Supplementary 1: Underwater photogrammetry for close-range 3D imaging of dry-sensitive objects: The case study of cephalopod beaks
<ul> <li>Technical advances in 3D imaging have contributed to quantifying and understanding biological variability and complexity. However, small, dry-sensitive objects are not easy to reconstruct using common and easily available techniques such as photogrammetry, surface scanning, or micro-CT scanning. Here we use cephalopod beaks as an example as their size, thickness, transparency, and dry-sensitive nature make them particularly challenging. We developed a new, underwater, photogrammetry protocol in order to add these types of biological structures to the panel of photogrammetric possibilities.</li> <li>We used a camera with a macro-photography mode in a waterproof housing fixed in a tank with clear water. The beak was painted and fixed on a colored rotating support. Three angles of view, two acquisitions, and around 300 pictures per specimen were taken in order to reconstruct a full 3D-model. These models were compared to others obtained with micro-CT scanning to verify their accuracy.</li> <li>The models can be obtained quickly and cheaply compared to micro-CT scanning, and have sufficient precision for quantitative inter-specific morphological analyses. Our work shows that underwater photogrammetry is a fast, non-invasive, efficient, and accurate way to reconstruct 3D models of dry-sensitive objects while conserving their shape. While the reconstruction of the shape is accurate, some internal parts cannot be reconstructed with photogrammetry as they are not visible. In contrast, these structures are visible using reconstructions based on micro-CT scanning. The mean difference between both methods is very small (10<sup>-5</sup> to 10<sup>-4</sup> mm) and is significantly lower than differences between meshes of different individuals.</li> <li>This photogrammetry protocol is portable, easy-to-use, fast, and reproducible. Micro-CT scanning, in contrast, is time-consuming, expensive and non-portable. This protocol can be applied to reconstruct the 3D shape of many other dry-sensitive objects such as shells of shellfish, cartilage, plants and other chitinous materials.</li> </ul>

What is the best fitness measure in wild populations? A case study on the power of short-term fitness proxies to predict reproductive value
<p>Fitness is at the core of evolutionary theory, but it is difficult to measure accurately. One way to measure long-term fitness is by calculating the individual's reproductive value, which represents the expected number of allele copies an individual passes on to distant future generations. However, this metric of fitness is scarcely used because the estimation of individual's reproductive value requires long-term pedigree data, which is rarely available in wild populations where following individuals from birth to death is often impossible. Wild study systems therefore use short-term fitness metrics as proxies, such as the number of offspring produced. This study obtained three frequently used short-term proxies for fitness obtained at different offspring life stages (eggs, hatchlings, fledglings and recruits), and compared their ability to predict reproductive values derived from the genetic pedigree of a wild passerine bird population. We used twenty years of precise field observations and a near-complete genetic pedigree to calculate reproductive success, individual growth rate and de-lifed fitness as lifetime fitness measures, and as annual de-lifed fitness. We compared the power of these metrics to predict reproductive values and lineage survival to the end of the study period. The three short-term fitness proxies predict the reproductive values and lineage survival only when measured at the recruit stage. There were no significant differences between the different fitness proxies at the same offspring stages in predicting the reproductive values and lineage survival. Annual fitness at one year old predicted reproductive values equally well as lifetime de-lifed fitness. However, none of the short-term fitness proxies was strongly associated with the reproductive values. In summary, the commonly short-term fitness proxies capture long-term fitness with intermediate accuracy at best, if measured at recruitment stage. As lifetime fitness measured at recruit stage and annual fitness in the first year of life were the best proxies of long-term fitness, we encourage their future use.</p>

Data from: Principal component analysis as an alternative treatment for morphometric characters: phylogeny of caseids as a case study
In a recent study, the phylogeny of Caseidae (a herbivorous family of Palaeozoic synapsids belonging to the paraphyletic grade known as pelycosaurs) was analysed with a dataset employing more than three hundred continuous morphological characters in an effort to follow the principles of total evidence. Continuous characters are a source of great debate, with disagreements surrounding their suitability for and treatment in phylogenetic analysis. A number of shortcomings were identified in the handling of continuous characters in this study of caseids, including the use of gap weighting to discretize the characters and potential issues with redundancy and character non-independence. Therefore, an alternative treatment for these characters is suggested here. First, rather than using gap weighting, the continuous characters were analysed in the program TNT, in which the raw values can be treated as continuous rather than discrete. Second, prior to the phylogenetic analysis, the continuous characters were subjected to a log-ratio principal component analysis, and then the principal components were included in the character matrix rather than the raw ratios. Analysing the original data in TNT produced little difference in the results, but using the principal components as continuous characters resulted in alternative positions for Caseopsis agilis, Ennatosaurus tecton and Caseoides sanangeloensis. The differences are judged to be due to the reduced redundancy of the characters, the smaller number of principal components not overwhelming the discrete characters and the use of a scaling method which allows principal components with a higher variance to have a greater influence on the analysis. The positions of highly fragmentary fossils depended heavily on the method used to treat the missing characters in the principal component analysis, and so the method proposed here is not recommended for analysing very incomplete taxa.
Analyzing Polyethylene Terephthalate Bottle Waste Technology Using Analytic Hierarchy Process for Developing Countries: A case Study from Indonesia
<p>PET bottle waste is easy to recycle because it is easy to separate, abundant, and competitively priced. Technologies for the treatment of PET bottle waste have been evaluated to date using life cycle assessment (LCA), but this does not take into account all the aspects that policy makers consider necessary to select an acceptable technology. Aspects such as society, economics, policies, and technical applicability need to be considered along with environment and resources consumption to complement the LCA results for PET bottle waste. These aspects were selected as criteria for the Analytical Hierarchy Process (AHP), and stakeholders were invited to make a comparison evaluation of the criteria and sub criteria. Academics were involved to compare the technology option. The results show that society is the highest priority because it is the main actor that ensures the application of the technology, and job creation is the most important indicator for the selection of the technology. After comparing open landfill, sanitary landfill, incineration with energy recovery, pelletizing, glycolysis, and hydrolysis for utilization of PET bottle waste, this study suggests pelletizing as the acceptable technology for Indonesia because pelletizing is supported by social aspects and creates more jobs. This is the first time that a single plastic fraction that is easy to collect and recycle has been studied with AHP. The results show that this type of plastic could also be reused in developing countries through mechanical recycling.</p>
Museomics contributes to the spatiotemporal assessment of genetic diversity and structure in wild and ex situ conservation organisms: a case study of three endangered coastal plants in Japan
<p><span>Understanding </span><span>the extent to which </span><span>genetic diversity of wild populations in ex</span> <span>situ</span><span> conservation can be retained is </span><span>crucial</span><span> for the management of </span><span>such</span><span> populations. Wild individuals collected in the target area in the past </span><span>and</span><span> present can be used to estimate the number of alleles lost over time in wild populations and</span><span> thereby</span><span> the number of alleles whose loss could be </span><span>prevented</span><span> by ex</span> <span>situ</span><span> conservation. </span><span>Here</span><span>, we assessed the genetic diversity of wild and ex</span> <span>situ</span><span> conservation populations of three endangered coastal herb species</span><span>,</span><span> <em>Cirsium maritimum</em> Makino (Asteraceae), <em>Linaria japonica</em> Miq.

We </span><span>incorporated</span><span> the museomics approach, which </span><span>involves conducting</span><span> genetic analyses of museum specimens collected from the targeted wild populations in the past to estimate the temporal transition of genetic diversity in wild populations and the number of alleles maintai</span><span>ned in <em>ex situ</em></span><span> conservation. </span><span>Our </span><span>results </span><span>reveal</span><span> a declining trend in genetic diversity in the wild populations of all </span><span>investigated</span><span> species, although </span><span>this trend is </span><span>not significant.

A critical review of uterine leiomyoma with subsequent recurrence or metastasis: A multicenter study of 62 cases
<p><strong>Aim</strong>: Histopathologic diagnosis of a subset of uterine smooth muscle tumors is challenging. We report a critical review regarding the clinicopathological point of view of 62 cases of subsequently recurred or metastasized leiomyoma.</p> <p><strong>Methods</strong>: Medical records and glass slides of 62 cases of uterine smooth muscle tumor diagnosed as leiomyoma, which subsequently recurred or metastasized, were critically reviewed by pathologists specializing in gynecologic pathology and oncology. </p> <p><strong>Results</strong>: In 47 (75.8%) of 62 cases, the diagnosis of leiomyoma was confirmed, including 11 intravascular leiomyomatosis (IVL) and benign metastasizing leiomyoma (BML). In 29 cases (46.8%) laparoscopic surgery was performed, of which morcellator without a bag was employed in 23 cases. Fifteen cases (24.2%) appeared to be underestimated and were re-classified as smooth muscle tumor of uncertain malignant potential (STUMP), leiomyosarcoma, or other malignant mesenchymal tumors. Recurrences in 7 cases (11.3%) were interpreted to be a malignant transformation, and one Smooth muscle tumor of uncertain malignant potential (STUMP) recurred as STUMP. </p> <p><strong>Conclusion</strong>: The recurrence or metastasis in cases of "leiomyoma" is attributed to iatrogenic or under-evaluation of primary tumors, although a subset of cases is a rare example of biological progression.</p>
