IMarsilea Egyptian iyinhlobo yefern, engezezitshalo ezivikelwe ngokukhethekile. Isitshalo esinjalo se-amphibian esivame ukutholakala ezindaweni ezinjalo:
- IGibhithe;
- Kazakhstan;
- ukufinyelela okuphansi kweVolga;
- I-Astrakhan;
- ENingizimu-mpumalanga Asia;
- I-China.
Inhlabathi ekahle kakhulu yokuhluma yile:
- Ukudangala kwesihlabathi esinamagquma kuyoma ngenkathi yehlobo;
- ugu olunesihlabathi, kodwa kuphela imizimba yamanzi anosawoti;
- izicathulo ezinesihlabathi ezinosilika.
Ukwehla kwenani labantu kuthonywe kakhulu yilokhu:
- ukunyathelwa kwezindawo zokukhula yimfuyo;
- ukungcoliswa kwemvelo yizilwane;
- ukungcoliswa kwabantu ngamanzi;
- ikhono lokuncintisana eliphansi, okungukuthi ngokhula olukhula ngamandla.
Kulandela lokhu ukuthi indlela yokuvikela ephumelela kunazo zonke ukuhlelwa kwendawo yokugcina izilwane zasendle noma isikhumbuzo semvelo.
Isici esifushane
UMarsilea waseGibhithe uyi-fern encane yasemanzini, ubude bayo bufinyelela amasentimitha ayi-10 kuphela. I-rhizome yesitshalo esinjalo yinde futhi incanyana, futhi iba nezimpande kuma-node.
Amaqabunga ahlukaniswa ne-rhizome, okuthiwa yi-frond - ahlala kuma-petioles amade. Ngaphezu kwalokho, ama-sporocarpies ayabonwa (nawo asuka kude ne-rhizome) - ayedwa, kepha atholakala ngemilenze emide.
Amaqabunga mancane futhi ane-obovate, imvamisa enomphetho ongafakwanga. Ngokuqondene nama-sporocarpies, angama-obtuse-quadrangular, ahlanganiswe ne-groove etholakala ku-dorsum noma ku-peduncle, futhi kunamazinyo ambalwa amafushane esisekelweni.
I-Sporulation yenzeka kusuka ngoJulayi kuya kuSepthemba - izinhlamvu zimile ngendlela eyindilinga.
Amaqiniso Athandekayo
IGibhithe iMarsilea ithathwa njengesihlobiso samachibi, ngoba namuhla kunezinhlobonhlobo zesitshalo esinjalo, yingakho kuvame ukusetshenziselwa ukunikeza ukubukeka okungcono emadanyini amancane noma emachibini, kanye nemifudlana eyomile, ephethwe ngasese.
Njengoba isitshalo singatshalwa ezindaweni zasemanzini, sivame ukusetshenziselwa ekhaya ngayo le njongo - ukuhlobisa i-aquarium. Ukutshala kwenzeka ngokwakhiwa kwezinhlamvu zombili ubulili, ezihlangana zibe ama-zygote. Ebusweni bamanzi, abukeka njengamachashazi amancane amhlophe. Ziyaqoqwa futhi zibekwe ukuhluma okulandelayo endaweni enomswakama - kungaba noma isihlabathi. Ukwakhiwa kwesitshalo esisha kuthatha isilinganiso seminyaka eyodwa nengxenye kuya kwemibili.
