These bees are in my backyard in Berkeley, California.
1
26325

Ove pčele su u mom dvorištu u Berkliju u Kaliforniji.
00:30
Until last year, I'd never kept bees before,
2
30822
2399
Do prošle godine, nikada nisam držao pčele,
00:33
but National Geographic asked me to photograph a story about them,
3
33221
4049
ali Nacionalna geografija me je zamolila da fotografišem prilog o njima
00:37
and I decided, to be able to take compelling images,
4
37270
2499
i odlučio sam, kako bih napravio uverljive slike,
00:39
I should start keeping bees myself.
5
39769
2484
da treba i sam da držim pčele.
00:42
And as you may know,
6
42253
1695
Kao što možda znate,
00:43
bees pollinate one third of our food crops,
7
43948
2624
pčele oprašuju jednu trećinu naših useva
00:46
and lately they've been having a really hard time.
8
46572
3158
i u poslednje vreme im je prilično teško.
00:49
So as a photographer, I wanted to explore what this problem really looks like.
9
49730
4551
Kao fotograf, želeo sam da istražim kako ovaj problem zapravo izgleda.
00:54
So I'm going to show you what I found over the last year.
10
54281
3185
Pokazaću vam šta sam otkrio tokom prošle godine.
00:58
This furry little creature
11
58276
1624
Ovo čupavo malo stvorenje
00:59
is a fresh young bee halfway emerged from its brood cell,
12
59900
4343
je mlada pčelica koja je izmilela napola iz svog legla
01:04
and bees right now are dealing with several different problems,
13
64243
3040
a pčele trenutno imaju posla sa nekoliko različitih problema,
01:07
including pesticides, diseases, and habitat loss,
14
67283
4252
uključujući pesticide, zaraze i gubitak staništa,
01:11
but the single greatest threat is a parasitic mite from Asia,
15
71535
4611
ali najveća pretnja im je parazitska grinja iz Azije,
01:16
Varroa destructor.
16
76146
2329
Varroa destructor.
01:18
And this pinhead-sized mite crawls onto young bees
17
78475
2879
A ova grinja veličine čiode se prikrade mladim pčelama
01:21
and sucks their blood.
18
81354
2345
i isisava njihovu krv.
01:23
This eventually destroys a hive
19
83699
1997
Ovo na kraju uništava košnicu
01:25
because it weakens the immune system of the bees,
20
85696
3244
jer slabi imuni sistem pčela
01:28
and it makes them more vulnerable to stress and disease.
21
88940
3536
i čini ih još podložnijim stresu i bolestima.
01:33
Now, bees are the most sensitive
22
93776
1997
Pčele su najosetljivije
01:35
when they're developing inside their brood cells,
23
95773
2740
kada se razvijaju unutar svojih ćelija legla
01:38
and I wanted to know what that process really looks like,
24
98513
3111
i želeo sam da znam kako taj proces zaista izgleda
01:41
so I teamed up with a bee lab at U.C. Davis
25
101624
2624
pa sam zajedno sa laboratorijom za pčelarstvo na Univerzitetu Dejvis,
01:44
and figured out how to raise bees in front of a camera.
26
104248
3095
otkrio kako da uzgajam pčele ispred fotoaparata.
01:47
I'm going to show you the first 21 days of a bee's life
27
107993
2988
Pokazaću vam prvi 21 dan u životu pčele
01:50
condensed into 60 seconds.
28
110981
2789
sabijen u 60 sekundi.
01:55
This is a bee egg as it hatches into a larva,
29
115763
4804
Ovo je jaje pčele koje se leže u larvu
02:00
and those newly hatched larvae swim around their cells
30
120567
4445
i sveže izležene larve plivaju u svojim ćelijama,
02:05
feeding on this white goo that nurse bees secrete for them.
31
125012
4323
hraneći se belom tečnošću koju za njih luče pčele dadilje.
02:11
Then, their head and their legs slowly differentiate
32
131616
4543
Onda polako počinju da se razlikuju njihove glave i tela
02:16
as they transform into pupae.
33
136159
3350
dok se transformišu u pupe.
02:21
Here's that same pupation process,
34
141833
2020
Evo istog tog procesa pupljenja
02:23
and you can actually see the mites running around in the cells.
35
143853
3390
i zapravo možete da vidite kako grinje trčkaraju po ćelijama.
02:27
Then the tissue in their body reorganizes
36
147243
4267
Onda se reorganizuje tkivo u njihovim telima
02:31
and the pigment slowly develops in their eyes.
37
151510
4605
i polako se razvija pigment u njihovim očima.
02:38
The last step of the process is their skin shrivels up
38
158869
5888
Poslednji korak procesa je taj da se njihova koža smežura
02:44
and they sprout hair.
39
164757
2488
i narastu im dlake.
02:47

03:00
So -- (Applause)
41
180805
2854
Dakle - (Aplauz)
03:06
As you can see halfway through that video,
42
186703
3204
Kako možete videti na polovini tog snimka,
03:09
the mites were running around on the baby bees,
43
189907
2554
grinje su trčale oko malih pčela,
03:12
and the way that beekeepers typically manage these mites
44
192461
3929
a pčelari obično rešavaju problem sa ovim grinjama
03:16
is they treat their hives with chemicals.
45
196390
3014
tako što košnice prskaju hemikalijama.
03:19
In the long run, that's bad news,
46
199404
2266
Na duge staze, to su loše vesti,
03:21
so researchers are working on finding alternatives
47
201670
3553
tako da istraživači rade na pronalaženju alternativnih rešenja
03:25
to control these mites.
48
205223
2164
kako bi se kontrolisale ove grinje.
Ovo je jedno od tih rešenja.
03:28
This is one of those alternatives.
49
208195
2768
03:30
It's an experimental breeding program at the USDA Bee Lab in Baton Rouge,
50
210963
4365
To je eksperimentalni program uzgoja u Laboratoriji za pčele
Ministarstva poljoprivrede SAD u Baton Ružu
03:35
and this queen and her attendant bees are part of that program.
51
215328
3717
a ova kraljica i njene pčele sluge deo su tog programa.
03:39
Now, the researchers figured out
52
219735
3695
Istraživači su otkrili da neke od pčela
03:43
that some of the bees have a natural ability to fight mites,
53
223430
3722
imaju prirodnu sposobnost borbe protiv grinja,
03:47
so they set out to breed a line of mite-resistant bees.
54
227152
4170
pa su krenuli da uzgoje vrstu pčela koja je otporna na grinje.
03:52
This is what it takes to breed bees in a lab.
55
232782
2636
Ovo je potrebno da bi se pčele uzgajale u laboratoriji.
03:55
The virgin queen is sedated
56
235418
2740
Kraljica koja je nevina se uspava
03:58
and then artificially inseminated using this precision instrument.
57
238158
5042
i onda veštački oplodi koristeći ovaj precizni instrument.
04:03
Now, this procedure allows the researchers
58
243200
2278
Ovaj zahvat istraživačima dozvoljava
04:05
to control exactly which bees are being crossed,
59
245478
5022
da kontrolišu tačno koje pčele se ukrštaju
04:10
but there's a tradeoff in having this much control.
60
250500
3127
ali postoji kompromis kada imate ovoliko kontrole.
04:13
They succeeded in breeding mite-resistant bees,
61
253627
3205
Uspeli su da stvore pčele koje su otporne na grinje
04:16
but in that process, those bees started to lose traits
62
256832
3088
ali su u tom procesu te pčele počele da gube svojstva
04:19
like their gentleness and their ability to store honey,
63
259920
3765
poput nežnosti i mogućnosti da čuvaju med,
04:23
so to overcome that problem,
64
263685
2509
pa kako bi zaobišli taj problem,
04:26
these researchers are now collaborating with commercial beekeepers.
65
266194
3548
ovi istraživači sada sarađuju sa komercijalnim pčelarima.
04:30
This is Bret Adee opening one of his 72,000 beehives.
66
270252
4868
Ovo je Bret Adi koji otvara jednu od svojih 72 000 košnica.
04:35
He and his brother run the largest beekeeping operation in the world,
67
275120
4630
On i njegov brat vode najveću pčelarsku operaciju na svetu,
04:39
and the USDA is integrating their mite-resistant bees into his operation
68
279750
5659
i Ministarstvo poljoprivrede SAD ubacuje svoje pčele otporne na grinje u operaciju
04:45
with the hope that over time,
69
285409
1643
nadajući se da će vremenom
04:47
they'll be able to select the bees that are not only mite-resistant
70
287052
3671
moći da odaberu pčele koje su ne samo otporne na grinje,
04:50
but also retain all of these qualities that make them useful to us.
71
290723
4984
već zadržavaju i ostale osobine koje ih čine korisnim za nas.
04:56
And to say it like that
72
296165
1695
Kada se to tako kaže,
04:57
makes it sound like we're manipulating and exploiting bees,
73
297860
3297
ispada kao da manipulišemo pčelama i iskorišćavamo ih,
05:01
and the truth is, we've been doing that for thousands of years.
74
301157
3436
ali istina je da to radimo već hiljadama godina.
05:04
We took this wild creature and put it inside of a box,
75
304593
5154
Uzeli smo ovo divlje stvorenje i stavili smo ga u kutiju,
05:09
practically domesticating it,
76
309747
2114
praktično smo ga pripitomili,
05:11
and originally that was so that we could harvest their honey,
77
311861
4109
i to je prvobitno bilo zbog toga da bismo skupljali njihov med,
05:15
but over time we started losing our native pollinators,
78
315970
2755
ali smo tokom vremena počeli da gubimo prirodne oprašivače
05:18
our wild pollinators,
79
318725
1695
i divlje oprašivače
05:20
and there are many places now where those wild pollinators
80
320420
3065
i sada postoje mnoga mesta gde divlji oprašivači
05:23
can no longer meet the pollination demands of our agriculture,
81
323485
3799
ne mogu više da zadovolje potražnju naše poljoprivrede
05:27
so these managed bees have become an integral part of our food system.
82
327284
5224
tako da su ove ukroćene pčele postale ključni deo našeg sistema hrane.
05:32
So when people talk about saving bees,
83
332508
2719
Kada ljudi pričaju o spašavanju pčela,
05:35
my interpretation of that
84
335227
2133
moje tumačenje toga
05:37
is we need to save our relationship to bees,
85
337360
3228
je da moramo da sačuvamo našu vezu sa pčelama,
05:40
and in order to design new solutions,
86
340588
5004
a kako bismo našli nova rešenja,
05:45
we have to understand the basic biology of bees
87
345592
5101
moramo da razumemo osnovnu biologiju pčela
05:50
and understand the effects of stressors that we sometimes cannot see.
88
350693
6243
kao i efekte stresora koje ponekad ne možemo da vidimo.
05:57
In other words, we have to understand bees up close.
89
357909
3205
Drugim rečima, moramo da pčele razumemo izbliza.
06:01
Thank you.
90
361114
2270
Hvala vam.
