Invasive Mustard plants have become a concern in Southern California by colonizing and invading disturbed areas in the Inland Empire, San Bernardino Mountains, San Gabriel Mountains, Mojave Desert and Colorado Desert. The two main mustard species that are invading Southern California are Black Mustard (Brassica nigra) and Sahara Mustard (Brassica tournefortii). Black Mustard is most commonly found in the Inland Empire and surrounding mountains, while Sahara Mustard is found at the lower elevations in the Colorado Desert and San Diego County. The mustard plants grow extremely fast as primary successors in a disturbed area. The plants secrete an allelopathic chemical that prevents the native plant seeds in the soil from germinating. The increase in mustard plants in mountainous areas has contributed to an increase in vegetation fires causing the normally chaparral type habitat …show more content…
Black Mustard (Brassica nigra) and Sahara Mustard (Brassica tournefortii) are the main two species that are invading Southern California. Both of these plants were brought to the United States via jump dispersal by early settlers. They now disperse through out the west using their adhesive seeds that stick to animal fur and vehicle tires. Mustard thrives in disturbed areas where fire or other disturbance has cleared an area of its native vegetation. The mustard is part of the primary succession after the disturbance has happened. The seeds from these plants can lie dormant in the soil for up to 40 years waiting for a disturbance to allow them to germinate. Many efforts are underway to control the invasive plant, but at least 64% of it needs to be extracted each year to make head way for its eradication. From this essay I have learned how large of a problem the mustard invasion really is. I have also realized that for progress to be made with this problem, more needs to be done then is being done
Did you know that you happen to be surrounded by invasive species? These species are animals that come into areas they do not belong in. The articles, “Invaders among Us,” and “Invader Alert,” show this. They harm the environment, cost tons of money in damage and extermination, and they have to be prevented.
Another interesting characteristic of chaparral plants is their ability to respond to fire and other natural disasters. Due to the dry and arid nature of the area, the sage and grasslands can easily cause brush fires. When the area is burned, the shrubs and plant life d...
Brassica rapa is a mustard plant that can be found throughout North America, and is common in areas undergoing extreme change, such as changes in climate. There is an important relationship between the ecological and genetic factors that influence the growth of Brassica rapa (Mitchell-Olds 1996). So, the environmental elements, as well as the genetic information, are essential to the growth rate and survival of Brassica rapa. This plant is capable of reproducing quickly, and the root systems are usually quite small, although some Brassica rapa have developed larger root systems (Mitchell-Olds 1996). This plant is commonly used in experiments because of its ability to germinate rapidly. Brassica rapa is capable of sprouting within a stage of about two weeks, and this trait allows scientists to perform experiments in a short period of time.
The soda that when you guzzle it, the great flavor fills your taste buds and the bubbles of carbonation explode in your mouth leaving a savory taste in your mouth. Dr Pepper is a very popular soda, that is apart of the Pepsi family. Dr Pepper is in stores all around, and is very popular, so not knowing about it, you'll stand out, but don't worry for reading this will inform you of Dr Pepper. This paper contains writing about the history of Dr Pepper such as; when it came to the world, how it was made, who made it, how has it changed, the flavors of it, and how/what are they, the company, doing now, in 2016.
In the article, “Invasive Plants Sometimes Offer Help Instead of Harm”, they explain that the honeysuckle provide organisms in the are with food (Live Science Staff 2011). The honeysuckle gives animals like birds something to eat. It also feeds other small mammals. They also explain that the honeysuckle gives benefits to a plant species native to the Happy Valley American Nightshade (Live Science Staff 2011). This proves that the honeysuckle does not only provide animals with food but they also provide plant secues with benefits, For these reasons, the Honeysuckle is very good for the environment and shouldn’t be

Humans are responsible for almost all of the invasive plant and animal problems. Many of our problem invasives were (and often still are) planted as landscape plants in New Jersey. These include: Norway Maple, Japanese Barberry, Asian Bittersweet, English Ivy, Mimosa, Wisteria, Japanese Honeysuckle, Bugleweed, Bamboo, Day Lily, Purple Loosestrife, Tansy, and Dame's
It is extremely important to keep the environment free of this invasive species. Amur Bush Honeysuckle becomes so abundant and grows very rapidly that it affects the growth of native plant species. Honeysuckle’s exudate prevents the growing of seeds that influences the growth, survival, and reproduction of other organisms. (Davisjg blog, 2015) Removing the species gives the chance of other native species to grow and better the environment. Furthermore, by restoring the environment of Honeysuckle it
Plant defences are those mechanisms employed by plants in response to herbivory and parasitism. According to Hanley et al. (2007), “the tissues of virtually all terrestrial, freshwater, and marine plants have qualities that to some degree reduce herbivory, including low nitrogen concentration, low moisture content, toxins or digestibility-reducing compounds”. The type of chemical defence may be species specific (Scott 2008). The defences that plants possess may be in the form of chemical production or in the form of physical defences such as thorns or spikes and even through reinforced, rigid leaves. “The compounds that are produced in response to herbivory can either have a direct effect on the attacker itself (e.g. toxins or digestibility reducers), or serve as indirect defenses by attracting the natural enemies of the herbivores” (Bezemer & van Dam 2005). This essay will focus on chemical plant defences and in particular the effects of terpenes, phenolics, nitrogen-based defences as well as allelopathy in plants.
Health effects are prominent in Vietnam veterans but denied by the U.S. Department of Veterans Affairs. As reported in the American Legion Magazine, “The defoliant also is believed to have poisoned many people who handled it or passed through sprayed locations. After the war, a conspicuous percentage of veterans contracted various cancers or diabetes, and birth defects occurred at high rate among their children, VA compensation and care were denied (Carroll).” Denial of these severe diseases and unnatural occurrences by the VA could be construed as a cover-up for the government’s mistake or a truthful disconnect of Agent Orange and the diseases. Research has shown, “Dioxin has been found to be a carcinogen associated with Parkinson’s disease,
In the parable of the mustard seed it is necessary to understand that Christ is comparing the Kingdom of Heaven not with the mustard seed, which is significant in size but with the ultimate process of its growth, when it turns into a big bushy tree, in whose branches flocks of birds find shelter. Birds are a metaphor that stands for the peoples of the world of God, who will find shelter (be saved) in the Church of Christ which was to be founded. The mustard seed, in appearance dead and insignificantly small, the least of all seeds. In the words of the parable the mustard seed is a symbol of the mystery of the resurrection from the dead.
Amaranthus palmeri has cause decreases in crop yields and has affected farmers all across the United States. It is an invasive weed to farmers, money to the herbicide industry, and a complex plant to botanists. The research on this weed is sure to continue and maybe one day there will be a control method that will successfully keep all Palmer Amaranth under control. One day, somewhere in a research setting, someone will unlock the secret to controlling Amaranthus palmeri.
Mustard (Brassica) is a rotational cover or winter annual crop i.e., mostly used in vegetable and as well as production of raw crop. Mustard crops have the potential to prevent weeds, erosion, alleviate soil compaction, soil-borne pests and scavenge nutrients (Clark, 2007). Mustard crops have fastest fall growth, high production of biomass, and nutrient scavenging capability following high insert of cash crops. Field mustard that can be grown as a cover crop alone or in a mix with other Brassica legumes or small grains. Mustard plant is the plant which is mostly used as a food flavoring, as an emetic, diuretic, and for forage, as well as a tropical treatment for inflammatory conditions such as rheumatism and arthritis.
