Species- and community-level responses combine to drive phenology of lake phytoplankton Species- and community-level responses combine to drive phenology of lake phytoplankton
Global change is leading to shifts in the seasonal timing of growth and maturation for primary producers. Remote sensing is increasingly used to measure the timing of primary production in both aquatic and terrestrial ecosystems, but there is often a poor correlation between these results and direct observations of life-history responses of individual species. One explanation may be that...

The density dilemma: limitations on juvenile production in threatened salmon populations The density dilemma: limitations on juvenile production in threatened salmon populations
Density-dependent processes have repeatedly been shown to have a central role in salmonid population dynamics, but are often assumed to be negligible for populations at low abundances relative to historical records. Density dependence has been observed in overall spring/summer Snake River Chinook salmon Oncorhynchus tshawytscha production, but it is not clear how patterns observed at the...
