Bush Honeysuckles Bush Honeysuckles are inavasive species plants that grow quickly and agressivly diplacing other Plants. Bush Honeysuckles are harmful to plants, mammals, and wildlife. Of the roughly 2,300 inavasive plant species in Indiana, 25% are non native and are responsible for degrading and destroying thousands of acres of our natural plant communities of Indiana. Bush Honeysuckles where introduced to Northern America in late 1800s and 1900s. They are now reported to be found in 81 counties in Indiana.
1) This hostile takeover changed the EHB’s genetic code. The Africanized honey bee has also been called “killer bee” due to its’ unique defense system that has killed over a thousand people. It is not that AHB’s have more powerful venom but that they attack
The pollen which remains on their hind legs is transferred from flower to flower, allowing pollination of the flowers. This relationship is vital for the production of flowers as well as the pollen source to sustain bee populations. Bee populations have been studies in both North America and Europe and a drastic decline in numbers has been recorded (Muller et. al 2005). Populations are under increasing threats from humans by fragmentation of habitat, agricultural practices, chemical use such as pesticides and herbicides, invasive non-native plants, and disease caused mainly by the use of commercial bees for honey and other products (Kearns et.
MLT1 Experiment 11/Task 8 According to Betsy and Keogh (2005), the three elements necessary for the spread of infection are: a reservoir, a portal of entry and a portal of exit. A reservoir is any place which can harbor a pathogen and where a pathogen can sustain its ability to potentially infect a host. Any of the following could be a reservoir: people, animals, non-living substances (such as soil) and inanimate objects (such as toys and door knobs). Where a disease or pathogen enters the body is known as the portal of entry and where a pathogen exits the body is known as the portal of exit. The portal of entry and the portal of exit are virtually the same and include: the respiratory tract, digestive tract, urinary tract and the skin.
Chloe Mott Block 2A November 15, 2011 Ignorance is Lethal Rachel Carson, a biologist, wrote a book entitled Silent Spring that helped change American’s attitudes about their environment. In the Silent Spring passage Carson describes how farmers rid themselves of vexing or inconvenient creatures, a majority of them being birds. The farmers kill the birds by spraying a poison called parathion, which is capable of “protecting” the area in which it is administered for extended amounts of time. In the passage, Carson provides all three types of rational appeals-ethical, logical and emotional- in an effort to raise awareness and encourage action about the issue of using poisons that have the potential to kill animals. She expresses these appeals by using various rhetorical strategies such as diction and syntax.
Bio 100 Homework due 11/05/12 Name : Nicholas Oliveira Go to the website on cheetah conservation www.Cheetah.org and read the following sections under the tabs About Cheetahs: Intro, Genetic Diversity, & Race for Survival 1. Why are cheetahs endangered? Our attitudes and misconceptions about these species have led to their endangerment because many people deal with their fear by eliminating predators. 2. What are the 5 most common causes of extinction?
Alligators and they get trapped within the hydrilla. Limpkins, because their primary food source, apple snails, are dying out in the Wakulla Springs ecosystem. Apple Snails and they are being battled because the hydrilla halts the snails as they ascend to the surface, so they drown. Some of the methods that have been used and that have failed are using dip nets, booms, hand pulling and mechanical harvesters The method that is being used now is putting herbicide within the spring. “Hydrilla was imported
The cane toad or Bufo Marinus is native specie to Central America and South America. In 1935, after the cane toad was intentionally introduced from Hawaii, the species began its ecologically sustainable control of the insects (greyback beetle, frenchi beetle) threatening commercial sugar cane, it continued to eradicate, but in a form as a problematic issue. Due to the animal’s large dominant size, reproductive capabilities, generalized eating habits and aggressive behavior, the cane toad phenomenon went from good to disastrous, providing a threat to biodiversity. The cane toad has been reclaimed as an ecological disaster after it has mounted a very successful intrusion into Australia and many other countries around the world. In addition,
Michael Pollan suggests how industrial food system is unsustainable because of monocultures, which means a lot of the same species are grown together and that’s only possible by using antibiotics to keep them alive. To keep crop healthy, fertilizer is needed. For example, in Iowa, all the farms were corn and soybeans, which are for industrial use mainly. Separating the animals from the farms raises a huge sanitation problem and the animals are not happy with the conditions, a pollution problem occurs as well. Society is obsessed with productivity becoming cheap, which has made more problems regarding pesticides.
Colony Collapse Disorder The colony collapse disorder of honeybees has become a very problematic issue. The Natural Resources Defense Council states that nearly that nearly one-third of all honeybee colonies in the country have vanished, putting many fruits and vegetables at risk. A controversial type of pesticide called neonicotinoids has become a prime suspect in this phenomenon, as it affects bees’ sense of direction and making it hard for them to find home. In order to prevent this disaster from continuously occurring, neonicotinoids should be banned or used more sparingly and replaced with an alternative type of pesticide. Author Brandon Keim, author of article “Controversial Pesticide Linked to Bee Collapse” states neonicotinoids began to be used in the mid-1990s as less-toxic alternatives to human-damaging pesticides.
