Ejection Mass of iminenga phezu komhlaba. Kutheni ulahle kude iminenga elunxwemeni?

Umnenga efile elunxwemeni - njengomboniso buhlungu, kwanyanzeleka zama ukuqonda unobangela wokufa nje isilwanyana enkulu kunye ezintle. Kwaye ukuba akukho whale kodwa ezimbini, ezintlanu, ishumi?

Kutheni yiminenga ukuba beaching?

wokunciphisa Mass of iminenga elunxwemeni kukho iimfihlelo yeengxaki obangel 'umdla zendalo, apho izazinzulu ezininzi besonwaya iintloko zabo namhlanje. emehlweni ebuhlungu Izidumbu zezilwanyana esikhulu imeko engaqhelekanga kuba kubo ingqiqo ehexisayo nofefe. Yintoni eyenza abemi eziyintloko babeziindleko ocean ukuphelisa ubomi elunxwemeni ezinentlabathi bafe phantsi laligqatse ubhobhoyi ilanga? Kutheni ulahle kude iminenga elunxwemeni?

Ngokomzekelo, ngoFebruwari 2015 kunxweme ezikhutshwayo New Zealand ngayo dolphins 200. Ngokutsho izazinzulu, into mass onjalo anayenza iminyaka engaphezu kwama-10. Nangona kwemizamo emihle abahlanguli, ikhulu kuphela abantu abasindayo. Abanye wafa phantsi ubunzima bayo kwaye ngenxa yokunqongophala kwamanzi. Nangona uninzi ezikhutshwayo kwenzeka iqela iminenga, uninzi phakathi kweentlobo ezinzulu-elwandle.

Ungcoliseko Sound olwandle

isibhakabhaka olukhulu lwamanzi ezaliswe ezahlukeneyo izandi, uninzi lwazo ke imvelaphi yendalo. Iya isanda, kulinganiswa wolwandle ubomi kuwuhlambela umntu wenza ingxolo (ukusuka lweenqanawa ezintywilayo injini, imigodi, uvavanyo yomkhosi kunye neentlanzi ubambisa). Ngenxa yoko, phantsi kwempembelelo dolphins sonar neminenga ulahlekelwa ezindlebeni zabo phantse-40%.

Ntoni ubuthulu (a isixhobo obhityileyo, ukukwazi ukwahlula ukungalingani incinane emanzini) ukuba isilwanyana kuxhomekeke kubuchule ukuva ubomi bakhe? traps sound kwamanzi disorient ezi zilwanyana umzimba ngamanzi, enkqonkqoza ukuba indlela njengesiqhelo, kutheni iminenga kunye dolphins, ezilahlekileyo emajukujukwini, ukudada emanzini.

ukunyukela ngokukhawuleza kakhulu kumphezulu inegalelo sibubona ukugula iefa decompression, apho ngenxa zokucutha esikhawulezileyo-nitrogen amaqamza yande egazini kunye umonakalo izibilini imithambo yegazi. Le nkkolelo kuqinisekiswa zizazinzulu ukufumana iimpawu isifo kwi yotyando kwezilwanyana ezifileyo. amaqamza nitrogen equlethwe igazi iminenga, phantsi iingqikelelo izazinzulu benokuba nempembelelo ingxolo elikhulu ngqo ukusuka iinjini zonke ii nkwili kunye neziqhushumbisi. Phantsi isenzo kwamaza isandi igwebu ukwanda ngokukhawuleza kwaye yekontraka ingathintela imithambo yegazi, umonakalo izicwili kunokwenzakalisa luvo.

Isizathu sokuba ukufa ubunzima iminenga - ukuzilolonga zomkhosi?

kuqhuma Strong, ukongeza izitya uphawu uphazamise amalungu zezilwanyana. Le meko (nokopha wemiphunga yophela ngamalungu angaphakathi) abaphandi iqatshelwe kuphando berhaxwa ngexesha okanye emva umthambo yamajoni neminenga kunye namahlengesi. Ngokomzekelo, ngowe-1989 ngexesha imithambo aselwandle kufuphi elikwiiCanary Islands kunxweme ezikhutshwa 24 womnenga. Kutheni ulahle kude iminenga elunxwemeni? Kungenzeka, isizathu waba ingxolo olungaphezu kwamanzi, ngokoqobo amnqande ubomi emanzini. Lweenqanawa ezintywilayo umonakalo owenziwe eziphila elwandle, safunda ngenyameko yonke baseMelika, kuba sohlala kweli lizwe kwisakhiwo zomkhosi ufakwa ukuya uxinzelelo loluntu kakhulu.

strandings Whale kwenzeka naphambi yimbonakalo kwemvelo ngabantu kwaye ukuvela ii nkwili. Ngaloo mihla owayenokugqiba ekubeni lo msebenzi Ocean abahlala? Ngowe-1950, elunxwemeni kwisiqithi ezikhutshwayo Stronsay 64 iminenga, emva kweminyaka emi-5 apha babulawa 66 dolphins. Yintoni eyenza izilwanyana ukukhetha le ndlela yokufa? Kutheni ulahle kude iminenga elunxwemeni?

Ukungaphumeleli kwamabala magnetic?

Ngokutsho kwithiyori Margaret Klinovsky ngonyaka uthuthe iminenga emanzini olufudumeleyo okuchumisa kokuba inkomo izele, emva koko izilwanyana zaselwandle phinda. kulo mzila ixhomekeke ikakhulu owahluke ngokwemvelo, zona uhlobo kwemihlaba. Xa Ekuhlanganeni kweendlela, ukuhla nokunyuka inkulu kwezi nkalo iminenga eziphelelwa isini sabo kwaye ukudada emanzini. Kuyaphawuleka ukuba iminenga ukuzibulala mass advantageously kwenzeka ngokukhawuleza emva ezithile, ukutyhefa imigca ngemagnethi.

Ngokutsho kuguqulelo mnye, iminenga ukuba beaching ngenxa utshintsho phantsi kweemeko zemozulu. Ocean imisinga evela Antarctic amanzi abandayo siyabanyanzela iminenga ukuhamba emanzini nzulu ngenjongo shushu. E Australia, ukukhutshwa sabhalwa iminenga phezu 80 oluphahlwe ngokoqobo kunye nemizimba lommandla yakhe yonxweme sekhilomitha ezintlanu. Wakwazi ukuba asindise abantu-25 kuphela. Kutheni ulahle kude iminenga elunxwemeni? Yintoni unobangela ngokuzibulala abaninzi? Mhlawumbi ukulahlekelwa orientation, nto leyo enokuphazamisa isimo sezulu? Xa imozulu esindayo umoya gusty onamandla kwesidingo storm zingenzeka okanye babizwa ngokuba amanzi kwakhula. Animal uqubha ukusondela kakhulu nomhlaba, apho unako uhlale ngaphandle ulungelelwaniso ngendlela efanelekileyo xa amanzi besishiya.

Self-ummiselo inani - omnye ngaphezulu Inkolelo iminenga komoya mass elunxwemeni. Version has indawo khona, nangona abemi iminenga kwindalo ezingathanga abakhulu makakubuze oko ukusika.

Unobangela wokufa iminenga - ungcoliseko kwezilwandle?

Njengoko unobangela ukukhutshwa ubunzima iminenga lolwandle kuqwalaselwa ungcoliseko ezilwandle, ngokuthe ngcembe ajike abe yokulahla enkulu enkulu. olwenzeka othile inkunkuma, isahlulo sesihlanu babo ezikhutshwayo mveliso neoli inkunkuma iwela kunxweme Hawaii. Ngu lingu- Rudi Patch ebekwe kwi-Pacific Ocean, yendebe kunye United States zwekazi. Ngokuqhelekileyo, yokulahla elikhulu enjalo, apho ubunzima ngaphezu kwezigidi 100 iitoni, iba nefuthe elibi iintlanzi. Nangona ezi zilwanyana kunye nentlanzi azikho ngokungafaniyo kubo siphefumle umoya, kungekhona iyasuleleka zomongomoya onyibilikisiweyo ngendlela zolwelo medium, umonakalo evela lweetiphu ezinjalo, ukuze kubangelwa Unxunguphalo ebetha slicks ioli.

Mhlawumbi into lwezentlalo-psychological?

hypothesis izangoma kwakhona abeke phambili njengomnye oonobangela kweminenga ejection mass elunxwemeni. Nama dolphins zizilwanyana zentlalo, ngokuxhomekeke yempembelelo yinkokeli. Ukuba yokugqibela ilahlekileyo zoLwazi isithuba kwaye ibonisa njengomhlambi emanzini, izilwanyana, nangona sisesichengeni sokufa, basaqhubekeka ukulandela yena.

Kuthatha indawo kubukho ingcamango ezosulelayo ezibulalayo ze iintlanzi, leyo ngoku ingqalelo eyodwa inikwa izazinzulu ehlabathini jikelele. Ezinye iintsholongwane bathelela ezanyisayo, ibe nefuthe elibi izilwanyana yokuncedisa ukuva, ebangela izifo ezifana meningitis kwaye kobuchopho, abangele ukusilela kwinkqubo amaza. Ubuntwana zoLwazi isithuba kwikhithi (iifoto inokubonwa kwinqaku) iqala ziliminxe, ngoko beaching ngokwayo ukuba lula ukuphefumla. Ukubuyela element lwabo ziya mandundu kuphela le meko. Kuqala wacinga ukuba iminenga nga kujoliswe yintsholongwane. Enyanisweni, ukuba babe naso zamanzi elwandle - ukutya killer.

Ngengozi ukubetha elunxwemeni, isilwanyana anganika iimpawu lokubandezelwa komnye, ngubani nangoko sukela awayihlangula, kwaye ihlwempu eyele kumgibe ofanayo ucela uncedo.
