Phytoplankton in a temperate-zone salt marsh: Net production and exchanges with coastal waters

Long-term changes in temperate Australian coastal waters: implications for phytoplankton

A ~60 yr physical and chemical data set from 4 coastal stations around Australia plus remotely sensed SeaWiFS and phytoplankton taxonomic data were used to evaluate the temporal and spatial variation in phytoplankton ecology. The most consistent trend observed at all stations was a long-term increase in surface salinity of ~0.003 ± 0.0008 psu yr–1. All stations showed positive trends in tempera...

Temperature regulation of bacterial production, respiration, and growth efficiency in a temperate salt-marsh estuary

There is consensus that temperature plays a major role in shaping microbial activity, but there are still questions as to how temperature influences different aspects of bacterioplankton carbon metabolism under different environmental conditions. We examined the temperature dependence of bacterioplankton carbon metabolism, whether this temperature dependence changes at different temperatures, a...

Net ecosystem methane and carbon dioxide exchanges in a Lake Erie coastal marsh and a nearby cropland

Net ecosystem carbon dioxide (FCO2) and methane (FCH4) exchanges were measured by using the eddy covariance method to quantify the atmospheric carbon budget at a Typhaand Nymphaea-dominated freshwater marsh (March 2011 to March 2013) and a soybean cropland (May 2011 to May 2012) in northwestern Ohio, USA. Two year average annual FCH4 (49.7 g C-CH4 m 2 yr ) from themarsh was high and compatible ...

Assessment of methylmercury production in a temperate salt marsh (Ria de Aveiro Lagoon, Portugal).

Study of phytoplankton community in coastal waters of Hormozgan province, Qeshm and Leangeh Islands

The study of spatial and temporal variability of distribution of phytoplankton communities in Northern part of the Persian Gulf (Qeshm andLengeh Islands) was studied. In this study, five groups (47 genera) of phytoplankton include Bacillariophyceae, Dinophyceae, Cyanophyceae, Crysophyceae and Euglenophyceae were identified. The results showed that Diatoms group (79.6 %) and Rhizosolenia genus (...
