High Arctic lakes as sentinel ecosystems: Cascading regime shifts in climate, ice cover, and mixing
High Arctic lakes sentinel ecosystems Cascading regime shifts climate ice cover mixing
2014/4/17
Climate and cryospheric observations have shown that the high Arctic has experienced several decades of rapid environmental change, with warming rates well above the global average. In this study, we ...
The effects of grazing by the snail, Lymnaea elodes, on benthic N2 fixation and primary production in oligotrophic, arctic lakes
snail Lymnaea elodes on benthic N2 fixation primary production oligotrophic arctic lakes
2014/4/21
This study assessed whether grazing by the snail, Lymnaea elodes, limits benthic dinitrogen (N2) fixation and primary production in nitrogen (N)-limited oligotrophic lakes near Toolik Field Station on...
Stable isotope signatures of benthic invertebrates in arctic lakes indicate limited coupling to pelagic production
Stable isotope signatures benthic invertebrates
2014/4/23
We tested the hypotheses that benthic macroinvertebrates, especially chironomid larvae in the Tribe Chironomini,
from small oligotrophic arctic lakes are only weakly linked to pelagic food sources, a...
