Benthic algal response to N and P enrichment along a pH gradient

Structure of Benthic Communities along the Taiwan Latitudinal Gradient

The distribution and the structure of benthic assemblages vary with latitude. However, few studies have described benthic communities along large latitudinal gradients, and patterns of variation are not fully understood. Taiwan, lying between 21.90°N and 25.30°N, is located at the center of the Philippine-Japan arc and lies at the northern margin of coral reef development. A wide range of habit...

Strong gradient of benthic biogeochemical processes along a macrotidal temperate estuary: focus on P and Si cycles

Strong gradient of benthic biogeochemical processes along a macrotidal 1 temperate estuary : focus on P and Si cycles 2 3

12 13 This study aims to investigate the role of spatial and temporal physical, biological and 14 biogeochemical gradients on sediment biogeochemistry along a macrotidal and Si-rich estuary. 15 Scanning and biogeochemical analyses were performed in the inner, mid and outer Aulne Estuary 16 (France) at four seasons. The inner estuary shows high diagenetic activity linked to fluid mud 17 dynamics...

A model of river benthic algal photosynthesis in response to rapid changes in light’

A linear relationship has been found between light and community productivity in a river, but the correlation is reduced when radiation varies rapidly due to the passage of cumulus clouds. To investigate the relationship during periods of patchy cloudiness we developed a method of calculating short term variations in oxygen exchange based on oxygen measurements taken at very frequent intervals....
