Traffic noise leads to cardiac stress reactions in two, urban-tolerant, <em>Trichonephila</em> spiders, but in different ways

For this study, we measured heart rate elevations in two orb-weaving Trichonephila spiders in the United States, the non-native jorō spider (Trichonephila clavata) and the golden silk spider (Trichonephila clavipes). Mature females were captured along roads at natural areas with either prior exposure to loud noise with high daily traffic patterns or quiet sites with low daily traffic patterns. In the laboratory, each female was placed in an enclosure that enabled web-building. Enclosures were built from a 60 cm x 60 cm x 6 cm wooden frame with clear plastic attached to each side. For our experiments, we broadcast a simulated pink noise signal&nbsp;(lowpass 1/f, 0.20 Hz frequency cut off, 44.1 kHz sample rate) at captive spiders and monitored their heart rate via contractions of the dorsal vessel, which we monitored remotely by high-magnification video.&nbsp;We quantified spider heart rates from the recorded videos by counting the number of heart beats per minute prior to noise exposure ..., , # Data from: Traffic noise leads to cardiac stress reactions in two, urban-tolerant, *Trichonephila* spiders, but in different ways Dataset DOI: [10.5061/dryad.pzgmsbd30](https://doi.org/10.5061/dryad.pzgmsbd30) ## Description of the data and file structure For both files: mass (g), heart rate (beats per minute), change (change in heart rate measured as beats per minute). Species include *Trichonephila clavata* and *Trichonephila clavipes.* Location describes the location of the collection. Habitat references whether the collection location was quiet or loud. Each individual spider received a unique identifier (spiderID). ### Files and variables #### File: Heart_rate_change.xlsx **Description:** Change in heart rate from baseline to maximum. ##### Variables * spiderID (unique individual ID), * Species (*Trichonephila clavata* or *Trichonephila clavipes*), * Location (collection location), * Habitat (quiet or loud), * mass (g), * change (beats per minute), NA means \"not a..., ,
