Scanning Electron Microscopic (SEM) study requires an expensive, complicated and timeconsuming method for sample preparation of aquatic invertebrates. In this paper a simplified sample preparation technique without dehydration, critical point dry, for SEM study of Bosmina tripurae was proposed. The present investigation included detail morphology of different life history stages of this cladoce...

The impact of mosquito control on nontarget organisms using Abate-4-E was investigated in terms of immediate mortality and residual activity. Three 10 year old, man-made ponds having similar community structures and population densities were studied. The residual activity, determined by bioassays with 4th instar Aedes communis, was significantly longer in a relatively cooler pond. Populations o...

This study focused on monthly densities and abundance of planktonic microcrustaceans (Cladocera Copepeda) in K?rklareli reservoir, as well their relationship with some physicochemical parameters at three different stations for the period from May 2018 to April 2019. In present study, a total 26 species, 14 Cladocera 12 Copepoda were identified. The most common species reservoir B. longirostris,...

the invertebrate communities of the northern chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. the river systems located in the atacama desert are endorheicand are affected by the rainy period of january-february commonly known as the “bolivian winter“. the present study isthe first report on the observations of arthropods...

Astyanax cocibolca, a small filter-feeding species is a new characid species endemic to Lake Nicaragua. It is distinguished from the syntopic Astyanax aeneus by its high gill raker count, slender body, upturned snout, long maxillary bones, conical outer premaxillary teeth, lower number of scales above lateral line, more intense black lateral band, smaller size, and trophic niche partitioning. A...

The present work aims to study the Zooplankton seasonal distribution and diversity in Karanja reservoir, Bidar district for the period of two years from October 2001 to September 2003. We have recorded 36 species of which, 15 species belongs to rotifera, 11 species belongs to cladocera, nine species belongs to copepoda and ostracoda three species. Among zooplankton, particularly rotifera was th...

The aim of the present study is to represent an annotated checklist of the Branchiopoda (Crustacea) reported from Chilean inland waters. Only Anostraca and Cladocera are found in Chile, while there are no reports on Notostraca and "Conchostraca". Our checklist contains 85 valid taxa, among which nine anostracans and 76 cladocerans. Such "low" biodiversity of the branchiopods in Chile is in real...
