Defining the “to” in end-to-end models [PDF]

open access: yes, 2009
Robust models relating climate change to fish production require an adequate description of planktonic intermediaries between phytoplankton and fish in end-to-end models.

Ecosystem services online: an overview of web-based resources [PDF]

open access: yes, 2013
2 pagesAs the concepts of ecosystem services and payments for ecosystem services (PES) have evolved, numerous web-based resources have been created to 1) provide and exchange information about ecosystem services, and 2) facilitate transactions between ...

Comparing machine learning-derived global estimates of soil respiration and its components with those from terrestrial ecosystem models

open access: yesEnvironmental Research Letters, 2021
The CO _2 efflux from soil (soil respiration (SR)) is one of the largest fluxes in the global carbon (C) cycle and its response to climate change could strongly influence future atmospheric CO _2 concentrations.

Spatio-temporal variability in fish-induced predation mortality on plankton: A simulation approach using a coupled trophic model of the Benguela ecosystem [PDF]

open access: yes, 2009
We investigate the potential predation pressure that would affect plankton communities spatially and seasonally using a coupled model, where fish-induced predation mortality is explicit. In the southern Benguela ecosystem, the fish model OSMOSE is forced

Characterization of river plume dynamics for a better water quality management

open access: yesFrontiers in Marine Science
Excessive riverine nutrient inputs are a main driver of eutrophication in marine waters. Thus, identifying areas most affected by river plumes is a key challenge for effective water quality management.

Model Selection for Ecosystem Respiration Needs to Be Site Specific: Lessons from Grasslands on the Mongolian Plateau

open access: yesLand, 2022
Selecting an appropriate model for simulating ecosystem respiration is critical in modeling the carbon cycle of terrestrial ecosystems due to their magnitude and high variations in time and space.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.
