Effect of laboratory heat stress on mortality and web mass of the common house spider, Parasteatoda tepidariorum (Koch 1841) (Araneae: Theridiidae) [PDF]
, 2020 We determined the effects of chronic heat stress on web construction of Parasteatoda tepidariorum (Araneae: Theridiidae) by measuring the survival and web mass of specimens after a 48-h period within a temperature chamber at 21, 30, 35, 40, or 50°C.

Atmospheric Circulation on Black Widow Companions [PDF]
, 2020 We present a model for atmospheric wind circulation in binary millisecond pulsar (MSP) companions, showing how the optical light curve (LC) and radial velocities (RV) are sensitive to the wind flow, causing LC orbital phase shifts and asymmetries, as observed for several `spider' MSP. Velocity widths of spectral lines offer additional opportunities for

X-ray Through Very-High-Energy Intrabinary Shock Emission from Black Widows and Redbacks [PDF]
, 2020 Black widow and redback systems are compact binaries in which a millisecond pulsar heats and may even ablate its low-mass companion by its intense wind of relativistic particles and radiation. In such systems, an intrabinary shock can form as a site of particle acceleration and associated non-thermal emission.

Change of rotation measure during eclipse of a black widow PSR J2051$-$0827 [PDF]
arXiv, 2023 Black widows are millisecond pulsars ablating their companions. The material blown from the companion blocks the radio emission, resulting in radio eclipses. The properties of the eclipse medium are poorly understood. Here, we present direct evidence of the existence of magnetic fields in the eclipse medium of the black widow PSR J2051$-$0827 using ...

Nephila spider male aggregation: preference for optimal female size and web clustering
Integrative Zoology, EarlyView.Our snapshot census of Nephila spider males in female webs in Singapore reveals a female‐biased operational sex ratio. Our findings support two hypotheses that explain the uneven distribution of males among female webs: the optimal female size hypothesis and the web clustering hypothesis.

Which treatments relieve painful muscle spasms from a black widow spider bite? [PDF]
, 2012 Opioids relieve pain and benzodiazepines ease muscle spasms in most patients with latrodectism--widespread, sustained spasms--resulting from envenomation by a black widow spider (strength of recommendation [SOR]: C, case series).
