Photosynthesis of Zooxanthellae: The Core of Symbiosis
Feem ntau ntawm cov pob zeb reef- tsim corals chaw nres nkoj microscopic zooxanthellae hauv lawv cov ntaub so ntswg. Corals muab chaw nyob thiab metabolites rau cov symbionts, thaum zooxanthellae muab txog li 90% ntawm coral lub zog los ntawm photosynthesis. Lub teeb tsis txaus txo cov khoom tsim tau zooxanthellae, ua rau coral "kev tshaib kev nqhis." Hloov pauv, ntau lub teeb los yog qhov tsis zoo tuaj yeem ua rau zooxanthellae overgrowth lossis kev ntxhov siab, ua rau coral bleaching.
Ntsiab Spectral Component Analysis
Lub teeb xiav (400-500nm): Qhov no tsim lub hauv paus ntawm coral teeb pom kev zoo. Sib sib zog nqus xiav / huab tais xiav lub teeb (420-450nm) muaj qhov nkag tau zoo tshaj plaws thiab tau txais txiaj ntsig zoo los ntawm zooxanthellae rau photosynthesis. Nws kuj zoo siab rau coral fluorescent proteins (xws li, GFP, DsRed), ua cov xim fluorescent zoo li npau suav.
Violet/UV-A (380-420nm): Nruab nrab UV-A ntxiv txhawb qee cov corals los tsim cov xim zoo nkauj (piv txwv li, ntshav, liab) uas ua raws li "tshuaj pleev thaiv hnub" los tiv thaiv cov ntaub so ntswg. Kev txhaj tshuaj yuav tsum tau ua tib zoo tswj, vim tias qhov ntau dhau yog teeb meem.
Lub Teeb Dawb thiab Tag Nrho Spectrum: Lub teeb dawb (ib qho sib xyaw ntawm xiav, ntsuab, thiab liab) yog qhov tseem ceeb rau kev muab lub hnub ci zoo nkauj, txhawb nqa tag nrho coral kev noj qab haus huv thiab kev loj hlob, thiab txhim kho xim. Nws pab nthuav tawm lub coral "pem xim" lossis xim tseeb.
Lub teeb liab thiab ntsuab (500-600nm): Lub teeb liab nruab nrab (620-700nm) ntseeg tau tias yuav pab coral kev loj hlob thiab symbiont pej xeem ntom, tab sis ntau dhau los txhawb qis algae proliferation. Lub teeb ntsuab (~ 550nm) ua kom pom qhov sib txawv thiab xim nplua nuj.
Kev siv lub teeb thiab kev xav txog lub sijhawm Photo
Kev siv zog (PAR Values): Cov kev xav tau sib txawv ntawm cov corals. Cov corals mos thiab LPS corals feem ntau xav tau lub teeb nruab nrab (PAR 75-150), thaum SPS corals xav tau lub teeb muaj zog heev (PAR 200-400+). PAR qhov tseem ceeb yuav tsum tau muab raws li lub coral qhov chaw tso rau hauv lub tank (siab, nruab nrab, los yog tsawg lub teeb zones).
Photoperiod: Simulating ntuj hnub tuaj / hnub poob yog qhov tseem ceeb. Lub voj voog ib txwm muaj 8-10 teev ntawm lub teeb pom kev zoo ntawm cov teeb pom kev zoo los ntawm ob peb teev thaum kaj ntug / tsaus ntuj (lub teeb xiav siv tsawg) lub sijhawm. Qhov no txo qis coral kev nyuaj siab thiab tso cai rau kev soj ntsuam ntawm lawv cov fluorescence nyob rau hauv lub teeb xiav.
Cov tswv yim tswv yim thiab kev xaiv cov khoom siv
Spectral Ratio: Ib qho pib taw qhia yog xiav -violet rau dawb lub teeb piv ntawm 2: 1 thiab 3: 1. Piv txwv li, thaum lub sij hawm tseem ceeb teeb pom kev zoo, lub teeb xiav yog teem rau ntawm 80% -90%, thaum lub teeb dawb siv yog teem ntawm 30% -40%.
Dynamic Lighting: Leverage LED programmability to varied spectrum and intensity in the day -tasting blue-violet light thaum sawv ntxov, nce lub teeb dawb siv thaum nruab hnub los simulate tav su, thiab rov qab mus rau xiav -violet lub teeb thaum yav tsaus ntuj.
Hnav khaub ncaws thiab ntxoov ntxoo: xyuas kom lub teeb sib npaug ntawm tag nrho lub tank thaum tso cai rau thaj chaw ntxoov ntxoo los muab qhov chaw nkaum rau lub teeb - cov kab mob rhiab heev (xws li, qee yam anemones, paj hlwb corals).
Rau reef tanks dominated los ntawm SPS corals, siab - siv LEDs los yog hlau halide teeb nrog meej spectrums yog qhov kev xaiv. Rau cov tso tsheb hlau luam uas muaj LPS thiab mos coral, nruab nrab- siv LEDs lossis T5HO teeb pom kev zoo yuav zoo dua thiab yooj yim rau kev tswj.
