Populations are increasingly fragmented, and only a coordinated conservation effort at the European level may guarantee its long-term survival. To obtain a general population genetic picture on a larger geographic scale, we screened 117 individuals from seven local populations in Hungary, Romania, and Austria for allelic variation at eleven microsatellite loci. We found a high (23.4%) proportion of private alleles, and a moderate to somewhat elevated level (15.27%) of partitioning of genetic diversity among populations, compared to that found in many other terrestrial mammals. Genetic variability was significantly higher than in earlier studied Czech populations that are considered genetically depleted, but significantly lower than in undisturbed populations of S. suslicus and S. brunneus, that are similar to the European ground squirrel in their ecological requirements, reproductive biology, and social organization. Genetic diversity was also lower than in most presumably "undisturbed" populations of other Sciurid species. This, together with the observed level and pattern of genetic differentiation among populations, such as no significant increase of genetic differentiation with geographic distance and similar variance of genetic differentiation between populations independent of geographic distance, indicated the prevalence of relatively strong drift effects for all populations. A Bayesian STRUCTURE analysis and a factorial correspondence analysis concordantly revealed a fairly complex genetic composition of local populations, but no major geographic trend in the pattern of the genetic composition. Overall, the results suggest disintegration of local colonies that might earlier have been more connected genetically. The STRUCTURE analysis also suggested anthropogenic translocations among single Hungarian populations. Our data on genetic diversity and its distribution do not object to such conservation measures. Translocation of individuals particularly from nearby populations may increase the chances of survival of small and isolated populations and counteract inbreeding at low densities.

However, ecosystem scale investigations on their abundance and dynamics are scarce because their high spatio-temporal heterogeneity requires huge sample size. Processing and identifying large number of individuals are extremely labour-intensive. We prototyped a device called EDAPHOLOG monitoring system that consists of (1) a probe that catches and detects microarthropods and estimates their body size; (2) a data logger transmitting data to a central data base; and (3) a Java application for retrieving data. We tested the device in three ways. First, we tested the precision and accuracy of detection and body size estimation of the device in the laboratory using microarthropods of five morphotypes: euedaphic Collembola, haired Collembola, scaled Collembola, Acari and Oribatida. Secondly, we compared the number of individuals collected by EDAPHOLOG traps, pitfall traps and soil extraction method in an alfalfa field. Thirdly, we deployed a total of 100 EDAPHOLOG probes in nine different habitats for over 3 months to demonstrate the applicability of the monitoring system. In the laboratory, EDAPHOLOG detected 95·6% of individuals; even the smallest morphotype (Oribatida, body size (mean ± SE): 0·58 ± 0·04 mm) was detected in 87·5% of cases. For body length estimation, we established a quadratic relationship between the estimated and measured body lengths; however, the R2 of the quadratic model was only 0·32. By comparing the three different sampling methods (EDAPHOLOG, pitfall traps and soil extraction), we concluded that EDAPHOLOG traps better select for soil microarthropods compared to classical pitfall traps, since the latter ones caught also many other arthropod species. Furthermore, the EDAPHOLOG traps caught more epigeic microarthropods and almost the same number of soil-dwelling euedaphic microarthropods as the numbers collected by soil extraction. During the 3-month-long field test, the total numbers of detected and captured individuals agreed very well, although the device tended to overestimate the number probably due to counting also some soil particles falling into the probe. This trend was the same regardless of the total number caught. Surface-dwelling epigeic and litter-dwelling hemiedaphic microarthropods dominated the samples although soil-dwelling euedaphic microarthropods were also caught. EDAPHOLOG is a novel device that consumes little power, rugged enough to operate in the field for extended periods of time, and can be remotely controlled. It detects surface- and soil-dwelling microarthropods real-time, and with high accuracy; however, it is less accurate to estimate body size. The system is especially suitable in field research focusing on temporal activity of microarthropods. Because it is non-invasive, studies requiring long-term monitoring, such as soil remediation or ecosystem restoration projects, will also find EDAPHOLOG useful. © 2016 British Ecological Society.}, keywords = {sensors; Acari; COLLEMBOLA; Pitfall traps; Trapping probes; Soil mesofauna; Real-time monitoring; Arthropod trapping}, year = {2017}, eissn = {2041-2096}, pages = {313-321}, orcid-numbers = {Kosztolányi, András/0000-0002-9109-5871; Gedeon, Csongor István/0000-0003-4027-2409} } @CONFERENCE{MTMT:2180270, title = {Results of a country-scale on the effects of agricultural practices on soil mesofauna in Hungary}, url = {https://m2.mtmt.hu/api/publication/2180270}, author = {Dombos, Miklós and Gedeon, Csongor István and László, Péter and Szabó, József}, booktitle = {EUROSOIL 2012 - 4th International Congress of the European Confederation of Soil Science Societies}, unique-id = {2180270}, year = {2012}, pages = {869}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:3059079, title = {EXAMINATIONS OF WEED FLORA AT DIFFERENT NITROGEN LEVELS IN A LONG-TERM FIELD EXPERIMENT}, url = {https://m2.mtmt.hu/api/publication/3059079}, author = {Dóra, Vikár and Mazsu, Nikolett and Gedeon, Csongor István and Szalai, Magdolna Zita and Lehoczky, Éva}, journal-iso = {NÖVÉNYTERMELÉS}, journal = {NÖVÉNYTERMELÉS}, volume = {65}, unique-id = {3059079}, issn = {0546-8191}, year = {2016}, pages = {87-90}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409; Lehoczky, Éva/0000-0002-6538-4055} } @article{MTMT:3092979, title = {The effect of mulching on the abundance and diversity of ground beetle assemblages in two hungarian potato fields}, url = {https://m2.mtmt.hu/api/publication/3092979}, author = {Dudás, Péter and Gedeon, Csongor István and Menyhárt, László and Ambrus, Gergely and Tóth, Ferenc}, doi = {10.18380/SZIE.COLUM.2016.3.1.45}, journal-iso = {COLUMELLA}, journal = {COLUMELLA: JOURNAL OF AGRICULTURAL AND ENVIRONMENTAL SCIENCES}, volume = {3}, unique-id = {3092979}, issn = {2064-7816}, year = {2016}, eissn = {2064-9479}, pages = {45-53}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409; Tóth, Ferenc/0000-0003-4515-556X} } @article{MTMT:30676022, title = {Overlooked links between soils, provisioning ecosystem services, and human health}, url = {https://m2.mtmt.hu/api/publication/30676022}, author = {Eric, C.

However, despite a rich literature exploring links between ES and human health, few studies have investigated links between soil ES and human health. Viewing the relationship between soils and human health through the ES lens reveals that soil ES such as the provisioning of shelter, clothing, and fuel have been overlooked in the soil and human health literature. Shelter provides protection against inclement weather, temperature extremes, and other potential threats, and therefore supports human health. Clothing provides a more consistent micro-environment around the skin, provides protection from ultraviolet radiation, and also provides protection from some parasites (although it can enhance the presence of other parasites). Fuel is required to warm shelters, which provides refuge from cold temperatures. Fuel also allows us to cook food, which reduces disease.Soils supply materials (wood, straw, cotton, wool, etc.) in support of these functions in ways that are often more environmentally responsible than is the case with many modern building and clothing materials or with fossil fuels. However, it is important to realize that sustainable management practices are critical in order to achieve environmentally responsible production of these products.

They are important in such ecosystem functions as the improvement of soil quality or they are important prey for raptors. Besides people often visit their colonies for outdoor recreation or education. If they vanish the soils’ macrofauna diversity decreases, which is an overall indicator of soil health. Consequently, they are keystone, flagship species of grasslands and their monitoring is recommended. However, colonies go extinct due to land use changes or unknown reasons. Our primary aim is to develop an automated, non-invasive method to detect, count and map animal burrows and estimate population size more accurately. Problem: According to their monitoring actively used burrow entrances are counted per hectare. Then this number is extended to the area occupied by the colony. Two main systematic errors make the population estimation inaccurate and relative. First, it considers the animals’ distribution even on the entire area, second, the estimated ratio of burrow entrances per each individual is inaccurate. Innovation: The method includes detection and counting of burrow entrances and mounds, and then, determining the number of burrow systems per area. Each animal occupies one burrow system. To fulfil our plan we use proximal surface sensing, such as UAV (camera and DGPS): for automatic burrow entrance or mound recognition and counting. We also apply proximal subsurface sensing, such as GPR (DGPS) up to a depth of 1.0 m: for burrow mapping. Finally, the surface and subsurface models of the burrow systems are interconnected visually. Impact: Accurate population estimation would give nature conservationists an early warning system so that they can intervene when colonies begin to decline in time.}, year = {2018}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409; Mészáros, János/0000-0003-2604-3052} } @misc{MTMT:30642024, title = {Population size, ecological isolation, and genetic diversity in European ground squirrels. előadás}, url = {https://m2.mtmt.hu/api/publication/30642024}, author = {Gedeon, Csongor István and Hoffmann, Ilse and Váczi, Olivér and Knauer, Felix and Suchentrunk, Franz}, unique-id = {30642024}, year = {2018}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:3296176, title = {THE ROLE OF LANDSCAPE HISTORY IN DETERMINING ALLELIC RICHNESS OF EUROPEAN GROUND SQUIRRELS (SPERMOPHILUS CITELLUS) IN CENTRAL EUROPE}, url = {https://m2.mtmt.hu/api/publication/3296176}, author = {Gedeon, Csongor István and Hoffmann, I and Váczi, O and Knauer, F and Hichem, S and Stefanovic, M and Lehoczky, Éva and Laborczi, Annamária and Suchentrunk, F}, doi = {10.4404/hystrix-28.2-11823}, journal-iso = {HYSTRIX}, journal = {HYSTRIX-ITALIAN JOURNAL OF MAMMALOGY}, volume = {28}, unique-id = {3296176}, issn = {0394-1914}, abstract = {Genetic diversity is of paramount importance for individual fitness and evolutionary potential of populations. For conservation planning it is crucial to know how genetically diverse a species is and what factors may explain variation of genetic diversity among populations. Our aim was to evaluate the effects of landscape history, ecological isolation, and local population size on allelic richness of local populations in European ground squirrels (Spermophiluscitellus). We genotyped 144 individuals from nine local populations collected in two neighbouring regions with decades of different landscape history. We assessed allelic richness, ecological isolation and local population size by eleven polymorphic microsatellites, the isolation index of Rodríguez and Delibes,and standardised counts of burrows openings, respectively. Statistical models indicated a strong effect of landscape history on allelic richness of local populations. Ecological isolation of local populations apparently played only a marginal role, and local population size was an unimportant factor. Our modelling results highlight the dominant role of landscape history for the genetic diversity of S. citellus. The strong landscape history effect encountered presently includes a different region-specific socio-economic development due to distinct agricultural systems in the two regions, especially after World War II. Levels of ecological isolation of local populations have diverged in an extent too small to explain variation of local allelic richness. The lack of significant effect of local population size suggests that census sizes of the populations studied are all not critically low. Moreover,census and estimated effective population sizes were not closely related.

To facilitate genetic monitoring of the endangered European ground squirrel (EGS), we analyzed 382 individuals from 16 populations in Central Europe, covering almost half of its natural range. We tested how fragmentation affects the genetic architecture of presumably selectively neutral (12 microsatellites) and non-neutral (the major histocompatibility class II DRB gene) loci. Spatial genetic analyses defined two groups of populations, "western" and "eastern", with a significantly higher level of habitat fragmentation in the former group. The highly fragmented western populations had significantly lower genetic diversity in both types of markers. Only one allele of the DRB gene predominated in populations of the western group, while four alleles were evenly distributed across the eastern populations. Coefficient of inbreeding values (FIS) calculated from microsatellites were significantly higher in the western (0. 27-0. 79) than in eastern populations (-0. 060-0. 119). Inter-population differentiation was very high, but similar in both groups (western FST = 0. 23, eastern FST = 0. 25). The test of isolation by distance was significant for the whole dataset, as well as for the two groups analyzed separately. Comparison of genetic variability and structure on microsatellites and the DRB gene does not provide any evidence for contemporary selection on MHC genes. We suggest that genetic drift in small bottlenecked and fragmented populations may overact the role of balancing selection. Based on the resulting risk of inbreeding depression in the western populations, we support population management by crossbreeding between the western and eastern populations. © 2011 Springer Science+Business Media B.V.}, keywords = {ALLELE; genetic marker; Central Europe; Genetic Variation; natural selection; major histocompatibility complex; genetic structure; Spermophilus citellus; habitat fragmentation; rodent; INBREEDING DEPRESSION; Genetic Drift; Endangered species; population bottleneck; species conservation; conservation genetics; Sciuridae; MHC class II; captive breeding; interpopulation variation; Souslik; DRB}, year = {2011}, eissn = {1572-9737}, pages = {1115-1129}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:33704038, title = {Predicting microbial responses to changes in soil physical and chemical properties under different land management}, url = {https://m2.mtmt.hu/api/publication/33704038}, author = {Sadeghi, Sara and Petermann, Billi Jean and Steffan, Joshua J. and Brevik, Eric C. and Gedeon, Csongor István}, doi = {10.1016/j.apsoil.2023.104878}, journal-iso = {APPL SOIL ECOL}, journal = {APPLIED SOIL ECOLOGY}, volume = {188}, unique-id = {33704038}, issn = {0929-1393}, year = {2023}, eissn = {1873-0272}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @CONFERENCE{MTMT:30423274, title = {No signal of molecular adaptation in the NADH6 dehydrogenase gene in brown hares (Lepus europaeus) from Europe and Asia Minor}, url = {https://m2.mtmt.hu/api/publication/30423274}, author = {Stefanovic, M and Djan, M and Velickovic, N and Knauer, F and Demirbas, Y and Posautz, A and Kübber-Heiss, A and Beiglböck, C and Paule, L and Gedeon, Csongor István and Suchentrunk, F.}, booktitle = {6th International Wildlife and Game Management Symposium: Modern Aspects of Sustainable Management of Game Populations : Book of Abstracts}, unique-id = {30423274}, year = {2018}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:31269400, title = {Purifying selection shaping the evolution of the Toll-like receptor 2 TIR domain in brown hares (Lepus europaeus) from Europe and the Middle East}, url = {https://m2.mtmt.hu/api/publication/31269400}, author = {Stefanović, Milomir and Djan, Mihajla and Veličković, Nevena and Demirbaş, Yasin and Paule, Ladislav and Gedeon, Csongor István and Posautz, Annika and Beiglböck, Christoph and Kübber-Heiss, Anna and Suchentrunk, Franz}, doi = {10.1007/s11033-020-05382-x}, journal-iso = {MOL BIOL REP}, journal = {MOLECULAR BIOLOGY REPORTS}, volume = {47}, unique-id = {31269400}, issn = {0301-4851}, year = {2020}, eissn = {1573-4978}, pages = {2975-2984}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:30887004, title = {Positive selection and precipitation effects on the mitochondrial NADH dehydrogenase subunit 6 gene in brown hares (Lepus europaeus) under a phylogeographic perspective}, url = {https://m2.mtmt.hu/api/publication/30887004}, author = {Stefanović, Milomir and Djan, Mihajla and Veličković, Nevena and Beuković, Dejan and Lavadinović, Vukan and Zhelev, Chavdar Dinev and Demirbaş, Yasin and Paule, Ladislav and Gedeon, Csongor István and Mamuris, Zissis and Posautz, Annika and Beiglböck, Christoph and Kübber-Heiss, Anna and Suchentrunk, Franz}, doi = {10.1371/journal.pone.0224902}, journal-iso = {PLOS ONE}, journal = {PLOS ONE}, volume = {14}, unique-id = {30887004}, issn = {1932-6203}, year = {2019}, eissn = {1932-6203}, orcid-numbers = {Gedeon, Csongor István/0000-0003-4027-2409} } @article{MTMT:1442686, title = {Morphology and function of communal mounds of overwintering Mound-building mice (Mus spicilegus)}, url = {https://m2.mtmt.hu/api/publication/1442686}, author = {Szenczi, Péter and Bánszegi, Oxána and Dúcs, A and Markó, Gábor and Gedeon, Csongor István and Németh, I and Altbäcker, Vilmos}, doi = {10.1644/10-MAMM-A-258.1}, journal-iso = {J MAMMAL}, journal = {JOURNAL OF MAMMALOGY}, volume = {92}, unique-id = {1442686}, issn = {0022-2372}, abstract = {Mound-building mice (Mus spicilegus) construct large mounds of soil and plant material in autumn, where juvenile animals overwinter in groups without reproducing. The mounds may have several functions, including food storage, thermoregulation, and protection from predators. We examined whether these mounds have food storage or thermoregulatory function. Mice mainly utilized seeds and ears of certain plants (Echinochloa sp., Chenopodium spp., and Setaria spp., depending on availability) as building materials but microhistological analysis of mice feces revealed that the cached plants are not represented in their actual diet. By comparing the features of soil under the mound to neighboring random points we found that the mounds have water insulating and thermoregulatory properties. We also found a positive correlation between the size of the mound, its vegetal content, and its effectiveness to lessen the impact of the harsh conditions of the outside environment. Mound size was dependent on the number of inhabitants, indicating that larger mounds are constructed by and shelter bigger groups. The existence of communal mound building thus may greatly contribute to successful overwintering and the relatively low population size fluctuation in this species.}, keywords = {THERMOREGULATION; reproduction; DIET; MATING SYSTEM; SPERMOPHILUS-CITELLUS; Mus spicilegus; MAMMALS; MUSCULUS-DOMESTICUS; DAILY TORPOR; PENDULINE TITS; VOLES MICROTUS-AGRESTIS; NESTS; EUROPEAN GROUND-SQUIRRELS; water insulation; overwinter}, year = {2011}, eissn = {1545-1542}, pages = {852-860}, orcid-numbers = {Markó, Gábor/0000-0003-1351-4070; Gedeon, Csongor István/0000-0003-4027-2409; Altbäcker, Vilmos/0000-0001-7592-1232} } @CONFERENCE{MTMT:30322921, title = {Persistent decline of the European Ground Squirrel (Spermophilus citellus), an iconic steppe rodent in the heart of its distribution}, url = {https://m2.mtmt.hu/api/publication/30322921}, author = {Cserkész, Tamás and L., Nagy and Csathó, András István and Németh, Attila and T., Szitta and Váczi, Olivér and Gedeon, Csongor István and Cs., Kiss}, booktitle = {VII.
