CCIMMI: Ho aha holim'a lefa la lilemo tse 50 la lipatlisiso tsa lihlekehleke tsa Channel Islands
California Channel Islands Marine Mammal Initiative (CCIMMI) e thehiloe ka sepheo sa ho ts'ehetsa lithuto tsa baeloji ea batho ba mefuta e tšeletseng ea li-pinnipeds (litau tsa leoatle le liqibi) lihlekehlekeng tsa Channel. Li-pinnipeds ke balebeli ba boiketlo ba maoatle—ba fana ka matšoao a temoso a pele a liphetoho tikolohong e ka amang bophelo ba maoatle le batho hobane kaofela re arolelana mehloli e tšoanang ea maoatle.
CCIMMI e sebetsa e le tšebelisano ea sechaba le ea poraefete pakeng tsa Alaska Fisheries Science Center (AFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA), le The Ocean Foundation (TOF). Maikaelelo a tirisanommogo eno ke go netefatsa tsweletso ya dingwaga tse di fetang 50 tsa dithuto tsa dipatlisiso tsa diamusi kwa California Channel Islands tse di itsiseng ka phetogo ya tlelaemete le mathata a pabalelo ya mawatle kwa Lebopong la Bophirima.
CCIMMI e tšehetsa lenaneo le thehiloeng ho saense la baeloji ea batho ba pinniped California Channel Islands e etelletsoeng pele ke California Current Ecosystems Programme (CCEP) ea Marine Mammal Laboratory ho AFSC. Ka Setsi sa Patlisiso sa San Miguel Island e le motheo oa mantlha oa mosebetsi oa bohlokoa oa masimong, lenaneo le shebana le litlhahlobo tsa bophelo bo botle, bongata, sekhahla sa tsoalo le lefu, le phepelo ea tikoloho ea mefuta e mehlano ea mefuta e mehlano ea liphoofolo tse ruuoang lihlekehlekeng tsa Channel Islands le hore na tsena li angoa ke liphetoho joang. tikoloho. Litšebelisano tse matla tsa mahlale li lebisitse ho boithuto bo bongata bo tsoetseng pele mafapheng a pinniped ecology ea baahi, lefu la seoa la mafu a tšoaetsanoang, le litlamorao tsa bophelo bo botle ba chefo ea tikoloho (ka bobeli ba tlhaho ea domoic acid e tsoang lithunthung tse kotsi tsa algal le litšila tse entsoeng ke batho joalo ka DDT) ho kenyeletsa ho hloleha ha pelehi le mofetše. CCIMMI e thusa litšebelisano tsena tse atlehileng har'a balekane ba mmuso, ba thuto le ba ikemetseng.
Morero oa 1: Lithuto tsa palo ea batho ho boloka palo ea batho ba lilemong tse tsebahalang tsa pinnipeds ho utloisisa litlamorao tsa phetoho ea maemo a leholimo a leoatle ho West Coast pinnipeds.. Ho tšoaea liphoofolo tsa sehlopha se seng le se seng ho lumella litlhahlobo tsa hore na litšokelo tsa tikoloho li ama lihlopha tse fapaneng tsa batho ba lilemo li kae.
Morero oa 2: Ho fokotsa ho tšoasoa ke tau ea leoatleng ea California ka har'a maloanlahla a leoatle. Li-pinnipeds tsa pholoso le ho qhaqholla li thibela ho shoa le ho lumella ho tseba mohloli oa lithōle tse tšoasang.
Morero oa 3: Ho Ngola Mekhahlelo e Tsoelang Pele ea Organochlorine e Silafatsang California Channel Island pinnipeds. Li-tissue biopsies li lumella tlhahlobo ea litlamorao tsa lefa le mehloli e sa tsoa sibolloa ea organochlorine e tsoang metsing a lebopo la California ho baahi ba pinniped.
Morero oa 4: Ho lekola boitšoaro bo hlephileng ba ho batla lijo le tikoloho nakong ea phetoho ea boemo ba leholimo ba maoatle. Tlhahlobo ea mekhoa ea lijo e lumella litekanyetso tsa lijo tse amanang le bophelo ba liphoofolo le ho ngola hore na lijo li fetoha joang ka liphetoho tse susumetsoang ke boemo ba leholimo ho fumaneha ha liphofu.
Morero oa 5: Ho hlahloba ho ata ha mafu a ntseng a hlaha liphoofolong tse anyesang tsa leoatleng lihlekehlekeng tsa Channel. Sampling ea lisele tsa liphoofolo tse tsebahalang li thusa ho utloisisa litlamorao tsa likokoana-hloko tse ncha bophelong ba batho ba pinniped.
Morero oa 6: Khokahano ea ts'ehetso ea lisebelisoa le lichelete bakeng sa Ts'ebetso ea Seteishene sa Lipatlisiso sa San Miguel. Ho fana ka lichelete ka lipalangoang tsa moea tsa lihlopha tsa bafuputsi, lisebelisoa le lisebelisoa le tlhokomelo ea setsi sa lipatlisiso ho thusa ho etsa lipatlisiso tsa masimong tse atlehileng Lihlekehlekeng tsa California Channel.
Ka lilemo tse fetang 130 tsa boiphihlelo bo kopaneng le lipampiri tsa lipatlisiso tse fetang 400 mabitsong a bona, bathehi ba CCIMMI ke baetapele ba tsebahalang lefatšeng ka bophara lefapheng la mahlale a maoatleng a maoatleng. Sehlopha se na le Mookameli oa Lenaneo la CCEP, Robert DeLong, PhD; Frances Gulland, Vet MB, PhD; Mookameli oa ho Hlōla Liphoofolo Setsing sa Mammal sa Marine, Sophie Guarasci, RVT; le monna oa hae, Robert Guarasci, molaoli oa mehleng oa indasteri ea matsete ea nang le tjantjello ea paballo ea maoatle. Sehlopha se sebetsa haufi-ufi le Sharon Melin, PhD, Moetapele oa Hona joale oa Lenaneo la CCEP.
Sepheo sa CCIMMI ke ho ts'ehetsa lenaneo la lipatlisiso tsa baahi ba pinniped. Litšenyehelo tsa bohlokoa tsa ts'ebetso li kenyelletsa litšenyehelo tsa lipalangoang le tsa thepa hammoho le tekanyetso ea ho boloka meaho ea Seteishene sa Lipatlisiso sa San Miguel. Ha re na meputso kapa litšenyehelo tse tsitsitseng, re lebeletse tekanyetso ea selemo e fokolang ea hoo e ka bang $100,000 'me re ikemiselitse ho bokella $500,000 ho lefella lilemo tse hlano tse tlang tsa ts'ebetso.
