Many insect species undertake multigenerational migrations in the Afro-tropical and Palearctic ranges, and understanding their migratory connectivity remains challenging due to their small size, short life span and large population sizes. Hydrogen isotopes (δ²H) can be used to reconstruct the movement of dispersing or migrating insects, but applying δ²H for provenance requires a robust isotope baseline map (i.e. isoscape) for the Afro-Palearctic.

用于追踪非洲-古北界草食性鳞翅目动物迁徙的氢等景观


许多昆虫物种在非洲热带和古北区进行多代迁徙，由于它们体型小、寿命短和种群规模大，了解它们的迁徙连通性仍然具有挑战性。氢同位素 (δ ² H) 可用于重建分散或迁徙昆虫的运动，但应用 δ ² H 进行起源需要稳健的同位素基线图（即等位图）非洲-古北界。
