Integrated Carbon Budget Models for the Everglades Terrestrial-Coastal-Oceanic Gradient: Current Status and Needs for Inter-Site Comparisons
Terrestrial-Coastal-Oceanic Gradient Inter-Site Comparisons
2015/7/16
Recent studies suggest that coastal ecosystems can bury significantly more C than tropical forests, indicating that continued coastal development and exposure to sea level rise and storms will have gl...
Phosphorus loading of mountain lakes: Terrestrial export and atmospheric deposition
Phosphorus loading mountain lakes Terrestrial export atmospheric deposition
2014/4/8
We studied the atmospheric deposition of phosphorus (P) forms along an elevation gradient, and its contribution to the total external P loading of lakes in the Tatra Mountains and the Bohemian Forest,...
Terrestrial organic matter and light penetration: Effects on bacterial and primary production in lakes
Terrestrial organic matter light penetration on bacterial primary production in lakes
2014/4/17
We investigated productivity at the basal trophic level in 15 unproductive lakes in a gradient ranging from clear-water to brown-water (humic) lakes in northern Sweden. Primary production and bacteria...
Regulation of the nitrogen biogeochemistry of mountain lakes by subsidies of terrestrial dissolved organic matter and the implications for climate studies
the nitrogen biogeochemistry mountain lakes subsidies terrestrial dissolved organic matter the implications for climate
2014/4/16
table isotopes of nitrogen (N) were analyzed in modern sediments of mountain lakes, dissolved organic matter(DOM), and sediment cores spanning the past 12,000 yr to test the hypothesis that spatial an...
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...
Sources and transport of terrestrial organic matter in Vancouver Island fjords and the Vancouver–Washington Margin: A multiproxy approach usingd13Corg, lignin phenols, and the ether lipid BIT index
terrestrial organic matter Vancouver Island fjords the Vancouver–Washington Margin multi proxy approach d13 Corg lignin phenols ether lipid BIT index
2014/4/21
The Branched and Isoprenoid Tetraether (BIT) index (a ratio of marine and terrestrial glycerol dialkyl glycerol tetraether [GDGT] membrane lipids) was recently introduced as a proxy for the fraction o...

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...
Effects of salinity changes on the photodegradation and ultraviolet–visible absorbance of terrestrial dissolved organic matter
salinity changes photodegradation ultraviolet– visible absorbance terrestrial dissolved organic matter
2014/5/5
We performed laboratory studies to determine the effects of salinity on the photodegradation of dissolved organic matter (DOM) from the Great Dismal Swamp, Virginia, an important source of terrestrial...
Characterization of transport and deposition of terrestrial organic matter in the southern North Sea using the BIT index
transport and deposition terrestrial organic matter southern North Sea BIT index
2014/5/5
We have applied a recently introduced proxy, the BIT (branched and isoprenoid tetraether) index, to determine terrestrial organic matter (TOM) transport from the rivers Rhine and Meuse and their tribu...
Can feeding of fish on terrestrial insects subsidize the nutrient pool of lakes?
errestrial insects subsidize lakes
2014/5/13
We estimated consumption and excretion rates of terrestrial-borne phosphorus by a population of the insectfeeding fish species bleak (Alburnus alburnus) in a 0.12-km2
mesotrophic lake of the Ge...
Stable carbon and nitrogen isotope composition of aquatic and terrestrial plants of the San Francisco Bay estuarine system
Stable carbon nitrogen isotope composition aquatic and terrestrial plants San Francisco Bay estuarine system
2014/5/27
We report measurements of seasonal variability in the C-N stable isotope ratios of plants collected across the habitat mosaic of San Francisco Bay, its marshes, and its tributary river system. Analyse...
