Seasonality and habitat preferences of dung beetles (Coleoptera: Geotrupidae) attracted to moose Alces alces L. dung in the Kampinos National Park
Authors: Marczak Dawid , Mroczyński Radosław 
Published: November 2019

Abstract
Dung beetles (Coleoptera: Geotrupidae) are an extremely important element of many ecosystems. Their activity allows the incorporation of mineral compounds trapped in faeces into the nutrient cycle.	Seasonality and habitat preferences are the most important factors shaping the beetle communities inhabiting dung. The present study compares beetle communities inhabiting moose dung Alces alces L. in various forest ecosystems quantitatively and qualitatively. Due to the beetle seasonality, field work was performed from the beginning of March until the end of October 2017 in three habitats: coniferous forest, oak-hornbeam forest and alder forest. The dung beetles were collected using three Barber traps on each site baited with moose dung (80 g ± 10 g) and the traps were emptied as well as rebaited every 15 days. Altogether, 2330 specimen of dung beetles representing three species were collected: Anoplotrupes stercorosus (2088), Trypocopris vernalis (154) and Geotrupes stercorarius (88). These three species were found in all of the studied habitats. The largest total number of individuals was captured in the alder forest (1132 individuals), followed by the broadleaved forest (712) and the smallest number was captured in the coniferous forest (486). In terms of individuals caught, each species was statistically significantly different between the habitats. The largest number of A. stercorosus was captured in the alder forest, followed by the broadleaved forest and the smallest number was caught in the coniferous forest. however, the reverse was observed in the case of T. vernalis and G. stercorarius, where the most individuals were caught in the coniferous forest, and fewer in the broadleaved and alder forests. This is most likely due to the various habitat preferences of each individual species. Furthermore, the seasonal dynamics of this beetle family showed some differences between habitats. These differences most probably resulted from different microclimatic and humidity conditions.

Published: November 2019

AbstractThis study explores the use of fully automatic monitoring system of peat moss substrate moisture under pine seedlings at Rudy Raciborskie forest nursery in the Silesian Upland. A brand new multipoint system for this study was created. The multichannel electronic recorder MPI-DN Metronic was the main part of the project. Twelve HD3910.2 probes (three electrodes) for volumetric water content measurement were used in a distributed configuration. Modbus RTU protocols were used for data transmission and the results were archived into an internal memory. One probe delivers 1440 measurements a day. Based on the average substrate moisture data from the field, the recorder controls the watering system according to the precisely defined parameters. Proper placement of sensors in the field allows for accurate analysis of the temporal and spatial variability of peat moss substrate moisture. Results of the statistical analysis have confirmed that the peat moss moisture is significantly differentiated within the homogeneous production field of the forest seedlings. The study findings suggest that irrigation systems should be adapted to specific situation of substrate moisture at the nursery surfaces aimed at optimised water management.
Denoting the intensity of soil biochemical transition according to stand species composition
Authors: Olszowska Grażyna 
Published: November 2019

Abstract
The aim of this study was to denote biochemical soil activity in pure Scots pine, Norway spruce, silver fir, European larch, European beech and oak stands as well as in mixed fir-pine, beech-pine and fir-beech forests growing on a fertile fresh mixed deciduous site. The field work was carried out in the following Forest Districts: Nowe Ramuki (Mazursko-Podlaska forest region), Płońsk, Jabłonna, Brzeziny Siedlce, Grójec (Mazowiecko-Podlaska forest region) and Skarżysko, Ostrowiec and Marcule (Małopolska forest region). In 2015–2017, sample plots were assigned and chemical as well as soil enzyme activity measurements were made in each forest stand. Samples were taken from the organic (O) and humus (A) layers and for both the acidity (in 1M KCl), content of nitrogen, carbon, sum of exchangeable alkaline cations and hydrolytic acidity were determined. The investigation of soil enzymes included the measurements of urease, asparginase, acid phosphatase and dehydrogenase activity. Coniferous trees, especially fir, spruce or larch, and mixed fir-beech and pine-beech stands were observed to have a very positive influence on the biochemical soil properties. The highest activity of dehydrogenase was observed in soils of spruce and mixed fir-beech stands, whereas it was lower in soils of beech and pine stands, and the lowest in oak stands. Oak stands were furthermore characterized by the lowest soil acidity, lowest concentration of alkaline cations, the lowest nitrogen and carbon content as well as the smallest C/N ratio. In overall, soil enzyme activity showed a significant correlation with chemical soil parameters.
Forest policy goals in Poland in light of the current forestry aims in Europe Part 5. Towards a new forestry development strategy in Poland
Authors: Kaliszewski Adam 
Published: November 2019

Abstract
The aim of this paper was to review and evaluate drafts of forest policy documents that have been developed for the purpose of updating the Polish “National Forest Policy” of 1997, but never entered into force. A total of 14 documents were covered in this analysis including 13 Regional Operational Programmes of the National Forest Policy and the draft of the National Forest Programme (NFP) developed in 2000–2005, as well as nearly 300 recommendations for the “second” NFP, elaborated in 2012–2016.
Very soon after the “National Forest Policy” came into force, it turned out that it needed to be adjusted to changing legal, social and economic conditions. The first attempts to revise and amend the document were made already in 2000. As a result, until 2004, 17 Regional Operational Programmes of the National Forestry Policy were developed and, on that basis, until mid-2005 a draft for a new NFP was worked out. However, the draft was neither adopted nor did it ever enter into force. The second attempt to work out the NFP was made in 2012 and resulted in the development of nearly 300 recommendations to the programme. However, to date, the NFP itself has not been finished.
Most of the documents examined here refer to the current priorities of the European forest policy, and thus they would close gaps in the Polish “National Forest Policy”. In this context, the recommendations to the “second” NFP are of great importance, because they were prepared through a wide participation of various stakeholders and they refer to a wide range of problems, propose specific legal regulations, as well as indicate directions for further development of the Polish forest sector. However, the completion of the NFP is a matter of political decision that rests with the Council of Ministers.
Current possibilities of mechanized logging in mountain areas
Authors: Jodłowski Krzysztof , Kalinowski Michał 
Published: November 2019

AbstractModern technologies allow wood harvest in almost all terrains, including hard-to-reach mountain areas. Each of the technical measures used, however, has limitations due to its construction and the nature of the work. The present study discusses issues related to the selection of machinery and technology as well as planning work in mountainous terrain, taking into account factors such as accessibility of the stand and terrain properties (slope, ground bearing capacity). Adaptive changes of forest machinery for work in mountain stands are also presented. This article furthermore discusses possibilities of applying machinery and technologies already used in other countries to harvest wood in mountainous forests in Poland.
Forests and forestry in the current kindergarten and primary school core curriculum in Poland
Authors: Referowska-Chodak Ewa 
Published: November 2019

Abstract
The aim of this work was to present topics related to forest and forestry in the current core curriculum of pre-school and general primary school education in Poland. For this analysis, teaching content related to forests and forestry was selected from the first three annexes of the Regulation (2017). This content is intended for children starting from the kindergarten age all the way to 8th grade as well as pupils with intellectual disabilities.
In the current core curriculum, there are more topics devoted to forests and forestry than in previous analogous documents. This applies in particular to themes related to forest management, sustainable development and forest functions. Nevertheless, many topics related to biology and forest ecology remained in the curriculum, while little of the teaching content is related to threats and protection of the forest, hunting or harvesting of wood. In recent years, these have been issues that caused a number of social conflicts and controversies. Therefore, the content of forest education, which is not included in the core curriculum, should be thoroughly discussed in particular in non-formal education, because students most often have not previously been exposed to these issues.
The broadened scope of themes related to forests and forestry in the current core curriculum for kindergartens and primary schools is the result of good cooperation between the State Forests and the Ministry of National Education. It would be worthwhile to continue this cooperation to implement coming changes of the above-mentioned document, supplementing the missing content as well as possible.
The Social Evolving: Sociogenomics on the Wings of Social Insects
Authors: Suryanarayanan Sainath 
Published: November 2019

Abstract
This paper excavates the epistemological and ontological foundations of a rapidly emerging field called sociogenomics in relation to the development of social insects as models of social behavior. Its center-stage is “the genome,” where social and environmental information and genetic variation interact to influence social behavior through dynamic shifts in gene expression across multiple bodies and time-scales. With the advent of whole-genome sequencing technology, comparative genomics, and computational tools for mining patterns of association across widely disparate datasets, social insects are being experimented with to identify genetic networks underlying autism, novelty-seeking and aggression evolutionarily shared with humans. Drawing on the writings of key social insect biologists, and historians and philosophers of science, I investigate how the historical development of social insect research on wasps, ants and bees shape central approaches in sociogenomics today, in particular, with regards to shifting understandings of “the individual” in relation to “the social.”
Biopolitics and Becoming in Animal-Technology Assemblages
Authors: Nimmo Richie 
Published: November 2019

Abstract
This article critically explores Foucauldian approaches to the human-animal-technology nexus central to modern industrialised agriculture, in particular those which draw upon Foucault’s conception of power as productive to posit the reconstitution of animal subjectivities in relation to changing agricultural technologies. This is situated in the context of key recent literature addressing animals and biopolitics, and worked through a historical case study of an emergent dairy technology. On this basis it is argued that such approaches contain important insights but also involve risks for the analyses of human-animal-technology relations, especially the risk of subsuming what is irreducible in animal subjectivity and agency under the shaping power of technologies conceived as disciplinary or biopolitical apparatuses. It is argued that this can be avoided by bringing biopolitical analysis into dialogue with currents from actor-network theory in order to trace the formation of biopolitical collectives as heterogeneous assemblages. Drawing upon documentary archive sources, the article explores this by working these different framings of biopolitics through a historical case study of the development of the first mechanical milking machines for use on dairy farms.
Double Jeopardy: How Refugees Fare in One European Labor Market
Authors: Lens Dries , Marx Ive , Vujić Sunčica 
Published: November 2019

Abstract
This paper examines the labor market trajectories of refugees who arrived in Belgium between 1999 and 2009. Belgium offers a relatively easy formal labor market access to refugees and other types of migrants but they face many other barriers in this strongly regulated and institutionalized labor market. Based on a longitudinal dataset that links respondents’ information from the Belgian Labor Force Survey with comprehensive social security data on their work histories, we estimate discrete-time hazard models to analyze refugees’ entry into and exit out of the first employment spell, contrasting their outcomes with family and labor migrants of the same arrival cohort. The analysis shows that refugees take significantly longer to enter their first employment spell as compared with other migrant groups. They also run a greater risk of exiting out of their first employment spell (back) into social assistance and into unemployment. The low employment rates of refugees are thus not only due to a slow integration process upon arrival, but also reflect a disproportional risk of exiting the labor market after a period in work. Our findings indicate that helping refugees into a first job is not sufficient to ensure labor market participation in the long run, because these jobs may be short-lived. Instead, our results provide clear arguments in favor of policies that support sustainable labor market integration.

Published: November 2019

Abstract
Shallow-water models are standard for simulating flow in river systems during floods, including in the near-field of sudden changes in the topography, where vertical flow contraction occurs such as in case of channel overbanking, side spillways or levee overtopping. In the case of stagnant inundation and for frontal flow, the flow configurations are close to the flow over a broad-crested weir with the trapezoidal profile in the flow direction (i.e. inclined upstream and downstream slopes). In this study, results of shallow-water numerical modelling were compared with seven sets of previous experimental observations of flow over a frontal broad-crested weir, to assess the effect of vertical contraction and surface roughness on the accuracy of the computational results. Three different upstream slopes of the broad-crested weir (V:H = 1:Z
1 = 1:1, 1:2, 1:3) and three roughness scenarios were tested. The results indicate that, for smooth surface, numerical simulations overestimate by about 2 to 5% the weir discharge coefficient. In case of a rough surface, the difference between computations and observations reach up to 10%, for high relative roughness. When taking into account mentioned the differences, the shallow-water model may be applied for a range of engineering purposes.
The seepage transport of heavy metal Pb2+ through sand column in the presence of silicon powders
Authors: Bai Bing , Zhai Zhenqian , Rao Dengyu 
Published: November 2019

Abstract
The coupled transport of heavy metals with suspended particles has been a topic of growing interest. The main purpose of this study is to experimentally investigate the seepage transport of heavy metal Pb2+ in the presence of silicon powders (SPs) through a sand column under different seepage velocities (v = 0.087–0.260 cm/s), injection Pb2+ concentrations (C
P = 0–800 μg/ml) and SP sizes (D
50 = 2.8–25.5 μm), which were likely to be encountered in practical engineering. The sand column was installed in a cylindrical chamber of 300 mm in length and 80 mm in internal diameter. The results clearly show that the increase in acidity results in a reduction of the repulsive interactions between SPs and the matrix, and consequently a decrease in the peak values in breakthrough curves (BTCs), especially for larger-sized SPs. The peak values and recovery rate of Pb2+ are obviously increased and an earlier breakthrough can be observed, due to the higher capacity of SPs with negative charge to adsorb heavy metal pollutants such as Pb2+ with positive charge. The adsorption of Pb2+ on SPs can reduce the repulsive forces between SPs and the matrix, thus resulting in the increase of the deposition possibility of SPs and the decrease of peak value and recovery rate.
Predicting impacts of climate change on evapotranspiration and soil moisture for a site with subhumid climate

Published: November 2019

Abstract
The current and ongoing climate change over Europe can be characterized by statistically significant warming trend in all seasons. Warming has also an effect on the hydrological cycle through the precipitation intensity. Consequently, the supposed changes in the distribution and amount of precipitation with the continuously increasing temperature may induce a higher rate in water consumption of the plants, thus the adaptation of the plants to the climate change can be critical. The hydrological impact of climate change was studied based on typical environmental conditions of a specific agricultural area in Austria. For this purpose, (1) a monthly step, Thornthwaite-type water balance model was established and (2) the components of the water balance were projected for the 21st century, both (a) with a basic rooting depth condition (present state) and (b) with a (hypothetically) extended rooting depth (in order to evaluate potential adaption strategies of the plants to the warming). To achieve the main objectives, focus was set on calibrating and validating the model using local reference data. A key parameter of the applied model was the water storage capacity of the soil (SOILMAX), represented in terms of a maximum rooting depth. The latter was assessed and modified considering available data of evapotranspiration and soil physical properties. The adapted model was utilized for projections on the basis of four bias corrected Regional Climate Models. An extended rooting depth as a potential adaptation strategy for effects of climate change was also simulated by increasing SOILMAX. The basic simulation results indicated increasing evapotranspiration and soil moisture annual mean values, but decreasing minimum soil moisture for the 21st century. Seasonal examination, however, revealed that a decrease in soil moisture may occur in the growing season towards to the end of the 21st century. The simulations suggest that the vegetation of the chosen agricultural field may successfully adapt to the water scarcity by growing their roots to the possibly maximum.
The dominant runoff processes on grassland versus bare soil hillslopes in a temperate environment - An experimental study
Authors: Minea Gabriel , Ioana-Toroimac Gabriela , Moroşanu Gabriela 
Published: November 2019

Abstract
This paper aimed to investigate the dominant runoff processes (DRP’s) at plot-scale in the Curvature Subcarpathians under natural rainfall conditions characteristic for Romania’s temperate environment.
The study was based on 32 selected rainfall-runoff events produced during the interval April–September (2014–2017). By comparing water balance on the analyzed Luvisol plots for two types of land use (grassland vs. bare soil), we showed that DRP’s are mostly formed by Hortonian Overland Flow (HOF), 47% vs. 59% respectively. On grassland, HOF is followed by Deep Percolation (DP, 31%) and Fast Subsurface Flow (SSF, 22%), whereas, on bare soil, DP shows a higher percentage (38%) and SSF a lower one (3%), which suggests that the soil-root interface controls the runoff generation.
Concerning the relationship between antecedent precipitation and runoff, the study indicated the nonlinearity of the two processes, more obvious on grassland and in drought conditions than on bare soil and in wet conditions (as demonstrated by the higher runoff coefficients). Moreover, the HOF appeared to respond differently to rainfall events on the two plots - slightly longer lag-time, lower discharge and lower volume on grassland - which suggests the hydrologic key role of vegetation in runoff generation processes.
Long term variations of river temperature and the influence of air temperature and river discharge: case study of Kupa River watershed in Croatia

Published: November 2019

Abstract
The bio-chemical and physical characteristics of a river are directly affected by water temperature, which therefore affects the overall health of aquatic ecosystems. In this study, long term variations of river water temperatures (RWT) in Kupa River watershed, Croatia were investigated. It is shown that the RWT in the studied river stations increased about 0.0232–0.0796ºC per year, which are comparable with long term observations reported for rivers in other regions, indicating an apparent warming trend. RWT rises during the past 20 years have not been constant for different periods of the year, and the contrasts between stations regarding RWT increases vary seasonally. Additionally, multilayer perceptron neural network models (MLPNN) and adaptive neuro-fuzzy inference systems (ANFIS) models were implemented to simulate daily RWT, using air temperature (Ta
), flow discharge (Q) and the day of year (DOY) as predictors. Results showed that compared to the individual variable alone with Ta
as input, combining Ta
and Q in the MLPNN and ANFIS models explained temporal variations of daily RWT more accurately. The best accuracy was achieved when the three inputs (Ta
, Q and the DOY) were included as predictors. Modeling results indicate that the developed models can well reproduce the seasonal dynamics of RWT in each river, and the models may be used for future projections of RWT by coupling with regional climate models.
Adaptive stochastic management of the storage function for a large open reservoir using an artificial intelligence method
Authors: Kozel Tomas , Stary Milos 
Published: November 2019

Abstract
The design and evaluation of algorithms for adaptive stochastic control of reservoir function of the water reservoir using artificial intelligence methods (learning fuzzy model and neural networks) are described in this article. This procedure was tested on an artificial reservoir. Reservoir parameters have been designed to cause critical disturbances during the control process, and therefore the influences of control algorithms can be demonstrated in the course of controlled outflow of water from the reservoir. The results of the stochastic adaptive models were compared. Further, stochastic model results were compared with a resultant course of management obtained using the method of classical optimisation (differential evolution), which used stochastic forecast data from real series (100% forecast). Finally, the results of the dispatcher graph and adaptive stochastic control were compared. Achieved results of adaptive stochastic management provide inspiration for continuing research in the field.
