The regional and global significance of nitrogen removal in lakes and reservoirs
Human activities have greatly increased the transport of biologically available N through watersheds to potentially sensitive coastal ecosystems. Lentic water bodies (lakes and reservoirs) have the potential to act as ...
The savory swimmer swims north : a northern range extension of the blue crab Callinectes sapidus?
Worldwide, climate-change is shifting species distributions poleward. Here I present recent (2012-2014) observations of the blue crab, Callinectes sapidus, in the Gulf of Maine (GoM), north of its historical range of Cape ...
SeaBase : a multispecies transcriptomic resource and platform for gene network inference
Marine and aquatic animals are extraordinarily useful as models for identifying mechanisms of development and evolution, regeneration, resistance to cancer, longevity and symbiosis, among many other areas of research. ...
Linking ecology and economics for ecosystem management
(American Institute of Biological Sciences, 2006-02)
This article outlines an approach, based on ecosystem services, for assessing the trade-offs inherent in managing humans embedded in ecological systems. Evaluating these trade-offs requires an understanding of the biophysical ...
Microbial biogeography along an estuarine salinity gradient : combined influences of bacterial growth and residence time
(American Society for Microbiology, 2004-03)
Shifts in bacterioplankton community composition along the salinity gradient of the Parker River estuary and Plum Island Sound, in northeastern Massachusetts, were related to residence time and bacterial community doubling ...
Long-term survival of adult Arctic grayling (Thymallus arcticus) in the Kuparuk River, Alaska
(National Research Council Canada, 2004-12-23)
In many long-lived species such as Arctic grayling (Thymallus arcticus), population growth rate is most sensitive to changes in adult survival probabilities. Understanding the factors that regulate adult survival in this ...
Future effects of ozone on carbon sequestration and climate change policy using a global biogeochemical model
Exposure of plants to ozone inhibits photosynthesis and therefore reduces vegetation production and carbon sequestration. The reduced carbon storage would then require further reductions in fossil fuel emissions to meet ...
Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters
(American Meteorological Society, 2009-10-01)
The Massachusetts Institute of Technology (MIT) Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model’s first projections were published in 2003, ...
Consequences of considering carbon–nitrogen interactions on the feedbacks between climate and the terrestrial carbon cycle
(American Meteorological Society, 2008-08-01)
The impact of carbon–nitrogen dynamics in terrestrial ecosystems on the interaction between the carbon cycle and climate is studied using an earth system model of intermediate complexity, the MIT Integrated Global Systems ...
