Variation in incubation length and hatching asynchrony in Eastern Kingbirds: weather eclipses female effects
<p>Incubation length and hatching asynchrony are integral elements of the evolved reproductive strategies of birds and here we here quantify intra- and interpopulation variation in both traits for Eastern Kingbird (<i>Tyrannus tyrannus</i>) populations from New York (NY), Kansas (KS), and Oregon (OR). Multiple samples from a subset of females demonstrated that neither incubation length nor hatching asynchrony was repeatable, that both traits varied with a female trait (clutch size), but that variation in both incubation length and hatching asynchrony was to a substantial degree linked to weather, namely ambient temperature and precipitation. Incubation length exhibited the same median (15 days) and range (13 to 17 days) at all sites, and model selection results indicated that incubation periods were longer in NY than KS, among the smallest and largest clutches, when rain was frequent throughout the period when eggs were in the nest, in replacement nests, and likely when ambient temperatures were low during egg-laying. Full hatching usually required 2 days (but up to 3), and more synchronous hatching was associated with small clutch size, short incubation periods, frequent rain during the egg-laying period, and low ambient temperatures during the first half of incubation. Only 5% to 9% of nestlings starved and starvation was not associated with greater hatching asynchrony, indicating the nestling starvation was likely not a cost of hatching asynchrony. Thus, although clutch size, a female trait, contributed to variation in incubation length and hatching asynchrony, weather was a greater source of variation, especially for incubation length. Weather thus influences length of exposure of eggs to destructive forces (predators and severe weather), and as a consequence, climate change has the potential to influence reproductive success.</p>
Trachemys scripta gene expression data under constant and fluctuating incubation temperatures
<p>There is ample research demonstrating that temperature can have complex effects on biological processes, including the timing of when organisms respond to temperature; some responses occur rapidly while others require an extended exposure time. However, most of what we know about temperature effects comes from studies using constant temperature conditions, which are not reflective of natural, fluctuating temperatures. Species with temperature-dependent sex determination (TSD) present an ideal system to study the temporal aspects of the temperature response because prior research has established a number of temperature-responsive genes involved in TSD, albeit under constant temperatures. To investigate potential differences in the timing of sexual development between constant and fluctuating incubation temperatures, we exposed <em>Trachemys scripta</em> embryos to two conditions that produce males (constant 26°C and 26 ± 3°C) and two that produce females (constant 31°C and 31 ± 3°C), and sampled embryonic gonads for gene expression analysis via qPCR.We analyzed three genes involved in testis differentiation (<em>Kdm6b</em>, <em>Dmrt1</em>, and <em>Sox9</em>) and two genes involved in ovary differentiation (<em>Foxl2</em> and <em>Cyp19A1</em>). Results show that <em>Kdm6b</em> expression was significantly lower under fluctuating temperatures compared to constant temperatures. <em>Foxl2 </em>and <em>Cyp19A1</em> expression were also lower under fluctuating temperatures, but not at all stages of development. These results suggest that constant temperatures caused increases in both <em>Foxl2</em> and <em>Cyp19A1</em> expression earlier (developmental stage 20) than fluctuating temperatures (stages 22 and 23). <em>Dmrt1</em> and <em>Sox9</em> expression did not differ between constant and fluctuating temperatures. These results highlight that not all genes in a temperature-dependent process respond to temperature in the same manner. Whether there are functional consequences of this variation remains to be determined.</p>

Data from: Association between the severity of influenza A(H7N9) virus infections and length of the incubation period
Background: In early 2013, a novel avian-origin influenza A(H7N9) virus emerged in China, and has caused sporadic human infections. The incubation period is the delay from infection until onset of symptoms, and varies from person to person. Few previous studies have examined whether the duration of the incubation period correlates with subsequent disease severity. Methods and Findings: We analyzed data of period of exposure on 395 human cases of laboratory-confirmed influenza A(H7N9) virus infection in China in a Bayesian framework using a Weibull distribution. We found a longer incubation period for the 173 fatal cases with a mean of 3.7 days (95% credibility interval, CrI: 3.4–4.1), compared to a mean of 3.3 days (95% CrI: 2.9–3.6) for the 222 non-fatal cases, and the difference in means was marginally significant at 0.47 days (95% CrI: -0.04, 0.99). There was a statistically significant correlation between a longer incubation period and an increased risk of death after adjustment for age, sex, geographical location and underlying medical conditions (adjusted odds ratio 1.70 per day increase in incubation period; 95% credibility interval 1.47–1.97). Conclusions: We found a significant association between a longer incubation period and a greater risk of death among human H7N9 cases. The underlying biological mechanisms leading to this association deserve further exploration.
Data from: Plasticity in incubation behavior and shading by king rails (Rallus elegans) in response to temperature
King rails experience a wide range of temperatures during the course of the breeding season throughout their rapidly contracting geographic range. Incubating parent birds are adapted to keep their eggs within a temperature range appropriate for embryo development, but king rail clutches are at risk of exceeding lethal temperatures in the latter half of the nesting season. We investigated whether behavioral plasticity during incubation enables parents to maintain clutch temperature within tolerable limits for embryo development. Video revealed that king rail parents interrupted incubation to stand above and shade their eggs. We tested the hypothesis that the onset of shading was a direct response to ambient temperature (adaptive plasticity). We monitored clutch temperature directly by experimentally adding into clutches a model egg embedded with a programmable iButton. We measured ambient temperature at the nest site simultaneously. Parents spent proportionately more time shading and less time incubating their eggs at higher ambient temperatures. Shading may primarily function in cooling the parent. The frequency and duration of shading bouts were significantly greater at higher ambient temperatures. Parents also took more frequent but shorter recesses in hotter conditions. Diurnal recesses exposed eggs to direct sunlight, and the highest clutch temperatures were recorded under these conditions. Complete hatching failure in at least one nest was attributable to high clutch temperature for an extended period. Because mean ambient temperature increases throughout the breeding season, we investigated seasonal patterns in onset of incubation and its effect on hatching rate. Later in the season, parents tended to initiate incubation earlier, and hatching asynchrony increased significantly. Together these results suggest that breeding king rails may be constrained in their ability to cope with sustained high temperatures should seasonal averages continue to rise as predicted.
