Ushbu maqolada global iqlim o‘zgarishining o‘simliklar va hayvonlar populyatsiyalariga ta’siri, shuningdek, ularning genetik darajadagi moslashuv jarayonlari tahlil qilinadi. Iqlimning global miqyosdagi isib borishi, yog‘ingarchilik rejimlarining o‘zgarishi, ekstremal ob-havo hodisalarining ko‘payishi va ekotizimlarning noturg‘unlashuvi biologik xilma-xillikka bevosita ta’sir ko‘rsatmoqda. Bu holatga javoban o‘simliklar va hayvonlar hayotiy strategiyalarini, reproduktiv mexanizmlarini va genetik tarkiblarini moslashtirishga majbur bo‘lmoqda.
Maqolada genetik moslashuvning asosiy yo‘nalishlari sifatida allel chastotalarining o‘zgarishi, genomik mutatsiyalar, epigenetik reaktsiyalar va fenotipik plastiklik tahlil etiladi. Shu bilan birga, o‘simliklar va hayvonlarda kuzatilayotgan yangi evolyutsion strategiyalar — masalan, tezlashtirilgan avlod almashinuvi, migratsion yo‘nalishlarning o‘zgarishi, yashash muhitiga nisbatan sezuvchanlikning oshishi va endemik turlarning genetik diversifikatsiyasi — ilmiy dalillar bilan asoslab beriladi.
Tadqiqotda molekulyar biologiya, ekologiya, biogeografiya va bioinformatika metodlariga tayanilgan holda, klimatik o‘zgarishlarga moslashuv jarayonlarining zamonaviy yondashuvlari yoritilgan. Maqola oxirida o‘simlik va hayvon turlarining genetik resurslarini saqlab qolish bo‘yicha tavsiyalar keltirilgan. Ushbu tadqiqot global biologik xavfsizlik va barqaror ekotizimlar ta’minotida muhim nazariy va amaliy ahamiyatga ega.
