Zooplankton are important to ensuring the lake’s clarity because they eat the particles that cloud the lake. Lake Tahoe made a comeback in 2022, with its average annual clarity reaching 71.7 feet.

Daphnia and Bosmina zooplankton are shown in an illustration provided by researchers at UC Davis’ Tahoe Environmental Research Center. On Monday, the center announced that clarity in the lake ...

Scientists say the lake is clearest when the zooplankton Daphnia and Bosmina, which had once almost vanished, are most abundant. “Biologically, things are changing,” said Schladow.

Some zooplankton, particularly Daphnia and Bosmina, are specialized to consume particles in that critical size range. “Daphnia and Bosmina largely disappeared from the lake after they were grazed down ...

How do zooplankton change a lake's clarity? Zooplankton — which began to decline in the 1960s due to the growth of its primary predator, the Mysis shrimp — can help improve the lake’s ...

Zooplankton, especially the Daphnia and Bosmina species, have dropped to dangerously low levels over the years, hitting a record low in 2021.

The native zooplankton are small, microscopic animals. Since the 1960s, the zooplankton populations have decreased due to the growth of its primary predator, the Mysis shrimp. Zooplankton, especially ...
