Hey All. I just crossed a contradictory line when regarding to water issues on delay of metamorphosis.
I am having a problem with some of my larvae witch are incredibly morphing at super small sized animals Thing is that the info I have is:
Factors that promote metamorphosis:
-->Shallow waters
--> T > ~20ºC
--> [O2] < 1,24 x10^-3 mol^ L-1
Factors that delay metamorphosis OR promote neoteny:
--> Deep waters
--> T< ~20ºC
--> [O2] > 1,24 x10^-3 mol^ L-1
Thing is that this all is serious interrelated:
Oxygen concentration is bigger in shallow waters;
Oxygen solubility in water is as big as lower the temperature is.
So if we have a shallow, hot water pond vs a deep cool pond, witch one will promote neoteny/ delay on metamorphosis?! Remember that the deeper the pond the lower the [O2]. And in shallow waters, despite bigger temps, [O2] is bigger too, witch is a complete mess. I am starting to get really confused. As far as i can see in the end the real factor that triggers both morphing or neoteny is [O2] in water...? No matter the other factors?
:errr:
thanks,
Jorge
