Microbiology of Seamounts:Common Patterns Observed in Community Structure
Microbiology of Seamounts Common Patterns Observed Community Structure
2015/7/7
Much interest has been generated by the discoveries of biodiversity associated with seamounts. The volcanically active portion of these undersea mountains hosts a remarkably diverse range of unusual m...
Seasonal and interannual change in a Chesapeake Bay eelgrass community: Insights into biotic and abiotic control of community structure
Seasonal and interannual change Chesapeake Bay eelgrass community Insights into biotic abiotic control of community structure
2014/4/17
We characterized the seasonal and interannual variation in macrophytes, epiphytes, invertebrate herbivores, small demersal predators, and physicochemical characteristics of an eelgrass (Zostera marina...
Seasonal analysis of protistan community structure and diversity at the USC Microbial Observatory (San Pedro Channel, North Pacific Ocean)
protistan community structure USC Microbial Observatory
2014/4/17
The structure and genetic diversity of marine protistan assemblages were investigated in the upper 500 m of the
water column at a Pacific Ocean time-series station off the coast of Southern Californi...
Community Structure Dynamics of the Hermatypic Corals on Luhuitou Fringing Reef, Hainan, China. I. Species Composition and Abundance
Luhuitou fringing reef hermatypic corals community structure
2009/9/23
The existing hermatypic coral community is composed of localities in different successional ages．
Data sets were selected from original sampling data to deduce the trajectory of community structure i...
Contrasting the influences of stream inputs and landscape position on bacterioplankton community structure and dissolved organic matter composition in high-elevation lake chains
Contrasting landscape position
2014/4/18
We examined bacterioplankton community composition (BCC; using polymerase chain reaction-based
phylogenetic fingerprinting) and the composition of dissolved organic matter (DOM; using scanning fluoro...
Benthic community structure and spatiotemporal thermal regimes in two upwelling ecosystems: Comparisons between South Africa and Chile
Benthic community structure spatiotemporal thermal regimes
2014/4/18
On the basis of 16-yr satellite time series (1987–2003) of sea surface temperature (SST) and using univariate and
multivariate statistical techniques, we quantified patterns of fluctuation in oceanog...
Relating phytoplankton photophysiological properties to community structure on large scales
phytoplankton photophysiological properties community structure large scales
2014/4/21
We analyzed a large dataset of simultaneous measurements of phytoplankton pigments, spectral specific absorption coefficient for phytoplankton [a*(l)], and photosynthesis versus irradiance (P versus E...
Molecular analysis of picocyanobacterial community structure along an Arabian Sea transect reveals distinct spatial separation of lineages
picocyanobacterial community structure lineages
2014/5/5
We investigated the community structure of Synechococcus and Prochlorococcus along a transect in the
Arabian Sea during September 2001. The transect spanned contrasting oceanic conditions, allowing i...
Molecular analysis of photosynthetic picoeukaryote community structure along an Arabian Sea transect
Molecular Arabian Sea transect
2014/5/5
We developed oligonucleotide probes, based on plastid 16S ribosomal DNA (rDNA) sequences, to target 10
different algal classes (Chlorarachniophyceae, Chrysophyceae, Cryptophyceae, Eustigmatophyceae, ...
Biomarker and carbon isotopic constraints on bacterial and algal community structure and functioning in a turbid, tidal estuary
Biomarker carbon isotopic constraints bacterial and algal community structure functioning tidal estuary
2014/5/8
We studied planktonic community structure and isotopic composition using compound-specific 13C analysis of phospholipid-derived fatty acids (PLFA) along the Scheldt estuary during a spring bloom. A co...
Dynamics of community structure and phosphate status of picocyanobacterial populations in the Gulf of Aqaba, Red Sea
community structure phosphate status picocyanobacteria populations Gulf of Aqaba Red Sea
2014/5/8
We monitored the genetic diversity and phosphate (P) status of Prochlorococcus and Synechococcus populations during an annual cycle (1999-2000) in the Gulf of Aqaba, Red Sea, using DNA probes and anti...
