Abstract In different types of substrate (soil, litter, lichens and mosses) collected at three memorial complexes (cemeteries) of Kyiv (Ukraine), 70 species from 57 genera, 34 families of oribatid mites were found. A few eurytopic species capable of tolerance to different types of pollution make up an essential part in each species complex. The species diversity and complexity of oribatid community structure at researched areas increased with distance from the city center. There was no direct relation between the degree of dominance of most common species and the cemetery’s relative remoteness from the center of the city.

With the increasing number of people starting to attach importance to urban green space (UGS), estimating urban residents’ demand for UGS has become critical. Previous studies have estimated residents’ demands for UGS in different cities using the Rosen–Roback model. However, there has been little analysis of the renters’ requirements for UGS or the dynamic and heterogeneous demands for UGS by residents in cities with varying characteristics. In this study, the prefecture-level cities in China were selected as the object of study for their wide representation of various city characteristics, and the Rosen–Roback model was used to address the abovementioned issues. Residents’ demand for UGS in 285 prefecture-level cities was assessed from 2010 to 2017. The results confirm our hypothesis that when UGS increases by 1%, house prices will increase by about 3% and rents will increase by about 7%, and the demand continues to grow. We also analyzed the heterogeneous demands for UGS by urban residents in different types of cities from three aspects: population density, economic level, and the effects of the National Forest City policy. Finally, we provided suggestions based on empirical results for planning and managing UGS.

Species diversity, dominance and abundance of the phytoplankton community of the Ranjit Sager Wetland were studied during June, 2012 to May, 2014 on monthly basis. The main aim was to provide information about overall phytoplankton diversity of this wetland. Phytoplankton samples were collected using phytoplankton net and preserved in 5% formaldehyde solution on the spot, then brought to the laboratory for further analysis. Algae belonging to Cyanophyceae, Chlorophyceae and Bacillariophyceae were recorded. The Bacillariophyceae was the most dominant group followed by the Chlorophyceae and Cyanophyceae. A total of 26 genera were recorded, 12 were belonged to Bacillariophyceae, 11 to Chlorophyceae and 3 to Cyanophyceae. The different types of indices such as Margalef’s index, Simpson index, Shannon-Weaver index and species evenness index were employed to analysis the data. Phytoplankton converts light energy to chemical energy by the process of photosynthesis so they act as primary producers and food for variety of aquatic organisms. Phytoplankton are also act as efficient bio-indicators to measure quality of water.

Drought periods have an adverse impact on the condition of oak stands. Research on different types of ecosystems has confirmed a correlation between plant species diversity and the adverse effects of droughts. The purpose of this study was to investigate the changes which occurred in an oak stand (Krotoszyn Plateau, Poland) under the impact of the summer drought in 2015. We used a method based on remote sensing indices from satellite images in order to detect changes in the vegetation in 2014 and 2015. A positive difference was interpreted as an improvement, whereas a negative one was treated as a deterioration of the stand condition. The Shannon-Wiener species diversity was estimated using an iterative PCA algorithm based on aerial images. We observed a relationship between the species indices of the individual forest divisions and their response to drought. The highest correlation between the index differences and the Shannon-Wiener indices was found for the GNDVI index (+0.74). In addition, correlations were observed between the mean index difference and the percentage shares in the forest divisions of species such as Pinus sylvestris (+0.67 ± 0.08) and Quercus robur (-0.65 ± 0.10). Our results lead us to infer that forest management based on highly diverse habitats is more suitable to meet the challenges in the context of global climatic changes, characterized by increasingly frequent droughts.

The data on the species diversity of representatives of the genus Teilingia Bourrelly are summarized. from the water bodies of Western Siberia, their distribution by zones and subzones. To date, 4 species and intraspecific taxa from the order Desmidiales are known for the region. Representatives of this family are found mosaically throughout the entire territory of Western Siberia. The largest number of taxa (3) was found in the middle taiga, in the tundra – two species. No species were found in the Irtysh floodplain, forest tundra, northern taiga, forest-steppe and steppe zones. In watercourses, including the Ob and Irtysh, as well as in lakes of different types, 3 taxa were identified, respectively. One species was found in swamps and in temporary reservoirs.

Nematodes are microscopic worms belonging to the soil biota with high species diversity. Nematodes have different compositions in different types of soil and areas. This research is conduct to determine the presence and genus of soil nematodes found in mustard plantations in Landasan Ulin Utara Village, Banjarbaru, South Kalimantan. Soil samples are taken from community vegetable plantations with a depth of 0-20 cm around the mustard plant rhizosphere located in ??Jalan Kurnia and Jalan Sukamara, Landasan Ulin Utara Village, Banjarbaru. Extraction to separate nematodes from soil using the Whitehead & Hemming method (1965) and nematode fixation using the Seinhorst method (1959). Furthermore, the permanent nematode preparations were made for the identification stage by morphological observations and morphometric measurements. The identification results showed that the genera of nematodes found in the study site's soil samples were Iotonchus, Crustorhabditis, Ironus, and Xiphinema.

Fish species, fishing gear and crafts in the most polluted river Buriganga were inventorial. During December, 2012 to November, 2013, a total of 56 fish species belonging to 20 families and 9 orders were recorded. Cypriniformes observed to be the most dominant order with 18 species (32%). The highest fish diversity was recorded during monsoon season, and lowest during winter. Maximum diversity variance (7.616 ± 2.76 Sd) observed in the monsoon season for 56 species (220 individuals). Also 12 different types of gears of two categories (active and passive) and two types of crafts were observed to be used for fishing in the study area. The highest number of species of fishes (n = 56) recorded in August and lowest (n = 3) in April and May 2013. Strong correlation between water depth and number of fish species (r = 0.74) and fishing activities (r = 0.96) was observed.Bangladesh J. Zool. 45(1): 11-26, 2017


The article presents the analysis of ground beetle population in forest belts of different types. The ecological structure of ground beetle complexes of forest belts is determined by soil and moisture conditions. Differences in the diversity of ground beetle populations depending on a complex of soil and plant conditions and the nature of anthropogenic impact are found. The increase in steppe formation and xerophytism conditions in forest belts leads to a decrease in species diversity of the genera Carabus, Poecilus, Pterostichus, Calathus, Amara and Harpalus.

Plant blindness is a recurrent issue in many urban green spaces. As an element of biodiversity perception, it is socially and individually determined. This paper brings up evidences of plant blindness through a quali-quantitative analysis of 49 interviews on an urban green area of the São Paulo state whose several trees have been recently plaqued. Respondents were not able to correctly identify plant elements and undervalued richness of different types of plants. Despite pointing out the necessity of green spaces in improving quality of life, respondents underestimated the importance of maintaining not only a green space, but a biodiverse one. We discuss the perception of a “good” green space is less associated with species richness, and more with passers-by expectations on a green space and with an innate plant blindness. We suppose informative plaques may play a role in reduce plant blindness, since plaques individualize plants that were once seen as components of a monotonous green landscape.
