]]>There are an estimated 8.7 million eukaryotic species on the planet. These are organisms whose cells contain a nucleus and other membrane-bound organelles. Although eukaryotes include the familiar animals and plants, these only represent two of the more than six major groups of eukaryotes.
The bulk of eukaryotic diversity comprises single-cell eukaryotic microorganisms, known as protists. By studying protists, scientists can gain insight to the evolutionary processes that shaped the diversity and complexity of eukaryotic life and led to innovations such as multicellularity that made animal life on the planet possible.
As researchers work toward a better understanding of the mechanisms behind the evolution of species on Earth, questions remain about how microbial eukaryotes adapted to the planet's extreme environments. To dive further into this topic, scientists in the College of Arts and Sciences' (A&S') Department of Biology are currently investigating protists that inhabit some of the harshest environments on Earth: extremely hot and acidic geothermal lakes.
A team led by Angela Oliverio, assistant professor of biology, recently returned from Lassen Volcanic National Park in California, home to the largest geothermal lake in the U.S.
"This lake is an acid-sulfate steam-heated geothermal feature, meaning it is both quite hot (~52C/124F) and acidic (pH ~2)," says Oliverio, who started at Syracuse University in 2022. "This makes it a very unique environment to study polyextremophiles, which are organisms that have adapted to two or more extreme conditions - in this case high temperature and low pH."
So how did they know to travel to a hot lake in California to find microbial eukaryotic life? In a recent study published in Nature Communications co-authored by Oliverio and Hannah Rappaport, a researcher in Oliverio's lab, the team built a database of previous studies that searched for microbial eukaryotic life across extreme environments. Specifically, they analyzed which eukaryotic lineages were detected multiple times from different studies under similar environmental conditions.
"We discovered that several lineages of amoebae were often recovered from extremely high temperature environments," says Oliverio. "This suggests that studying those lineages may yield great insight into how eukaryotic cells can adapt to life in extremely hot environments."
According to Oliverio, one particular study conducted by Gordon Wolfe's lab at Cal State Chico revealed an amoeba, T. thermoacidophilus, was quite abundant in Lassen National Park's geothermal lake. However, no genomic data on this organism exists. Determining how this species adapted to this extreme environment could expand the understanding of what types of environments in the Universe may be considered suitable for life.

The Cryovolcano or Ice-Volcano one process hypothesized to be a significant source of the methane found in Titan's atmosphere the process of cryovolcanism a type of offworld volcano that erupts volatiles such as water, ammonia or methane, perhaps also a process happening on Pluto. Cassini photographed geysers on the south pole of Enceladus, evidence of cryovolcanic activity was later observed on several other icy moons of the Solar System, including Europa, Ganymede, and Miranda, two distinct bright spots inside a crater of the dwarf planet Ceres were imaged by the Dawn spacecraft. Our Moon has less sign of Volcanoes, the lunar lava, volcanic mountains were seldom created, it does have events which are interpreted as pyroclastic deposits. Venus, there is geological activity, the volcanic features are very numerous and quite diverse, but, like on Mars, none are known to be currently active. Mercury perhaps had volcanoes and Mercury's basins are smooth plains, like the lunar mare, that are believed likely to be filled with past lava flows

Juno Reveals Volcanoes on Io
https://www.universetoday.com/161391/ju … oes-on-io/
Jupiter’s moon Io is the most volcanic world in the Solar System, with over 400 volcanoes. Some of them eject plumes as high as 500 km (300 mi) above the surface. Its surface is almost entirely shaped by all this volcanic activity, with large regions covered by silicates, sulphur, and sulphur dioxide brought up from the moon’s interior. The intense volcanic activity has created over 100 mountains, and some of them are taller than Mt. Everest.
Io is unique in the Solar System, and the Juno orbiter’s JunoCam captured some new images of Io’s abundant volcanic activity.
Io is in a tough position. It’s locked in a kind of gravitational tug-of-war with massive Jupiter and the other Galilean moons, Ganymede, Europe, and Callisto. All that gravitational energy, particularly from Jupiter and Europa, creates friction in the moon’s interior that creates ‘tidal heating.’ That sets it apart from Earth’s volcanism, which is caused largely by the heat from the decay of radioactive isotopes in the mantle, including uranium, potassium, and thorium. In fact, Io produces bout 40% more heat than Earth, an amount that simply cannot be produced by radioactive decay.
