Testing non-typified names by applying rules of circumscriptional nomenclature shows that in most cases the traditional usage can be supported. However, the original circumscription of several widely used non-typified names does not fit the taxa they are applied to. Here I discuss names historically applied to the taxa whose correct circumscriptional names should be Hexapoda, Amyocerata, Triplu...

Planktonic and sessile susceptibilities to micafungin were determined for 30 clinical isolates of Candida albicans obtained from blood or other sterile sites. Planktonic and sessile MIC(90)s for micafungin were 0.125 and 1.0 microg/ml, respectively.

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...

Sediments from Tibetan lakes in NW China are potentially sensitive recorders of climate change and its impact on ecosystem function. However, the important plankton members in many Tibetan Lakes do not make and leave microscopically diagnostic features in the sedimentary record. Here we established a taxon-specific molecular approach to specifically identify and quantify sedimentary ancient DNA...

Over the last few decades, rising greenhouse gas emissions have promoted poleward expansion of the large-scale atmospheric Hadley circulation that dominates the Tropics, thereby affecting behavior of the Intertropical Convergence Zone (ITCZ) and North Atlantic Oscillation (NAO). Expression of these changes in tropical marine ecosystems is poorly understood because of sparse observational datase...

This report describes the discovery of the rare euglenoid taxon Trachelomonas bituricensis var. lotharingia in a small mesotrophic pond in the Czech Republic. Only limited data are available on the distribution of this taxon as same as for typical variety of Trachelomonas bituricensis, even though this taxon is morphologically very well defined. I provide a brief discussion of the taxonomic val...

The influence of resource availability on planktonic and biofilm microbial community membership is poorly understood. Heterotrophic bacteria derive some to all of their organic carbon (C) from photoautotrophs while simultaneously competing with photoautotrophs for inorganic nutrients such as phosphorus (P) or nitrogen (N). Therefore, C inputs have the potential to shift the competitive balance ...

ECCMID08_R2330: Contact View [R2330] Effect of farnesol on planktonic versus biofilm cells of Staphylococcus epidermidis F.I. Gomes, R. Oliveira, P. Teixeira. (Braga, PT) Objectives: Staphylococcus epidermidis is the most frequent cause of nosocomial sepsis and catheterrelated infections, in which biofilm formation is considered to be the main virulence mechanism. Quorumsensing system have been...

As coral bleaching events become more frequent and intense, our ability to predict and mitigate future events depends upon our capacity to interpret patterns within previous episodes. Responses to thermal stress vary among coral species; however the diversity of coral assemblages, environmental conditions, assessment protocols, and severity criteria applied in the global effort to document blea...

Shells of planktonic foraminifera recovered from marine sediments provide a multitude of important palaeoproxies. Most of these proxies are based on the assumption that each morphospecies of planktonic foraminifera represents a genetically continuous species with a unique habitat. Recent discovery of hitherto hidden genetic diversity among modern planktonic foraminifera has significant repercus...
