PhenoApp: A mobile tool for plant phenotyping to record field and greenhouse observations [version 2; peer review: 2 approved]
With the ongoing cost decrease of genotyping and sequencing technologies, accurate and fast phenotyping remains the bottleneck in the utilizing of plant genetic resources for breeding and breeding research. Although cost-efficient high-throughput phenotyping platforms are emerging for specific traits and/or species, manual phenotyping is still widely used and is a time- and money-consuming step. Approaches that improve data recording, processing or handling are pivotal steps towards the efficient use of genetic resources and are demanded by the research community. Therefore, we developed PhenoApp, an open-source Android app for tablets and smartphones to facilitate the digital recording of phenotypical data in the field and in greenhouses. It is a versatile tool that offers the possibility to fully customize the descriptors/scales for any possible scenario, also in accordance with international information standards such as MIAPPE (Minimum Information About a Plant Phenotyping Experiment) and FAIR (Findable, Accessible, Interoperable, and Reusable) data principles. Furthermore, PhenoApp enables the use of pre-integrated ready-to-use BBCH (Biologische Bundesanstalt für Land- und Forstwirtschaft, Bundessortenamt und CHemische Industrie) scales for apple, cereals, grapevine, maize, potato, rapeseed and rice. Additional BBCH scales can easily be added. The simple and adaptable structure of input and output files enables an easy data handling by either spreadsheet software or even the integration in the workflow of laboratory information management systems (LIMS). PhenoApp is therefore a decisive contribution to increase efficiency of digital data acquisition in genebank management but also contributes to breeding and breeding research by accelerating the labour intensive and time-consuming acquisition of phenotyping data
AVONET: morphological, ecological and geographical data for all birds
Functional traits offer a rich quantitative framework for developing and testing theories in evolutionary biology, ecology and ecosystem science. However, the potential of functional traits to drive theoretical advances and refine models of global change can only be fully realised when species‐level information is complete. Here we present the AVONET dataset containing comprehensive functional trait data for all birds, including six ecological variables, 11 continuous morphological traits, and information on range size and location. Raw morphological measurements are presented from 90,020 individuals of 11,009 extant bird species sampled from 181 countries. These data are also summarised as species averages in three taxonomic formats, allowing integration with a global phylogeny, geographical range maps, IUCN Red List data and the eBird citizen science database. The AVONET dataset provides the most detailed picture of continuous trait variation for any major radiation of organisms, offering a global template for testing hypotheses and exploring the evolutionary origins, structure and functioning of biodiversity
Double resonance rotational spectroscopy of CH
Context. Deuterated forms of CH3+ are thought to be responsible for deuterium enrichment in lukewarm astronomical environments. There is no unambiguous detection of CH2D+ in space to date.
Aims. Four submillimetre rotational lines of CH2D+ are documented in the literature. Our aim is to present a complete dataset of highly resolved rotational lines, including millimetre (mm) lines needed for a potential detection.
Methods. We used a low-temperature ion trap and applied a novel IR–mm-wave double resonance method to measure the rotational lines of CH2D+.
Results. We measured 21 low-lying (J ≤ 4) rotational transitions of CH2D+ between 23 GHz and 1.1 THz with accuracies close to 2 ppb
Vollwandresektion eines Pylorusdrüsenadenoms im proximalen Duodenum bei einem 67-jährigen Patienten mit attenuierter Polyposis coli
Background: Pyloric gland adenomas (PGAs) are very rare and underdiagnosed, mostly be founded in the stomach. Similar to colorectal adenomas they have a high risk of malignant transformation to adenocarcinoma up to 12-47 %. Endoscopic resections in the duodenum harbor a significant risk of complications. EMR is the current standard technique for treatment of duodenal non-ampullary adenomas. Complete resection rates are considerably high at about 90 %. Adverse events as bleeding was reported up to 25 %. ESD is not recommended for resection of duodenal lesions since the perforation rate may be as high as 35 %. Use of EFTR in the duodenum are limited to a single case study of 20 patients.
Case: A 67 year old patient with attenuated polyposis coli presented for screening. Gastroscopy showed a 20 mm large, non-ampullary lesions in the proximal duodenum (pars I). The margins of the duodenal lesions were marked with a high-frequency (HF) probe. An integrated balloon dilatation (20 mm) of the upper esophageal sphincter and the pylorus was performed to facilitate advancing of the gastroduodenal FTRD® (Ovesco Endoscopy AG). After pulling the duodenal lesion into the cap with a grasper the FTRD clip was deployed and the lesion immediately resected with the preloaded snare. A single-shot antibiotic prophylaxis with 2 g ceftriaxone i. v. was administered during the intervention. Second-look endoscopy was scheduled 24 h after resection. The resectat showed histologically a gastric type adenoma of 18 mm in the proximal duodenum (immunohistochemistry positive for Mucin-1, Mucin-5, Mib 1).
Conclusion: Herein we present the first case of duodenal EFTR in a patient with attenuated FAP and a PGA. There are currently no specific guidelines for the removal and surveillance. ASGE recommends resection and surveillance endoscopy at 3-5 years interval

A8_FI_birds
Current and projected future functional identity, i.e. mean bill width, mean bill length, mean Kipp’s index and mean body mass of frugivorous bird communities along an elevational gradient in the Manu National Park in south-east Peru. Mean values are computed based on the z-transformed raw traits (i.e. traits have been standardized to a mean of zero and a standard deviation of one according to the entire species pool). Projections were done according to five general circulation models (CCSM4, HadGEM2-ES, MIROC 5, MRI-CGCM and NorESM), representative concentration pathway 8.5 and the year 2080. Furthermore, we applied three vertical dispersal scenarios (range contraction, range expansion and range shift). For details on the projections, please read the methods in the published article associated with this data set
A2_Elevation_birds
Current minimum and maximum elevation and elevational range extents of 217 frugivorous bird species from the Manu National Park in south-east Peru (Dehling et al., 2013; Merkord, 2010; Walker et al., 2006). Further given are projected species-specific mean vertical distances. Species-specific mean vertical distances were projected according to five general circulation models (CCSM4, HadGEM2-ES, MIROC 5, MRI-CGCM and NorESM), representative concentration pathway 8.5 and the year 2080
