EMPOWER-1.0:an Efficient Model of Planktonic ecOsystems WrittEn in R
EMPOWER-1.0 Planktonic ecOsystems WrittEn in R
2015/8/6
Modelling marine ecosystems requires insight and judgement when it comes to deciding upon appropriate model structure, equations and parameterisation. Many processes are relatively poorly understood a...
Resilient Ecosystems,Healthy Communities:Human Health and Sustainable Ecosystems After the December 2004 Tsunami
Resilient Ecosystems Healthy Communities Human Health Sustainable Ecosystems December 2004 Tsunami
2015/7/23
Human health and wellbeing are closely linked to the health and resilience of ecosystems. When natural disasters occur in situations where natural resources have been severely degraded, it is much mor...
Dynamics of Marine Ecosystems:Biological-Physical Interactions in the Oceans (Third Edition)
Dynamics of Marine Ecosystems Biological-Physical the Oceans
2015/7/23
In 1991, Kenneth Mann and John Lazier published the first edition of Dynamics of Marine Ecosystems (DME). Subtitled "Biological-Physical Interactions in the Oceans," DME was an ambitious attempt to de...

2015/7/22
If nothing else, research in deep-sea environments teaches us how little we know about such important and productive habitats. The relatively recent discovery of hydrothermal-vent and cold-seep ecosys...
Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...
ICES and PICES Strategies for Coordinating Research on the Impacts of Climate Change on Marine Ecosystems
Coordinating ICES and PICES
2015/7/20
The social, economic, and ecological consequences of projected climate change on fish and fisheries are issues of global concern. In 2012, the International Council for the Exploration of the Sea (ICE...
Taking the Pulse of Marine Ecosystems: The Importance of Coupling Long-Term Physical and Biological Observations in the Context of Global Change Biology
Coupling Long-Term Physical Biological Observations
2015/7/16
Research programs that co-locate environmental sensors with "biology" can enable the linking of environmental data with changes in biological or ecological processes. The coastal and marine Long Term ...
Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models
Sea continental shelf the ecosystem nutrition structure global ocean ecosystem dynamics
2015/7/16
End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the North...
Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
The Roles of Large Top Predators in Coastal Ecosystems: New Insights from Long Term Ecological Research
New Insights Long Term Ecological Research
2015/7/16
During recent human history, human activities such as overhunting and habitat destruction have severely impacted many large top predator populations around the world. Studies from a variety of ecosyst...
Trophic Relationships and Diet of Consumers in Temperate Kelp Forest and Coral Reef Ecosystems
Temperate Kelp Forest Coral Reef Ecosystems
2015/7/16
We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical ...
Coastal Transport Processes Affecting Inner-Shelf Ecosystems in the California Current System
California Current System Processes Affecting Inner-Shelf Ecosystems
2015/7/16
Wind-driven upwelling is weak and intermittent in the Southern California Bight, a region sheltered from the strong, prevailing equatorward winds typical of most of the California Current System. Thus...
The importance of Dissimilatory Nitrate reduction to ammonium (DNra) in the Nitrogen cycle of coastal ecosystems
Dissimilatory Nitrate Nitrogen cycle
2015/7/16
Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...
Recent Arctic Climate Change and Its Remote Forcing of Northwest Atlantic Shelf Ecosystems
Climate Change Northwest Atlantic Shelf Ecosystems
2015/7/15
During recent decades, historically unprecedented changes have
been observed in the Arctic as climate warming has increased precipitation, river
discharge, and glacial as well as sea ice melting. ...
