#043 - Zestdrop

Living high among the clouds, these microscopic creatures rain from above after a life of energetic swimming! At some point, they are filled with too much Zest for Life for their small bodies, so they must fall to share it with the creatures below!

If you're out under the rain and one of them falls on you, you'll be overcome with a love for being alive!!!

After disposing of their excess energy, they hitch rides on Evaporise to get back in the clouds and swim happily for more days to come!

Inspired by water fleas and having fun under the rain!

RISING CARBON DIOXIDE LEVELS ARE ACIDIFYING FRESHWATER ECOSYSTEMS TOO

As ocean acidification, the excess of CO2 emitted into the atmosphere is having a bad effect on freshwater ecosystems, according to a study published in Current Biology.

According to researchers, some freshwater ecosystems have become more acidic with the increase in pCO2 (partial pressure of CO2) and, in laboratory studies, the increases of pCO2 freshwater can have detrimental effects on at least one key species, specifically water flea, a small freshwater crustacean, leaving it less able to detect and defend against predators. The findings suggest that the increase in CO2 levels may be having widespread effects on freshwater ecosystems.

Using monitoring data for 30 years, scientists report a change in pH of around 0.3 in 35 years, suggesting that freshwater can be acidified at a faster rate than the oceans.

ZOOPLANKTON FAUNA OF A SECTION OF OGBESE RIVER, EKITI STATE, NIGERIA |  Journal of Global Agriculture and Ecology

The number and variety of zooplankton in a segment of the Ogbese River in Ado Ekiti were studied in this study. For a period of three months, samples were taken every two weeks. A total of 16 zooplankton genera from three families were discovered. Rotifera, Cladocera, and Copepod were the zooplankton groups found. The largest relative abundance of individuals was seen in Rotifera (61.7 percent ). Copepoda (24.7 percent) and Cladocera came in second and third, respectively (13. 4 percent ). Rotifera has 343 individuals per ml of water sample, Copepoda has 137 individuals per ml, and Cladocera has 74 individuals per ml of water sample, according to the numerical abundance. Rotifera > Copepoda > Cladocera is the order of zooplankton abundance. Please see the link :- https://www.ikprress.org/index.php/JOGAE/article/view/254
