Honors Biology Project Part One By: Logan Lazaras The ecosystem that is being studied in this particular assignment is deforestation. Deforestation occurs in many places all around the world. However, we will be discussing the affects of deforestation in the South African rainforest. This is a threat to many species within the destructed region. Trees and toucans are going to be the species studied during the report.
Host The host range of root-knot nematodes is so extensive that it is difficult to find common landscape and garden plants that are not hosts. Many vegetables, bedding plants, shrubs and trees are susceptible. Symptoms/signs Infections by root-knot nematode cause decline in the host, and under some conditions, may kill the plant. Infected plants may be stunted and chlorotic, usually wilt easily, and are not productive. However, the extent of damage caused by root-knot nematode infections varies with host, timing of infection, and cultural conditions.
English 150 – Research Essay 1 December 2009 The Effects of the Pine Beetle Infestation in BC British Columbia is a province known for its beautiful forests filled with tall, green pine trees. However, today these forests are not so beautiful due to the mountain pine beetle infestation. The mountain pine beetle, otherwise known as “[d]endroctonus ponderosae, is a small insect, less than a centimeter long, which lives most of its life under the bark of pine trees, including lodge pole, ponderosa and western white pine”(Natural Resources Canada). Ordinarily the pine beetle plays a meaningful role in the life of a forest as they help the forest by “attack[ing] old or weakened trees, speeding the development of a younger forest. However, [that is not the case today.]
Both Boscastle and Thailand were at the foot of steep slopes. Steep slopes mean that rainwater will run straight off the surface. Deforestation is also a major factor in this. Ten years ago Thailand was a home to many natural vegetation and forests. However due to illegal logging and the government’s agricultural policy, it had resulted in the loss of many forests.
Hayes argued, “the impacts of atrazine on amphibians and on wildlife in general are potentially devastating” (Hayes et al. 4). Atrazine causes disease and deformities and is a threat to both humans and wildlife. Atrazine is the most common pesticide contaminant of ground and surface water that can spread a half million pounds of atrazine more than 1,000 km from the point of application via rainfall (Hayes et al. 1).
Also harvested and burned to be used in _______ _ Plants C. Plant Functions a) Plants in the Savanna regions are highly specialized to grow in this region during long periods of drought b) They have long tap roots that can reach the deep water table, thick bark to resist forest fires, trunks that can store water, and leaves that _______ off during the winter to conserve water. c) Some plants have sharp thorns, or a __________ taste to discourage animals from feeding on them. D. Animals of the Savanna 1. Aardwolf (__________________________) a) Long, furry hyena that has long front legs and short front legs b) Carnivore but also an __________________. c) Feeds mostly on Harvester termites, Insect Larvae, and eggs of ground nesting birds d) Has a rancid odor to that of a __________.
As it happens, the poplar is a tree liked by the beetle, along with maple, birch, elm and several other hardwoods. The beetle is unique among invasive forest pests for attacking such a broad array of hosts, which is partly why it is so dangerous. Solutions: to control the Asian long horned beetle is to remove infested trees and destroy them through chipping and burning. To easily get rid of the beetles it depends on early notice of infestation and rapid tree removal. There isn’t any really more solutions so far that can help to control the beetles and get rid of them but one solution I made from doing research is that is if you come in contact with a tree that has been infested with the beetle or seen one in a tree the best you can do is contact one of the Canadian forest service.
The ecology of the Pacific Northwest is very interesting. Animals and plants are the reason why it is how it is today. An animal in the Pacific Northwest ecology is the Northern Spotted Owl. This owl is an endangered animal and is one of three subspecies of spotted owls.It is dark to chestnut brown in color with white, round spots all around its neck, back, head, and under parts. Their natural habitats are old-growth forests and these can be found in places that range from northern California, all the way to British Columbia, Canada.
Infection of virus 4. Neonicotinoids C. Thesis: However, to closely look at human cause, Neonicotinoid insecticides are considered by many scientists as the primary factor responsible for the ongoing collapse of honeybee colonies. III. One of the main cause of CCD—Neonicotinoids A. Its application in agriculture B.
Introduction: The reasons for this study it to show the effect of acid rain on plants more specifically sunflower, radish, and clovers. The hypothesis is that the plant would ether die or be severely damaged due to constant exposure of the acid rain. With that in mind there is already historical evidence showing how exposure to Acid rain has caused damage in forests. One example is the Great Smoky Mountains national parks were acid rain has damaged and or kill an entire section of the forest. The reason to do this experiment is to show awareness towards this growing environments problem that is killing many important environments and ecosystems.
