Complex genetic patterns and distribution limits mediated by native congeners of the worldwide invasive red‐eared slider turtle
<p>Non-native (invasive) species offer a unique opportunity to study the geographic distribution and range limits of species, wherein the evolutionary change driven by interspecific interactions between native and non-native closely related species is a key component. The red-eared slider turtle, <i>Trachemys scripta elegans</i> (TSE), has been introduced and successfully established worldwide. It can coexist with its native congeners <i>T. cataspila</i>, <i>T. venusta</i> and <i>T. taylori</i> in Mexico. We performed comprehensive fieldwork, executed a battery of genetic analyses and applied a novel species distribution modeling approach to evaluate their historical lineage relationships and contemporary population genetic patterns. Our findings support the historical common ancestry between native TSE and non-native (TSE<sub>alien</sub>), while also <span>highlighting the genetic differentiation of the exotic lineage. G</span>enetic patterns are associated with their range size/endemism gradient, the microendemic <i>T. taylori</i> showed significant reduced genetic diversity and high differentiation, whereas TSE<sub>alien</sub><span> showed </span>the highest diversity and signals of population size expansion. Counter to our expectations, <span>lower naturally occurring distribution overlap and little admixture patterns </span>were found<span> between TSE and its congeners, exhibiting reduced gene flow and clear genetic separation across neighboring species despite having zones of contact. We demonstrate that</span> these native <i>Trachemys</i> species have distinct climatic niche suitability, likely preventing establishment of and displacement by the TSE<sub>alien</sub>. Moreover, we <span>found </span>major niche overlap between TSE<sub>alien </sub>and native species worldwide, supporting our prediction that sites with closer ecological optima to the invasive species have higher establishment risk than those that are closer to the niche-center of the native species.</p>

Contrasted-Fertilization Wheat Ear Dataset 2020
<p><strong>Overview</strong></p> <p>This dataset contains 701 wheat RGB images in which all the ears have been manually labelled with bounding boxes. Its primary function is to provide training or test data for deep learning models aiming at the detection of wheat ears. In terms of diversity, it integrates wheat images from two varieties, at all the key development stages from heading to maturity, and for four or eight contrasted nitrogen fertilization management. </p> <p><strong>Field experiments and image acquisition</strong></p> <p>Images were acquired during the 2020 season in two trial fields located in the Hesbaye area, Belgium. The images were captured by two RGB cameras in nadir position. Those cameras were positioned on the cantilever beam to avoid shadows from the phenotyping platform. The auto-exposure algorithm was tuned to prevent, as possible, image saturation. All the details regarding the field experiments and the image acquisition can be found in the related paper: "Dandrifosse S., Ennadifi E., Carlier A., Gosselin B., Dumont B. & Mercatoris B., 2022.

Beyond the exponential horn: a bush-cricket with ear-canals which function as coupled resonators
<p>Bush-crickets have dual-input, tympanal ears located in the tibia of their forelegs. The sound will, first of all, reach the external sides of the tympana, before arriving to the internal sides through the bush-cricket ear-canal, the acoustic trachea (AT), with a phase lapse and pressure gain. It has been shown that for many bush-crickets, the AT has an exponential horn-shaped morphology and function, producing a significant pressure gain above a certain cut-off frequency. However, the underlying mechanism of different AT designs remains elusive. In this study, we demonstrate that the AT of the duetting bush-cricket <em>Pterodichopetala</em> <em>cieloi</em> function as coupled resonators, producing sound pressure gains at the sex-specific conspecific calling song frequency, and attenuating the remainder – a functioning mechanism significantly different than an exponential horn. Furthermore, it is demonstrated that despite the sexual dimorphism between the <em>P</em>. <em>cieloi</em> AT, both male and female AT have a similar biophysical mechanism. The analysis was carried out using an interdisciplinary approach, where micro-computed tomography was used for the morphological properties of the <em>P</em>. <em>cieloi</em> AT, and a finite-element analysis was applied on the precise tracheal geometry to further justify the experimental results and to go beyond experimental limitations.</p>

Modeling of Speech-dependent Own Voice Transfer Characteristics for Hearables with In-ear Microphones: Audio Examples
<p>This upload contains audio examples for the preprint "Modeling of Speech-dependent Own Voice Transfer Characteristics for Hearables with In-ear Microphones".</p> <p>The audio files correspond to subplots of the spectrogram shown in the default preview, starting from the upper left corner (subplot 0) to the upper right corner (subplot 1) and so on.</p> <h2>Abstract</h2> <p>Many hearables contain an in-ear microphone, which may be used to capture the own voice of its user. However, due to the hearable occluding the ear canal, the in-ear microphone mostly records body-conducted speech, typically suffering from band-limitation effects and amplification at low frequencies. Since the occlusion effect is determined by the ratio between the air-conducted and body-conducted components of own voice, the own voice transfer characteristics between the outer face of the hearable and the in-ear microphone depend on the speech content and the individual talker. In this paper, we propose a speech-dependent model of the own voice transfer characteristics based on phoneme recognition, assuming a linear time-invariant relative transfer function for each phoneme. We consider both individual models as well as models averaged over several talkers. Experimental results based on recordings with a prototype hearable show that the proposed speech-dependent model enables to simulate in-ear signals more accurately than a speech-independent model in terms of technical measures, especially under utterance mismatch and talker mismatch. Additionally, simulation results show that talker-averaged models generalize better to different talkers than individual models.</p> <p> </p> <p>The examples are also available here: <a href="https://m-ohlenbusch.github.io/own_voice_modeling_examples/" target="_blank" rel="noopener">https://m-ohlenbusch.github.io/own_voice_modeling_examples/</a></p> <p>Arxiv preprint: <a href="https://arxiv.org/abs/2310.06554">https://arxiv.org/abs/2310.06554</a></p>

Data from: Intraspecific variation and symmetry of the inner-ear labyrinth in a population of wild turkeys: implications for paleontological reconstructions
The cochlea and semicircular canals of the inner ear are vital neurosensory devices. There are associations between the anatomy of these sensorineural structures, their function, and the function of related biological systems, e.g., hearing ability, gaze stabilization, locomotor agility, and posture. The endosseous labyrinth is frequently used as a proxy to infer the performance of the hearing and vestibular systems, locomotor abilities, and ecology of extinct species. Such fossil inferences are often based on single specimens or even a single ear, representing an entire species. To address whether a single ear is representative of a population, we used geometric morphometrics to quantitatively assess the variation in shape and symmetry in a sample of endosseous labyrinths of wild turkeys Meleagris gallopavo of southern Ohio. We predicted that ears would be symmetrical both within individuals and across the sample; that labyrinth shape and size would covary; that labyrinth shape would vary with the size of the brain, measured as width of the endocranium at the cerebellum; and that labyrinths would be morphologically integrated. To test these predictions, we microCT-scanned the heads of 26 cadaveric turkeys, digitally segmented their endosseous labyrinths in Avizo, and assigned 15 manual landmarks and 20 sliding semilandmarks to each digital model. Following Procrustes alignment, we conducted an analysis of bilateral symmetry, a Procrustes regression analysis for allometry and other covariates including side and replicate, and analyses of global integration and modularity. Based on Procrustes distances, no individual's left and right ears were clearly different from each other. When comparing the ears of different specimens, statistically clear differences in shape were found in only 66 of more than 1300 contrasts. Moreover, effects of both directional and fluctuating asymmetry were very small—generally, two orders of magnitude smaller than the variance explained by individual variation. Statistical tests disagreed on whether these asymmetric effects crossed the threshold of significance, possibly due to non-isotropic variation among landmarks. Regardless, labyrinths appeared to primarily vary in shape symmetrically. Neither labyrinth size nor endocranial width was correlated with labyrinth shape, contrary to our expectations. Finally, labyrinths were found to be moderately integrated in a global sense, but four weakly separated modules—the three semicircular canals and cochlea—were recovered using a maximum-likelihood analysis. The results show that both fluctuating and directional asymmetry play a larger role in shape variation than expected—but nonetheless, endosseous labyrinths are symmetrical within individuals and at the level of the population, and their shape varies symmetrically. Thus, inferences about populations, and very possibly species, may be confidently made when only a single specimen, or even a single ear, is available for study.
