“…The toad-headed agama (P. przewalskii) is a small diurnal lizard (snout-vent length [SVL] up to 60 mm), that is widely distributed in the desert, semi-desert and grassland habitats of northern China (Zhao, Zhao, & Zhou, 1999). The lizard usually achieves maturity at the age of two years with a minimum SVL of 40 mm.…”

A major goal of seasonal biology is to understand how selection on phenology and the physiological niche interact. In oviparous species, fitness variation across the growing season suggests that phenological shifts will alter selective environments experienced by embryos. We hypothesize that physiology could become co‐adapted with phenology; such that embryos perform better in the environmental conditions they are adapted to compared to embryos adapted to other environments (temporal matching). Here, we tested for temporal matching to seasonal changes in the environmental temperatures with toad‐headed lizard, Phrynocephalus przewalskii, which inhabits the temperate desert steppe of China. We used a split‐clutch reciprocal experiment, by incubating eggs from early‐ and late‐breeding females at rising and falling temperature regimes, respectively, to separate the influence of intrinsic (genetic and parental) vs. extrinsic factors (developmental plasticity or acclimatization) on the performance and fitness of offspring. Eggs from early‐breeding females were with higher quality than those from late‐breeding females, likely due to better maternal provisioning. Offspring from early‐breeding females had higher selected body temperatures and metabolic rates than those from late‐breeding females. Falling temperatures that may indicate the end of the growing season, reduced incubation duration and increased metabolic rates for both early and late eggs, compared to rising temperatures. Late hatchlings had higher growth rates when incubated at falling compared to rising temperatures, while growth rates of early hatchlings were not sensitive to incubation temperature. Thus, growth and survival rates of late embryos were similar to early embryos under falling temperatures, despite early embryos being of generally higher quality. Overall, our study confirms that “early is higher quality.” Intrinsic factors dominate offspring performance and fitness, with a general advantage for early embryos throughout the season. We found some support for temporal matching, demonstrating that late embryos with lower quality have physiological strategies that are specialized to late‐season environments, allowing them to attain similar fitness in late‐season environments to that of early embryos.

“…The higher Q -factor (quality factor, Q = f 0 /Δ f ) indicates that the resonant peak is sharper, and the frequency selection of the device is stronger. The high Q -factor indicates that this device can be used in sensors with frequency selectivity . The Δ f , Q -factors, and absorption modes at different resonant frequency points are listed in Table .…”

In this paper, we design a metasurface terahertz perfect absorber with multi-frequency selectivity and good incident angle compatibility using a double-squared open ring structure. Simulations reveal five selective absorption peaks located at 0−1.2 THz with absorption 94.50% at 0.366 THz, 99.99% at 0.507 THz, 95.65% at 0.836 THz, 98.80% at 0.996 THz, and 86.70% at 1.101 THz, caused by two resonant absorptions within the fundamental unit (fundamental mode of resonance absorption, FRA) and its adjacent unit (supermodel of resonance absorption, SRA) in the structure, respectively, when the electric field of the electromagnetic wave is incident perpendicular to the opening. The strong frequency selectivity at 0.836 THz with a Q-factor of 167.20 and 0.996 THz with a Q-factor of 166.00 is due to the common effect of the FRA and SRA. Then, the effect of polarized electromagnetic wave modes (TE and TM modes) at different angles of incidence (θ) and the size of the open rings on the device performance is analyzed. We find that for the TM mode, the absorption of the resonance peak changes only slightly at θ = 0−80°, which explains this phenomenon. The frequency shift of the absorption peaks caused by the size change of the open rings is described reasonably by an equivalent RLC resonant circuit. Next, by adjusting two-dimensional materials and photosensitive semiconductor materials embedded in the unit structure, the designed metasurface absorber has excellent tunable modulation. The absorption modulation depth (MD) reaches ≈100% using the conductivity of photosensitive semiconductor silicon (σ SI-ps ), indicating excellent control of the absorption spectrum. Our results can greatly promote the absorption of terahertz waves, absorption spectrum tunability, and frequency selectivity of devices, which are useful in the applications such as resonators, biodetection, beam-controlled antennas, hyperspectral thermal imaging systems, and sensors.

Toe fringe is the most typical morphological feature of lizards 4 adapted to sandy environments, and toe fringe is suitable for testing the 5 adaptive convergence suggested by form-environment correlations. 6Phrynocephalus mystaceus mainly lives in dune habitats, has a developed 7 bilateral toe fringe, and exhibits fast sand-diving behavior for predator 8 avoidance. We tested the effects of resecting the medial and bilateral toe 9 fringes on the locomotor performance and sand-diving performance of P. 1 0 mystaceus. The results showed that the individuals that had their medial 1 1 toe fringe removed exhibited significantly faster sprint speeds than the 1 2 unresected and all resected individuals (P <0.05). The results of stepwise 1 3 regression analysis show that the relative area of the toe fringe is an 1 4 important morphological feature that affects locomotor performance. The 1 5 sand-burial performance scores of the unresected individuals were 1 6 significantly greater than those of the resected individuals (P <0.05). The 1 7 results of stepwise regression analysis show that the relative area of toe 1 8 fringe and the axilla-groin length are the main morphological features that 1 9 3 1
