Amasu Okuqapha Ukuhlukahluka Kwezinhlobo Emahlathini Emvula
Amahlathi emvula aphakathi kwezindawo zemvelo ezicebe kakhulu eMhlabeni. Ngaphakathi kwendawo eyodwa yehlathi, singathola izinkulungwane zezinhlobo zezitshalo, izinambuzane, izinyoni, izilwane ezincelisayo, izilwane eziphila emanzini nasemanzini, isikhunta, kanye nezinambuzane ezincane ezixhumene enhlanganisweni eyinkimbinkimbi yokuphila. Kodwa-ke, lokhu kuceba nakho kusengozini yokushintsha: ukugawulwa kwamahlathi, ukuhlukaniswa kwezindawo zokuhlala, ukuzingela, imililo, ushintsho lwesimo sezulu, kanye nokwethulwa kwezinhlobo ezihlaselayo. Ngakho-ke, ukuqapha ukuhlukahluka kwezinhlobo kubalulekile ekuqondeni izimo zemvelo, ukubona ukwehla kwenani labantu kusenesikhathi, ukuhlola ukusebenza kahle kokongiwa kwemvelo, kanye nokuthuthukisa izinqubomgomo zokuphathwa kwamahlathi eziqhutshwa idatha.
Ukuqapha ukuhlukahluka kwezinhlobo emahlathini emvula kudinga amasu aqondile. Izinselele zibalulekile: indawo enzima, ukumbozwa kwekhava eliminyene, ukufinyelela okulinganiselwe, imvula enkulu, kanye nezinhlobo eziningi zisebusuku noma kunzima ukuzibona. Ngakho-ke, abacwaningi nabaphathi bamahlathi bavame ukuhlanganisa izindlela eziningana ukuze bathole isithombe esiphelele sezinhlobonhlobo zezinto eziphilayo. Lokhu okulandelayo amasu ayinhloko asetshenziswa kakhulu.
1. Ucwaningo Lwezitshalo kanye Nesakhiwo Sendawo
Kumaqembu ezitshalo, indlela ejwayelekile ehlala isebenza kakhulu ukuhlola ngesakhiwo kanye nohlelo lokuhlola. Izakhiwo ezihlala njalo (isib., amamitha angu-20 x 20 noma ezinye izilinganiso ezifanele) zimiswa ezindaweni ezimele. Ngaphakathi kwalezi zakhiwo, abacwaningi bathola izinhlobo zezihlahla, balinganise ububanzi ekuphakameni kwesifuba (i-DBH), ukuphakama kwesihlahla, futhi baqophe ukuvuselelwa kabusha (izithombo nezithombo). Ngokusungula izindawo ezihlala njalo, izinguquko ekwakhekeni kwezinhlobo zingaqashwa unyaka nonyaka, kufaka phakathi ukuguquguquka kokufa kwezihlahla nokukhula kwazo.
Izindlela zokubhala, izindlela eziqondile ezilandelwa abacwaningi, zingasetshenziswa ukuqopha izinhlobo zezitshalo noma izimpawu zezilwane zasendle. Le ndlela ayibizi kakhulu futhi ilula, kodwa incike emakhonweni okuhlonza kanye nokungaguquguquki kwababukeli. Inselele enkulu kakhulu ukwakheka kwezitshalo zasehlathini, okuvame ukudinga izazi zezitshalo kanye nezitshalo ukuze kuqinisekiswe.
2. Isicupho Sekhamera
Izicupho zamakhamera sezibe yindinganiso yesimanje yokuqapha izilwane ezincelisayo zasemhlabeni nezinyoni okunzima ukuzibona ngqo. Amakhamera afakwa ezindleleni zezilwane, eduze kwemithombo yamanzi, noma ezindaweni lapho kubonakala khona imikhondo (izinyathelo, amaconsi, izimpawu zezinzipho). Amakhamera athatha izithombe noma aqophe ividiyo lapho izinzwa zawo zokunyakaza zivulwa.
Izinzuzo zezicupho zamakhamera zifaka phakathi ukusebenza kwamahora angama-24, ukuphazamiseka okuncane kwabantu, kanye nokutholakala okuphumelelayo kwezilwane ezinamahloni noma zasebusuku njengezilwane zasendle, ama-pangolin, nama-tapir. Idatha etholakala ingasetshenziswa ukubala izinkomba zobuningi obuhlobene, amaphethini omsebenzi wansuku zonke, kanye nokulinganisa ubuningi babantu kusetshenziswa izindlela ezithile zezibalo (isb., ukubamba kabusha izinhlobo ezinephethini yomzimba ehlukile). Kodwa-ke, le ndlela idinga imishini ebizayo, amabhethri, inkumbulo, kanye namasu okubeka ukuze kuqinisekiswe ukuqapha okungachemile.
3. Ukuqapha I-Acoustic (Bioacoustics)
Izinhlobo eziningi zehlathi lemvula, njengezinyoni, amaxoxo, nezinambuzane, kulula ukuzizwa kunokuzibona. Ngakho-ke, amayunithi okuqopha azimele (ama-ARU) aya ngokuya evame kakhulu. Lawa madivayisi abekwa ezindaweni ezithile ukuze aqophe imisindo ngesheduli emisiwe (isibonelo, imizuzu embalwa njalo ngehora) noma ngokuqhubekayo.
Ukuqoshwa kungahlaziywa ukuze kutholakale ukuthi kukhona izinhlobo ezithile ngokusebenzisa imisindo ehlukile, kulinganiswe izinkomba zokuhlukahluka kwe-acoustic, noma kuqashwe izinguquko zomphakathi ngokuhamba kwesikhathi. I-Bioacoustics iwusizo kakhulu ezindaweni ezinokufinyelela okulinganiselwe ngoba amadivayisi angashiywa eqopha izinsuku noma amasonto. Izinselele zifaka phakathi isidingo sesofthiwe yokuhlaziya, ukuhlelwa kwedatha okukhulu, kanye nokwenzeka komsindo wemvelo njengemvula enkulu noma imifula egelezayo ukufihla imisindo yezilwane.
4. Ucwaningo Olubonakalayo kanye Nenani Lamaphuzu Ezinyoni
Ezinyonini, inqubo yokubala amaphuzu isalokhu iyindlela eyinhloko. Abaqaphi bama endaweni ethile isikhathi esijwayelekile (isb., imizuzu eyi-10) bese beqopha zonke izinyoni ezibonwe noma ezizwiwe ngaphakathi kwerediyasi ethile. Ukubala okuphindaphindiwe ezindaweni eziningi kanye nezikhathi ezahlukene kuvumela ukuqhathanisa phakathi kwezindawo kanye nemikhuba yesikhathi eside.
Le ndlela iyasebenza futhi ayibizi kakhulu, kodwa incike kakhulu ekhonweni lomqaphi lokubona imisindo yezinyoni kanye nokuzibona kwazo. Ukwehluka kwesimo sezulu, isikhathi sosuku, kanye nesizini yokuzala nakho kuthinta ubukhali bokukhala kwezinyoni, ngakho-ke ukwakheka kokuhlola kumele kucabangele isimiso esihambisanayo.
5. Ukusampula Izinambuzane: Ugibe Olune-Malaise, Ugibe Olulula, kanye Nogibe Lwe-Pitfall
Izinambuzane zivame ukuba yingxenye enkulu kunazo zonke yezinhlobo zezinto eziphilayo zasehlathini, kodwa futhi ziyinselele kakhulu ukuziqapha. Ezinye izingibe ezivamile zifaka:
– Ugibe lwe-malaise lokubamba izinambuzane ezindizayo njengeDiptera neHymenoptera.
– Isicupho esilula sezinambuzane zasebusuku ezikhangwa ukukhanya, njengezinundu.
– Izicupho zemigodi ziyizitsha ezisemhlabathini zokubamba izilwane ezihambayo njengezinambuzane zasemhlabathini kanye nezicabucabu.
Ukuthatha amasampula ezinambuzane ngokuvamile kudinga ukuhlonza ilabhorethri, ngokuvamile ngosizo lokuhlaziywa kwe-DNA, njengoba izinhlobo eziningi kunzima ukuzihlukanisa ngokwesimo sazo. Noma kunjalo, idatha yezinambuzane ibalulekile ngoba zisabela ngokushesha ezinguqukweni zendawo yokuhlala futhi ngokuvamile ziyizinkomba zempilo yesistimu.
6. I-DNA Yemvelo (i-eDNA) kanye ne-Metabarcoding
Enye yezinto zakamuva ezithuthukisiwe ukusetshenziswa kwe-DNA yemvelo (i-eDNA). Izinto eziphilayo zishiya iminonjana yezakhi zofuzo ngesikhumba, indle, i-mucus, noma imfucumfucu yomzimba engena emanzini, enhlabathini, noma emoyeni. Ngokuthatha amasampula emanzini omfula, enhlabathini, noma emaqabunga, abacwaningi bangathola ukuba khona kwezinhlobo eziningi ngesikhathi esisodwa ngokusebenzisa amasu e-metabarcoding.
Inzuzo yale ndlela yikhono layo lokubona izinhlobo ezingavamile nezinzima ukuzibona futhi inikeze umbono osheshayo womphakathi. Kodwa-ke, i-eDNA idinga izindawo zelebhu, izinqubo eziqinile zokuvimbela ukungcola, kanye nedathabheyisi yezakhi zofuzo eyanele. Ukuchazwa kudinga nokuqapha: ukutholakala kwe-DNA akusho ukuthi kunabantu abaningi bendawo; i-DNA kungenzeka ukuthi yayithwalwe yimisinga yamanzi evela kwezinye izindawo.
7. Ukuzwa Okukude Nama-Drones
Nakuba amasathelayithi nama-drone engakwazi "ukuzibona" ngqo izinhlobo, lobu buchwepheshe bubalulekile ekuqapheni izimo zendawo yokuhlala, ezixhumene kakhulu nokuhlukahluka kwezinto eziphilayo. Idatha yokubona kude isiza ekuhloleni ukumbozwa komhlaba, ushintsho lwekhava, ukuqhekeka, indawo eshisiwe, kanye nenkomba yezitshalo. Ama-drone anganikeza izithombe ezinesinqumo esiphezulu ukuze kudwetshwe izikhala zamahlathi, imihubhe yezilwane zasendle, noma indawo yezihlahla ezithela izithelo ezibalulekile kuma-primates.
Uma kuhlanganiswa nedatha yasensimini (izicupho zekhamera, amagrafu ezimila, noma imisindo), ukuzwa kude kuqinisa ukuhlaziywa: singaxhumanisa izinguquko emiphakathini yezinhlobo nezinguquko esakhiweni sendawo ngokwendawo nangesikhathi.
8. Ukuzibandakanya Komphakathi kanye Nesayensi Yezakhamuzi
Ezindaweni eziningi zehlathi lemvula, imiphakathi yasendaweni yiyo evame ukuba semhlabathini. Ukuzibandakanya ekuqapheni—ngokusebenzisa ukuqapha okusekelwe emphakathini, ukuqopha ukuhlangana kwezilwane zasendle, noma ukubika ukuzingela ngokungemthetho—kungandisa ukumbozwa kwedatha futhi kuqinise ukuvikelwa kwendawo. Le ndlela idinga ukuqeqeshwa, iziqondiso ezicacile zokuhlonza, kanye nezindlela zokuqinisekisa idatha ukuqinisekisa imiphumela ethembekile.
9. Izimiso Zokuklama Okuhle Kokuqapha
Noma yiluphi uhlelo lunamandla kakhulu uma lusekelwa umklamo wokuhlola ofanele. Ezinye izimiso ezibalulekile zifaka: ukunquma izindawo zamasampula ezimele, ubude bokubuka obujwayelekile kanye nemvamisa, amakhophi, ukuqopha i-metadata (isimo sezulu, isikhathi, izixhumanisi), kanye nokugcinwa kwedatha okusebenzayo. Ngaphezu kwalokho, kubalulekile ukuhlukanisa phakathi kwezinhloso zokuqapha: kungakhathaliseki ukuthi kuyimpahla yokuqala, ukutholwa kwezinhlobo ezingavamile, ukuhlolwa komthelela wokuphazamiseka, noma ukuqapha imikhuba yesikhathi eside.
I-Penutup
Ukuqapha ukuhlukahluka kwezinhlobo emahlathini emvula akukwazi ukuthembela endleleni eyodwa. Izizalo zezitshalo zinikeza ukuqonda ngesakhiwo sezitshalo kanye nokwakheka kwazo, izicupho zekhamera zivelele ezincelisayo zasemhlabeni, ama-bioacoustics ayasebenza ekukhulumeni kwezilwane, izicupho zezinambuzane zithuthukisa ukuqonda kwamaqembu ahlukahlukene kakhulu, i-eDNA inikeza ukutholwa okusheshayo kuwo wonke ama-taxa, futhi ukuzwa kude kukhanyisa ushintsho lwendawo yokuhlala esikalini sendawo. Ngokuhlanganisa lawa masu, singakha izinhlelo zokuqapha ezinembile, ezisebenzayo nezisebenzayo zemizamo yokulondoloza.
Ekugcineni, ukuqapha kungaphezu nje kokuzivocavoca kwesayensi; kuyisisekelo sokugcina amahlathi emvula ephila. Idatha enhle isisiza ukuthi sibone izimpawu zengozi kusenesikhathi, sihlole ukusebenza kahle kwezinyathelo zokuvikela, futhi sakhe izenzo zokulondolozwa eziqondiwe ukuze kuqhutshekwe nokusimama kwezinhlobonhlobo zezinto eziphilayo.
