Sex-specific shifts in morphology and diet in a frog after 50 years of anthropogenic habitat fragmentation
<p><span>Aim:</span><span> Phenotypic shifts are commonly observed when animals face insular habitat change and may reflect ongoing stresses on individuals. However, the generality and the driving processes of this 'island rule' remain equivocal, notably in amphibians. Here, we</span> <span>investigate both morphological and dietary shifts in a frog using a mosaic of human-created islands to assess the potential operating mechanisms underlying these phenotypic responses</span>.</p> <p><span>Location: </span><span>Thousand Island Lake, China.</span></p> <p><span>Taxon: </span><span>The Chinese piebald odorous frog, Odorrana schmackeri.</span></p> <p><span>Results:</span><span> W</span>e found insular dwarfism in female<span> but not male</span> frogs.<span> Meanwhile, insular females also had smaller gape widths after accounting for snout-vent lengths (SVLs) than mainland females. According to SEMs</span>, resource availability <span>had a direct positive effect on </span>body size. <span>Finally, d</span>iet composition <span>differed</span> between island and mainland<span> populations, but only in females. Males and females on islands</span> exhibited <span>greater</span> <span>overlaps in </span>diet.</p> <p><span>Main conclusions:</span><span> In contrast with most studies in amphibians</span><span>, we found insular dwarfism rather than gigantism in females. The smaller gape width after accounting for SVL in insular females suggests potential changes in prey utilization or food availability on these human-created islands. This notion is </span><span>further </span><span>supported</span><span> by the differentiation of diet composition between island and mainland females. The higher diet overlap between sexes implies stronger intersexual competition for food resources after habitat fragmentation. Overall, we found shifts in morphology and diet in frogs which may implicate the influence of habitat fragmentation and underscores the need to consider intersexual differences when assessing responses of species to anthropogenic disturbances.</span></p>
visualizing the developement of painting production in periods of 50 years from 1300 to 2000 (source: https://kor.uni-frankfurt.de)
<p>Data<br> * entities representing a painting were selected<br> ** since there is no classification of works of art in the database, a set of values describing the technical and material features of the works of art were used to filter works of art being most probably paintings. The filter values can be found in ../../unique_material_values_new.xlsx on tabs "Öl auf Leinwand" and "Tafelmalerei"<br> * the selected entities were classified in periods of 50 years starting in 1300 and ending in 2000. Additionally there were two classes for paintings before 1300 and after 2000, and a class for non dated painting entities<br> * for each of the classes, the proprtion of its cardinal number in respect to the global number of selected entities was calculated<br> * class labels and the calculated proportion were written in data.csv (column 1: class labels, column 2: proprtion)</p> <p>Processing<br> * script that creates a bar chart from data in data.tsv<br> ** the script uses d3.js</p> <p> </p>
50 Years of Art Song & Gender on Major European Stages, Part 1 (Austria): Vienna's Konzerthaus, Musikverein & Salzburg Festspiele Song Recitals 1970 - 2020
<p>3 .csv files containing names, years and gender breakdown (m=male, f=female, b=both) of pianists, singers, and composers featured vocal recitals on the three most prestigious stages in Austria, the Musikverein an Konzerthaus in Vienna and at the Salzburger Festpiele between 1970 and 2020.</p> <p>Data was scraped by the author from the Festspiele digital archive (https://archive.salzburgerfestspiele.at/archiv), the concert archives of the Gesellschaft der Musikfreunde in Wien (https://www.musikverein.at/en/archive/) and the Konzerthaus databank (https://konzerthaus.at/datenbanksuche) and is part of an ongoing project to visibilize the gendered nature of collaborative piano at the most prestigious levels. Thanks to Diána Fuchs (https://diana-fuchs.com/) who assisted with the collection of the Musikverein data, with the support of Melanie Unseld at the Department of Musicology and Performance Studies at the mdw - University of Music and Performing Arts Vienna.</p>
