Microbial Community, Functioning, And Its Relationship With Heavy Metals In An Urban Brownfield, Jay Prakash Singh
Microbial Community, Functioning, And Its Relationship With Heavy Metals In An Urban Brownfield, Jay Prakash Singh
Theses, Dissertations and Culminating Projects
The ubiquity of urban brownfields presents a challenge for environmental managers for managing degraded ecosystems that are in close contact with human habitation. Presence of metal contaminants in brownfields further complicate the matters as it cannot be degraded and hence pose a high risk to human and environmental health, and well-being of the local community. However, previous studies indicate that management and restoration of brownfields are possible through the use of low input longer term and sustainable remediation approaches. These sustainable approaches include the use of plants, fungi, and bacteria to increase soil function and mitigate risks from the contaminants. …
Assessment Of Mean Annual Precipitation And Pco₂ Effect On C₃ Land Plant Carbon Isotope Fractionation, Woohee Kim
Assessment Of Mean Annual Precipitation And Pco₂ Effect On C₃ Land Plant Carbon Isotope Fractionation, Woohee Kim
Theses, Dissertations and Culminating Projects
Modern carbon dioxide (CO2) levels are well known from instrumental observation (just exceeded 415 ppmv on May 13th, 2019). CO2 levels (pCO2) in the past, however, are difficult to obtain, especially for geologic time older than 800 thousand years (kyr). Many proxies have been used to infer past CO2 levels in the geologic records, but the results are often incomplete and inconsistent. Here, I assess the uncertainty of a new pCO2 proxy that has great potential to reconstruct continuous pCO2 records across the entire Phanerozoic. This new proxy is based on stable …
Exploring The Role Of Evaporation And Precipitation Rates On Mangrove Island Morphology, Isamar M. CortéS
Exploring The Role Of Evaporation And Precipitation Rates On Mangrove Island Morphology, Isamar M. CortéS

Mangroves are salt tolerant species of trees that grow in tropical and subtropical environments. Mangroves provide ecosystem services to societies along marine environments, including storm protection, coastal biodiversity, and blue carbon storage. However, as the importance of mangrove ecosystems has become clearer over recent years, their coverage has been reduced through mismanagement and climate impacts. For instance, in terms of climate warming, mangroves cannot survive under abnormally high rates of net evaporation when soil stressor concentrations (e.g., sulfate, sulfide) increase above threshold conditions. To study the effects of this climate driver phenomenon on mangrove islands, we are examining mangrove islands, …
