Characteristics of Sinanodonta woodiana (Lea, 1834) Populations in Fish Ponds (Upper Silesia, Southern Poland) in Relation to Environmental Factors Abstract
We analyzed the biomass, density and age structure of S. woodiana populations in relation to different environmental factors at new sites of its occurrence in southern Poland. The highest recordedExpand
Identifying factors linked to the occurrence of alien gastropods in isolated woodland water bodies
TLDR
The aims of the study were to determine the environmental conditions that affect the existence of alien species of gastropods in this type of aquatic environment and to examine whether the occurrence of non-native species affects the community structure of the native species. Expand

TLDR
The aim was to investigate the relative importance of water chemistry in explaining snail assemblage compositions and species richness in forest ponds of contrasting pH, and found the most diverse gastropod fauna was found in neutral ponds, whereas the lowest degree of diversity wasfound in ponds with the lowest pH.

Environmental factors influencing the occurrence of freshwater snails in woodland water bodies
Studies were carried out in eight woodland water bodies that are situated in an urbanised area of Southern Poland (Upper Silesia). The aim of this study was to determine the influence of auto- andExpand
Further expansion of the invasive mussel Sinanodonta woodiana (Lea, 1834) in Poland – establishment of a new locality and population features
TLDR
It is found that S. woodiana's presence is clearly related to temperature and that the current range of its occurrence in Poland mostly overlaps with the areas with the highest average annual temperatures. Expand
The Influence of the Disturbed Continuity of the River and the Invasive Species—Potamopyrgus antipodarum (Gray, 1843), Gammarus tigrinus (Sexton, 1939) on Benthos Fauna: A Case Study on Urban Area in
TLDR
The study conducted in industrial area, in the River Ruda (Poland), showed that at the sites at which the occurrence of the two alien species was observed, the density of native benthos and diversity decreased significantly and that non-native species occurred in fast water velocity and that their presence was associated with high values of conductivity, hardness, and a high chloride content.

Substrate choice by the alien snail Ferrissia fragilis (Gastropoda: Planorbidae) in an industrial area: A case study in a forest pond (Southern Poland)
TLDR
The substrate choice by the alien snail Ferrissia fragilis (Tryon, 1863) (Phragmites australis and Typha latifolia remains, Nuphar lutea floating leaves and leaf deposit) as well as the environmental factors that influence the occurrence of this species were determined. Expand
New data on the biology and habitat preferences of the oligochaete species Ripistes parasita (Annelida: Clitellata: Naididae): a case study in a temporary woodland pond
TLDR
Characterise the environmental conditions influencing the occurrence of R. parasita and to assess its population dynamics and life history pattern and a relationship between the temperature and dissolved oxygen content in the water and the density was found. Expand
Freshwater alien species Physella acuta (Draparnaud, 1805) - A possible model for bioaccumulation of heavy metals.
TLDR
A comparison of accumulation with respect to the size classes of P. acuta indicated that the lowest metal concentration in the body was typical for the largest individuals, except for Zn, and the lowest value of bioaccumulation factor was found for the large class of specimens of this species for each metal. Expand
Autochthonic and allochthonic plant detritus as zoobenthos habitat in anthropogenic woodland ponds
  • A. Spyra

  • 21 January 2011
Regardless of origin, all water bodies situated inside forests form a unique habitat for many freshwater animals due to the allochthonous detritus covering the bottom, composed mostly of leaves fromExpand
