Golden jackal, a natural disperser or an invasive alien species in Slovakia? A summary within European context
Authors: Urban Peter , Guimarães Nuno , Bučko Jozef 
Published: November 2020

Abstract
This summary provides an overview of the golden jackal (Canis aureus) categorization in Europe with particular focus on its presence in Slovakia. The distribution range of this species in Europe has been expanding in recent decades. Currently, European population is in constant and fast increase, widening their ranges towards Central and Eastern Europe and more recently in some western countries. All over Europe, the categorization of the golden jackal status is discussed with some controversial. A recent genetic study helped to determine that golden jackals do not meet the established three criteria, which categorize a species as an invasive alien species. In Slovakia, golden jackals’ numbers grown considerably in the last decade and with an increasing of their distribution through the country it became a permanent species of the Slovak fauna. The only internal status is the hunting Act no. 274/2009, which classifies it as, game species. The fast adaptation and dispersion through Slovakia can be considered similar to the behaviour of an invasive species, as suggested in previous studies in Hungary. Based on widely accepted definitions, agreed under international legal instruments, it is quite clear that the term ‘Invasive Alien Species’ only encompasses non-native species specifically introduced by humans (intentionally or accidentally). Following this Invasive Alien Species terminology, golden jackals cannot be categorized as such in Slovakia. The natural expansion, the growing ranges, and the increase in numbers of the golden jackal in Slovakia in the last decades points to a need to improve the knowledge of the species.
Invasions of alien woody plant taxa across a cluster of villages neighbouring the Mlyňany Arboretum (SW Slovakia)

Published: November 2020

Abstract
Ornamental plantations in cities and particularly botanical gardens and arboreta are rich sources of alien flora. Mlyňany Arboretum, established in 1892, cultivates 1049 non-native woody plant species on the area of 67 ha. In this work we answered following questions: 1. How many taxa are spontaneously spreading in the arboretum and how is the spreading intensity related to their ecological demands and reproduction traits? 2. How many taxa appear behind the fence? 3. How far from the arboretum they can get? 4. Do private gardens and historical aristocratic park in the studied village cluster contribute to species escapes from culture? 5. Which from the widely spread taxa can represent future risk of invasiveness on the national level? We found that about one tenth of taxa spread across the arboretum (particularly Cotoneaster spp., Prunus laurocerasus, P. serotina and Quercus rubra) and number of their seedlings corresponded only with the mother plant number. Almost one third of these species left the arboretum and their seedlings were observed in distance up to 500 m from the village (mainly Mahonia aquifolium, P. serotina). Private gardens were a large source of Juglans regia seedlings, frequency of which decreased with the distance from villages (no species escaped from the historical park). Weed risk assessment revealed potential invasion danger only for Amorpha fruticosa.
Known and predicted impacts of the invasive oak lace bug (Corythucha arcuata) in European oak ecosystems – a review
Authors: Paulin Márton , Hirka Anikó , Eötvös Csaba Béla , Gáspár Csaba , Fürjes-Mikó Ágnes , Csóka György 
Published: November 2020

Abstract
The North American oak lace bug (OLB, Corythucha arcuata) was first found in Europe in northern Italy in 2000, and up to 2019 it was recorded in 20 countries. Almost all Eurasian deciduous oak species are suitable hosts and the species can also feed on many other woody plants. At least 30 million hectares of oak forests provide suitable hosts for the OLB, meaning that the lack of suitable hosts will not restrict its further spread. Detailed studies on the long-term impact of the species are not yet available but there are many good reasons to assume that it poses multiple threats to oaks and oak ecosystems. In the long term, it may have negative effects on oak health, growth, and acorn crops. Many of other oak-associated species will likely also be negatively affected. So far, no effective and environmentally tolerable large scale control method is known for OLB.
Appearance of oak lace bug (Corythucha arcuata Say, 1832) on sweet chestnut in Hungary (Heteroptera: Tingidae)

Published: November 2020

Abstract
Oak lace bug (Corythucha arcuata) has caused increasing damage throughout Europe since its appearance in 2000. In Hungary, it has become a dangerous pest of Quercus species in recent years. They frequently appear on ornamental and fruit trees, either, but this type of damage is not significant. Castanea species are known as their common host plants in their native area, but in Europe, it was detected only in Bulgaria. In this paper, we provide the first record of oak lace bug on sweet chestnut (C. sativa) in Hungary, which represents only the second European data on Castanea species. The pest was found in Debrecen, East Hungary.
Urban ecosystems as locations of distribution of alien aquatic plants
Authors: Prokopuk Mariana , Zub Lesya 
Published: November 2020

Abstract
Peculiarities of alien macrophytes invasions into aquatic ecosystems located at urban landscapes were investigated on an example of water bodies, rivers and streams located within the Kyiv City (Ukraine). There have been recognised seven species of alien aquatic macrophytes established at the territory of Kyiv City, representing 11% of the hydrophilic flora of the city. The representatives of the recent invasions Egeria densa, Elodea nuttallii and Pistia stratiotes in comparison with Elodea canadensis were characterized by a wider ecological valence concerning the contents of nitrogen compounds in water. Significant variability of morphometric parameters of coenopopulations of alien species formed in different environmental conditions was recognised. There was observed that the individuals of Pistia stratiotes from eutrophic water bodies formed significantly larger surface organs, and the individuals from meso-eutrophic reservoir had a larger number of leaves in the rosette, and more numerous and longer roots. The alien macrophytes species dwelling in the water bodies of the city were characterized by wide ecological amplitudes, high stress tolerance, high reproduction rate, high naturalization degree, allowing these species to use the resources of their new environment inaccessible for the local species and significantly affecting the ecosystem homeostasis and transformation.
Suppressiveness of soil amendments with pelleted plant materials on the root-knot nematode Meloidogyne incognita
Authors: D’Addabbo T. , Migunova V. D. , Renčo M. , Sasanelli N. 
Published: November 2020

Summary
Soil treatments with formulated plant biomasses or waste materials can be an effective alternative to green manure crops for a sustainable management of root-knot nematode infestations. The suppressive performance of soil amendments with three commercial formulations of defatted seed meal from Brassica carinata, dry biomass of Medicago sativa and pressed pulp from Beta vulgaris was comparatively evaluated on the root knot nematode Meloidogyne incognita both on potted and field tomato (cv. Regina) trials. Products were applied at rates of 10, 20, 30 or 40 g/kg and 20 and 40 T/ ha soil in pots and field, respectively. Soil non treated or treated with the nematicide Oxamyl were used as controls in both experiments. Amendments in potted soil significantly reduced M. incognita infestation on tomato roots compared to both the untreated control and treatment with Oxamyl, also increasing tomato plant growth up to the 30 g/kg soil rate. At the end of the field tomato crop, soil population density of M. incognita resulted significantly reduced by all the tested treatments, whereas tomato yield was significantly higher than the untreated control only at the lowest amendment rate. Soil amendments with the materials tested in this study demonstrated to be a potential additional tool for a satisfactory and safe management of root-knot nematodes.
The effects of seasonality and group size on fecal egg counts in wild Przewalski’s horses (Equus ferus przewalskii, Poljakov, 1881) in the Chernobyl Exclusion Zone, Ukraine during 2014 – 2018
Authors: Slivinska K. , Klich D. , Yasynetska N. , Żygowska M. 
Published: November 2020

Summary
The aim of this study was to investigate the difference in Fecal Egg Counts (FEC) with regard to group size, age, sex and body condition of wild free-roaming Przewalski’s horses in the Chernobyl Exclusion Zone (Ukraine), across different seasons, over a five-year period (2014 – 2018). We hypothesized that horses from larger group sizes would have higher faecal egg counts (FECs). The relationship between FECs and the year and season of sample collection, and age, sex and group size of the horses was analyzed. Generalized linear model using positive strongylid FEC`s as a variable response, was used to investigate the differences in FECs between the groups.
Nematode (Strondylidae, Parascaris spp., Habronematidae) and cestode (Anoplocephalidae) eggs were also identified. Stronglyids were the most prevalent helminth egg, and had the highest FECs.
The model for egg counts of strongylids showed that season and group size of horses were statistically significant. Presence of strongylid eggs was not dependent on age and sex of horses. We suggest that this could be a result of parasite transmission between individuals and groups in places were animals aggregate around water sources or collective farms.
Results obtained in this current study broaden the knowledge of gastrointestinal parasites in free-roaming horses under wild natural conditions.
Informal work along the business cycle: evidence from Argentina
Authors: Albertini Julien , Poirier Arthur , Sopraseuth Thepthida 
Published: November 2020

Abstract
This article sheds light on the dynamics of the Argentine labor market, using quarterly data from the Argentine Labor Force Survey for the period 2003Q3 to 2020Q1. We examine quarterly transition rates in a four-state model with formal employment, informal employment, unemployment, and nonparticipation. We compute the contribution of each transition rate to fluctuations in unemployment and informality rates. We identify five stylized facts: (i) Nearly 40% of the fluctuations in the unemployment rate involves unemployment ins and outs from/to informal jobs. (ii) More than 40% of the fluctuations in informality rate are driven by the variance of the formalization rate (transition from informal to formal employment). (iii) Non-participation matters for the understanding of unemployment volatility but also for the comprehension of the volatility on informality. (iv) Regarding gender differences: transition involving non-participation matters more in the variance of female unemployment and informality rates than for their male counterparts. (v) The informal sector plays an important role as a stepping stone to formal jobs for both men and women. Our article provides empirical targets to discipline theoretical modeling of labor market dynamics with a sizeable shadow economy.
Heterogeneous effects of minimum wage on labor market outcomes: A case study from Turkey
Authors: Işık Enes , Orhangazi Özgür , Tekgüç Hasan 
Published: November 2020

Abstract
We assess the effects of a sharp minimum wage increase on wages, informality, and employment in Turkey, a large developing economy with one of the highest minimum wage-to-average wage ratios among OECD countries and widespread discrepancies between labor market outcomes of women and of men. We look at the quasi-experimental 2016 minimum wage increase and pay attention to identifying information coming from demographic groups. We find that the increase in the minimum wage had an economically substantial and statistically significant positive impact on wages. Despite the positive wage effects of the increase, we find no negative employment effects. However, we show that the minimum wage increase may have caused an increase in the share of informal employment among workers with less than tertiary education, especially for such workers working for small firms.

Authors: Osadume Richard , Blessing Uzoma, C. 
Published: November 2020

Abstract
This paper investigates Maritime trade and economic development: A granger causality and Bound test approach. Most scholars believe that maritime trade openness will transform economy into a developed nation while some disagree. The main objective of this research is to examine the relationship between maritime trade and economic development; specifically, to ascertain whether maritime trade granger-causes economic development; and to determine whether there is a co-integration between maritime trade and economic development. The study used secondary data obtained from the Central Bank of Nigeria and the United Nations development Programme, and tested the effect of independent variables on a dependent variable. The variables were tested using Stationarity, heteroskedasticity, Ramsey reset, granger-causality and ARDL Bounds test at the 5% level of significance. The findings revealed that maritime trade proxy by trade openness had a significant effect on economic development captured by HDI and the ARDL Bound test showed a significant effect of trade openness on economic development. The study concludes that maritime trade granger-causes economic development with a Bi-directional causal relationship and significant co-integration exists between them; and recommends among others the provision of conducive environment and cheap funding by the government to encourage the growth of maritime trade.

Published: November 2020

Abstract
The article presents the general characteristics of road transport safety in Poland over the years 2009-2019. The key objective of this study was to investigate the main factors of road accidents in Poland. Up till now, the number of road accidents has been analysed in detail on the basis of data on collisions from rear, side and frontal perspective. Moreover, in the article, statistics regarding the number of perpetrators of accidents by gender and age are summarized, as well as dynamics aspects of changes related to new passenger vehicles and trucks in Poland in 2009-2019 are indicated. As a result, the intensity of rear collisions rather than frontal collisions is apparent. Hence, an inconspicuous rear collision by not braking a speeding vehicle carries a risk of the upper cervical spine.

Published: November 2020

Abstract
The capital of Romania is the main railway hub of the country. As such, the railway network around the capital is quite extensive, with main cities around it being directly connected by rail. Despite this, there are no regular train services for commuters, similar to other large European cities. This paper aims to analyze the current state of railway passenger transport in the region surrounding Bucharest, to highlight the weaknesses of the network and to present a guideline for the implementation of an efficient commuter service. 100 stations in and around the city were evaluated with regard to their degree of accessibility (DoA), defined as the location of the station relative to the nearest settlement. Train frequency, travel times and journey costs were determined for each line originating in Bucharest. These variables were compared to their road equivalents to highlight the differences between these two modes of transport. Low train frequency and the remoteness of many stations were determined to be the main obstacles in establishing an appropriate commuter service. Reworking future timetables to prioritize commuter trains is proposed as a short-term solution, while line improvements and better integration with existing public transport are set as priorities.
Municipal splits and hidden amalgamations in Hungary
Authors: Dobos Gábor 
Published: November 2020

Abstract
In 1990, a decentralized local government system was introduced in Hungary. One of the main issues of the system was fragmentation at local level. This paper examines the attempts made by the central government to deal with this issue in the last thirty years. First, the study analyses the municipal splits and maps the dynamics, the reasons, and the environmental and political factors affecting these secessions. Second, it examines the government’s attempts at reform to reduce the effects of fragmentation.
The paper argues that the Fidesz-KDNP electoral victory in 2010 was a milestone in the handling of territorial issues: municipal splits became virtually impossible with the new regulation of the secession process, and de facto territorial consolidation reform was carried out through alteration of the local electoral system and functional rescaling and merging of the mayors’ offices.
Using GMT for 2D and 3D Modeling of the Ryukyu Trench Topography, Pacific Ocean
Authors: Lemenkova Polina 
Published: November 2020

Abstract
This research focuses on the 2D and 3D geospatial analysis of the Ryukyu Trench, a deep-sea trench located in the western Pacific Ocean between Japan and Taiwan. The aim of the research is to visualize regional differences in the topography of the southern (S) and northern (N) parts of the trench. Technically, the methodology is based on using the Generic Mapping Tools (GMT) scripting toolset, for modelling the General Bathymetric Chart of the Oceans (GEBCO), and Earth Topography and Bathymetry dataset (ETOPO1) raster grids. The results demonstrated topographic differences in the two segments. The most frequent depths lie between −5,000 and −6,000 m. The N part has steeper gradient slopes and deeper bathymetry. Of the depth differences >−6,000 m, S has nine values with depths >−6,800 m while N shows 123 records (max −7,460 m). The submarine terraces of S have gentler slopes compared with the N segment. The technical approach presents GMT-based 2D and 3D cartographic modelling aimed at visualizing regional variations of the seafloor topography.

Published: November 2020

Abstract
The purpose of the present investigation was to prepare pH-sensitive hydrogels from photo-crosslinked poly(ethylene glycol) diacrylate (PEG-DA). Rutile titanium dioxide (TiO2) was employed to modify the PEG-DA hydrogels. The rutile titanium dioxide (TiO2) nanoparticles were prepared by direct oxidation of titanium in the presence of polyethylene glycol (PEG) at high temperature. The nanoparticles were characterized by FT-IR, XRD and SEM. The influence of experimental conditions, such as pH, type and amount of photoinitiators on the release profiles of donepezil hydrochloride (active pharmaceutical ingredient for Alzheimer disease) from modified PEG-DA hydrogels, was investigated. The drug release processes were analyzed kinetically using zero-order, first-order, Hixson-Crowell and Peppas models.
Candidate proteomic biomarkers in systemic sclerosis discovered using mass-spectrometry: an update of a systematic review (2014–2020)

Published: November 2020

Abstract

Background. Systemic sclerosis (Ssc) is an autoimmune disease characterized by graduate cutaneous and tissue fibrosis development and irreversible fibroproliferative vascular changes.
The aim of the current systematic review was to update the list of proteomic candidate biomarkers identified from Ssc samples with mass spectrometry techniques.

Methods. Medline and Scopus databases were searched on 1st September 2020. Relevant articles were searched from March 2014 until September 2020. Two independent reviewers evaluated the retrieved articles.

Results. From a total of 97 articles, 9 articles were included in the final analysis summarizing 539 candidate proteomic biomarkers from various samples from Ssc patients (a larger number compared to the previous systematic review). Most biomarkers were identified from cutaneous biopsies. Only 5 articles included a validation step of the findings with only 13 biomarkers being validated.

Conclusions. Although many candidate biomarkers were additionally identified, independent validation studies are needed in order to evaluate the importance of these biomarkers for Ssc patients.
