Giant Salvinia, Salvinia Molesta (Salviniaceae): Evaluation Of Sub-Optimum Temperatures On Survival Of The Giant Salvinia Weevil, Cyrtobagous Salviniae (Coleoptera: Curculionidae) And Integration Of Management Practices With Aquatic Herbicides, Lauren W. Cozad
LSU Master's Theses
Salvinia molesta is one of the world’s worst aquatic weeds and has cost Louisiana nearly $7 million worth of damage and economic impact each year. While aquatic herbicides and the biological control agent, Cyrtobagous salviniae, are the most efficacious control methods, there are limitations with each technology. Therefore, studies were conducted to evaluate insect mortality at upper and lower lethal temperatures and investigate integrated pest management (IPM) with insects and herbicides. Three Louisiana populations of C. salviniae were tested to evaluate cold tolerance and found that at 0°C, the Bayou Nicholas population was 1.3- and 1.4-times more cold tolerant …
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
The Effects Of Isoprene Emission From Native And Invasive Trees On Local Air Quality, Aarti P. Mistry
DePaul Discoveries
Biogenic volatile organic compounds (BVOC) are the second-most abundant reactive gasses emitted into the atmosphere by the biosphere. Isoprene is a BVOC produced by the process of photosynthesis from vegetation and is emitted from plant leaves. Isoprene is a hydrocarbon that combines with oxides of nitrogen in the atmosphere to create ozone in the troposphere, an air pollutant. Invasive trees alter ecosystems and affect native tree populations. Invasive tree species in the Chicagoland area are outcompeting native tree species and expanding rapidly. The effect of isoprene emissions on air quality is a well-researched area in the atmospheric science community, however, …
Surveying The Distributions Of Melaleuca Quinquenervia, Psidium Cattleianum, And Litsea Glutinosa At Analalava Special Reserve, Hanusia Higgins
Surveying The Distributions Of Melaleuca Quinquenervia, Psidium Cattleianum, And Litsea Glutinosa At Analalava Special Reserve, Hanusia Higgins
Independent Study Project (ISP) Collection
This study surveyed the distributions of three invasive plant species, Melaleuca quinquenervia, Psidium cattleianum, and Litsea glutinosa at the Analalava Special Reserve in Mahavelona, Madagascar. Analalava is a 229-hectare degraded patch of low-elevation humid forest on the northeast coast of Madagascar, and one of the last forest fragments remaining in the region. It is a haven for biodiversity, containing 343 recorded species of plants, 12 of which are locally endemic. Invasive species are considered the second-most significant threat to biodiversity, both worldwide and specifically at Analalava. Based on a systematic transect survey of these three targeted invasive species, their distributions …
