planet ant (doc)
9 min – each ant has a role to play
10 min – a thriving working colony from wild.. in order to observe their org techniques et al..
11 min – we can get away with not brining all the ants back.. but not the queen.. failure w/o her
14 min – maze of chambers connected by a system of tunnels..
18 min – survived the journey.. now we’re hoping that they’ll take over and complete the building of their new world.. after settling.. we join up the colony to the foraging space
23 min – a large colony can consume the same weight of vegetation a day as a cow
24 min – cut in arc of circle.. so bigger ants carry bigger loads
26 min – 18th cent.. begin intrigue.. mostly from clergy… 1\ industrious workers 2\ mutual aide.. help/support
28 min – thomas belt – 1878 – finds leafcutters.. what he was looking for in people mining
29 min – ants.. as one large raft.. built from their own bodies.. can survive like this for months.. waiting for dry land
secrets of the fire ants raft… georgia tech (nathan mlot) .. faq: what happens to ants on bottom.. trap layer of air.. so all ants.. even on bottom.. are not in water… each ant repellant to water… 1000s combined.. unsinkable..
30 min – when they are pushed under water.. go tighter together.. subjected to high pressures under water.. still keeps water out
31 min – ants own body has tentacles all over.. so can connect to any other ant anywhere… so can make themselves all a single structure.. cooperation has made them an engineering marvel of the modern world..
33 min – ant landfill… garbage and dead bodies… these are kept way below.. because when in such high abundance in colony.. don’t want diseases to spread.. so anything that could possibly rot is removed
35 mi – queen is colony’s most prized member.. but does that mean she’s in charge..?
36 min – lays up to 30 000 eggs a day
37 min – once/year produce new queens.. but they leave.. and start own colony.. also only time produce males.. and their sould purpose is to mate… so in colony.. all ants are female/sisters
38 min – all eggs are the same.. so totally how much food larvae is given that determines what it (size ant) turns into
39 min – they respond to what’s happening to them.. ie: if we start distrubing the colony.. they start producing more soldiers.. they’re responding to lives/heat/food/what queen’s doing… and all that info is somehow integrated together in the workers.. because it’s all about the workers.. not the queen..
so very particular form of social org.. queen is only one that reproduces..
40 min – each generation raises next from egg to ant.. results in multiple generations working together for the good of the colony
being eusocial is one of most important evolutionary elements in animal kingdom
Eusociality (Greekeu: “good/real” + “social”), the highest level of organization of animal sociality, is defined by the following characteristics: cooperative brood care (including brood care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes called castes. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste.
Eusociality exists in certain insects, crustaceans and mammals. It is mostly observed and studied in the Hymenoptera(ants, bees, and wasps) and in the termites. A colony has caste differences: queens and reproductive males take the roles of the sole reproducers, while soldiers and workers work together to create a living situation favorable for the brood. In addition to Hymenoptera and Isoptera, there are two known eusocial vertebrates among the rodents: the naked mole-rat and the Damaraland mole-rat. Some shrimps, such as Synalpheus regalis, are also eusocial. E. O. Wilson has claimed that humans are eusocial, but his arguments have been refuted by a large number of evolutionary biologists, who note that humans do not have division of reproductive labor.
Several other levels of animal sociality have been distinguished. These include presocial (solitary but social), subsocial, and parasocial (including communal, quasisocial, and semisocial).
43 min – when ants become highly highly social.. they become a very dominant life form..
44 min – ants have been called ecosystem engineers as they can change the environment around them..
you might say that its eusociality that feeds our world..
45 mmin – incredible growth of the fungus gardens.. a miracel of micro engineering..
46 min – white tufts from the fungus feed the colony.. just the right nutrients for the developing brood
clearest indication yet that our leafcutting colony is thriving..
useful to human measures.. enough nutrients for all
48 min – showing org on a massive scale.. and that begs an important question.. how do they org all this.. how do they know what to do.. *humans wouldn’t be able to do this w/o some kind of hierarchy..w/o somebody giving instructions..
i believe *that is myth.. i believe.. we believe that.. because we’ve never trusted us in a .. rat park.. like we trust the ants.. we’ve never gone and left ourselves with all the resources and no management…. for equiv of ant’s 10-15 days.. so.. i believe.. we’ve never really seen us.. as one
not the case w ants.. there is no hierarchy.. no central control.. from any individual or group.. not even the queen… so how do the ants do it..
49 min – adam tests them.. how do they know where to go when can’t see the food.. eye sight isn’t good enough.. instead..
it’s *the ingenius way the ants share their info with each other..**using their acute sense of smell
moving ants leave a *chemical pheromone trail..that **marks the way for other ants
50 min – ants leave trail on way to food (for sister ants) if finds food.. lay down even more pheromone on way back *making trail even stronger… if doesn’t find food.. no additional pheromone.. and trail simply evaps away.. .. **1000s of ants doing this.. makes trails to food very strong..
*same true for connections that work.. sign connection was more true.. more eudaimoniative..
**so same to individual curiosity… more eudaimoniative…. stronger trail.. so finding more of tribe.. et al..
and that (the strong pheromone trail) means the ants can org themselves..
h u g e
the queens not in colony going ..go and say.. right turn.. left.. take..the third exit…
51 min – so each individual ant is dealing with simple signals/rules.. but collectively this system receives complex results..
it enables the colony to find new food sources. . exploit them efficiently.. and react swiftly when they’re depleted.. this is what underpines the entire leaf cutting operation..
pheromones aren’t only way leafcutters communicate.. they’re constantly exchanging info..
and with right tech.. we can even listen in..
h u g e
52 min – magnification of sounds…. w/in.. stridulation.. sounds of rubbing two sections of abdomen together.. little chirp
53 min – that little chirpy noise is a recruitment signal.. the more nutritious a leaf is.. the more the ant makes this noise.. sending a cascade of vibrations through the plant
54 min – risk of roof collapse.. sound of ant fear.. causes specific behaviour.. come over here.. dig me out.. alarm call..
55 min – because they’re so small.. *we can’t hear them w/o fancy microphones and things .. but once you start hearing them…**you realize they’re living in a very complicated world..
*many humans.. why we need a mech to facil hearing us.. at least temporarily ..
** never nothing going on ness
so this is how ants org selves..*each ant follows simple rules.. **using communication tools… pheromones/stridations.. ***allow colony to solve complex problems.. this is collective swarm intelligence..
56 min – complex problems: house hunting.. a matter of life and death
58 min – talking slum et al.. finding better spaces
reminds me of iwan baan
then video ends.. and can’t find 2nd part.. says it’s 90 min.. so missing 30 min..
