Utshintsho lwemozulu luchaphazela amahlathi eMeditera

amakhonkco

Iindidi ezahlukeneyo zeziphumo ezibangela imo iyatshintsha Zenza ukuba izinto ezininzi eziphilayo zibe semngciphekweni kwaye ziqale ukonakala, ezinje ngeeConifers.

Phakathi kweziphumo ezibonakala kakhulu kukunyuka kwexesha kunye nokuhamba kwexesha lembalela, izikhukula, njl. Ukunyuka kwamaqondo obushushu kunye nexesha elide lembalela kusongela amanye amahlathi e-Iberia.

Uphando ngothando lweeConifers

Olu phando malunga nefuthe lembalela kumahlathi e-coniferous lwenziwe iYunivesithi yasePablo de Olavide (UPO), iSeville, iZiko lasePyrenean leEcology (CSIC) kunye neDyunivesithi yaseBarcelona. Ukugqibezela uphando, lo msebenzi ubenentsebenziswano yeeDyunivesithi zeComplutense zaseMadrid naseColumbia (e-USA) kunye neSwitzerland Federal Institute for Forest, Snow and Landscape Research (WSL). Ukongeza, umsebenzi upapashiwe kwijenali ye-Global Change Biology.

Inkokheli yomsebenzi ibikhona URaúl Sánchez Salguero, emva kophando kwi-UPO nakwi-IPE-CSIC. Uphononongo lujolise kumngcipheko osongela amahlathi ngasemazantsi. Ukwanda kwamaqondo obushushu abangelwa kukutshintsha kwemozulu kunye nexesha elide kunye nokuhamba rhoqo kwembalela kusongela iintlobo ezinje nge ipine yaseScotsUPinus sylvestris, umkhonto (enzonzobileni alba) kunye nompayini omnyama (UPinus uncinata).

Ukuxela kwangaphambili iimpembelelo kunye notshintsho olwenzeka kwezi ntlobo, sisebenze neemodeli zezibalo ezisekwe kwimpembelelo yemozulu kubukhulu bamaringi okukhula konyaka afundwe yi-dendrochronology.

Amahlathi aseMeditera asesichengeni

Ngokufunda la makhonkco okukhula kube nakho ukuvavanya ukuba sesichengeni kwamahlathi ngaphezulu kwemozulu ebanzi kunye ne-biogeographic gradients. Ukuqikelela ukuba semngciphekweni kwemithi, ulungelelwaniso oluqwalaselweyo lwamahlathi kutshintsho lwemozulu oluqwalaselwe kwisiqingatha sesibini senkulungwane yama-XNUMX kuthathelwe ingqalelo. Baye ke bacacisa ukuvela okwethutyana kokukhula kwala mahlathi phantsi kweemeko zemozulu ezahlukeneyo, ezifunyenwe ngokusekwe kwimeko zentlalo noqoqosho eziqikelela ukukhutshwa kwegesi yendlu eluhlaza ngekhulu lama-XNUMX.

Abaphandi bagqibe kwelokuba amahlathi eMeditera asemngciphekweni wempembelelo zotshintsho lwemozulu, ngakumbi imbalela. Nangona iimpendulo zale nkqubo yezinto eziphilayo zinamazinga amakhulu okungaqiniseki phambi kweemeko zemozulu eziye zaxelwa kwangaphambili ukuba iimeko zokukhutshwa kwegesi yendlu eluhlaza ziqhubeka ngoluhlobo.

Kule ecosystems kukho iindidi ezinento engaphezu koku ubhetyebhetye kunye neplastiki kutshintsho lobushushu kunye nokumelana nembalela.

“Ukuvavanya nokuchaza imingcipheko yokuba sesichengeni yokutshintsha kwemozulu kubalulekile ukumisela amanyathelo okulawula amahlathi anokuthintela ezi ziphumo, ngakumbi kwezona ndawo zisasazekayo zokusasaza, kunye nokuchonga abo bantu bayinyamezelayo inguquko yemozulu. ukumisela amanyathelo olondolozo ”abonise uRaúl Sánchez-Salguero noJuan Linares.

Isifundo seCarbon

Kubalulekile ukuvavanya utshintsho kwimijikelo yekhabhoni kuhlobo lwezinto eziphilayo zeMediteranjengamahlathi afaka isixa esikhulu sekhabhon diokside kwifotosinthesisi. Le CO2 igcinwa kumashumi eminyaka emithini kwaye iyakhutshwa xa kugawulwa imithi.

Ukongeza, enye into ekufuneka ithathelwe ingqalelo kukuba, nangona imithi ingagawulwa ukuze kukhutshwe iinkuni, kufuneka ithathelwe ingqalelo ukuba ukuba le mithi ayiphili kwiziphumo zemozulu, iyakuthi nayo ikhabhoni eqokelelweyo iphinda ibuyiselwe emoyeni.

Ababhali baqukumbela ngelithi ukunyuka kwamaqondo obushushu kunye namaxesha awomileyo kuya kunciphisa ukukhula kwaye kunciphise ixesha lokukhula elifanelekileyo kwisiqingatha sesibini senkulungwane yama-XNUMX, esinokubangela ukubola kwezinto kunye nokwandisa amazinga okusweleka kwemithi.
