Pattern and control of organic matter accumulation in surface layers and sediments
The entire ecosystem relies on the recycling of organic matter (and the nutrients it contains), including dead plants, animals, and other organisms. Decomposition of organic matter and its movement through the ecosystem is an important component of the food web.
Earthworms effects on soil respiration in a sub-tropical wet forest in Puerto Rico
Poster Number: 254 Presenter/Primary Author: Grizelle Gonzalez Carbon storage, as well as other ecosystem services of soils, is an emergent property on the landscape scale that can be attributed to mechanisms occurring on scales orders of magnitude smaller.
Ecological Homogenization of Urban America
Poster Number: 249 Presenter/Primary Author: Peter Groffman Urban, suburban and exurban ecosystems are important and increasing in the U.S. An apparent, but functionally untested result of urban land use change is homogenization across cities, where n
Organic matter contribution and decomposition by ectomycorrhizal fungi in response to chronic nitrogen deposition in a temperate mixed-hardwood forest
Poster Number: 248 Presenter/Primary Author: Jesse Sadowsky Ectomycorrhizal (ECM) fungi comprise a large proportion of total soil microbial biomass, contribute belowground inputs as mycelia that may equal or surpass those of roots, and secrete enzymes that
Patterns of soil properties and respiration along an elevation gradient in the Luquillo Mountains of Northeastern Puerto Rico
Poster Number: 247 Presenter/Primary Author: Dingfang Chen As an important component in global carbon cycle, soil respiration is one of the primary paths to release carbon fixed by vegetation to the atmosphere.
High Frequency Monitoring of the Quantity and Quality of Dissolved Organic Matter Flux Between Salt Marshes and Plum Island Sound, MA
Poster Number: 242 Presenter/Primary Author: Yong Zhao Salt marshes are highly productive continental margin ecosystems, due to abundant solar radiation, water, and nutrients provided by tidal water.
