Earthworm Community Structure Along Altitudinal Gradients On The Western Slopes Ofkopaonik Mountain In Serbia, Filip Popovic, Mirjana Stojanovic, Slobodanka Radosavljevic, Tanja Trakic, Jovana Sekulic

Turkish Journal of Zoology

The aim of this study is to examine the altitudinal patterns of earthworm community structure at different habitat types on the western slopes of Kopaonik Mountain. In total, 30 plots between 420 and 1950 m a.s.l. were sampled within two years' fieldwork. Overall, 27 earthworm taxa belonging to 11 genera were found at the study sites. A combination of Pearson's correlation, polynomial regression, and cluster analysis (UPGMA) was used for determining the effects of altitude on the earthworm community structure. The earthworm abundance and species richness monotonically decreased with the increase in altitude, showing a significant negative correlation. Cluster analysis …


Species Diversity And Community Structure Of Zooplankton In Threedifferent Types Of Water Body Within The Sakarya River Basin, Turkey, Pinar Gürbüzer, Özge Buyurgan, Çağri Tekatli, Ahmet Altindağ Jan 2017

Species Diversity And Community Structure Of Zooplankton In Threedifferent Types Of Water Body Within The Sakarya River Basin, Turkey, Pinar Gürbüzer, Özge Buyurgan, Çağri Tekatli, Ahmet Altindağ

Turkish Journal of Zoology

The aim of this study was to identify differences between different types of water body within the same river basin by comparing the composition of the zooplankton community. The study was conducted in three types of water body in the Sakarya Basin in northwestern Turkey: an alluvial barrier lake (Lake Poyrazlar), a pond (Sorgun Pond), and a reservoir (Çubuk II Reservoir). The spatiotemporal changes of these three types of aquatic habitats were investigated in terms of the zooplankton organisms by examining their diversity, evenness, and differences in the abundance of species. A total of 81 species were identified. Thirty-eight species …


Diversity Indices Of Pelagic Rotifers In Camp Balloki Water Park, Lahore, Pakistan, Abdul Qayyum Khan Sulehria, Muhammad Anwar Malik Jan 2013

Diversity Indices Of Pelagic Rotifers In Camp Balloki Water Park, Lahore, Pakistan, Abdul Qayyum Khan Sulehria, Muhammad Anwar Malik

Turkish Journal of Zoology

This work attempted to evaluate the rotifer species diversity indices of Camp Balloki Water Park and infer the state of the water according to rotifers and physicochemical parameters. The diversity indices, species richness, and evenness were assessed every month. The Shannon–Weaver index indicated that this habitat had great diversity of rotifers throughout the year. These results were supported by the Simpson dominance, diversity, and reciprocal indices. Water and plankton samples were taken monthly from January 2006 to December 2006. In total, 38 rotifer species of 20 genera and 13 families were identified. Brachionus, Lecane, and Trichocerca dominated the locality. Rotifer …
