Photophysiological responses of bottom sea-ice algae to fjord dynamics and rapid freshening

Frontiers in Marine Science, 2023
Sea ice algae have a broad salinity tolerance but can experience stress during rapid decreases in salinity that occur with seasonal ice melt and during ice sample melt. This study investigated the impact of salinity on the photophysiological responses of

Urbanization Alters the Influence of Weather and an Index of Forest Productivity on Avian Community Richness and Guild Abundance in the Seattle Metropolitan Area

Frontiers in Ecology and Evolution, 2017
Fluctuations in weather and forest productivity influence the abundance and richness of bird populations, however in a rapidly urbanizing landscape the relative importance of each factor may vary.

Coccolith counting and reconstructed primary productivity results of core MD00-2354

, 2022
Coccolith assemblages of core MD00-2354 are used for reconstructing primary productivity in the northwestern Arabian Sea. The results cover the last 23,000 years.

Rapid primary productivity changes in one of the last coastal rainforests : the case of Kahua, Solomon Islands [PDF]

, 2009
The growth of human populations has many direct and indirect impacts on tropical forest ecosystems both locally and globally. This is particularly true in the Solon-ion Islands, where coastal rainforest cover still remains, but where climate change and a

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]

, 2010
Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.

Primary productivity of phytoplankton estimated with the oxygen and carbon fourteen methods at one station of Estero de Punta Banda, Mexico

Ciencias Marinas, 1997
 In order to estimate primary productivity of the phytoplankton using the dissolved oxygen (ΔO2) method with different incubation times and to compare it with that estimated using the carbon fourteen (14C) method, simultaneous primary productivity ...

Iron Regulation of North Atlantic Eddy Phytoplankton Productivity

Geophysical Research Letters, 2021
Cyclonic ocean eddies drive upwelling of deep waters enhanced in nutrients, which can elevate phytoplankton productivity. At mid‐latitudes in the North Atlantic, satellite images show enhanced chlorophyll‐a associated with eddies.

Synthesizing Empirical and Modelling Studies to Predict Past and Future Primary Production in the North Sea

Frontiers in Marine Science, 2022
Understanding change at the base of the marine foodwebs is fundamental to understanding how climate change can impact fisheries. However, there is a shortage of empirical measurements of primary productivity, and models estimates often disagree with each
