Our study focused on explosion craters – a small-scale disturbance type of high severity, and their effect on species diversity including vascular plants, bryophytes and lichens. The research was carried out on an active military training area in Nowa Dęba (SE Poland). The examined vegetation represented open communities on nutrient-poor soils with a wide range of soil moisture conditions. We compared 76 pairs of vegetation samples, each pair consisting of a crater and a closely located control plot of the same size. Out of 135 species recorded (72 vascular plants, 33 mosses, 9 liverworts, 22 lichens), 37 were found only in craters, while 19 occurred only in control plots. Both, species number and diversity were significantly higher for craters than controls. In general, the positive effect of cratering on all studied groups rises from dry to wet habitats. The highest increase of diversity was observed in relation to bryophytes in the moist habitats. Moreover, craters within habitats of higher moisture turned out to be more resistant to alien colonization and at the same time were characterized by significantly higher number of red-listed species compared to the control plots. Differences in species composition between craters and undisturbed plots were most visible in moderately moist habitats. We found several species with a strong preference for craters, and the plants of the highest indicative value are Atrichum tenellum and Dicranella cerviculata.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"67 1","pages":"194 - 205"},"PeriodicalIF":0.5,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45945507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative vegetative and generative characteristics of the plants were determined. Measurements were carried out at three distances from the edge of the road and on control plots. The results showed that the growth and reproduction of E. crus-galli and D. sanguinalis occur in the period when the values of soil environmental variables correspond to values of non-saline soil according to the criteria for soil salinity assessment. Despite this fact, the average salinity of soil along roadside was still higher than in soil of further distances and we found these levels of salinity to be well tolerated by the study species. Therefore, we conclude that roadsides with the same or higher salt content represent a suitable location for the occurrence and reproduction of E. crus-galli and D. sanguinalis, thus being temporary locations that enable their further spreading to the countryside.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"67 1","pages":"186 - 193"},"PeriodicalIF":0.5,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46223632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four pitfall trapping events per month were conducted from March until November to test for temporal, spatial and habitat-related segregation of species. Primary results show a high level of temporal segregation of species within and between the guilds (Aphodiidae – dwellers, Geotrupidae – tunnelers, Scarabaeidae – tunnelers, Scarabaeidae – rollers). Temporal segregation of monthly samples was evident between Aphodiidae – dwellers (most active at the beginning and end of the season, with a month of complete inactivity during hot summer) and Scarabaeidae – tunnelers (present all the time, but with least species and specimens at the beginning and end of season). Intra-guild competition was most prominent for Aphodiidae – dwellers and Geotrupidae – tunnelers, where species show high rate of temporal avoidance to minimize interspecies competition for the same food source. Finally, geographical (site-related) and habitat-related (S1, S2, S3) differences were found in species composition, species richness and abundance, however for the latter two parameters only at habitat level (more species at S1, but higher abundances at S2 and S3). The results imply that the pronounced temporal and spatial segregation facilitate higher biodiversity in space and time, and allow more species to co-exist at the same sites over time.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"67 1","pages":"247 - 263"},"PeriodicalIF":0.5,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46757374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the mean density of litter spiders was significantly greater in wind-shielded area than wind-exposed area. There was a marked impact of structure and depth of litter layers on guild composition, but not on the diversity indices of the litter spider communities. The litter invertebrates and decomposition rates did not differ between enclosures with/without spiders. However, there was a marked difference in litter arthropod abundance between monsoon and non-monsoon seasons in wind-exposed areas. The decomposition rate was remarkably greater in non-monsoon seasons than in monsoon seasons, whereas there were no marked differences between wind-shielded and wind-exposed locations. It was concluded that litter arthropod distribution and related decomposition were affected by variation of monsoon seasons but not by spider presence/absence in Nanjenshan Rain Forest.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"67 1","pages":"231 - 246"},"PeriodicalIF":0.5,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48125886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the environment probably does not provide enough shelters for all birds from a winter flock to roost, a competition for best sites, as nest boxes, probably occurs. Therefore, the aim of this study was to describe the pattern of using the nest boxes by birds for roosting during three consecutive winter seasons and to determine the structure of a group of roosting birds in relation to the winter flock. Tits were captured and marked; daily controls of nest boxes were performed to find out which of them the tits used for roosting and subsequently, birds entering these boxes were caught at night. Great tits Parus major were the most abundant species roosting in the studied boxes with proportion of blue tits Cyanistes caeruleus differed between years. Young individuals prevailed among the birds roosting in nest boxes. However the age and sex structure of great tits roosting in nest boxes was similar to that observed in winter flocks, which was in contrast to earlier studies that found that the males and older individuals, high in the social hierarchy of the flock, will take over these boxes. The size of winter flock differs strongly among winters, thus it is possible that the level of competition for these roosting sites also varies between the years.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"67 1","pages":"148 - 158"},"PeriodicalIF":0.5,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70022716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate and compare the influence of volatile and aqueous extracts from C. epigejos on initial recruitment of typical mesic meadow species (Daucus carota, Rumex acetosa, Festuca pratensis and Dactylis glomerata). The activity of allelochemicals contained within above-ground biomass, below-ground biomass and necromass of the donor plant was estimated. Using gas chromatography-mass spectrometry technique led to the identification of 19 compounds (alcohols, aldehydes, ketones and esters) in C. epigejos volatile extracts. Aliphatic alcohols were the main group of identified chemicals, including (Z)-3-hexen-1-ol acetate. The laboratory tests showed a significant inhibitory influence of volatile C. epigejos extracts on the growth of D. glomerata, D. carota and R. acetosa roots. The influence of aqueous C. epigejos extracts on selected meadow species was less evident. Only the seeds of D. glomerata and F. pratensis were found to be susceptible to water extracts of above-ground C. epigejos biomass. The seed germination was stimulated by the extracts at low concentrations but inhibited at higher concentrations. Among the tested plants only the growth of F. pratensis seedlings was inhibited by aqueous extracts obtained from all examined C. epigejos parts. In regarding to the other test species the effect of C. epigejos extracts was neutral or positive.
