Water residence time is the factor that most affected the abundance of zooplanktonic organisms. |
|
Fishless lakes had a greater abundance of zooplanktonic organisms and a greater diversity of amphibians than lakes with fish. |
|
This cnidarian captures zooplanktonic organisms by injecting a toxin that paralyzes them. |
|
When used in line with the CUFES it provided high resolution maps of staged fish eggs and zooplanktonic functional groups. |
|
Protoodinium, Crepidoodinium, Piscinoodinium, and Blastodinium retain their plastids while feeding on their zooplanktonic or fish hosts. |
|
Hence the ZooCAM is an appropriate tool for the development of on board, high frequency, high spatial coverage zooplanktonic and ecosystemic studies. |
|
A comparison with the ZooScan, on a more complex zooplanktonic community, provided encouraging results on the agreement between the 2 instruments. |
|
Most zooplanktonic organisms make daily vertical migrations between the surface water layer, where they feed at night, and the deeper waters, where they can be safe from predators during the day. |
|
Zooplanktonic biomass showed the same pattern of change as phytoplanktonic biomass, with a lag of about a year. |
|
Zooplanktonic biomass fell somewhat due to the shorter water residence time. |
|
Zooplanktonic organisms feed on algae, and all juvenile fish feed on zooplankton, at least as fry or as very young fish. |
|
Zooplanktonic and benthic densities and biomasses are the same as before the diversion. |
