Position in the laying order has sex-specific consequences for reproductive success in adult black-headed gulls
<p><span>Mothers who produce multiple offspring within one reproductive attempt often allocate resources differentially; some maternally-derived substances are preferentially allocated to last-produced offspring and others to first-produced offspring. The combined effect of these different allocation regimes on the overall fitness of offspring produced early or late in the sequence is not well understood, partly because production order is often coupled with birth order, making it difficult to separate effects of pre-natal maternal allocation from those of post-natal social environments. In addition, very little is known about the influence of laying order on fitness in later-life. In this study, we used a semi-natural captive colony of black-headed gulls to test whether an offspring's position in the laying order affected its early life survival and later life reproductive success, independent of its hatching order. Later-laid eggs were less likely to hatch, but among those that did, survival to adulthood was greater than that of first-laid eggs. In adulthood, the laying order of females did not affect their likelihood of breeding in the colony, but male offspring hatched from last-laid eggs were significantly less likely to gain a breeding position than earlier-laid males. In contrast, later-laid female parents hatched lower proportions of their clutches than first-laid females, but hatching success was unrelated to the laying order of male parents. Our results indicate that gull mothers induce complex and sex-specific effects on both the early survival of their offspring and on long-term reproductive success through laying order effects among eggs of the same breeding attempt.<strong> </strong></span></p>

<p><strong>DESCRIPTION</strong></p> <p><strong>BinMov2023: Binaural Dataset for Source Position Estimation with Head Rotation and Moving Listeners</strong> is a binaural dataset containing synthetic data of single source speech signals reverberated with simulated room impulse responses. The data allows for experiments related to audio tasks of sound source localization and sound distance estimation. <br>The dataset consists of three subsets, related to three different scenarios:</p> <p>- static: a static sound source and a static listener<br>- rotation: a static sound source and a static listener with a head rotating in the azimuth plane<br>- walking: a static sound source and a listener moving in space</p> <p>Each sound file contains a unique combination of a simulated room and source and receiver positions. The walking scenario contains simulations of 2500 different rooms, whereas the static and rotation scenarios contain 5000 rooms. </p> <p> </p> <p><strong>REPORT AND REFERENCE</strong></p> <p>A detailed description of the dataset and the data generation process can be found in:</p> <p>D.
