Woodpecker drum evolution: an analysis of covariation in elements of a multicomponent acoustic display among and within species
<p>Multicomponent signals are found throughout the animal kingdom, but how these elaborate displays evolve and diversify is still unclear. Here, we explore the evolution of the woodpecker drum display. Two components of this territorial, sexually selected signal, drum speed and drum length, are used by territory holders to assess the threat level of an intruding drummer. We explore the coevolution of these display components both among and within species. Among species, we find evidence for strong coevolution of drum speed and length. Within species, we find that drum speed and length vary largely independent of each other. However, in some species, there is evidence of covariation in certain portions of the drum length distribution. The observed differences in component covariation at the macro- and microevolutionary scales highlights the importance of studying signal structure both among and within species. In all cases of covariation at both evolutionary scales, the relationship between drum speed and length is positive, indicating mutual elaboration of display components, and not a performance trade-off.</p>

2 PREHEALING: Design of concrete precast elements incorporating sustainable strategies for self-healing to increase their service life. Concrete analysis
<div>This project addresses the analysis of the performance of concrete with internal curing aggregates (ICA), low-clinker cementitious materials, and steel fibres for use in real applications in the precast industry. A total of eight mixes were designed: 100C, 60C25BA15M (where BA denotes forestry biomass and M denotes metakaolin), 60C25LF15M (with LF as limestone filler and M as metakaolin), 100C-30CBA (where CBA denotes porous aggregate from coal ash), 60C25BA15M-30CBA, 60C25LF15M-30CBA, 60C25BA15M-30CBA-F (where F denotes fibres), and 60C25LF15M-30CBA-F. Two different curing conditions were analysed (standard water curing and humidity/drying cycles), assessing the recovery of mechanical properties and four curing conditions for impermeability recovery: i) carbonated water (CW), ii) immersion/drying cycles in carbonated water (CW wet-dry), iii) tap water (TW), and iv) immersion/drying cycles in tap water (TW wet-dry).</div> <div> </div> <div>This section includes the results of all tests conducted during the experimental campaign, divided into two files:</div> <div> </div> <div> <ul> <li>01_Permeability Test.zip: <br>The attached files contain the results of the permeability tests conducted on cracks opened through the indirect tensile test on cylindrical discs. Permeability tests were initially performed after the crack was opened and then following a self-healing process under four curing conditions: i) carbonated water (CW), ii) immersion/drying cycles in carbonated water (CW wet-dry), iii) tap water (TW), and iv) immersion/drying cycles in tap water (TW wet-dry), at two exposure times: 28 and 90 days.</li> </ul> </div> <div> <ul> <li>02_Mechanical Recovery.zip:<br>The attached files contain the results of the three-point bending test, including crack opening measurements and the force applied at each interval. The cracks were reopened after a curing period in continuous tap water and in immersion/drying cycles. After a period of 28 and 90 days, the cracks were reopened to calculate the mechanical recovery during the self-healing period. The attached files contain all test results conducted during both phases.</li> </ul> </div>
Unraveling the myotis norass: Ultraconserved-element analysis reveals introgression, cryptic diversity, and taxonomic trouble
<p>Using sequences from 2615 UCE loci and multiple methodologies we inferred phylogenies for the largest genetic dataset of New World Myotis to date. The resulting phylogenetic trees were populated with short branch lengths and widespread conflict, hallmarks consistent with rapid adaptive radiations. The degree of conflict observed in Myotis has likely contributed to difficulties disentangling deeper evolutionary relationships. Unlike earlier phylogenies based on 1-2 gene sequences, this UCE dataset places M. brandtii outside the New World clades. Introgression testing of a small subset of our samples revealed evidence of historical but not contemporary gene flow, suggesting that hybridization occurs less frequently in the Neotropics than in the Nearctic. We identified several instances of cryptic lineages within described species as well as several instances of potential taxonomic over-splitting. Evidence from Central and South American localities suggests that diversity in those regions is not fully characterized. In light of the accumulated evidence of the evolutionary complexity in Myotis and our survey of the taxonomic implications from our phylogenies it is apparent that the definition of species and regime of species delimitation need to be re-evaluated for Myotis. This will require substantial collaboration and sample sharing between geneticists and taxonomists to build a system that is both robust and applicable in a genus as diverse as Myotis.</p>
Massively Parallel Reporter Assays for High-Throughput In Vivo Analysis of Cis-Regulatory Elements
<p>A library of 50 enhancers, each tested in three different lengths and with two different promoters (300 combinations), was packaged into AAV9 and delivered to newborn mice. Enhancers were selected from the VISTA Enhancer Browser of transgenic reporter data, and included 25 candidates active in the embryonic myocardium and 25 negative control candidates active in embryonic endothelium but not in myocardium. In the heart, AAV9 selectively transduces cardiomyocytes. After collecting ventricles at P28, the reporter transcripts were sequenced, and the frequency of each barcode was compared to its frequency in the viral pool DNA.</p> <p>Here we provide fastq files for each sample, an Excel spreadsheet (MPRA-Metadata.xls) containing annotation, and an Excel spreadsheet (MPRA-counts.xlsx) containing extracted barcode counts for each enhancer, as well as additional annotation and calculated enhancer activity.</p>
