Amanzi zigcwele: incazelo kwezinhlobo, ukukhahlamezeka kwendawo, imikhuba yokondla amaqiniso athakazelisayo

Umzuzu crustacean Daphnia wathola amanzi igama zigcwele edume sesibili zifana yakhe eya izinambuzane eziwuhlupho, futhi ikghono intuthuko. Kodwa ngaphandle kwalokho, benza abanalutho abajwayelene ngakho, okungukuthi. Ukuze. Ingabe abameleli amakilasi ahlukene ngokuphelele.

Izici Ezihilelekile Kule Sakhiwo sangaphandle

Daphnia - ilungu edume kakhulu lo mndeni, wayesenza Daphniidae eziningi. Wesikhumba lokhu umzimba bicuspid, lengwegwe amabili komunye umkhawulo umzimba futhi sphericity iso ezithathekayo, okuyinto eliqhutshwa amabhangqa amathathu imisipha oculomotor. Daphnia umzimba okusobala futhi ikuvumela ukuba ubone konke kwenzekani emzimbeni wakhe. Ngisho nokwehla okuncane emisipheni crustacean ubona microscope uma uthanda.

Izici Ezihilelekile Kule Sakhiwo sangekhatsi

Naphezu kobungako nobuningi bayo amancane, umzimba pretty amangalisayo amanzi zigcwele. Incazelo yohlobo waphawula eziningana izici ezithakazelisayo isakhiwo layo langaphakathi. Izinso Daphnia kukhona eduze komlomo, ubuchopho - eduze emphinjeni futhi inhliziyo - ku ngemuva esifubeni. Igazi aphuzi iqukethe amhlophe egazi amaseli - phagocytes, okuyinto ukuvikela umzimba uma crustacean kunesidingo kusuka amagciwane, isikhunta futhi eziphilayo angaphandle.

Amanzi zigcwele usenemigqa ezinhlanu imilenze, kodwa abawona kakhulu ukunyakaza, kodwa isiqondiso ukugeleza kwamanzi emlonyeni wakhe, okuyinto yena ehlungiwe khona izakhi. Breathing ngqo ngokusebenzisa umzimba ihlanganisa.

Distribution okunomsoco nezimo zokuphila

Daphnia zisabalele cishe emhlabeni wonke. Iningi lazo e-sub-ezishisayo futhi ezindaweni ezinezinga lokushisa elithokomele. Empeleni, amanzi zigcwele uhlala amile imizimba amanzi (amachibi, amachibi, imifula nge flow kancane), kanye emachibini. Liphindaphindeke ngokushesha, olukhuni kakhulu, ngakho inombolo yakhe mikhulu. Ingabe ngokuvamile kukholamu amanzi, inyonyoba noma igxume uhamba ngezansi (ngenxa imilenze thoracic).

Daphnia ehlobo ngejubane, kodwa lapho izikhathi ezimbi - nqabela. Ngisho noma echibini lapho ukuthi akuphi, esomile, base bevuswa ngokushesha njengoba ligcwele futhi.

daphnia Iningi - kuyinto herbivorous, kodwa kukhona futhi eziyingozi. Amanzi zigcwele recycles phytoplankton, isikhunta, amagciwane kanye abolile izinsalela izicubu isilwane emva usebenzisa izilwane ezidla ezinye yayo enkulu.

Izinhlobo ezivame kakhulu

Daphnia umndeni kuyinto ngempela eziningi. Kuphela aseYurophu naseNyakatho Melika iyikhaya mayelana 150 zama-ezinamagobolondo. ERussia, njengoba kuyinto evame kakhulu, ezinye zazo - magna, puleks, kukulata, Galeata, Crest. Bonke bahlala imizimba ehlukahlukene amanzi.

Elikhulu kunawo wonke zigcwele amanzi - Daphnia magna. Female it has a ubude 6 mm, ngaphansi iduna kathathu. isikhathi nokuvuthwa we Daphnia osanda kuzalwa ihlala amasonto amabili. Insikazi ibekela amaqanda ayo futhi njalo ngemva kwamasonto amabili (amaqanda mayelana ezintathu kweshumi). Okokuqala, izingane kukhona ezincane ngobukhulu. Kodwa ke ngenkuthalo ezikhulayo. Ukuhlala lolu hlobo cishe izinyanga ezintathu.

Olunye uhlobo ezivamile - kuyinto Daphnia puleks. Abamele kuye kancane ezincane - cishe ezine amamilimitha angu nabesifazane, abesilisa banamathuba aphindwe kabili kancane. Ziyakwazi kwande kakhulu - owendlala amaqanda nanhlanu kwenzeka kanye oyedwa kwabahlanu. Ukuhlala la namazeze amanzi okulula eside - umjikelezo wokuphila kungaba izinyanga unyaka nesigamu. It luyehluka kuye ngokuthi izimo wempilo. Ngokwesibonelo, ukwanda lokushisa kunciphisa ukuphila ngenxa yokuthi kwandisa umzimba ezinamagobolondo.

ukukhiqizwa kabusha

namazeze Water beba semathubeni kakhulu. Zonke daphnia Iqanda-kubekwa sehlukaniswe ihlobo nobusika. Amaqanda esikhathini esithile anezici yabo. Ngokwesibonelo, ebusika wokwakha, basuke embozwe igobolondo aminyene futhi inani labo lincane (mayelana 2 amayunithi), kanye ehlobo kunabaningi. Zonke lezi zici ngenxa zonyaka eside nezimo zokuphila, futhi khona abesilisa. Ehlobo, lapho abantu besilisa sincane kakhulu, amaqanda Daphnia avele futhi yenziwa ngaphandle kokukhulelwa. Amaqanda avundiswa ngabesilisa, imisiwe kanye kuphela ngonyaka - ekwindla. Phakathi zalo ekuphileni umjikelezo zesifazane kungaba abelethe izikhathi 25.

Daphnia ukulinyazwa abantu

Naphezu kweqiniso lokuthi izenze amanzi Daphnia ibizwa ngokuthi, ubuhlobo ukulunywa ke akuhlangene. Noma kunjalo ukulinyazwa abantu kungabangela. Konke allergenic kakhulu. Lokhu kuthiwa kubangelwa yokuthi ngesikhathi nezitshalo eziqhakazayo enobudlova, impova singena emanzini, equkethe Daphnia, futhi labo ithuba profiltrovyvaya kungaba wasithatha kakhulu impova izinhlayiya. Khona-ke, lapho omisiwe ezinamagobolondo, lokhu impova uhlala futhi kungabangela ukusabela kabi komzimba iguliswa emzimbeni womuntu, okuyinto bavame iphutha okwesikhathi namazeze amanzi bite.

izimpawu yokungezwani komzimba ngokuvamile ezivamile - ukuvuvukala conjunctiva esweni (conjunctivitis), amehlo zamanzi, sneezing njalo, ukuminyana acinene futhi nobunzima bokuphefumula.

Ngezinye izikhathi kungase kubonakale sengathi njengoba ukuqubuka emzimbeni, ephelezelwa ukulunywa ezinzima.

Ukusebenzisa Daphnia indoda

Futhi, namazeze kukhona ukudla jikelele inhlanzi aquarium. Kuze kube yimanje, basuke ezifuywa ekhaya.

Kuyinto kudingekile kuphela ukubamba Daphnia emanzini amile, futhi abenzele izimo zokuphila eduze zemvelo. Catching ezinamagobolondo kuwufanele amadamu lapho kukhona okuncane ngokwempilo noma angakutholi nhlobo inhlanzi, njengoba ngokungabi bikho ezidla Daphnia ingaphezu futhi mancane amathuba ukuthi banqotshiwe uma unesifo.

Imigomo zizalela

namazeze Amanzi e aquarium kufanele igcinwe ukuze amanzi ukuthi bahlala kuliphi izwe, ngoba amanzi kampompi akuyona ukudla abakudlayo. Kufanele futhi kufanele unake kukhethwa emaphaketheni lapho ezinamagobolondo izobe iqukethwe. Ngempela, izinto ezifana isibonelo polypropylene, nabo amanzi ezishisa kakhulu zikhipha izinhlayiyana izinto eziyingozi, futhi Daphnia avele afe.

Kuqukethwe izimo aquarium Daphne idinga ukukhanya okuningi. Egumbini okwanele, ayachuma futhi sizale ezinhle. Ngaphezu kwalokho, namazeze awukwazi ukubekezelela abasondelana. Njengoba ande ngokushesha, kudingeka bahlale ukuqinisekisa ukuthi ube nesikhala esanele futhi ngezikhathi uthumele izingxenye amanzi namazeze kwenye aquarium. Lokhu zingachazwa ngezinqubo iqiniso lokuthi ezinamagobolondo kakhulu sensitive yokushodelwa umoya futhi iyafa ngokushesha, izothola kancane.

aquarists Abaningi abafunda ukuzalela daphnia, bathi neze nokudla okumandi kakhulu ngabo - imvubelo wombhaki sika. ukondla kuphela daphnia uqaphe - uma uthele ukudla ngokweqile, amanzi turbid, umoya-mpilo kanye ezinamagobolondo kuyoba okwanele. Ngesikhathi aquarium ngamalitha ezinhlanu isilinganiso esifanele imvubelo, ilingana nekhanda umdlalo. Badinga kuvuse isipuni amanzi kancane uthele aquarium. Futhi ukudla kwezilwanyana ezinamagobolondo kukhona ulwelwe oluhlaza, kuhlanganise Euglena oluhlaza futhi Chlorella.

Kubalulekile futhi ukwazi ukuthi izinga lokushisa ngabo kudingeka ezithile. Lokhu, ngokusho kongoti, kusukela degrees 22 kuya 25. Kungenxa mibandela uphindaphinde namazeze amanzi edamini umzimba amanzi zemvelo.

Kuyadingeka ukuvimbela ukuphehla amanzi futhi ushintshe amanzi (ingxenye yesithathu umthamo isamba) hhayi ngaphansi kwesisodwa noma kabili ngesonto.

Ezinamagobolondo Daphnia ehlungiwe kahle amanzi kusuka amagciwane. Ngakho-ke, aquarists abaningi baye ezifuywa kubo ngoba amanzi - awusebenzi eziqhakaza kanye nasesikhathini eside ihlala ihlanzekile.

Uma uthi nhlá, kungase kubonakale sengathi daphnia ukuzalela ekhaya - lena kukhathaza kakhulu, inqubo isikhathi. Noma kunjalo, lezi ezinamagobolondo - a unyaka wonke ukudla kuhlanzekile kwemvelo ngoba kwezinhlobo eziningi zezinhlanzi (njengoba izingane kanye nabantu abadala).

amanzi Bloch kuyinto kakhulu sensitive ukungcola imvelo ukushintsha ngezithako zawo ionic (i-sodium, magnesium, i-calcium kanjalo kanjalo). Kungenxa yalesi sizathu ukuthi ezinamagobolondo avame ukusetshenziswa ukunquma izinga lamanzi (njengoba amanzi namanzi kusukela amadamu evulekile).
