microscopic algae eaters called rotifers being grown for the DISCOVR project.
TDA is produced by marine bacteria belonging to the roseobacter family, which exist in a unique symbiosis
with microscopic algae.
On Earth, masses of
microscopic algae form large, layered structures known as stromato - lites, which survive as fossils on lake beds, and the putative Martian algae might have done the same thing, said Jack Farmer, one of McKay's colleagues.
The herbicide also led to more food for the snails, because it predominately
killed microscopic algae that clouded the water.

certain microscopic algae — that is, types of phytoplankton — cause harm to fish, shellfish, marine mammals, seabirds, and people?
By dating the cores and
examining microscopic algae known as diatoms, the research team was able to piece together a history of the lakes» ecology.
As nutrients remain stuck at the bottom of the lake, organisms ranging
from microscopic algae to fish can be threatened.
The first took place from June to August 2011, when large numbers of diatoms (a type
of microscopic alga) bloomed near the surface, then sank rapidly to the seafloor.
Bleaching occurs when corals expel
the microscopic algae that normally live inside their hard skeletons, providing them with food and their bright coloration.
He studied remains of two organisms —
a microscopic algae and the waxy coating of mangrove leaves — for clues to the amount of past rainfall.
Algae can also be used for biomanufacturing:
Microscopic algae are turned into a living machine that can be genetically programmed to produce molecules like lipids and hydrocarbons ideally suited for biofuels.
For the ocean's tiny grazing animals,
the microscopic algae called diatoms are a favorite food — and like most delicacies, they are turning out to be hazardous.
Heat merely caused them to expel the colored,
microscopic algae that live inside them and provide food.
Over the oceans, some contain organic or biological ingredients (bacteria, degradation products of
microscopic algae) which come from sea spray, others are transported in the air (mineral dust, smoke).
One beneficiary of this young researcher exchange program was Matthew Julius, who studies the evolution of diatoms, a group of
microscopic algae, now at St. Cloud State University in Minnesota.
Pseudo-nitzschia is
a microscopic algae that occurs naturally in coastal waters, and is of particular concern due to its production of the neurotoxin domoic acid.
This water often carries nutrients that
microscopic algae (phytoplankton) need to survive.
As the LRAUVs move through the ocean, they collect information about water temperature, chemistry, and chlorophyll (an indicator of
microscopic algae) and send this data to scientists on shore or on a nearby ship.
