Previous research concerning climate change in the United States clearly illustrates the necessity for observing how ecological systems are influenced by natural disasters (Staudinger et. al. 2013; Nelson et. al. 2013). Traditionally, ecology is concerned with the relationships between organisms (human and other living beings) and their environment (Tyler & Spoolman, 2013). Human understanding of how organisms are affected by, how they adapt to, and how they work to sustain their environment has become even more diverse in recent years (Staudinger et. al. 2013). This may be due to a number of environmental factors that have occurred in recent years. However, this paper seeks to examine the ecological effects of the wind factor. In particular, we address the ecological effects of hurricanes as it relates to (1) environmental outcomes and alterations among organisms in the United States, (2) the well-being and adaptation of human and organismic life (i.e. animals, plants, etc.) post Hurricane Katrina and Camille (3) and how hurricanes alter and transform health and restoration patterns in the U.S.

Trichloroethylene (TCE) releases from leaks and spills next to a large government building occurred over several decades with the most recent event occurring 20 years ago. In response to a perceived conventional vapor intrusion (VI) issue a sub-slab depressurization system (SSDS) was installed 6 years ago. The SSDS is operating within design limits and has achieved building TCE vapor concentration reductions. However, subsequent periodic TCE vapor spikes based on daily HAPSITE™ measurements indicate additional source(s). Two rounds of smoke tests conducted in 2017 and 2018 involved introduction of smoke into a sanitary sewer and storm drain manholes located on effluent lines coming from the building until smoke was observed exiting system vents on the roof. Smoke testing revealed many leaks in both the storm sewer and sanitary sewer systems within the building. Sleuthing of the VI source term using a portable HAPSITE™ indicate elevated vapor TCE levels correspond with observed smoke emanation from utility lines. In some instances, smoke odors were perceived but no leak or suspect pipe was identified suggesting the odor originates from an unidentified pipe located behind or enclosed in a wall. Sleuthing activities also found building roof materials explain some of the elevated TCE levels on the 2nd floor. A relationship was found between TCE concentrations in the roof truss area, plenum space above 2nd floor offices, and breathing zone of 2nd floor offices. Installation of an external blower in the roof truss space has greatly reduced TCE levels in the plenum and office spaces. Preferential VI pathways and unexpected source terms may be overlooked mechanisms as compared to conventional VI.

Environmental factors that affect the growth and development of onionweed were evaluated in order to predict its potential range and impact in the U.S. In controlled-environment experiments, onionweed achieved 60 to 100% of its maximum vegetative growth at temperatures ranging from 18/11 to 30/23 C day/night. The greatest biomass was produced at day temperatures of 18 or 24 C and night temperatures of 11 or 17 C. Leaf production and reproductive development were greatest at 18/11 C. Plants eventually flowered also at 18/17, 24/17, and 24/11 C but not in any regime with a 30 C-day or a 23 C-night. Flowering occurred earlier in 16-h photoperiods than in 16-h photoperiods than in 8-h photoperiods. Climatic analyses revealed no U.S. analogs of the principal Australian onionweed sites. Based on its environmental responses and its pattern of distribution as a weed in Australia, onionweed will likely remain confined to the southwestern U.S.
