Abstract
We investigate geographic patterns of coral bleaching in 1998 and 2002 and outline a synergism between heat stress and nutrient flux as a major causative mechanism for those patterns. The study provides the first concrete evidence for the oft-expressed belief that improved coral reef management will...

Abstract
The abundance, biomass, size distribution, and taxonomic composition of bacterial and protistan (heterotrophic and autotrophic nanoflagellates and ciliates) communities were investigated in six lakes of Masurian Lake District (north-eastern Poland) differing in trophic state. Samples were taken from...

Abstract
We examined the inhibitory effects of protein tyrosine phosphatase (PTPase) inhibitors, including sodium orthovanadate (SOV), ammonium molybdate (AM), and iodoacetamide (IA), on cell growth, accumulation of astaxanthin, and PTPase activity in the photosynthetic algae Haematococcus lacustris. PTPase...

Abstract
The influence of the number of repeating units in self-assembled monolayers (SAMs) of ethylene glycol and of their end-group termination on the settlement and adhesion of two types of algal cells, viz., zoospores of the macroalga Ulva and cells of the diatom Navicula , was studied. The findings are...

Abstract
Common Anabaena and Calothrix cyanobacteria and Klebsormidium green algae are shown to form intracellularly akaganeite beta-FeOOH nanorods of well-controlled size and unusual morphology at room temperature. X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron micros...

Abstract
After the ban of tributyltin (TBT) for vessels not longer than 25 m in 1986, Irgarol has become a commonly used antifouling biocide. Irgarol is highly toxic to autotrophic organisms and has the potential to accumulate in organic material. In the literature, environmental concentrations of Irgarol up...

Abstract
Nowadays, a wide variety of compounds such as polyphenols, polyunsaturated fatty acids (PUFA), or phytosterols obtained, for example, from wine, fish byproducts, or plants are employed to prepare new functional foods. However, unexplored natural sources of bioactive ingredients are gaining much atte...

Abstract
We compared solid-phase microextraction (SPME) and membrane-assisted solvent extraction (MASE) for the detection of 2-methylisoborneol and geosmin in aqueous samples. SPME is the most sensitive of these techniques with a limit of detection of 25 parts-per-trillion for 2-methylisoborneol and 10 parts...

Abstract
We present a detailed analysis of pattern formation in this RDA model. We derived the conditions for differential-flow instability that cause the formation of spatial patterns, and then systematically investigated how these patterns depend on model parameters. We also present a detailed study of the...

Abstract
We report an FTIR spectroscopic technique combined with intracrystalline deuteration and rehydrogenation of cellulose samples to investigate the localization of I(alpha) and I(beta) domains within a cellulose microfibril obtained from I(alpha)-rich algae. When Glaucocystis cellulose incompletely con...

Abstract
We performed controlled laboratory experiments to investigate the effect of phytoplankton biodiversity on phytoplankton stoichiometry. Our results indicate that biodiversity influences carbon assimilation and nutrient uptake of phytoplankton communities in different ways, resulting in variations of...

Abstract
The percent removal and uptake of Pb2+ by algal-consortium (CP1) developed from wastewater of biological oxidation pond (Wazirabad, New Delhi, India) was studied under batch conditions with live biomass compared with continuous system using dried biomass immobilized on silica under laboratory condit...

Abstract
We highlight the chemistry and biology of vanadium-dependent haloperoxidases from fungi and marine algae and the emergence of new bacterial members that extend the biological function of these poorly understood halogenating enzymes....

Ecological Applications (19)5 2009
Abstract
We tested whether human activities on land can increase subsidies of terrigenous nitrogen to open rocky coasts and whether these differences can predict apparent deforestation of kelp forests. We first identified landscape-scale variation in the human-mediated transfer of dissolved inorganic nitroge...

Abstract
Current methods to remove algae from a liquid medium are energy intensive and expensive. This study characterized algae contained within a wastewater oxidation pond and sought to identify a more efficient harvesting technique. Analysis of oxidation pond wastewater revealed that algae, consisting pri...

Abstract
We studied four small unproductive lakes in subarctic northern Sweden during one summer season. The production of new biomass in both benthic and pelagic habitats was calculated as the sum of autotrophic production by algae and heterotrophic production by bacteria using allochthonous organic carbon...

Abstract
Dunaliella salina has been exploited as a new type of bioreactor due to its unique advantages. However, this bioreactor application was restricted for absence of a high-efficiency and stable transformation method at present. In the present study, the cells of D. salina were transformed by glass bead...

Abstract
We outline how the niche construction and contemporary evolution interact to alter the direction of evolution and the structure and function of communities and ecosystems. We then present five empirical systems that highlight important characteristics of eco-evolutionary feedbacks: rotifer-algae che...

Abstract
The changes imposed by dams on hydrological regime, water transparence and nutrient concentrations downstream affect biodiversity in relation to species richness and specific composition of the community. The aim of this work was evaluate this effect on periphyton, comparing richness and composition...

Abstract
We honor Lawrence Rogers Blinks (1900-1989) in this tribute. We introduce his scientific life that started at the Harvard University, and ended at the Hopkins Marine Station of Stanford University. We discuss his pioneering contributions in the areas of ion transport in membranes and of photosynthes...

Abstract
Empirical data providing evidence for a colimitation of an herbivore by two or more essential nutrients are scarce, particularly in regard to biochemical resources. Here, a graphical model is presented, which describes the growth of an herbivore in a system with two potentially limiting resources. T...
