CUBE ChatShaala: 4th Dec 20
This slide is selfexplanatory. Isn’t it?
CUBists from The Cochin College, Ernakulam, Kerala have joined in the CUBE Mango Phenology 2020 studies.
Utilising their reach, data was collected from as many as four districts of Kerala namely Malappuram, Ernakulam, Alappuzha and Kollam (their respective latitudes have been mentioned in the slide).
Kollam is the southernmost district (out of the four) and Malappuram is the northernmost.
Aarcha was interpreting their study so far and built a hypothesis alongwith everyone so that we could find out whether the observations that are being made in these four districts go alongside the hypothesis or disprove it?
According to the hypothesis, flowering of mango trees starts first in the south (lower latitudes) and then gradually moves north (upper latitudes).
This hypothesis is based on the data that was collected till the last week of November from States/UTs such as Kerala (Thrissur, Kozhikode, Ernakulam, Malappuram, Kollam, Alappuzha districts), Pondicherry, Goa, Maharashtra (Ratnagiri, Mumbai Region, Latur), Jharkhand (Ranchi region), Bihar (Patna, Sitamarhi), West Bengal (Kolkata), Assam (Silchar, Sonari), Uttar Pradesh (Moradabad), Rajasthan (Jaipur) and Delhi.
Flowering has started and is being observed in trees till Maharashtra (Mumbai Region being the topmost latitude) and above 19’N (latitude of Mumbai), no flowering is seen in other states.
It is speculated that mango trees will start flowering anytime soon in the areas where it isn’t flowering.
Isn’t it a good time to capture this phenomenon of the flowering of Mango trees live across all centres/places/locations?
Using the reach of the CUBE Community, capturing this isn’t a herculean task!
As the discussed progressed, we figured out that from 8’N (southernmost latitude of India) till 34’N (Srinagar, JK), CUBists are dispersed everywhere!
We all can experience it and contribute to this by mapping the trees nearby and not only we ourselves but sharing this with our friends, family and relatives will inculcate their curious minds as well so that they will develop an interest in knowing the process.
It is like an actual lab-based experiment where we develop a hypothesis and test it by doing experiments/assays and here, the Mango trees are what we are keen upon! Observations need to be made and then interpretation and reporting of it will be done collaboratively so that everyone gets an insight.
Capturing the trees atleast in the state-capitals (MH: Mumbai, Kerala: Trivandrum, WB: Kolkata, JH: Ranchi, Delhi and so on) will be a good start!
We need not go outside ourselves, but popularising this will help!
Further, the discussion reached on an interesting observation in the Navi Mumbai region of Maharashtra that was made in the first week of December.
@Shraddha CUBE HBCSE Cardamine from Panvel, NM (18.98’N) shared that ~70 Mango trees had been surveyed by her and none of them were flowering (i.e. 0%flowering!)!
At a similar latitude in South Mumbai (Breach Candy 18.97’N), @Arunan HBSCE had observed that Mango trees have started flowering there (percentage w.r.t. sample size needed)!
I myself had surveyed 32 trees in Nerul, Seawoods (19.04’N) in NM and found that 14/32 trees (40%Flowering) are flowering.
We see, with a difference of only 0.06’ (between Panvel and Nerul both in NM), we saw a drastic change!
A CLASSICAL TEST CASE!
What could be the reason for this observation?
Are there any variables? What could be they?
This observation is challenging our whole hypothesis!
@Shraddha CUBE HBCSE Cardamine is yet to share evidence in the form of photos.
Let us see what is it actually!
