The aim of this study was to examine the effects of exposure to Zn (14 and 72 mg/L) and Cd (7.7 and 77 mg/L) for 24 and 48 h on oxidative and antioxidative parameters and the activity of glutathione-S-transferase in Artemia franciscana...

Due to its geographical position, relief features, specific geological past and great heterogeneity of space in a relatively small area, Bosnia and Herzegovina has specific hydro-morphological features, with numerous spring habitats and unique aquatic biodiversity, mainly composed by stenothermic and relict taxa. Spring habitats, as well as the flo...

The ecology of springs of the southeastern part of Serbia is poorly studied. The present chapter is planned as the first step towards the inventory and characterization of springs in this region. In this chapter we present the results of the investigation of macroinvertebrate communities of two groups of springs, in the valley of Niš and the Vlasin...

Riparian springs bordering streams, rivers and lakes are under strong influence of flooding events, and therefore more sensitive to the ongoing climatic changes. However this type of habitats is still commonly neglected in limnological literature. This chapter presents modern knowledge on these habitats gained in recent years by researching the rip...

Ramsar site “Bardača Wetland” has been on the list of wetlands of international importance since 2007.

Spring ecosystems are exceptionally threatened and their conservation is often emphasized due to high levels of endemism among the groups inhabiting these ecosystems. This study includes gastropod assemblages of 36 springs situated in the northwestern part of Bosnia and Herzegovina. The aims of this paper were: to determine key factors for distribu...

Despite their comparative richness and accessibility in the Republic of Srpska and in Bosnia and Herzegovina in general, population studies of reptiles have not been performed in Srpska until recently. For example, one of the most common snake species in this area is the dice snake; nevertheless, previous studies have only reported its distribution...

• Springs are distinct freshwater habitats that are threatened globally by human impacts, but are not included in standard freshwater assessment tools. This study analysed how the standard macroinvertebrate metrics currently used in biomonitoring programmes for running waters perform in springs with similar ecological qualities but with a different...

Sarajana apfelbecki (Brancsik, 1888) was assigned by Radoman to the monotypic genus, closely related to Belgrandiella Wagner, 1927. Later the distinctness of the genus Sarajana was questioned, and S. apfelbecki classified within the genus Belgrandiella. Our study on Sarajana from five localities in Bosnia and Herzegovina including Vrelo Bosne (type...
