Productivity of kelp forests, sans the iconic kelp
kelp forests environmental change ecosystem forest canopy
2021/8/5
A lush canopy is a defining feature of most of the planet's forests. But canopy-forming species can be particularly vulnerable to disturbances and environmental change. So the question is: What is a f...

Comparing Process-Based Net Primary Productivity Models in a Mediterranean Watershed
NPP Modelling Remote Sensing Percent Tree Cover Model Comparison CASA LPJ-GUESS
2014/4/22
The aim of this study was to compare the estimation capability of two different process-based NPP models (CASA and LPJGUESS) in a Mediterranean watershed. Remotely sensed data and climate time series ...
Severe droughts reduce estuarine primary productivity with cascading effects on higher trophic levels
higher trophic levels Severe droughts reduce estuarine
2014/4/4
Using a 10-yr time-series data set, we analyzed the effects of two severe droughts on water-quality and
ecosystem processes in a temperate, eutrophic estuary (Neuse River Estuary, North Carolina). Du...
Top-down and bottom-up influences of jellyfish on primary productivity and planktonic assemblages
Top-down and bottom-up jellyfish on primary productivity planktonic assemblages
2014/4/17
A manipulative mesocosm experiment was done in a saline coastal lake in Australia to compare the top-down and bottom-up influences of jellyfish on primary production and planktonic assemblages. We hyp...
Evidence of warming effects on phytoplankton productivity rates and their dependence on eutrophication status
warming effects phytoplankton productivity rates eutrophication status
2014/4/17
Using 31-yr data from measurements in a lake that has experienced change in eutrophication status, I showed that the effects of global warming on chlorophyll a (Chl a)–normalized maximum rates of phot...
