Qhov sib txawv ntawm tus yuam sij dichotomous thiab tus yuam sij taxonomic yog qhov tseem ceeb dichotomous yog tus lej cim npe nrov tshaj plaws uas pab txhawb kev txheeb xyuas tus neeg tsis paub thaum tus yuam sij taxonomic yog cov cuab yeej yooj yim siv los txheeb xyuas cov khoom tshwj xeeb.
Key yog ib qho cuab yeej siv los txheeb xyuas lub cev. Nws muaj cov ntaub ntawv hais txog hom. Yog li ntawd, lub hom phiaj tseem ceeb ntawm tus yuam sij yog los pab txhawb kev txheeb xyuas cov kab mob kom nws txawv ntawm lwm yam kab mob. Qee zaum, nws yuav tsis muab cov ntaub ntawv hais txog evolution lossis phylogenetic kev sib raug zoo. Xws li tus yuam sij yog hu ua tus yuam sij taxonomic. Muaj ob peb hom taxonomic yuam sij. Ntawm lawv, tus yuam sij dichotomous yog cov cuab yeej txheeb xyuas nrov tshaj plaws. Tus yuam sij dichotomous muaj cov lus sib txuas ua ke.
Dichotomous Key yog dab tsi?
Tus yuam sij dichotomous yog ib qho cuab yeej siv los ntawm biologists ua tus qhia thaum lawv xav txheeb xyuas tus neeg. Nws pab txheeb xyuas cov kab mob uas tsis paub, tshwj xeeb tshaj yog cov nroj tsuag lossis tsiaj. Raws li lub npe "dichotomous" qhia, nws muaj cov nqe lus muaj ob txoj kev xaiv uas piav txog cov yam ntxwv tseem ceeb ntawm cov kab mob uas tsis paub. Yog li ntawd, tus yuam sij no ib txwm muaj ob ntu. Txhua kauj ruam muaj ob txoj kev xaiv. Tus neeg siv yuav tsum xaiv qhov zoo tshaj plaws piav qhia ntawm ob txoj kev xaiv thiab txav mus raws tus yuam sij kom txog thaum nws txheeb xyuas cov kab mob uas tsis paub. Thaum ib nqe lus teb, cov nqe lus tom ntej tuaj yeem teb tau. Thaum kawg, qhov tseem ceeb dichotomous txheeb xyuas cov tsiaj tshwj xeeb los ntawm lawv lub npe kev tshawb fawb tshwj xeeb thiab tseem yog tsev neeg cov kab mob twg.
Daim duab 01: Dichotomous Key
Feem ntau, cov yuam sij dichotomous yog siv thaum ob hom zoo ib yam li ib leeg. Txawm li cas los xij, tus yuam sij dichotomous tsis muab cov ntaub ntawv hais txog evolution lossis phylogenetic kev sib raug zoo.
Dab tsi yog Taxonomic Key?
Tus yuam sij taxonomic yog ib qho cuab yeej uas pab tib neeg txheeb xyuas cov nroj tsuag lossis tsiaj tsis paub. Nws yog tus yuam sij tsim kom raug. Qhov tseem ceeb muaj cov ntaub ntawv tseem ceeb txog cov hom. Tus neeg siv yuav tsum ua tib zoo hla tus yuam sij thiab xaiv cov lus piav qhia zoo tshaj plaws ntawm cov qauv thiab txav mus rau hauv cov lus piav qhia tom ntej.
Muaj peb hom taxonomic yuam sij. Lawv yog tus yuam sij dichotomous, tus yuam sij polyclave (tseem hu ua ntau yam nkag lossis synoptic), thiab qhov tseem ceeb tshwm sim. Cov yuam sij Dichotomous yog qhov ntau tshaj plaws thiab muaj cov kab sib txuas. Polyclave keys yog ib qho tshiab rau cov yuam sij dichotomous. Lawv tau dhau los ua neeg nyiam vim qhov yooj yim ntawm computerizing lawv. Polyclave key tso cai rau tus neeg siv nkag mus rau tus yuam sij ntawm txhua qhov chaw.
Dab tsi yog qhov zoo sib xws ntawm Dichotomous Key thiab Taxonomic Key?
- Lawv ob leeg yog tus yuam sij pov thawj.
- Qhov tseeb, tus yuam sij dichotomous yog tus yuam sij taxonomic.
Qhov txawv ntawm Dichotomous Key thiab Taxonomic Key yog dab tsi?
Tus yuam sij dichotomous yog cov cuab yeej uas muaj cov lus sib txuas txhawm rau txheeb xyuas cov kab mob tsis paub. Tus yuam sij taxonomic yog ib qho cuab yeej yooj yim siv los txheeb xyuas cov khoom tshwj xeeb. Yog li, qhov no yog qhov sib txawv ntawm tus yuam sij dichotomous thiab taxonomic key.
Ntxiv mus, tus yuam sij dichotomous, uas yog hom kev sau se, ib txwm muaj ob txoj kev xaiv, thaum cov yuam sij taxonomic yuav muaj ob lossis ntau txoj kev xaiv. Tsis tas li ntawd, cov yuam sij polyclave, lwm yam ntawm cov yuam sij taxonomic, yog tsim los siv cov khoos phis tawj, tsis zoo li cov yuam sij dichotomous. Tsis tas li ntawd, tus yuam sij polyclave tso cai rau cov neeg siv nkag mus rau hauv tus yuam sij ntawm txhua qhov chaw, tab sis tus yuam sij dichotomous tsis tso cai nkag mus.
Hauv qab no yog cov lus qhia luv luv ntawm qhov sib txawv ntawm tus yuam sij dichotomous thiab tus yuam sij taxonomic.
Summary – Dichotomous Key vs Taxonomic Key
Tus yuam sij taxonomic yog ib qho cuab yeej uas pab txheeb xyuas cov kab mob tshwj xeeb. Muaj ob peb hom taxonomic yuam sij. Ntawm lawv, tus yuam sij dichotomous yog cov cuab yeej nrov tshaj plaws uas muaj cov lus sib txuas. Nws tso cai rau kev txheeb xyuas cov hom tsis paub. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm dichotomous key thiab taxonomic key.
