The southern blue-ringed octopus, Hapalochlaena maculosa (Hoyle, 1883) lacks a planktonic dispersal phase, yet ranges across Australia's southern coastline. This species' brief and holobenthic life history suggests gene flow might be limited, leaving distant populations prone to strong genetic divergence. This study used 17,523 genome-wide SNP loci to investigate genetic structuring and local a...

Haptophytes are nano-planktonic unicells whose small size belies their contribution of 30-50% of the total photosynthetic stock in the world's ocean [1]. In addition to their major role in contributing to the Earth's carbon cycle [1], blooms of these algae can produce noxious odors that compromise water quality and can generate toxins responsible for fish and animal mortality [2]. Because the f...

This pilot study presents surface sediment diatom assemblages in four alpine lakes the Zelengora Mountains. The are distributed across an treeline, spanning temperate mixed forest and treeless tundra zones, thus offering excellent opportunity to interaction of physicochemical properties biotic communities different lake settings. A total 52 taxa from 28 genera were identified, with only one tax...

BACKGROUND The bacterial taxon Polynucleobacter necessarius subspecies asymbioticus represents a group of planktonic freshwater bacteria with cosmopolitan and ubiquitous distribution in standing freshwater habitats. These bacteria comprise <1% to 70% (on average about 20%) of total bacterioplankton cells in various freshwater habitats. The ubiquity of this taxon was recently explained by intra-...

Although planktonic algae are a basic component of freshwater ecosystems, studies on their diversity and species distribution still not in satisfactory numbers. This study aims to contribute Turkish algal flora particularly with the new records reported. A total 158 Charophyta taxa were determined conducted from 2017 2019 25 river basins Turkey. In this study, while highest taxon was found Saka...

The investigated section cropping out in Kuh-e-Banesh, Zagros basin (southern Iran) is represented by limestone, Cherty beds and marllevels bearing abundant Planktonic foraminifers, radiolarian microfaunas, and ammonite imprints. For the first time, well to moderatelypreserved forms of Planktonic foraminifera have been extracted from black shale and marls levels. Extracted biota was studied wit...

conclusions bacterial resistance against chlorhexidine is increasing. sub-mic doses of chlorhexidine digluconate can stimulate the formation of biofilm strains. materials and methods forty clinical isolates of escherichia coli, salmonella serotypes, staphylococcus. aureus and streptococcus agalactiae (10 isolates for each) were examined for chlorhexidine digluconate effects on biofilm formation...

We provide a biochronology of Jurassic planktonic foramininfera, using first order linkage to ammonite and nannofossil stratigraphy geochronology. This enigmatic understudied group microfossils occurred from middle Toarcian through Tithonian time, ~180 ~143 Ma; its origin is unknown. There are three genera: Globuligerina, Conoglobigerina Petaloglobigerina. The genus with smooth pustulose test s...
