“…It is supposed that symbiotic α-proteobacteria participate in nitrogen metabolism. According to this concept, our observations do not confirm reports on a lack of influence of physicochemical variables of water (including sulfate concentrations) on Hirudinea communities [ 48 ]. The commonly known preference of Crustacea (mostly Gammarus) for highly oxygenated water was confirmed in our study.…”

Lake Łebsko is the largest and most productive coastal lake of the southern Baltic Sea to which it is permanently connected. The shoreline is well-developed, and the lake is divided into three parts: eastern, central, and western. Seawater intrusion affects most strongly the eastern part, where the Łeba River connects it with the sea. Samples of water and sediments were collected in 2014–2015. In the same places and time interval, bottom fauna was collected to determine the influence of environmental predictors on its qualitative-quantitative structure. Metals Cr (chromium), Pb (lead), Ni (nickel), Cu (copper), and Al (aluminium) in the samples were analyzed using inductively coupled plasma optical emission spectrometry. Most of the analyzed physicochemical variables of water were significantly higher in the eastern part: conductivity, salinity, sulfates (p < 0.0001) and chlorides (p = 0.01). Metal concentrations in water did not differ significantly between the lake parts, but in sediments they were generally higher in the western part. During the study, we detected significant changes in descriptors and abundance of the major groups of benthic fauna (Oligochaeta and Diptera), mostly between the eastern and western parts. BIO-ENV analysis showed that the benthic community of Lake Łebsko is shaped primarily by physicochemical variables of water (42% of the variance), linked with intrusion of seawater. Secondarily, the structure of the benthic community is affected by the amounts of heavy metals in sediments (31%) and water (12%). The findings can help us improve the principles of management of coastal lakes, including modification of hydrological conditions.

“…Concrete or wooden livestock troughs with hard flat bottoms are a good habitat for leeches. The accumulation of organic sediment and slowing of water could favor some prey items (oligochaeta and chironomidae larvae), thus providing good conditions for leeches (Adamiak-Brud et al, 2018). Modified springs were usually located in or close to urban areas and are vulnerable to inputs of pollutants, which reduce both water quality and habitat quality (Koperski, 2010).…”

The aim of this study was to reveal faunistic and diversity patterns and to assess the effects of environmental factors on the differentiation of leech communities. This study covers investigations of 82 karst springs in Montenegro from 2009–2017. The communities were analyzed in respect to five wellspring types – caves, sublacustrine, limnocrene, rheo-limnocrene and rheocrene. The percentage of substrate types and aquatic vegetation cover was recorded alongside water parameters. In total, 18 leech species were identified, of which two were recently described as new species for science (Dina minuoculata Grosser, Moritz and Pešić, 2007 and Glossiphonia balcanica Grosser and Pešić, 2016). K-means clustering was used to classify leech assemblages into three homogenous groups. The patterns of leech communities and the components of both alpha and beta diversity were examined in identified groups of assemblages. The significance of environmental factors and the impact of selected factors were assessed through forward selection analysis, CCA and RDA. Our results indicate that the type of spring and the environmental variables, as well as the combination of biotic and abiotic factors in a microhabitat dictate the distribution of leeches.

“…The presence of elk was also confirmed in the vicinity of the Łyna River (Poland). The occurrence of leeches from the Glossiphoniidae family is associated with the presence of s uch stable environmental elements as aquatic vegetation (Adamiak‐Brud et al, 2018 ; Kubova & Schenkova, 2014 ; Kubova et al, 2013 ; Sawyer, 1986 ). Placobdella costata prefers places in the shallowest parts of water bodies with dense vegetation (Sapkarev, 1964 ), which are also suitable for feeding all of the abovementioned potential food sources, including the zone penetrated by humans (e.g., anglers).…”
