Urban heat island conditions experienced by the Western black widow spider (Latrodectus hesperus): extreme heat slows development but results in behavioral accommodations
Herein lies data on urban h eat island conditions for black widow spiders across the CAP study area. It also includes data on the development speed and behavioral responses of spiders reared in the lab at these UHI temperatures. The urban heat island (UHI) effect describes the capture of heat by built structures (e.g. asphalt), resulting in elevated urban temperatures. The UHI is a well-studied phenomenon, but only a handful of studies have investigated trait-based shifts resulting from the UHI, and even fewer have attempted to quantify the magnitude of the UHI experienced at the microclimate scale. Here, using a common urban exploiter, the Western black widow spider (Latrodectus hesperus), we show that the UHI experienced by spiders in July in their urban Phoenix, AZ refuges is 6 degrees C hotter (33 degrees C) than conditions in the refuges of spiders from Sonoran Desert habitat outside of Phoenix-area development (27 degrees C). We then use this field microclimate UHI estimate to compare the development speed, mass gain and mortality of replicate siblings from 36 urban lineages reared at temperatures that reflect urban and desert habitats. We show that extreme heat is slowing the growth of spiderlings and increasing mortality. In contrast, we show that development of male spiders to their penultimate moult is accelerated by 2 weeks. Lastly, in terms of behavioral shifts, UHI temperatures caused late-stage juvenile male spiders to heighten their foraging voracity and late-stage juvenile female spiders to curtail their web-building behavior.
Experiencing short heat waves early in development changes thermal responsiveness of turtle embryos to later heat waves
<p><span>Although physiological responses to the thermal environment are most frequently investigated using constant temperatures, the incorporation of thermal variability can allow for a more accurate prediction of how thermally sensitive species respond to a rapidly changing climate. In species with temperature-dependent sex determination (TSD), developmental responses to incubation temperature are mediated by several genes involved in gonadal differentiation. <em>Kdm6b</em> and <em>Dmrt1</em> respond to cool incubation temperatures and are associated with testis development, while <em>Foxl2</em> and <em>Cyp19A1</em> respond to warm incubation temperatures and are associated with ovary development. Using fluctuating incubation temperatures, we designed two studies, one investigating how conflicting thermal cues affect the timing of commitment to gonadal development, and another investigating the rapid molecular responses to conflicting thermal cues in the red-eared slider turtle (<em>Trachemys</em> <em>scripta</em>). Using gene expression as a proxy of timing of commitment to gonadal fate, results from the first study show that exposure to high amounts of conflicting thermal cues during development delays commitment to gonadal fate. Results from the second study show that <em>Kdm6b</em> splice variants exhibit differential responses to early heat wave exposure, but rapidly (within 2 days) recover to pre-exposure levels after the heat wave. Despite changes in the expression of <em>Kdm6b</em> splice variants, there was no effect on <em>Dmrt1</em> expression. Collectively, these findings demonstrate how short exposures to heat early in development can change how embryos respond to heat later in development.</span></p>

Data from: Oxidative stress experienced during early development influences the offspring phenotype
<p>Oxidative stress (OS) experienced early in life can affect an individual's phenotype. However, its consequences for the next generation remain largely unexplored. We manipulated the OS level endured by zebra finches (<i>Taeniopygia guttata</i>) during their development by transitorily inhibiting the synthesis of the key antioxidant glutathione ('early-high-OS'). The offspring of these birds and control parents were cross-fostered at hatching to enlarge or reduce its brood size. Independently of parents' early-life OS levels, the chicks raised in enlarged broods showed lower erythrocyte glutathione levels, revealing glutathione sensitivity to environmental conditions. Control ("early-low-OS") biological mothers produced females, not males, that attained a higher body mass when raised in a benign environment (i.e. the reduced brood). In contrast, biological mothers exposed to early-life OS produced heavier males, not females, when allocated in reduced broods. Early-life OS also affected the parental rearing capacity because 12d-old nestlings raised by a foster pair with both early-high-OS members grew shorter legs (tarsus) than chicks from other groups. The results indicate that environmental conditions during development can affect early glutathione levels, which may, in turn, influence the next generation through both pre- and postnatal parental effects. The results also demonstrate that early-life OS can constrain the offspring phenotype.</p>
