Microplastic (MP) contamination is considered a growing problem in terms of its production and observed impacts on aquatic organisms. In this study, we investigated the adverse effects that could occur from pure polyethylene (PE) MPs PE contaminated with phenanthrene (Phe) chlorpyrifos (CPF) D. magna podocopid ostracods. The organisms were exposed to different sizes (1–5, 27–32, 45–53, 212–250 ...

Since 1928, Henri Gauthier has been the only zoologist to describe the extant non-marine ostracod fauna of Tunisia. In 2010, new samples of living non-marine ostracods were collected from central and southern Tunisia. A complete list of the 41 non-marine ostracods of Tunisia is presented, including the species of Gauthier's work, published Holocene records, and new results from our field study....

The anthropogenic deposition of sediment on previously undisturbed areas has a profound effect on species diversity and density. This is particularly true in the remarkably clear and productive Lake Tanganyika. The effects of sediment in Lake Tanganyika have been seen for fish, molluscs and ostracods (Alin et al. 1999; Cohen 1993). The Lake Tanganyika Biodiversity Project identified excess sedi...

Ancient asexual animal groups, such as bdelloid rotifers and darwinuloid ostracods, are excellent model organisms to study the effects of long-term asexuality. However, the absolute length of time that these groups have been fully asexual is mostly ignored. In the case of the darwinuloid ostracods, the fossil record shows that sexual reproduction disappeared almost completely after the end of P...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...

Biodiversity databases are changing the longevity of data in era open science. They also represent a collaboration opportunity analyzing large-scale (paleo)biological patterns beyond local project or time scale. Ostracods, microscopic crustaceans, component many biodiversity databases. live most kinds aquatic environments today and their fossil record spans nearly whole Earth's metazoan biosphe...
