Human exploration of space and other celestial bodies bears a multitude of challenges. The
Earth-bound supply of material and food is restricted, and in situ resource utilisation (ISRU) …

Motile microorganisms utilize a number of responses to external stimuli including light,
temperature, chemicals as well as magnetic and electric fields. Gravity is a major clue to …

Photosynthetic microalgae have a high potential for the production of biofuels and highly
valued metabolites. However, their current industrial exploitation is limited by a productivity …

The effects of ultraviolet B (UV-B; 295–320nm) radiation on certain vital physiological
(photosynthesis), biochemical (production of reactive oxygen species–ROS) and behavioral …

Photosynthesis produces chemical energy from photon energy in the photosynthetic
electron transport and assimilates CO2 using the chemical energy. Thus, CO2 limitation …

Gonyostomum semen experiences a remarkable expansion in parts of Europe, partially
driven by rising levels of dissolved organic matter (DOM), also called lake browning. One …

We observed diurnal vertical migrations (DVMs) of four noxious phytoflagellates: Chattonella
antiqua, Heterosigma akashiwo (raphidophyte), Karenia mikimotoi, and Heterocapsa …

A rapid, sensitive algal bioassay was investigated to monitor copper toxicity using
photosynthetic activity and motility parameters as end points in the photosynthetic flagellate …

We examined the effects of salinity on diel vertical migration (DVM) of two coastal flagellates,
Chattonella antiqua and Karenia mikimotoi, in 90-cm-high columnar aquariums …

The unicellular freshwater flagellate Euglena gracilis regulates its position in the water
column by means of phototactic and gravitactic behavior. Recent experiments have revealed …
