(2017-11-14)Subterranean estuaries extend into carbonate platforms where extensive cave networks influence the hydrology and biogeochemistry of the coastal aquifer. How complex biological communities thrive in this globally-distributed, ...
-
(2020-07-22)The Arctic Ocean is characterized by broad continental shelves, large river inputs, sea ice coverage, and limited exchange with other major ocean basins. This provides a unique environment in which to examine the distribution ...
-
(2018-05-09)Urban lotic surface waters have been extensively studied due to reported increases in their alkalization and dissolved organic carbon (DOC). However, urban lentic surface waters, which are subject to the same United States ...
-
(2012-07-16)Woody plant encroachment is a globally-prevalent vegetation change phenomenon that has shifted grass-dominated ecosystems to mixed grass and woody plant matrices over the last century. In the Rio Grande Plains of Texas, ...
-
(2020-11-22)Bottomland hardwood forests (BHFs) along the Gulf coast of Texas have been experiencing a combination of disturbances in the form of hydroclimate changes and excessive anthropogenic nitrogen (N) deposition, both of which ...
-
(Texas A&M University, 2005-11-01)Seagrass productivity is largely limited by nutrient and light availability. However, increasing evidence suggests that sedimentary geochemical processes may play an essential role in seagrass productivity/health. Much ...
-
(2009-05-15)Our ability to understand and predict the fate and transport of contaminants in natural systems is vital if we are to be successful in protecting our water resources. One important aspect of understanding chemical fate and ...
-
(2019-05-16)Understanding the responses of savanna communities to disturbance and altered resource conditions will gain importance under climate-change induced modifications to precipitation patterns and nutrient cycling. This study ...
-
(2012-02-14)The overall objective of the research presented here was to combine multiple geochemical parameters and molecular characterizations to provide a novel view of active microbial community ecology of sediments in a large-river ...
-
(Texas A&M University, 2008-10-10)Marine aggregates are an important means of carbon transfers downwards to the deep ocean as well as an important nutritional source for benthic organism communities that are the ultimate recipients of the flux. During these ...
-
(2010-01-14)Three laboratory studies were performed to elucidate the influence of soil texture, pH, and cation exchange capacity (CEC) on the concentration of ferrous Fe in soil solution and the resulting expression of soil redoximorphic ...
-
(Texas A&M University, 2004-11-15)Bottom water hypoxia and its influence on the environment have been topics of increasing concern for many coastal regions. This research addresses both spatial and temporal variability in sediment biogeochemistry at the ...
