Centaurea Maculosa also known as the Spotted Knapweed and compared regularly to the Diffuse Knapweed is one of the many invasive species in our country. Invasive species are non-native organisms that have negative effects to our environment and economy and also known as a threat to biodiversity. This noxious foreign plant has many characteristics that give it, its name (Spotted). Mainly it’s so invasive because it reproduces quickly and takes over habit, therefore reducing livestock and wildlife. The Spotted Knapweed; its original name Centaurea Maculosa is a member of the sunflower family, there you might see how some ways they are alike. Spotted Knapweed can grow from 1-4feet tall, and its rigid body is green with traces of black and brown
This lab was designed to determine the identity of “mystery spores” by growing them on an agar lined petri dish and observing them growing over the course. While their growth, we learned about various divisions within kingdom Plantae and their characteristics. Using this information about different divisions within kingdom Plantae and our observations of the mystery spores, we created a phylogenetic analysis comparing the mystery spores with the following divisions: Chlorophyta (green algae), Marchantiophyta (liverworts), Bryophyta (mosses), and Pteryophyta (ferns). According to this analysis, we concluded that the mystery spores belonged to the division Pteryophyta. 2.

Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.
Unable to handle their giant snakes, and unable to find new homes for them, some owners illegally release them into the wild. They are also an invasive species, which means that they are not constrained by natural factors as much as they were in their native habitat. Invasive species have the potential to harm their new environments. The release of Burmese pythons in South Florida is especially troublesome because the subtropical climate and the vast undisturbed habitats of the Everglades enable the species to thrive.
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.
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
Calea zacatechichi belongs to the Compositae family or the sunflower family. Its genus is calea, and it is known as the species zacatechichi. Some of the common names for this plant are Aztec Dream Grass, Bitter Grass, Dream Herb, and Madre. It grows between three feet and four feet eleven inches in height. It was originally found in central Mexico growing in the mountains above 5000 feet. Below are pictures of the plant showing its leaves, its flowers, and the last picture is of the leaves being dried. The chemical analysis of Calea zacatechichi or Aztec Dream Grass has as the primary psychoactive compound, germacranolides. This is the reason for the sharp bitter taste of the herb. The herb naturally produces the following chemicals: “1B-acetoxy-zacatechinolide,

This trimester I read a story called Milkweed by Jerry Spinelli. The story was based around the time of Hitler's reign over Germany. Orphaned at an early age, the main character eventually accepts the identity that his friend, Uri, gives him. Unclear as to whether he is a Gypsy, a “Filthy son of Abraham”(pg.138) or a boy named "Stopthief”(pg.2), he suddenly becomes Misha Pilsudski. While stealing food he meets a young girl named Jianina and eventually befriends her. When Jianina and her family is sent off to the Jewish Ghetto, Misha follows. However, soon after they begin to deport Jews and Misha’s makeshift family is eventually taken away leaving Misha and Jianina alone and searching for them. Jianina goes off on her own at some point and
Invasive species, (also known as invasive alien species or simply alien species) are defined as any organism (plant, animal, pathogen, or other living thing) that is alien (non-native) to an ecosystem, which can cause adverse economical, ecological, or health effects to native species and/or humans. The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.
Cotton is an annual, biennial or perennial plant, but in cultivation it is generally treated as an annual; herbaceous to short shrub or small tree - two to six feet tall. It consist of a primary axis, erect and branched with a vegetative lower zone having monopodial branches, and a fruiting upper zone with sympodial branches. The leaves of the cotton plant alternate, cordate petiolate, three to nine lobed and palmately veined, with varying size, texture, shape and hairiness. The large, showy, cream yellow, red or purple flowers are extra axillary, terminal, solitary, and borne on sympodial branches. The calyx (= collectively the sepals) consists of a very short cup-shaped structure at the base of the corolla. The five petals of the corolla are either free or slightly united at the base of the convoluted bud (Sundararaj, 1974).
The pigweed is a quickly evolving weed in the farming industry. Scientifically, this plant is known as Amaranthus palmeri S. Watson. Amaranthus comes from the Greek for evergreen or unfading. This plant was first described by Sereno Watson in the late 1800s. However, it was named after Edward Palmer, who actually discovered the plant earlier in the same century. This is where the palmeri of Amaranthus palmeri was derived. The pigweed is also known by other names such as, Carelessweed and Palmer’s Ameranth. The classification of this plant is very intricate. It is in the Domain Eukarya, the Kingdom Plantae, the sub-kingdom Tracheobionta, the superdivision Spermatophyta, the division (Phylum) Magnoliophyta, the class Magnoliopsida, the subclass Caryophyllidae, the order Caryophyllalus, the family Amaranthaceae, the genus Amaranthus L., and the species Amaranthus palmeri. There are no other sub-species or varieties of this taxon.
One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
