Movement Patterns of Brook Trout in a Restored Coastal Stream System in Southern Massachusetts
acoustic telemetry migration fish ecology
2014/11/5
Populations of anadromous brook trout can be found from northern Canada into New England. It is believed that the extent of anadromy exhibited by coastal brook trout populations decreases with latitud...

Hydrogen peroxide dynamics in an agricultural headwater stream: Evidence for significant nonphotochemical production
Hydrogen peroxide dynamics nonphotochemical production
2014/4/2
Hydrogen peroxide (H2O2
) plays key roles in aquatic systems, including metal redox cycling and degradation
of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...

Ghost cat cat puma tupi predators habitat
2015/7/7
The ghost cat, it's been called, this feline that roams backcountry from the Yukon to Chile. It has dozens of names, from panther, to puma, to mountain lion. But its best descriptor, perhaps, is couga...
Meiofauna versus macrofauna: Secondary production of invertebrates in alowland chalk stream
Meiofauna macrofauna Secondary production invertebrates in alow chalk stream
2014/4/17
The whole metazoan community inhabiting macrophyte stands and gravel beds of the English chalk stream River Lambourn were sampled for 1 yr. Secondary production estimates for specific taxa of macrofau...
Nutrient enrichment differentially affects body sizes of primary consumers and predators in a detritus-based stream
Nutrient enrichment differentially affects body sizes predators
2014/4/17
We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...
Unraveling the role of land use and microbial activity in shaping dissolved organic matter characteristics in stream ecosystems
role of land use microbial activity in shaping dissolved organic matter in stream ecosystems
2014/4/17
Surface water samples were collected from 43 streams distributed throughout watersheds of mixed land use in southern Ontario, Canada. Absorbance and fluorescence spectroscopy with parallel factor anal...
Surface flow structure of the Gulf Stream from composite imagery and satellite-tracked drifters
Surface flow structure Gulf Stream composite imagery satellite-tracked drifters
2009/11/16
A unique set of coutemporaneous satellite-tracked drifters and five-day composite Advanced Very High Resolution Radionmeter (AVHRR) satellite imagery of the North Atlantic has been analyzed to examine...
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...
Upstream resource abundance determines the food searching behavior of a stream grazer: Effect of microalgal cues
Upstream resource abundance determines searching behavior
2014/4/18
To maximize their growth, grazers should shift their behavior to balance the cues from predators and
periphyton in the field. As a stream grazer seeks periphyton that are heterogeneously distributed,...
Temporal dynamics of seston: A recurring nighttime peak and seasonal shifts in composition in a stream ecosystem
A recurring nighttime peak seasonal shifts
2014/4/17
We measured the baseflow concentration and composition of seston and suspended particulate organic carbon
(POC) over a 1-yr period in White Clay Creek, a third-order stream in the southeastern Pennsy...
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 ...
The influence of in-stream structures on summer water temperatures via induced hyporheic exchange
in-stream structures summer water temperatures
2014/4/17
Temperature is an important controlling factor for ecological functions. In-stream geomorphic structures
affect stream thermal regimes by facilitating hyporheic exchange of water and heat between str...
The Alaskan Stream boundary current south of the uniformly curving coastline formed by the Alaskan peninsula-Aleutian Island chain is examined analytically via steady, barotropic frictional theory. It...
The Structure of the Residual Flow in an Offshore Tidal Stream
Residual Flow an Offshore Tidal Stream
2009/4/3
A theoretical account is given of the turbulent boundary layer at the ocean floor beneath a co-oscillating tidal flow. A parameterization, involving the techniques described by Johns and Dyke, is used...
