Bišu (Hymenoptera: Anthophila) daudzveidība intensīvi un ekstensīvi apsaimniekotās lauksaimniecības teritorijās

2022

Savvaļas bites ir pasaulē nozīmīgi apputeksnētāji gan savvaļas veģetācijai, gan kultūraugiem. Eiropā un īpaši Latvijā bišu pētniecībā trūkst uzziņu par bišu sastopamību, izplatību un to spēju pielāgoties pieaugošai antropogēnajai ietekmei biotopos. Bišu daudzveidību dabā vienlaicīgi ietekmē daudzi ārēji faktori un to mijiedarbība ar bišu fenotipiem. Bakalaura darbā pētīta bišu daudzveidība divās dažādi apsaimniekotās lauksaimniecības teritorijās Saldus novadā 2021. gada vasarā. Paraugu ievākšanā tika izmantota ūdens lamatu metode. Bišu daudzveidība tika analizēta, izmantojot jauktu efektu modeļus. Uzskaitēs kopā ievākti 2175 indivīdi 96 dažādās bišu sugās. Bišu daudzveidība novērota būtiski…
