“…The species found in equilibrium states in this study are either stresstolerant or K-selected ones with low net growth rates in agreement with observations on phytoplankton Stoyneva, 2003). In our study, steady state did not occur during the colonization periods (when the diversity was low) in contrast of Hameed's (2003) study, where, paradoxically, the equilibrium state was suggested during the colonization period.…”

This paper analyses the establishment of equilibrium states in relation to natural disturbances in epilithic diatom assemblages. Sterilized limestone bricks were exposed between April 2008 and 2009 in the Torna-stream and were removed one by one on every third day in the first month and then weekly until May 2010. Physical and chemical parameters were measured on the field and in laboratory. Equilibrium states were restricted to three separate

“…Apart from algae filling the inter-stem spaces, the food particles consist of a variety of protozoans, bacteria, and detritus. Typical littoral food, consisting of periphytic communities overgrowing the plant surfaces, may greatly depend on the specificity of macrophyte shoot complexity (Ács et al, 2003;Albay and Akcaalan, 2003;Hameed, 2003).

Chydorus sphaericus, a cladoceran characterized by a wide range of distribution, is often numerous in various water habitats. Its body size is a consequence of environmental characteristics and physiology. The aim of the study focused on the distribution of body size and densities of C. sphaericus in relation to environmental conditions represented by: (i) habitat types (elodeids, helophytes, and the open water); (ii) specific pond types (forest and field); (iii) pond size (surface area); (iv) the presence/lack of fish; and (v) physicochemical factors. Similar to large daphnids, in the case of the examined small water bodies, fish presence was responsible for a reduction of the body size of C. sphaericus in the zone of open water. More abundant crustacean communities and the presence of larger specimens were found among macrophytes, which indicated that aquatic vegetation offered optimal growth conditions as well as an effective refuge against fish predation. These facts reflect the necessity for maintaining a varied mosaic of habitats even in small water bodies such as the examined ponds. We found that not only the abundance of C. sphaericus but also its body size can be used as an bioindicator of environmental conditions as it preferred small and eutrophic ponds, particularly those with complex macrophyte cover (such as elodeids). Furthermore, the abundance pattern of zooplankton dominant species was affected by elodeids and fish presence as well as by the area of the ponds.

“…However, macrophytes constitute a vast substrate for the growth of periphytic communities (Messyasz & Kuczyńska-Kippen 2006). Periphyton is a biological layer found in various substrata in natural waters and consists of a mucilage of slime, bacteria, algae, fungi, protozoa and small metazoans (Hameed 2003). Many recent studies have shown that ciliates play a very important trophic role in periphytic communities, and as an indication of the degree of pollution in rivers and lakes (Primc-Habdija et al 2000, Mieczan 2005a).…”
