Umthelela Wokufudumala Komhlaba Ezinhlotsheni Ezihlala Zikhona
Ukufudumala komhlaba, ukushisa kwesikhathi eside kwesimiso sezulu soMhlaba ngenxa yemisebenzi yabantu, kunemiphumela ebanzi ezinhlobonhlobo zezinto eziphilayo emhlabeni wethu. Omunye wemiphumela ebaluleke kakhulu ubonakala ezinhlotsheni zezilwane ezihlala endaweni ethile—lezo zitshalo nezilwane ezihlala endaweni ethile. Ngenxa yokuthi izinhlobo zezilwane ezihlala endaweni ethile ziye zavela ukuze zichume ezindaweni zazo zokuhlala ezithile, zisengozini enkulu yokushintsha kwesimo sezulu. Lesi sihloko sizohlola izindlela ezahlukene ukufudumala komhlaba okuthinta ngazo izinhlobo zezilwane ezihlala endaweni ethile, okuhlanganisa ukuphazamiseka kwemvelo, ukulahlekelwa yindawo yokuhlala, kanye nezinsongo zokuqothulwa, kuyilapho sigcizelela ukuphuthuma kwemizamo yokulondolozwa kwemvelo.
1. Ukuguqulwa Nokulahlekelwa Yindawo Yokuhlala
Omunye wemiphumela eshesha kakhulu nejulile yokufudumala komhlaba ezinhlotsheni ezihlala khona yizinguquko kanye nokulahleka kwendawo yokuhlala. Njengoba amazinga okushisa enyuka, izindawo eziningi zibhekana nezinguquko ezimweni zezulu, amazinga emvula, kanye nokufaneleka kwesimo sezulu jikelele. Isibonelo, amahlathi amafu aseCentral naseNingizimu Melika, aphethe izinhlobo eziningi zezinhlobo ezihlala khona, azwela kakhulu ekushintsheni kwezinga lokushisa kanye nokwehla kokumbozwa kwamafu. Njengoba la mahlathi amafu oma, izinhlobo ezincike emswakama oqhubekayo, njengezilwane ezihlala emanzini nasemanzini nama-orchid, zibhekene nenani labantu elinciphayo.
Izifunda zasePolar, ikhaya lezinhlobo ezifana ne-Antarctic krill namabhere asePolar, zibhekana nokuncibilika kweqhwa okusheshayo ngenxa yokushisa okushisa. Lezi zinhlobo, ezithembele ezindaweni zokuhlala ezimbozwe yiqhwa ukuze zizalele, zizingele futhi ziphephe, zibona izindawo zokuhlala zincipha, okuholela ekunciphiseni kobuningi babantu kanye nempilo yazo engcupheni.
2. Ukuphazamiseka Kokuxhumana Kwemvelo
Ukufudumala komhlaba akuthonyi nje kuphela uhlobo ngalunye kodwa futhi nenethiwekhi eyinkimbinkimbi yokuxhumana kwemvelo. Izinhlobo eziningi ezitholakala ezindaweni ezithile zihilelekile ebuhlotsheni obukhethekile bokubambisana—lapho izinhlobo zithembele komunye nomunye ukuze ziphile. Isibonelo, izitshalo ezithile zithembele kuphela kubathuthi bempova abathile. ENingizimu-ntshonalanga ye-United States, umuthi kaJoshua unobuhlobo bokubambisana ne-Yucca moth ukuze kuthuthwe impova. Ukuphakama kwamazinga okushisa kanye nokushintsha kwezikhathi zokuqhakaza kungaphazamisa lokhu kusebenzisana, okuholela ekuhlulekeni kothuthwe impova kanye nokwehla kwenani labantu kuzo zombili izinhlobo.
Ngokufanayo, ukushintsha kwesimo sezulu kungabangela ukungalingani emizimbeni yezilwane ezidla ezinye izilwane. Uma uhlobo lwezilwane ezidla ezinye izilwane lushintsha indawo yalo noma lushintsha indlela eziziphatha ngayo ngenxa yokushintsha kwamazinga okushisa, izilwane ezidla ezinye izilwane zingase zingakwazi ukuzivumelanisa ngokushesha, okuholela ekuncipheni noma ngisho nasekufeni kwezilwane endaweni.
3. Izinguquko Ze-Phenological
I-Phenology, isifundo sezehlakalo zemvelo ezijikelezayo njengokuqhakaza, ukuzalanisa, kanye nokufuduka, nayo ithintwa ukufudumala komhlaba. Izinhlobo zezilwane ezihlala endaweni ethile zivame ukuvumelanisa imijikelezo yazo yokuphila nezimpawu ezithile zesizini. Njengoba ukufudumala komhlaba kubangela amaphethini ezulu angaguquki kanye nezinkathi ezishintshashintshayo, lezi zilinganiso azibe zisathembekile.
Isibonelo, ezindaweni ezinezintaba, izinhlobo eziningi zezitshalo ezitholakala kalula zithembele ezibonelweni eziqondile ezivela ekuncibilikeni kweqhwa ukuze ziqale ukuhluma. Njengoba ama-snowpack encibilika kusenesikhathi ngenxa yokushisa okunyukayo, izitshalo zingase zihlume kusenesikhathi, zibhekane nezingozi ezengeziwe zokulimala kwesithwathwa noma ukucindezeleka kwamanzi. Ngokufanayo, ezinye izinhlobo zezinyoni zingase zifuduke kusenesikhathi ngenxa yokushisa okushisa, zibe sengozini yokufika ngaphambi kokuba imithombo yazo yokudla eyinhloko itholakale ezindaweni zazo zokuzalela.
4. Ukwanda Kokusengozini Yezifo Nezinhlobo Ezihlaselayo
Ukushintsha kwesimo sezulu kungandisa kakhulu ubungozi bezinhlobo ezihlala khona ezifweni nasezinhlotsheni ezihlaselayo. Amazinga okushisa afudumele angandisa ububanzi bezifo ezibangelwa amagciwane kanye nezinambuzane, okuveza izinhlobo ezihlala khona ezinsongweni ezintsha zempilo. Isikhunta se-amphibian chytrid, esiqede inani lamaxoxo emhlabeni wonke, sichuma ezimweni ezifudumele nezimanzi, okubeka izilwane ezihlala khona engcupheni enkulu.
Ngaphezu kwalokho, ukushintsha kwezimo zezulu kungasiza ekuhlaselweni kwezinhlobo ezingezona ezomdabu ezizivumelanisa kangcono nezimo ezintsha, zincintisane noma zidle izinhlobo ezitholakala endaweni ethile. Isibonelo, eziQhingini zaseGalápagos, ukwethulwa kwezinhlobo zezitshalo ezihlaselayo, ezichuma ngaphansi kwezimo zezulu ezishintshile, kusongela izitshalo zemvelo ngokulawula izinsiza ezifana nokukhanya, isikhala, kanye nezakhamzimba.
5. Izinsongo Zokuqothulwa
Umphumela wokulahlekelwa yindawo yokuhlala, ukuphazamiseka kokuxhumana, izinguquko ze-phenological, ukuthambekela kwezifo, kanye nezinhlobo ezihlaselayo ekugcineni kungaholela ekutheni izinhlobo ezihlala endaweni eyodwa ziphele. Lezi zinhlobo zivame ukuba nobukhulu obuncane bomphakathi kanye nezindawo ezilinganiselwe, okwenza zingabi namandla okumelana nezinguquko ezisheshayo zemvelo. I-Pika, isilwane esincane esincelisayo esihlala ezindaweni ezibandayo zezintaba, ibhekene nokwehla komphakathi njengoba amazinga okushisa anciphisa indawo yayo efanele yokuhlala ezintabeni. Njengoba ingakwazi ukuthuthela ezindaweni ezipholile, izinhlobo eziningi ze-Pika zibhekene nokuphela okuseduze.
Izindawo zemvelo zaseziqhingini zithambekele kakhulu ekulahlekelweni yizinhlobo zazo ezihlala khona. Ukwenyuka kwezinga lolwandle okubangelwa yisimo sezulu kusongela izindawo zokuhlala zezinhlobo ezihlala khona njengeTuamotu Kingfisher eFrench Polynesia. Njengoba kunezindawo ezilinganiselwe eziqhingini ezilodwa noma amaqoqo eziqhingi, noma yikuphi ukuguqulwa okukhulu kwendawo yokuhlala kungaqeda kalula zonke izinhlobo.
6. Imizamo yokonga
Ukuba sengozini kwezinhlobo zezilwane ezitholakala endaweni ethile ekushiseni komhlaba kugcizelela isidingo esiphuthumayo semizamo yokulondolozwa eqondiwe. Amasu okulondolozwa kumele abhekane nezinsongo ezisheshayo kanye nokusimama kwesikhathi eside. Ukudala izindawo ezivikelwe ezilondoloza izindawo zokuhlala ezibalulekile kanye nokusungula imizila yezemvelo kungasiza izinhlobo zezilwane ukuba zivumelane nezimo zezulu ezishintshayo ngokuhlinzeka ngezindlela zokufuduka ziye ezindaweni ezifanele kakhudlwana.
Imizamo yokulwa nezinhlobo ezihlaselayo kanye nokulawula izifo nayo ibaluleke kakhulu. Lokhu kungabandakanya izinyathelo ezifana nokusetha izinqubo zokuphepha kwezinto eziphilayo ukuvimbela ukungeniswa kwamagciwane kanye nezinhlobo ezingezona ezomdabu kanye nokwenza ucwaningo lokuthuthukisa izinhlobo zezitshalo nezilwane ezingamelani nezifo.
Amaphrojekthi okuvuselela nawo adlala indima ebalulekile ekuvuseleleni izindawo zemvelo ezonakele. Ukuvuselela amahlathi ezindaweni ezinezinhlobo zemvelo, ukubuyisela izindawo ezimanzi, nokubuyisela izinhlobo zezitshalo eziyinhloko kungathuthukisa ukuqina kwezindawo zemvelo ekushintsheni kwesimo sezulu. Ngaphezu kwalokho, izinhlelo zokuzalanisa ezivalelwe kanye nezinhlelo zokugcina imbewu zinganikeza isivikelo ekushabalaleni, zilondoloze ukuhlukahluka kwezakhi zofuzo futhi zivumele ukubuyiselwa kwezitshalo esikhathini esizayo.
Isiphetho
Ukufudumala komhlaba kubeka usongo olunezinhlangothi eziningi ezinhlotsheni ezihlala khona, okubeka izinselele ezinkulu zemvelo, zokuziphatha, kanye nezomzimba. Njengoba iplanethi iqhubeka nokufudumala, ukusinda kwalezi zinhlobo ezivumelaniswe ngendlela ehlukile kuzoncika emizamweni yethu yokubambisana yokunciphisa ukuguquka kwesimo sezulu nokusebenzisa amasu okulondoloza asebenzayo. Ukubhekana nezidingo ezithile zezinhlobo ezihlala khona akubalulekile nje kuphela ekusindeni kwazo kodwa futhi kubalulekile ekulondolozeni ukwakheka okuyinkimbinkimbi nokuhlukahlukene kokuphila eMhlabeni. Ngokubeka phambili ukuvikelwa kwezinhlobo ezihlala khona, siqinisekisa impilo nokuzinza kwezindawo zemvelo zomhlaba wonke, okuzuzisa zonke izinhlobo zokuphila, okuhlanganisa nezethu.
