Vertebrate fauna of the Toruń Valley
نویسندگان
چکیده
Being a mosaic of miscellaneous habitats, the Toruń Valley is a refuge for numerous species of animals, who find their shelter here, food and favourable places for reproduction. Countrywide, the Valley is also an important natural ecological corridor for those animals. Regarding this function, the Vistula River is of particular significance within the described area. This study presents species of wild animals from all taxonomic groups of vertebrates, which occur in the Toruń Valley. Apart from the list and the total number of species in individual taxa of higher rank, short descriptions of habitat requirements were provided together with the information on changes in the population resources of some major species. More attention was devoted to species, which withdrew from this area, as well as to those which were subject to the process of restoration. More space in the text was also dedicated to those species of vertebrates, which occur in frequent mosaics of heaths, psammophilous grasslands and encroaching pine forests. In the paper, the attention was also directed to threats posed to fauna by a hydrotechnical investment undertaken on the Vistula River upstream from the city of Toruń, as well as to the significance of Natura 2000 areas legislated in the Toruń Valley for the protection of species and habitats.

متن کاملWater, Rather than Temperature, Dominantly Impacts How Soil Fauna Affect Dissolved Carbon and Nitrogen Release from Fresh Litter during Early Litter Decomposition
Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone ...

In this paper we report about 88 longhorned beetles (Cerambycidae) species found in 6929 hectares and distributed along an altitudinal gradient of 1500 m of an Italian alpine valley (Val Genova, central-eastern Italian Alps). The species richness, result merging data from sixty years (1947-2007) of entomological surveys, corresponds to the 32% of the Italian cerambycid fauna confirming the high...
