mating trials showed that seminal fluids have little impact to restrain female's mating willingness. However, once female genital tracts were wounded, its mating willingness would be greatly suppressed. In addition, impermeable amorphous mating plugs appeared in female genital tracts after mating. The mating plugs blocked female's genital tracts and completely prevented female from re-mating. We found that the components of mating plugs shared highly similar organic compounds and concentration percentage of free amino acids with female haemolymph, indicating that wounds caused by male traumatic mating lead to haemorrhages, which gradually turn into mating plugs. We thus provide evidence for strict female monandry being caused by male traumatic mating through two means together: genital trauma suppressed female's re-mating willingness and haemorrhage from the wounds formed impermeable mating plugs that completely prevented female from re-mating. </span></p>
