“…We modeled daily patterns of temperature for leaf litter and rock. We performed the modeling with generalized additive mixed models (GAMMs) in R (v 3.5) using the package mgcv (v 1.8.23) (Wood 2006) with time modeled using a thin plate regression spline and a Gamma error structure (to account for positive skew and improve normality of residuals). We estimated a separate smoothed term for each light microhabitat and specified day as a random effect (to account for uneven sampling and clustering of values among days due to weather).…”

“…From this information, we calculated mean walking speed, survey distance, and survey duration for each survey. We modeled apparent activity of H. clypeatus as a function of observer, time of day, and survey distance for each survey path using generalized additive models (Wood 2006). We specified a Poisson error structure for these count data, while controlling for any differences in the ability for observers to find spiders.…”

Temperature affects ectotherms in a variety of ways. These effects can be especially complex in sexual behaviors, as different sexes may be affected differently by temperature. We examined this in the jumping spider, Habronattus clypeatus. In this species, males court females using visual and vibratory signals. We tested whether key intersexual behaviors would change with temperature in similar, predictable ways across males and females. We first measured temperature and apparent activity of individuals across the day. We found that H. clypeatus are active across a wide range of temperatures (11-56°C) and are most active at times of day when temperature ranges from 13 to 46°C. Next, we performed mating experiments across behaviorally relevant temperatures. Females were more likely to allow males to progress to later stages of courtship and had higher mating rates at higher temperatures. Male visual and vibratory courtship behaviors generally became faster, higher-pitched, and lower in amplitude at higher temperatures. This relationship between temperature and signal aspects attained a roughly curvilinear shape, with an asymptote around 40°C. Intriguingly, mating rates in the lab were highest at temperatures potentially above those during peak spider activity in the field. Our results suggest that temperature's effects on behavior are complex and can affect males and females differently. This work emphasizes that understanding temperature effects on mating is critical to understanding sexual selection patterns particularly in species which use complex signals. Significance statementTemperature affects communication in most ectothermic species. Previous research has shown that temperature changes courter signals and chooser choice. However, this has never been investigated in species that use multimodal signals. We investigate how signals and choice change across temperatures in a desert-dwelling jumping spider. Using field temperature/activity modeling and a series of courtship experiments in the lab, we show that male signals and female choice change with temperature across biologically relevant ranges. Our results suggest that the temperatures at which mating is most likely occur at times of the day when animals are least active. These counterintuitive results highlight the importance of understanding how behavior in a controlled lab environment corresponds to natural field conditions as well as the importance of examining the effects of naturally occurring environmental variation on behavior.

“…The secondary eyes of salticids possess only one photoreceptor type and thus cannot discriminate colors (Yamashita & Tateda, ). Among the secondary eyes, the anterior lateral eyes (ALE) and posterior lateral eyes (PLE) are large, able to detect motion, and elicit an orienting response of the principal eyes toward the moving object (Duelli, ; Jakob et al, ; Spano, Long, & Jakob, ; Zurek & Nelson, , ; Zurek, Taylor, Evans, & Nelson, ). The posterior median eyes (PME) of most salticids (except for the non‐salticoids) are very small and positioned between ALE and PLE (Land, ; Maddison & Hedin, ).…”

Some animals have evolved task differentiation among their eyes. A particular example is spiders, where most species have eight eyes, of which two (the principal eyes) are used for object discrimination, whereas the other three pairs (secondary eyes) detect movement. In the ctenid spider Cupiennius salei, these two eye types correspond to two visual pathways in the brain. Each eye is associated with its own first-and second-order visual neuropil.The second-order neuropils of the principal eyes are connected to the arcuate body, whereas the second-order neuropils of the secondary eyes are linked to the mushroom body. We explored the principal-and secondary eye visual pathways of the jumping spider Marpissa muscosa, in which size and visual fields of the two eye types are considerably different. We found that the connectivity of the principal eye pathway is the same as in C. salei, while there are differences in the secondary eye pathways. In M. muscosa, all secondary eyes are connected to their own first-order visual neuropils. The first-order visual neuropils of the anterior lateral and posterior lateral eyes are connected with a secondorder visual neuropil each and an additional shared one (L2). In the posterior median eyes, the axons of their first-order visual neuropils project directly to the arcuate body, suggesting that the posterior median eyes do not detect movement. The L2 might function as an upstream integration center enabling faster movement decisions.

“…Some studies have demonstrated, however, that forward-facing anterior-lateral eyes (ALE) have high visual acuities (Eakin & Brandenburger 1971;Land 1985). They may play an important role in initial categorization of moving objects (Zurek & Nelson 2012) and initiation of appropriate responses, such as approach to prey and prey capture (Forster 1979;Zurek et al 2010).…”
