Data from: Movement ecology of brown bears (Ursus arctos) in the Romanian Eastern Carpathians

Ioan Mihai Pop, Leonardo Bereczky, Silviu Chiriac, Ruben Iosif, Andreea Nita, Viorel Dan Popescu & Laurențiu Rozylowicz
Brown bear movement patterns are driven by their opportunistic feeding behaviour, with their complex life history and seasonality playing an important role in habitat selection. Within a large unfragmented forest habitats persisting over decades in the Romanian Carpathians and a prohibitive hunting management during 40 years of communist centralised game management, information about brown bear movements and spatial ecology is lacking. Using data obtained from 13 brown bears fitted with GPS telemetry collars, we estimated...

Data from: Comparative crystallography suggests maniraptoran theropod affinities for latest Cretaceous European ‘geckoid’ eggshell

Seung Choi, Edina Prondvai, Miguel Moreno‐Azanza, Zoltán Csiki‐Sava & Yuong‐Nam Lee
Thin fossil eggshells from Upper Cretaceous deposits of Europe, characterized by nodular ornamentation similar to modern gekkotan eggshells, have mostly been interpreted as gekkotan (=‘geckoid’) in origin. However, in some cases, like the oogenus Pseudogeckoolithus, their theropod affinity was also suggested. The true affinity of these fossil ‘geckoid’ eggshells remained controversial due to the absence of analytical methods effective in identifying genuine gecko eggshells in the fossil record. In this study, we apply electron backscatter...

Data from: A journey on plate tectonics sheds light on European crayfish phylogeography

Lucian Pârvulescu, Jorge L. Pérez-Moreno, Cristian Panaiotu, Lucian Drăguț, Anne Schrimpf, Ioana‐Diana Popovici, Claudia Zaharia, András Weiperth, Blanka Gál, Christoph D. Schubart & Heather Bracken-Grissom
Crayfish can be used as model organisms in phylogeographic and divergence time studies if reliable calibrations are available. This study presents a comprehensive investigation into the phylogeography of the European stone crayfish (Austropotamobius torrentium) and includes samples from previously unstudied sites. Two mitochondrial markers were used to reveal evolutionary relationships among haplogroups throughout the species’ distributional range and to estimate the divergence time by employing both substitution rates and geological calibration methods. Our haplotype network...

Joseph the Good and Saint Joseph. The Surprises of an Ecclesiastic Iconographic Programme in 18th Century Transylvania

Silvia Marin Barutcieff
In the last quarter of the 18th century Transylvania, a Romanian painter proposes a totally unexpected visual discourse in a Greek-Catholic wooden church. The mural painting of the nave contains two portraits of the emperor Joseph II, not placed in the donors’ area. The idea to have a political portrait in a sacred programme represents a novelty for the Greek-Catholic (and also Orthodox) iconographic discourse. This paper aims to analyse the new type of composition...

Bitcoin Awareness, Ownership and Use: 2016–20

Daniela Balutel, Marie-Helene Felt, Gradon Nicholls & Marcel C. Voia
As technology evolves, so does the way Canadians make payments. The Bank of Canada is therefore interested in researching the potential need for a digital alternative to cash. In a 2020 speech, Deputy Governor Tim Lane highlighted two scenarios that could warrant the launch of a central bank digital currency: - a decline in the use of cash - a rise in the use of cryptocurrencies. The Bank conducts regular surveys to monitor trends in...

Data from: First report of ostracods (Crustacea) associated with Bithynian (Anisian, Middle Triassic) Tubiphytes-microbial reef in the North Dobrogean Orogen (Romania)

Marie-Beatrice Forel & Eugen Grădinaru
The Mahmudia Quarry is located in the North Dobrogean Orogen (Romania), representing the western tip of the Palaeotethys-issued Cimmeride Orogenic System. One sample from the Tubiphytes-microbial reef exposed in the quarry yielded an abundant well-preserved ostracod assemblage of Bithynian, early Middle Anisian, Middle Triassic age. We report the occurrence of 56 ostracod species distributed among 23 genera. Ten species are newly described: Acratia caeracella sp. nov., Bairdia mandruella sp. nov., B. liviae sp. nov., Hungarella...

Data from: Rapid genetic and ecological differentiation during the northern range expansion of the venomous yellow sac spider Cheiracanthium punctorium in Europe

Henrik Krehenwinkel, Dennis Rödder, Magdalena Năpăruş-Aljančič & Matjaz Kuntner
Although poleward range expansions are commonly attributed to global change, a complex interaction of ecological and evolutionary factors might contribute to expansion success. Here, we study the expansion of the yellow sac spider Cheiracanthium punctorium, a medically important species in Central Europe. Using microsatellite markers and DNA sequences, morphological and climate niche analyses, we identify factors associated with the spider’s expansion success. Our results indicate that the species’ initial expansion has been triggered by environmental...

Data from: Early spread of COVID-19 in Romania

Marian-Gabriel Hancean, Matjaz Perc & Juergen Lerner
This individual-level dataset describes (a) the early spread of the novel coronavirus (COVID-19) and (b) the first human-to-human transmission networks, in Romania. Specifically, in the first set of data (a), we profile the first 147 cases referring to: whether an individual is an index case, place of residence, sex, age, probable citizenship, probable country and place of infection, arrival date to a Romanian county, COVID-19 confirmation date as well as the sources of information. Also,...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Software for control of autonomous robots using fuzzy logic controllers tuned by genetic algorithms

Corneliu Arsene
This software implements the autonomous control of a robot by using a fuzzy logic controller tuned by a genetic algorithm. The software was written in C programming language for Windows (SDK). A description of the software can be found in the research publication "Arsene, C.T.C., & Zalzala, A.M.S., "Control of autonomous robots using fuzzy logic controllers tuned by genetic algorithms", In Proc Congress on Evolutionary Computation, Vol. 1, pp. 428-35, Washington DC, 1999, IEEE Computer...

Data for: Network of autoscopic hallucinations elicited by intracerebral stimulations of periventricular nodular heterotopia: an SEEG study

Flavius Ionut Bratu, Irina Oane, Andrei Barborica, Cristian Donos, Constantin Pistol, Andrei Daneasa, Camelia Lentoiu & Ioana Mindruta
Periventricular nodular heterotopias (PVNH) are areas of neurons abnormally located in the white matter that might be involved in physiological cortical functions. Autoscopic hallucinations are changes in self-consciousness determined by a mismatch in integration of multiple sensory inputs. Our goal is to highlight the brain network involved in generation of autoscopic hallucination elicited by electrical stimulation of a PVNH in a drug resistant epilepsy patient. Our patient was explored using stereo-electroencephalography with electrodes covering the...

Spectral Study and Molecular Modeling of the Inclusion Complexes of β-Cyclodextrin with Some Phenoxathiin Derivatives

Melania Oana, Mihaela Hillebrand, Aura Tintaru, Daniela Gavriliu & Ovidiu Maior
The inclusion complexes of 3-formyl- (1), 3-acetyl- (2), and 3-carboxyphenoxathiin (3) were investigated by steady-state fluorescence spectroscopy. In the presence of β-cyclodextrin (β-CD), the fluorescence spectra of 1 and 2 point out an enhancement of the emission and a hypsochromic shift of the maxima. In the case of the carboxy derivative the measurements were conducted in buffer solutions, pH = 2.11 and pH = 9.18, to ensure the presence of either the neutral (3a) or...
