Time spent in distinct life-history stages has sex-specific effects on reproductive fitness in wild Atlantic salmon
<p><span>In species with complex life cycles, life history theory predicts that fitness is affected by conditions encountered in previous life history stages. Here, we use a four-year pedigree to investigate if time spent in two distinct life history stages has sex-specific reproductive fitness consequences in anadromous Atlantic salmon (<i>Salmo salar</i>). We determined the amount of years spent in fresh water as juveniles (freshwater age, FW, measured in years), and years spent in the marine environment as adults (sea age, SW, measured in sea winters) on 264 sexually mature adults collected on a river spawning ground. We then estimated reproductive fitness as the number of offspring (reproductive success) and the number of mates (mating success) using genetic parentage analysis (>5000 offspring). Sea age is significantly and positively correlated with reproductive and mating success of both sexes whereby older and larger individuals gained the highest reproductive fitness benefits (females: 62.2% increase in offspring/SW and 34.8% increase in mate number/SW; males: 201.9% offspring/SW and 60.3% mates/SW). Younger freshwater age was significantly related to older sea age and thus increased reproductive fitness, but only among females (females: -33.9% offspring/FW and -32.4% mates/FW). This result implies that females can obtain higher reproductive fitness by transitioning to the marine environment earlier. In contrast, male mating and reproductive success was unaffected by freshwater age and more males returned at a younger age than females despite the reproductive fitness advantage of later sea age maturation. Our results show that the timing of transitions between juvenile and adult phases has a sex-specific consequence on female reproductive fitness, demonstrating a life-history trade-off between maturation and reproduction in wild Atlantic salmon.</span></p>
Listening preferences for the different reproduction systems Stereo, Surround, and Wave Field Synthesis in the context of popular music
<p>We did a paired comparison preference test where listeners rated their listening preference for four different pop musical pieces presented by WFS, stereo or surround. The musical pieces were all mixed by the same person in order to try to minimize the influence of the mix on the ratings, but still trying to get the best out of every system, see [1] for details. The mixes are available at https://doi.org/10.14279/depositonce-5173.</p> <p>Here, we provide the results of the 22 listeners that participated in the experiment together with an analysis which calculates a Bradley-Terry-Luce model after Wickelmayer et al.

Listening position preference for different 5.0 reproductions -- data
<p>We performed an experiment which investigated the preferred listening position<br> in a 5.0 surround setup out of nine different positions while listening to a<br> classical piece of music.<br> The test was performed by binaural synthesis in order to allow instantaneous<br> switching between the different positions and was performed first without<br> indicating to the participants where they are located in the virtual setup and a<br> second run, where they got visual feedback on their virtual position.</p> <p>The experiment was repeated for six different recording techniques, that captured the Mozart performance simultaneously [2].</p> <p>See README.md for more details.</p> <p>[1] https://github.com/SoundScapeRenderer/ssr</p> <p>[2] Wittek, H.

Speed discrimination and distance reproduction data.
<p><strong>Data related to the following publication:</strong></p> <p>Jan Churan, Johannes Paul, Steffen Klingenhoefer, Frank Bremmer (in press), Integration of visual and tactile information in reproduction of traveled distance. Journal of Neurophysiology. doi: 10.1152/jn.00342.2017</p> <p><strong>Description:</strong></p> <p>Speed discrimination</p> <p>In the speed discrimination task, the subject was presented with a standard stimulus and a comparison stimulus (each 2 s long with a break of 500 ms in between). The standard stimulus was always presented first at a speed of either 3, 5 or 7 arbitrary units (AU)/s. The comparison stimulus was chosen from a range of +- 2 AU/s around the speed of the standard stimulus. After both stimuli had been presented, subjects had to indicate which one was perceived as faster by pressing one of two buttons. The combination of three standard speeds and two modality conditions resulted in 6 experimental conditions. In each condition 41 trials were performed that covered the given range of +- 2 AU/s in equidistant steps of 0.1 AU/s. In this discrimination task, each experimental condition was presented only once. The trials were conducted in a pseudo-randomized order.</p> <p>Distance reproduction</p> <p>In the first experiment, we tested the ability of the subjects to reproduce a previously passively observed traveled distance using visual, tactile or bi-modal feedback. The subject was presented with a simulation of self-motion over a certain distance. The speeds during this presentation were always constant at 4 or 7 AU/s and the distances were either 5, 10 or 15 AU. In this first phase the stimulation was always bi-modal. After this presentation and a brief pause of 500 ms the task of the subject was to reproduce the passively observed distance using a joystick. In this second part either only the visual information, only the tactile information, or both modalities were available. The order of all conditions was pseudo-random.</p> <p>Re-scaling of tactile information</p> <p>In the second experiment we investigated the effect of re-scaling of tactile information on the reproduced traveled distance. All simulated self-motion was bi-modal. The subjects were passively observing a simulated self-motion over a certain distance. The speed of this motion was not constant but had a sinusoidal profile with a peak speed at either 5 or 7 AU/s. The traveled distances were either 10, 15 or 20 AU. After the first presented distance and a brief gap of 500 ms another distance was presented passively. The speed profile of this second movement consisted of three different speeds between 3 AU/s and 10 AU/s. The distance covered by this second passive movement was always one third of the first passive distance but the subjects were neither informed about nor aware of this relationship. After the second presentation had stopped, the task of the subjects was to actively reproduce the first observed distance as a sum of the second passively observed distance and the subsequent active motion. In random 10% of the trials the tactile component of the motion was scaled up by 25% and in another 10% of the trials it was down-scaled by 25%. This means that the speed of the air flow on these trials was 25% faster (or slower) than in the rest of the trials. The re-scaling was applied only during the second passive motion and the active reproduction part of each trial. The subjects were not informed about and were not aware of this manipulation.</p> <p>The experiments on distance reproduction and tactile rescaling were performed in two variations that differed in the relationship between the speed of the tactile stimulus and the speed of self-motion. While in the congruent condition the speed of the air flow was directly proportional to the speed of visual self-motion, in the incongruent condition the relation of the two measures was inversely proportional. The congruent and the incongruent configurations were always used in both, the presentation as well as in the reproduction phase of a trial. Importantly, a purely visual stimulation used in the two conditions was identical in both cases. The subjects were informed that in the incongruent experiments slow speed of air flow indicates a fast speed of self-motion. To avoid any confusion, separate groups of subjects were tested in the congruent and in the incongruent conditions.</p>

Reproduction package for "A strong H− opacity signal in the near-infrared emission spectrum of the ultra-hot Jupiter KELT-9b"
<p>This is a basic reproduction package for the paper "A strong H− opacity signal</p><p>in the near-infrared emission spectrum of the ultra-hot Jupiter KELT-9b"</p><p>by [Jacobs, B.; Désert, J. -M.; Pino, L. et al. (2022)](https://doi.org/10.1051/0004-6361/202244533).</p><p> </p><p>Abstract:</p><p>We present the analysis of a spectroscopic secondary eclipse of the hottest transiting exoplanet detected to date, KELT-9b, obtained with the Wide Field Camera 3 aboard the <i>Hubble</i> Space Telescope. We complement these data with literature information on stellar pulsations and <i>Spitzer</i>/Infrared Array Camera and Transiting Exoplanet Survey Satellite eclipse depths of this target to obtain a broadband thermal emission spectrum. Our extracted spectrum exhibits a clear turnoff at 1.4 μm. This points to H− bound-free opacities shaping the spectrum. To interpret the spectrum, we perform grid retrievals of self-consistent 1D equilibrium chemistry forward models, varying the composition and energy budget. The model with solar metallicity and C/O ratio provides a poor fit because the H− signal is stronger than expected, requiring an excess of electrons. This pushes our retrievals toward high atmospheric metallicities ([M/H] = 1.98−0.21+0.19) and a C/O ratio that is subsolar by 2.4<i>σ</i>. We question the viability of forming such a high-metallicity planet, and therefore provide other scenarios to increase the electron density in this atmosphere. We also look at an alternative model in which we quench TiO and VO. This fit results in an atmosphere with a slightly subsolar metallicity and subsolar C/O ratio ([M/H] = −0.22−0.13+0.17, log (C/O) = −0.34−0.34+0.19). However, the required TiO abundances are disputed by recent high-resolution measurements of the same planet.</p>
Reproduction package for "Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b"
<p>This is a basic reproduction package for the paper "Probing reflection from</p><p>aerosols with the near-infrared dayside spectrum of WASP-80b"</p><p>by [Jacobs, B.; Désert, J. -M.; Gao P. et al. (2023)](https://doi.org/10.3847/2041-8213/acfee9).</p><p>Abstract:</p><p>The presence of aerosols is intimately linked to the global energy budget and the composition of a planet's atmospheres. Their ability to reflect incoming light prevents energy from being deposited into the atmosphere, and they shape spectra of exoplanets. We observed five near-infrared secondary eclipses of WASP-80b</p><p>with the Wide Field Camera 3 (WFC3) aboard the Hubble Space Telescope to provide constraints on the presence and properties of atmospheric aerosols.</p><p>We detect a broadband eclipse depth of 34\pm10 ppm for WASP-80b. We detect a higher planetary flux than expected from thermal emission alone at 1.6 sigma, which hints toward the presence of reflecting aerosols on this planet's dayside, indicating a geometric albedo of A_g<0.33 at 3 sigma.</p><p>We paired the WFC3 data with Spitzer data and explored multiple atmospheric models with and without aerosols to interpret this spectrum.</p><p>Albeit consistent with a clear dayside atmosphere, we found a slight preference for near-solar metallicities and for dayside clouds over hazes. We exclude soot haze formation rates higher than 10^{-10.7} g cm^{-2} s^{-1} and tholin formation rates higher than 10^{-12.0} g cm^{-2} s^{-1} at 3 sigma.</p><p>We applied the same atmospheric models to a previously published WFC3/Spitzer transmission spectrum for this planet and found weak haze formation.</p><p>A single soot haze formation rate best fits both the dayside and the transmission spectra simultaneously. However, we emphasize that no models provide satisfactory fits in terms of the chi-square of both spectra simultaneously, indicating longitudinal dissimilarity in the atmosphere's aerosol composition.</p>
Paternal environment effects are driven by female reproductive fluid but not sperm age in an external fertiliser
<p>Sperm ageing after ejaculation can generate paternal environmental effects that impact offspring fitness. In many species, female reproductive fluids (FRFs), i.e. ancillary fluids released by eggs or within the female reproductive tract, may protect sperm from ageing and can additionally interact with sperm to influence offspring viability. This raises the intriguing prospect that FRFs may alleviate paternal effects associated with sperm ageing. Here, we test this novel hypothesis using the broadcast spawning mussel, <em>Mytilus galloprovincialis.</em> We show that incubating sperm in FRF prior to fertilisation increases offspring viability and that these effects occur independently of sperm age. Our results provide novel evidence that FRFs allow females to selectively bias fertilisation toward higher quality sperm within an ejaculate, which in turn yields more viable offspring. We consider this FRF-mediated paternal effect in the context of female physiological control over fertilisation and the transgenerational effects of female-regulated haploid selection.</p>
