This paper describes a new species of Halamphora – Halamphora lombokensissp. nov. and records for the first time Halamphora banzuensis for the coasts of Indonesia. The study utilized light and scanning electron microscopy to meticulously examine the morphology. These species were found at Kuta Beach on the island of Lombok in Indonesia in highly sa...

Two new Halamphora (Amphipleuraceae: Bacillariophyta) species from Aydar-Arnasay system of Lake in Uzbekistan)

Cyprinus carpio is one of most produced fish species farmed in Turkey. There are many factors comprising with the viral diseases that reduce productivity and cause significant economic losses in carp production. Epithelioma papulosum cyprini (EPC) is of the viral diseases with high infection and mortality rates. For prevention of parasitic diseases...

Psychrophile diatoms in Turkiye

Diversity of Halamphora (Diatomae)

Rare or poorly known diatoms in Salda lake

The Erg Er Raoui is located in the northwestern part of the Algerian Sahara. In the region, numerous inter-dune depressions are marked by Holocene lacustrine sedimentation (detrital layers overlain by white biogenic carbonates containing diatoms). The samples were collected from the depressions by scraping the surface of the hills. The samples were...

In order to determine the water quality of Susurluk Stream, Çapraz Stream and Karadere, 5207 macrobenthos samples were collected and examined from 14 different stations in two different periods of 2021, and 37 families (Baetidae, Caenidae, Corixidae, Gerridae, Naucoridae, Nepidae, Hydrometridae, Pleidae, Mesovelidae, Coenagrionidae, Libellulidae, C...

The current article describes Navicula vanseeasp. nov., a new species of diatom from Lake Van, a highly alkaline lake in Eastern Anatolia (Türkiye). The description is based on light and scanning electron microscopy performed on two monoclonal cultures. The complete nuclear rRNA clusters and plastid genomes have been sequenced for these two strains...

Tunceli ili Pülümür ve Ovacık ilçelerindeki Ephemeroptera (Insecta) faunasını tespit etmek amacıyla Mart 2019-Temmuz 2020 tarihleri arasında 11 istasyondan 2142 nimf örneği toplanarak incelenmiş ve 5 familyaya ait 10 cinse bağlı 22 takson tespit edilmiştir. Çalışma sonucunda tespit edilen Baetis (Baetis) vernus, B. (B.) lutheri, B. (B.) pavidus, B....

Kaçkar Mountains is located in the Eastern Black Sea Region in Türkiye. The mountainous area includes granite and volcanic rocks influencing water conditions. Moçar Lake is located at 40°42'35'' N and 40°54'51'' E in the Verçenik Valley with an altitude of 3.060 m. a.s.l. The samples were collected in July 2015 from epilithic and epipelic substrata...

Although studies on the order Ephemeroptera are at a sufficient level in many of the provinces in the Aegean region, there is no comprehensive study on the provinces of Aydın and Denizli. Until now, four species from Aydın and two species from Denizli province have been reported from the Ephemeroptera order. The research being done in these provinc...

Cold environments are considered extreme biomes and historically thought to be barren and unproductive. However, investigations show that some of the coldest regions in the world represent unique biodiversity hotspots. In this review, the prominent diatom communities of alpine lakes and ponds across different parts of the world, including the Arcti...

In order to evaluate the macrozoobenthic fauna of Çıldır, Aktaş and Aygır lakes, 47 taxa were identified as a result of the samplings carried out in different periods in 2013, 2017 and 2019. 41 of 43 taxa identified at species level were new records for the study area. The dominant species of Lake Çıldır were Gyraulus (Armiger) crista (4.49%), Para...

This paper presents the first scanning electron microscope documentation and valve ultrastructure description of the rare species Craticula vixvisibilis var. distinctior Lange-Bertalot, and a description of the new species Craticula anatoliana sp. nov. Both species occurred in high electrolyte content, brackish maar-type lakes in the Inner Anatolia...

In this study, acute toxicity effects of copper on the fibroblast cells and body wall structures of medicinal leech (Hirudo verbana) were characterized by using light microscope and transmission electron microscope (TEM). For this purpose, live medicinal leech specimens were treated with 0.2 mg Cu 2+ /l concentration for 96 hour. The samples were f...

Hydroscapha granulum is the only species belonging to family of Hydroscaphidae from Turkey. In this study, Hydroscapha granulum (Motschulsky 1855) samples belonging to Myxophaga subordo were collected from five different localities and taxonomical characteristics of the specimens were compared with the specimens in literatures. Differences in some...

In this study, 3801 Ephemeroptera specimens were collected and identified from the Gediz River basin (Kütahya, Manisa, Uşak, and İzmir provinces) during 2011–2012. Twenty-three taxa belonging to 14 genera from 5 families were determined. All identified species from Uşak, Manisa, and İzmir and the 4 identified species from Kütahya are new records fo...

Two new species of Ochthebius Leach (Coleoptera: Hydraenidae) are described from Turkey: O. (s.str.) halophilus (Kırıkkale Province) and O. (Asiobates) arator (Kütahya and Uşak Provinces). The former is the first member of the Ochthebius (s.str.) notabilis species group from Turkey, and the latter belongs to the O. (Asiobates) bicolon group. Both o...

A checklist of the Hydraenidae recorded from Turkey is presented. The checklist includes data on the distribution and relevant references for 210 species/subspecies: two Aulacochthebius Leach, 113 Hydraena Kugelann, 21 Limnebius Leach, and 74 Ochthebius Leach. On the basis of their current distribution, the established 210 species/subspecies can be...

In this study, acute toxicity effects of copper on the fibroblast cells and body wall structures of medicinal leech (Hirudo verbana) were characterized by using light microscope and transmission electron microscope (TEM). For this purpose, live medicinal leech specimens were treated with 0.2 mg Cu 2+/1 concentration for 96 hour. The samples were fi...

5194 samples from 78 localities were collected between 2004 and 2006 to investigate the Hydraenidae (Coleoptera) fauna of South Marmara Region inTurkey. 31 species and 1 subspecies belonging to 3 genera were determined. Of identified species L. (s.str.) rubropiceus, Ochthebius (s.str.) difficilis, O. (s.str.) fausti, O. (s.str.) inconspicuus, O. (s...
