Ukuzwa okukude kwe-pigment yeqabunga kuzothuthukisa ukuqagela kwesimo sezulu

Izitshalo akuzona izidalwa ezikhiqiza umoya-mpilo odingeka kakhulu, kepha manje zingasiza nososayensi ukuthi bathuthukise amamodeli wokushintsha kwesimo sezulu sibonga inqubo eyenziwe ngu UJosep Penuelas, umcwaningi e-Center for Ecological Research and Forest Applications (CREAF-UAB).

Le ndlela, ngokususelwa ekuhlaziyweni kwezithombe ezikude ezitholwa kuma-satellite, kuzovumela abacwaningi ukuthi babe nombono ocacile futhi omfushane ngekusasa elisilindeleyo.

Kunezinhlobo eziningi zama-conifers, njengepayini noma ama-firs, okuthi, njengezitshalo ezihlala ziluhlaza, kube nzima kakhulu kososayensi ukuthola ukuthi i-photosynthesis eyenziwa yilawa maqabunga ishintsha kanjani unyaka wonke. Kodwa-ke, manje sebethole ukuthi ezinyangeni ezibandayo ukukhiqizwa kwe-chlorophyll (i-pigment enikeza umbala oluhlaza ukuthi ushiye futhi obhekele i-photosynthesis) kuncishisiwe ngokuthanda ezinye izingulube: i-carotenoids (ebomvu ngombala). noma iwolintshi).

Ngenxa yokuzwa okukude okuvela kuziphuphutheki zenani lama-chlorophyll nama-carotenoids, bazokwazi ukuqopha zonke izinguquko zonyaka, ezinye izinguquko ngokuya kukaPeñuelas zihlangana futhi zilandele iphethini efanayo nezinga le-photosynthetic kanye nokukhiqizwa okuyisisekelo ngokuphelele kwe-ecosystem, okuyinani eliphelele le-carbon dioxide eligcinwe emaqabungeni ngesikhathi se-photosynthesis.

Ngakho-ke, ukwazi inani le-chlorophyll ne-carotenoids, bazokwazi ukwenza ukulinganisela okungcono kwenani lekhabhoni elisetshenziswa ezindaweni ezahlukahlukene zemvelo unyaka wonke, okuzosiza ukwenza ukubonakala okungcono kokuguquka kwesimo sezulu ngoba lesi yisimo esiguqula imijikelezo yezitshalo.

Ukwazi imiphumela yezinguquko ebezenzeka esimweni sezulu kokubili ezitshalweni nasezilwaneni kuzosisiza siqonde ukuthi kwenzekani emhlabeni.
