IUBS yakhala membala kuyambira 1925.
Bungwe la International Union of Biological Sciences (IUBS) linakhazikitsidwa mu 1919 kuti lipititse patsogolo maphunziro a sayansi ya zamoyo: kuyambitsa ndi kugwirizanitsa kafukufuku, kulimbikitsa mphamvu ndi ntchito zina za sayansi zomwe zimafuna mgwirizano wapadziko lonse, wamagulu osiyanasiyana; kuwonetsetsa kukambirana ndi kufalitsa zotsatira za kafukufuku wogwirizana, makamaka zokhudzana ndi mapulogalamu a sayansi a IUBS; kulimbikitsa dongosolo la misonkhano yapadziko lonse ndikuthandizira kufalitsa malipoti awo.
Mapulogalamu asayansi a IUBS ndi amitundu yosiyanasiyana; zimachitidwa mogwirizana ndi akuluakulu a sayansi ya dziko komanso mogwirizana ndi mabungwe ena apadziko lonse, onse apakati pa maboma (UNESCO, UNEP, FAO, EC, etc.) ndi omwe si a boma. Mapulogalamuwa amayang'ana zovuta za biology, biodiversity, bioethics, biotechnology, bio-indicators, biological education, biological nomenclature, biosystematics, reproductive biology ndi aquaculture, biology zovuta ndi zina. IUBS imasindikiza magazini ya kotala, Biology International, yomwe imatumiza uthenga wa mapologalamu ndi zochita za Union kwa Mamembala a IUBS ndi mabungwe ogwirizana ndi anthu pawokha.
Umembala wa IUBS pakadali pano uli ndi mamembala wamba 44, omwe amatsatira kudzera ku Academies of Sciences, National Research Councils, mabungwe asayansi padziko lonse kapena mabungwe ofanana, ndi mamembala asayansi 80, onse omwe ali mabungwe asayansi apadziko lonse lapansi, kapena mabungwe ndi mabungwe osiyanasiyana azachilengedwe. .
Werengani zambiri za kusiyana pakati pa amuna ndi akazi mu polojekiti ya sayansi: Zomwe zasindikizidwa mu lipoti
