Present and future distribution models for chestnut in the Iberian Peninsula
<p>Current and future distribution of chestnut trees in the Iberian Peninsula developed in the manuscript "<strong>Impact of climate change over distribution and potential range of chestnut in the Iberian Peninsula</strong>"</p> <p>These predictions were derived through computational modeling utilizing various environmental parameters. Specifically, the model integrated topographical features such as slope, northness (cosine of aspect), or eastness (sine of aspect), soil attributes including pH and soil organic carbon content (SOC), and bioclimatic variables sourced from the CHELSA V.2.1 dataset.</p> <p><br>File Naming Convention Explanation:</p> <p>"C_sativa_current.tif" denotes the model representing the current distribution of C. sativa.</p> <p>In other instances, such as "C_sativa_md_ensemble_ssp370_2011-2040.tif":</p> <ul> <li>"md_ensemble" indicates the median ensemble, while "mn_ensemble" signifies the mean ensemble.</li> <li>In cases where the model is solely based on a General Circulation Model (GCM), the term "md_ensemble" or "mn_ensemble" is replaced by the specific model used.</li> <li>"ssp370" or "ssp585" corresponds to the climate change scenario derived from CMIP6 GCMs.</li> <li>The timeframe "2011-2040," "2041-2070," or "2071-2100" denotes the period under evaluation.</li> </ul>
Compiled eruption chronostratigraphy including eruption styles for Santorini volcano, Greece, from ~360 ka to present day
<p>This dataset is a compiled chronostratigraphy for the volcanic island of Santorini, Greece. It comprises information on eruption dates, dating methods and numbers of eruptions of each type (Plinian, interplinian and lava), compiled from existing published sources (all references provided) and some supplementary fieldwork. The record is detailed and quantitative from the present day back to 224 ka, and less detailed and qualitative from 224 ka back to ~360 ka. Two maps are provided to give location context for the dataset, as well as a reference list, and other associated reading. This dataset forms part of the supplementary information for the publication 'Eruptive Activity of the Santorini Volcano Controlled by Sea Level Rise and Fall' by Satow et al. (2021) in Nature Geoscience- <a href="https://doi.org/10.1038/s41561-021-00783-4">https://doi.org/10.1038/s41561-021-00783-4</a></p>
Deep-time convergent evolution in animal communication presented by shared adaptations for coping with noise in lizards and other animals
<p>Convergence in communication appears rare compared to other forms of adaptation. This is puzzling, given communication is acutely dependent on the environment and expected to converge in form when animals communicate in similar habitats. We uncover deep-time convergence in territorial communication between two groups of tropical lizards separated by over 140 million years of evolution: the Southeast Asian Draco and Caribbean Anolis. These groups have repeatedly converged in multiple aspects of display along common environmental gradients. Robot playbacks to free-ranging lizards confirmed the most prominent convergence in display is adaptive, as it improves signal detection. We then provide evidence from a sample of the literature to further show convergent adaptation among highly divergent animal groups is almost certainly widespread in nature. Signal evolution is therefore curbed towards the same set of adaptive solutions, especially when animals are challenged with the problem of communicating effectively in noisy environments.</p>

Metrics Literacies: On the State of the Art of Multimedia Scholarly Metrics Education (Video presentation)
<p>Scholarly metrics, such as h-index or impact factor, are widely applied in academic tenure and funding decisions but often inappropriately. The quantification of research impact has created a pressure to publish that harms all scholarly disciplines by creating adverse effects, such as plagiarism, gratuitous self-citation, and honorary authorship. The Metrics Literacies project led by Prof. Stefanie Haustein aims to reduce the misuse of metrics and adverse effects by improving the understanding and use of scholarly metrics in academia through the development, testing, and dissemination of multimedia resources. This poster talk shows the current state of the art on the project.</p>
