seasonality Amazon evergreen forests
2016/3/2
Sometimes you can't see the forest for the trees. In the Amazon, the opposite is true: without truly seeing the trees, you can't "see" the forest and understand the seasonal patterns of photosynthesis...
Most descriptions of sounds produced by whales at sea have been described from scattered, unsystematic observation and recording of animals during shipboard encounters. Such encounters provide data on...

The Japan/East Sea (JES) contains several oceanic regions separated by dynamic boundaries. These distinct regions, and the physical features that establish and maintain the boundaries between the regi...
Solid phase phosphorus species and preservation of fish remains in marine sediments of areas of high primary productivity and oxygen seasonality (36°S, central South Chile)
fish debris biogenic apatite seasonal coastal upwelling hypoxia central-south Chile
2017/4/10
The main input of phosphorus to the ocean is associated with river runoff, while this element leaves the marine system
via burial in the sediments. Solid phase P accumulation is a function of bottom ...
