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.

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. Future studies are needed that investigate the links between these overlooked soil ES and human health.

Four colonies were studied June September 2004 to examine function of mounds with respect to vigilance for predators, and to estimate magnitude of soil mixed by these prairie dogs. Frequency of vigilance atop mounds increased in taller vegetation and individuals at perimeters of colonies oriented toward the outside more frequently than to the interior of colonies. Mounds accounted for an average of 10,374 kg of soil/ha that was excavated from the burrow. This mass of subsoil moved to the surface and the 7-17 m(3) of air in the burrow make the geomorphic effect of prairie dogs potentially significant.

Poster TS - Poster PY - 2018 UR - https://m2.mtmt.hu/api/publication/30642039 ID - 30642039 AB - Background: Burrowing by protected, subterranean European ground squirrels or Lesser blind mole-rats increase landscape heterogeneity and improve the availability of resources to other organisms of semi-arid grasslands of Central Europe. 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.

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. Establishing corridors or translocating S. citellus in the species’ historical range should be encouraged to promote gene flow between local populations and counteract the loss of genetic diversity by drift, provided that no conflicting factors (ecological, epidemiological, etc.) exist.

Nevertheless, wildlife management lacks both a carefully developed and tested translocation guide and methods. We evaluated conditions of release method (time of release and retention of animals) that affect short-term settlement of translocated ground squirrels in the central region of Hungary. In a field experiment, we translocated 117 individuals from an international airport to a protected site in 2000. We found that release time should precede the animals' natural, daily activity peak. The use of retention caps combined with artificial burrows instead of complex acclimation cages works successfully to prevent animals from dispersing from the release site.

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.

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.
