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...

Increased stratification and mixed layer shoaling of the surface ocean resulting from warming can lead to exposure of marine dinitrogen (N 2 )‐fixing cyanobacteria to higher levels of inhibitory ultraviolet (UV) radiation. These same processes also reduce vertically advected supplies of the potentially limiting nutrient phosphorus (P) to N 2 fixers. It is currently unknown how UV inhibition and P limitation interact to affect...
