Project "The World Water Day 2019 - BioBlitz March 22 to 24"

"World Water Day is an annual UN observance day (always on 22 March) that highlights the importance of freshwater. The day is used to advocate for the sustainable management of freshwater resources. World Water Day is celebrated around the world with a variety of events. These can be educational, theatrical, musical or lobbying in nature." [1]
It is well known that the forms of live we deal with in the earth are all, or nearly all, dependent of the water. Being so, we needed to choose some few to catalog in the World Water Day. We avoided the obvious species that expend all their lives in the water (fishes, algae, for exemple), in favor of some that have have relation to water either in time or space, are around us, and do not demand sophisticated equipments to observe them.
"Amphibians are small vertebrates that need water, or a moist environment, to survive.
The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin." [2]
"Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water." [3]
"Bromeliads often serve as phytotelmata, accumulating water between their leaves. The aquatic habitat created as a result is host to a diverse array of invertebrates, especially aquatic insect larvae. These bromeliad invertebrates benefit their hosts by increasing nitrogen uptake into the plant. [4]
"Nymphaeales, the water lily order of flowering plants, is found in quiet freshwater habitats throughout most of the world.
All plants of the Nymphaeales order are aquatic." [5]
The results show that, for the categories of life being observed by the Project, 62% were observations of Amphibians, while 34% were of Cactuses, only 3% of Bomeliads, and even fewer, only 1% of Nymphaeales.
The result for Nymphaeales did not surprise me, but the result for Amphibians was quite impressive since I hardly observe one.
