The macro-epibiotic communities of sea turtles have been subject to growing interest in recent years, yet their micro-epibiotic counterparts are almost entirely unknown. Here, we provide the first evidence that diatoms epibionts for all seven extant species turtle. Using Scanning Electron Microscopy, inspected superficial carapace or skin samples from a single representative each turtle species. We distinguished 18 diatom taxa these individuals, with hosting at least two taxa. recommend...
Incomplete species inventories for Antarctica represent a key challenge comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, functional traits, physiological tolerances interactions, all which are fundamental disentangle different elements Antarctic biodiversity, mostly missing. However, much fauna, flora microbiota emerged ice-free land continent have an uncertain presence and/or...
Although the sea turtles have long been familiar and even iconic to marine biologists, many aspects of their ecology remain unaddressed. The present study is first epizoic diatom community covering olive ridley turtle's (Lepidochelys olivacea) carapace describing diatoms living on in general, with primary objective providing detailed information turtle epibiotic associations. Samples including associated biofilm macro-fauna were collected from Ostional beach (9° 59´ 23.7´´ N 85° 41´ 52.6´´...
Marine mammals such as whales and dolphins have been known for a long time to host very specific epizoic community on their skin. Less however is the presence of similar carapaces sea turtles. The present study first describing new taxa inhabiting turtle carapaces. Samples, collected from nesting olive ridley turtles (Lepidochelys olivacea) Ostional Beach (Costa Rica), were studied using light scanning electron microscopy. Two unknown small-celled gomphonemoid analysed in more detail are...
Despite recent advances in polar marine biology and related fields, many aspects of the ecological interactions that are crucial for functioning Antarctic shallow water habitats remain poorly understood. Although epiphytic diatoms play an essential role food web, basic information regarding their ecology, biodiversity biogeography is largely unavailable. Here, we synthesise studies on Ross Sea collected during 11 summer expeditions between years 1989/90 2011/12, presenting a full list diatom...
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...
SUMMARY Seasonal studies of water bodies in separate branches the Vistula River estuary Northern Poland were conducted over 30 months from May 2005 to October 2007. Diatom samples collected different substrata two sites located river mouth, which has physical characteristics as a result complex interplay natural and human influences that have taken place last 100+ years. The diatom flora growing on hard surfaces near banks such sand, muddy rocks, macroscopic green algae and/or vascular...
Diatom shells are a natural, theoretically unlimited material composed of silicon dioxide, with regular patterns pores penetrating through their surface. For characteristics, diatom show promise to be used as low cost, highly efficient drug carriers, sensor devices or other micro-devices. Here, we demonstrate functionalized gold nanoparticles for the harvesting and detection biological analytes (bovine serum albumin—BSA) chemical pollutants (mineral oil) in abundance ranges, applications...
Secretome of primary cultures is an accessible source biological markers compared to more complex and less decipherable mixtures such as serum or plasma. The protonation state (PS) secretome reflects the metabolism cells can be used for cancer early detection. Here, we demonstrate a superhydrophobic organic electrochemical device that measures PS in drop derived from liquid biopsies. Using data sensor principal component analysis (PCA), developed algorithms able efficiently discriminate...
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 Epiphytic diatoms are important constituents of the Southern Ocean coastal water ecosystem, being a key element in many Antarctic trophic chains. However, only limited information exists relating to these microalgal communities. Here we describe our findings study on epiphytic from Terra Nova Bay (Ross Sea, Antarctica) based material collected during summer campaigns spanning 1990–2004. Observations associated with three rhodophyte species ( Iridaea cordata (Turner) Bory,...
Abstract It has been known for a long time that marine mammals, such as whales and dolphins, host very specific epizoic community on their skin. Whether or not similar exists the carapaces of sea turtles is less studied. The present paper describes two new diatoms from genus
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...
