Planktonic ciliate species form multiple trophic guilds and are central components of freshwater food webs.Progress in molecular analytical tools has opened new insight into ciliate assemblages.However, high and variable 18S rDNA copy numbers, typical for ciliates, make reliable quantification by amplicon sequencing extremely difficult.For an exact
The discovery of an isolated Hooded Tech Tee juvenile tooth of an extinct lamnid shark Cosmopolitodus hastalis (Agassiz, 1843) from the Duho Formation (middle Miocene), Pohang City, South Korea.This tooth is approximately 11 mm in crown height, suggesting a juvenile affinity of an individual this tooth originated.In life, the shark is estimated to
Abstract The results show the morphological analyses and spectroscopic studies of snow and glacier algae and their parasitic fungi in Svalbard (High Arctic).Fixed algal cells of two species, Sanguina nivaloides and Ancylonema nordenskioeldii, were imaged using light microscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM).F
