Species and δ15N Signatures of Nitrogen Transformations in the Suboxic Zone of the Black Sea
Species and δ15N Signatures Nitrogen Transformations Suboxic Zone of the Black Sea
2015/7/27
Nitrogen is an essential nutrient for living systems in the ocean; it is a component of proteins, chlorophyll, and nucleic acids. In the oceans, nitrogen exists as a dissolved gas (N2), dissolved orga...
Population Connectivity and Larval Dispersal Using Geochemical Signatures in Calcified Structures
Population Connectivity Larval Dispersal Geochemical Signatures Calcified Structures
2015/7/22
The importance of larval dispersal to the population dynamics and biogeography of marine organisms has been recognized for almost a century (Hjort, 1914; Thorson, 1950). More recently, theoretical stu...
Microevolution in time and space: SNP analysis of historical DNA reveals dynamic signatures of selection in Atlantic cod
fi sheries-induced evolution Gadus morhua genome scan
2015/12/11
Little is known about how quickly natural populations adapt to changes in their environment and how temporal and spatial variation in selection pressures interact to shape
patterns of genetic diversi...
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures of a lake food web
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/4
Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...

2014/4/17
A pattern of succession has been demonstrated at Gulf of Mexico cold seeps proceeding from a high-biomass
endemic community dominated by grazers to a diverse community of endemic and nonendemic speci...
Signatures of Mixing from the Bermuda Slope, the Sargasso Sea and the Gulf Stream
Mixing Sargasso Sea Bermuda Slope Gulf Stream
2009/2/16
Nearly simultaneous profiles of temperature microstructure and velocity shear were made adjacent to the island of Bermuda. Profiles with elevated microstructure levels were found in close association ...
Tidal Mixing Signatures in the Indonesian Seas
Tidal Mixing Signatures low-frequency tidal Indonesian Seas
2008/12/10
Expressions of low-frequency tidal periods are found throughout the Indonesian Seas' temperature field, supporting the hypothesis that vertical mixing is enhanced within the Indonesian Seas by the tid...
Tracing terrestrial organic matter by d34S and d13C signatures in a subarctic estuary
Tracing terrestrial organic matter d34S and d13C signatures a subarctic estuary
2014/4/21
A key issue to understanding the transformations of terrestrial organic carbon in the ocean is to disentangle the latter from marine-produced organic matter. We applied a multiple stable isotope appro...

Nitrogen and oxygen isotopic signatures of subsurface nitrate seaward of the Florida Keys reef tract
Nitrogen oxygen isotopic signatures subsurface nitrate seaward Florida Keys reef tract
2014/4/22
Hydrographic and nutrient structure and the nitrogen and oxygen isotopic compositions (d15N and d18O) of the nitrate pool seaward of the Florida Keys reef tract were measured in Summer 2003. Nitrate a...

Stable isotope signatures of benthic invertebrates in arctic lakes indicate limited coupling to pelagic production
Stable isotope signatures benthic invertebrates
2014/4/23
We tested the hypotheses that benthic macroinvertebrates, especially chironomid larvae in the Tribe Chironomini,
from small oligotrophic arctic lakes are only weakly linked to pelagic food sources, a...
