The millipedes from several types of environment in Roztocze (SE part of Poland) have been studied. 14 species of Diplopoda have been collected from 9 types of habitats.
Currently, the alternative forms of management are increasingly applied in agriculture. Although their less negative impact on environment is generally supposed, there is still a lack of a reliable data about their real favourability for the abundance and diversity of soil invertebrates, including millipedes. Therefore, the aim of our study was to find out, whether the form of agricultural management affects the structure of millipede communities and hence, the performance of their functions in soil ecosystems. The research was carried out using pitfall trapping through growing seasons 2005 to 2007 on the model territory of Agricultural Cooperative (AC) Očová (Central Slovakia). Millipedes were captured at four pairs of sites (8 sites in total). The same cultivated crop (wheat, barley, alfalfa or permanent law) with application of two different forms of agricultural management (conventional form and sustainable form with basic sustainable agro-environmental scheme) was characteristic of each pair of sites. The research results disclosed that the management form plays a significant role, especially in such agrocoenoses, in which the same crop is cultivated for several years (e.g. sites with alfalfa or permanent lawn), i.e., on the sites without ploughing or other similar agrotechnical measures. In these cases, the sites with the sustainable agro-environmental scheme had higher species richness (8 and 9 species) and higher total abundance of millipede communities (2.2 and 5.7 ind. collected per one day and one trap) than the sites with the conventional form of agrotechnical management (5 and 5 species, 0.09 and 0.3 ind. collected per one day and one trap). In order to obtain a more detailed knowledge about the impact of agricultural management forms on millipede communities, this kind of research should be carried out in different conditions (other crops, soil conditions, climate zones, etc.) as well.
Nannorrhacus parvus sp. n. from Martinique, only the 2nd congener, is just the 4th species of the family Platyrhacidae to be found in the Antilles. It differs from N. luciae (Pocock, 1894), from St. Lucia, Lesser Antilles, by the following characters: a smaller size; presence of 3 or 2 transverse rows of larger setigerous tubercles on collum and postcollum metaterga, respectively; absence of areations on metaterga; far more strongly tuberculate lateral edges of paraterga; ventrolateral location of ozopores; underdeveloped pleurosternal carinae; and shorter and stouter gonopods.
Two new, obviously high-montane, forest-dwelling species of the large eastern Palaearctic genus Epanerchodus are described from China: E. belousovi sp. п., from Sichuan, and E. typicus sp. п., from Yunnan. Both differ from congeners chiefly by certain details of gonopod structure.
Diplopoda of pine forests (Vaccinia myrtilli-Pinetiun] have been studied in five forest areas situated in various zoogeographical regions of Poland. An analysis of species composition and structure of Diplopoda communities has been performed. The analysis includes fluctuations of the above characteristics between Diplopoda communities inhabiting forests with various degrees of transformation from the natural state, as well as fluctuations caused by zoogeographical and phytosociological factors.
