Benefits from the Sea:Sentinel Species and Animal Models of Human Health
Benefits from the Sea Sentinel Species Animal Models Human Health
2015/7/23
Much of the current interest in the impact of the oceans on human health can be traced historically back to the earliest days of the fields of Experimental Marine Biology and Comparative Physiology. I...
The Biology and Ecology of Tintinnid Ciliates:Models for Marine Plankton
Biology and Ecology Tintinnid Ciliates Marine Plankton
2015/7/16
Single-celled eukaryotes called protists are vitally important to marine ecosystems. Protists with chloroplasts (algae) carry out most of the primary production in the sea. What feeds on this algal pr...
Getting the ‘‘right’’ parameter values for models of the pelagic microbial food web
Getting the rightp arameter values models pelagic microbial food web
2014/4/2
The microbial part of the pelagic food web is believed to be a highly dynamic and tightly coupled network in which system behavior emerges from organism properties and interactions. A central goal in ...
Trait-based models of nutrient uptake in microbes extend the MichaelisMenten framework
Trait-based models nutrient uptake microbes extend MichaelisMenten framework
2014/4/2
In microbial competition theory, the Michaelis-Menten (MM) half-saturation coefficient is often considered to be a trait of an organism defining competitive strength in a trade-off conflict with maxim...
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 ...
Accounting for grazing dynamics in nitrogen-phytoplankton-zooplankton (NPZ) models
Accounting for grazing dynamics nitrogen-phytoplankton-zooplankton (NPZ) models
2014/4/23
Nitrogen-phytoplankton-zooplankton (NPZ)-type models are widely used to explore the dynamics of marine planktonic ecosystems. Within these models, grazing by zooplankton on phytoplankton that are subj...
Biogeochemical cycling in the oligotrophic ocean: Redfield and non-Redfield models
Biogeochemical cycling oligotrophic ocean Redfield non-Redfield models
2014/5/9
The assumption of fixed elemental ratios in ocean biogeochemical models was tested using the Hawaii Ocean Time-Series data set from the subtropical North Pacific Ocean, where nutrient-starvation is a ...
Do we need complex mechanistic photoacclimation models for phytoplankton?
complex mechanistic photoacclimation models phytoplankton
2014/5/22
The outputs of simple models relating phytoplankton growth and chlorophyll a (Chl a) to irradiance and nutrient (nitrogen [N] and/or iron [Fe]) availability are compared with those of complex mechanis...
A comparison of two N-irradiance interaction models of phytoplankton growth
two N-irradiance interaction models phytoplankton growth
2014/6/10
The N-photoacclimation interaction models of Geider et al. (GM) and Flynn et al. (FM) are compared by tuning them to data from a light-shift experiment for a diatom. Both the original model constructs...
Use of size spectra and empirical models to evaluate trophic relationships in streams
size spectra trophic relationships in streams
2014/6/9
We measured the biomass size distributions of algae, protozoa, and invertebrates in several streams of Eastern Ontario and Western Quebec and related assemblage biomass to nutrient (nitrogen and phosp...
