Abstract: In the continuous permafrost zone, unfrozen ground may exist beneath large lakes and streams. Sub‐lake taliks that extend through permafrost provide a potential conduit for subpermafrost groundwater to reach the surface, increasing dissolved ion concentrations… read more here.

Abstract: Despite low species diversity and primary production, trophic structure (e.g., top predator species, predator size) is surprisingly variable among Arctic lakes. We investigated trophic structure in lakes of arctic Alaska containing arctic char Salvelinus alpinus… read more here.
