Qhov Tseem Ceeb Qhov txawv - Euryhaline vs Stenohaline
Osmoregulation, nws yog txheej txheem los ntawm cov kab mob nquag tswj hwm cov dej theem hauv nws txoj kev nyob tsis hais qhov chaw sab nraud. Homeostasis ntawm lub cev cuam tshuam nrog kev tswj hwm osmotic siab nyob rau theem tsis tu ncua uas nws tiv thaiv cov kua hauv lub cev tau txais cov concentrated lossis diluted dhau lawm. Hais txog lub ntsiab osmoregulatory mechanisms, muaj ob hom loj xws li osmoconformers thiab osmoregulators. Hauv qab osmoconformers, cov kab mob stenohaline suav nrog, thiab nyob rau hauv osmoregulators, cov kab mob euryhaline suav nrog. Euryhaline kab mob muaj peev xwm ciaj sia nyob rau hauv ntau ntau ntawm salinity concentrations thaum stenohaline kab mob ciaj sia tsuas yog nyob rau hauv ib tug qis ntau ntawm ntsev concentration. Qhov no yog qhov sib txawv tseem ceeb ntawm Euryhaline thiab Stenohaline.
Euryhaline yog dab tsi?
Euryhaline kab mob txhais tau tias yog cov kab mob uas muaj peev xwm ua kom muaj sia nyob ntau yam ntsev ntau. Yog li ntawd, cov kab mob no yog ib txwm hloov mus rau kev vam meej hauv dej ntsev, dej brackish thiab dej tshiab. Lawv tau yoog rau cov ntsev ntau ntau vim lawv muaj peev xwm tshwj xeeb hauv osmoregulation. Lawv tseem hu ua osmoregulators. Cov osmoregulators muaj peev xwm tswj tau cov dej hauv lawv lub cev tsis hais qhov chaw sab nraud. Qhov no tiv thaiv kab mob los ntawm kev nkag los yog poob dej ntau ntxiv vim yog kev mob sab nraud.

Feem ntau cov kab mob euryhaline muaj nyob hauv cov estuaries thiab cov pas dej ua ke. Hauv cov chaw nyob no, ntsev concentration hloov zuj zus. Qee cov kab mob muaj nyob rau hauv pawg euryhaline no vim lawv lub neej voj voog. Ua raws li lawv lub neej voj voog, cov kab mob no yuav tsum tau txav mus rau hauv dej tshiab thiab dej hiav txwv ntawm qee theem ntawm lawv lub neej. Piv txwv ntawm xws li euryhaline kab mob yog salmon thiab eels. Raws li cov lus xaus, qhov tshwj xeeb ntawm cov kab mob osmoregulatory euryhaline yog tias lawv muaj peev xwm tswj tau cov dej hauv lub cev ntawm cov theem tsis tu ncua tsis hais txog sab nraud ib puag ncig thiab lawv muaj sia nyob hauv thaj chaw uas cov ntsev sib txawv ntawm ntau dua.
Stenohaline yog dab tsi?
Stenohaline kab mob txhais tau tias yog cov kab mob uas muaj peev xwm zam tau qhov kev hloov pauv hauv cov dej ntsev ntawm qhov txwv lossis nqaim. Lawv tsis ciaj sia nyob rau hauv ib puag ncig tej yam kev mob uas cov saline concentration txawv sai heev. Cov ntsev kam rau ntawm cov kab mob stenohaline sib txawv ntawm cov hom. Qee hom muaj xws li cov ntses dej qab zib xws li ntses goldfish tsis muaj peev xwm ciaj sia nyob rau hauv cov chaw uas muaj ntsev ntau xws li dej hiav txwv. Vice versa, tib txoj cai yog siv rau cov kab mob uas muaj nyob rau hauv cov chaw nyob nrog high saline concentrations. Lawv tsis vam meej nyob rau hauv cov dej tshiab.
Daim duab 02: Stenohaline Goldfish
Feem ntau ntawm cov kab mob stenohaline tseem hu ua osmoconformers. Osmoconformers txhais tau tias yog cov kab mob uas qhov osmolarity ntawm lawv cov kab ke nyob tsis hloov raws li cov kua qaub concentration ntawm sab nraud ib puag ncig. Tsis zoo li cov kab mob euryhaline, cov kab mob stenohaline tsis muaj peev xwm ciaj sia nyob hauv ib puag ncig cov ntsev ntau hloov pauv lub sijhawm. Yog li ntawd, cov kab mob stenohaline xws li ntses tsis tsiv ntawm ib qho chaw mus rau lwm qhov. Txij li thaum lawv tsis muaj peev xwm tswj hwm qhov sib txawv ntawm cov ntsev, cov kab mob stenohaline siv tsawg zog rau osmoregulation. Piv txwv ntawm cov kab mob stenohaline yog goldfish thiab haddock ntses. Goldfish yog hom dej tshiab thaum cov ntses haddock yog hom dej hiav txwv.
Qhov Zoo sib xws ntawm Euryhaline thiab Stenohaline yog dab tsi?
- Ob leeg euryhaline thiab stenohaline kab mob yog cov kab mob hauv dej.
- Ob hom euryhaline thiab stenohaline yog categorized raws li lub peev xwm kom muaj sia nyob ntawm haline concentrations.
Qhov txawv ntawm Euryhaline thiab Stenohaline yog dab tsi?
Euryhaline vs Stenohaline |
|
| Cov kab mob uas muaj peev xwm ua kom muaj sia nyob ntau dua ntawm salinity yog hu ua euryhaline. | Cov kab mob uas muaj sia nyob hauv qhov nqaim ntawm cov ntsev ntsev yog hu ua stenohaline kab mob. |
| Piv txwv | |
| Ntsuab chromide, Mummichog, salmon yog cov piv txwv ntawm cov kab mob euryhaline. | kub ntses, ntses haddock yog cov piv txwv ntawm cov kab mob stenohaline. |
Summary – Euryhaline vs Stenohaline
Osmoregulation cuam tshuam txog kev tswj hwm cov dej hauv cov txheej txheem nyob tsis hais txog cov ntsiab lus dej ntawm ib puag ncig ib puag ncig. Ntau hom kab mob sib txawv siv cov txheej txheem sib txawv rau osmoregulation. Yog li ntawd, nyob rau hauv cov ntsiab lus ntawm osmoregulation, hom yuav muab faib ua ob pawg; osmoconformers thiab osmoregulators. Hauv qab osmoconformers, cov kab mob stenohaline suav nrog, thiab nyob rau hauv osmoregulators euryhaline kab mob suav nrog. Euryhaline kab mob muaj peev xwm ciaj sia nyob rau hauv ntau qhov sib txawv ntawm cov ntsev thaum cov kab mob stenohaline vam meej ntawm qhov txwv tsis pub muaj ntsev. Qhov no yog qhov txawv ntawm euryhaline thiab stenohaline.
