Abstract Phytoplankton abundance and seasonality in the northeastern Adriatic Sea were directly related to annual regime of Po River discharge period 2002–2007. In 2005, 2006, 2007, there was a shift timing maximum phytoplankton maxima from spring autumn. addition, eastern coastal area greatly influenced by oligotrophic karstic rivers Eastern Current. Dominant taxa defined on basis frequency appearance. Such an approach may help comparison communities within different environments. The...
During the June 2010 survey of phytoplankton and physicochemical parameters in Krka River estuary (eastern Adriatic Sea), a cryptophyte bloom was observed. High abundance cryptophytes (maximum 7.9×106 cells l–1) high concentrations class-specific biomarker pigment alloxanthine 2312 ng were detected surface layer at halocline lower reach estuary. Taxonomical analysis revealed that blooming species Plagioselmis cf. prolonga. Analysis environmental suggested supported by slower river flow as...
Phytoplankton in karst lakes is characterized by co-occurrence of chrysophytes (Chrysophyceae), dinoflagellates (Dinophyceae), and diatoms (Bacillariophyta) as the most diverse abundant group. Using Reynolds functional approach ecological phytoplankton investigations makes karstic comparable facilitates interpretation their responses to changing environmental conditions. Accurate taxonomic identification species level, based on precise resolution specific characteristics electron microscopy,...
Holographic microscopy has emerged as a tool for in situ imaging of microscopic organisms and other particles the marine environment: appealing because relatively larger sampling volume simpler optical configuration compared to systems. However, its quantitative capabilities have so far remained uncertain, part hologram reconstruction image recognition required manual operation. Here, we assess skill our automated processing pipeline (CCV Pipeline), evaluate size concentration measurements...
The species composition and size-structure of the phytoplankton community in Boka Kotorska Bay (SE Adriatic Sea) were analysed with respect to abundance carbon biomass, together physico-chemical parameters, aim evaluating predefined oligo-mesotrophic status this transitional water ecosystem. Three stations located inner part sampled seasonal frequency 2008/2009. Picophytoplankton cells counted using flow cytometry; nanophytoplankton microphytoplankton identified by light microscopy. relative...
Epizoic diatoms form an important part of micro-epibiota marine vertebrates such as whales and sea turtles. The present study explores compares the diversity biogeography diatom communities growing on skin shell loggerhead turtles (Caretta caretta) from four different localities: Adriatic Sea (Croatia), Ionian (Greece), South Africa Florida Bay (USA) using both light scanning electron microscopy. We observed almost 400 taxa belonging to more than 100 genera. Diatom Greece Croatia showed...
Knowledge of the importance algae in Earth's hydrosphere emerged after discovery microscope and microorganisms at beginning 18th century. Due to beauty morphological distinctiveness diatoms, majority protist research has been focused on those intriguing silicate cells. Today, vast species diversity diatoms can only be estimated, but taxa that have explored over years are stored collections represent an important resource for modern taxonomy, phylogeny evolution, ecology, paleoecology,...
The diatom genus Proschkinia is a common element of biofilms covering diverse substrata in saline inland or shallow coastal environments. It can be distinguished from other naviculoid taxa by its lanceolate valves with fistula located within the central area and numerous open girdle bands U-shaped cross-section single row perforations on internal side fold. Despite this distinct morphology, frustules are typically weakly silicified often overlooked when cleaned material analysed. current...
Abstract Background Microbial communities of wild animals are being increasingly investigated to provide information about the hosts’ biology and promote conservation. Loggerhead sea turtles ( Caretta caretta ) a keystone species in marine ecosystems considered vulnerable IUCN Red List, which led growing efforts turtle conservation by rescue centers around world. Understanding microbial how affected they captivity, is one stepping stones improving efforts. Describing oral cloacal microbiota...
Diatoms have evolved a variety of colonial life forms in which cells are connected by organic threads, mucilage pads or silicate structures. In this study, we provide the first description novel strategy colony formation among marine planktonic diatoms. Bacteriastrum jadranum loose but regular chains with distinct heterovalvate terminal cells. The and their siliceous projections, setae, not direct contact; instead, they enclosed within optically transparent matrix. This cell jacket structure...
The current study focuses on four species from the primarily marine diatom genus Craspedostauros that were observed growing attached to numerous sea turtles and turtle-associated barnacles Croatia South Africa. Three of examined taxa, C. danayanus sp. nov., legouvelloanus macewanii are described based morphological and, whenever possible, molecular characteristics. new taxa exhibit characters not previously in other members genus, such as presence more than two rows cribrate areolae girdle...
The loggerhead sea turtle is considered a keystone species with major ecological role in Mediterranean marine environment. As the case other wild reptiles, their outer microbiome rarely studied. Although there are several studies on turtle’s macro-epibionts and endo-microbiota, has been little research epibiotic microbiota associated skin carapace. Therefore we aimed to provide identification of combined eukaryotic, bacterial archaeal turtles. In this study, sampled skins carapaces 26...
The morphology of the genus Chaetoceros, one most abundant and diverse planktonic diatom groups, was investigated using material collected in eastern Adriatic Sea from 2006 to 2012. Twenty-seven morphologically distinct species have been identified both field samples cultivated strains. Two species, C. bacteriastroides pseudodichaeta, are reported for first time area. Morphometric data, general ultrastructural characters presented each based on light electron microscopy observations, with a...
The diatom genus Entomoneis is known from the benthos and plankton of marine, brackish, freshwaters. includes diatoms with a bilobate keel elevated above valve surface, sigmoid canal raphe, numerous girdle bands. Owing mostly to scarcity molecular data for diverse set species, phylogeny has not been investigated in depth. few previous studies that included were focused on broader questions available small number either unidentified or well-known species (e.g., E. paludosa). Since first...
Abstract A 275‐km‐long transversel Northern Adriatic profile from the mouth of P o R iver (Italian coast) to K varner region (Croatian coastal island area) was investigated in three successive case studies August 2008, 2009 and 2010. The short pulses ugust result surface advection riverine water, nutrients phytoplankton western eastern side driatic. This spreading exhibits inter‐annual variability depending on discharge preceding period. pulse 2010 particular resulted an extraordinary...
