Two new algal species, namely, Prasiola calophylla (Prasiolaceae), and Closterium navicula (Closteriaceae) were collected from west coasts of the Caspian sea (Mazandaran province, N Iran), and runoff in south Tehran, respectively. Both the species were analyzed on the bases of morphological and anatomical characters and were determined using identification keys and interspecific comparison. Pra...

The involvement of algal chemical cues in the pre-ingestive selection of food particles in Crassostrea gigas was studied using a new approach. Live cells of two microalgal species, Nitzschia closterium and Tetraselmis suesica, were separately entrapped in small alginate microcapsules using an emulsification/internal gelation method. Microcapsule size was adjusted to be within the range of parti...

An appraisal of the current ecological status Asejire Reservoir was carried out using reservoir phytoplankton composition and community structure. Monthly sampling in nine selected sites for twelve months. Data were analysed descriptive statistics, analysis variance, Shannon-Weiner Evenness indices. One hundred fifty-four taxa identified. Taxa dominance following order: Bacillariophycea>Chlorop...

Abstract The benthic algal composition of Charophyta in the Avusor Great Lake and Koçdüzü at altitude about 3,000 m a.s.l. was investigated on 21 August 2019. A total 112 species, belonging to Zygnematophyceae, were identified. genera Cosmarium (44), Staurastrum (16), Closterium (15), Euastrum (13) most abundant. members filamentous charophyta represented by two species. Bioindicator species ch...

Abstract Benthic diatoms dominate primary production in marine subtidal and intertidal environments. Their extraordinary species diversity ecological success is thought to be linked with their predominantly heterothallic sexual reproduction. Little known about pheromone involvement during mating of pennate diatoms. Here we describe guided the coastal raphid diatom Cylindrotheca closterium . We ...
