Aim Initiation of autumnal leaf senescence is crucial for plant overwintering and ecosystem dynamics. Previous studies have focused on the advanced stages of autumnal leaf senescence and reported that climatic warming delayed senescence, despite the fundamental differences among the stages of senescence. However, the timing of onset of leaf coloration ( D LCO ), the earliest visual sign of senescence, has rarely been studied....

Aim Local environmental selection and lineage admixture have long been accepted as important adaptive mechanisms in adjusting widespread taxa to new environments. We studied a pond skater, Gerris latiabdominis , to explore the relative roles played by these two mechanisms in its process of adaptation to heterogeneous landscapes. Location East Asia. Taxon Gerris latiabdominis Miyamoto, 1958. Methods Mitochondrial (COI, COII) an...
