These first lines of Hensen’s article (Figure 1) in the “Fünfter Bericht” (1887) translate as follows [...]

Over the millennia, phytoplankton have evolved adaptations to reduce sinking rates and increase amount of time they are able stay in photic zone; one such adaptation is increasing form resistance with larger surface areas. Spines, flattened body shape, forming chains, so forth can area slow rates. While there many plankton rate activities accessible on web, this middle high school level laborat...

In aquatic ecosystems, primary production (the transformation of inorganic materials and light into living matter by photosynthesis) is operated mainly by small, unicellular algae that float freely in the upper layers of oceans and lakes and are collectively called phytoplankton, see for an illustration the phytoplankters depicted in figure 1. Since phytoplankton need light, they are confined t...

Efforts this year focused on testing our model of the effects of episodic increases in current shear on the dynamics and impacts of thin layers of phytoplankton and zooplankton. Thin layers are plankton patches that range in thickness from a few tens of centimeters to a few meters, yet can be sufficiently intense to affect biological rate processes and the performance of current and planned Nav...
