Remote Detection of Marine Microbes,Small Invertebrates,Harmful Algae,and Biotoxins using the Environmental Sample Processor (ESP)
Marine Microbes Small Invertebrates Harmful Algae Biotoxins using the Environmental Sample Processor
2015/7/3
The advent of ocean observatories is creating unique opportunities for deploying novel sensor systems. We are exploring that potential through the development and application of the Environmental Samp...
An experimental analysis of harmful algae–zooplankton interactions and the ultimate defense
harmful algae–zooplankton interactions the ultimate defense
2014/4/4
We examined effects of the invasive, toxigenic haptophyte Prymnesium parvum on grazing rates, feeding
behaviors, and life-history characteristics of clonal lineages of three daphniid zooplankton spec...
Quantifying phosphorus and light effects in stream algae
Quantifying phosphorus light effects stream algae
2014/4/17
Simultaneous gradients of phosphorus and light were applied in experimental streams to develop quantitative
relationships between these two important abiotic variables and the growth and composition ...
Carbon sequestration and stoichiometry of motile and nonmotile green algae
Carbon sequestration nonmotile green algae
2014/4/17
Actively motile, flagellated phytoplankton taxa often exploit vertical gradients in the availability of light and
nutrients. The ability to move actively usually goes along with low investment in str...
13 C dynamics in benthic algae: Effects of light, phosphorus, and biomass development
13 C dynamics benthic algae light phosphorus biomass
2014/4/18
We performed three experiments in indoor streams and one experiment in a natural stream to investigate the effects of growth factors on d13 C levels in benthic microalgae. In the indoor streams, algae...
Colonization patterns of Nematoda on decomposing algae in the estuarine environment: Community assembly and genetic structure of the dominant species Pellioditis marina
Colonization patterns of Nematoda estuarine environment: Community assembly genetic structure dominant species Pellioditis marina
2014/4/22
We performed a field experiment in the Westerschelde Estuary (The Netherlands) to characterize the colonization dynamics of nematodes in relation to the proximity of a source population and to local e...
Importance of detrital algae, bacteria, and organic matter to littoral microcrustacean growth and reproduction
Importance of detrital algae bacteria organic matter
2014/4/22
Cumulative incorporation of radiolabeled algal (NaH14
CO3) and bacterial (14
C-acetate) carbon associated with
benthic organic matter (BOM) was measured at timed intervals to determine the relative...
Nitrogen incorporation and retention by bacteria, algae, and fauna in a subtropical intertidal sediment: An in situ 15N-labeling study
Nitrogen incorporation retention by bacteria
2014/4/22
We performed a 15N-labeling study to investigate nitrogen incorporation and retention by the benthic
microbial community (bacteria and benthic microalgae) and fauna in the intertidal sediment of the ...
Infochemical-mediated trophic interactions between the rotifer Brachionus calyciflorus and its food algae
Infochemical-mediated trophic interactions he rotifer Brachionus calyciflorus
2014/4/22
We studied how chemicals obtained as filtrates from algal monocultures (algal chemicals) and from rotifer
cultures with or without algae (rotifer chemicals) affected feeding rates of the rotifer Brac...
Benthic microbial and whole-community responses to different amounts of 13 C-enriched algae: In situ experiments in the deep Cretan Sea (Eastern Mediterranean)
Benthic microbial whole-community responses
2014/4/23
The deep eastern Mediterranean Sea is one of the most oligotrophic regions of the world’s oceans and is therefore
highly suitable for investigating the response of a resource-limited deep-sea benthic...
Mixotrophic versus photoautotrophic specialist algae as food for zooplankton: The light : nutrient hypothesis might not hold for mixotrophs
Mixotrophic versus photoautotrophic specialist algae food for zooplankton The light : nutrient hypothesis mixotrophs
2014/5/9
We reared mixotrophic (Ochromonas tuberculata and Cryptomonas sp.) and photoautotrophic specialist algae (Scenedesmus obliquus) at different light : phosphorus supplies and compared their effects as f...
Multiple scattering on coral skeletons enhances light absorption by symbiotic algae
Multiple scattering coral skeletons enhances light absorption symbiotic algae
2014/5/9
The success of symbiotic reef-building corals is largely determined by the efficiency with which they collect solar energy. Using thin coral laminae from the Caribbean scleractinian Porites branneri, ...
Phosphorus and trace metal limitation of algae and bacteria in Lake Superior
Phosphorus and trace metal algae and bacteria Lake Superior
2014/5/14
We performed a set of nutrient-enrichment bioassay experiments using metal-clean protocols, testing for macronutrient and micronutrient limitation of algae and bacteria in western Lake Superior. Our a...
Benthic algae control sediment–water column fluxes of organic and inorganic nitrogen compounds in a temperate lagoon
Benthic algae control sediment– water column fluxes organic and inorganic nitrogen compounds temperate lagoon
2014/5/22
Coastal lagoons are a common land-margin feature worldwide and function as an important filter for nutrients entering from the watershed. The shallow nature of lagoons leads to dominance by benthic au...
Greedy algae reduce arsenate
algae reduce arsenate
2014/5/22
Algae reduce and methylate arsenate, producing arsenite (As(III)) when the growth rates are high and dimethylarsinic acid (DMA) when the growth rates are low. In lakes, this leads to high As(III) conc...
