The understanding of the effect of noise on different animal populations is mandatory to help making informed decisions in the field of natural resource management. While managers often focus on rare, charismatic species, it is important to examine the effects of noise on species that are common because abundant species have strong ecological impacts. This paper describes the influence of traffic noise on representatives of two orders of mammals: rodents and bats. I reviewed field and laboratory studies that inspected the influence of traffic noise on the following aspects of rodent and bat ecology: (1) activity and behaviour, (2) abundance and habitat use, and (3) foraging. Bats tended to be negatively affected by traffic noise, although certain species demonstrated a considerable degree of tolerance to this disturbance. The effects of traffic noise on rodents were more varied, but typically consisted of detrimental changes in vigilance-foraging trade-off. However, research on rodents appears biased towards social species which rely on alarm calls for protection.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"68 1","pages":"323 - 333"},"PeriodicalIF":0.5,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44423729","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 study aimed to evaluate the effect of the habitat structure of the FWB buffer zone on macrophyte association diversity in the FWBs (n = 49). As many as 175 species of vascular plants, three stoneworts, and 40 (41–49 according to Chao2 estimator) plant associations were recognized, including 19 of high conservation priority. The occurrence of threatened associations (0–5 per FWB) was not correlated with the number of common (unthreatened) ones. The most important predictors of plant diversity (at the species level and the association level) were the connection of the FWB with a watercourse (positive effect), and the distance from the FWB to the nearest built-up areas (positive effect). The results suggest that even though the high percentage cover of perennial vegetation mitigates the effect of diffused pollutions of agricultural origin on FWB biota, its significance may become low when the distance from a built-up area to FWBs is small.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"68 1","pages":"263 - 282"},"PeriodicalIF":0.5,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48733132","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}

Overwintering in the studied population of Vertigo moulinsiana is effective enough to allow the majority of it to survive. The population dynamics of V. moulinsiana is specific, where the summer boom in a suboptimal habitat covering a small area (wet patches of sweet grass) can determine the snail's range over much larger areas. Our results suggest that humidity could have been the major factor governing population increase. The summer boom is caused by juveniles appearing in very large numbers during this period, thus the peak height is mostly influenced by the considerable susceptibility of juveniles and eggs to desiccation. The limiting influence of humidity is evident in the unequal spatial distribution of individuals: the wetter the substrate, the greater the abundance of snails. As a consequence, the boom may be spatially regulated and only occurs in wet habitats, even though the snail actually occupies a much larger area. Our results indicate that this V. moulinsiana population does not follow typical models constructed for vertebrates or other animals with high dispersal abilities, like the Ideal Free Distribution (IFD) model, and requires a specific approach. Its specific spatiotemporal pattern should be taken into account during monitoring surveys and conservation actions.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"68 1","pages":"229 - 241"},"PeriodicalIF":0.5,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42799230","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 present study assessed the relationship between species richness and vegetation cover, as well as underlying biological mechanisms in three Mongolian grasslands, namely meadow, dry steppe and mountain steppe. Each of three grasslands was set by two treatments: grazing exclusion by fence and freely grazing. I measured plant species richness, vegetation cover, height and phenology. I examined three biological mechanisms, namely plant interactions, the role of dominant species and vegetation growth periods. The results showed that higher species richness generally increased vegetation cover independent of fencing treatment and grassland type. Plant interactions were the strongest in fenced plots of the mountain steppe. Dominant plant species invested more in vegetation cover rather than the height in grazed plots than fenced ones in Mongolian grasslands. Taking vegetation growth periods into account did not alter the strength and the direction of the relationship between species richness and vegetation cover. I thus infer that examining changes in species diversity will allow for a better understanding of vegetation cover dynamics in grasslands. This will help to assess how ecosystem functioning might be impacted by grazing disturbances in Mongolia.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"68 1","pages":"211 - 228"},"PeriodicalIF":0.5,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43276822","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 forests are regarded as ones of the most diverse and distinct terrestrial habitats on earth. They also play a crucial role in wildlife conservation as corridors and refugia for wildlife. It is hypothesized that the closer to the river bank, the higher the species diversity, while population densities may increase with the increase of the distance from the river bank. In 2014, quantitative studies (by means of the mapping method) on avian community breeding in such forest on Zambezi River in Katima Mulilo were undertaken to measure this gradient. Four plots were designed along an increasing distance from the river bank in this forest. In terms of the number of species, there was a significant gradual decrease with the increasing distance from the bank (from 91 to 54 species). The number of breeding pairs per 100 ha increased with the moisture gradient (from 222 to 677). Shannon's (H') and Simpson's (D) indices were higher in the two plots closer to the bank river (H'= 3.44–3.85; D = 0.97–0.99), than in the two remaining plots (H' = 3.13–3.15; D = 0.92–0.93). Also the Pielou's Evenness Index was higher in two plots closer to the bank (J' = 0.84–0.85 vs. 0.77–0.78). The proportion of granivores in the avian community declined along the moisture gradient, while that of insectivores and frugivores – increased. These gradual changes can be linked to a parallel gradual changes of the amount of fruits and invertebrates.","PeriodicalId":49683,"journal":{"name":"Polish Journal of Ecology","volume":"68 1","pages":"251 - 262"},"PeriodicalIF":0.5,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46874426","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}

Although both managed and partially protected stands differed in the intensity of management and the type of selection cuttings, we found little difference in the composition and stand structure. Regardless of management intensity all stands were characterized by diversified natural regeneration, where the main tree species, especially in the phase of seedlings, was silver fir. The basal area of standing dead trees was higher for the protected than managed stands, but the differences were not significant, whereas the mean volume of dead standing trees was significantly higher in the reserve.

The natural difference in the isotopic composition of carbon (C) between the spruce and maize allowed us to estimate the proportions of different carbon sources in the tissues of soil animals. The dependence on litter-derived C was least pronounced in Collembola having low δ15N values, indicating the feeding on non-vascular plants. In contrast, collembolans having high δ15N values belonged to the food chains based on fresh plant residuals. These results suggest that different species of litter-dwelling collembolans may regulate substantially different energy channels.
