The article is focused on residential suburbanization, in municipalities of the hinterland of Pilsen. The article evaluates its causes and consequences of suburbanization in the area. The main goal is to evaluate whether the spatial concentration of civic amenities of municipalities changes due to suburbanization, how the distance of municipalities from the center affects the density and diversity of civic amenities. The studied region was defined by a quantitative geographical method based on daily commutes and commutes of the population for work. The aim is to analyze the defined region and field survey in individual municipalities where the occurrence of civic amenities was determined. The article evaluates the differences in the amenities of municipalities in the hinterland of Pilsen and how suburbanization affects the civic amenities of municipalities. The research found that the distance of municipalities from the center of the region has only partial effects on the species diversity and amount of civic amenities, is that the distance from the center of the defined region affects the amount and diversity only minimally. The differences were mainly demonstrated in the structure of the newly emerging development and the effects of suburbanization on the community in the municipalities.

Abstract In April 2019, 15 (10♂, 5♀) Kerivoula bats were collected by harp traps from Xishuangbanna, Yunnan Province, China. External and craniodental examination, multivariate statistical analyses and molecular phylogenetic inference (CoI, Cytb and Rag2 gene markers) indicated they are Kerivoula kachinensis and Kerivoula titania, respectively. Former represents a new chiropteran record from China, while the latter is a valid occurrence of K. titania in this region because recent study indicate a misidentification of “K. titania” in Guangdong, Guangxi and Hainan, China. All specimens are presently preserved at Key Laboratory of Conservation and Application in Biodiversity of South China in Guangzhou University, Guangzhou, China. Nowadays, four woolly bats occur in China including, Kerivoula furva, K. kachinensis, Kerivoula picta and K. titania, whilst there is a risk of underestimation the actual species diversity in China region when comparing those of neighboring region such as Vietnam. Supports for field survey need to be continued in future.

Bryums are diverse mosses distributed widely throughout the country. The species diversity of Bryaceae which were documented in various periods has been presented here. This paper includes 82 species including three subspecies and five varieties under seven genera of the total recorded 1150 bryofloral species in Nepal so far. Besides published records, the field survey of the first author within last five years has also been included here.Key words: Bryoflora; cosmopolitan; diversity; distribution; speciesJournal of Natural History Museum Vol. 23, 2008 Page 19-26

Snakes are one of the most diverse vertebrates on the globe, mostly prefer arid zones. Nepal harbors a high unrecognized reptilian diversity. Information on the diversity and distribution of snakes in the western Nepal are derived from relatively from old literatures. This study updated the diversity and distribution of snakes from the Kaski district based on rescuing activities, field survey and literature review. Altogether 40 species of snake from five families were recorded in the Kaski district. The family Colubridae (70%) had the highest species diversity followed by Elapidae (12.5%), Viperidae (12.5%), Pythonidae (2.5 %), and Typhlopidae (2.5 %) respectively. Based on the IUCN global status of snake, 5 % are vulnerable, 5 % data deficient, 27.5 % are Least Concern and 62.5 % are Not Evaluated. Six species were found new distribution records in Kaski. Four species were the species listed on CITES II. Out of 40 species, 27.5% venomous (2.5 % were venomous but not fatal to human, 12.5% were neurotoxic, 12.5% were hemotoxic which are deadly venomous), 20% were weakly venomous and not fatal to human and 50 % were non-venomous. Habitat loss, nest destroyed, road-killed and meaningless killing by the negative perception of people was the most threat to snake in Kaski district.

The pioneer diatom study of the Early Weichselian (Valdai) sediments in Lake Ladoga basin was performed. The specifics of the diatom assemblages (co-occurrence of ecologically incompatible taxa, poor species diversity, low diatom concentration and selective preservation) suggest that during the Early Weichselian time intense erosion of previously deposited marine Eemian (Mikulino) sediments prevailed, which resulted in re-deposition of marine diatoms. The sedimentation took place in high-energy environments unfavorable for diatom accumulation and preservation.
