SHIFTS OF SOIL MICROBIAL COMMUNITIES IN ALASKAN TUNDRA IN RESPONSE TO LONG-TERM WARMING
(2016-08)
Permafrost regions store about 33% of the world’s soil organic carbon, and are believed to rapidly respond to global warming. The degradation and release of previously stored organic carbon stocks lead to positive feedbacks, ...
Cell Wall Alterations During Lateral Root Emergence in Oryza Sativa
(2016)
In rice seedlings, lateral roots (LRs) develop through several layers of extant tissues, including multiple cortex cell layers, as well as single files of sclerenchyma, exodermis, and epidermal cells. In contrast to typical ...
Impact of Photooxidation and Biodegradation on the Fate of the Oil Spilled During the Deepwater Horizon Incident: The Advanced Stages of Weathering
(2016-12)
The major biogeochemical forces influencing the environmental fate of spilled oil have been intensively investigated for many decades. The sinking and burying of spilled residual oil to form large mats that subsequently ...
Herbivory, not soil nitrogen, alters grassland plant community structure and decomposition
(2016-12)
Human activity has shifted grazing and nitrogen (N) altering plant community structure worldwide. Plant community changes are expected to alter associated ecosystem functions (e.g., plant litter decomposition). Few studies ...
CHARACTERIZATION OF FUNGAL CONTAMINANTS IN B20 BIODIESEL STORAGE TANKS AND THEIR EFFECT ON FUEL COMPOSITION
(2016-08)
The liquid transportation fuel B20 biodiesel is an 80:20 blend of petroleum-derived
ultra-low sulfur diesel (ULSD) and biodiesel. Although B20 biodiesel represents a
fungible fuel with a reduced carbon footprint compared ...
Substitutional Analysis of Cysteine Residues and Preliminary Regulon Analysis of the Redox-Sensing Transcription Regulator MsvR in Methanosarcina acetivorans
(2016-12)
Methane produced from methanogenesis in archaea may be a promising source of renewable energy as methanogens are the primary producers of biogenic methane. However, methanogens are anaerobic and experience transient oxygen ...
ESTABLISHMENT OF A RARE RIPARIAN TREE, ALNUS MARITIMA
(2016-12-16)
Alnus maritima is a rare, riparian tree species showing no recruitment from seeds. We conducted studies to identify factors potentially limiting establishment. First, we surveyed current known populations to determine ...
