Ngā Take e Pā Ana ki te Kanorau o te Moana
Ko te kanorau koiora o te moana ko ngā momo ora e noho ana i roto i ngā pūnaha rauropi wai tote, mai i ngā moroiti pēnei i te plankton, te rimurimu, me ngā huakita ki ngā kararehe nunui pēnei i te mango, te tohorā, me ngā honu moana. Ehara i te mea ko te maha o ngā momo anake te mea e kitea ai tēnei kanorau, engari ko te rerekētanga ira i roto i tētahi momo me te kanorau o ngā pūnaha rauropi moana pēnei i te toka korara, te mangrove, te moenga tarutaru moana, te moana hohonu, me ngā wai porowhita. He mea nui te kanorau koiora o te moana nā te mea e tautoko ana i te mekameka kai, e whakau ana i te āhuarangi, e whakarato ana i ngā puna kai, ā, e tautoko ana hoki i ngā ōhanga o ngā hapori takutai. Heoi, kāore i te ōrite te taumata o te kanorau koiora o te moana, ā, ka taea te huri i roto i te wā. He maha ngā āhuatanga e pā ana ki te taumata o te kanorau koiora o te moana, i te taiao me ngā mahi a te tangata.
1. Te pāmahana me te huringa āhuarangi
Ko te pāmahana te mea matua e whakatau ana i te horapa o ngā momo i roto i te moana. He pai te awhe pāmahana o te nuinga o ngā rauropi moana mō te tipu me te whakaputa uri. Ko te nuinga o ngā wai toropika he nui ake te kanorau koiora i ngā wai porowhita nā te mea ka taea e ngā momo kanorau te urutau me te hanga hononga rauropi uaua nā te pāmahana mahana, pumau. I tetahi atu taha, ko te huringa āhuarangi te take o te mahana o te moana, e akiaki ana i te nekehanga o te nohonga ki ngā pou, e whakarerekē ana i te hanganga o ngā momo, ā, e whakawehi ana i ngā rauropi kāore e taea te urutau.
Haunga te mahana haere, ka puta anō hoki i te huringa āhuarangi ngā ngaru wera o te moana, ka puta ai te mā o te korara. Ina ngaro te rimurimu o ngā korara nā te ahotea wera, ka pakaru pea ngā pūnaha rauropi o te toka korara . He kāinga ngā mano tini o ngā momo kararehe o ngā toka korara . Ki te whakararuraruhia ngā korara, ka tino heke te kanorau koiora e whakawhirinaki ana ki a rātou.
2. Te tote (te nui o te tote)
Ka pāngia te taurite osmotic o ngā rauropi moana e ngā taumata tote. Nā te rerekētanga o te tote i waenga i ngā takutai moana , ngā awaawa, me te moana tuwhera ka hangaia he hapori motuhake o ngā momo. Hei tauira, i roto i ngā awaawa, ka rerekē te tote nā te ranunga o te wai moana me te wai māori. He pai anake ēnei āhuatanga mō ngā rauropi e ātete ana ki ngā rerekētanga, ka iti ake te kanorau koiora mō ētahi momo, engari he ahurei ngā hapori, ā, he wāhi whakatipu mō te tini o ngā ika me ngā kōura.
Ka puta anō hoki ngā panoni tote nā te nui o te ua , te rewa o te huka, te pikinga rānei o te mimiti nā te pāmahana teitei. Ka pā pea ngā panoni tote nui ki te oranga o ngā torongū me ngā hua ika, ka whakararuraru i te tipu o te tarutaru moana, me te whakarerekē i te hanganga o ngā hapori plankton.
3. Te māramatanga me te hohonutanga
Mā te hihi o te rā ka whakatau te hua tuatahi mā te photosynthesis. I roto i te rohe phototic (te paparanga whiwhi mārama o te moana), ka tupu pai te phytoplankton, te rimurimu, me te tarutaru moana, ā, koinei te pūtake o te mekameka kai. Nō reira, he maha ngā momo e huihui ana i roto i ngā wai pāpaku e mārama ana. I tetahi atu taha, i te moana hohonu, he iti noa te mārama, he iti ake ngā rauemi pūngao, ā, me urutau ngā rauropi ki te pēhanga teitei me te pāmahana iti. Ahakoa te āhua o te kanorau koiora o te moana hohonu, he maha ngā momo taketake me ngā momo ahurei kei roto, pērā i ngā ika bioluminescent me ngā rauropi e noho ana i te taha o ngā pūnga waiariki.
Ka pāngia hoki ētahi atu āhuatanga e te hohonutanga pērā i te pēhanga, te pāmahana, me te wātea o te hāora. Mā te huinga o ēnei āhuatanga ka whakatau ko ēhea ngā rauropi ka ora i roto i tētahi paparanga motuhake.
4. Te wātea me te hua o ngā matūkai
Ko ngā matūkai pēnei i te hauota, te whākōkī, me te silicate ka mahi hei "tonga" mō ngā phytoplankton. I ngā wāhi e piki ake ana te wai (te pikinga ake o te wai matao, whai matūkai mai i te hohonutanga ki te mata), ka piki ake te hua, ka hua ake he nui ake te koiora ika me te kaipahua. He mea nui ngā wāhi e piki ake ana te wai nā te mea he nui te kai.
Heoi, mā te nui o ngā matūkai mai i te rerenga o ngā tongi ahuwhenua, o ngā para o te whare rānei, ka arahi pea ki te eutrophication, arā, te puāwaitanga o ngā rimurimu. Ka taea e ētahi puāwaitanga rimurimu te whakaputa paitini, te whakaiti rānei i te hāora (hypoxia) i te mea ka mate, ka pirau hoki ngā rimurimu. Nā ēnei rohe "mate" ka kore e taea te uru atu ki ngā rauropi maha, ā, ka heke tere te kanorau koiora.
5. Hanganga nohoanga: ngā toka korara, ngā mangrove, me ngā moenga tarutaru moana
He mea nui te uaua o te noho hei whakatau i te kanorau koiora. He kapiti, he rua, he mata hoki ngā toka korara hei wāhi whakaruruhau, hei wāhi kai, hei wāhi whakaputa uri hoki mō ngā momo momo. He wāhi pakaru ngaru ngā mangrove, hei wāhi whakatipu ika, pāpaka, me te kōura. He wāhi noho ngā moenga tarutaru moana mō ngā honu me ngā dugong, tae atu ki ngā wāhi kai mō ngā ika ririki.
Ki te whakangaromia ēnei nohanga e te keri onepu, te tango whenua, te tango mangrove, te hī ika whakangaro rānei, ka ngaro ngā nohanga o te tini o ngā momo. He maha ngā wā, ko te whakangaromanga o tētahi nohanga ka puta he tauhohenga mekameka i roto i ētahi atu rauropi, nā te mea e hono tahi ana ēnei e toru, inā koa i ngā takutai moana pārūrū.
6. Ngā ia o te moana me te hononga taupori
He rite ngā au moana ki ngā "huarahi" e hono ana i ngā taupori o ngā rauropi. He maha ngā wā ka haria ngā ika me ngā torongū kore-tāiao mai i tētahi wāhi ki tētahi atu, nō reira he wāhi nui tā ngā au ki te horapa o ngā momo me te whakawhiti ira i waenga i ngā taupori. He mea nui tēnei hononga mō te pupuri i te kanorau ira me te whakateretere i te whakaoranga o te pūnaha rauropi i muri i ngā raruraru.
Heoi, mā ngā panonitanga o ngā tauira o nāianei nā te huringa āhuarangi ka taea te whakarerekē i ngā ara horapa o ngā torongū. Tērā pea ka ngaro te puna torongū o ētahi wāhi, ka heke te taupori, ko ētahi atu ia, ka kitea pea te taenga mai o ngā momo hou, he momo whakaekenga pea.
7. Te pēhanga hī ika me te whakamahinga nui rawa
He tūmomo mōrearea nui te hī ika nui ki te kanorau koiora o te moana. Ina hīia nuitia ngā kaipahua matua pērā i ngā mango me ngā ika nunui, ka pakaru te mekameka kai. Ka pahū te taupori o ētahi kaipahua, ka pēhi i ētahi atu rauropi, ā, ka huri i te pūnaha rauropi katoa. Hei tāpiri, ko ngā tikanga hī ika whakangaro pērā i te hī ika dynamite, te hī ika cyanide rānei, ehara i te mea ka whakaiti noa i te maha o ngā ika, engari ka whakangaro hoki i ngā nohoanga o ngā toka korara.
Ko ētahi atu mahi whakatoi pērā i te tango korara hei whakapaipai, te hopu honu, me te hauhake nui i ētahi momo koiora ka whakaiti i te kanorau, inā koa ko ngā momo e puhoi ana te tipu me te iti o te tere whakaputa uri.
8. Te parahanga moana: te kirihou, ngā matū, me te hinu
He maha ngā pānga o te parahanga ki te kanorau koiora. Ka taea e ngā manu moana, ngā honu, me ngā ika te horomia ngā para kirihou, ka mate, ka raru rānei te whānau uri. Ka taea hoki e ngā kirihou moroiti te uru ki te mekameka kai me te kawe i ngā matū kino. Ka taea e ngā para ahumahi te whai konganuku taumaha pērā i te mercury, e kohia ana i roto i ngā kaipahua o runga. Ka taea e ngā turuturu hinu te kapi i te mata o te wai, ka kino hoki ngā huruhuru manu, ngā pihanga ika, me ngā pūnaha rauropi takutai.
Haunga ngā pānga tika ki ngā rauropi, ka taea hoki e te parahanga te whakakino i te kounga o te nohoanga me te whakararuraru i ngā tukanga rauropi, hei tauira mā te aukati i te photosynthesis, te whakaiti rānei i ngā taumata hāora rewa.
9. Ngā momo me ngā mate urutā
Ka taea e ngā momo whakaeke te whakataetae ki ngā momo taketake mō te kai me te wāhi. Ko te horapa o ngā momo whakaeke ka puta pinepine mai i ngā mahi a te tangata, pērā i te wai taumaha kaipuke, i te mahi ahuwhenua kore whakahaere rānei. Ina uru mai ngā momo ehara i te taketake, ā, ka tupu pai me te kore he kaipahua tūturu, ka heke te kanorau koiora o te rohe i te mea ka nekehia ngā momo taketake.
I tētahi atu taha, ka taea hoki e te mate te whakarerekē i ngā hapori moana. Ka taea e ngā pakarutanga mate i roto i ngā korara, i ngā wheturangi rānei te whakangaro i ngā pūnaha rauropi nui. Ka taea e ngā āhuatanga taiao taumaha, pērā i te pāmahana teitei, te parahanga rānei, te whakanui ake i te ngāwari o ngā rauropi ki te pāngia e te mate.
10. Te whakakawa i te moana
Ka mimiti te moana i ētahi hauhā waro (CO₂) mai i te āhuarangi. I te pikinga ake o ngā taumata CO₂, ka nui ake te waikawa o te wai moana, ka pā ki ngā rauropi e hanga angaanga ana, e hanga angaanga ana rānei mai i te konupūmā waro, pērā i ngā korara, ngā mātaitai, me ētahi plankton. Mēnā ka ngoikore ngā rauropi matua e hanga ana i ngā nohoanga pērā i ngā korara, ka puta he pānga domino ki te kanorau koiora. Ka pā hoki te waikawa ki ngā whanonga ika, tae atu ki ngā pūkenga whakatere me ngā urupare ki ngā kaipahua.
Whakamutunga
Ka pāngia te kanorau koiora o te moana e te taunekeneke o ngā āhuatanga ā-tinana, ā-matū, ā-koiora, tae atu ki ngā pēhanga mai i ngā mahi a te tangata. Ko ngā āhuatanga taiao pēnei i te pāmahana, te tote, te mārama, te hohonu, ngā matūkai, ngā ia, me te uaua o te nohonga ka hanga i ngā tauira tohatoha o ngā mea ora o te moana. I taua wā, ko te huringa āhuarangi, te parahanga, te whakamahinga nui rawa, te whakangaromanga o ngā nohonga, ngā momo whakaeke, ngā mate, me te waikawa o te moana kei te whakatere i te hekenga o te kanorau koiora. He mea nui te mārama ki ēnei āhuatanga hei whakatinana i ngā mahi tiaki tika, pēnei i te whakahaere hī ika pumau, te tiaki i ngā wāhi tiaki moana , te whakaiti i ngā para kirihou, te whakaora i ngā mangrove me ngā toka korara, me te whakaiti i ngā tukunga waro. Ehara i te mea ko te moana hauora anake te kāinga mō ngā miriona momo, engari ko te tūāpapa hoki o te oranga tangata i runga i te Ao.
