Common water hyacinth remains the oldest and most widely spread invasive aquatic plant in Louisiana as evidenced by Figures 4-6. Alligator weed infestation in 41 HUC of Louisiana made it the highest among all other species. Recently, giant Salvinia aggressive nature is causing a widespread in the State waterways within the short time of introduction. […]

There has been an increasing and competing demand for other water uses in urban areas
An early concern with the planting of trees and shrubs in channels was they would be too effective and cause the channel to migrate, especially in areas where the original channel was some distance, and lower, than the constructed channel. Although more sinuosity in a channelized stream might ultimately be a desirable objective, in the […]
Their presence in a mangrove forest shows that the system had been disturbed by humans
Most of the weeds found in this study are dominant because they are all aquatic and lowland weeds that benefit from the closeness of the area to a river. The change in the habitat from swampy to sandy soil contributed to the transition from exclusively a mangrove community to a weed community. Loss of mangrove […]
SWIR bands 2 – 8 were a necessity for differentiating between the plant species
Those indices are sensitive to moisture content in plant leaves suggesting leaf succulence was important in crop weed separation and weed to weed separation. The SWIR band serves as a measure of water content, leaf internal structure, and dry matter; whereas, the NIR band serves as measurement of only leaf internal structure and dry matter […]
Percentages were taken as a single main-plot value
Spot applications of glyphosate at the same rate previously mentioned were also utilized to control perennial weed species, Canada thistle and field horsetail , within all plots. Weed control treatments were initially applied in the spring of 2008. Data were collected for the growing seasons of 2008 and 2009. Dormant season data were collected in […]
Pitted morning glory control was 48% 2 WAP2 in 2012 with the flumioxazin PRE only treatment
By tank mixing additional modes of action with dicamba, growers will be able to effectively manage glyphosate and ALS-resistant Palmer amaranth and other troublesome broadleaf weeds while helping to minimize the selection of dicamba resistant weed biotypes. The ability to use either dicamba, glyphosate, or a tank-mix of both herbicides before planting or at selected […]
Eight seeds from each accession were germinated for sprout selection
Limitations with X-Ray CT include the complicated equipment required for the survey and the extensive job of distinguishing roots against soils. Consequently, the images obtained were not exceptionally clear but did give a broad depiction of the area covered. For example, small roots were not distinguishable from the soil matrix . Similarly, shovelomics will generate […]
The weed often gets caught in boats and the plant fragments are carried to new areas
Hecky and Bugenyi obtained higher concentrations of phosphorus near the mud surface than the upper photosynthetic zone. Hence the high coverage of S. molesta near the shoreline areas may be linked to the rich organic material usually found at the lake bottoms along the shorelines. This is reflected by the high phosphate levels in Acholi […]
Frequency of marijuana use is operationalized as six options presented to respondents
Their study demonstrates the importance of proper controls to limit the use of unique IDs to one person; implementing such controls is relatively easy in a web-based survey environment.Though unaddressed by Wejnert and Heckathorn due to the nature of their study, web RDS poses an additional complicating feature with hidden populations, particularly those who are […]
Does the composition of marijuana users’ friendship networks affect their use of the drug?
It is also possible that the higher proportion of patients with schizophrenia and schizoaffective disorder in this study is associated with lower rates of substance use due to a limited access to substances. Although schizophrenia was found to be a protective factor of substance use in this study as well as in other studies , […]
