Article Reference Colonization of artificial islands in the Kazakh sector of the Caspian Sea by the aquatic snake Natrix tessellata (Squamata: Natricidae)
We report the colonization by the aquatic Dice snake Natrix tessellata of five artificial islands (A Island, D Island, DC 05, EPC 03 and EPC 04), built in the 2000s to house oil industry activities in the Kazakh sector of the Caspian Sea, western Kazakhstan. We discuss possible modes of colonization (e.g., accidental transport by boat originating from the Bautino harbor in Mangystau Region; active swimming from the coast). We present several observations of predation on fish (Cyprinidae: Carassius auratus; Gobiidae: Neogobius caspius, N. fluviatilis and N. melanostomus) and on the Laughing frog (Ranidae: Pelophylax ridibundus).

Article Reference Combined High-Throughput Imaging and Sequencing: Addressing the collections on demand requirement in SYNTHESYS+ project
Imagine you are a scientist, working on collections. You have your pet taxon and you need information which is distributed in a number of books and publications but also in the specimens deposited in$~$Museums or Herbaria. Instead of paying visits to these establishments, around the world, you wish there was a means to transform all the information you need into a digitized form of the physical objects, you can reach from the screen of your laptop, tablet or cell phone. You dream you were able to watch, inspect and even dissect the type material you need online but also to compare it with others they way sequences are blasted against large databases, these days. You plan to make global research on this taxon and try to derive patterns from both the molecular and organismal level of the biological organization and to link the patterns resulting to the drivers of change for this taxon.$~$This is the vision of the Virtual Museum of Natural History and one of the ways to achieve this vision is to address the “collections on demand” requirement. One of the possible means to address this requirement is the digitization through the use of the micro-ct technology. The micro-CT virtual laboratory (vLab), developed by LifeWatchGreece research infrastructure (RI), makes it possible the online exploration and dissemination of micro-CT datasets, which are only rarely made available to the public due to their large size and a lack of dedicated online platforms for the interactive manipulation of 3D data. This presentation shows the development of such a “collections on demand” function, implemented by the SYNTHESYS+ project (DiSSCo RI), which combines such high-throughput technologies, that is micro-ct and genomics, to address the scientific communityʼs requirements. We show that this approach to combine patterns deriving from the application of novel techniques, which represent different kinds of observations is possible and we propose certain case studies as examples. The innovation aspects of this function include: Expansion and development of cost models for Collections on Demand; Development of standards and guidelines for exchange of collection-derived imaging data; Construction of new data pipelines and standard workflows, enabling access to complex digital content such as 3D scans; Development of novel molecular lab protocols, workflows and informatics pipelines, to enable large scale; DNA sequencing of NH collections.

Article Reference Combined land surface emissivity and temperature estimation from Landsat 8 OLI and TIRS
Remote sensing of Land Surface Temperature (LST) generally requires atmospheric parameters and the emissivity (∊) of the target to be estimated. The atmospheric up- and downwelling radiances and transmittance can be accurately modelled using radiative transfer models and profiles of relative humidity and temperature, either measured by radiosonde probes or retrieved from assimilating weather models. The estimation of ∊ is a large source of uncertainty in the resulting LST product, and there are various approaches using multi-angle observations, multispectral optical or multispectral thermal infrared imagery. In this paper, the estimation of LST from the Thermal InfraRed Sensor (TIRS) on board Landsat 8 is evaluated using more than 6 years of in situ temperature measurements from a network of 14 Autonomous Weather Stations (AWS) in Belgium. ∊ is estimated from concomitant atmospherically corrected imagery from the Operational Land Imager (OLI) using two new neural network approaches trained on ECOSTRESS spectra, and an established NDVI based method. Results are compared to using ∊=1 and the ASTER Global Emissivity Dataset. LST retrievals from L8/TIRS perform well for all emissivity data sources for 500 matchups with AWS subsoil temperature measurements: Mean Differences 0.8–3.7 K and unbiased Root Mean Squared Differences of 2.9–3.5 K for both B10 and B11. The use of unity emissivity gives the best results in terms of MD (0.8 K) and unb-RMSD (3 K). Similar ranges of unb-RMSD are found for 500 matchups with broadband radiometer temperatures (2.6–3.1 K), that have lower absolute MD values (−2.2–0.6 K). For the radiometer temperatures, both the neural net approaches gave lowest MD, in the best case ±0.1 K. The present investigation can hence recommend the neural nets to derive ∊ for the retrieval of LST over the AWS in Belgium. Using published matchup results from other authors however, no single source of ∊ data performed better than ∊=1, but this could be due to their low number of matchups. Further efforts for estimating representative pixel average emissivities are needed, and establishing a denser in situ measurement network over varied land use, with rather homogeneous land cover within a TIRS pixel, may aid further validation of a per pixel and per scene ∊ estimates from multispectral imagery. AWS data seems valuable for evaluation of satellite LST, with the advantage of a much lower cost and higher potential matchup density compared to conventional radiometers.

Article Reference Comparative Anatomy of Mandibular Neurovascular Canals in Modern Human and Great Apes: A Pilot Study With Cone Beam Computed Tomography
The aim of the present study was to compare mandibular neurovascular canal anatomy in human and great apes by using cone beam computed tomography (CBCT). The anatomical variability of mandibular neurovascular canals (mandibular, incisive and lingual canals) of 129 modern humans and great apes (Homo, Pan and Gorilla) were analyzed by linear measurements on CBCT images. The Kruskal-Wallis non-parametric test and Dunn’s all pairs for joint ranks were applied to compare the variability of mandibular canals among these groups. Human, Chimpanzee and Gorilla groups showed significant differences in the dimensions of the mandibular canal, mental foramen, incisive canal, lingual canal and anterior mandibular bone width. Bifid mandibular canals and anterior loops were the anatomical variations most frequently observed in the Gorilla. Humans had a larger mental foramen and a distinctive incisive canal. The latter could not be identified in the Gorilla group. The variability in the anatomy within mandibles of human and non-human primates, shows different forms in the neurovascular structures. In comparison to the mandible of great apes, the incisive canal is suggested to be a feature unique to the human mandible.
